Viscosity High-viscosity HPMC iyo viscosity hoose HPMC waxay keenaan muuqaalo waxqabad oo aad u kala duwan xagga dhismaha iyo qaabaynta kiimikaad-maalin kasta, laga bilaabo caabbinta sibidhka-xabaglaha ilaa simanaanta budada-saydhka. Sida a Soo saaraha Shiinaha ku salaysan (Shandong Shengda New Material Co., Ltd.) oo ku takhasusay hydroxypropyl methylcellulose (HPMC) iyo ether-yada kale ee cellulose, waxaan fahamsanahay in doorashada u dhaxaysa labadan nooc ee viscosity aysan ahayn oo kaliya 'qararan vs. khafiif ah ' - waxay ku saabsan tahay isbarbardhigga rheology, haynta biyaha, iyo codsiga iska caabinta saxda ah . [linkin ]
Maqaalkan, waxaan is barbar dhigeynaa viscosity sare HPMC iyo viscosity hooseeyo HPMC si faahfaahsan, siinta hagitaan wax ku ool ah hoobiye, tile-dhesive, putty, skim-jaakad, iyo la isku qurxiyo-farmaceutical formulations, si aad u dheelitiri kartaa shaqada iyo iska caabin ah oo aan hurayn kharash ama waxqabadka. [kimachemical ]
Warshadaha dhismaha, viscosity HPMC waxaa caadi ahaan lagu cabbiraa sida mPa·s (cps) ee 2% xal aqueous ah 20 °C . [kemoxcellulose ]
- Viscosity-hoose HPMC caadi ahaan waxa ay tixraacdaa badeecadaha ku jira 400-50,000 mPa·s , oo leh buundooyin badan oo tile-dhesive iyo skim-jaakad ah oo fadhiya agagaarka 40,000-60,000 mPa·s . [kimachemical ]
- Viscosity High HPMC guud ahaan macnaheedu waa ≥100,000 mPa·s , oo leh darajooyin dhismo oo caadi ah 100,000-200,000 mPa·s . [kemoxcellulose ]
Sababtoo ah HPMC waa polymer aan-ionic ahayn, biyo-milmi kara , muuqashadiisu waxay ka tarjumaysaa sida xoogga leh ee silsiladuhu ugu dheggan yihiin biyaha, taas oo iyaduna xukunta haynta biyaha, u janjeersiga filim samaynta, iyo dhaqanka xiirid-dhuuban . [zh.wikipedia ]
Viscosity High HPMC ayaa ka sarreeya halka haynta biyaha, adhesion, iyo caabbinta sagxada ama silbashada ay muhiim u yihiin: [kimachemical ]
- Haysashada sare ee biyaha - darajooyinka viscosity-ka sare waxay sameeyaan shabakad polymer cufan, haysa biyo badan iyo dib u dhigista qalajinta degdega ah, gaar ahaan substrate-ka dalool ama kulul. [jinjichemical ]
- Wakhtiga furan ee la dheereeyey - waxay ku fiican tahay jeexjeexa aagga weyn, malaasta lakabka qaro weyn, ama xaaladaha ay tahay in tiirarka la hagaajiyo meelaynta ka dib. [hpmc ]
- Diidmada iyo iska caabinta sibidhka ka sii fiican - koollada dhumucdiisuna waxay si fiican u taageertaa tiirarka culculus waxayna ka hortagtaa ku-kufashada dusha sare. [celotech ]
Soo-saareyaasha agab-dhismaha, muuqalka sare ee HPMC ayaa inta badan ah doorashada ugu habboon marka waxqabadku ka miisaan badan yahay qiimaha: [hpmc ]
- Xabagta tile - darajooyinka viscosity 100,000-200,000 mPa·s waa wax caadi ah sababtoo ah waxay wanaajiyaan ku dheggan waxayna yareeyaan dhogorta saqafka ee wajiyada toosan. [kemoxcellulose ]
- balastarrada lakabka leh iyo nidaamyada dahaarka dibadda --muuqaalka sare ee HPMC wuxuu caawiyaa ilaalinta isku xirnaanta waxayna ka hortagtaa dildilaaca codsiyada dhumucda leh. [celotech ]
- Waxqabadka sare leh oo soo bandhiga hoobiyeyaal - halkaasoo waqti dheer oo furan iyo xoogga dammaanadda loo baahan yahay. [hpmc ]
Haddi aad samaynayso xabagyo tile ah oo culus ama dibeda waxay keenaysaa , muuqalka sare ee HPMC inta badan waa meesha ugu fiican.
Viscosity-hoose HPMC ma aha 'hooseeya' -waxaa lagu hagaajiyay socodka, simanaanta, iyo fudaydka isku dhafka : [kimachemical ]
- Shaqeyn fiican iyo codsi siman – koollada viscosity hoose way fududahay in la faafiyo lana dhammeeyo, gaar ahaan kuwa lakabka khafiifka ah ama kuwa jaakad khafiif ah leh. [hpmc ]
- Qoynta degdega ah iyo fuuq-celinta - hababka qallalan ee qallalan, mawduucyada hoose ee HPMC si dhakhso ah ayey u firdhisaa, yaraynaysaa kuuskuusan iyo hagaajinta bamka. [jilicsan ]
- Viscosity hoose ee qaabaynta isla qiyaasta - waxtar leh marka aad rabto inaad guud ahaan isku dhafka khafiifiso adigoo weli ka faa'iideysanaya xajinta biyaha. [pmc.ncbi.nlm.nih ]
Isticmaalka caadiga ah ee HPMC aragti-hoosaadka waxaa ka mid ah:kimachemical ]
- Jaakadaha skim iyo balastar-dhammaystir fiican - caadi ahaan 20,000-60,000 mPa·s oo loogu talagalay dusha siman, saxan-saaxiibtinimo ah. [hpmc ]
- Jidhka caadiga ah ee gidaarka iyo malaastarada gudaha - halkaas oo iska caabbinta aadka u daran ay aad uga muhimsan tahay dhammaystirka tayada iyo dabeecadda carrada. [jinjichemical ]
- Dahaarka wejiga dareeraha ah iyo qaabaynta la isku qurxiyo - waxyaalaha la isku qurxiyo iyo dawooyinka, darajooyinka viscosity hoose ayaa loo door bidaa alaab la buufin karo ama la shubi karo. [sayniskadirect ]
Haddi mudnaantaadu tahay dhammays siman, codsi fudud, iyo fuuq- , baxa yar-yar ee HPMC waxay inta badan keeni doontaa khibrad isticmaale oo ka wanaagsan.
Shaxda hoose ayaa soo koobaysa sida muuqalka sare ee HPMC iyo viscosity-hoose HPMC ay ugu kala duwan yihiin KPI-yada muhiimka ah ee khuseeya dhismaha iyo isqurxinta: [kemoxcellulose ]
| Hoyga | viscosity Sare ee HPMC (≥100,000 mPa·s) | Aragga hoose ee HPMC (<50,000 mPa·s) |
|---|---|---|
| Haysashada biyaha | Aad u fiican; Shabakadda polymer xooggan ayaa haysa biyo badan. (kemoxcellulose ) | Dhexdhexaad; ku filan lakabyo dhuuban iyo substrate-ka baahida hoose. (kimachemical ) |
| Sag iyo iska caabin simbiriirixan | Sare; ku habboon lakabyo qaro weyn iyo dhejis toosan. (celotech ) | Hoose; waxaa laga yaabaa inay u baahdaan waxyaabo kale oo lagu daro si loo helo taageero dufan culus. (kimachemical ) |
| Karti iyo hufnaan | Ka dhumuc weyn, adkaysi u leh faafitaanka; laga yaabaa inay dareemaan 'ka culus' gacanta. (kimachemical ) | Iska caabbinta dhogorta yaryar; Si sahlan loo tuman karo oo si habsami leh loo dhammeeyo. (kimachemical ) |
| Waqtiga furan | Ka dheer; waxay taageertaa hagaajinta fidsan iyo dib u dhigista. (kimachemical ) | Ka gaaban; si dhakhso ah maqaarka kor ugu kaca oo u dejiyo hababka qaarkood. (kimachemical ) |
| Socodka iyo bamgareynta | Hoos u dhig isla qiyaasta; laga yaabaa inay u baahdaan dhimista qiyaasta. (pmc.ncbi.nlm.nih ) | Socodka wanaagsan; ku habboon buufinta, lakabka khafiifka ah, iyo nidaamyada bamgareynta sare. (jilicsan ) |
| Kala duwanaanshaha dhismaha caadiga ah | 100,000-200,000 mPa·s (xabag-dhoobo, dhejisyo qaro weyn). (kimachemical ) | 40,000-60,000 mPa·s (jaakadaha dufanka leh, dhejiska fudud). (kimachemical ) |
Isbarbardhiggani wuxuu muujinayaa in muuqalka sare ee HPMC uu jecelyahay sii-haynta biyaha iyo iska caabbinta sagxada , halka maw-jilicda hoose ee HPMC ay door bidayso karti-shaqsiyeedka, simanaanta, iyo socodka . [kemoxcellulose ]
Kartida shaqada waxaa inta badan gacanta ku haysa viscosity koollada iyo walbahaarka soo saara : [pmc.ncbi.nlm.nih ]
- Viscosity High HPMC waxay kordhisaa walaaca dhalidda, markaa koollada 'wuxuu istaagaa' dheer oo aad bay ugu nugul tahay inuu ku dhaco, laakiin sidoo kale waxay dareemeysaa cufan waxayna u baahan kartaa dadaal dheeraad ah si ay u faafto.
- Viscosity-hooseeya HPMC waxay hoos u dhigtaa wax-soo-saarka walbahaarka, iyadoo siinaysa dheellitiran, dareere badan oo sahlan in la codsado lana dhammeeyo, laakiin waxaa laga yaabaa inay si qoto-dheer uga sii daadato dusha sare. [kimachemical ]
Ficil ahaan, naqshadeeyayaal badan ayaa doorta HPMC-viscosity-dhexdhexaad ah (50,000-100,000 mPa·s) si ay u tanaasulaan darbiga iyo balastarrada gudaha , dheellitirnaanta shaqada iyo iska caabinta sag. [jinjichemical ]
Iska caabbinta saggu waa awooda koollada cusub si ay uga hortagto qulqulka hoose ee culeyskeeda hoos yimaada, waxayna kuxirantahay: [celotech ]
- Cadaadiska wax-soo-saarka - darajooyinka viscosity-ga sarreeya waxay dhisaan walbahaarka dhalidda sare, ka hortagga socodka marka koollada ay nasato.
- Biyo-haynsiga --noolaanshaha hoose ee HPMC si dhakhso ah ayuu u engejin karaa, taasoo horseedda luminta isku-xidhnaanta hore iyo hoos u dhaca.
- Dareen-samaynta filimada - silsiladaha hydrofilic ee HPMC waxay sameeyaan filim joogto ah oo caawiya 'isku-qabsiga' adag. [zh.wikipedia ]
Dusha sare ee koollada toosan ama culeyska culeyska , leh ee HPMC (> 100,000 mPa·s) badanaa waa qasab; hooseeyo jaakadaha dhuuban ee khafiifka ah ee maqaarka , HPMC (20,000-60,000 mPa·s) ayaa badanaa ku filan. [kemoxcellulose ]
Halkii aad ku tiirsanaan lahayd noocyada guud, alaab-qeybiyeyaasha HPMC ee khibradda leh (sida Shandong Shengda ) waxay ku talinayaan borotokoolka imtixaanka afar-tallaabo si ay u kala doortaan darajooyinka viscosity-sare iyo kuwa hoose: [linkin ]
1. Qeex shuruudaha codsiga
- Ma koollo tile, darbi galiyay, jaakad jilicsan, ama qurxinta ? Mid kastaa wuxuu leeyahay baahiyo viscosity oo kala duwan. [hpmc ]
- Weydii: *Miyaan u baahanahay iska caabin sag-caabeedka ugu badan, simannaanta ugu badan, ama wakhtiga ugu badan ee furan?*
2. Dooro safafka hore ee viscosity
- Xabagta tiirarka iyo samaynta qaro weyn → ku bilow 100,000–200,000 mPa·s . [kimachemical ]
- Malaastarrada gidaarka iyo gudaha → waxay ku bilowdaan 50,000–100,000 mPa·s . [jinjichemical ]
- Jaakadaha skim, dhammayn wanaagsan, iyo waxyaalaha la isku qurxiyo → ku bilow 20,000–60,000 mPa·s . [hpmc ]
3. Samee tijaabooyinka shaybaarka dufcad yar
- Diyaari qaabab isku mid ah oo qallalan oo isku dhafan oo leh muuqaalo HPMC ah oo kala duwan laakiin isku qiyaas ah.
- Cabbir sii haysashada biyaha, iska caabbinta sag-caabeedka meelaha toosan, wakhtiga furan, iyo simannaanta dusha sare . [kimachemical ]
4. Hagaajin qiyaasta iyo viscosity
- Haddii saggu liito, kordhi viscosity ama in yar kordhiso qiyaasta HPMC.
- Haddii karti-shaqsiyeedku aad u adag tahay, yaree qiyaasta HPMC ama u beddel heerka viscosity hoose . [jinjichemical ]
Markaad raacdo socodka shaqadan, waxaad iska ilaalisaa labadaba injineernimada (adoo isticmaalaya 200,000 mPa·s halkaas oo 80,000 mPa·s ay ku filan tahay) iyo hawlqabad la'aan (adoo isticmaalaya 40,000 mPa·s ee hababka culus).
Gobollada leh heerkul sare iyo qoyaan hooseeya, substrate-ka dhaqsaha leh ayaa biyaha ka tuujiya hoobiyeyaal, yareynaya wakhtiga furan waxayna yareynayaan xoogga curaarta.
- Hormoodka soo saaraha tile-dhesive ee Bariga Dhexe wuxuu ka beddelay viscosity HPMC (40,000 mPa·s) una beddelay HPMC-muuqaalka sare (150,000 mPa·s) wuxuuna soo sheegay: [kemoxcellulose ]
- + 30% waqti dheer oo furan
- Dusha sare ee la dhimay 22%
- Ku dheggan oo ka sii wanaagsan oo ku dul dhejisan tiirarka nuugista sare
Aragtida furaha ah: muuqalka sare ee HPMC waxa uu magdhabaa xaaladaha adag ee deegaanka iyada oo hagaajinaysa sii haynta biyaha iyo xasiloonida qaabdhismeedka. [jinjichemical ]
Qandaraasle-dhammeedka gudaha Yurub wuxuu u baahday jaakad jilicsan oo jilicsan oo loogu talagalay mashaariicda deegaanka ee dhamaadka-sare.
-Waxay qaateen HPMC muuqaal yar (40,000 mPa·s) oo leh qiyaas waxyar ka sarreeya waxayna gaadheen: [hpmc ]
- Xawaaraha codsiga oo aad u dheereeya
- Dhammays heersare ah oo siman oo leh ciid yar
- Viscosity hoose ee qasiyaha, hagaajinta bamka
Xaaladdan oo kale, viscosity hooseeyo HPMC waxay keentay dheelitirka ugu fiican ee karti-shaqsiyeedka iyo tayada dhammayn , in kasta oo iska caabbinta saggu ay aad uga yar tahay darbiyada gudaha. [kimachemical ]
Tusaalooyinkani waxay muujinayaan in aanu jirin wax caalami ah oo 'ugu wanaagsan' ; doorashada saxda ah waxay ku xiran tahay codsiga, deegaanka, iyo substrate.
Sida soo saaraha HPMC ee Shiinaha ku salaysan oo leh muuqaal muuqaal buuxa laga bilaabo 400mPa·s ilaa 200,000 mPa·s Shandong Shengda Qalabka Cusub , Co., Ltd. ee linkin ]
- Darajooyinka viscosity-ka gaarka ah - waxaan ku halayn karnaa HPMC ilaa heerar gaar ah (tusaale, 80,000 mPa·s ee darbiga dhuuban ama 180,000 mPa·s ee foornada wax-qabadka sare leh).
- La-talin gaar ah oo codsi ah - kooxdayada farsamadu waxay gacan ka geysan kartaa doorashada inta u dhaxaysa HPMC-ga-muuqaalka sarreeya iyo HPMC-muuqaalka hoose ee ku salaysan naqshadaynta isku dhafka ah, cimilada, iyo substrate-kaaga.
- Xakamaynta tayada - Badeecadahayada HPMC waxay maraan viscosity, hydroxypropyl content, iyo tijaabinta haynta biyaha si loo hubiyo waxqabadka joogtada ah. [linkin ]
Markaad la wadaagto alaab-qeybiye HPMC ah oo khibrad leh, waxaad heli kartaa ma aha oo kaliya alaabta ceeriin, laakiin waxaad heleysaa kor u qaadida viscosity-ka ee codsiga.
Haddi aad horumarinayso xabagta tile-ka, budo-shubka, ama habaynta qurxinta , viscosity saxda ah ee HPMC waxa uu si wayn u wanaajin karaa waxqabadka iyo khibrada isticmaale.
Tallaabada ficil:
La xidhiidh Shandong Shengda New Material Co., Ltd. si aad u heshid talo ku saabsan viscosity caadadii codsigaaga gaarka ah, oo ay ku jiraan muunad muunad bilaash ah iyo hagitaan farsamo oo ku saabsan isu dheellitirnaanta kartida iyo iska caabinta sag . [linkin ]
Viscosity High-viscosity HPMC (> 100,000 mPa·s) waxay bixisaa haynta biyaha sare, waqti dheer oo furan, iyo iska caabbinta sag/sibxabsi fiican, halka HPMC-ga yar ee viscosity (<50,000 mPa·s) ay bixiso socodka wanaagsan, dhammays fudud, iyo codsi sahlan. [kemoxcellulose ]
Inta badan xabagta tile-ku waxay isticmaalaan HPMC-muuqaalka sare ee 100,000-200,000 mPa·s si ay u kordhiyaan ku dheggan iyo iska caabbinta silbashada ee dusha toosan. [kemoxcellulose ]
Haa, viscosity-hoose ama dhexdhexaad HPMC (20,000-100,000 mPa·s) ayaa si weyn loogu isticmaalaa galka gidaarka, iyada oo viscosity la doortay si loo miisaamo sinnaanta iyo sag-yaraanta. [jinjichemical ]
Viscosity sare HPMC guud ahaan waxa ay keentaa haynta biyaha ka wanaagsan sababtoo ah shabakadeeda polymer dhumucdeedu waxay haysaa biyo badan waxayna hoos u dhigtaa qalajinta. [jinjichemical ]
Haa; qaabab badan oo horumarsan ayaa isku daraya laba muuqasho si loo habeeyo rheology, caabbinta sagxada, iyo kartida shaqada, laakiin shaybaadhka shaybaadhka ayaa lama huraan u ah kor u qaadista qiyaasta iyo waxqabadka. [kimachemical ]
