Polyvinyl chloride resin S-700
Polyvinyl Chloride, inonzi PVC, ndeimwe yemhando dzepurasitiki dzakagadzirwa, iyo yazvino inobuda ndeyechipiri kune polyethylene.Polyvinyl chloride yakashandiswa zvakanyanya muindasitiri, kurima uye hupenyu hwezuva nezuva.Polyvinyl chloride inhengo yepolymer yakagadzirwa nevinyl chloride.Inonzi thermoplastic.Upfu huchena kana huyero hwakareruka.Inonyungudika mumaketone, esters, tetrahydrofurans uye mahydrocarboni ane chlorinated.Excellent chemical resistance.Kusagadzikana kwemafuta uye kushomeka kwechiedza, kupfuura 100 ℃ kana kuratidzwa kwenguva refu kuchiedza chezuva kwakatanga kuora hydrogen chloride, kugadzira mapurasitiki kunoda kuwedzera stabilizer.Kuiswa kwemagetsi kwakanaka, hakupise.
Giredhi S-700inonyanya kushandiswa kugadzira mapepa akajeka, uye anogona kukungurutswa kuita akaomesesa uye semi-akaomesesa mapepa epasuru, zvinhu zvepasi, firimu rakaoma rekuisa (yepepa rekupeta zvihwitsi kana firimu rekutakura fodya), nezvimwe. Inogona zvakare kuburitswa kune yakaoma kana semi-yakaoma firimu, shizha, kana isina kurongeka bhaa repasuru.Kana kuti inogona kubaiwa kuti igadzire majoini, mavharuvhu, zvikamu zvemagetsi, auto accessories uye midziyo.
