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 konakalaI-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.IHydroxypropyl 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 yamakhemikhali yansuku zonke.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.
IHydroxypropylmethylcellulose ingasetshenziselwa ukuxuba izinto zokwakha nezakhiwo, futhi amafomula okuxuba okomile angaxubana ngokushesha namanzi ukuze athole ukuvumelana okudingekile.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.Ingase futhi ithuthukise ukubukeka komkhiqizo futhi ithuthukise ukumelana nokugoqa kwe-adhesive tile ye-ceramic.
