Hydroxypropyl methylcellulose yog sivyog ib qho khoom siv raw khoom hauv kev lag luam chemical. Hauv kev tsim khoom txhua hnub, peb tuaj yeem hnov nws lub npe. Tab sis ntau tus neeg tsis paub nws siv. Niaj hnub no, kuv yuav piav qhia txog kev siv hydroxypropyl methylcellulose hauv ntau qhov chaw.
1. Kev tsim kho mortar, plastering mortar
Raws li tus neeg saib xyuas dej-retaining thiab retarder rau cov cement mortar, nws tuaj yeem txhim kho lub twj tso kua mis ntawm cov mortar, txhim kho kev sib kis thiab ua kom lub sijhawm ua haujlwm ntev. Cov dej tuav ntawm HPMC tuaj yeem tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening.
2. Water-resistant putty
Nyob rau hauv lub putty, cellulose ether feem ntau 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 qhov tshwm sim ntawm sagging thaum lub sij hawm tsim kho, thiab ua. txoj kev tsim kho smoother.
3. Plaster plaster
Hauv cov khoom lag luam gypsum, cellulose ether tsuas yog ua lub luag haujlwm ntawm cov dej tuav, thickening thiab lubrication, thiab muaj qee yam cuam tshuam rau tib lub sijhawm, uas daws qhov teeb meem ntawm qhov tsis tuaj yeem pib lub zog thaum lub sijhawm tsim kho, thiab tuaj yeem ua haujlwm ntev.
4. Tus neeg saib xyuas interface
Feem ntau siv los ua cov thickener, nws tuaj yeem txhim kho lub zog tensile thiab shear lub zog, txhim kho txheej txheej, txhim kho adhesion thiab daim ntawv cog lus.
5. Sab nrauv rwb thaiv tsev mortar rau sab nrauv phab ntsa
Cellulose ether tsuas yog ua lub luag haujlwm ntawm kev sib txuas thiab ua kom muaj zog hauv cov khoom siv no. Nws yog qhov yooj yim dua los npog cov xuab zeb, txhim kho kev ua haujlwm ntawm kev ua haujlwm, thiab muaj cov nyhuv los tiv thaiv sag ntws. Kev tuav dej ntau dua tuaj yeem ua rau lub sijhawm ua haujlwm ntawm cov tshuaj khib nyiab thiab txhim kho cov kev tiv thaiv Shrinkage thiab tawg tsis kam, txhim kho nto zoo, muaj zog daim ntawv cog lus.
6, tus neeg sawv cev caulk, ditch sib koom tus neeg sawv cev
Qhov sib ntxiv ntawm cellulose ether muab nws zoo ntug adhesion, tsawg shrinkage thiab siab abrasion tsis kam, uas tiv thaiv lub hauv paus cov ntaub ntawv los ntawm txhua yam kev puas tsuaj thiab tsis txhob muaj kev cuam tshuam ntawm kev nkag mus rau tag nrho lub tsev.
7. DC cov khoom tiaj tus
Qhov ruaj khov cohesiveness ntawm cellulose ether ua kom zoo fluidity thiab nws tus kheej-leveling muaj peev xwm, thiab tswj cov dej tuav tus nqi kom ceev ceev solidification thiab txo qhov tawg thiab shrinkage.
8. Latex xim
Hauv kev lag luam txheej, cellulose ethers tuaj yeem siv los ua zaj duab xis yav dhau los, thickeners, emulsifiers thiab stabilizers, kom cov yeeb yaj kiab muaj kev cuam tshuam zoo, qib, adhesion, thiab PH uas txhim kho qhov nro yog qhov zoo, cov miscibility nrog cov kuab tshuaj organic kuj zoo. , thiab kev tuav dej siab ua haujlwm ua rau nws muaj kev txhuam zoo thiab dej theem.
Kuv ntseeg tias txhua tus neeg muaj kev nkag siab txog hydroxypropyl methylcellulose. Raws li ib qho tseem ceeb raw khoom nyob rau hauv lub tsev cov ntaub ntawv kev lag luam tshuaj, hydroxypropyl methylcellulose cuam tshuam rau qhov zoo ntawm cov khoom downstream. Yog li ntawd, thaum xaiv hydroxypropyl methylcellulose, nco ntsoov ua kom koj lub qhov muag qhib. Tsuas yog cov khoom lag luam zoo tuaj yeem tsim cov khoom zoo.
