Dereaserayaasha warshaduhu waa inay ka saaraan saliidaha culus, saliidaha, kaarboonka haraaga, dareerayaasha mishiinka, faraha, iyo carrada wax soo saarka iyadoo la ilaalinayo qaab-dhismeed dareere ah oo deggan oo sahlan in la isticmaalo. For formulators, doorashada u dhexeeya HPMC vs HEMC kuma koobna viscosity. Waxay si toos ah u saamaysaa iswaafajinta dusha sare, dulqaadka milixda, xasiloonida kaydinta, habdhaqanka xumbo, waxqabadka joojinta, buufinta, iyo xajinta toosan.
Hydroxypropyl Methyl Cellulose (HPMC) iyo Hydroxyethyl Methyl Cellulose (HEMC) waa labadaba ethers cellulose aan-ionic ahayn oo loo isticmaalo in lagu xakameeyo rheology hababka nadiifinta biyaha ku salaysan. Qalabyada warshadaynta sare-sare, labada walxoodba waxay hagaajin karaan jirka wax soo saarka, yareeyaan dejinta, oo abuuraan muuqaal badeecadeed oo joogto ah. Si kastaba ha ahaatee, qaab-dhismeedka beddelkooda ee kala duwan waxay u horseedi karaan kala duwanaansho macno leh oo ku saabsan horumarinta viscosity, caabbinta elektrolytka, habdhaqanka fuuq-celinta, iyo xasilloonida heerkulka.
Nidaamyada nadiifinta warshadaha firfircoon ee firfircoon, ether-ka saxda ah ee cellulose waa in lagu doortaa iyadoo lagu saleynayo caanaha dhamaystiran halkii laga heli lahaa viscosity biyo saafi ah oo keliya. Nooca dusha sare, milixda ku jirta, wax-dhisayaasha alkaline-ka, dareerayaasha, pH, tayada biyaha, habka habaynta, iyo heerkulka kaydinta dhamaantood waxay saameeyaan natiijada kama dambaysta ah.
Nadiifinta warshaduhu waxay inta badan ka kooban yihiin habab kiimiko oo ka adag kuwa caadiga ah ee guriga lagu nadiifiyo. Ujeeddadoodu waa inay burburiyaan saliidaha macdanta culus, saliidaha synthetic, dufanka, dhuka, haraaga warshadaynta, iyo carrada warshadaha ee adag. Si taas loo gaaro, qaabab badan ayaa isku daraa dhowr waxyaalood oo shaqeynaya.
Warshadeeyaha caadiga ah waxaa ka mid noqon kara:
-Anionic surfactants, sida sulfonates, sulfates, ama alfa olefin sulfonates
- Surfactants nonionic, oo ay ku jiraan khamriga ethoxylates iyo wakiilada qoynta xumbo-hoose
- Surfactants Amphoteric, sida betaines
- Dhisayaasha alkaline iyo hagaajinta pH
-Wakiilada qayilaada ee xakamaynta biyaha adag
- Hydrotropes si loo hagaajiyo milanka iyo caddaynta
- Walxaha biyaha-miscible ee la xoojiyey saarista dufanka
- Xakamaynta daxalka ee ilaalinta birta
- Udgoonka, midabaynta, waxyaalaha lagu ilaaliyo, ama lagu daro shaqaynaysa
- Qaybaha la laalay ama qaybaha aan la milmi karin ee nidaamyada nadiifiyaha gaarka ah
Kakanaantani waxay abuurtaa caqabad xasilloon. Dereasiyaha ayaa laga yaabaa inuu marka hore u ekaado mid cad oo isku mid ah ka dib marka la soo saaro, laakiin lumiyo viscosity ka dib kaydinta. Waxa laga yaabaa in ay khafiif noqoto ka dib marka uu soo gaadho heerkul sare, uu yeesho caraf inta lagu jiro kaydinta qaboojiyaha, kala soocida lakabyada, ama u ogolaato qaybo aan milmi karin in ay degaan.
Eter-ka cellulose wuxuu caawiyaa xakameynta khatarahaas iyadoo kordhinaysa viscosity wejiga aqueous iyo abuurista shabakad dareere habaysan oo dheeraad ah. Shabakaddani waxay wanaajin kartaa hakinta walxaha, waxay ilaalin kartaa muuqaal isku mid ah, waxayna ka caawin kartaa alaabtu inay ku sii jirto meelo toosan muddo dheer.
Dhumucdiisuna waxa ugu fiicani had iyo jeer maaha shayga siiya viscosity-ka ugu sarreeya biyaha. Qalabka ugu waxtarka badan waa kan bixiya viscosity la isku halayn karo, muuqaal deggan, iyo waxqabadka codsiga la saadaalin karo ee qaacidada dereaser ee dhammaatay..
Hydroxypropyl Methyl Cellulose, oo loo yaqaan HPMC, waa eter cellulose aan-ionic ahayn oo ay soo saarto wax ka beddelka cellulose leh methoxy iyo hydroxypropyl kooxaha. Waxaa si weyn loo isticmaalaa sidii dhumuc weyn, rheology modifier, kolloid ilaalinta, wakiilka hakinta, xidhe, iyo walxaha samaynta filimada.
Hoos-u-dhacyada warshadaha, HPMC waxay gacan ka geysan kartaa qaab-dhismeed sheyga oo badan oo la xakameeyey iyo jir xoog leh. Waxay si gaar ah faa'iido u leedahay marka alaabtu u baahan tahay inay ku dhegto meelo toosan halkii ay isla markiiba ka baxsan lahayd.
- Hufnaanta dhumucda xooggan ee heerarka qiyaasta qiyaas yar
- Waxqabadka wanaagsan ee ka-hortagga dejinta ee walxaha aan milmi karin iyo carrada la hakiyey
- Ku dheggan toosan oo la hagaajiyay ee dejiyeyaasha nooca jel
- Iswaafajinta dusha sare ee ballaaran sababtoo ah dabeecadeeda aan-ionic ahayn
- Taageerada xumbo waxtar leh ee nidaamka nadiifinta xumbo-xumada
- Alaabooyinka samaynta filimada oo laga yaabo inay gacan ka geystaan ilaalinta xidhiidhka alaabta ee dusha sare
- Xulashada darajada dabacsan ee noocyada viscosity ee kala duwan
HPMC waxay si gaar ah waxtar ugu yeelan kartaa alaabada ay ka midka yihiin jeel-ka-jarida-jikada, nadiifiyeyaasha foornada, jeladaha gacmaha lagu nadiifiyo, nadiifiyeyaasha dayactirka aqoon-is-weydaarsiga, iyo kuwa-dejinta-culus-culus.
Tusaale ahaan, marka nadiifiyaha lagu dhejiyo birta toosan, ilaaliyaha mashiinka, daboolka birta ah, ama qalabka dufanka leh, dareeraha khafiifka ah ayaa laga yaabaa inuu si degdeg ah u dareero. Nidaamka HPMC oo si habboon loo habeeyey wuxuu abuuri karaa xajin badan, taasoo u oggolaanaysa xirmada surfactant iyo alkaline inay sii ahaato xiriirka ciidda muddo dheer.
HPMC isku si uma dhaqmo qaab kasta. Waxqabadkeedu wuu kala duwanaan karaa iyadoo ku xiran:
- Miisaanka molecular iyo heerka viscosity
- Methoxy iyo hydroxypropyl heerka beddelka
- heerkulka biyaha inta lagu jiro habaynta
- Waqtiga fuuq-baxa
- Isku dhafka xawaaraha iyo xaaladaha xiirta
- Walxaha firfircoon ee dusha sare leh
- Milixda iyo xoogga wax-dhisaha
- Heerka dareeraha
- pH kama dambaysta ah
- heerkulka kaydinta
Heerka viscosity-sare ee HPMC waxa laga yaabaa inay keento qaab-dhismeedka jel ka xoog badan, laakiin waxa kale oo laga yaabaa inay u baahato kala firdhisanaan taxadir leh iyo xakamaynta fuuq-celinta. Hababka isku-darka liita waxay sababi karaan agglomerates, kala dirid aan dhammaystirnayn, ama indho-beel aan sinnayn.
Hydroxyethyl Methyl Cellulose, oo loo yaqaan HEMC, waa eter kale oo aan ahayn ionic cellulose. Waxaa lagu soo saaraa iyadoo wax laga beddelayo cellulose leh kooxaha methyl iyo hydroxyethyl. HEMC waxaa si weyn loogu isticmaalaa alaabada dhismaha, dahaarka, alaabada kiimikaad ee maalinlaha ah, saabuunta, iyo hababka nadiifinta biyaha ku salaysan.
Degreasers warshadaha, HEMC waxaa inta badan loo xushay rheology dheeli tiran, texture alaabta siman, kala firdhinta-biyaha qabow, iyo qaabaynta xooggan ee nidaamka ka kooban surfactants, cusbada, iyo daro kale oo shaqaynaya.
- Waafaqsanaan adag oo leh nidaamyada dusha sare ee caadiga ah
- Haysashada viscosity wanaagsan ee qaababka nadiifinta adag
- Waxqabadka wanaagsan ee hababka milixdu ku jirto
- Wax soo saarka siman oo lebbisan
- Taageerada cayrinta lagu kalsoonaan karo ee alaabta aan milmi karin
- Dabeecad wanaagsan oo biyaha qabow ah
- Degenaansho faa'iido leh oo ku jirta alaabada dhexdhexaadka ah iyo dhexdhexaadka ah ee alkaline
- Xakamaynta rheology ee waxtarka leh ee nadiifinta firfircoonida sare leh
HEMC waxaa inta badan la tixgeliyaa marka ay dereaserku leedahay feejignaan sare oo korka ka soo baxa, wax dhisaha muhiimka ah, ama cadaadiska elektrolytka ee milixda iyo maaddooyinka alkaline. Waxa ay si gaar ah qiimo ugu yeelan kartaa nadiifiyeyaasha mishiinada, kuwa baabuurta gooya, alaabta dayactirka aqoon-is-weydaarsiga, nadiifiyeyaasha dareeraha ah ee xoogga leh, iyo hababka nadiifinta isticmaalka warshadda.
In kasta oo HEMC inta badan loo door bidayo caqabadaha nidaamyada dusha sare, waxay weli u baahan tahay tijaabin qaabayn oo dhammaystiran. Waxqabadkeeda waxaa saameyn ku yeelan kara:
- Nooca iyo fiirsashada surfactants
- Qadarka cusbada sodium iyo wax-dhisayaasha alkaline
- Isticmaalka hydrotropes
- Joogitaanka glycol ethers ama dareerayaasha kale
- adkaanta biyaha
- Qalabka hagaajinta pH
- Heerkulka inta lagu jiro wax soo saarka iyo kaydinta
- Cadaynta alaabta loo baahan yahay
- Habka baakaynta iyo qaybinta
HEMC waa in aan la dooran kaliya sababtoo ah waxay caan ku tahay dulqaadka milixda. Heerka saxda ah, qiyaasta, habka fuuq-celinta, iyo waafaqid wadarta caanaha ayaa ah muhiim.
HPMC iyo HEMC labaduba waxay awoodaan inay hagaajiyaan waxqabadka warshadaynta. Doorashada ugu fiican waxay ku xiran tahay codsiga la doonayo iyo arrimaha walaaca qaaciddada.
| Qodobka Waxqabadka | HPMC | HEMC | Aragtida Habboon ee Waxqabadka |
|---|---|---|---|
| Dabeecadda aan-ionic ahayn | Haa | Haa | Labaduba waxay si fiican ugu shaqeeyaan noocyo badan oo surfactant ah |
| Karti dhumucda | Xoog badan | Xoog badan | Fasalka iyo qiyaasta ayaa go'aaminaya viscosity-ga ugu dambeeya |
| Degenaansho sare-surfactant | Wacan oo leh xulasho darajo ku habboon | Inta badan waxay ku xoogan yihiin nidaamyada firfircoon ee sare | HEMC si joogto ah ayaa marka hore marka hore laga baaraa qaacidooyinka la uruuriyay |
| milixda iyo dulqaadka elektrolytka | Wanaagsan laakiin caanaha ku tiirsan | Badanaa ku habboon nidaamyada korantada-ku jira | HEMC waxa laga yaabaa inay bixiso haynta viscosity ka fiican ee alaabta hodanka ku ah wax dhisaha |
| Habaynta biyaha qabow | Waxay u baahan tahay fuuq-bax la xakameeyey | Badanaa waxay bixisaa kala daadsanaan ku habboon biyaha qabow | HEMC waxa laga yaabaa inay fududayso wax soo saarka heerkulka deegaanka |
| Taageerada dejinta ka-hortagga | Xoog badan | Xoog badan | Labaduba waxay kaa caawin karaan xasilinta walxaha aan milmi karin |
| Ku dheggan toosan | Aad ugu fiican alaabta nooca jel | Wax ku ool u ah nidaamyada dhumucyada deggan | HPMC waxaa inta badan laga door bidaa jeelyada ku dheggan ee habaysan |
| Taageerada xumbo | Waxay taageeri kartaa xasilloonida xumbo | Waxay taageeri kartaa dhaqanka xumbo | Xirmada surfactant ayaa weli ah qodobka ugu muhiimsan ee xakameynaya xumbo-xumada |
| Dhaqanka kulaylka | Aad xasaasi u ah sifooyinka gelation kulaylka | Badanaa ku habboon baarista xasilloonida heerkulka sare | HEMC waxay faa'iido u yeelan kartaa qiimaynta kaydinta kulul |
| Diiradda codsiga guud | Jeelka, alaabta ku dheggan, nidaamyada hakinta | Nadiifiyeyaasha firfircoon ee firfircoon, hababka milixdu ku jirto, xoog-saarid deggan | Xulashada kama dambaysta ahi waa inay raacdo imtixaankii la dhammeeyey |
Isbarbardhigga wuxuu muujinayaa in shay kasta uusan ka wanaagsanayn caalamka. Taa baddalkeeda, eter kasta oo cellulose ah wuxuu bixiyaa faa'iidooyin gaar ah oo noqda mid aad muhiim u ah xaaladaha kala duwan ee qaabeynta.
Culaysyada dusha sare leh ayaa dhawr siyaabood u beddeli kara hab-dhaqanka dhumucda. Habayntu waxa ay ka koobnaan kartaa surfactant ku filan si loo nadiifiyo si wax ku ool ah, laakiin isla xidhmada dusha sare waxay saamayn kartaa fuuq-celinta polymerka iyo viscosity-ka.
Surfactants waxay sameeyaan miceles marka xooggoodu gaaro heer gaar ah biyaha. Miceles-yadani waxay lagama maarmaan u yihiin saarista saliidda sababtoo ah waxay caawiyaan hareeraha iyo kala firdhiyaan carrada saliidda leh. Si kastaba ha ahaatee, isla deegaanka micellar-ka ayaa saameyn kara habka silsiladaha ether-ka ee cellulose ay u fuuq baxaan oo ay ula falgalaan biyaha.
Marka fiirsashada dusha sare ay korodho, polymer-ku wuxuu u baahan karaa qiyaas ama darajo ka duwan si loo gaaro viscosity bartilmaameedka.
Dereasers warshaduhu waxay inta badan isticmaalaan cusbada alkaline-ka, wax-dhisayaasha sodium-ku-salaysan, wakiilada-chelating, iyo maaddooyinka kale ee elektrolyt-ka ku jira. Qalabkani waxa ay bedeli karaan deegaanka biyaha ee la heli karo waxaana laga yaabaa inay yareeyaan waxtarka dhumucda.
Polymer-ka si fiican ugu shaqeeya biyaha fuuq-baxay waxaa laga yaabaa inuu u dhaqmo si ka duwan qaabka ay ku jiraan sodium carbonate, sodium metasilicate, sodium citrate, phosphates, ama qalab kale oo wax dhisa.
Hydrotropes waxay gacan ka geystaan ilaalinta caddaynta waxayna hagaajiyaan milanka surfactants iyo maaddooyinka saliidda leh. Xalka biyaha-miscible waxay xoojin karaan saarista dufanka. Si kastaba ha ahaatee, labadaba hydrotropes iyo dareerayaasha ayaa laga yaabaa inay saameyn ku yeeshaan fuuq-celinta polymer waxayna yareeyaan viscosity-ga ugu dambeeya.
Tani waa sababta naqshadeeyayaasha soo saarayaasha warshaduhu aysan ku qiimeyn HPMC ama HEMC biyaha oo keliya. Eter-ka cellulose-ka waa in la tijaabiyaa ka dib marka dhammaan walxaha waaweyn, cusbada, dareerayaasha, wax-dhisayaasha, iyo pH-ga lagu hagaajiyo lagu daro.
Dereaser ayaa laga yaabaa in lagu soo saaro heerkulka qolka oo u muuqda mid deggan. Waxaa laga yaabaa in ay markaas dhex marto meelaha kaydinta kulul, weelasha rarida, bakhaarada, aqoon-is-weydaarsiyada, ama goobaha qaybinta dibadda.
Soo-gaadhista kulaylku waxay sababi kartaa isbeddellada viscosity, daruuro, kala-taag, iyo xasillooni-darro wajiga. Labada HPMC iyo HEMC waa in lagu qiimeeyaa xaaladaha kaydinta dhabta ah, oo ay ku jiraan tijaabinta heerkulka-sare iyo baaskiilada dhalaalaysa meesha ay khusayso.
HPMC inta badan waa musharrax xoog leh marka alaabtu u baahan tahay muuqaal habaysan oo ku dheggan rheology profile. Waxa ay si gaar ah qiimo u yeelan kartaa marka nadiifiyahu u baahan yahay in uu ku sii jiro dusha sare ee toosan, xaglaha ama xagal.
- Jikada-jikada wax-ka-qaboojisa oo culus
- Nadiifiyeyaasha foornada iyo dubista
- Dereasiyeyaasha dusha toosan
- Nadiifiyeyaasha baabuurta ee nooca jeelka ah
- Hoos-u-dhigeyaasha aqoon-is-weydaarsiga gacanta lagu dabaqay
- Jeelasha nadiifinta ee walxaha ka kooban
- Nadiifiyeyaasha xumbo-baxa oo u baahan jir xoog badan
- Alaabooyinka dayactirka warshadaha ee u baahan taageerada dejinta
HPMC waxa kale oo laga yaabaa in la tixgeliyo marka alaabtu u baahan tahay wax la taaban karo oo la taaban karo. Suuqyada qaar, isticmaalayaashu waxay ku xidhaan jidhka wax soo saarka la kantaroolo, ee aan biyaha lahayn oo leh hawl nadiifin adag iyo tayada alaabta oo ka sii fiican.
Tixgeli qaboojiyaha loo isticmaalo qalabka wax soo saarka tooska ah. Nadiifiyuhu waa in uu dul saarnaadaa muddo ku filan si uu u jilciyo dufan engegan iyo hadhaaga saliidda. Haddii alaabtu aad u dhuuban tahay, isla markiiba way dami doontaa. Haddii ay aad u dhumuc weyn tahay, waxaa laga yaabaa in ay adag tahay in la buufiyo, lagu shubo, ama la faafiyo.
Darajada HPMC ee sida saxda ah loo doortay ayaa kaa caawin karta abuurista dheelitirka codsiga iyo xajinta. Natiijadu waxay noqon kartaa-dereaser si fudud u fida laakiin ku sii jira dusha dufanka leh muddo dheer oo ku filan maaddooyinka nadiifinta inay shaqeeyaan.
HEMC inta badan waa doorasho adag oo loogu talagalay soo-saareyaasha warshadaynta firfircoon ee firfircoon oo ay ku jiraan dhowr surfactants, cusbo, wax-dhisayaal, ama hydrotropes. Waxay si gaar ah faa'iido u leedahay marka caanaha ay tahay inay ilaaliso viscosity joogto ah ka dib wax soo saarka iyo inta lagu jiro kaydinta.
- Warshado-soo-saarka warshadaynta oo urursan
- Nadiifiyeyaasha mishiinada dusha sare leh
- Baabuurka iyo alaabta nadiifinta
- Goynta dabaqa warshadda
- Nadiifiyeyaasha dayactirka aqoon-is-weydaarsiga
- Degreasers dareere alkaline khafiif ah
- Saamaynta nadiifinta la milmi karo
- Nidaamyada nadiifinta milix-ku jira ama wax-dhisaha
- Nidaamyada wax soo saarka heerkulka jawiga
HEMC waxa kale oo ay ku haboonaan kartaa habaynta u baahan muuqaal dareere ah oo siman. Degreasers cad ama translucent, xasiloonida muuqaalka ee alaabtu waa muhiim. Cuncun, wasakh, xumbo hawo, ama kala fogaansho muuqata waxay yarayn kartaa kalsoonida iibsadaha xitaa haddii waxqabadka nadiifinta uu ahaado mid la aqbali karo.
Nadiifiyaha qalabaysan ee xooga leh waxa ku jiri kara surfactants anionic, surfactants nonionic, maaddooyinka alkaline, wakiilada chelating, iyo xirmo dareere ah. Alaabta waa in ay ahaataa mid xasiloon inta lagu jiro kaydinta oo ay keentaa viscosity la saadaalin karo ka dib marka la qaso.
Xaaladdan oo kale, HEMC waxa laga yaabaa inay bixiso meel la isku halayn karo oo laga bilaabo sababtoo ah qaaciddada waxay culays weyn saartaa nidaamka rheology-ga. Wax qabadkeeda waa in wali la xaqiijiyo iyadoo la adeegsanayo xirmada dusha sare ee ugu dambeysa iyo xaaladaha kaydinta loogu talagalay.
Isbarbardhigga HPMC vs HEMC waa inuu ku salaysnaadaa waxqabadka qaacidada ah ee la dhammeeyey ee aan ahayn malo. Habka soo socdaa wuxuu kaa caawinayaa dhimista khatarta horumarka.
Kahor intaadan dooran ether cellulose, aqoonso sifooyinka alaabta loo baahan yahay:
- viscosity bartilmaameedka 25°C
- Habka codsiga loo baahan yahay
- Buufinta ama bamgareynta
- Waxqabadka xajinta toosan
- Hufnaanta alaabta la rabo ama mugdiga
- Walxaha firfircoon ee dusha sare leh
- Culayska cusbada iyo wax-dhisaha
- qiyaasta pH
- Heerka dareeraha
- Shuruudaha xumbo
- Heerkulka kaydinta ee la filayo
- Nolosha shelf ee loo baahan yahay
- Saamiga milanka macaamiisha
Bartilmaameed cad ayaa ka hortagaya shaqada tijaabinta iyo khaladka aan loo baahnayn.
Samee qaaciidada dereaser-ka salka leh oo leh surfactant go'an, milix, dareere, biyo, iyo heerarka pH. Kadib diyaari noocyo kala duwan adoo isticmaalaya HPMC iyo HEMC.
Ha barbar dhigin walxaha isku qiyaas kaliya. Taa beddelkeeda, ku barbar dhig isla aragtida bartilmaameedka ah. Mid ka mid ah ether cellulose ayaa laga yaabaa inuu u baahdo heerar dheeri ah oo ka duwan si loo gaaro rheology la doonayo.
Fuuq-celinta aan dhamaystirnayn waxay abuuri kartaa natiijooyin marin habaabin ah. Ka dib marka lagu daro HPMC ama HEMC, u ogolow wakhti ku filan polymerku inuu si buuxda u fuuqbaxo ka hor inta aan la cabbirin viscosity.
Habka fuuq-celinta ee lagu taliyay waa in lagu waafajiyaa darajada la doortay. Xaaladaha qaarkood, kala firdhinta la xakameeyey ee biyaha ka hor inta aan lagu darin maaddooyinka sare-sare waa habka ugu kalsoonaan karo.
Tijaabi soo-dejinta dhamaystiran ee xaaladaha dhabta ah:
- Viscosity hore
- Viscosity ka dib 24 saacadood
- Viscosity 7 maalmood ka dib
- Viscosity 30 maalmood ka dib
- xasilloonida pH
- Muuqashada iyo hufnaanta
- Kala saarida wejiga
- Sedimentation
- xasiloonida centrifuge
- Kaydinta heerkulka sare
- Dejinta baraf-dhalaalid
- Waafaqid biyaha adag
- Dusha oo ku dheggan
- Habka buufinta
- dhaqanka xumbo
- Waxqabadka dufan-saarista
Budada ugu jaban had iyo jeer maaha doorashada diyaarinta ugu fiican. Eter-ka cellulose-ka wax qabadkiisu sarreeyo wuxuu hoos u dhigi karaa qiimaha guud ee alaabta la dhammeeyey haddii ay yarayso dib-u-shaqaynta, hagaajiso joogteynta dufcadda, yarayso wakhtiga habaynta, ama yarayso soo-celinta alaabta.
Tixgeli sawirka qiimaha buuxa:
- Qiyaasta loo baahan yahay si loo gaaro viscosity bartilmaameedka
- Waqtiga wax-soo-saarka
- Kakanaanta isku dhafka
- Heerkulka habaynta
- Dufcaddii soo noqnoqda
- xasiloonida kaydinta
- Waxqabadka baakadaha
- Khibrada macmiilka
- Meelaynta alaabta
Xitaa eter-ka cellulose-ka tayada sare leh ayaa hoos u dhigi kara haddii habka wax soo saarka aan la xakameynin.
Ku darida budada degdega ah waxay abuuri kartaa buro ama indhaha kalluunka. Lakabka sare ee qaybta ether cellulose ayaa laga yaabaa inay isla markiiba fuuqbaxdo, oo ku xayirto budada qallalan gudaha. Agglomerates-yadan ayaa laga yaabaa inay muuqdaan ama u horseedaan korriinka viscosity ee aan dhamaystirnayn.
Dereasiyaha ayaa laga yaabaa inuu u muuqdo mid dhuuban wax yar ka dib marka la isku daro, taasoo u horseedaysa qaabeeyaha inuu ku daro dhumuc dheeraad ah oo aan loo baahnayn. Ka dib fuuqbaxa buuxa, viscosity wuxuu noqon karaa mid aad u sarreeya. Had iyo jeer oggolow wakhti korriin ku filan ka hor inta aanad wax ka beddelin qiyaasta.
Biyaha adag, milixyada kala diri, iyo isbeddelka tayada habka-biyaha waxay saameyn ku yeelan karaan dabeecadda dusha sare iyo viscosity-ga ugu dambeeya. Alaabta la sameeyay iyadoo la adeegsanayo biyaha heerka shaybaadhka ah waa in sidoo kale lagu tijaabiyaa biyaha wax soo saarka dhabta ah.
Warshadeeyayaasha warshaduhu waxay la kulmi karaan xaaladaha gaadiidka kulul, bakhaarada qabowga, iyo baaskiil wadida heerkulka. Alaabooyinka ku xasiloon heerkulka qolka kaliya waxa laga yaabaa inay fashilmaan qaybinta ka dib.
Qiyaasta siman ma bixiso isbarbardhig dhamaystiran. Qalab kala duwan ayaa laga yaabaa inay leeyihiin waxtarka viscosity oo kala duwan. Is barbar dhig shay-baarayaasha marka loo eego viscosity bartilmaameed siman iyo isla shuruudaha qaacidada ee la dhammeeyey.
Akhrinta viscosity sare ma dammaanad qaadayso badeecad wanaagsan. Dereasiyaha sidoo kale waa inuu buufiyaa, shubaa, bamgareeyaa, faafiyaa, dhejiyaa, biyo raaci, oo si waxtar leh u nadiifiyaa.
HPMC iyo HEMC labaduba waa ethers-cellulose aan-ionic ahayn oo qiimo leh oo loogu talagalay soo-saareyaasha warshadaha. Labaduba waxay hagaajin karaan viscosity, jidhka alaabta, xasiloonida ka joojinta, iyo maaraynta isticmaalaha. Doorashada ugu habboon waxay ku xiran tahay culeyska dusha sare ee caanaha, xoogga milixda, nidaamka wax-dhisaha, waxyaabaha dareeraha ah, pH bartilmaameedka, habka codsiga, iyo shuruudaha kaydinta.
HPMC inta badan aad bay waxtar ugu leedahay alaabta jelka habaysan, nadiifiyeyaasha tooska ah, hababka dejinta lidka ku ah, iyo kuwa hoos u dhiga xumbo-jajabinta. HEMC had iyo jeer waa musharrax xoog leh oo loogu talagalay xoog-saarid, koronto-soo-saar sare, milix ku jirta, ama wax-soo-saareyaasha hodanka ku ah warshadaha halkaasoo xasilloonida viscosity ay tahay shuruudda koowaad.
Habka xulashada aadka loogu kalsoonaan karo waa in la is barbar dhigo HPMC iyo HEMC qaacidada dhameystiran ee dhameystiran ee hoos yimaada wax soo saarka, kaydinta, iyo isticmaalka dhabta ah. Eter-ka cellulose-ka ah ee si fiican isku dhafan ayaa hagaajin kara joogteynta alaabta, yaraynta khatarta xasiloonida, xoojinta muuqaalka alaabta, iyo abuurista xal nadiifinta warshadaha oo la isku halleyn karo.
Wixii horumarinta alaabta nadiifinta warshadaha raadinaya xal ether cellulose deggan, Shandong Shengda New Material Co., Ltd. waxay siisaa HPMC iyo qalabka HEMC ee codsiyada qaabaynta kiimikada iyo warshadaha maalin kasta, ay taageerayaan hagitaan xulashada fasalka, muunado alaabta, iyo farsamada qaabaynta dood.
Farqiga ugu weyni waa qaab-dhismeedkooda beddelka kiimikaad. HPMC waxa ku jira kooxaha hydroxypropyl iyo methoxy, halka HEMC ay ka kooban tahay hydroxyethyl iyo methyl. Labaduba waa ethers cellulose-ka aan-ionic ahayn, laakiin waxay muujin karaan habdhaqan fuuq-baxeed oo kala duwan, jawaab-celinta heerkulka, dulqaadka milixda, iyo xasilloonida viscosity ee hababka nadiifinta adag.
HEMC inta badan waa ikhtiyaar bilow adag oo loogu talagalay dusha sare, milix ku jira, iyo kuwa wax dhisa ee qani ku ah kuwa wax dhisa sababtoo ah waxay siin kartaa viscosity deggan nidaamyada biyaha ku saleysan ee adag. Si kastaba ha ahaatee, HPMC waxa laga yaabaa inay si isku mid ah u si fiican ama ka sii fiican u qabato qaabab gaar ah, gaar ahaan marka si toos ah loogu dheggan yahay, qaab-dhismeedka jel, taageerada xumbo, ama waxqabadka ka-hortagga dejinta ay muhiim tahay.
Haa HPMC iyo HEMC waa ethers-cellulose aan-ionic ahayn waxayna guud ahaan la jaan qaadayaan habab badan oo anionic, nonionic, iyo amphoteric surfactant ah. Waafaqid weli waa in lagu tijaabiyaa qaabaynta dhamaystiran sababtoo ah milixdu, dareerayaasha, hydrotropes, pH, iyo tayada biyuhu waxay saamayn ku yeelan karaan waxqabadka ugu dambeeya.
Qiyaasta saxda ah waxay kuxirantahay darajada etherka cellulose, viscosity bartilmaameedka, walxaha firfircoon ee firfircoon, culeyska korantada, waxyaabaha dareeraha ah, iyo habka codsiga loo baahan yahay. Qiyaas hoose ayaa laga yaabaa inay ku habboonaato nadiifiyeyaasha dareeraha ah ee la shubi karo, halka qiyaas sare laga yaabo in loo baahdo jel ku dheggan ama alaabta dejinta. Tijaabadu waa inay had iyo jeer go'aamiso heerka ugu dambeeya ee isticmaalka.
Haa HPMC iyo HEMC labaduba waxay kordhin karaan viscosity-ka hooseeya waxayna abuuri karaan nidaam dareere habaysan. Tani waxay gacan ka geysan kartaa in la hakiyo walxaha aan milmi karin, midabada, abrasives, ama haraaga carrada inta lagu jiro kaydinta.
HPMC iyo HEMC inta badan waxay hagaajiyaan qaab dhismeedka sheyga, rheology, xasiloonida, xajinta, iyo joojinta Waxqabadka dufanka-saarista ee ugu weyn wuxuu ka yimaadaa surfactants, dareerayaasha, maaddooyinka alkaline-ka ah, wakiilada chelating, iyo qaybaha kale ee nadiifinta. Si kastaba ha ahaatee, xajinta hagaajinta waxay kordhin kartaa wakhtiga xidhiidhka oogada waxayna taageertaa waxtarka nadiifinta.
Labada HPMC iyo HEMC waxaa loo isticmaali karaa qaab-dhismeedka xumbo-hoose. Heerka xumbo waxaa inta badan gacanta ku haya xirmada surfactant. Eter-ka cellulose-ka waa in lagu doortaa iyadoo lagu saleynayo xasiloonida viscosity, muuqaalka alaabta, dulqaadka milixda, buufinta, iyo shuruudaha codsiga.
