Hydroxypropylmethylcellulose (HPMC) yog ib qho hmoov dawb uas tsis muaj ntxhiab, tsis muaj tshuaj lom, uas tuaj yeem yaj rau hauv dej txias kom tsim tau cov kua dej uas pom tseeb. Nws muaj cov yam ntxwv ntawm kev ua kom tuab, kev sib txuas, kev tawg, emulsification, demulsification, floating, adsorption, adhesion, surface activity, moisturizing, thiab kev txij nkawm colloidal.
1. Cov kua qaub ntsuab cement mortar
Qhov uas cov dej khaws cia tau zoo ua rau cov pob zeb khov kho tag. Lub zog compressive ntawm cov ntawv cog lus txuas ntxiv nce ntxiv. Tsis tas li ntawd, lub zog tensile thiab shear tuaj yeem nce ntxiv. Txhim kho qhov cuam tshuam tiag tiag ntawm kev tsim kho thiab txhim kho kev ua haujlwm zoo.
2. Cov dej tsis haum
Lub luag haujlwm tseem ceeb ntawm cellulose ether hauv cov hmoov putty yog kom tswj tau cov dej noo, sib txuas thiab roj, tiv thaiv kom tsis txhob muaj kab nrib pleb lossis kua nplaum qhib vim muaj dej ntau dhau, txhim kho kev sib koom ua ke ntawm cov hmoov putty, thiab txo qhov xwm txheej ntawm qhov chaw tsim kho. Ua kom qhov project tsim kho zoo dua thiab txuag peev txheej tib neeg.
3. Tus neeg sawv cev sib txuas lus
Feem ntau ua ib qho emulsifier, nws tuaj yeem ua rau lub zog thiab lub zog tensile nce ntxiv, txhim kho qhov txheej txheem saum npoo, thiab txhim kho qhov adhesion thiab bonding zog.
4. Cov tshuaj nplaum rwb thaiv tsev phab ntsa sab nraud
Cellulose ether ua lub luag haujlwm tseem ceeb hauv kev sib txuas, txhim kho lub zog, ua rau cov cement mortar yooj yim rau txheej, thiab txhim kho kev ua haujlwm. Ua kom lub sijhawm ua haujlwm ntev dua, txhim kho kev tiv thaiv kev ntsws thiab kev sib koom ua ke ntawm cov cement mortar, txhim kho kev ua haujlwm ntawm cov txheej txheem, thiab ua kom lub zog sib txuas ntawm cov khoom sib txuas.
5. Cov kua nplaum pobzeb
Cov khoom siv dej zoo tsis tas yuav tsum tau ntub ua ntej lossis ntub cov vuas ceramic thiab cov khoom siv hauv qab, uas tuaj yeem txhim kho lawv lub zog sib txuas. Cov mortar siv tau ntev, zoo, sib npaug zoo, yooj yim rau kev tsim kho, thiab muaj cov khoom tiv thaiv kev plam zoo.
6. tus neeg sawv cev caulking taw qhia tus neeg sawv cev
Qhov ntxiv ntawm cellulose ether muaj qhov nplaum zoo ntawm ntug, qis shrinkage thiab siab hnav tsis kam, tiv thaiv cov ntaub ntawv yooj yim los ntawm kev puas tsuaj rau cov khoom siv kho tshuab, thiab zam kev cuam tshuam tsis zoo ntawm kev nkag mus rau hauv dej rau tag nrho lub tsev.
7. Cov ntaub ntawv raw khoom uas nws tus kheej siv tau
Qhov viscosity ruaj khov ntawm cellulose ether ua kom muaj qhov zoo fluidity thiab tus kheej-leveling peev xwm ntawm cellulose ether, tswj cov dej khaws cia tus nqi, ua rau cellulose ether khov sai, thiab txo cov kab nrib pleb thiab shrinkage.
