IHydroxypropyl methyl cellulose ether yodaka olomile oluxubile oluxubile

Odakeni oluxubile oluxubile oluxubile, okuqukethwe kwe-HPMCE kuphansi kakhulu, kodwa kungathuthukisa ukusebenza kodaka olumanzi. Ukukhetha okunengqondo kwe-cellulose ether enezinhlobonhlobo ezihlukene, i-viscosity ehlukene, ubukhulu bezinhlayiyana ezihlukene, idigri ye-viscosity ehlukene kanye nenani lokwengeza kunethonya ekusebenzeni kodaka olomile. Njengamanje, ukusebenza okuningi kokugcinwa kwamanzi okwakhiwa kwamatshe nodaka lokunamathisela akukuhle, imizuzu embalwa kuzovela ukuhlukaniswa okuncane kodaka lwamanzi amile. Ukugcinwa kwamanzi kuyimpahla ebalulekile ye-Methyl cellulose ether, ephinde ikhathazwe ngabakhiqizi abaningi bodaka olomile e-China, ikakhulukazi eningizimu lapho izinga lokushisa liphezulu. Izici ezithinta ukugcinwa kwamanzi kodaka olomile zifaka inani le-cellulose ether HPMC, i-viscosity ye-cellulose ether HPMC, ukucoleka kwezinhlayiya kanye nezinga lokushisa lendawo ezungezile. I-Cellulose ether iwuhlobo lwe-polymer yokwenziwa eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. I-cellulose ether encibilikayo emanzini idlala indima ebalulekile odakeni ezicini ezintathu, enye iwumthamo omuhle kakhulu wokubamba amanzi, enye ithonya lokungaguquguquki kodaka kanye ne-thixotropy, kanti okwesithathu ukuxhumana nosimende. Umsebenzi wokugcina amanzi we-cellulose ether uncike ekumunceni kwamanzi kwesisekelo, ukwakheka kodaka, ukujiya kodaka, isidingo samanzi sodaka kanye nesikhathi sokusetha sento yokumisa. Ukugcinwa kwamanzi kwe-cellulose ether ngokwayo kuvela ekuncibilikeni nasekuphelelweni kwamanzi emzimbeni kwe-cellulose ether ngokwayo.
