Hydroxypropyl methylcellulose yog cov cellulose ether uas tsis yog ionic tau los ntawm paj rwb zoo, ib yam khoom siv polymer ntuj, los ntawm ntau yam txheej txheem tshuaj lom neeg. Feem ntau siv rau hauv kev lag luam kev tsim kho: hmoov putty uas tiv taus dej, hmoov putty, putty tempered, kua nplaum xim, mortar plastering, mortar rwb thaiv tsev hmoov qhuav thiab lwm yam khoom siv hmoov qhuav.
Hydroxypropyl methylcellulose muaj cov dej zoo khaws cia, yooj yim siv, 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 ua tau zoo ntawm kev tsim kho, kev nqus dej thiab kev txau ntawm cov tshuaj khib, thiab yog ib qho tseem ceeb ntxiv rau hauv cov tshuaj khib.
1. Hydroxypropyl methyl cellulose ether muaj kev ua tau zoo heev ntawm kev khaws dej thiab siv dav hauv ntau yam mortars, suav nrog masonry mortars, plastering mortars thiab av leveling mortars, los txhim kho cov ntshav ntawm mortars.
2. Hydroxypropyl methyl cellulose ether muaj cov nyhuv thickening tseem ceeb, txhim kho kev ua haujlwm ntawm kev tsim kho thiab kev ua haujlwm ntawm cov mortar, hloov pauv qhov fluidity ntawm cov khoom, ua tiav qhov zoo li xav tau, thiab ua rau kom puv thiab siv ntim ntawm cov mortar.
3. Vim tias hydroxypropyl methyl cellulose ether tuaj yeem txhim kho qhov kev sib koom ua ke thiab kev ua haujlwm ntawm cov mortar, nws kov yeej cov teeb meem tshwm sim xws li kev plhaub thiab hollowing ntawm cov mortar ib txwm muaj, txo qhov blanking, txuag cov ntaub ntawv, thiab txo cov nqi.
4. Hydroxypropyl methyl cellulose ether muaj qee yam kev cuam tshuam, uas tuaj yeem ua kom lub sijhawm ua haujlwm ntawm cov mortar thiab txhim kho qhov plasticity thiab kev tsim kho ntawm cov mortar.
5. Hydroxypropyl methyl cellulose ether tuaj yeem ua rau muaj cov npuas cua zoo, uas tuaj yeem txhim kho qhov ua tau zoo ntawm cov tshuaj khib nyiab thiab txhim kho qhov ruaj khov ntawm cov tshuaj khib nyiab.
6. Cellulose ether ua lub luag haujlwm ntawm kev khaws dej thiab ua kom tuab los ntawm kev sib xyaw ua ke ntawm cov teebmeem ntawm lub cev thiab tshuaj lom neeg. Thaum lub sijhawm ua kom dej noo, nws tuaj yeem tsim cov tshuaj uas ua rau muaj cov yam ntxwv me me, yog li cov mortar muaj qee yam khoom me me thiab tiv thaiv cov mortar los ntawm kev ua kom dej noo hauv theem tom qab. Qhov tawg los ntawm kev ntsws hauv nruab nrab ua rau lub neej ua haujlwm ntawm lub tsev ntev dua.
