Lub luag haujlwm ntawm hydroxypropyl methylcellulose hauv mortar

Hydroxypropylmethylcellulose

Ntau tshaj 95% ntawm kev tsim kho-qibHydroxypropyl methylcellulose yog tsim los ntawm cov tshuajyog siv nyob rau hauv putty hmoov mortar. Nws cov haujlwm yog thickening, dej tuav thiab kev tsim kho. Kev tuav dej ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab daim ntawv thov, txhim khu lub zog tom qab hardening, lub luag haujlwm tseem ceeb yog dej tuav, thickening, thiab los tiv thaiv sagging. Nws tuaj yeem siv los ua cov nplaum hauv plaster, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev los txhim kho kev sib kis thiab ua haujlwm ntev; xws li cov vuas luaj ceramic, marble, plastics Kho kom zoo nkauj: Raws li cov tshuaj pleev ib ce, nws tuaj yeem txo cov cement; rau cov tshuaj tiv thaiv kev sib tsoo, ntxiv qee cov polypropylene anti-crack fiber (PP fiber) hauv qhov tsim nyog, kom lawv muaj nyob rau hauv daim ntawv ntawm barbs hauv mortar, thiaj li ua tiav cov nyhuv anti-crack. HPMC tsuas yog ua lub luag haujlwm ntawm dej tuav, thickening thiab anti-sag.

1. Kev tsim kho mortar plastering mortar

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.

2. Water-resistant putty

Hauv putty, hydroxypropyl methylcellulose cellulose ether tsuas yog ua lub luag haujlwm ntawm kev tuav dej, kev sib txuas thiab lubrication, tsis txhob tawg thiab lub cev qhuav dej los ntawm dej ntau dhau, thiab tib lub sij hawm txhim kho qhov adhesion ntawm putty thiab txo qis sag thaum lub sij hawm tsim kho Phenomenon, thiaj li hais tias kev tsim kho yog du.

3. Plaster plaster series

Ntawm cov khoom lag luam gypsum, hydroxypropyl methylcellulose cellulose ether tsuas yog ua lub luag haujlwm ntawm cov dej tuav thiab lubrication, thiab tib lub sijhawm muaj qee qhov cuam tshuam, uas daws cov teeb meem ntawm lub nruas tawg thiab pib lub zog tsis ua haujlwm thaum lub sijhawm tsim kho, thiab tuaj yeem txuas ntxiv sijhawm ua haujlwm.

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 cov txheej txheej saum npoo, txhim kho qhov adhesion thiab kev sib txuas lub zog.

5. Sab nrauv phab ntsa rwb thaiv tsev mortar

Hauv cov khoom siv no, hydroxypropyl methylcellulose cellulose ether tsuas yog ua lub luag haujlwm ntawm kev sib txuas thiab ua kom muaj zog, ua rau nws yooj yim rau cov tshuaj khib thiab txhim kho kev ua haujlwm. Ua kom lub sij hawm ua hauj lwm ntawm mortar, txhim kho shrinkage thiab tawg kuj, txhim kho nto zoo, thiab ua kom muaj zog daim ntawv cog lus.

6. Cov nplaum nplaum

Kev tuav dej siab tsis tas yuav tsum tau ntub dej ua ntej los yog ntub cov vuas thiab lub hauv paus, uas tuaj yeem txhim kho lawv txoj 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.

7, tus neeg sawv cev caulk, tus neeg sawv cev taw qhia

Qhov ntxiv ntawmhydroxypropyl methylcellulose cellulose etherua 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 zam kev puas tsuaj los ntawm kev nkag mus rau tag nrho lub tsev. Kev npam.
