Lipotso tse botsoang khafetsa mabapi le HPMC

Re nka botšepehi le win-win e le molao-motheo oa ts'ebetso, 'me re tšoara khoebo e' ngoe le e 'ngoe ka taolo le tlhokomelo e tiileng.

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.

Matla a khoheli a khethehileng: ha matla a khoheli a itseng a le kholoanyane, a boima ho feta, a betere. Ka kakaretso, ke hobane litaba tsa hydroxypropyl ho eona li phahame. Haeba litaba tsa hydroxypropyl li phahame, ho boloka metsi ho molemo.

Mekhoa ea ho qhibiliha ea hydroxypropyl methyl cellulose ke efe?

Mefuta eohle e ka kenyelletsoa ho lisebelisoa ka mokhoa o omileng oa ho kopanya;

Ha e hloka ho kenngoa ka ho toba ho tharollo ea metsi ka mocheso oa kamore, ho molemo ho sebelisa mofuta oa ho hasana ha metsi a batang. Ka kakaretso, e ka tšelisoa ka hare ho metsotso e 10-90 ka mor'a ho eketsa (ho hlohlelletsa)

Mehlala e tloaelehileng e ka qhibiliha ka mor'a ho kopanya le ho qhalakanngoa ka metsi a chesang, ho eketsa metsi a batang, ho hlohlelletsa le ho pholile;

Haeba caking le ho phuthela ho etsahala nakong ea ho qhibiliha, ke ka lebaka la ho kopanya ho sa lekaneng kapa mehlala e tloaelehileng e kenngoa ka ho toba metsing a batang. Ka nako ena, e lokela ho tsosoa ka potlako.

Haeba li-bubble li hlahisoa nakong ea ho qhibiliha, li ka tlosoa ka ho ema lihora tse 2-12 (nako e tobileng e itšetlehile ka ho tsitsa ha tharollo), vacuuming, pressurizing le mekhoa e meng, kapa ho eketsa tekanyo e nepahetseng ea defoamer.

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.

Haeba u senya lera le leng karolong e ka tlaase pele le omella, ho boetse ho bonolo ho senya.
