● Xigasho:
Hydroxypropyl methylcellulose (HPMC) waxaa loo yaqaan polymer-ka biyaha-milmi kara, laakiin ku milmideeda dareerayaasha organic iyo hababka dareeraha isku dhafka ah waxay si siman muhiim ugu yihiin daaha, dawooyinka, dhismaha, iyo qaababka gaarka ah. Fahamka sida HPMC ugu dhaqmo khamriga, ketones, iyo biyaha-isku-darka noolaha waxay ka caawisaa hab-sameeyayaasha inay doortaan fasalka saxda ah, naqshadeeyaan nidaamyo xasilloon, iyo inay ka fogaadaan dhibka abuurka ama roobabka.
HPMC waa unug unug-cellulose ah oo aan-ionic ahayn oo lagu helo iyadoo kiimiko ahaan wax looga beddelayo cellulose-ka dabiiciga ah ee methoxy iyo kooxaha hydroxypropyl, taasoo siinaysa milanka xakamaynta iyo guryaha samaynta filimada. Heerka beddelka (DS) iyo miisaanka kellikuyuutarku waxay si xooggan u saameeyaan viscosity-keeda, milanka dareeraha organic, iyo waxqabadka adeegsiga dhamaadka-isticmaalka.
Sababtoo ah HPMC waxaa si weyn loogu isticmaalaa hoobiyeyaasha dhismaha, daawooyinka, cuntada, daryeelka shakhsi ahaaneed iyo dahaarka, xulashada dareeraha waxay si toos ah u saameysaa wakhtiga kala dirida, caddaynta xalka, iyo waxtarka habaynta. Iibsadayaasha OEM iyo soo-saareyaasha, doorashada hababka dareeraha ku habboon ee HPMC waxay muhiim u tahay in la gaaro tayada joogtada ah iyo rheology la saadaalin karo ee wax soo saarka.
HPMC aad bay ugu milmi kartaa biyaha qabow, halkaas oo ay ku firdhiso, bararaan, oo ay milaan si ay u sameeyaan xalal cad ama wax yar oo turbid ah. Xalalkan aqueous waxay muujinayaan kulaylka kuleylka: HPMC gels ama waxay noqonayaan kuwo aan milmi karin heerkulka sare oo ku noqda xalka mar la qaboojiyo.
HPMC waxay ku sii milmi kartaa pH ballaaran oo qiyaas ahaan 3-11 ah, taas oo taageerta isticmaalkeeda qaabab kala duwan iyada oo aan la lumin milanka daran. Darajooyinka cabbirka qashin-qubka ayaa fuuq-baxa oo si dhakhso ah u milma, markaa waxaa la door bidaa marka loo baahdo diyaarinta xal degdeg ah.
Walxaha dabiiciga ah ee saafiga ah, HPMC caadi ahaan lama milmi karo ama wax yar uun bay milmi kartaa, gaar ahaan warbaahinta aan polarka ahayn sida hydrocarbons ama dareerayaasha koloriinaysan. Waxay tusinaysaa in si ka fiican ay ula jaanqaadi karaan dareerayaasha organic polar iyo, tan ugu muhiimsan, isku darka dareeraha dareeraha ee biyaha-organic sida ethanol–biyaha ama propanol–biyaha.
Isku dheellitirnaanta hydrophilic-hydrophobic-ka polymer-ka, dalooliyaha dareeraha ah, awoodda isku-xidhka hydrogen-ka, iyo heerkulka si wadajir ah ayaa go'aamiya in HPMC ay milmi karto, barariso, ama ay samayso ka joojinta. Nidaamyo badan oo warshadeed, HPMC si buuxda uguma milmi dareerayaasha organic saafiga ah laakiin wali waxa loo isticmaali karaa isku darka dareeraha isku dhafan si ay awood ugu yeelato samaynta filimada ama xakamaynta viscosity.
Aalkolada Polar ayaa ah kuwa ugu badan ee looga hadlo dareeraha dabiiciga ah ee HPMC, oo inta badan keligood loo isticmaalo qadar yar ama lagu daro biyo.
- Methanol
- milanka hoose ilaa dhexdhexaad ee methanol saafi ah, iyadoo ku xidhan darajada; milmayntu waxay ku hagaagtaa isku dhafka methanol-biyaha.
- Sunta iyo ololka ayaa xaddidaya isticmaalkeeda dawooyinka iyo cuntada, sidaas darteed waxaa inta badan lagu arkaa xaaladaha warshadaha ama shaybaadhka.
- ethanol
- HPMC guud ahaan waxa ay muujisaa milmi hooseeya ee ethanol-ka saxda ah laakiin kala dirida nidaamka biyaha ethanol-ka oo soo roonaaday.
Isku darka ethanol-biyaha ayaa si weyn loogu isticmaalaa daaha iyo nidaamyada dahaarka filimada, dheellitirka isbeddelka, badbaadada, iyo milanka HPMC.
- isopropanol (IPA)
- HPMC waa la milmi karaa ama si fiican ayaa loogu kala firdhi karaa IPA iyo IPA-biyo isku dhafka ah; darajooyinka qaarkood waxay ogolaadaan in xaddi sare oo HPMC ah loo uruuriyo.
- Nidaamyada IPA waxay ku badan yihiin dahaarka dawooyinka iyo daryeelka shakhsi ahaaneed halkaas oo loo baahan yahay qalajin degdeg ah iyo viscosity kantaroolan.
Ketones-ku waxay muujinayaan dabeecad kakan, oo inta badan u baahan xal-wadayaal ama wax ka kooban biyo.
- Acetone
- Darajooyin badan oo HPMC ah waa kuwo aan la milmi karin ama in yar oo keliya ayaa ku milmi kara acetone saafi ah, in kasta oo ay barari karaan ama kala firdhi karaan.
- Isku darka biyaha-acetone, HPMC waxay ku milmi kartaa ama samayn kartaa filimaan cad, taas oo ka dhigaysa isku dhafkan muhiim u ah dahaarka iyo nidaamyada siideynta la kantaroolo.
- Methyl ethyl ketone (MEK)
- MEK waxay noqon kartaa qayb ka mid ah isku darka dareeraha halka HPMC ay ku milanto ama si fiican u kala firdhiso iyada oo loo marayo isku-darka iyo biyaha.
- Xalka adag iyo uumiga dhaqsaha badan waxay taageeraan nidaamyada qalajinta degdega ah, laakiin dhinacyada badbaadada iyo sharciyaynta waa in la tixgeliyaa.
- Chloroform, dichloromethane (DCM), hydrocarbons
-HPMC guud ahaan waa mid aan lagu milmi karin kuwan aan polar-ka ahayn ama kuwa daciifka ah, inkastoo laga yaabo in loo isticmaalo habab ka kooban qaybo badan oo leh xalal ku habboon.
Qaar ka mid ah hababka dahaarka filimada, DCM ama dareerayaasha la midka ah ayaa lagu daraa isku-darka polar-ka iyo balaastikada halka HPMC uu u dhaqmo sidii filim hore oo nidaamka isku dhafan.
- Glycols iyo glycol ethers
- Glycols iyo glycol ethers waxay faa'iido u leeyihiin sida isku-darka, kor u qaadida kala firdhinta HPMC iyo milanka nidaamyada biyaha.
- Waxay sidoo kale u dhaqmaan sidii balaastiig, hagaajinta dabacsanaanta filimada HPMC waxayna yareeyaan dildilaaca dahaarka.
Dhowr cabbir qaabeyn ayaa xakameynaya in HPMC ay si sax ah u milmi doonto ama ay sababi doonto arrimo ay ka mid yihiin isku urursi, kala dirid aan dhameystirneyn ama roobab.
1. Miisaanka molecular iyo heerka viscosity
- Miisaanka unugyadu sareeyo (viskosity sare) HPMC guud ahaan waxa ay tusinaysaa milanka hoose iyo kala diridda gaabis ah ee hababka dareeraha organic.
- Darajooyinka viscosity hoose si dhaqsiyo leh ayay u milmaan waxaana la door bidayaa qaabaynta adag ama dhaqsaha leh.
2. Darajada beddelka (DS)
- Beddelka methoxy-ka sare iyo hydroxypropyl wuxuu wanaajin karaa laqabsiga dareerayaasha organic polar qaarkood.
- DS si taxadar leh loo xushay waxay awood u siinaysaa dheellitirnaanta udhaxaysa milanka biyaha, waafaqid organic, iyo habdhaqanka kulaylka.
3. Kala-duwanaanta iyo isku-xidhka hydrogen
-Malka HPMC waxa ay u janjeertaa inay ku korodho polarity dareeraha iyo awooda isku xidhka hydrogen, sida caadiga ah ka dib biyaha> methanol> ethanol> acetone> dareerayaasha aan polar-ka ahayn.
- Dejinta hababka dareeraha isku dhafan waxay suurtogal ka dhigaysaa in la hagaajiyo heerka uumiga, milanka, iyo sifooyinka filimka isku mar.
4. Habka heerkulka iyo kala dirida
- Kor u qaadista heerkulka inta badan waxay wanaajisaa kala firdhisanaanta iyo bararka isku dhafka dabiiciga ah, laakiin heerkul aad u sarreeya ayaa kor u qaadi kara xaalufka ama xaalufka polymer.
- Farsamooyinka sida isku dhafka sare ee dhogorta, magnetic ama ultrasonic kicinta waxay dedejiyaan kala dirida waxayna caawiyaan ka fogaanshaha xad-dhaafka ah.
5. Joogitaanka waxyaabaha lagu daro
- Surfactants, balastizers, iyo co-solvents waxay wanaajin karaan qoynta iyo milanka laakiin sidoo kale waxay bedeli karaan viscosity, pH, ama dabeecadda wajiga.
- Waa lama huraan in la sameeyo imtixaanada iswaafajinta iyo xasiloonida si looga fogaado roobab aan la qorshayn ama kala go'in weji waqti ka dib.
Si loo taageero naqshadeeyayaasha, shaxda hoose waxa ay soo koobaysaa hab-dhaqanka caadiga ah ee HPMC ee noocyada dareeraha waaweyn. Qiimuhu waa tayo waxayna ku xidhan yihiin darajada iyo naqshadaynta.
| Solvent/Nidaamka | Caadiga ah ee HPMC Tusaalaha | Kiis Isticmaalka Dhaqanka |
|---|---|---|
| Biyo qabow | Solubility sare, xal viscous cad | Isku darka dhismaha, xalalka farmashiyaha |
| Biyo kulul | Gelation / milanka oo yaraada | Nidaamyada jelka kulaylka, viscosity la xakameeyey |
| Ethanol (dhab ah) | milmays hooseeya ama barar kaliya | Dahaarka waxaa lagu daraa biyo ama glycols |
| Ethanol-biyo isku dhafka ah | Dhexdhexaad ama milmi wanaagsan | Dahaarka filimka, buufinta, khadadka |
| Methanol (absolute) | Hooseeyo ilaa dhexdhexaad ah | Nidaamyada shaybaadhka ama warshadaha (aan cuntada ahayn) |
| IPA iyo IPA-biyo | Kala dirid ama kala firdhisanaan wanaagsan | Dahaarka farmashiyaha, buufinta daryeelka shakhsi ahaaneed |
| Acetone (dhab ah) | Aan milmi karin ama aad u hooseeya | Isku darka dareeraha, barar dhexdhexaad ah |
| Acetone - isku dhafka biyaha | Kala diris/samaynta filimka oo la hagaajiyay | Dahaarka-sii daynta la xakameeyey |
| DCM / chloroform | Guud ahaan aan la xalin karin | Loo isticmaalo oo kaliya isku dhafka adag ee isku-dhafan |
Natiijooyinka joogtada ah, naqshadeeyayaasha waa inay raacaan tillaabooyinka kala dirida habaysan halkii ay si fudud ugu shubi lahaayeen budada dareeraha. Hoos waxaa ah nidaamka guud ee hababka biyaha-khamriga.
1. Ku sii kala firdhi HPMC ee dareere aan dareere ahayn ama liidata
Si tartiib ah ugu dar HPMC aalkolo (tusaale, ethanol ama IPA) halkaas oo ay ku leedahay milmayn xaddidan, hoos walaaqid, si looga hortago samaynta kuusku.
- Faafintan ka hor waxay hubisaa in qaybuhu si buuxda u qoyseen ka hor fuuq-baxa.
2. Ku dar biyo si tartiib tartiib ah hoosta hoostiisa
- U soo geli biyo qabow si tartiib ah slurry-ka hore loo kala firdhiyey; Marka maadada biyuhu korodho, HPMC way fuuqisaa oo milmaan.
- Ilaali isku dhafka xoogga leh si aad uga fogaato isku-duubnaanta gudaha iyo isku-ururinta jel.
3. Xakamaynta heerkulka
- Isku darka ka dhig mid ka hooseeya heerkulka gelation kulaylka inta lagu jiro milanka si looga fogaado samaynta jel dhicis.
- Kadib kala diri buuxda, waxaad hagaajin kartaa heerkulka baahida habka, waase haddii nidaamku uu ahaado mid deggan.
4. Hagaaji pH iyo waxyaabaha lagu daro
Hubi in pH ay ku jirto xadka xasilloon (qiyaastii 3-11) si loo ilaaliyo milanka.
- Ku dar balaastikada, surfactants ama maaddooyinka firfircoon si tartiib tartiib ah, la socoshada viscosity iyo muuqaalka si loo ogaado arrimaha ku habboon goor hore.
5. Shaandhaynta iyo dhegaha
- U gudub xalalka shaandhada ku habboon si aad uga saarto walxaha aan la milmin marka loo baahdo.
- Deaerate by taagan ama faakuum khafiif ah si loo yareeyo xumbo, gaar ahaan dahaarka iyo filimada.
Kiniiniyada iyo kaabsaloyinka, HPMC waa polymer-samaynta filimada muhiimka ah oo loo isticmaalo isku darka biyaha-ethanol ama biyaha-acetone si loo gaadho qalajinta degdega ah iyo viscosity-ka la kantaroolo. Balaastiijiyeyaasha iyo midabada ayaa lagu daraa xalka HPMC si loo hagaajiyo dabacsanaanta, dhejinta iyo muuqaalka dahaarka.
Sababtoo ah dareerayaasha haraaga ah ayaa si adag loogu habeeyey daawooyinka, qaabeeyayaasha waa inay isku dheelitiraan milanka HPMC, xawaaraha qalajinta, iyo xaddidaadaha sharciyeynta marka la dooranayo isku darka dareeraha. Xulashada dareeraha saxda ah iyo xakamaynta habka waxay kaa caawineysaa inaad iska ilaaliso cilladaha sida midabka liin-miilaha, diirka, ama dabool aan dhamaystirnayn.
Dahaarka dhismaha iyo warshadaha, HPMC waxay u shaqeysaa sidii dhumuc weyn, wakiilka biyaha haynta, iyo wax ka beddelka rheology, inta badan hababka isku darka biyaha iyo alkolada ama glycols. Xalkan isku dhafan waxay hagaajiyaan samaynta filimada, wakhtiga furan, iyo shaqaynta iyadoo la ilaalinayo heerarka VOC.
Marka HPMC lagu isticmaalo isku-xidhayaasha kale ama resins, qaabeeyayaasha waa inay xaqiijiyaan in isku darka dareeruhu uu ilaalinayo dhammaan qaybaha inay iswaafaqayaan oo ay ka hortagaan kala-soocidda wejiga muddo ka dib. Tijaabada cabirka tijaabada ahi waa lama huraan si loo ansixiyo sifooyinka codsiga sida simida, caabbinta sag, iyo buufinta.
1. Barar iyo kala dirid aan dhamaystirnayn
Sababta: Ku-daridda HPMC si degdeg ah dareere aad u fuuq-baxaya ama aan bixinayn kicin ku filan.
Xalka: Ku sii kala firdhi dareere liidata (tusaale, alkohol), ku dar biyo si tartiib ah, isticmaal walaaq ku filan ama qalab dhogorta sare leh.
2. Wejiga kala goynta ama roobabka
Sababta: Himilada HPMC oo aad u saraysa, isku darka dareeraha aan la jaan qaadi karin, ama pH/heerkulka oo aan wanaagsanayn.
- Xalka: Hoos u-dhigista polymer-ka, kor u qaad saamiga dareeraha, oo xaqiiji xasilloonida xaaladaha kaydinta.
3. Samaynta jel aan la rabin
Sababta: Ka gudubka heerkulka gelitaanka kulaylka ama isticmaalka darajo leh qaab beddelaad aan ku habboonayn habka dareeraha ee la doortay.
- Xalka: Xakamee heerkulka habaynta oo dooro darajo DS iyo viscosity-ku ay ku habboon yihiin astaanta kulaylka ee qaabaynta.
4. Viscosity oo ku dul wareegaya nolosha shelf
- Sababta: fuuq-bax tartiib tartiib ah, isbeddelka pH ama isdhexgalka waxyaabaha lagu daro inta lagu jiro kaydinta.
- Xalka: Samee tijaabooyinka xasiloonida muddada-dheer, kontoroolka pH, oo kor u qaad isku xigxiga iyo uruurinta wax-ku-darka.
Soo saaraha ether-ka cellulose ee khaaska ah wuxuu bixin karaa wax ka badan xaashida xogta alaabta caadiga ah isagoo siinaya xulashada fasalka, tijaabada shaybaadhka, iyo qaabaynta ku habboon nidaamyada dareeraha ka kooban. Iyada oo la hagaajinayo heerka beddelka, cabbirka walxaha iyo viscosity-ka, soosaarayaashu waxay naqshadayn karaan darajooyinka HPMC ee loogu talagalay daahaarka ethanol-biyaha, buufinta ka kooban IPA, ama dahaarka dawooyinka isku dhafka ah ee acetone.
La shaqaynta alaab-qeybiye xirfadle ah waxay sidoo kale siinaysaa helitaanka tayada joogtada ah, tijaabinta codsiga, iyo cilad-raadinta farsamada, yaraynta khatarta wax-soo-saar la'aanta marka kor loo qaadayo shaybaar ilaa warshad. Tani waxay si gaar ah muhiim ugu tahay codsiyada qiimaha sarreeya ee daawooyinka, cuntada, iyo alaabada dhismaha ee gaarka ah halkaas oo soo saarista iyo u hoggaansanaanta sharciga ay muhiim tahay.
Haddii aad horumarinayso qaabab ku tiirsan milanka HPMC ee dareerayaasha organic ama hababka biyaha isku dhafan, kooxdayada farsamada ayaa kaa caawin kara inaad soo gaabinayso wakhtiga horumarinta iyo hagaajinta xasiloonida habka. Nala wadaag nidaamka dareeraha bartilmaameedka ah, viscosity loo baahan yahay, heerkulka habaynta iyo codsiga dhamaadka-isticmaalka nala, waxaanan kugula talin doonaa HPMC, HEMC iyo darajooyinka HEC ku habboon, ku siin doona hagida kala dirida shaybaarka, iyo taageer tijaabooyinka tijaabada si aad si dhakhso ah uga guurto fikradda shaybaadhka una guurto wax soo saarka warshadaha xasilloon.
Nala soo xiriir si aad u hesho macluumaad dheeraad ah!
HPMC waxay caadi ahaan muujisaa milmayn hooseeya ama barar kaliya ee ethanol ama acetone saafi ah waxaana laga yaabaa inaanay samayn xal cad oo la taaban karo. Codsiyada badankooda, soo-saarayaashu waxay isticmaalaan ethanol-biyaha ama acetone-biyo isku-dar ah halkaasoo HPMC ay si buuxda u milmi karto.
HPMC waxa ay muujisaa kulaylka, taas oo la macno ah in ay si fiican ugu milanto biyo qabow laakiin waxa ay u egtahay in ay samaysato jeel ama ay noqoto mid aan milmayn marka heerkulku kor u kaco heer cayiman. Marka nidaamku mar kale qaboojiyo, jelku wuxuu ku noqon karaa xalka, taas oo ah sababta borotokoollada kala diriddu ay xoogga saaraan ku darida biyaha qabow iyo xakamaynta heerkulka.
Burooyinku waxay dhacaan marka qaybaha HPMC ay si degdeg ah u dareeraan dusha sare, iyagoo ku xannibaya koodhka qallalan ee gudaha. Horey u kala firdhinta HPMC ee wejiga alkohol, si tartiib ah ugu daraya biyo qabow kacdoon xoog leh, iyo isticmaalka darajooyinka cabbirka walxaha wanagsan ayaa ah siyaabo wax ku ool ah oo looga fogaado bararka.
Haa, HPMC waxaa si weyn loogu isticmaalaa daaha ka kooban biyo-organic dareere dareere ah, u dhaqma sidii dhumuc, xasiliye iyo filim hore. Nidaamyada aan biyaha lahayn ee saafiga ah ayaa aad u dhib badan, sidaas darteed dahaarka waxay caadi ahaan ku tiirsan yihiin biyaha, alkolada iyo glycols si ay u bixiyaan milanka HPMC ku filan iyo sameynta filim.
Waa inaad la xiriirtaa halabuurka dareeraha, viscosity bartilmaameedka, cabbirka heerkulka ka baaraandegga, pH, iyo codsiga la rabo sida daahan kaniiniga, buufinta, hoobiye, ama rinjiga. Macluumaadkani wuxuu u oggolaanayaa alaab-qeybiyaha inuu ku taliyo darajooyinka HPMC ee ku habboon oo uu bixiyo habraacyada kala dirida ee ku habboon qaabayntaada gaarka ah iyo habka wax soo saarka.
