Muaj cov monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, thiabhydroxyethyl cellulose, uas yog feem ntau siv. Ntawm peb hom cellulose, qhov nyuaj tshaj plaws kom paub qhov txawv yog hydroxypropyl methylcellulose thiab hydroxyethyl cellulose. Cia peb paub qhov txawv ntawm ob hom cellulose los ntawm lawv cov kev siv thiab kev ua haujlwm.
Raws li non-ionic surfactant, hydroxyethyl cellulose muaj cov khoom nram qab no ntxiv rau kev ncua, thickening, dispersing, flotation, bonding, film-forming, dej tuav thiab muab kev tiv thaiv colloids:
1. HEC nws tus kheej tsis yog-ionic thiab tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants, thiab ntsev. Nws yog ib qho zoo heev colloidal thickener uas muaj cov ntsiab lus siab electrolyte.
2. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj plaws, tab sis kev tiv thaiv colloid muaj peev xwm muaj zog tshaj plaws.
3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua.
4. HEC yog soluble nyob rau hauv dej kub los yog txias, thiab tsis precipitate ntawm kub los yog boiling, yog li nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, raws li zoo raws li tsis-thermal gelation.
Kev siv HEC: feem ntau yog siv los ua tus neeg sawv cev thickening, tus neeg sawv cev tiv thaiv, nplaum, stabilizer thiab kev npaj ntawm emulsion, jelly, ointment, lotion, eye clearing.
Hydroxypropyl methylcellulose (HPMC) daim ntawv thov kev taw qhia:
1. Txheej kev lag luam: raws li ib tug thickener, dispersant thiab stabilizer nyob rau hauv cov txheej txheem kev lag luam, nws muaj zoo compatibility nyob rau hauv dej los yog organic solvents. raws li cov xim tshem tawm.
2. Ceramic manufacturing: dav siv los ua cov ntaub ntawv hauv kev tsim cov khoom siv ceramic.
3. Lwm tus: Cov khoom no kuj tau siv dav hauv tawv, ntawv cov khoom lag luam, kev txuag txiv hmab txiv ntoo thiab zaub thiab kev lag luam textile, thiab lwm yam.
4. Ink printing: raws li ib tug thickener, dispersant thiab stabilizer nyob rau hauv lub lag luam number case, nws muaj zoo compatibility nyob rau hauv dej los yog organic solvents.
5. Yas: siv los ua pwm tso tus neeg sawv cev, softener, lubricant, thiab lwm yam.
6. Polyvinyl chloride: Nws yog siv los ua ib qho dispersant hauv kev tsim cov polyvinyl chloride, thiab nws yog tus neeg sawv cev tseem ceeb rau kev npaj ntawm PVC los ntawm kev ncua polymerization.
7. Kev tsim kho kev lag luam: Raws li tus neeg saib xyuas dej-retaining thiab retarder rau cement xuab zeb slurry, nws ua rau cov xuab zeb slurry pumpable. Siv los ua cov ntaub ntawv hauv plastering paste, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev los txhim kho kev sib kis thiab ua haujlwm ntev. Nws yog siv los ua cov tshuaj pleev xim rau cov nplais pobzeb, marble, yas kho kom zoo nkauj, ua cov tshuaj pleev ib ce, thiab nws tuaj yeem txo cov cement. Cov dej tuav ntawm HPMC tuaj yeem tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening.
