Tšebeliso ea mantlha le liphapang tsa hydroxypropyl methylcellulose HPMC le hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, le hydroxyethyl cellulose e nang le indasteri ea monosodium glutamate li sebelisoa ka bongata bo boholo.Ho thata ka ho fetisisa ho khetholla har'a mefuta ena e meraro ea selulose ke hydroxypropyl methylcellulose le hydroxyethyl cellulose.Ka tlase re tla khetholla mefuta ena e 'meli ea selulose ka tšebeliso ea eona le ts'ebetso ea eona.

Joalo ka sesebelisuoa se seng sa ionic, hydroxyethyl cellulose e na le thepa e latelang ho kenyelletsa mesebetsi ea ho emisa, ho tenya, ho qhalakanya, ho phaphamala, ho kopanya, ho etsa filimi, ho boloka metsi le ho fana ka colloid e 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 bakeng sa tharollo e nang le li-electrolyte tse phahameng haholo.

2. Ha ho bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, bokhoni ba ho qhalakanngoa ba HEC bo bobe ka ho fetisisa, empa bokhoni ba ho sireletsa li-colloid ke bona bo 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 fokotsehe ka mocheso o phahameng kapa ho belisoa, e leng se etsang hore e be le mefuta e mengata ea ho qhibiliha le litšoaneleho tsa viscosity, le gelation e se nang mocheso.

HEC e sebelisoa: ka kakaretso e sebelisoa e le motenya, moemeli oa tšireletso, sekhomaretsi, stabilizer le ho lokisetsa emulsion, jelly, mafura, lotion, mahlo a hlakileng.

Kenyelletso ea kopo ea Hydroxypropyl methylcellulose (HPMC):

1. Indasteri ea ho roala: E sebelisoa e le motenya, dispersant le stabilizer indastering ea ho roala, 'me e na le tumellano e ntle ea metsi kapa li-solvents tsa manyolo.E le ho tlosa pente.

2. Indasteri ea ho etsa lirafshoa: E sebelisoa haholo e le tlamahano ha ho etsoa lihlahisoa tsa ceramic.

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

4. Khatiso ea enke: E sebelisoa e le motenya, dispersant le stabilizer indastering ea enke, 'me e na le tumellano e ntle ea metsi kapa li-solvents.

5. Plastiki: e sebelisoa e le ho etsa moemeli oa ho lokolla, ho nolofatsa, setlolo, joalo-joalo.

6. Polyvinyl chloride: E sebelisoa e le dispersant tlhahiso ea polyvinyl chloride, 'me ke moemeli ea ka sehloohong ea thusang ho lokisetsa PVC ka ho emisa polymerization.the

7. Indasteri ea kaho: E le moemeli oa ho boloka metsi le ho fokotsa litšila tsa lehlabathe la samente, e ka etsa hore seretse se pompehe.Ka samente, gypsum, putty powder kapa lisebelisoa tse ling tsa mohaho e le setlamo ho ntlafatsa ho ata le ho lelefatsa nako ea mosebetsi.E ka sebelisoa e le lithaele tsa peista, 'mabole, mokhabiso oa polasetiki, matlafatso ea peista, hape e ka fokotsa bongata ba samente.Ts'ebetso ea ho boloka metsi ea HPMC e thibela slurry ho phatloha ka lebaka la ho omella kapele ka mor'a kopo, 'me e matlafatsa matla ka mor'a ho thatafala.
