Daim ntawv thov HPMC hauv cov ntaub ntawv tsim tsev

HydroxyPropyyl methylcellueculose (HPMC) yog qhov siv dav ntxiv hauv cov ntaub ntawv hauv tsev vim nws cov khoom tshwj xeeb. Nov yog qee cov kev siv ntawm HPMC hauv kev tsim kho kev tsim kho:

1. Pobzeb Adhesives thiab Grouts: HPMC feem ntau ntxiv rau cov nplaum nplaum thiab cov grouts los txhim kho lawv cov haujlwm, dej khaws cia, khoom qhib. Nws pab tiv thaiv kev tawm tsam sagging lossis cov nplais uas tsis muaj zog, ua kom muaj kev pheej hmoo ntawm cov kev pheej hmoo ntawm shrinkage cracks.
2. Mortars thiab Renders: HPMC yog siv rau hauv cov xis nyob hauv kev sib deev thiab cov ris tsho ua kom zoo dua los txhim kho lawv cov haujlwm, cohesion, dej khaws cia, thiab cov nplaum kom ua rau substrates. Nws txhim kho qhov sib xws thiab kev sib txuas ntawm cov dej txaws, thiab txhim kho cov sib khi ntawm cov tshuaj khib thiab lub substrate.
3. Plasters thiab Stucco: HPMC ntxiv rau plasters thiab stucco tsim qauv los tswj lawv cov khoom siv hluav taws xob, txhim kho kev ua haujlwm, thiab txhim kho adhesion. Nws pab tiv thaiv kom tawg, txhim kho saum npoo ua tiav, thiab txhawb kev sib dhos kom qhuav thiab kho cov plaster lossis stucco.
4. Gypsum khoom: HPMC yog siv rau hauv gypsum-based khoom xws li kev sib koom ua ke, thiab gypsum plasters los txhim kho lawv li kev sib xws, ua haujlwm, thiab cov tshuaj nplaum. Nws pab txo cov hmoov av, txhim kho sandability, thiab txhim kho txoj kev sib khi ntawm gypsum thiab substrate.
5. Kev Ntsuas Tus Kheej: HPMC ntxiv rau kev ua kom tus kheej-leveling los txhim kho lawv cov khoom ntws, muaj peev xwm los ntawm tus kheej, thiab kev ua tiav. Nws pab tiv thaiv kev sib cav sib ceg, txo qis los ntshav thiab shrinkage, thiab txhawb nqa kev tsim ntawm tus du, qib deg.
6. Kev rwb sab nrauv thiab cov tshuab tas (EIFS): HPMC yog siv los txhim kho cov nplaum, thiab lubricability ntawm lub system. Nws txhim kho daim ntawv cog lus ntawm lub rwb thaiv tsev pawg thawj coj thiab lub substrate, txo kev tawg, thiab txhim kho huab cua tsis kam ntawm lub tsho tiv no ua tiav.
7. Kev sib txuas Maas yog cov khoom sib txuas ua ke: HPMC ntxiv rau cov pob qij txha sib txuas los txhim kho lawv cov haujlwm, cov nplaum, thiab tawg tawm. Nws pab txo cov shrinkage, txhim kho feathering, thiab txhawb nqa kev du, ua tiav.
8. Txau-thov cov hluav taws xob: HPMC yog siv hauv cov khoom siv tshuaj txau los txhim kho lawv cov cohesion, adhesion, thiab kev tsis muaj zog. Nws pab tswj cov kev ncaj ncees thiab tuab ntawm cov txheej hluav taws xob, txhim kho cov nyiaj hauv lub zog rau lub substrate, thiab txo cov plua plav thiab rov qab ua haujlwm.

HPMC ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua tau zoo, kev ua haujlwm, thiab kav ntev ntawm ntau lub tsev cov ntaub ntawv siv. Nws siv ua rau muaj kev cog lus rau kev tsim cov khoom zoo, txhim khu kev qha, thiab cov khoom lag luam hauv tsev ntev rau ob qho chaw nyob thiab ua lag luam kev ua haujlwm.
