Mune simende dhaka uye gypsum-based slurry, HPMC inonyanya kutamba basa rekuchengetedza mvura uye kukora.Inogona kunyatso kuvandudza simba rinosunga uye anti-pituitarism ye slurry.
Tembiricha yemhepo, tembiricha yemhepo uye mhepo yekumhanya kwemhepo inokanganisa chiyero chekuvhuvhuta chemvura mumatope esimende uye zvigadzirwa zvegypsum.
Mumwaka wakasiyana, kune mimwe misiyano mukuchengetedza mvura kweHPMC.Mukuvaka chaiko, iyo yekuchengeta mvura mhedzisiro yeslurry inogona kugadziriswa nekuwedzera kana kudzikisa huwandu hweHPMC hwakawedzerwa.Kuchengetwa kwemvura kwemethyl cellulose ether pasi pemamiriro ekushisa kwakanyanya chiratidzo chakakosha chekusiyanisa kunaka kwemethyl cellulose ether.Yakanakisa HPMC yakatevedzana zvigadzirwa zvinogona kunyatsogadzirisa dambudziko rekuchengetedza mvura pasi pekushisa kwakanyanya.
Mumwaka wekushisa wepamusoro, kunyanya munzvimbo dzinopisa uye dzakaoma uye dzakatetepa-layer kuvaka padivi rezuva.Yemhando yepamusoro HPMC inodiwa kuvandudza kuchengetwa kwemvura kweiyo slurry.Inogona kuvandudza kugona kweatomu reokisijeni paboka rehydroxyl kuumba hydrogen bond ine ether bond.Ita mvura yemahara mumvura yakasungwa, kuitira kuti unyatso kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze.Mvura yakakwirira yekuchengetedza.
Yepamusoro-mhando cellulose HPMC inogona kuparadzirwa zvakafanana uye zvinobudirira mumatope esimende uye gypsum-based zvigadzirwa.Uye putira zvese zvakasimba zvimedu kuti uite firimu rekunyorova.Hunyoro huri mu base layer hunoburitswa zvishoma nezvishoma kwenguva yakareba, uye inorganic gelling material inosangana ne hydration reaction.Nekudaro kuve nechokwadi chekusimba kwechisungo uye kusimba kwekumanikidza kwezvinhu.Naizvozvo, inofanirwa kuvakwa mukupisa kwezhizha zhizha kuti iwane kuchengetedza kwemvura.Iva nechokwadi chekuwedzera emhando yepamusoro HPMC zvigadzirwa zvinoenderana neformula, zvikasadaro pachave nemhando yezvinetso senge kusakwana hydration.Asi zvinowedzerawo kuoma kwekuvaka kwevashandi.Sezvo tembiricha inodonha, huwandu hweHPMC hunogona kudzikiswa zvishoma nezvishoma, uye iyo yekuchengetedza mvura inogona kuwanikwa zvakare.
