Ke lintlha life tse amang ho bolokoa ha metsi a hydroxypropyl methyl cellulose?

Tšebeliso ea phofo ea Hpmce ka qhalakanngoa ka mokhoa o ts'oanang le ka katleho ka seretse sa samente le lihlahisoa tse thehiloeng ho gypsum, ho phuthela likaroloana tsohle tse tiileng le ho etsa filimi ea ho kolobisa. Mongobo o botlaaseng o lokolloa butle-butle ka nako e telele, 'me o kenella karabelo ea hydration ka lisebelisoa tsa samente tse sa sebetseng, ka hona ho netefatsa matla a ho kopanya le matla a khatello ea thepa.

Ka hona, ka mocheso o phahameng oa lehlabula kaho, e le ho finyella phello ea ho boloka metsi, ho hlokahala ho eketsa chelete e lekaneng eahydroxypropyl methyl celluloseho ea ka foromo, ho seng joalo mathata a boleng a kang hydration e sa lekaneng, matla a fokotsehileng, ho phunyeha, ho pata, le ho arohana ho bakoang ke ho omisa ka potlako ho tla etsahala, hape ho tla eketsa bothata ba basebetsi kahong. Ha mocheso o ntse o fokotseha, palo ea hydroxypropylmethylcellulose e ka fokotseha butle-butle, 'me phello e tšoanang ea ho boloka metsi e ka finyelloa.

Ho boloka metsi a hydroxypropyl methyl cellulose ho susumetsoa ke mocheso le lintlha tse latelang:

1. Homogeneity ea hydroxypropyl methyl cellulose

Homogeneoushydroxypropyl methyl cellulose, sehlopha sa Methoxy le hydroxypropyl li ajoa ka ho lekana, 'me tekanyo ea ho boloka metsi e phahame.

2. Mocheso oa gel ea mocheso oa HPMC

Gel ea mocheso e na le mocheso o phahameng le tekanyo e phahameng ea ho boloka metsi; Ho fapana le hoo, sekhahla sa ho boloka metsi se tlase.

3. Hydroxypropylmethylcelluloseviscosity

Ha viscosity eaHPMCe eketseha, sekhahla sa ho boloka metsi le sona sea eketseha; Ha viscosity e fihla boemong bo itseng, keketseho ea ho boloka metsi e atisa ho ba butle-butle.

4. Palo e ekelitsoeng ea hydroxypropyl methyl cellulose

Ha palo ea hydroxypropyl methyl cellulose e eketsoa e le kholoanyane, e phahamisa sekhahla sa ho boloka metsi le phello e ntle ea ho boloka metsi. Ka kakaretso ea 0.25-0.6% ea tlatsetso, sekhahla sa ho boloka metsi se eketseha ka potlako ka keketseho ea palo ea tlatsetso; Ha palo ea ho boloka metsi e ntse e eketseha, mokhoa o ntseng o eketseha oa ho boloka metsi oa fokotseha
