Hydroxypropyl methylcellulose, eo hape e tsejoang e le HPMC, ke nonionic cellulose ether e fumanoang ho tloha k'hothone e hloekisitsoeng, thepa ea tlhaho ea polymer, ka letoto la mekhoa ea lik'hemik'hale. Ke phofo e tšoeu kapa e mosehla hanyane e qhibilihang habonolo metsing. Ha re bue ka mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose.
1. Hydroxypropyl methylcellulose e sebelisoa haholo-holo e le tlatsetso bakeng sa putty powder, seretse le sekhomaretsi. E kenyellelitsoe ho seretse sa samente, e ka sebelisoa e le moemeli oa ho boloka metsi le ho thibela ho eketsa pompo; e kenyellelitsoe ho putty powder le glue, e ka sebelisoa e le setlamo. E le ho ntlafatsa ho ata le ho atolosa nako ea ts'ebetso, re nka Qingquan Cellulose e le mohlala ho hlalosa mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose.
2. Hydroxypropyl methylcellulose e tloaelehileng e qala ho tsosoa le ho qhalakanngoa ka metsi a chesang, ebe e kenngoa ka metsi a batang, a hlohlelletsa le ho pholile ho qhibiliha;
Ka ho khetheha: nka 1/5-1/3 ea palo e hlokahalang ea metsi a chesang, hlohlelletsa ho fihlela sehlahisoa se ekelitsoeng se ruruha ka ho feletseng, ebe u eketsa karolo e setseng ea metsi a chesang, e ka ba metsi a batang kapa esita le metsi a leqhoa, 'me u hlohlelletse ho mocheso o loketseng (10°C) ho fihlela o qhibiliha ka ho feletseng.
3. Mokhoa oa ho kolobisa ka motsoako oa motsoako:
Hlakola hydroxypropyl methylcellulose ka har'a motsoako oa lintho tse phelang kapa u e kolobise ka motsoako oa tlhaho, ebe u eketsa kapa u eketsa metsi a batang ho e qhaqha hantle. The solvent organic e ka ba ethanol, ethylene glycol, joalo-joalo.
4. Haeba agglomeration kapa wrapping e etsahala nakong ea ho qhibiliha, ke hobane ho tsosoa ha hoa lekana kapa mohlala o tloaelehileng o kenngoa ka ho toba metsing a batang. Mothating ona, tsosa ka potlako.
5. Haeba li-bubble li hlahisoa nakong ea ho qhibiliha, li ka siuoa lihora tse 2-12 (nako e tobileng e itšetlehile ka ho lumellana ha tharollo) kapa ho tlosoa ka vacuuming, khatello ea maikutlo, joalo-joalo, kapa ho eketsa palo e loketseng ea moemeli oa defoaming.
Mehato ya tlhokomelo
Hydroxypropyl methylcellulose e arotsoe ka mefuta e qhibilihang butle le e qhibilihang hang-hang. Instant hydroxypropyl methylcellulose e ka qhibiliha ka kotloloho metsing a batang.
