Ehe, Hydroxyethyl Methyl Cellulose (HEMC) inowanzo shandiswa sekuwedzera kwekuita mune gypsum plaster maumbirwo.Gypsum plaster, inozivikanwawo sepurasita yeParis, chivakwa chinoshandiswa zvakanyanya chemukati memadziro ekupedzisa uye yekushongedza maapplication.HEMC inoshanda akati wandei akakosha mabasa mu gypsum plaster formulations:

1. Kuchengetwa Kwemvura: HEMC inobatsira kuchengetedza mvura mumusanganiswa wegypsum plaster, kuve nechokwadi chekuti hydration yakakodzera yegypsum particles uye kurebesa kushanda kwepurasita.Izvi zvinoita kuti zvive nyore kushandisa uye kupera kwakapfava.
2. Kuvandudzwa Kwekushanda: Nekuwedzera kushanda uye purasitiki yemusanganiswa wegypsum plaster, HEMC inofambisa nyore kuparadzira, kukwenya, uye kupera kwepurasita.Izvi zvinoguma mune imwe yunifomu uye inoyevedza nzvimbo.
3. Yakaderedzwa Sagging uye Shrinkage: HEMC inokwidziridza kubatana uye thixotropic zvimiro zvegypsum plaster, kuderedza njodzi yekudonha kana kudonha panguva yekunyorera uye kuderedza shrinkage kutsemuka sezvo plaster inomesa.
4. Enhanced Adhesion: HEMC inosimudzira kunamatira kuri nani kwegypsum plaster kune akasiyana substrates, anosanganisira masonry, kongiri, drywall, uye iripo plaster nzvimbo.Izvi zvinovandudza iyo yakazara chisungo simba uye kusimba kweiyo plaster kupera.
5. Inodzorwa Kugadzika Nguva: HEMC inogona kubatsira kudzora nguva yekugadzika yegypsum plaster, ichibvumira kugadziridzwa kuti ienderane nezvinodiwa zvekushandisa uye mamiriro ezvakatipoteredza.Izvi zvinovimbisa yakakwana nguva yekushanda uye inobvumira kupora kwakaringana kwepurasita.
6. Yakavandudzwa Mechanical Properties: Kubatanidza HEMC mune gypsum plaster maumbirwo anogona kukwidziridza zvimisikidzo zveiyo yakaomeswa plaster, kusanganisira kumanikidza simba, flexural simba, uye kukanganisa kuramba.
7. Yakaderedzwa Hupfu uye Kukoromoka: HEMC inobatsira kudzikisa guruva uye kudonha kwegypsum plaster nzvimbo nekupa kubatana kukuru uye kusimba kune plaster matrix.Izvi zvinoguma nekupera kwakapfava uye kwakasimba kusinganyanyi kukuvara.

HEMC inoshanda seyakakosha mashandiro ekuwedzera mune gypsum plaster maumbirwo, ichipa mabhenefiti akadai sekuvandudza kushanda, kuchengetedza mvura, kunamatira, uye kusimba.Kushandiswa kwaro kunobatsira mukugadzirwa kwemhando yepamusoro plaster inopera ine yakawedzera zvivakwa uye maitiro ekuita.
