Hydroxypropyl methyl cellulose ka har'a samente le plaster e thehiloeng ho gypsum

HPMC Hydroxypropyl methyl celluloseka har'a seretse sa samente le gypsum slurry, haholo-holo li bapala karolo ea ho boloka metsi le ho teteana, li ka ntlafatsa ho khomarela le ho hanyetsa ho salla ha slurry ka katleho.

Mocheso oa moea, mocheso le sekhahla sa khatello ea moea li ka ama sekhahla sa mouoane oa metsi ka har'a seretse sa samente le lihlahisoa tse thehiloeng ho gypsum. Kahoo linakong tse fapaneng, ho eketsa hydroxypropyl methyl cellulose palo e lekanang ea phello ea ho boloka metsi ea sehlahisoa ho na le liphapang tse itseng. Kaho ea konkreite, phello ea ho boloka metsi ea slurry e ka fetoloa ka ho eketsa kapa ho fokotsa bongata ba HPMC. Ho boloka metsi ha methyl cellulose ether mochesong o phahameng ke sesupo sa bohlokoa sa ho khetholla boleng ba methyl cellulose ether.

E babatsehanghydroxypropyl methyl celluloseLihlahisoa tsa letoto li ka rarolla bothata ba ho boloka metsi ka katleho tlas'a mocheso o phahameng. Nakong ea mocheso o phahameng, haholo-holo libakeng tse chesang le tse omileng le kaho e tšesaane ka lehlakoreng le chabileng, tlhoko ea HPMC ea boleng bo holimo ho ntlafatsa ho boloka metsi ha slurry; hydroxypropyl methyl cellulose (HPMC), ho tšoana ho hotle haholo, ke lihlopha tsa hydroxypropyl tsa oksijene le oksijene tse ajoang ka ho lekana ketane ea cellulose, li ka ntlafatsa hydroxyl le ether oksijene le metsi ka bokhoni ba ho kopanya hydrogen, ho etsa metsi a mahala, e le ho laola boemo ba leholimo bo chesang bo bakoang ke mongobo ho fetoha mouoane, ho fihlela ho boloka metsi a mangata.

Boleng bo phahameng ba hydroxypropyl methyl cellulose bo ka hasana ka ho lekana le ka katleho ka har'a seretse sa samente le lihlahisoa tsa plaster, 'me ba paka likaroloana tsohle tse tiileng,' me ba theha lera la filimi e kolobisang, mongobo o ka har'a setsi ka nako e telele o lokolloa butle-butle, le karabelo ea hydration ea thepa e sa pheleng, e le ho netefatsa matla a tlamahano le matla a khatello a thepa.

Kahong, e le ho fihlela phello ea paballo ea metsi, ho hlokahala ho eketsa boleng bo holimoHPMClihlahisoa ho latela mokhoa ona, ho seng jwalo, ho tla ba le ho oma kapele haholo ho bakwang ke ho se lekane ha metsi, phokotso ya matla, ho petsoha, mathata a boleng ba teramo e se nang letho le ho tsholoha ha metsi, empa hape ho eketsa bothata ba kaho ya basebetsi. Ha mocheso o ntse o fokotseha, bongata ba metsi a HPMC bo ka fokotswa butle-butle, mme phello e tshwanang ya ho boloka metsi e ka fihlellwa.
