Namuhla sizogxila endleleni yokwengeza izinhlobo ezithile zezithina. Izinhlobo zezithina ezivame ukusetshenziswa kakhulu yi-inorganic, i-cellulose, i-acrylic, kanye ne-polyurethane. Izinto ezingaphili ngokuyinhloko yi-bentonite, i-fumed silicon, njll., ezivame ukungezwa ku-slurry ukuze zigaywe, ngoba ...Funda kabanzi»

Mayelana ne-Cellulose I-Cellulose iyi-polysaccharide enkulu eyakhiwe yi-glucose. Itholakala ngobuningi ezitshalweni eziluhlaza nasezintweni eziphilayo zasolwandle. Iyinto yemvelo esakazwa kabanzi futhi enkulu kunazo zonke emvelweni. Ihambisana kahle nezinto eziphilayo, ivuseleleka futhi iyabola futhi...Funda kabanzi»

I-cellulose ether yenziwe nge-cellulose ngokusebenzisa ukusabela kwe-etherification kwe-ether eyodwa noma eziningana ze-etherification kanye nokugaya okomile. Ngokwezakhiwo zamakhemikhali ezahlukene ze-ether substituents, ama-cellulose ethers angahlukaniswa abe ama-anionic, ama-cationic kanye nama-nonionic ethers. Ionic cellulose et...Funda kabanzi»

Ngokusho kombiko wakamuva ovela ku-IHS Markit, ukusetshenziswa komhlaba wonke kwe-cellulose ether—i-polymer encibilika emanzini ekhiqizwa ukuguqulwa kwamakhemikhali kwe-cellulose—kucishe kube ngamathani ayizigidi eziyi-1.1 ngo-2018. Kuwo wonke umkhiqizo we-cellulose ether womhlaba wonke ngo-2018, ama-43% avela e-Asia (iShayina yayine-79...Funda kabanzi»

1) Ukusetshenziswa okuyinhloko kwe-ether ye-cellulose yebanga lokudla. I-Cellulose ether iyisengezo sokuphepha kokudla esaziwayo, esingasetshenziswa njengesithambisi sokudla, isiqinisi kanye nesikhuthazi ukuze siqine, sigcine amanzi, sithuthukise ukunambitheka, njll. Sisetshenziswa kabanzi emazweni athuthukile, ikakhulukazi ekudleni okubhakiwe, i-fiber Vegetari...Funda kabanzi»

Kusetshenziswa i-cellulose njengezinto zokusetshenziswa, i-CMC-Na yalungiswa ngendlela enezinyathelo ezimbili. Eyokuqala inqubo ye-alkaliization ye-cellulose. I-cellulose isabela ne-sodium hydroxide ukuze ikhiqize i-alkali cellulose, bese i-alkali cellulose isabela ne-chloroacetic acid ukuze ikhiqize i-CMC-Na, ebizwa ngokuthi i-e...Funda kabanzi»
