Cellulose ether hpmc ine basa rekuchengetedza mvura uye kukora mudhaka resimende uye gypsum-based mortar, iyo inogona kunyatso kuvandudza kunamatira uye kusimba kupikisa kwezvinhu zvedhaka.
Zvinhu zvakadai setembiricha yegesi, tembiricha uye mwero wekumanikidza kwemhepo zvine kukanganisa pachiyero chekubuda kwehunyoro kubva kudhaka resimende uye zvigadzirwa zvegypsum. Naizvozvo, pane misiyano yekuwedzera huwandu hwakafanana hwezvigadzirwa zveHPMC kuchengetedza mvura inoshanda mumwaka wega wega.
Mukudururwa kwekongiri, mvura yekuvhara mhedzisiro inogona kugadziridzwa nekuwedzera uye nekuderedza kuyerera kwechikamu. Mwero wekuchengetedza mvura wemethyl cellulose ether pakupisa kwepamusoro ndiyo yakakosha index kukosha kusiyanisa kunaka kwemethyl cellulose ether.
Zvigadzirwa zvemhando yepamusoro zveHPMC zvinogona kugadzirisa dambudziko rekuvhara kwemvura yepamusoro. Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzine hunyoro uye kuvaka chromatography, HPMC yemhando yepamusoro inodiwa kuvandudza kuchengetwa kwemvura kweslurry.
Yepamusoro-mhando HPMC yakanyatso kurongeka, uye mapoka ayo methoxyl uye hydroxypropyl akagoverwa zvakaenzana pane molecular cheni ye cellulose, iyo inogona kuwedzera kugona kwemaokisijeni mamorekuru kuumba covalent zvisungo pahydroxyl uye ether bond.
Inogona kunyatso kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana yakakwirira yekuvhara mvura. Yepamusoro-mhando methylcellulose HPMC inogona kushandiswa mune yakasanganiswa dhaka uye plaster yeParis mhizha.
Encapsulate zvese zvakasimba zvimedu kuti zvigadzire firimu rakanyorova, uye hunyoro huri muhurongwa huchaburitswa zvishoma nezvishoma kwenguva yakareba, uye kuita neinorganic zvinhu uye collagen zvinhu kuti ive nechokwadi chekubatanidza kusimba uye kusimba kwekusimba.
Naizvozvo, munzvimbo inopisa yekuvaka yezhizha, kuitira kuti tiwane mhedzisiro yekuchengetedza mvura, isu tinofanirwa kuwedzera emhando yepamusoro zvigadzirwa zveHPMC zvinoenderana neresipi, zvikasadaro, zvichakonzerwa nekushaikwa kwekusimba, kuderedzwa kwesimba, kuputika, gasi dhiramu. uye mamwe matambudziko emhando yechigadzirwa. Zvinokonzera kuoma nekukurumidza.
Izvi zvinowedzerawo kuoma kwekuvaka kwevashandi. Sezvo tembiricha inodzikira, huwandu hweHPMC hunowedzerwa zvishoma nezvishoma kuti huwane hunyoro hwakafanana.
