Kuchengetedzwa kwemvura kubvaHydroxypropyl Methyl Cellulosechimwe chezvinhu zvakakosha zveHydroxypropyl Methyl Cellulose. Zvinhu zvakadai semhepo tembiricha, tembiricha uye kumhanya kwemhepo zvinokanganisa huwandu hwekuvhuvhuta kwemvura mumatope esimende uye zvigadzirwa zvegypsum. Naizvozvo, mumwaka wakasiyana, kune mimwe misiyano mukuchengetedza kwemvura mhedzisiro yezvigadzirwa zvine huwandu hwakafanana hweHydroxypropyl Methyl Cellulose yakawedzerwa.
Kazhinji, iyo yakakwirira viscosity yeHydroxypropyl Methyl Cellulose, zviri nani kuchengetedza mvura kuchaita, asi mhedzisiro yeviscosity pakuchengetedza mvura ichaderedzwa kana viscosity ichipfuura 100,000 mpa.s. Kune Hydroxypropyl Methyl Cellulose ine viscosity inopfuura 100,000, zvinodikanwa kuwedzera huwandu hweHydroxypropyl Methyl Cellulose kuti iwedzere zvakanyanya mwero wekuchengetedza mvura.
Muchivakwa chakananga, iyo mvura yekuchengetedza mhedzisiro yeslurry inogona kugadziriswa nekuwedzera kana kudzikisa huwandu hweHydroxypropyl Methyl Cellulose. Hydroxypropyl Methyl Cellulose akatevedzana zvigadzirwa zvinogona kunyatsogadzirisa dambudziko rekuchengetedza mvura pasi pekupisa kwakanyanya. Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzakaoma uye dzakatetepa-layer kuvaka padivi rezuva, yepamusoro-mhando hydroxypropyl methylcellulose inodiwa kuvandudza kuchengetwa kwemvura kweslurry.
Yepamusoro-mhando Hydroxypropyl Methyl Cellulose ine yakanaka kwazvo yakafanana. Iwo maMethoxy uye Hydroxypropoxy mapoka akagoverwa zvakaenzana pamwe chete ne cellulose molecular chain. Inogona kuvandudza maatomu eokisijeni pahydroxyl uye ether bond. Kugona kwekubatana kwemvura kuumba hydrogen zvisungo zvinoshandura mvura yemahara kuita mvura yakasungwa, nekudaro kudzora zvinobudirira kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana yakakwirira yekuchengetedza mvura.
Yepamusoro-sorohydroxypropyl methyl celluloseinogona kupararira zvakaenzana uye zvinobudirira mudhaka resimende uye gypsum-based products, kuputira zvese zvakasimba zvimedu, uye kuumba firimu rakanyorova, uye hunyoro huri muchigadziko huchasunungurwa zvishoma nezvishoma kwenguva yakareba. A hydration reaction inoitika neiyo inorganic gelling zvinhu, nekudaro kuve nechokwadi chekusimba kwechisungo uye kumanikidza kusimba kwechinhu. Nokudaro, mukugadzirwa kwezhizha kwepamusoro-soro, kuitira kuti uwane simba rekuchengetedza mvura, zvakakosha kuwedzera zvigadzirwa zveHydroxypropyl Methyl Cellulose muhuwandu hwakakwana maererano nefomula, kana zvisina kudaro, kusakwana kwemvura, kuderera kwesimba, uye kuputika kuchaitika nekuda kwekunyanya kuoma. Zvinetso zvemhando yakadai sekuchera, kuchera nekudonha zvinowedzerawo kuoma kwekuvaka kwevashandi. Sezvo tembiricha inodonha, huwandu hweHydroxypropyl Methyl Cellulose hwakawedzerwa hunogona kudzikiswa zvishoma nezvishoma, uye iyo yakafanana yekuchengetedza mvura inogona kuwanikwa.
