Waba uzi hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose ikoreshwa cyane mubikorwa byubwubatsi. Uyu munsi, nzamenyekanisha uburyo bwo gusesa hydroxypropyl methylcellulose nuburyo bwo gusuzuma ubwiza bwa hydroxypropyl methylcellulose.

Uburyo bwo gushonga hydroxypropyl methylcellulose:

Moderi zose zirashobora kongerwaho ibikoresho mukuvanga byumye;

Iyo bikenewe kongerwaho muburyo butaziguye ubushyuhe busanzwe bwamazi, nibyiza gukoresha ubwoko bukwirakwiza amazi akonje, kandi burashobora kubyimba muminota 10-90 nyuma yo kongeramo;

Nyuma yo gukurura no gukwirakwiza n'amazi ashyushye kubwoko busanzwe, ongeramo amazi akonje hanyuma ukangure kuyashonga;

Niba hari agglomeration hamwe na coating mugihe cyo gusesa, biterwa no gukurura bidahagije cyangwa kongeramo amazi akonje kumwirondoro usanzwe. Muri iki gihe, bigomba gukangurwa vuba;

Niba ibibyimba byabyaye mugihe cyo guseswa, birashobora gusigara bihagaze kumasaha 2-12 (bigenwa ukurikije igisubizo kiboneye) cyangwa bigakurwaho na evacuya, igitutu, nibindi, kandi umubare wabyo wa defoamer urashobora kandi kongerwamo.

Nigute ushobora kumenya ubuziranenge bwa hydroxypropyl methylcellulose byoroshye kandi byihuse

Kwera: Ukurikije umweru, ntibishoboka kumenya niba HPMC ishobora gukoreshwa bisanzwe, kandi niba imiti yera yongewemo mubikorwa, bizagira ingaruka no ku bwiza bwayo. Nyamara, ibicuruzwa bifite umweru mwiza nibyiza cyane.

Ubwiza: HPMC muri rusange ni mesh 80, mesh 100, mesh 120, nibyiza nibyiza.

Kwimura: shyira HPMC mumazi kugirango ube colloid ibonerana, kandi urebe uko ikwirakwizwa. Iyo itumanaho ryinshi, ibintu bitangirika mumazi. Mubisanzwe, ihererekanyabubasha nibyiza mumashanyarazi ahagaritse na reaction ya horizontal. Nibibi muri reaction ya vertical, ariko ntishobora gusobanura ko ubwiza bwibicuruzwa byakozwe na reaction ya vertical ari byiza kuruta ibya reaction ya horizontal.

Uburemere bwihariye: Muri rusange, kubera hydroxypropyl nyinshi, ingaruka zo gufata amazi ni nziza.
