Kev khaws dej kom zoo dua tiv thaiv kev qhuav ua ntej ntawm cov khoom sib xyaw, cia lawv teeb tsa zoo dua thiab khi zoo rau cov substrates.
• Kev Ua Haujlwm Zoo Dua: Hauv cov ntaub ntawv siv hauv kev tsim kho xws li cov nplaum pobzeb, cov plasters, thiab cov grout, HEC ua rau kev ua haujlwm zoo dua. Los ntawm kev kho cov khoom rheological, nws ua kom du dua daim ntawv thov, txo qis sagging, thiab zoo dua adhesion, uas yog qhov tseem ceeb rau kev ua kom ruaj khov thiab zoo nkauj ntawm cov khoom kawg.
• Kev Tsim Zaj Duab Xis: HEC kuj ua haujlwm ua tus neeg sawv cev tsim zaj duab xis, uas yog qhov tshwj xeeb tshaj yog pab tau rau hauv cov txheej thiab xim. Cov polymer tsim cov zaj duab xis txuas ntxiv, sib koom ua ke, txhim kho qhov ruaj khov, tsos, thiab kev ua tau zoo ntawm cov txheej, thaum muab kev tiv thaiv zoo dua rau kev hnav thiab tsim kua muag.
• Tsis muaj tshuaj lom thiab ib puag ncig zoo: HEC tsis muaj tshuaj lom thiab tsis muaj cov kuab tshuaj lom, ua rau nws muaj kev nyab xeeb thiab ib puag ncig zoo rau ntau yam kev siv, tshwj xeeb tshaj yog cov khoom siv hauv kev tsim kho uas siv rau hauv qhov chaw kaw.

Cov ntawv thov ntawm Hydroxyethyl Cellulose hauv kev tsim kho

• Cov Nplaum Rau Pobzeb: Hauv kev tsim cov nplaum rau pobzeb, HEC ua kom cov khoom nplaum zoo dua los ntawm kev txhim kho qhov sib xws thiab khaws dej ntawm cov qauv. Lub sijhawm qhib zoo dua ua kom cov pobzeb tuaj yeem siv tau yooj yim yam tsis poob lawv lub zog sib txuas. HEC kuj tseem muab kev tiv thaiv kev plam zoo heev, tiv thaiv cov pobzeb kom tsis txhob txav thaum lub sijhawm teeb tsa.
• Cov Khoom Sib Xyaws Ua Los Ntawm Cement Thiab Mortar: HEC ua lub luag haujlwm tseem ceeb hauv cov qauv cement thiab mortar los ntawm kev txhim kho kev khaws dej thiab txhim kho kev ua haujlwm ntawm cov khoom sib xyaw. Nws pab tswj kom muaj qhov sib npaug ntawm cov dej noo thaum lub sijhawm kho, kom ntseeg tau tias cov mortar tsim kom muaj zog sib txuas zoo tshaj plaws.
• Cov Plasters thiab Putty: Thaum ntxiv rau cov plaster thiab putty formulations, HEC txhim kho qhov du thiab sib xws ntawm cov khoom, ua rau nws yooj yim dua rau kev nthuav dav thiab ua tiav. Cov polymer kuj pab tiv thaiv kev tawg los ntawm kev ua kom cov dej noo khaws cia, uas yog qhov tseem ceeb thaum lub sijhawm ziab thiab kho.
• Cov Tshuaj Pleev Xim Pob Zeb Thiab Cov Tshuaj Pleev Xim Cementitious: HEC siv rau hauv cov pob zeb thiab lwm cov tshuaj pleev xim cementitious los txhim kho viscosity thiab stability. Qhov no ua kom muaj kev siv du thiab sib xws thaum tseem txhim kho lub zog sib txuas thiab kev ywj pheej ntawm qhov chaw kawg.
