HPMC Hydroxypropyl methyl cellulose, eo hape e tsejoang e le hydroxypropyl methyl cellulose ether (HPMC), cellulose hydroxypropyl methyl ether, ke khetho ea cellulose e hloekileng haholo ea k'hothone e le lisebelisoa tse tala, tlasa maemo a alkaline ka etherification e khethehileng le boitokiso.
Hydroxypropyl methyl cellulose HPMC e sebelisoang kahong, selulose ether e ekelitsoeng palo e tlase haholo, empa e ka ntlafatsa haholo ts'ebetso ea seretse se metsi, ts'ebetso ea kaho ea seretse ke tlatsetso e kholo. Hona joale, hydroxypropyl methyl cellulose e sebelisoang ho seretse se ommeng sa cellulose ether haholo-holo ke hydroxypropyl methyl cellulose ether (HPMC). Hydroxypropyl methyl cellulose mohahong o omileng oa seretse HPMC haholo-holo e bapala karolo ea ho boloka metsi, ho tiisa, ho ntlafatsa ts'ebetso ea kaho.
1, seretse sa kaho sa plastering seretse
Ho boloka metsi a phahameng ho ka etsa hore samente e be le metsi ka botlalo, ho eketsa matla a tlamo, 'me ka nepo ho ka ntlafatsa matla a ho tsitsa le matla a ho kuta, ho ntlafatsa haholo phello ea kaho, ho ntlafatsa katleho ea mosebetsi.
2, putty ea ho hanyetsa metsi
Ka har'a putty HPMC hydroxypropyl methyl cellulose ether haholo-holo e bapala karolo ea ho boloka metsi, tlamahano le lubrication, ho qoba ts'ebetso ea mapetsong le ho felloa ke metsi 'meleng ho bakoang ke tahlehelo ea metsi ka potlako, le ho ntlafatsa ho khomarela ha putty, ho fokotsa ts'ebetso ea phallo e leketlileng kahare. kaho, e le hore kaho e batla e boreleli.
3, letoto la pente ea gypsum
Ka gypsum letoto la lihlahisoa HPMC hydroxypropyl methyl cellulose ether haholo-holo bapala ho boloka metsi, eketsa lubrication le liphello tse ling, ka nako e tšoanang e na le phello e itseng ea tieho, ho rarolla tshebetso ya kaho moropa cracking, matla a pele a ke ke ho fihlela ho bothata, ka lelefatsa. nako ea ho sebetsa.
4, moemeli oa sebopeho
Haholo-holo e sebelisoa e le motenya, e ka ntlafatsa matla a tsitsitseng le matla a ho kuta, ea ntlafatsa ho roala holim'a metsi, ea matlafatsa ho khomarela le matla a tlamahano.
5, seretse sa ho kenya ka ntle
HPMC Hydroxypropyl methyl cellulose, cellulose ether linthong tse lebisang tlhokomelo ho tlamahaneng, ho eketsa matla, ho etsa hore ho be bonolo ho koahela seretse, ho ntlafatsa katleho ea mosebetsi, ka nako e ts'oanang ho hanyetsa phallo e tsitsitseng, ts'ebetso e phahameng ea ho boloka metsi e ka lelefatsa nako ea ho sebetsa ea seretse, ntlafatsa shrinkage le mocheso mokhathala ho hanyetsa, ntlafatsa boleng ba bokaholimo, ntlafatsa matla a tlamahano.
6, setlamo sa lithaele tsa ceramic
Ho boloka metsi a phahameng ho ke ke ha khoneha pele ho soak kapa ho koloba lithaele tsa ceramic le setsi, ho ntlafatsa haholo matla a eona a tlamahano, slurry e ka ba potoloho e telele ea kaho, e boreleli, e ts'oanang, kaho e loketseng, 'me e na le khanyetso e ntle ea mongobo.
7, moemeli oa ho tlatsa seam, moemeli oa ho kopanya
Ho eketsoa ha hydroxypropyl methyl cellulose HPMC selulose ether e etsa hore e be le sekhomaretsi se setle sa mothapo, ho fokotseha ho tlase le ho hanyetsa ho hoholo, ho sireletsa thepa ea motheo ho senyeha ha mochini, ho qoba tšusumetso ea ho kenella mohahong oohle.
8, thepa ea ho ikemela
Hydroxypropyl methyl cellulose cellulose ether bond e tsitsitseng ho etsa bonnete ba hore ho na le metsi a lekaneng le bokhoni ba ho ikemela, ho laola sekhahla sa ho boloka metsi e le hore se ka tiisa kapele, ho fokotsa ho phunyeha le ho phunyeha.
9. Pente ea latex
Hydroxypropyl methyl cellulose indastering ea ho roala cellulose ether e le ea pele ea filimi, sesebelisoa se teteaneng, emulsifier le stabilizer e sebelisitsoeng, e etsa hore e be le khanyetso e ntle ea abrasion, ho roala, sekhomaretsi, ho ntlafatsa boleng ba boleng ba PH ba tsitsipano ea bokaholimo, le phello ea motsoako oa organic solvent. e betere hape, ts'ebetso ea Gao Baoshui e etsa hore e be le thepa e ntle ea borashe le phallo.
10. Li-ceramics tsa khekhe ea linotsi
Ka lirafshoa tse ncha tsa khekhe ea linotši, billet e fuoa lubricity, ho boloka metsi le ho matlafatsa matla.
Lihlahisoa tse ntle tsa hydroxypropyl methyl cellulose li ka rarolla bothata ba ho boloka metsi tlas'a mocheso o phahameng. Nakong ea mocheso o phahameng, haholo-holo libakeng tse chesang le tse omileng le kaho ea lera le tšesaane lehlakoreng le nang le letsatsi, HPMC ea boleng bo holimo ea hlokahala ho ntlafatsa ho boloka metsi a slurry. HPMC ea boleng bo holimo, ho tšoana ho ntle haholo, lihlopha tsa eona tsa methoxy le hydroxypropyl hammoho le kabo ea junifomo ea limolek'hule tsa cellulose, li ka ntlafatsa bond ea hydroxyl le ether holim'a liathomo tsa oksijene le bokhoni ba bond bond ea metsi, ho etsa hore metsi a sa lefelloeng a be metsi a kopaneng, e le hore a atlehe. laola mouoane oa metsi o bakoang ke mocheso o phahameng oa leholimo, ho finyella ho boloka metsi a phahameng.
Boleng bo phahameng ba hydroxypropyl methyl cellulose e ka qhalakana ka mokhoa o ts'oanang le ka katleho ka har'a seretse sa samente le lihlahisoa tsa samente, 'me ea paka likaroloana tsohle tse tiileng,' me ea etsa lera la filimi e kolobisang, mongobo o botlaaseng ka nako e telele o lokollotsoe butle butle, le inorganic cementitious material hydration reaction. , e le ho netefatsa matla a tlamahano le matla a khatello ea thepa. Ka hona, ka mocheso o phahameng oa lehlabula kaho, e le ho finyella phello ea paballo ea metsi, ho ea ka mokhoa oa ho eketsa lihlahisoa tsa boleng bo phahameng ba HPMC, ho seng joalo, ho tla ba le ho omisa ka potlako ho bakoang ke ho haella ha metsi, ho fokotsa matla, ho phunyeha, moqomo o se nang letho. ho oa le mathata a mang a boleng, empa hape ho eketsa bothata ba kaho ea basebetsi. Ha mocheso o fokotseha, palo ea HPMC e ka fokotsoa butle-butle, 'me phello e tšoanang ea ho boloka metsi e ka finyelloa.
