Cellulose ether hpmc ine basa rekuchengetedza mvura uye kukora mumota yesimende uye gypsum-based mortar, izvo zvinogona kuvandudza kunamira uye kuramba kwakamira kwezvinhu zvemota.
Zvinhu zvakaita sekupisa kwegasi, tembiricha uye mwero wekumanikidzwa kwemhepo zvine mhedzisiro yakaipa pahuwandu hwekubuda kwemvura kubva mumota yesimende uye zvigadzirwa zvakagadzirwa negypsum. Nokudaro, pane misiyano mukuwedzera huwandu hwakafanana hwezvigadzirwa zveHPMC kuchengetedza kushanda zvakanaka kwemvura mumwaka wega wega.
Mukudurura kongiri, kuvharika kwemvura kunogona kugadziriswa nekuwedzera nekuderedza kuyerera kwechikamu. Kuchengetwa kwemvura kwemethyl cellulose ether pakupisa kwakanyanya ndicho chinhu chikuru chinoratidza kunaka kwemethyl cellulose ether.
Zvigadzirwa zveHPMC zvemhando yepamusoro zvinogona kugadzirisa dambudziko rekuvharika kwemvura panguva yekupisa kwakanyanya. Munguva dzekupisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzine hunyoro uye kugadzirwa kwechromatography, HPMC yemhando yepamusoro inodiwa kuti mvura irambe ichichengetwa zvakanaka.
HPMC yemhando yepamusoro yakarongwa zvakanaka, uye mapoka ayo emethoxyl nehydroxypropyl akagoverwa zvakaenzana pacheni yemamorekuru e cellulose, izvo zvinogona kuwedzera kugona kwemamorekuru eokisijeni kuumba ma covalent bonds pa hydroxyl ne ether bonds.
Inogona kudzora kupwanyika kwemvura kunokonzerwa nemamiriro ekunze anopisa uye inoita kuti mvura ivhare zvakanyanya. HPMC yemhando yepamusoro inogona kushandiswa mudhaka rakasanganiswa uye plaster yakagadzirwa nemaoko eparis.
Dururirai zvidimbu zvese zvakasimba kuti mugadzire firimu rakanyorova, uye hunyoro huri muhurongwa hwezuva nezuva huchaburitswa zvishoma nezvishoma kwenguva yakareba, uye huchasangana nezvinhu zvisina organic nezvinhu zve collagen kuti muve nechokwadi chekuti kubatana kwacho kwakasimba uye simba rekusunga.
Saka, munzvimbo yekuvaka yezhizha rinopisa, kuti tikwanise kuchengetedza mvura, tinofanira kuwedzera zvigadzirwa zveHPMC zvemhando yepamusoro zvichienderana neresipi, zvikasadaro, zvichakonzerwa nekushaikwa kwekuoma, kusimba kushoma, kutsemuka, madhiramu egasi nezvimwe zvinetso zvemhando yezvigadzirwa. Zvinokonzera kuoma nekukurumidza.
Izvi zvinowedzerawo kuoma kwekuvaka kwevashandi. Sezvo tembiricha ichidzikira, huwandu hweHPMC hunowedzerwa hunodzikira zvishoma nezvishoma kuti huwane hunyoro hwakafanana.
