mutsauko pakati pePP nePVC zvisinei nechitarisiko kana kunzwa unogona kunge wakasiyana zvakanyanya; PP inonzwa yakaoma uye PVC yakapfava.
PP is thermoplastic resin yakagadzirwa nepolymerization yepropylene. Kune matatu magadzirirwo eisochronous, asina kunyoreswa uye interchronous zvigadzirwa, uye isochronous zvigadzirwa ndizvo zvakakosha zvezvigadzirwa zveindasitiri. Polypropylene inosanganisirawo copolymers yepropylene uye shoma shoma ye ethylene. Kazhinji translucent isina ruvara yakasimba, isina hwema isina chepfu.
Zvimiro: kwete-chepfu, isina kunaka, yakaderera density, simba, kuoma, kuoma uye kupisa kupisa zviri nani pane kuderera kwepolyethylene, inogona kushandiswa pa 100 degrees kana zvakadaro. Zvakanaka zvemagetsi zvivakwa uye yakakwirira frequency insulation haikanganiswe nehunyoro, asi inove brittle pakudziya kwakadzika, kwete kupfeka kusagadzikana, nyore kuchembera. Inokodzera kugadzira general mechanical parts, corrosion resistant parts uye insulation parts.
PVC ndeimwe yepasirese kugadzirwa kwezvigadzirwa zvepurasitiki, zvakachipa, zvakashandiswa zvakanyanya, polyvinyl chloride resin ichena kana light yellow powder. Zvimwe zvinowedzera zvinogona kuwedzerwa zvichienderana neUSES dzakasiyana, uye polyvinyl chloride mapurasitiki ane akasiyana emuviri uye emuchina zvinhu. Kuwedzera yakakodzera plasticizer mu polychlorethylene resin inogona kugadzirwa mumhando dzakasiyana dzakaoma, dzakapfava uye dzakajeka zvigadzirwa. Kuwanda kwePCC yakachena ndeye 1.4g/cm3, uye kuwanda kwePCC plasticizers uye mafirita anowanzo 1.15-2.00g/cm3. Yakaoma POLYchlorethylene ine yakanaka tensile, flexural, compressive uye kukanganisa kuramba uye inogona kushandiswa seyakaumbwa zvinhu chete.
