Kev siv Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl methylcellulose yog cov khoom siv raw hauv cov khoom siv tshuaj lom neeg hauv tsev. Hauv kev tsim khoom txhua hnub, peb tuaj yeem hnov ​​​​nws lub npe. Tab sis ntau tus neeg tsis paub nws siv. Hnub no, kuv yuav piav qhia rau koj txog kev sivHydroxypropyl methylcellulose yog ib qho khoom siv zoonyob rau hauv ib puag ncig sib txawv.

1. Kev tsim kho mortar, plastering mortar

Raws li tus neeg saib xyuas dej-retaining thiab retarder ntawm cov cement mortar, nws ua rau cov mortar pumpable, txhim kho kev siv tau thiab ua kom lub sijhawm ua haujlwm ntev. Kev ua haujlwm ntawm cov dej khaws cia ntawm HPMC 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 mas plays lub luag hauj lwm ntawm dej tuav, bonding thiab lubrication, tsis txhob muaj kab nrib pleb 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 rau lub adhesion ntawm lub putty. kev tsim kho smoother.

3. Xim plaster

Hauv cov khoom lag luam gypsum, cellulose ether tsuas yog ua lub luag haujlwm ntawm kev tuav dej, thickening, lubrication, thiab lwm yam, thiab 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. .

4. 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.

5. Sab nrauv rwb thaiv tsev mortar rau sab nrauv phab ntsa

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 kuj, txhim kho nto zoo, muaj zog daim ntawv cog lus.

6. Sealant, tus neeg sawv cev caulking

Qhov sib ntxiv ntawm cellulose ether ua rau nws muaj kev sib raug zoo ntawm ntug, qis 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.

7. DC cov khoom tiaj tus

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.

8. Latex xim

Hauv kev lag luam xim, cellulose ether tuaj yeem siv los ua tus neeg ua yeeb yaj kiab tsim, thickener, emulsifier thiab stabilizer, yog li cov yeeb yaj kiab muaj kev cuam tshuam zoo, cov cuab yeej qib siab, adhesion, thiab PH ntawm kev txhim kho qhov nro yog qhov zoo. , Cov miscibility nrog cov kuab tshuaj organic kuj zoo, thiab cov dej tuav tau zoo ua rau nws muaj kev txhuam zoo thiab ua kom zoo.
