Inqobo nje uma inani elifanele le-cellulose ether HPMC yezinga lokudla lengezwa ekudleni okuthosiwe, ukuthathwa kwamafutha enqubweni yokuthosa kungancishiswa kakhulu, inani eliphelele likawoyela wokudla okuthosiwe lingancishiswa, kanye nokunambitheka komkhiqizo othosiwe. ingathuthukiswa, umjikelezo wokushintsha amafutha wokudla okuthosiwe ungandiswa, isivuno somkhiqizo othosiwe singandiswa futhi izindleko zamafutha zingancishiswa.
Ukudla okuthosiwe kuthandwa kakhulu ngumphakathi ngenxa yokunambitheka kwakho okuyingqayizivele. Nokho, ekudleni kwanamuhla okwandayo okunempilo, ukudla okuthosiwe okunamafutha aphezulu nakho kwenza abathengi baxwaye.
Yiqiniso, ekusetshenzisweni okuqondile kwezithako zokudla ze-cellulose ether ngayinye zingakwazi ukufeza umsebenzi owodwa kuphela, isibonelo, i-methylcellulose yebanga lokudla (MC) ne-hydroxypropyl methylcellulose (HPMC) inganciphisa ngokuphumelelayo okuqukethwe kwamafutha okudla okuthosiwe; I-carboxymethyl cellulose (CMC) yebanga lokudla, esetshenziselwa imikhiqizo yobisi, ingathuthukisa ukunambitheka futhi ithuthukise ukuzinza kwamaprotheni, asetshenziselwa inqubo yokubhaka, ingalawula ngokuphumelelayo okuqukethwe kwamanzi enhlama; I-hydroxypropyl cellulose yezinga lokudla (HPC) inganciphisa ngempumelelo inani likakhilimu wemvelo kufomula, kuyilapho igcina ukunambitheka okubushelelezi nokuthambile, futhi ibone umqondo wokusetshenziswa kokudla okunempilo.
I-cellulose ether derivatives isetshenziswe kabanzi embonini yokudla isikhathi eside. Ukuguqulwa ngokomzimba kwe-cellulose kungalawula izakhiwo ze-rheological, i-hydration kanye nezakhiwo ze-microstructure zohlelo. Imisebenzi emihlanu ebalulekile ye-cellulose eguquliwe ngamakhemikhali ekudleni i-rheology, i-emulsification, ukuqina kwegwebu, ikhono lokulawula ukwakheka nokukhula kwekristalu yeqhwa, kanye nokubopha amanzi.
Siza ubuchwepheshe benyama yokwenziwa emhlabeni jikelele obungaphezu kwama-20 ukwenza ukwesekwa kwezobuchwepheshe. Ukufakwa kuhlu kwemakethe yesitoko kuhloswe kakhulu ekuthandeni kwaseMelika naseYurophu. Umqondo ungowokujwayela i-capsule yezitshalo, iqembu lixhumane. Ngekota yokuqala yangonyaka odlule, benze inguqulo mbumbulu yenyama yokwenziwa. Sizama ukushintsha ekukhiqizeni i-vector elabhorethri. Njengamanje, inyama yokwenziwa yaphesheya kwezilwandle ingu-140-150,000 yuan/ton, kodwa izindleko ziphansi. Inkampani izokwenza imali nge-cellulosic ether kuqala, futhi ikhathazeke ngemali yenyama yokwenziwa kamuva. Ingxenye enzima kakhulu yenyama yokwenziwa i-cellulose, futhi i-DuPont cellulose ether iyindawo yokunamathela. Le nkampani idayisa amathani angu-70,000 kuya kwangu-80,000, futhi ino-60% wemali engenayo. Imishini yakamuva nethuthuke kakhulu, okokusebenza kwe-Dow's kanye ne-Shin-etsu ineminyaka engama-20 noma engu-20 ubudala, ithengwe kumnikezeli wemishini eJalimane. Ifomula eyinhloko yenyama yokwenziwa ibalulekile.
