Tshebetso ea Ts'ebeliso ea HPMC
Hydroxypropyl methyl cellulose (HPMC) ke mofuta oa ether ea cellulose e seng ea ionic, e entsoeng ka thepa ea tlhaho ea polymer e le thepa e tala 'me e hloekisitsoe ke letoto la lits'ebetso tsa lik'hemik'hale. Kajeno re tla ithuta ka ts'ebetso ea ts'ebeliso ea HPMC.
● Ho qhibiliha ha metsi: a ka qhibiliha ka metsing ka tekanyo efe kapa efe, mahloriso a phahameng ka ho fetisisa a itšetlehile ka ho teteana, 'me ho qhibiliha ha ho angoe ke PH.l Ho qhibiliha ha lintho tse phelang: HPMC e ka qhibiliha ka har'a litharollo tse ling tsa lintho tse phelang kapa litharollong tse metsi tse qhibilihang tsa tlhaho tse kang dichloroethane, tharollo ea ethanol, jj.
● Litšobotsi tsa gel ea mocheso: Gel e ka fetoloang e tla hlaha ha tharollo ea bona ea metsi e futhumatsoa mochesong o itseng, ka ts'ebetso e laoloang ea ho beha kapele.
● Ha ho na tjhaja ya ionic: HPMC ke ether ya cellulose e seng ionic mme e ke ke ya rarahana ka di-ion tsa tshepe kapa tsa organic ho etsa di-precipitate tse sa qhibiliheng.
● Ho teteana: Sistimi ea eona ea tharollo ea metsi e na le ho teteana, 'me phello ea ho teteana e amana le ho teteana ha eona, mahloriso le sistimi.
● Ho boloka metsi: HPMC kapa tharollo ea eona e ka monya le ho boloka metsi.
● Ho thehoa ha filimi: HPMC e ka etsoa filimi e boreleli, e thata, le e tenyetsehang, 'me e na le khanyetso e ntle ea mafura le oxidation.
● Ho hanyetsa li-enzyme: Tharollo ea HPMC e na le ho hanyetsa li-enzyme hantle le botsitso bo botle ba viscosity.
● Botsitso ba PH: HPMC e tsitsitse ho latela asiti le alkali, 'me pH ha e amehe pakeng tsa 3-11. (10) Mosebetsi oa bokaholimo: HPMC e fana ka ts'ebetso ea bokaholimo tharollong ho fihlela emulsification e hlokahalang le litlamorao tse sireletsang tsa colloid.
● Thepa e thibelang ho oa: HPMC e eketsa thepa ea thixotropic ea sistimi ho phofo ea putty, seretse, sekhomaretsi sa tile le lihlahisoa tse ling, 'me e na le bokhoni bo botle ba ho thibela ho oa.
● Ho qhalana: HPMC e ka fokotsa tsitsipano ya difacial pakeng tsa mekhahlelo mme ya etsa hore karolo e qhalakantsweng e qhalakanngwe ka ho lekana hore e be marothodi a boholo bo loketseng.
● Ho khomarela: E ka sebelisoa e le sehokelo bakeng sa bongata ba pigment: pampiri ea 370-380g/l³, 'me e ka boela ea sebelisoa ho lipente le likhomaretsi.
● Ho tlotsa: E ka sebelisoa ho rabara, asbestos, samente le lihlahisoa tsa letsopa ho fokotsa khohlano le ho ntlafatsa ho kenella ha konkreite.
● Ho emisoa: Ho ka thibela dikarolwana tse tsitsitseng ho na le pula le ho thibela ho thehwa ha pula.
● Emulsification: Hobane e ka fokotsa khatello ea bokaholimo le ea interfacial, e ka tsitsisa emulsion.
● Colloid e sireletsang: Lera le sireletsang le thehoa holim'a marotholi a hasaneng ho thibela marotholi ho kopana le ho kopana ho fihlela phello e tsitsitseng ea tšireletso.
