PVC ndi PP

kusiyana pakati pa PP ndi PVC mosasamala kanthu za maonekedwe kapena kumva kungakhale kosiyana kwambiri; Kumverera kwa PP kumakhala kolimba ndipo PVC ndi yofewa.

PP ndi thermoplastic resin wokonzedwa ndi polymerization wa propylene. Pali masanjidwe atatu a isochronous, osalamuliridwa komanso ma interchronous, ndipo zinthu za isochronous ndizo zigawo zazikulu zazinthu zamakampani. Polypropylene imaphatikizansopo ma copolymers a propylene ndi ethylene pang'ono. Nthawi zambiri translucent colorless olimba, fungo osati poizoni.

Zomwe zili: zopanda poizoni, zopanda pake, zochepa kwambiri, mphamvu, kuuma, kuuma ndi kukana kutentha kuli bwino kuposa polyethylene yotsika kwambiri, ingagwiritsidwe ntchito pa madigiri 100 kapena kuposerapo. Good magetsi katundu ndi mkulu pafupipafupi kutchinjiriza sizimakhudzidwa ndi chinyezi, koma amakhala Chimaona pa kutentha otsika, osati kuvala kugonjetsedwa, zosavuta kukalamba. Zoyenera kupanga mawotchi ambiri, zida zolimbana ndi dzimbiri komanso zida zotchinjiriza.

PVC ndi imodzi mwazinthu zazikulu kwambiri padziko lonse lapansi zopangidwa ndi pulasitiki, zotsika mtengo, zogwiritsidwa ntchito kwambiri, utomoni wa polyvinyl chloride ndi ufa woyera kapena wopepuka wachikasu. Zowonjezera zosiyanasiyana zitha kuwonjezeredwa molingana ndi NTCHITO zosiyanasiyana, ndipo mapulasitiki a polyvinyl chloride ali ndi mawonekedwe osiyanasiyana akuthupi komanso amakina. Kuwonjezera pulasitiki yoyenera mu polychlorethylene resin ikhoza kupangidwa kukhala zinthu zosiyanasiyana zolimba, zofewa komanso zowonekera. Kuchulukana kwa PCC koyera ndi 1.4g/cm3, ndipo kachulukidwe ka PCC plasticizers ndi fillers zambiri 1.15-2.00g/cm3. POLYchlorethylene yolimba imakhala yabwino kumakoka, kusinthasintha, kuponderezana komanso kukana ndipo imatha kugwiritsidwa ntchito ngati zinthu zomangika zokha.
