Hydroxypropyl methylcellulose ether (HPMC) ine kuchengetedza kwemvura uye kukora mhedzisiro mune simende dhaka uye gypsum-based mortar, uye inogona kuvandudza zvine musoro kunamatira uye kuchinjika kuramba kwedhaka.
Zvinhu zvakadai sekushisa kwegasi, tembiricha, uye gasi kudzvanywa kwegasi zvinokanganisa mwero wekubuda kwemvura mumatope esimende uye zvigadzirwa zvegypsum.Naizvozvo, huwandu hwakafanana hwekutengesa hydroxypropyl methylcellulose ether (HPMC) yakawedzerwa kuchengetedza kuwanikwa kwemvura inosiyana kubva mumwaka nemwaka.
Paunenge uchidurura kongiri, mhedzisiro yekuvhara kwemvura inogona kugadziriswa maererano nekuwedzera kana kuderera kwekuyerera kwakanyanya.Mwero wekuvhara mvura wehydroxypropyl methylcellulose ether pakupisa kwepamusoro ndiyo yakakosha chiratidzo kukosha kusiyanisa kunaka kwehydroxypropyl methylcellulose ether.
Yepamusoro-mhando hydroxypropyl methylcellulose ether (HPMC) zvigadzirwa zvinogona kugadzirisa zvine musoro dambudziko rekushisa kwemvura kukiya kukiya.Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzine hunyoro uye zvivakwa zveinjiniya zvechromatography, zvinodikanwa kushandisa yepamusoro hydroxypropyl methylcellulose ether (HPMC) kuvandudza kunyungudika kwemvura kweslurry.
Chikamu chepamusoro-soro hydroxypropyl methylcellulose ether (HPMC) yakanyatsofanana, uye mapoka ayo methoxy uye hydroxypropyl akagoverwa zvakaenzana pane molecular chimiro cheni yemethyl cellulose, iyo inogona kuwedzera chizvarwa cheokisijeni mamorekuru pane hydroxyl uye ether zvisungo.Iko kukwanisa kwe covalent zvisungo kushanda.
Inogona kudzora zvine musoro kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana mhedzisiro chaiyo yekuvhara kwemvura yakakwira.Yepamusoro-mhando yeHydroxypropyl Methylcellulose Ether (HPMC) inowanikwa mumadhaka akasanganiswa uye plaster yehunyanzvi hweParis.
Zvose zvimedu zvakasimba zvakaputirwa kuita firimu rakanyorova.Mvura yakajairika inoburitswa zvishoma nezvishoma kwenguva yakareba uye inosangana nekuita coagulation ine inorganic zvinhu uye collagen zvinhu kuti ive nechokwadi chekubatana kwesimba rekumanikidza uye kusimba kwesimba.
Naizvozvo, munzvimbo dzepamusoro-tembiricha yekuvaka nzvimbo muzhizha, kuitira kuti vawane mhedzisiro chaiyo yekuchengetedza mvura, vanhu vanofanirwa kuwedzera emhando yepamusoro hydroxypropyl methylcellulose ether (HPMC) zvigadzirwa zvinoenderana nechakavanzika resipi, zvikasadaro vanozoshaya mvura nekuda kushomeka kwemvura.Zvigadzirwa zvemhando dzakadai sekusimba, kuderedzwa kwesimba rekumanikidza, kutsemuka, mabulges emhepo, nezvimwe zvinokonzera kuomesa zvakanyanya.
Izvi zvinowedzerawo kuoma kwekuvaka kwevashandi.Sezvo tembiricha inodzikira, iyo yakawedzerwa huwandu hwehydroxypropyl methylcellulose ether (HPMC) inodzikira zvishoma nezvishoma kuti iwane humwe hunyoro hwemukati.
