HPMC yog Hydroxypropyl methyl cellulose ether thiab HEC yog hydroxyethyl cellulose ether.
Hydroxypropyl methyl cellulose (HPMC) kev taw qhia:
1, kev tsim kho kev lag luam: raws li dej thiab silt slurry dej tuav tus neeg saib xyuas, retarder ua slurry twj. Hauv plastering, gypsum, putty hmoov los yog lwm yam khoom siv hauv tsev ua cov nplaum, txhim kho daub thiab ua kom lub sijhawm ua haujlwm ntev. Siv rau pasting ceramic pobzeb, marble, yas kho kom zoo nkauj, muab tshuaj ntxiv dag zog tus neeg sawv cev, tseem tuaj yeem txo cov cement ntau npaum li cas.HPMCdej tuav kev ua tau zoo ua rau slurry tom qab daim ntawv thov yuav tsis yog vim qhuav sai heev thiab tawg, txhim khu lub zog tom qab hardening.
2, ceramic manufacturing: dav siv los ua nplaum hauv cov khoom siv ceramic.
3, txheej kev lag luam: nyob rau hauv kev lag luam txheej raws li ib tug thickener, dispersant thiab stabilizer, nyob rau hauv dej los yog organic solvents muaj ib tug zoo solubility. Raws li cov xim tshem tawm.
4, ink printing: nyob rau hauv lub ink lag luam ua ib tug thickener, dispersant thiab stabilizer, nyob rau hauv dej los yog organic solvents muaj ib tug zoo solubility.
5, yas: rau kev tso tawm tus neeg sawv cev, softener, lubricant, thiab lwm yam.
6, PVC: PVC ntau lawm ua ib tug dispersant, ncua kev kawm ntawv polymerization npaj ntawm PVC lub ntsiab auxiliaries. 7, Lwm tus: cov khoom no kuj tau siv dav hauv cov tawv nqaij, cov khoom lag luam ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile
Hydroxyethyl cellulose (HEC) kev taw qhia:
HEC Hydroxyethyl celluloseRaws li ib yam ntawm nonionic surfactant, ntxiv rau thickening, ntab, ntab, thiab zaj duab xis-forming, dispersion, dej, thiab muab ib tug tiv thaiv colloid, kuj muaj cov nram qab no cov khoom:
1, HEC soluble nyob rau hauv dej kub los yog dej txias, kub los yog boiling tsis nag los nag, ua rau nws muaj ib tug ntau yam ntawm solubility thiab viscosity zog, thiab tsis thermal gel;
2, nws cov non-ionic tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants, ntsev, yog ib qho zoo heev colloidal thickener uas muaj siab concentration ntawm electrolyte kua;
3, lub peev xwm tuav dej yog ob zaug siab dua methyl cellulose, nrog kev tswj xyuas zoo, 4, HEC dispersion muaj peev xwm piv nrog cov paub txog methyl cellulose thiab hydroxypropyl methyl cellulose dispersion muaj peev xwm yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloidal yog qhov muaj zog tshaj.
Kev siv: feem ntau yog siv los ua thickening tus neeg saib xyuas, tiv thaiv tus neeg sawv cev, nplaum nplaum, stabilizer thiab additive nyob rau hauv kev npaj ntawm emulsion, jelly, tshuaj pleev, tshuaj pleev ib ce, qhov muag clearing agent, suppository thiab ntsiav tshuaj, kuj siv raws li hydrophilic gel, skeleton khoom, kev npaj ntawm skeleton hom sustained tso kev npaj, kuj tuaj yeem siv ua stabilizer hauv cov khoom noj.
