Hydroxypropyl methylcellulose yog ib qho uas tsis yog-ionic cellulose ether tau los ntawm cov paj rwb refined, ib yam khoom siv polymer, los ntawm ntau cov txheej txheem tshuaj. Feem ntau siv nyob rau hauv kev tsim kho kev lag luam: dej-resistant putty hmoov, putty paste, tempered putty, xim kua nplaum, masonry plastering mortar, qhuav hmoov rwb thaiv tsev mortar thiab lwm yam qhuav hmoov tsev ntaub ntawv.
Hydroxypropyl methylcellulose muaj cov dej tuav zoo, yooj yim rau kev thov, thiab muaj ntau yam viscosities xaiv los ntawm, uas tuaj yeem ua tau raws li ntau yam kev xav tau.
Hydroxypropyl methylcellulose ether nrog kev ua tau zoo tuaj yeem txhim kho kev tsim kho kev ua tau zoo, siv thiab txau cov tshuaj khib nyiab, thiab yog ib qho tseem ceeb ntxiv hauv mortar.
1. Hydroxypropyl methyl cellulose ether muaj cov dej tuav tau zoo heev thiab yog siv dav hauv ntau yam mortars, nrog rau cov tshuaj txhuam hniav, plastering mortars thiab hauv av leveling mortars, los txhim kho cov ntshav ntawm cov mortars.
2. Hydroxypropyl methyl cellulose ether muaj cov nyhuv thickening, txhim kho kev tsim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov mortar, hloov cov fluidity ntawm cov khoom, ua tiav cov nyhuv yam xav tau, thiab ua rau kom puv thiab siv ntim ntawm cov tshuaj khib nyiab.
3. Vim tias hydroxypropyl methyl cellulose ether tuaj yeem txhim kho kev sib koom ua ke thiab kev ua haujlwm ntawm mortar, nws kov yeej cov teeb meem xws li plhaub thiab hollowing ntawm mortar zoo tib yam, txo qhov blanking, txuag cov ntaub ntawv, thiab txo cov nqi.
4. Hydroxypropyl methyl cellulose ether muaj cov nyhuv retarding, uas tuaj yeem ua kom lub sijhawm ua haujlwm ntawm cov mortar thiab txhim kho cov yas thiab kev tsim kho ntawm cov tshuaj khib nyiab.
5. Hydroxypropyl methyl cellulose ether tuaj yeem ua kom pom cov pa npuas kom tsim nyog, uas tuaj yeem txhim kho cov tshuaj tiv thaiv kev ua haujlwm ntawm cov tshuaj khib nyiab thiab txhim kho lub zog ntawm cov mortar.
6. Cellulose ether plays lub luag hauj lwm ntawm dej tuav thiab thickening los ntawm kev sib txuas ntawm lub cev thiab tshuaj. Thaum lub sij hawm hydration txheej txheem, nws muaj peev xwm tsim cov khoom uas ua rau micro-expansion zog, thiaj li hais tias lub mortar muaj ib tug tej yam micro-expansion khoom thiab tiv thaiv lub mortar los ntawm hydration nyob rau hauv lub tom ntej theem. Kev tawg ua los ntawm shrinkage nyob rau hauv nruab nrab nce lub neej kev pab cuam ntawm lub tsev.
