Cellulose ether yog ib qho tseem ceeb chemical additive uas feem ntau siv hauv cov khoom siv hauv tsev, thiab nws qhov zoo muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm thiab kev zoo ntawm mortar. Hauv kev tsim kho kev lag luam, kev ua tau zoo ntawm mortar muaj xws li kev ua haujlwm zoo, tsim nyog adhesion, dej tuav tau zoo thiab kev ua haujlwm tawg. Cov yam ntxwv ntawm cellulose ether ncaj qha cuam tshuam rau cov khoom no, yog li nws tuaj yeem hais tias qhov zoo ntawm cellulose ether txiav txim siab qhov zoo ntawm mortar mus rau qhov loj.
1. Kev tuav dej
Cellulose ether muaj cov dej tuav tau zoo, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm mortar thaum tsim kho. Cov khib nyiab nrog cov dej tuav tau zoo tuaj yeem khaws cov dej txaus thaum lub sij hawm cement hydration thiab tiv thaiv dej los ntawm evaporating sai heev, yog li ua kom lub zog thiab adhesion ntawm lub mortar. Tsis tas li ntawd, kev tuav dej zoo kuj tseem tuaj yeem tiv thaiv cov khib nyiab tawg los ntawm kev poob dej sai heev. Qhov zoo ntawm cellulose ether ncaj qha cuam tshuam rau nws lub peev xwm tuav dej, thiab cov cellulose ether zoo tuaj yeem muab cov dej tuav tau zoo dua.
2. Thickening nyhuv
Cov nyhuv thickening ntawm cellulose ether tuaj yeem ua rau kom cov viscosity ntawm mortar, yog li txhim kho kev ua haujlwm thiab kev tiv thaiv sagging ntawm mortar. Kev ua haujlwm tau hais txog qhov yooj yim ntawm kev sib xyaw, tso thiab ua kom lub ntsej muag ntawm cov mortar, uas yog ncaj qha ntsig txog kev ua haujlwm ntawm kev tsim kho thiab cov nyhuv tom qab kev tsim kho. Cov khoom zoo ntawm cov cellulose ether tuaj yeem muab cov nyhuv thickening ruaj khov, yog li cov mortar tsis yooj yim rau sag thaum lub sij hawm tsim kho thiab tswj cov kev tsim kho zoo.
3. Lubrication
Cellulose ether plays lub luag haujlwm lubricating hauv mortar, uas tuaj yeem txo kev sib txhuam thiab txhim kho cov kua dej ntawm cov mortar. Qhov no tuaj yeem ua rau cov mortar yooj yim dua rau kev sib kis thiab compact, txo qhov tsis muaj qhov sib piv, thiab txhim kho qhov ntom thiab lub zog ntawm cov mortar. Cov khoom zoo ntawm cov cellulose ether tuaj yeem muab cov khoom zoo lubrication, ua rau cov mortar yooj yim rau kev khiav lag luam thiab txhim kho kev tsim kho kom zoo.
4. ncua sij hawm teem caij
Cellulose ether tuaj yeem tsim kho lub sijhawm teem sijhawm ntawm mortar thiab muab sijhawm txaus rau kev tsim kho. Tshwj xeeb tshaj yog nyob rau hauv loj-scale kev tsim kho los yog complex vaj tse, lub sij hawm ncua sij hawm yuav muab sij hawm rau cov neeg ua hauj lwm tsim kho thiab kho kom zoo. Cov cellulose ether zoo tuaj yeem tswj lub sijhawm teem sijhawm kom tsis txhob muaj teeb meem kev tsim kho los ntawm kev teeb tsa ntxov lossis lig.
5. Kev tiv thaiv tawg
Cellulose ether tuaj yeem txo qhov tshwm sim ntawm cov kab nrib pleb shrinkage los ntawm kev txhim kho cov dej tuav thiab toughness ntawm mortar. Cov kab nrib pleb shrinkage yog tshwm sim los ntawm qhov ntim ntim vim qhov evaporation ntawm cov dej hauv mortar, uas cuam tshuam rau kev ua haujlwm ntev thiab kev zoo nkauj ntawm lub tsev. Qhov zoo ntawm cellulose ether tuaj yeem txhim kho qhov tawg ntawm cov tshuaj khib thiab txo tus nqi ntawm kev kho tom qab thiab kho.
6. Environmental adaptability
Qhov kev ua tau zoo ntawm mortar yuav raug cuam tshuam nyob rau hauv ib puag ncig sib txawv. Qhov zoo ntawm cellulose ether yuav cuam tshuam rau nws txoj kev ruaj ntseg nyob rau hauv huab cua txias xws li kub, tsis kub, thiab high humidity. Cov khoom zoo ntawm cellulose ether tuaj yeem tswj tau qhov kev ua tau zoo nyob rau hauv ntau qhov chaw ib puag ncig, ua rau cov mortar siv tau ntau dua.
Qhov zoo ntawm cellulose ether muaj feem cuam tshuam rau kev ua haujlwm ntawm mortar. Qhov zoo ntawm cellulose ether tuaj yeem txhim kho cov dej tuav, kev ua haujlwm, kev ua haujlwm tawg thiab kev siv cov tshuaj khib nyiab, yog li txhim kho qhov zoo thiab ua haujlwm ntawm kev tsim kho. Yog li ntawd, thaum xaiv thiab siv mortar, nws yog ib qho tseem ceeb heev los xyuas kom meej qhov zoo ntawm cellulose ether, uas yuav ncaj qha cuam tshuam rau qhov zoo ntawm qhov kawg siv nyhuv.
