Hydroxypropyl methylcellulose (HPMC) is cellulose ether inowanzoshandiswa mumaindasitiri akasiyana, kusanganisira gypsum muindasitiri yekuvaka. Iyi komputa ine basa rakawanda inoita basa rakakosha mukuvandudza mashandiro uye zvimiro zvegypsum plaster.
1. Nhanganyaya kuHPMC:
Hydroxypropyl methylcellulose inogadzirwa kubva kune yakasikwa polymer cellulose. Inogadzirwa nekurapa cellulose nepropylene oxide uye methyl chloride. Mhedzisiro iyi polymer inonyungudika nemvura ine yakasarudzika zvivakwa inogona kuwana maapplication muakasiyana maindasitiri.
2. Kuita kweHPMC:
Kunyungudika kwemvura: HPMC inonyungudika nyore nyore mumvura, ichigadzira yakajeka uye isina ruvara mhinduro.
Mafirimu ekugadzira zvinhu: Mafirimu-ekugadzira zvinhu anobatsira kugadzira firimu rinodzivirira pamusoro.
Thermal gelation: HPMC inosangana ne reversible thermal gelation, zvinoreva kuti inogona kugadzira gel pakupisa kwakanyanya uye kudzokera kune mhinduro pakutonhora.
Viscosity: Iyo viscosity yeHPMC mhinduro inogona kugadziridzwa zvichienderana nehuwandu hwekutsiva uye huremu hwemamorekuru.
3. Kushandiswa kweHPMC mugypsum:
Kuchengetedzwa kwemvura: HPMC inoshanda semugadziri wekuchengetedza mvura mugypsum, kudzivirira kurasikirwa nekukurumidza kwemvura panguva yekumisa. Izvi zvinowedzera maneuverability uye zvinopa hupenyu hurefu hwekushandisa.
Yakavandudzwa Kunamatira: Iyo firimu-inogadzira zvimiro zveHPMC inobatsira kuvandudza stucco kunamatira kune akasiyana ma substrates, kugadzira chisungo chakasimba.
Consistency Control: Nekudzora viscosity yemusanganiswa wegypsum, HPMC inobatsira kuchengetedza kuenderana kwekushandisa, kuve nechokwadi chekuti yunifomu yepamusoro kupera.
Crack Resistance: Kushandisa HPMC mune plaster kunobatsira kuvandudza kushanduka uye kunoderedza mukana wekutsemuka muchigadzirwa chakapedzwa.
Kuisa Nguva: HPMC inogona kukanganisa nguva yekuseta yegypsum saka inogona kugadziridzwa kuti isangane nezvinodiwa zvekushandisa.
4. Dosage uye kusanganisa:
Huwandu hweHPMC hunoshandiswa mugypsum hunoenderana nezvakasiyana siyana senge zvivakwa zvinodiwa, gypsum kuumbwa uye zvinodiwa zvekushandisa. Kazhinji, inowedzerwa kune yakaoma musanganiswa panguva yekusanganiswa. Kusanganisa maitiro kwakakosha kuti uve nechokwadi chekupararira kwakafanana uye kuita kwakakwana.
5.Kuenderana uye chengetedzo:
HPMC inowirirana nezvimwe zvakasiyana-siyana zvekuwedzera zvinoshandiswa mukugadzira plaster. Pamusoro pezvo, inoonekwa seyakachengeteka kuti ishandiswe mune zvekuvaka uye inoenderana neakakodzera mitemo.
6. Mhedziso:
Hydroxypropyl methylcellulose (HPMC) inoita basa rakakosha mukuvandudza mashandiro egypsum plaster. Hunhu hwayo hwakasiyana hunobatsira kuvandudza kushanda, kunamatira uye huwandu hwese hwepurasita. Chiwedzerwa chinoshandiswa zvakanyanya muindasitiri yekuvaka, HPMC inoramba iri chinhu chakakosha chemhando yepamusoro plaster maumbirwo.
