Phapang ea hydroxypropyl methylcellulose HPMC le hydroxyethyl cellulose HEC

Ho na le indasteri ea monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, lehydroxyethyl cellulose, tse sebelisoang haholo.Har'a mefuta e meraro ea selulose, e thata ka ho fetisisa ho e khetholla ke hydroxypropyl methylcellulose le hydroxyethyl cellulose.A re ke re khetholle mefuta ena e 'meli ea cellulose ka tšebeliso le mesebetsi ea eona.

Joalo ka sesebelisuoa se seng sa ionic, hydroxyethyl cellulose e na le lintho tse latelang ho kenyelletsa ho emisa, ho tenya, ho qhalakanya, ho phaphamala, ho kopanya, ho etsa filimi, ho boloka metsi le ho fana ka li-colloid tse sireletsang:

1. HEC ka boeona ha e na ionic 'me e ka phela hammoho le mefuta e mengata e mengata ea li-polymers tse qhibilihang ka metsing, li-surfactants le matsoai.Ke colloidal thickener e babatsehang e nang le litharollo tse phahameng tsa electrolyte.

2. Ha ho bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, bokhoni ba ho qhala ba HEC bo bobe ka ho fetisisa, empa colloid e sireletsang e na le matla a matla ka ho fetisisa.

3. Matla a ho boloka metsi a phahame ka makhetlo a mabeli ho feta a methyl cellulose, 'me a na le taolo e ntle ea ho phalla.

4. HEC e qhibiliha ka metsing a chesang kapa a batang, 'me ha e na mocheso o phahameng kapa o belang, kahoo e na le mefuta e mengata ea ho qhibiliha le li-viscosity, hammoho le gelation e sa chesang.

Tšebeliso ea HEC: ka kakaretso e sebelisoa e le moemeli oa thickening, moemeli oa tšireletso, sekhomaretsi, stabilizer le ho lokisetsa emulsion, jelly, mafura, lotion, ho hloekisa mahlo.

Kenyelletso ea kopo ea Hydroxypropyl methylcellulose (HPMC):

1. Indasteri ea ho roala: e le thickener, dispersant le stabilizer indastering ea ho roala, e na le tumellano e ntle ea metsi kapa li-solvents tse phelang.joalo ka se tlosang pente.

2. Tlhahiso ea Ceramic: e sebelisoa haholo e le tlamahano ha ho etsoa lihlahisoa tsa ceramic.

3. Tse ling: Sehlahisoa sena se boetse se sebelisoa haholo indastering ea letlalo, lihlahisoa tsa pampiri, ho boloka litholoana le meroho le indasteri ea masela, joalo-joalo.

4. Khatiso ea enke: e le thickener, dispersant le stabilizer indastering ea enke, e na le tumellano e ntle ea metsi kapa li-solvents tsa manyolo.

5. Plastiki: e sebelisoa e le moemeli oa ho lokolla hlobo, softener, lubricant, joalo-joalo.

6. Polyvinyl chloride: E sebelisoa e le dispersant tlhahiso ea polyvinyl chloride, 'me ke eona ntho e ka sehloohong e thusang bakeng sa ho lokisa PVC ka polymerization ea ho fanyeha.​

7. Indasteri ea kaho: E le setsi sa ho boloka metsi le se fokotsang metsi bakeng sa lehlabathe la samente, se etsa hore lehlabathe le pompong.E sebelisoa e le setlamo sa pente, gypsum, putty powder kapa lisebelisoa tse ling tsa mohaho ho ntlafatsa ho ata le ho lelefatsa nako ea ts'ebetso.E sebelisoa e le pente bakeng sa lithaele tsa ceramic, 'mabole, mokhabiso oa polasetiki, e le sehlahisoa sa pente, hape e ka fokotsa bongata ba samente.Ho bolokoa ha metsi ha HPMC ho ka thibela slurry ho phatloha ka lebaka la ho omella kapele ka mor'a kopo, le ho matlafatsa matla ka mor'a ho thatafala.
