ManjeI-Hydroxypropyl carboxymethyl celluloseImakethe yokuthengisa ngokwengeziwe, intengo ayilinganiseli, ukuthi ungasusa kanjani ngokushesha ikhwalithi ye-hydroxypropyllllylylylylylylylylylylylylylylylylylylylylyllopylylylylylylylylys methyl cellulose sekuyinkinga ebalulekile! Ngakho-ke ukuthi ungahlulela kanjani ikhwalithi ye-hydroxypropyll methylcellulose? Into yokuqala okufanele uyibheke i-Hydroxypropyllylls; Yize ubumsulwa bungacaci ukuthi ngabe i-HPMC ilungele uhlelo lokusebenza, kepha inqubo yokucubungula kukhona nabakhiqizi ababi bazokwengeza i-ejenti yamhlophe, kuzolimaza ikhwalithi yayo. Kepha ngokuvamile ekhuluma, iningi le-cellulose ether enhle kakhulu limhlophe.
Okwesibili, ukubona ubumsulwa be-hydroxypropylllylyll methyllulose: I-Hydroxypropyl carboxyyl cellulose usayizi wezinhlayiyana eziyizinhlayiyana eziyizinhlayiyana ezingama-80-100, i-hydroxyyethyl cellulose HECHMC ecishe ibe yi-100 mesh. I-HPMC ye-mesh engu-60-80, i-General Methyl cellulose softer, ukusakazwa okungcono.
Isixazululo se-cellulose ether clarity:I-HPMCFaka emanzini ukukhiqiza isixazululo se-colloid esobala, bheka esiphakeme isixazululo, ukukhulisa isisombululo, lokho akunciphisi into yamakhemikhali iphansi.
Lapho impahla ifudumele, i-lelatincin yafakwa noma yahlanganiswa futhi yakhunjulwa kamuva. Kungama-hydrophobic kanye namanzi. Ukhonkolo uyisibopho esisemqoka kanye ne-densalfication eluhlaza impahla evumayo yamanzi kaPutty Putty. Umgomo wayo omelana namanzi umi kangangokuba: Ngenqubo yokungeza amanzi futhi uvuse i-latex evuselelayo ye-latex kanye nosimende, i-towx ye-latex iqhubeka ibuyela kwifomu lokuqala le-emulsion, futhi izinhlayiya ze-latex zisatshalaliswa ngokulinganayo ku-caste cent. Ngemuva kokuthi usimende uhlangabezana namanzi, ukusabela kwe-hydration kuqala, futhi isixazululo se-CA (oh) sifinyelela ku-satural futhi sakhiwe amakristalu, futhi ngasikhathi sinye, amakristalu e-calcinium silarte colloids akhiqizwa. Izinhlayiya ze-latex zifakwa kwizinhlayiya ze-gel kanye ne-inviddrated cent. Ngenqubekela phambili yokusabela kwe-hydration, imikhiqizo ye-hydration iyanda, futhi izinhlayiya ze-latex kancane kancane ziqoqelwa ku-void yezinto ezibonakalayo ezinjengesimende, futhi zakha ungqimba olusondele kakhulu ngaphezulu kwejeli yesimende. Ngenxa yokuncishiswa kancane kancane kwamanzi owomile, izinhlayiya ezihlanganiswe ngokuqinile ezibuyiselwe ama-latex ama-latex kanye nama-voids aqede ukwakha ifilimu eqhubekayo, ebeka ingxube kasimende unamathisele i-matrix yokuhlangana, nokubopha unamanzi ahlanganisiwe nezinye izihlanganisi zensimbi.
