Hydroxypropyl methylcellulose e sebelisoa ka bongata bo fapaneng ka lebaka la boemo ba leholimo

Lintho tse kang mocheso oa moea, mocheso le khatello ea moea li tla ama sekhahla sa ho fetoha ha mongobo seretseng sa samente le lihlahisoa tse thehiloeng ho gypsum.Ka hona, ka linako tse fapaneng tsa selemo, phello ea ho boloka metsi ea palo e lekanang ea HPMC e fapane.

Mohahong o ikhethileng, phello ea ho boloka metsi ea slurry e ka fetoloa ka ho eketsa kapa ho fokotsa palo ea HPMC e ekelitsoeng.Ho boloka metsi a hydroxypropyl methyl cellulose ether tlas'a maemo a mocheso o phahameng ke sesupo sa bohlokoa ho khetholla boleng ba hydroxypropyl methyl cellulose ether.Lihlahisoa tse ntle ka ho fetisisa tsa HPMC li ka rarolla bothata ba ho boloka metsi ka mocheso o phahameng.
Linakong tsa mocheso o phahameng, haholo-holo libakeng tse chesang le tse omileng le kaho ea lera le tšesaane lehlakoreng le chabileng, HPMC ea boleng bo holimo ea hlokahala ho ntlafatsa ho boloka metsi a seretse.HPMC ea boleng bo holimo e na le ts'ebetso e ntle haholo.Lihlopha tsa eona tsa methoxy le hydroxypropoxy li ajoa ka mokhoa o ts'oanang hammoho le ketane ea molek'hule ea cellulose, e ka ntlafatsang bokhoni ba liathomo tsa oksijene holim'a li-bond tsa hydroxyl le ether ho kopana le metsi ho theha likamano tsa hydrogen, E le hore metsi a sa lefelloeng a fetohe metsi a tlamiloeng, ka tsela eo a laola ka katleho. ho fetoha mouoane ha metsi ho bakoang ke mocheso o phahameng oa leholimo, le ho boloka metsi a mangata.
HPMC ea boleng bo holimo ea cellulose e ka qhalakanngoa ka mokhoa o ts'oanang le ka katleho ka har'a seretse sa samente le lihlahisoa tse thehiloeng ho gypsum, 'me ea phuthela likaroloana tsohle tse tiileng,' me ea etsa filimi ea ho kolobisa.Metsi a ka setsing a lokolloa butle-butle ka nako e telele.Thepa e khutsufalitsoeng e etsa karabelo ea hydration ho netefatsa matla a tlamahano le matla a hatellang a thepa.Ka hona, mohahong o phahameng oa mocheso oa lehlabula, e le ho finyella phello ea ho boloka metsi, lihlahisoa tsa boleng bo phahameng ba HPMC li tlameha ho ekeletsoa ka bongata bo lekaneng ho ea ka foromo, ho seng joalo, ho haella ha metsi, matla a fokotsehileng, ho phunyeha, ho koala le ho oela ho bakoang. ka ho omisa ho feteletseng ho tla etsahala.E boetse e eketsa bothata ba kaho bakeng sa basebetsi.Ha mocheso o fokotseha, palo ea HPMC e ekelitsoeng e ka fokotsoa butle-butle, 'me phello e tšoanang ea ho boloka metsi e ka finyelloa.
