Hydroxypypyl methyl cellulose mu simenti ndi gypsum yochokera pulasitala

HPMC hydroxypypyl cellulose mu matope a simenti ndi gypsum slurry, makamaka amasewera gawo lamadzi ndikukula, zimatha kusintha mogwirizana ndi kusakanikirana kwa slurry.

Kutentha kwa mpweya, kutentha ndi kuchuluka kwa chiwopsezo kumatha kukhudza madzi amtunduwu mu matope a simenti ndi gypsum. Chifukwa chake mu nyengo zosiyanasiyana, kuwonjezera hydroxypropyl methy cellulose kuchuluka kwa madzi omwe ali ndi madzi omwe ali ndi kusiyana. Mu konkriti yomanga, madzi osungirako madzi a slurry amatha kusinthidwa ndikukulitsa kuchuluka kwa HPMC. Kusunga kwamadzi kwa methyl cellulose ether kutentha kwambiri ndi chizindikiro chofunikira kusiyanitsa mtundu wa methyl cellulose ether.

Zabwino kwambiri hydroxpyl methyl cellulose zotsatizana zimatha kuthana ndi vuto la madzi osungidwa kutentha kwambiri. Mu nyengo yotentha, makamaka m'malo otentha ndi owuma ndi zomangira zowonda mbali yadzuwa, kufunika kwa HPMC yayikulu kuti isungidwe madzi osungira. hydroxypropyl me cellulose (hpmc), kufanana kwambiri ndikwabwino, ndi mpweya wa ma hydroxyl Chinyontho chotuluka, chikwaniritsani madzi ambiri.

Mulingo wapamwamba wa hydroxypropyl methy cellulose amatha kufalitsa mosafanana komanso bwino matope a simenti, ndikupanga mphamvu yonyowa, ndikuwonetsetsa kuti mphamvu ya zinthuzi ndi yovuta.

Pomanga, kuti akwaniritse mphamvu zakusunga madzi, muyenera kuwonjezera zinthu zapamwamba za HPMC malinga ndi njira, kupatulapo, padzagwada kwambiri, kuwonongeka kwa makoswe, komanso kuwonjezera zovuta za ogwira ntchito. Kutentha kwa kutentha kumachepa, kuchuluka kwa HPMC imatha kuchepetsedwa pang'onopang'ono, ndipo madzi omwewo atha kukwaniritsidwa.
