Daim Ntawv Thov Hydroxypropyl Methyl Cellulose Hauv Cov Khoom Siv Hauv Tsev

1. Tus nqi ntawm hydroxypropyl methyl cellulose
Hydroxypropyl methylcellulose (HPMC)yog ib qho cellulose ether uas tsis yog ionic ua los ntawm cov khoom siv polymer cellulose ntuj los ntawm ntau yam kev ua tshuaj lom neeg. Hydroxypropyl methylcellulose (HPMC) yog ib qho hmoov dawb tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom uas tuaj yeem yaj rau hauv dej txias los ua cov kua nplaum pob tshab. Nws muaj cov yam ntxwv ntawm kev ua kom tuab, kev nplaum, kev tawg, kev sib xyaw, kev tsim zaj duab xis, kev ncua, kev nqus, kev sib xyaw, kev ua haujlwm ntawm qhov chaw, kev khaws cia noo noo thiab kev tiv thaiv colloid.

2. Lub hom phiaj tseem ceeb ntawm Hydroxypropyl methylcellulose (HPMC) yog dab tsi?

HPMC siv dav hauv cov ntaub ntawv siv hauv kev tsim kho, tshuaj pleev xim, cov khoom siv ua los ntawm cov khoom siv av nplaum, tshuaj, khoom noj, ntaub, kev ua liaj ua teb, tshuaj pleev ib ce, luam yeeb thiab lwm yam lag luam. HPMC muaj peev xwm muab faib ua qib tsim kho, qib zaub mov thiab qib kho mob raws li nws lub hom phiaj. Tam sim no, feem ntau cov khoom hauv tsev yog qib tsim kho. Hauv qib tsim kho, hmoov putty siv ntau heev, kwv yees li 90% siv rau hmoov putty, thiab qhov seem siv rau cov cement mortar thiab kua nplaum.

3. Daim ntawv thov ntawmHydroxypropyl Methyl Cellulosehauv Cov Khoom Siv Hauv Tsev

1. ) Cov pob zeb masonry thiab cov pob zeb plastering

Yog tias cov cement tuav dej tau zoo, nws yuav ua rau cov cement noo tag. Qhov no yuav ua rau lub zog sib txuas ntawm cov cement nce ntxiv ntau heev. Tib lub sijhawm, nws yuav ua rau lub zog tensile thiab lub zog shear zoo dua. Qhov no yuav ua rau kev tsim kho zoo dua thiab ua rau kev ua haujlwm zoo dua.

2.) Cov dej tsis kam

Lub luag haujlwm tseem ceeb ntawm cellulose ether hauv putty yog khaws dej, nplaum thiab lubrication, kom tsis txhob poob dej ntau dhau ua rau tawg lossis tshem tawm hmoov, thiab tib lub sijhawm ua kom cov nplaum ntawm putty, txo qhov tshwm sim sagging thaum lub sijhawm tsim kho, thiab ua rau kev tsim kho du. Yooj yim.

3.) Tus neeg sawv cev sib txuas lus

Feem ntau siv ua cov khoom ua kom tuab, nws tuaj yeem txhim kho lub zog tensile thiab lub zog shear, txhim kho cov txheej txheem saum npoo, thiab txhim kho qhov adhesion thiab bonding zog.

4.) Cov tshuaj nplaum rwb thaiv tsev sab nraud

Cellulose ether ua lub luag haujlwm tseem ceeb hauv kev sib txuas thiab ua kom muaj zog ntxiv rau cov khoom siv no, ua rau cov mortar yooj yim rau txheej, txhim kho kev ua haujlwm zoo, thiab muaj peev xwm tiv thaiv kev dai. Kev ua tau zoo dua ntawm kev khaws dej tuaj yeem ua rau lub sijhawm ua haujlwm ntawm cov mortar ntev dua thiab txhim kho kev tiv thaiv kev ntsws thiab kev tawg, txhim kho qhov zoo ntawm qhov chaw, thiab ua kom muaj zog ntxiv.

5) Cov nplaum pobzeb

Qhov kev khaws dej tau zoo ua rau tsis tas yuav tsum tau ntub lossis ntub cov vuas thiab cov khoom siv ua ntej, uas tuaj yeem txhim kho lub zog sib txuas. Cov slurry tuaj yeem tsim tau ntev, mos, sib npaug, yooj yim tsim, thiab muaj cov yam ntxwv zoo tiv thaiv kev plam.

6. ) Tus neeg sawv cev caulking

Qhov ntxiv ntawm cellulose ether ua rau nws muaj qhov zoo ntawm ntug adhesion, qis shrinkage thiab siab abrasion tsis kam, tiv thaiv cov khoom siv los ntawm kev puas tsuaj kho tshuab, thiab zam kev cuam tshuam tsis zoo ntawm dej nkag mus rau tag nrho lub tsev.

7.) Cov khoom siv tus kheej

Qhov viscosity ruaj khov ntawm cellulose ether ua kom muaj kev fluidity zoo thiab muaj peev xwm tswj tus kheej, thiab tswj qhov ceev ntawm kev khaws dej kom ua rau cov khoom khov sai thiab txo qhov tawg thiab ntsws.
