Selelekela sa Hydroxypropyl methyl cellulose (HPMC):
1, indasteri ea kaho: joalo ka sesebelisoa sa ho boloka metsi le silt seretse, retarder ho etsa pompo ea slurry. Ho plaster, gypsum, putty powder kapa lisebelisoa tse ling tsa mohaho e le sekhomaretsi, ntlafatsa daub le ho lelefatsa nako ea ts'ebetso. E sebelisetsoa ho pata lithaele tsa ceramic, 'mabole, mokhabiso oa polasetiki, sekontiri se matlafatsang, se ntse se ka fokotsa litekanyetso tsa samente.HPMCts'ebetso ea ho boloka metsi e etsa hore slurry ka mor'a kopo e se ke ea bakoa ke ho omella ka potlako le ho phatloha, ho matlafatsa matla ka mor'a ho thatafala.
2, tlhahiso ea ceramic: e sebelisoa haholo e le sekhomaretsi ha ho etsoa lihlahisoa tsa ceramic.
3, indasteri ea ho roala: indastering ea ho roala e le motenya, dispersant le stabilizer, ka har'a metsi kapa li-solvents tsa manyolo li na le solubility e ntle. E le ho tlosa pente.
4, khatiso ea enke: indastering ea enke e le motenya, dispersant le stabilizer, ka metsing kapa lihlapolli tsa manyolo li na le solubility e ntle.
5, polasetiki: bakeng sa ho theha moemeli oa tokollo, softener, lubricant, joalo-joalo.
6, PVC: PVC tlhahiso e le dispersant, ho emisoa polymerization lokisetsa ea PVC bathusi ba ka sehloohong. 7, Tse ling: sehlahisoa sena se boetse se sebelisoa haholo indastering ea letlalo, lihlahisoa tsa pampiri, ho boloka litholoana le meroho le indasteri ea masela.
Selelekela sa Hydroxyethyl cellulose (HEC):
HEC Hydroxyethyl cellulose, joalo ka mofuta oa nonionic surfactant, ntle le ho teteaneng, ho phaphamala, ho phaphamala, le ho etsa lifilimi, ho hasana, metsi, le ho fana ka colloid e sireletsang, e boetse e na le litšobotsi tse latelang:
