PVC S-700
PVC S-700,
mandala mapepala PVC utomoni,
Polyvinyl Chloride, wotchedwa PVC, ndi imodzi mwa mitundu ya pulasitiki yopangidwa ndi mafakitale, zomwe zilipo panopa ndi zachiwiri kwa polyethylene.Polyvinyl chloride yakhala ikugwiritsidwa ntchito kwambiri m'makampani, ulimi komanso moyo watsiku ndi tsiku.Polyvinyl chloride ndi polima pawiri polymerized ndi vinilu kloride.Ndi thermoplastic.ufa woyera kapena wopepuka wachikasu. Amasungunuka mu ketoni, esters, tetrahydrofurans ndi ma hydrocarboni a chlorine.Wabwino kukana mankhwala.Kusakhazikika kwamafuta ndi kukana kuwala, kupitilira 100 ℃ kapena kutentha kwa nthawi yayitali kudayamba kuwola hydrogen chloride, kupanga pulasitiki kumafunika kuwonjezera stabilizer.Kutsekemera kwamagetsi ndikwabwino, sikungawotche.
Gulu la S-700 limagwiritsidwa ntchito makamaka popanga ma flakes owoneka bwino, ndipo imatha kukanikizidwa ku kagawo kolimba kapena kolimba kwambiri kapena pepala la phukusi, zinthu zapansi, filimu yolimba yolumikizira (papepala lomata maswiti kapena filimu yonyamula ndudu), ndi zina zotero. onjezeraninso ku kagawo kolimba kapena kolimba, pepala, kapena kapamwamba kosaoneka bwino kwa phukusi.Kapena ikhoza kubayidwa kuti ipange zolumikizira, ma valve, zida zamagetsi, zida zamagalimoto ndi zotengera.
