Hydroxyethyl cellulose (HEC) yog xim dawb los yog lub teeb daj, tsis muaj ntxhiab, tsis muaj tshuaj lom fibrous lossis hmoov hmoov, uas yog npaj los ntawm etherification cov tshuaj tiv thaiv ntawm alkaline cellulose thiab ethylene oxide (los yog chlorohydrin). Nonionic soluble cellulose ethers. Txij li HEC muaj cov khoom zoo ntawm thickening, suspending, dispersing, emulsifying, bonding, film-forming, tiv thaiv ya raws thiab muab kev tiv thaiv colloid, nws tau siv dav hauv kev tshawb nrhiav roj, txheej, kev tsim kho, tshuaj, khoom noj, textile, papermaking thiab polymer Polymerization. thiab lwm yam teb. 40 mesh sieving tus nqi ≥ 99%;
Cov tsos mob: dawb mus rau lub teeb daj fibrous los yog powdery khoom, non-toxic, tasteless, soluble nyob rau hauv dej. Insoluble nyob rau hauv cov organic solvents.
Lub viscosity hloov me ntsis hauv thaj tsam ntawm PH tus nqi 2-12, tab sis lub viscosity txo qis tshaj qhov ntau. Nws muaj cov yam ntxwv ntawm thickening, suspending, khi, emulsifying, dispersing, tswj dej noo thiab tiv thaiv colloid. Kev daws teeb meem hauv qhov sib txawv viscosity tuaj yeem npaj tau. Tsis ruaj tsis khov nyob rau hauv ib txwm kub thiab siab, zam cov av noo, tshav kub, thiab kub, thiab muaj exceptional zoo ntsev solubility rau dielectrics, thiab nws cov aqueous tov tso cai rau siab concentrations ntawm ntsev kom nyob ruaj khov.
Cov khoom tseem ceeb:
Raws li non-ionic surfactant, hydroxyethyl cellulose muaj cov khoom nram qab no ntxiv rau cov thickening, suspending, binding, floating, film-forming, dispersing, dej tuav thiab muab kev tiv thaiv colloid:
1. HEC yog soluble nyob rau hauv dej kub los yog dej txias, thiab tsis precipitate ntawm kub los yog boiling, kom nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, thiab tsis-thermal gelation;
2. Nws yog non-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 rau high-concentration electrolyte daws;
3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua.
4. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj.
