Hydroxypropyl methyl cellulose e arotsoe ka mefuta e mengata, 'me phapang ke efe tšebelisong ea eona?
HPMC e ka aroloa ka mefuta ea hang-hang le e chesang e qhibilihang.Lihlahisoa tsa hang-hang li hasana ka potlako metsing a batang ebe li nyamela ka metsing.Ka nako ena, mokelikeli ha o na viscosity, hobane HPMC e qhalakanngoa ka metsing 'me ha e hlile ha e qhibilihe.Kamora metsotso e ka bang 2 (ho hlohlelletsa), viscosity ea mokelikeli e eketseha butle-butle, e etsa "viscous colloid" e hlakileng e hlakileng.Lihlahisoa tse chesang tse qhibilihang li ka hasana ka potlako metsing a chesang 'me tsa nyamela metsing a chesang ha li kopane metsing a batang.Ha mocheso o theohela mocheso o itseng (ho ea ka mocheso oa gel oa sehlahisoa), viscosity e hlaha butle-butle ho fihlela ho thehoa colloid e hlakileng ea viscous.
U ka ahlola joang boleng ba hydroxypropyl methyl cellulose habonolo le ka mokhoa o hlakileng?
Bosoeu.Le hoja bosoeu bo ke ke ba tseba hore na HPMC e bonolo ho e sebelisa, 'me haeba li-whitening agents li kenngoa ts'ebetsong ea tlhahiso, li tla ama boleng ba tsona, lihlahisoa tse ngata tse ntle li na le bosoeu bo botle.
Bokhabane: botle ba HPMC hangata ke 80 mesh le 100 mesh, le 120 mesh e nyane.Ha botle bo le botle, bo betere.
Ho fetisa leseli: ka mor'a hore HPMC e kenngoe ka metsing ho etsa colloid e bonaletsang, sheba phetiso ea eona ea leseli.Ha leseli le fetisa ka bongata, ho ba betere.Ho bolela hore ho na le lintho tse fokolang tse sa tsitsang ho eona.Phetisetso ea reactor e otlolohileng hangata e ntle, 'me ea reactor e tšekaletseng e mpe le ho feta.Leha ho le joalo, ha ho bolele hore boleng ba reactor e emeng e betere ho feta ea reactor e tšekaletseng.Ho na le lintlha tse ngata tse khethollang boleng ba sehlahisoa.

Ke karolo efe eo hydroxypropyl methyl cellulose e nang le eona ts'ebetsong ea putty powder, le hore na ho na le k'hemistri?
Ka phofo ea putty, e phetha likarolo tse tharo: ho tiisa, ho boloka metsi le ho haha.Ho teteana, selulose e ka ba motenya, ea bapala karolo ea ho fanyeha, ea boloka seaparo sa tharollo holimo le tlase, 'me se hana ho theoha.Ho boloka metsi: etsa hore phofo ea putty e ome butle, 'me u thuse lime calcium ho arabela tlas'a ketso ea metsi.Kaho: selulose e na le phello ea lubricating, e ka etsang hore putty powder e be le ts'ebetso e ntle ea ho sebetsa.HPMC ha e nke karolo ho karabelo efe kapa efe ea lik'hemik'hale, empa e bapala karolo ea tlatsetso feela.
Mocheso oa gel oa hydroxypropyl methyl cellulose o amana le eng?
Thempereichara ea gel ea HPMC e amana le litaba tsa eona tsa methoxyl.Ha maemo a methoxyl a le tlase, mocheso oa gel o phahame.
na ho na le kamano pakeng tsa ho theoha ha putty powder le hydroxypropyl methyl cellulose?
Ho bohlokoa!!!HPMC e na le ho boloka metsi a fokolang, e leng se tla baka tahlehelo ea phofo.
Tšebeliso ea hydroxypropyl methyl cellulose ka putty powder, lebaka la li-bubble ka putty powder ke lefe?
HPMC e bapala likarolo tse tharo ho putty powder: ho teteaneng, ho boloka metsi le ho haha.Mabaka a li-bubble ke a latelang:
Ho eketsoa metsi a mangata haholo.
