HPMC inonyanya kuita basa rekuchengetedza mvura uye kukora mumatope esimende uye gypsum-based slurry, iyo inogona kunyatso kuvandudza kubatana uye sag kuramba kweslurry.
Zvinhu zvakadai sekushisa kwemhepo, tembiricha uye kudzvanywa kwemhepo zvinokanganisa chiyero chekubuda kwemvura mudhaka resimende uye zvigadzirwa zvegypsum.Naizvozvo, mumwaka wakasiyana, uchiwedzera huwandu hwakafanana hweHPMC, iyo mvura yekuchengetedza mhedzisiro yezvigadzirwa zvine mimwe misiyano.Kuchengetwa kwemvura kwemethyl cellulose ether pakupisa kwepamusoro chiratidzo chakakosha chekusiyanisa kunaka kwemethyl cellulose ether.Yakanakisa HPMC inogona kugadzirisa zvinobudirira dambudziko rekuchengetedza mvura pasi pekushisa kwakanyanya.Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzakaoma uye dzakatetepa-layer kuvakwa padivi rezuva, yemhando yepamusoro HPMC inodiwa kuvandudza kuchengetwa kwemvura kweslurry.Yepamusoro-mhando HPMC, ine kufanana kwakanaka kwazvo, mapoka ayo emethoxy uye hydroxypropoxy akagoverwa zvakaenzana pamwe chete ne cellulose molecular chain, iyo inogona kuvandudza kugona kwemaatomu eokisijeni pa hydroxyl uye ether zvisungo kuti zvibatane nemvura kuita hydrogen bond, kuti mvura yakasununguka inova yakasungwa mvura, kuitira kuti inyatso kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana mvura yakakwirira yekuchengetedza.
High-quality cellulose HPMC inogona kuparadzirwa zvakafanana uye inobudirira mudhaka resimende uye gypsum-based products, uye inovhara zvikamu zvose zvakasimba, uye inoumba firimu rekunyorova, uye hunyoro huri mujinga hunobudiswa zvishoma nezvishoma kwenguva yakareba.Iyo hydration reaction yeiyo coagulating zvinhu inoitika, nekudaro kuve nechokwadi chekubatana kwesimba uye kumanikidza kusimba kwechinhu.Naizvozvo, mukupisa kwekushisa kwezhizha kuvaka, kuti uwane mhedzisiro yekuchengetedza mvura, zvinodikanwa kuti uwedzere emhando yepamusoro zvigadzirwa zveHPMC zvinoenderana neformula, zvikasadaro, pachave nekusakwana hydration, kudzikisa simba, kuputika, kuputika uye kudonha. zvinokonzerwa nekunyanya kuomesa.Kunowedzerawo kuoma kwekuvaka kwevashandi.Sezvo tembiricha inodzikira, huwandu hwekuwedzera hweHPMC hunogona kudzikiswa zvishoma nezvishoma, uye iyo yakafanana yekuchengetedza mvura inogona kuwanikwa.
