Kodi mungasankhe bwanji hydroxypypyl methylcellulose ya matope?

Mtengo wa pH ya gypsum zinthu ndi acidic kapena osalowerera. Tsopano pali mitundu iwiri ya zomangamangahydroxypypyl methylcellulosePa msika: Kusungunuka pang'onopang'ono cellulose ndi cellulose (ma cell). Cellose nthawi yomweyo sioyenera ma gypsumu. Zogulitsa, kusungunuka sikumakhala wosauka kwambiri pansi pa acidic kapena kusalowerera ndale, komanso kusungunuka pang'onopang'ono kwa methylcellulose kumatha kusungunuka kwa gyploose, ndikosavuta kwa matope (pomwe gypsum pambuyo pa matope? khoma kwakanthawi kochepa, mawanga ang'onoang'ono amawoneka pansi). Pakadali pano, muzogulitsa gypsum, makamaka m'matope a gypyumu, amafunikira kuti ma ethel ether amatha kubalalitsa nthawi yochepa kwambiri, yomwe imafunikira kufufuza mozama pa cellulose pang'onopang'ono Njira. Pamtunda (osati omwe amatchedwa kuwonjezera zina zowonjezera mu cell ether ether), kuti azolowere matope a gypsum. Hydroxypylropyl a methasel ether ndi chithandizo chozama amatha kukhala ndi nthawi yopuma komanso mphamvu yamatope ku gypsum matope, ndipo amatha kusintha matope.
