Uyayazi i-hydroxypropyll methylcellulose?

I-Hydroxypropyll methylcellulose isetshenziswa kabanzi embonini yezokwakha. Namuhla, ngizokwethula indlela yokuchithwa kwe-hydroxypropylllylylylk kanye nokuthi ungahlulela kanjani ikhwalithi ye-hydroxypropyllylylylyllose.

Indlela yokuqeda i-hydroxypropyllylyly methylcellulose

Wonke amamodeli angangezwa kokuqukethwe ngokuxuba owomile;

Lapho idinga ukungezwa ngqo kwisisombululo esijwayelekile samanzi samanzi okushisa, kungcono ukusebenzisa uhlobo lokuhlakazeka kwamanzi okubandayo, futhi kungakhula kungakapheli imizuzu eyi-10-90 ngemuva kokungeza;

Ngemuva kokuvusa nokusabalalisa ngamanzi ashisayo ngohlobo olujwayelekile, engeza amanzi abandayo futhi uvuse ukuwuqeda;

Uma kukhona i-agglomeration kanye ne-coating ngesikhathi sokuchithwa, kubangelwa ukuvuselelwa okunganele noma ukukwengeza kwamanzi abandayo kumaphrofayili ajwayelekile. Ngalesi sikhathi, kufanele kuvuswe ngokushesha;

Uma ama-bubble akhiqizwa ngesikhathi sokuchithwa, angashiywa ukuze ame amahora angama-2-16 (azimisele ngokuya ngokuvumelana kwesixazululo) noma asuswe ngokuphuma, ukucindezelwa, bese kufakwa inani elifanele le-defoamer.

Ungawahlulela kanjani ikhwalithi ye-hydroxypropylllm methylcellulose kalula nangokuqondile

IMhlophe: Ngokusho kobumsulwa, akunakwenzeka ukuthola ukuthi i-HPMC ingasetshenziswa ngokujwayelekile, futhi uma ngabe ama-anchents anwebiwe angezwe kwinqubo yokukhiqiza, kuzothinta futhi ikhwalithi yayo. Kodwa-ke, imikhiqizo enobuthi obuhle kakhulu ilungile kakhulu.

I-FINGness: I-HPMC imvamisa i-80 Mesh, 100 Mesh, 120 Mesh, the Phenne the Phecter the Engcono.

I-Transmitance: Beka i-HPMC emanzini ukuze wakhe i-colloid esobala, bese ubheka ukudluliselwa kwayo. Lapho kukhudlwana okudluliselwa, izinto ezingenakufakwa ngaphansi emanzini. Ngokuvamile, ukudluliselwa kungcono kuma-reactors mpo nasezimpendweni ezivundlile. Kubi kakhulu ku-reactical mpo, kepha akunakuchaza ukuthi ikhwalithi yomkhiqizo ekhiqizwa yi-reactoror mpo ingcono kunaleyo yokuphendula okuvundlile.

Amandla adonsela phansi athile: Ngokuvamile, ngenxa yokuqukethwe okuphezulu kwe-hydroxypropyl, umphumela wokugcina amanzi ulungile.
