Raws li cov tsis yog-ionic surfactant, hydroxyethyl cellulose muaj cov khoom hauv qab no ntxiv, kev sib koom ua ke, dej tuav thiab muab cov kev tiv thaiv kev tiv thaiv. Hydroxyethyl cellulose (HEC Peb txhua tus paub tias ob qho hydroxyethyl cellulose hec thiab hydroxypropyl yog siv rau hauv cov khoom siv hauv tsev, tab sis dab tsi yog qhov sib txawv ntawm ob cov khoom siv raw?
Muaj ntau ntawm cov khaub ncaws cob qhia ntawm kev ua lag luam, muaj zog dej-resistant polymer patomers thiab lwm yam resin cov hmoov roj hmab thiab recispersible looj hmoov? Yuav tuaj yeem hloov cov hmoov hloov hluav taws xob redispersible looj hmoov?
Colleg yog lub tsev siv cov khoom siv nrog ntau ntawm kev siv thiab ntau yam kev siv hauv cov tuam tsev lag luam thiab pej xeem. Muaj ob daim ntawv ntawm chaw npaj thiab ua lag luam ntawm kev siv tshuaj. Tam sim no, kev ua lag luam ntawm kev ua haujlwm cug hauv cov teb chaws tsim hauv Tebchaws Europe thiab tau muaj siab heev. Qhov no yog vim hais tias qhuav-sib xyaw bagged los yog txiv kab ntxwv yuav ua rau lub sijhawm tsim kho ntawm lub chaw tsim kho thiab txo cov nqi ua haujlwm. Haum rau cov hauv paus thiab cov khoom sib txawv ntawm cov hom ntau yam txhim kho kom zoo thiab tiv thaiv ib puag ncig. Nyob rau hauv sib piv rau cov neeg nplua nuj uas tau sib xyaw ua ke, xws li cov khoom xyaw ua ke, xws li cov khoom siv tshuaj tsw qab, raws li cov khoom siv tshuaj ntsuab, raws li cov khoom siv tshuaj tsw qab rau cov khoom lag luam kom qhuav.
Muaj m ua tus neeg sawv cev kho rau drilling av nkos thiab cov kua dej yaug cov kua, nws tuaj yeem tawm tsam cov kuab paug ntawm ntau cov ntsev soluble. Cov av nkos muaj M tsis tshua muaj cuam tshuam los ntawm pwm, yog li nws tsis tsim nyog los tswj tus nqi pH siab thiab siv cov tshuaj txuag. Drilling av nkos thiab lwm cov kev ncua thiab kev faib tawm muaj qee yam txee lub neej, ntxiv m tuaj yeem ua kom nws ruaj khov thiab ntev lub txee lub neej.
Hydroxyethyl cellulose (HEC) yog cov tsis-ionic cellulose ither ua los ntawm cov ntaub ntawv polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm ntawm lub ntsej muag. Nws yog qhov tsis muaj ntxhiab, cov tsis tau muaj hmoov dawb lossis cov tshuaj nplaum dawb, uas tuaj yeem yog cov tshuaj tsis huv, thiab kev sib cais tsis cuam tshuam los ntawm tus nqi PH. Nws muaj cov yam ntxwv ntawm thickening, adhesion, kev sib cais, kev ua yeeb yaj kiab, kev ua yeeb yaj kiab, kev ua si saum npoo av, dej rov qab thiab ntsev tsis kam. Dav siv nyob rau hauv cov xim pleev xim, kev tsim kho, textile, tshuaj txhua hnub, ntawv, roj drilling thiab lwm yam lag luam.
Redispersible looj hmoov dej yog dej-solbonic copders, uas tau muab faib ua ethylene / vinyl acetate acid capolymers, thiab lwm yam. Cawv yog siv los ua kev tiv thaiv kev tiv thaiv. Qhov hmoov zoo no tuaj yeem redisperse sai sai rau hauv emulsion tom qab hu nrog dej. Vim yog lub peev xwm ua tau zoo thiab cov khoom muaj yeej ntawm cov hmoov av liab, xws li Rwb thaiv dej dej, thiab lwm yam kev thov cov qhab nia loj heev
