HPMC (CAS:9004-65-3), sekuwedzera kunoshandiswa zvakanyanya mumunda wezvigadzirwa zvekuvaka, inonyanya kushandiswa kuchengetedza mvura, kukora uye kuvandudza kushanda kwechigadzirwa chakapedzwa.Kuchengetwa kwemvura ndechimwe chezviratidzo zvakakosha kana iwe. sarudza yemhando yepamusoro HPMC, saka ngatitarisei zvakanyanya pazvinhu zvinokanganisa mwero wekuchengetedza mvura weHPMC.
1.Chiyero cheHPMC, uye kushanda kwayo kwekuchengetedza mvura kwakanyatsoenderana nehuwandu hwakawedzerwa. Huwandu hweHPMC hunoshandiswa mukuvaka zvinhu pamusika hunosiyana zvichienderana nemhando. Iyo inowanzowedzerwa mune senge bonding, plastering, anti-cracking dhaka, nezvimwe. Iyo yakawanda yekuwedzera huwandu ndeye 2 ~ 2.5 KG / MT, iyo inowedzera huwandu hweputty etc. iri pakati pe2 ~ 4.5 KG/MT, iyo tile glue iri. pakati pe 3.5 ~ 4 KG / MT, uye huwandu hwe tile grout ndeye 0.3 ~ 1 KG / MT maererano nenzira dzakasiyana dzekuvaka, gap upamhi uye slurry fineness, dhaka rekuzvimiririra riri pakati pe0.2 ~ 0.6 KG / MT, uye ETICS. iri pakati pe4 ~ 7 KG/MT. Mukati memhando iyi, iyo yakawanda HPMC inowedzerwa, mashandiro ekuchengetedza mvura angave nani.
2.Kukanganisa kwenzvimbo yekuvaka. Humidity yemhepo, tembiricha, kudzvinyirirwa kwemhepo, kumhanya kwemhepo uye zvimwe zvinhu zvinokanganisa mwero wekuvhuvhuta kwemvura mumatope esimende uye zvigadzirwa zvegypsum. Mumwaka wakasiyana uye matunhu akasiyana, mwero wekuchengetedza mvura wechigadzirwa chimwe chete uchasiyana, asi kazhinji, Tembiricha ine simba guru pachiyero chekuchengetedza mvura, saka pane maonero pamusika: HPMC ine tembiricha yegel yakakwirira. -mhando yechigadzirwa nepamusoro pekuchengetedza mvura.
3.Iyo nzira yekugadzira uye viscosity ye cellulose ether -HPMC. Iwo methoxy uye hydroxypropoxy mapoka akagoverwa zvakaenzana pamwe chete ne cellulose molecular chain, iyo inogona kuwedzera kubatanidzwa kwemaatomu eokisijeni pane hydroxyl uye ether zvisungo nemvura. Kugona kwehydrogen bonding kunoita kuti mvura yemahara ive yakasungwa mvura, nekudaro ichinyatso kudzora kubuda kwemvura uye kuwana yakanyanya kuchengetwa kwemvura.
Kana iyo viscosity yeHPMC ichiwedzera, mwero wekuchengetedza mvura unowedzerawo, iyo viscosity inosvika pane imwe nhanho, chiyero chekuchengetedza mvura chinowedzera. Inoita kunge yakati sandarara. Maonero ari nyore. Basa rekuchengetedza mvura reHPMC rinokanganiswa nemativi ese. Sarudzo haigone kuve yakavakirwa pane imwe chiratidzo.
