Product Description:
Methyl Hydroxyethyl Cellulose (MHEC) yog non-ionic cellulose ether uas tau siv dav hauv cov khoom siv. Nws tuaj yeem yaj hauv dej kub lossis dej txias los tsim cov kua dej ntshiab nrog ib qho viscosity. Cov khoom ntawm methyl hydroxyethyl cellulose thiab methylcellulose yog qhov zoo sib xws, tab sis muaj hydroxyethyl ua rau MHEC cellulose ntau soluble hauv dej, cov tshuaj yog sib xws nrog ntsev thiab muaj ntau dua aggregation kub.
Daim ntawv thov:
MHEC cellulose hmoov yog siv dav hauv kev lag luam hauv tsev. Piv txwv li, nws tuaj yeem siv rau hauv pobzeb nplaum, sib koom ua ke, tus kheej-leveling mortar, plaster, skim coat, xim thiab coatings, thiab lwm yam. Raws li cov non-ionic cellulose ether, HMEC hmoov muaj qhov zoo stabilization thiab thickening nyhuv hauv cov xim, uas tuaj yeem ua rau cov xim ua kom zoo hnav tsis kam. Lubricity ntawm MHEC cellulose tuaj yeem txhim kho kev ua haujlwm ntawm mortar zoo heev (xws li txhim kho cov ntawv cog lus lub zog ntawm mortar, txo cov dej nqus dej, thiab txhim khu kev tiv thaiv sag ntawm mortar), uas muaj txiaj ntsig zoo rau kev txhim kho kev ua haujlwm.
Tsuas yog rau kev tsim kho kev lag luam, methyl hydroxyethyl cellulose kuj tseem siv rau hauv kev lag luam khoom noj, tshuaj txhua hnub, thiab lwm yam. Hauv kev lag luam khoom noj khoom haus, HEMC cellulose yog siv los ua adhesion, emulsification, film formation, thickening, suspending, dispersing, water retention agents, etc. Nyob rau hauv cov tshuaj txhua hnub, nws yog siv los ua ib qho ntxiv rau tshuaj txhuam hniav, tshuaj pleev ib ce, thiab tshuaj ntxuav tes.
Pob: 25 kgs / hnab los yog raws li koj thov.
Cia: Khaws ntawm qhov chaw muaj cua, qhuav.
Cov txheej txheem ua tiav: International Standard.
