HPMC Hydroxypropyl methyl cellulose mune simende dhaka uye gypsum slurry, inonyanya kutamba basa rekuchengetedza mvura uye kukora, inogona kunyatso kuvandudza kunamatira uye sag kuramba kweslurry.
Tembiricha yemhepo, tembiricha uye mwero wekumanikidza kwemhepo zvinogona kukanganisa chiyero chekubuda kwemvura mumatope esimende uye zvigadzirwa zvegypsum.Saka mumwaka wakasiyana, kuwedzera hydroxypropyl methyl cellulose yakaenzana huwandu hwechigadzirwa chekuchengetedza mvura ine mimwe misiyano.Mukuvaka kongiri, iyo yekuchengeta mvura mhedzisiro yeslurry inogona kugadziriswa nekuwedzera kana kudzikisa huwandu hweHPMC.Kuchengetwa kwemvura kwemethyl cellulose ether pakupisa kwepamusoro chiratidzo chakakosha chekusiyanisa kunaka kwemethyl cellulose ether.
Yakanakisa hydroxypropyl methyl cellulose yakatevedzana zvigadzirwa zvinogona kunyatsogadzirisa dambudziko rekuchengetedza mvura pasi pekupisa kwakanyanya.Mumwaka wekushisa wepamusoro, kunyanya munzvimbo dzinopisa uye dzakaoma uye kuvakwa kwakatetepa padivi pezuva, kudiwa kwepamusoro-soro HPMC yekuvandudza kuchengetwa kwemvura kweslurry;hydroxypropyl methyl cellulose (HPMC), kufanana kwakanaka kwazvo, iokisijeni uye okisijeni hydroxypropyl mapoka akagoverwa zvakaenzana pamwe chete neketani ye cellulose, inogona kuvandudza iyo hydroxyl uye ether okisijeni uye mvura pane kiyi yekubatanidza fomu hydrogen bonding kugona, kuita yemahara mvura ye hydration, kuitira kuti unyatso kudzora mamiriro ekunze ekupisa anokonzerwa nekunyorova kwemvura, Wana kuchengetwa kwemvura yakawanda.
Hunhu hwepamusoro hwehydroxypropyl methyl cellulose inogona kupararira zvakafanana uye zvinobudirira mudhaka resimende uye plaster zvigadzirwa, uye kurongedza zvese zvimedu zvimedu, uye kugadzira dhizaini rekunyorova firimu, hunyoro huri mujinga kwenguva yakareba zvishoma nezvishoma hunoburitswa, uye inorganic cementitious material hydration reaction. , kuitira kuti ive nechokwadi chekusimba kwechisungo uye kusimba kwekumanikidza kwezvinhu.
Mukuvaka, kuitira kuti uwane mhedzisiro yekuchengetedza mvura, inofanirwa kuwedzera mhando yepamusoro yeHPMC zvigadzirwa zvinoenderana neformula, zvikasadaro, pachave nekuoma nekukurumidza kunokonzerwa nekusakwana hydration, kuderedzwa kwesimba, kuputika, hollow dhiramu uye kubuda kwemhando. matambudziko, asiwo kuwedzera kuoma kwevashandi kuvaka.Sezvo tembiricha inoderera, huwandu hwemvura HPMC hunogona kuderedzwa zvishoma nezvishoma, uye iyo yakafanana yekuchengetedza mvura inogona kuwanikwa.
