Makampani opanga zomangamanga padziko lonse lapansi akusintha mwachangu, chifukwa cha kufunikira kwakukulu kwazipangizo zogwirira ntchito bwino kwambiri, njira zomangira mwachangu, kukhazikika bwino, komanso kugwira ntchito bwinoPakati pa zipangizo zamakono zomangira,matope opangidwa ndi gypsumZakhala zofunika kwambiri chifukwa cha kupepuka kwawo, kukana moto, kusalala, komanso kugwiritsa ntchito mosavuta.
Pamene msika wa ma gypsum plaster, ma joint compounds, ma self-leveling systems, ndi ma mortars okongoletsera ukukulirakulira, opanga akuyang'ana kwambiri pakukonza ma formula pogwiritsa ntchito zowonjezera zapamwamba. Pakati pa zowonjezerazi,starch etheryakhala yofunika kwambiri chifukwa cha mphamvu zake zapadera zosamalira mafupa ndi madzi.
Akaphatikizidwa ndi ma ether a cellulose monga HPMCndiMHEC, starch ether imapanga zodabwitsazotsatira zogwirizana, zomwe zimathandizira kwambiri magwiridwe antchito a mortars okhala ndi gypsum.
Nkhaniyi ikufotokoza za kapangidwe kake, njira, ntchito, ndi tsogolo la starch ether mu makina a matope okhala ndi gypsum.
1. Kumvetsetsa Ma Mortar Ochokera ku Gypsum
Ma mortars okhala ndi gypsum ndi zipangizo zomangira zouma zomwe zimapangidwa makamaka ndi:
- Calcium sulfate hemihydrate
