Product Description:
Hydroxyethyl cellulose (HEC) yog dawb los yog lub teeb daj, tsis muaj ntxhiab, tsis muaj tshuaj lom hmoov. Nws yog npaj los ntawm theem pib cellulose thiab ethylene oxide (los yog chloroethane) los ntawm etherification. Nws yog non-ionic soluble cellulose ether. Vim HEC cellulose muaj cov yam ntxwv zoo ntawm thickening, ncua kev kawm ntawv, dispersion, emulsification, adhesion, tsim zaj duab xis, tiv thaiv ya raws, thiab kev tiv thaiv ntawm colloids, nws yog dav siv nyob rau hauv roj av extraction, coatings, kev tsim kho, tshuaj thiab zaub mov, textiles, papermaking, thiab lwm teb.
Daim ntawv thov:
1. Hydroxyethyl cellulose hmoov yuav yaj nyob rau hauv dej kub thiab txias, thiab yuav tsis precipitate thaum rhuab los yog boiled. Vim li ntawd, nws muaj ntau yam solubility thiab viscosity yam ntxwv thiab non-thermogelability.
2. HEC tuaj yeem ua ke nrog lwm cov dej-soluble polymers, surfactants, thiab ntsev. HEC yog ib qho zoo heev colloidal thickener uas muaj high-concentration dielectric daws.
3. Nws lub peev xwm tuav dej yog ob zaug siab dua li ntawm methylcellulose, thiab nws muaj kev tswj xyuas zoo.
4. Muab piv rau methylcellulose thiab hydroxypropylmethylcellulose, HEC muaj peev xwm tiv thaiv colloid muaj zog tshaj plaws.
Kev Tsim Kho Kev Lag Luam: HEC tuaj yeem siv los ua tus neeg saib xyuas cov dej noo thiab cov cement chaw inhibitor.
Roj Drilling Kev Lag Luam: Nws tuaj yeem siv los ua cov thickener thiab cementing tus neeg sawv cev rau cov dej ua haujlwm zoo. Cov kua dej drilling nrog HEC tuaj yeem txhim kho kev ruaj ntseg zoo raws li nws cov ntsiab lus tsis muaj zog.
Txheej Kev Lag Luam: HEC tuaj yeem ua lub luag haujlwm hauv thickening, emulsifying, dispersing, stabilizing thiab khaws dej rau cov ntaub ntawv latex. Nws yog tus cwj pwm los ntawm qhov tseem ceeb thickening nyhuv, zoo xim kis tau tus mob, tsim zaj duab xis, thiab cia stability.
Daim ntawv thiab Ink: Nws tuaj yeem siv los ua tus neeg sawv cev rau ntawm daim ntawv thiab daim ntawv, ua cov thickener thiab suspending tus neeg sawv cev rau cov dej hauv cov inks.
Cov Tshuaj Txhua Hnub: HEC yog ib qho kev ua yeeb yaj kiab zoo, cov nplaum nplaum, thickener, stabilizer thiab dispersant nyob rau hauv cov tshuaj zawv plaub hau, cov plaub hau txias, thiab tshuaj pleev ib ce.
Pob: 25 kgs / hnab los yog raws li koj thov.
Cia: Khaws ntawm qhov chaw muaj cua, qhuav.
Cov txheej txheem raug tshem tawm: International Standard.
