Kev siv Hydroxypropyl Methyl Cellulose hauv Cov Khoom Siv Hauv Tsev

1. Tus nqi ntawm hydroxypropyl methyl cellulose
Hydroxypropyl methylcellulose (HPMC)yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm tej yam ntuj tso polymer khoom cellulose los ntawm ib tug series ntawm tshuaj ua. Hydroxypropyl methylcellulose (HPMC) yog cov hmoov tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom cov hmoov dawb uas tuaj yeem yaj hauv dej txias los tsim cov kua nplaum pob tshab. Nws muaj cov yam ntxwv ntawm thickening, adhesion, dispersion, emulsification, zaj duab xis tsim, ncua kev kawm ntawv, adsorption, gelation, deg kev ua si, noo noo retention thiab tiv thaiv colloid.

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

HPMC yog dav siv nyob rau hauv cov khoom siv, coatings, hluavtaws resins, ceramics, tshuaj, khoom noj khoom haus, textiles, ua liaj ua teb, tshuaj pleev ib ce, luam yeeb thiab lwm yam lag luam. HPMC tuaj yeem muab faib ua qib kev tsim kho, qib zaub mov thiab qib kho mob raws li nws lub hom phiaj. Tam sim no, feem ntau cov khoom siv hauv tsev yog qib kev tsim kho. Nyob rau hauv kev tsim kho qib, putty hmoov yog siv ntau npaum li cas, li 90% yog siv rau putty hmoov, thiab tus so yog siv rau cement mortar thiab kua nplaum.

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

1.) Masonry mortar thiab plastering mortar

Kev tuav dej siab tuaj yeem ua kom cov cement tag nrho. Qhov tseem ceeb nce lub zog ntawm daim ntawv cog lus. Nyob rau tib lub sijhawm, nws tuaj yeem tsim kho lub zog tensile thiab shear lub zog. Txhim kho kev tsim kho zoo heev thiab ua kom muaj kev ua haujlwm zoo.

2.) Waterproof putty

Lub luag haujlwm tseem ceeb ntawm cellulose ether hauv putty yog dej tuav, adhesion thiab lubrication, kom tsis txhob poob dej ntau dhau ua rau tawg lossis hmoov tshem tawm, thiab tib lub sijhawm ua kom cov adhesion ntawm putty, txo cov sagging tshwm sim thaum lub sij hawm tsim kho, thiab ua kom kev tsim kho smoother. Tsis siv zog.

3.) Tus neeg saib xyuas interface

Feem ntau yog siv los ua cov thickener, nws tuaj yeem txhim kho lub zog tensile thiab shear lub zog, txhim kho cov txheej txheej saum npoo, thiab txhim kho cov adhesion thiab kev sib txuas lub zog.

4.) Sab nraud thermal rwb thaiv tsev mortar

Cellulose ether plays lub luag haujlwm tseem ceeb hauv kev sib txuas thiab ua kom muaj zog hauv cov khoom siv no, ua rau cov tshuaj khib nyiab yooj yim dua, txhim kho kev ua haujlwm, thiab muaj peev xwm tiv thaiv dai. Kev tuav dej ntau dua tuaj yeem txuas ntxiv lub sijhawm ua haujlwm ntawm cov mortar thiab txhim kho kev tiv thaiv shrinkage thiab Crack tsis kam, txhim kho nto zoo, thiab ua kom muaj zog sib txuas.

5) Pobzeb nplaum

Kev tuav dej siab tshem tawm qhov xav tau ua ntej-so los yog ntub cov vuas thiab substrates, uas tuaj yeem txhim kho kev sib raug zoo. Lub slurry tuaj yeem tsim nyob rau lub sijhawm ntev, muag heev, zoo ib yam, yooj yim rau kev tsim, thiab muaj cov khoom zoo los tiv thaiv plam.

6.) Caulking agent

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

7.) Cov khoom siv tus kheej qib

Qhov ruaj khov viscosity 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.
