PVC S-700
PVC S-700,
akajeka mapepa PVC resin,
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-700 inonyanya kushandiswa kugadzira maflakes akajeka, uye inogona kudzvanywa kune yakaoma kana semi-yakaoma chidimbu kana pepa repasuru, zvinhu zvepasi, firimu rakaoma rekugadzira (yepepa rekupeta zvihwitsi kana firimu rekutakura fodya), nezvimwe. Inogona. wedzerawo kune yakaoma kana semi-yakaoma chidimbu, shizha, kana isina kurongeka bhaa yepasuru.Kana kuti inogona kubaiwa kuti igadzire majoini, mavharuvhu, zvikamu zvemagetsi, auto accessories uye midziyo.
