Raws li ib tug non-ionic surfactant,hydroxyethyl cellulose(HEC) muaj cov khoom nram qab no ntxiv rau cov thickening, suspending, binding, flotation, film-forming, dispersing, tuav dej thiab muab kev tiv thaiv colloids:
1. 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, thiab non-thermal gelation;
2. Cov uas tsis yog-ionic nws tus kheej tuaj yeem ua ke nrog lwm cov dej-soluble polymers, surfactants thiab ntsev nyob rau hauv ntau yam, thiab yog ib qho zoo heev colloidal thickener uas muaj 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.
Yuav siv hydroxyethyl cellulose li cas?
1. koom ncaj qha rau hauv kev tsim khoom
1. Ntxiv dej huv rau hauv lub thoob loj uas muaj lub tshuab ua haujlwm siab.
2. Pib nplawm tsis tu ncua ntawm qhov ceev thiab maj mam sieve cov hydroxyethyl cellulose rau hauv cov tshuaj sib npaug.
3. Txuas ntxiv stirring kom txog thaum tag nrho cov khoom yog soaked los ntawm.
4. Tom qab ntawd ntxiv cov khoom tiv thaiv xob laim, alkaline additives xws li pigments, dispersing aids, ammonia dej.
5. Sib tov kom txog thaum tag nrho cov hydroxyethyl cellulose yog yaj tag (lub viscosity ntawm cov tshuaj nce ntau heev) ua ntej ntxiv lwm yam khoom nyob rau hauv cov mis, thiab grind kom txog thaum nws ua.
