Kev tuav dej siab tuaj yeem ua rau cov cement hydrated, ua kom muaj zog ntawm daim ntawv cog lus, thiab nyob rau tib lub sijhawm, nws tuaj yeem tsim kom muaj zog tensile thiab shear zog, zoo heev txhim kho kev tsim kho thiab txhim kho kev ua haujlwm.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) nyob rau hauv dej-resistant putty hmoov
Nyob rau hauv cov hmoov putty, cellulose ether mas plays lub luag hauj lwm ntawm dej tuav, bonding thiab lubrication, tsis txhob tawg thiab lub cev qhuav dej tshwm sim los ntawm cov dej ntau dhau, thiab nyob rau tib lub sij hawm txhim khu lub adhesion ntawm putty, txo cov sagging tshwm sim thaum lub sij hawm tsim kho, thiab ua kev tsim kho smoother.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) hauv plaster plaster series
Ntawm cov khoom lag luam gypsum, cellulose ether tsuas yog ua lub luag haujlwm ntawm cov dej tuav thiab lubrication, thiab tseem muaj qee yam kev cuam tshuam, uas daws cov teeb meem ntawm bulging thiab pib lub zog hauv kev tsim kho, thiab tuaj yeem ua haujlwm ntev.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) nyob rau hauv tus neeg saib xyuas interface
Nws yog tsuas yog siv los ua cov thickener, uas tuaj yeem txhim kho lub zog tensile thiab shear lub zog, txhim kho txheej txheej, txhim kho qhov adhesion thiab daim ntawv cog lus.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) nyob rau hauv sab nrauv phab ntsa rwb thaiv tsev mortar
Hauv cov khoom siv no, cellulose ether tsuas yog ua lub luag haujlwm ntawm kev sib txuas thiab ua kom lub zog, yog li cov xuab zeb yuav yooj yim rau lub tsho thiab txhim kho kev ua haujlwm. Nyob rau tib lub sij hawm, nws muaj cov nyhuv ntawm anti-sagging. Shrinkage thiab tawg tsis kam, txhim kho nto zoo, muaj zog daim ntawv cog lus.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) hauv pobzeb nplaum
Kev tuav dej siab tsis tas yuav tsum tau ntub dej ua ntej lossis ntub cov vuas thiab lub hauv paus, uas tuaj yeem txhim kho lawv cov kev sib raug zoo. Lub slurry tuaj yeem siv sijhawm ntev, zoo thiab sib xws, thiab yooj yim rau kev tsim kho. Nws kuj muaj cov dej noo zoo.
Daim ntawv thov ntawm hydroxypropyl methylcellulose (HPMC) nyob rau hauv tus neeg sawv cev caulking thiab caulking tus neeg sawv cev
Qhov sib ntxiv ntawm cellulose ether ua rau nws muaj kev sib raug zoo ntawm ntug, tsis tshua muaj shrinkage thiab siab hnav tsis kam, uas tiv thaiv cov khoom siv los ntawm kev puas tsuaj thiab tsis txhob cuam tshuam ntawm kev nkag mus rau tag nrho lub tsev.
Kev siv hydroxypropyl methylcellulose (HPMC) hauv cov khoom siv tus kheej
Lub ruaj khov cohesiveness ntawm cellulose ether ua kom zoo fluidity thiab nws tus kheej-leveling peev xwm, thiab kev tswj ntawm cov dej tuav enables sai solidification, txo cracking thiab shrinkage.
