Cellulose ether yog hom polymer Nws muaj cov dej zoo solubility, thickening, coheseness thiab dej khaws cia cov khoom, yog li nws tau siv dav hauv ib puag ncig cov ntaub ntawv tsev. dav siv.
1. Cov yam ntxwv ntawm cov kws ua haujlwm cellulose
Cellulose ether yog ib tug polymer tsim los ntawm cov nroj tsuag cog tom qab muaj kev kho mob. Nws muaj cov yam ntxwv tseem ceeb hauv qab no:
Thickening: cellulose ether tuaj yeem ua kom nce viscosity ntawm kev daws teeb meem thiab kev tswj hwm thaum lub sijhawm tsim kho.
Dej khaws cia: Cellulose ether muaj solubility nyob rau hauv cov khoom siv, ncua kev txhim kho dej kom ua tau zoo ntawm cov ntaub ntawv tsim tsev.
Adhesion: Cellulose ether tuaj yeem txhim kho cov khoom nplaum ntawm lub tsev thiab cov khoom siv hauv paus thiab txhim kho cov khoom nplaum thiab txhim kho cov khoom nplaum.
Kev ruaj khov: Cellulose ether muaj tshuaj lom neeg zoo thiab tuaj yeem tswj nws cov khoom hauv ntau cov kua qaub thiab alkali ib puag ncig.
2. Daim ntawv thov ntawm cellulose muaj kev pab cuam tus neeg nyob hauv ib puag ncig cov ntaub ntawv tsim tsev
2.1 Cov ntaub ntawv phab ntsa
Ntawm cov ntaub ntawv phab ntsa, cov neeg hais txog cellulose feem ntau yog siv hauv cov khoom xws li Gypsum Board, qhuav cug thiab phab ntsa putty. Nws tuaj yeem txhim kho lub viscosity thiab dej khaws cia ntawm cov ntaub ntawv no, ua kom yooj yim ntawm kev ua haujlwm ntawm cov ntaub ntawv thaum lub sijhawm kev tsim kho thiab lawv lub zog tom qab kho tas.
Gypsum Board: hauv kev tsim cov gypsum board, cov neeg muaj kev pab ntawm cellulose tuaj yeem siv cov ntawv tsis txaus siab thiab cov nplaum ntawm Gypsum tom qab ua kom tawv nqaij tawv.
Cov caple qhuav: cellulose ether yog siv los ua cov tuab thiab dej-khaws cov tshuaj khib thiab fluhesion thaum lub sijhawm ua kom tawv nqaij tawv.
2.2 Cov Khoom Siv Hauv Tsev
Cov neeg muaj neeg nyob hauv cellulose tseem muaj dav siv nyob hauv cov ntaub ntawv hauv pem teb xws li kev coj tus kheej theem thiab pobzeb cov khoom nplaum. Lawv tuaj yeem txhim kho kom zoo dua lub fluidity thiab tus kheej-theem ntawm cov ntaub ntawv hauv pem teb thiab ua kom cov du canness thiab ruaj khov ntawm paving.
Kev Ntsuas Tus Kheej Ua Si: Cov nyhuv tuab ntawm cellulose ether tuaj yeem txhim kho cov kua hauv av hauv pem teb thiab txo qis cov huab cua npuas.
Pobzeb nplaum: nyob rau hauv cov nplais nplaum, cellulose ether txhim kho lub viscosity thiab tsis tshua swb, txhim kho kev tsim kho thiab ua tau zoo.
2.3 Cov Ntaub Ntawv Waterproof
Daim ntawv thov ntawm cellulose ether nyob rau hauv cov ntaub ntawv tsis muaj cov khoom siv hauv cov cement-raws li cov kua pleev. Nws tuaj yeem txhim kho cov kab viscosity thiab kev tso cai rau cov yeeb yaj kiab dej los ua cov yeeb yaj kiab ntau dua thiab tsis tshua muaj kev tiv thaiv kab ke, yog li txhim kho cov nyhuv dej.
Maas-boed Waterproof txheej: Cellulose ete, raws li kev ntxiv, ua kom yooj yim thiab khaws cov txheej txheem yooj yim, thiab txhim kho nws qhov kev ua haujlwm tsis yooj yim.
2.4 Lwm yam kev siv
Ntxiv rau cov ntawv thov cov lus qhia saum toj no, cov cellulose cov neeg muaj kev pab tseem siv nyob rau hauv cov ntaub ntawv rwb thaiv tsev, kev tsim cov nplaum thiab cov khoom siv sealing. Lawv lub xub ntiag tuaj yeem txhim kho cov khoom ua tau zoo tag nrho, tshwj xeeb yog cov khoom siv qias neeg hauv ib puag ncig, thiab txo cov tshuaj lom neeg ib puag ncig los ntawm kev hloov cov khoom siv phom sij.
Raws li cov khoom tseem ceeb polymer, cellulose ether tau siv ntau dua nyob rau hauv ib puag ncig cov ntaub ntawv hauv tsev. Nrog nws cov dej zoo heev, cov dej khaws cia, cov nplaum thiab ruaj khov ether, tab sis kuj txhawb kev tiv thaiv ib puag ncig cov txheej txheem ntawm kev tsim kho kev tsim kho. Nyob rau hauv txoj kev txhim kho yav tom ntej, nrog kev txhim kho ib puag ncig thiab thev naus laus zis ntawm cov ntaub ntawv muaj kev nyab xeeb hauv tsev neeg yuav muaj dav dav.
