01. Phapang lipakeng tsa hydroxypropyl methyl ea bohata le hydroxypropyl methyl ea boleng bo holimo.
Ponahalo: Setache se hloekileng sa HPCM se bonahala se le homogeneous haholo, pakeng tsa 0.3 le 0.4 g/ml. Amylum e tlama ho starch kahoo HPCM ke mokelikeli 'me ha e na khatello ea maikutlo ho feta e tloaelehileng e tlosa chefo.
Maemo: starch e tletseng starch, hpm powder, fiber tlas'a microscope kapa magnifying glass, HPCM mofuta oa starch e ka laolang starch kapa starch le lentile.
Monko: Hydroxypropyl methylcellulose e hloekileng HPMC ha e khone ho fofonela ammonia, starch le joala; HPMC e ka fofonela mefuta eohle ea monko, leha e sa latsoehe, e tla ikutloa e fokola Shen.
Tharollo ea metsi: e hloekileng, HPMC methylcellulose demethoxypropyl brinzolamide aqueous solution e hlakile, tekanyo ea ho boloka metsi a bobebe ≥ 97%; Diluted hydrolyzed cellulose-diluted HPMC hydrolyzed cellulose e senyehile ho feta, sekhahla sa ho boloka metsi ha se fihle ho 80%.
02. Ho boloka methyl cellulose mocheso o phahameng ke pontšo ea bohlokoa ho fumana boleng ba methyl cellulose ether. Lintho tse kang mocheso oa moea, mocheso oa moea le lebelo la moea li ama ho feto-fetoha ha samente slurry le lihlahisoa tsa gypsum. Ka hona, ho kenyelletsa palo e lekanang ea lihlahisoa tsa HPMC ka linako tse fapaneng tsa selemo, ho na le liphapang tse itseng molemong oa ho boloka metsi. Ts'ebetsong e khethehileng ea ho sebetsa, phello ea serosa e mongobo e ka lokisoa ka ho fokotsa palo ea HPMC e ekelitsoeng. Hydroxypropyl methylcellulose HPMC ea boleng bo phahameng e ka rarolla bothata ba ho boloka metsi a mocheso o phahameng.
Methyl cellulose ea boleng bo phahameng e ka ajoa ka mokhoa o ts'oanang le ka katleho ka seretse sa samente le lihlahisoa tsa plastering, ho etsa filimi e tiileng, eo butle-butle e lokolloang ho tloha setsing sa motheo 'me e theha karabelo ea hydrophilic ka lisebelisoa tsa inorganic curling, kahoo e tiisa matla le ho tiea. HPMC cellulose methyl propoxylate ke boleng le junifomo, 'me oksijene ea ethyl bromide le propionic acid lihlopha hammoho le molek'hule cellulose ketane ke junifomo, e leng ho ntlafatsa oksijene le hydrogen tlamahano ea e mong le e athomo ea bohlokoa ea hydroxyl le ether Metsi a tlaase a ka fetola metsi a mahala hore e be metsi a bolokang letlalo, kahoo a laola ka katleho ho hlahisa metsi a tsoang moeeng, mocheso o phahameng oa metsi le mocheso o phahameng.
Ka lebaka la kaho e phahameng ea mocheso lehlabuleng, e le ho finyella phello ea ho boloka metsi, hoa hlokahala ho eketsa lihlahisoa tsa boleng bo phahameng ba HPMC ho ea ka foromo, ho seng joalo ho tla baka mathata a kang ho omisa ka mokhoa o feteletseng, matla a tlaase, ho phunyeha, ho tsosoa ho se nang letho le ho tlohela mosebetsi, le ho eketsa bothata ba ho haha bakeng sa basebetsi. Ha o ntse o theola mocheso, hoa khoneha ho fokotsa butle-butle palo ea HPMC e ekelitsoeng le ho fumana phello e tšoanang ea ho boloka metsi.
