Hydroxypropyl methyl cellulose ether (HPMC) ine basa rekuchengetedza mvura uye kukora mudhaka resimende uye gypsum-based dhaka, uye inogona kunyatso kuvandudza kunamatira uye kuchinjika kuramba kwezvinhu zvedhaka.
Zvinhu zvakadai setembiricha yegesi, tembiricha uye mwero wekumanikidza kwemhepo zvine kukanganisa pachiyero chekubuda kwehunyoro kubva kudhaka resimende uye zvigadzirwa zvegypsum. Naizvozvo, mumwaka wega wega, pane mimwe misiyano yekuwedzera huwandu hwakafanana hwehydroxypropyl methylcellulose ether (HPMC) zvigadzirwa kuchengetedza kushanda kwemvura.
Mukudururwa kwekongiri, mvura yekuvhara mhedzisiro inogona kugadziridzwa nekuwedzera uye nekuderedza kuyerera kwechikamu. Mwero wekuchengetedza mvura wehydroxypropyl methyl cellulose ether pakupisa kwepamusoro ndiyo yakakosha index kukosha kusiyanisa kunaka kwehydroxypropyl methyl cellulose ether.
High-quality hydroxypropyl methylcellulose (HPMC) zvigadzirwa zvinogona kunyatsogadzirisa dambudziko rekupisa kwemvura yekuchengetedza mvura. Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzine hunyoro uye kuvaka chromatography, yakakwirira-mhando hydroxypropyl methylcellulose ether (HPMC) inodiwa kuvandudza kuchengetwa kwemvura kweslurry.
Yepamusoro-mhando hydroxypropyl methylcellulose ether (HPMC) yakanyatso kurongeka, uye methoxyl uye hydroxypropyl mapoka ayo akagoverwa zvakaenzana pane molecular chimiro cheni yemethylcellulose, iyo inogona kukurudzira kugadzirwa kweokisijeni mamorekuru pahydroxyl uye ether bond. Kugona kushanda nema covalent bonds.
Inogona kunyatso kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana yakakwirira yekuvhara mvura. Yepamusoro-mhando hydroxypropyl methylcellulose (HPMC) inogona kushandiswa mune yakasanganiswa dhaka uye plaster mhizha.
Encapsulate zvese zvakasimba zvimedu kuti zvigadzire firimu rakanyorova, uye hunyoro huri muhurongwa huchaburitswa zvishoma nezvishoma kwenguva yakareba, uye ita ne organic matter uye collagen kuti ive nechokwadi chekubatanidza kusimba uye kusimba kwesimba.
Nokudaro, kuitira kuchengetedza mvura panzvimbo yekuvaka muzhizha rinopisa, tinofanira kuwedzera zvigadzirwa zvepamusoro-soro hydroxypropyl methylcellulose (HPMC) maererano neresiphi, kana zvisina kudaro, zvichave nekuda kwekushaya coagulation, kuderedzwa simba, Kupwanya, gasi dhiramu. uye mamwe matambudziko emhando yechigadzirwa anokonzerwa nekunyanya kuomesa.
Izvi zvinowedzerawo kuoma kwekuvaka kwevashandi. Sezvo tembiricha inodzikira, huwandu hwehydroxypropyl methylcellulose ether (HPMC) hunodzikira zvishoma nezvishoma kuti huwane hunyoro hwakafanana.
