Chii chinonzi Gypsum Hand Plaster?

Gypsum hand plaster chinhu chekuvaka chinoshandiswa mukati mekupera kwemadziro. Musanganiswa wegypsum, aggregates, uye zvimwe zvinowedzera, uye inoshandiswa nemaoko nevashandi vane hunyanzvi vachishandisa maturusi emaoko. Iyo plaster inoroverwa pamusoro pemadziro, ichigadzira yakatsetseka uye kunyange kupera iyo inogona kusiiwa sezvairi kana kupendwa pamusoro.

Gypsum, chinhu chikuru chekugadzira gypsum hand plaster, iminerari inongoitika inocherwa kubva mudhipoziti pasi. Icho chinhu chakapfava uye chichena chinoputika nyore nyore kuita upfu. Kana yasanganiswa nemvura, gypsum inoumba paste inoomesa kuita chinhu chakasimba. Ichi chivakwa chinoita kuti chive chinhu chakakodzera chekupurasita.

Aggregates, akadai sejecha kana perlite, anowedzerwa kune gypsum plaster musanganiswa kuti ivandudze kushanda kwayo, kuderedza shrinkage uye kuputika, uye kunatsiridza kupisa kwayo uye acoustic insulation zvimiro. Zvimwe zvinowedzera, senge cellulose fibers kana air-entraining agents, zvinogonawo kuwedzerwa kuvandudza simba repurasita uye kusimba.

Gypsum hand plaster chinhu chakasiyana-siyana chinogona kushandiswa kune akasiyana emukati emadziro kupera. Inogona kuiswa kune chero nzvimbo yakachena, yakaoma, uye inonzwika, kusanganisira kongiri, masonry, kana plasterboard. Iyo plaster inogona kushandiswa kugadzira yakatsetseka kana yakashongedzwa kupera, zvichienderana nechitarisiko chaunoda.

Imwe yemabhenefiti egypsum hand plaster ndiyo inodzivirira moto. Gypsum chinhu chakasikwa chisingadziviriri moto chinogona kubatsira kudzivirira kupararira kwemoto kana moto wabvira. Izvi zvinoita kuti ive sarudzo yakakurumbira yezvivakwa zvekutengesa uye zveveruzhinji, uko kuchengetedzwa kwemoto kuri kunetseka.

Imwe mukana we gypsum hand plaster ndeye nyore kushandisa. Kusiyana nemapurasita anoiswa muchina, anoda midziyo yakasarudzika, gypsum hand plaster inogona kuiswa nemaoko uchishandisa maturusi emaoko ari nyore. Izvi zvinoita kuti ive mhinduro inodhura yemapurojekiti madiki kana nzvimbo dzinonetsa kuwana.

Cellulose ether, kune rumwe rutivi, ipolymer inonyungudika nemvura inotorwa kubva kune yakasikwa cellulose. Inowanzo shandiswa mu gypsum hand plaster sechinhu chinowedzera kuvandudza kushanda kwechinyorwa uye kushanda.

Cellulose ether inowedzerwa kune gypsum plaster musanganiswa kuti ivandudze zvimiro zvayo zvakadai sekuchengetedza mvura, kunamatira, uye kushanda. Inoita seyakasvibirira, ichibvumira plaster kuti ipararire nyore uye yakaenzana pamusoro pepamusoro, ichideredza kuputika nekuvandudza chitarisiko chayo chose. Inoitawo sebhainda, inobata musanganiswa pamwe chete nekuvandudza kunamatira kwayo kumusoro.

Iyo yekuchengeta mvura ye cellulose ether inonyanya kukosha mugypsum hand plaster. Gypsum plaster inoda humwe hunyoro hwehunyoro kuti uwane kugadzika kwakakodzera uye kuomesa. Pasina kuchengetwa kwemvura kwakakodzera, iyo plaster inogona kuoma nekukurumidza, zvichikonzera kuputika, kuputika, uye zvimwe zvikanganiso. Cellulose ether inobatsira kuchengetedza mvura mumusanganiswa wepurasita, kunonoka kuomeswa uye kuona kuti plaster inogadzika zvakanaka.

Pamusoro pekuchengetedza mvura uye kukora, cellulose ether inogona zvakare kuvandudza iyo inopisa uye acoustic insulation zvimiro zvegypsum hand plaster. Nekuwedzera cellulose fiber kumusanganiswa, iyo plaster inogona kupa zvirinani kunyura uye kuvharisa, kuvandudza kunyaradza kwese uye kushanda nesimba kwechivako.

Sarudzo uye huwandu hwe cellulose ether yakawedzerwa kune gypsum hand plaster inogona kukanganisa zvakanyanya kuita kwayo uye kushanda kwayo. Mhando dzakasiyana dze cellulose ether dziripo, dzakadai sehydroxyethyl cellulose (HEC), methyl cellulose (MC), uye carboxymethyl cellulose (CMC), imwe neimwe iine hunhu hwayo uye maitiro. Rudzi uye huwandu hwe cellulose ether yakawedzerwa kumusanganiswa weplaster inofanira kunyatsosarudzwa zvichienderana nezvinodiwa zveprojekiti.

Muchidimbu, gypsum hand plaster chinhu chekuvaka chinoshandiswa mukati memadziro kupera. Musanganiswa wegypsum, aggregates, uye zvimwe zvinowedzera, uye inoshandiswa nemaoko nevashandi vane hunyanzvi vachishandisa maturusi emaoko. Gypsum hand plaster haidziviriri moto, iri nyore kuisa, uye inogona kushandiswa kugadzira magumo akasiyana.
