PVC k57 ya WPC
PVC k57 ya WPC,
PVC utomoni kwa thovu bolodi, PVC utomoni kwa WPC pansi,
WPC - WOOD PLASTIC COMPOSITE , ndi gulu lamatabwa ndi pulasitiki.Poyambirira, mankhwalawa ankagwiritsidwa ntchito pazithunzi zamkati ndi zakunja, zomwe makamaka zimagwira ntchito yokongoletsera.Pambuyo pake, idagwiritsidwa ntchito popanga pansi m'nyumba, koma 99% yazinthu zoyambira (pachimake) zomwe zimagwiritsidwa ntchito pamsika wamkati (wpc yazoyala pansi) ndi PVC + miyala ya ufa (calcium carbonate) (ndiko kuti, zopangidwa ndi thovu la PVC), kotero izo sizingatchulidwe kuti zopangidwa ndi WPC.Maonekedwe azinthu zenizeni za WPC ndizabwinoko kuposa zinthu wamba za thovu la PVC, koma ukadaulo wokonza ndizovuta, chifukwa chake msika nthawi zambiri umakhala zopangidwa ndi thovu la PVC.
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.
Gawo S-700Amagwiritsidwa ntchito makamaka popanga mapepala owonekera, ndipo amatha kukulungidwa kukhala mapepala olimba komanso osasunthika a phukusi, zinthu zapansi, filimu yolimba yopangira maswiti (mapepala opaka maswiti kapena filimu yonyamula ndudu), ndi zina zotero. filimu yolimba pang'ono, pepala, kapena kapamwamba kowoneka bwino kwa phukusi.Kapena ikhoza kubayidwa kuti ipange zolumikizira, ma valve, zida zamagetsi, zida zamagalimoto ndi zotengera.
