wuxuu leeyahay dhaqdhaqaaq dusha sare ah, hufnaan sare iyo waxqabad deggan.
Hydroxypropyl methyl cellulose, oo sidoo kale loo yaqaan hydroxypropyl methyl cellulose, xirmada fiber hydroxypropyl methyl ether, waa xulashada
Fiber cudbi ah oo saafi ah oo ah walxo ceeriin ah oo hoos yimaada xaaladaha alkaline ee gaarka ah
etherification iyo diyaarinta.Waxay leedahay sifooyinka awoodda dhumucdiisuna, caabbinta milixda, content dambaska hoose, xasilloonida PH, haynta biyaha
xasilloonida cabbirka, samaynta filim samaynta fiican, iyo caariyaysi badan oo caariyaysi ah,
kala firdhinta iyo ku dhegganaanshaha.
Warshadaha dhismaha
1.Dhismaha sibidhka
2.Ceramic tile cement
3.Asbestos iyo daahan kale oo refractory: sida wakiilka ganaax, hagaajinta dheecaanka, laakiin sidoo kale hagaajinaysaa adhesion ee substrate ah.
4.Gypsum coagulant slurry: wanaaji xajinta biyaha iyo shaqaynta, wanaaji xabagta substrate-ka
5. Sibidhka wadajirka ah: lagu daray sibidhka wadajirka ah ee dhulka loogu talagalay guddiga gypsum si loo hagaajiyo dareeraha iyo xajinta biyaha
