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

Tšebeliso ea Phofo ea Hpmce ka hasana ka ho lekana le ka katleho ka har'a seretse sa samente le lihlahisoa tse thehiloeng ho gypsum, e phuthela likaroloana tsohle tse tiileng 'me e etsa filimi e kolobisang. Mongobo o ka tlase o lokolloa butle-butle ka nako e telele, 'me o feta karabelong ea metsi ka thepa e sa pheleng ea samente, ka hona e netefatsa matla a ho tlamahana le matla a ho hatella a thepa.

Ka hona, kahong ea lehlabula e nang le mocheso o phahameng, e le ho fihlela phello ea ho boloka metsi, ho hlokahala ho eketsa bongata bo lekaneng bahydroxypropyl methyl celluloseho ya ka foromo, ho seng jwalo mathata a boleng a kang ho se lekane ha metsi, matla a fokotsehileng, ho petsoha, ho phunya le ho arohana ho bakwang ke ho oma ka potlako ho tla etsahala, mme ho tla boela ho eketse bothata ba basebetsi ba kaho. Ha mocheso o ntse o fokotseha, bongata ba hydroxypropylmethylcellulose bo ka fokotswa butle-butle, mme phello e tshwanang ya ho boloka metsi e ka fihlellwa.

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

1. Ho tšoana ha hydroxypropyl methyl cellulose

E ts'oananghydroxypropyl methyl cellulose, Sehlopha sa Methoxy le hydroxypropyl li ajoa ka ho lekana, 'me sekhahla sa ho boloka metsi se phahame.

2. Mocheso oa gel ea mocheso ea HPMC

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

3. Hydroxypropylmethylcelluloseho teteana

Ha viscosity eaHPMCho 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 eketsehileng ea hydroxypropyl methyl cellulose

Ha bongata ba hydroxypropyl methyl cellulose bo eketsoa bo le boholo, sekhahla sa ho boloka metsi sea phahama 'me phello ea ho boloka metsi e ba betere. Sebakeng sa keketseho ea 0.25-0.6%, sekhahla sa ho boloka metsi sea eketseha ka potlako ka keketseho ea bongata ba ho eketsa; Ha bongata ba ho eketsa bo ntse bo eketseha, mokhoa o ntseng o eketseha oa sekhahla sa ho boloka metsi oa fokotseha.
