Kodi Polyvinyl chloride (PVC) phala la Resin ndi chiyani?

Utomoni wa polyvinyl chloride (PVC)Monga momwe dzinalo likusonyezera, utomoni uwu umagwiritsidwa ntchito makamaka ngati phala. Anthu nthawi zambiri amagwiritsa ntchito mtundu uwu wa phala ngati plastisol, womwe ndi mtundu wapadera wamadzimadzi wa pulasitiki ya PVC yomwe sinakonzedwe. . Ma phala nthawi zambiri amakonzedwa pogwiritsa ntchito njira za emulsion ndi micro-suspension.

Utomoni wa polyvinyl chloride paste uli ndi tinthu tating'onoting'ono tochepa, ndipo kapangidwe kake ndi kofanana ndi talc, kosasuntha. Utomoni wa polyvinyl chloride paste umasakanizidwa ndi Plasticizer kenako n’kusunthidwa kuti upange suspension yokhazikika, yomwe kenako imapangidwa kukhala PVC paste, kapena PVC plastisol, PVC sol, ndipo ndi mu mawonekedwe awa momwe anthu amagwiritsidwa ntchito pokonza Zogulitsa zomaliza. Pakupanga phala, zodzaza zosiyanasiyana, zosungunulira, zolimbitsa kutentha, zotulutsa thovu ndi zolimbitsa kuwala zimawonjezedwa malinga ndi zosowa za zinthu zosiyanasiyana.

Kukula kwa makampani opanga utomoni wa PVC kumapereka mtundu watsopano wa zinthu zamadzimadzi zomwe zimakhala chinthu cha polyvinyl chloride pokhapokha ngati zatenthedwa. Mtundu uwu wa zinthu zamadzimadzi ndi wosavuta kuyika, wokhazikika pakugwira ntchito, wosavuta kuwongolera, wosavuta kugwiritsa ntchito, wabwino kwambiri pakugwira ntchito kwazinthu, wabwino pakukhala wokhazikika kwa mankhwala, uli ndi mphamvu inayake yamakina, wosavuta kupaka utoto, ndi zina zotero, kotero umagwiritsidwa ntchito kwambiri pa zikopa zopanga, zoseweretsa za vinyl, zizindikiro zofewa, Kupanga mapepala ophimba, utoto ndi zokutira, mapulasitiki okhala ndi thovu, ndi zina zotero.

Katundu：

Utomoni wa PVC paste (PVC) ndi gulu lalikulu la ma resini a polyvinyl chloride. Poyerekeza ndi ma resini osungunuka, ndi ufa wosungunuka kwambiri. Kukula kwa tinthu tating'onoting'ono nthawi zambiri kumakhala 0.1 ~ 2.0μm (kufalikira kwa tinthu tating'onoting'ono ta ma resini osungunuka nthawi zambiri kumakhala 20 ~ 200μm). Utomoni wa PVC paste unafufuzidwa ku fakitale ya IG Farben ku Germany mu 1931, ndipo kupanga mafakitale kunapangidwa mu 1937.

M'zaka makumi asanu zapitazi, makampani opanga ma PVC Resin padziko lonse lapansi apita patsogolo mofulumira. Makamaka m'zaka khumi zapitazi, mphamvu zopangira ndi kutulutsa zinthu zawonetsa kukula kwakukulu, makamaka ku Asia. Mu 2008, mphamvu zonse zopangira ma PVC resin padziko lonse lapansi zinali pafupifupi matani 3.742 miliyoni pachaka, ndipo mphamvu zonse zopangira ku Asia zinali pafupifupi matani 918,000, zomwe zimapangitsa 24.5% ya mphamvu zonse zopangira. China ndi dera lomwe likukula mwachangu kwambiri mumakampani opanga ma PVC resin, ndipo mphamvu zopangira zinthu zimakhala pafupifupi 13.4% ya mphamvu zonse zopangira padziko lonse lapansi komanso pafupifupi 57.6% ya mphamvu zonse zopangira ku Asia. Ndiwo wopanga wamkulu kwambiri ku Asia. Mu 2008, mphamvu zonse zopangira ma PVC resin padziko lonse lapansi zinali pafupifupi matani 3.09 miliyoni, ndipo mphamvu zonse zopangira zinthu ku China zinali matani 380,000, zomwe zimapangitsa pafupifupi 12.3% ya mphamvu zonse zopangira padziko lonse lapansi. Mphamvu zopangira ndi kutulutsa zinthu zili pa nambala 3 padziko lonse lapansi.
