I-hypromellose ehlanzekileI-HPMCiyabonakala i-fluffy futhi inenqwaba encane yenqwaba esukela ku-0.3 kuya ku-0.4 ml, kuyilapho i-HPMC ephihliwe ihamba kakhulu, iyasinda futhi ihlukile kumkhiqizo wangempela ngokubukeka. Isixazululo samanzi esihlanzekile se-hypromellose HPMC sicacile futhi sinokudluliswa kokukhanya okuphezulu, futhi izinga laso lokugcinwa kwamanzi lingaphansi kuka-97% , kuyilapho isixazululo samanzi se-HPMC esihlanganisiwe sinodaka, futhi izinga lokugcinwa kwamanzi alikwazi ukufinyelela ku-80%. OkumsulwaI-Hypromellose HPMCakufanele ihogele i-ammonia, isitashi notshwala, ngenkathi iphingiweI-HPMCijwayele ukuhogela iphunga elihlukahlukene futhi izwakale isindayo. Izimpushana ezihlanzekile ze-hypromellose HPMC ziyi-fibrous ngaphansi kwengilazi ekhulisayo, kuyilapho izimpushana ze-HPMC ezixutshiwe zingama-granular solids noma amakristalu.
IHydroxypropylmethylcellulose iyisengezo sezinto zokwakha ezivamile lapho kusetshenziswa izinto zokwakha, ezisetshenziswa kakhulu embonini nasezinhlobonhlobo eziningi. I-Hydroxypropyl methyl cellulose ingahlukaniswa ibe uhlobo olusheshayo lwamanzi abandayo kanye nohlobo oluncibilikayo olushisayo.
I-HPMC encibilikayo emanzini abandayo ingasetshenziselwa i-putty powder, udaka, iglue ewuketshezi, okokunamathela okuwuketshezi, kanye nemikhiqizo yansuku zonke yamakhemikhali. I-Hot Melt HPMC ivamise ukusetshenziselwa imikhiqizo yempushana eyomile futhi ixutshwa ngokuqondile nempushana eyomile ukuze ifakwe umfaniswano, njengempushana efaka udaka nodaka. IHydroxypropylmethylcellulose ingasetshenziswa kabanzi ukuthuthukisa ukusebenza kwezinto zokwakha ezinama-hydrate ezifana usimende negypsum. Odakeni olusekelwe kusimende, ukugcinwa kwamanzi kungathuthukiswa, isikhathi sokulinganisa nesikhathi sokuvula singanwetshwa, futhi ukumiswa kokugeleza kungancishiswa.
I-Hydroxypropylmethylcellulose ingasetshenziselwa ukuxuba izinto zokwakha nezakhiwo, futhi amafomula okuxuba okomile angaxubana ngokushesha namanzi ukuze athole ukungaguquguquki okudingekayo. I-cellulose ether incibilika ngokushesha futhi ayibumbi. I-Methylcellulose ingaxutshwa nempushana eyomile yezinto zokwakha. Inezici zokuhlakazeka kwamanzi abandayo, futhi ingenza ingxube ibe ntekenteke kakhulu ngisho nezinhlayiya eziqinile ezimisiwe. Ngaphezu kwalokho, ingathuthukisa i-lubricity ne-plasticity, ikhulise ukucutshungulwa, futhi yenze ukwakhiwa komkhiqizo kube lula kakhulu. Ukugcinwa kwamanzi okuthuthukisiwe kanye namahora okusebenza amade kusiza ukuvimbela ukugeleza okuqondile kodaka namathayili, kunwebe isikhathi sokupholisa, futhi kuthuthukise ukusebenza kahle komsebenzi.
I-Hydroxypropylmethylcellulose ingathuthukisa amandla okubopha ama-adhesive tile e-ceramic, ithuthukise ukumelana nokuqhekeka kodaka kanye namalunga okhuni, ingakhulisi kuphela okuqukethwe komoya odakeni, kodwa futhi inciphise kakhulu amathuba okuqhekeka. Kungase futhi kuthuthukise ukubukeka komkhiqizo futhi kuthuthukise ukumelana nokugoqa kwe-adhesive tile ye-ceramic.
