Yintoni kanye kanye iplastiki yeplastiki yePVC?

Ukwaziswa ngokutsha kweplastiki yeplastiki yePVC

I-PVC, igama elipheleleyo yiPolyvinylchlide, eyona nto iphambili yi-polyvinyl chloride, kwaye ezinye izinto zongezwa ukomeleza ukumelana nobushushu, ubunzima, njl njl.

Iingqengxe ezintathu  zeplastiki yePVC

Umaleko ophezulu we-PVC yi-lacquer, eyona nto iphambili embindini yi-polyvinyl chloride, kwaye umlinganiso ongezantsi ngumlinganiso ongasemva.

Ukusetyenziswa kwe-PVC ngokubanzi

Izinto ze-PVC yinto ethandwayo ethandwayo, ethandwayo neyokusetyenziswa ngokubanzi kwempahla yehlabathi namhlanje. Ukusetyenziswa kwayo kwehlabathi jikelele ngowesibini-upetha phakathi kwezinto zonke zokwakha. Ngokweenkcukacha-manani, ngo-1995 yedwa, ukuveliswa kwe-PVC eYurophu kwakumalunga neetoni ezi-5 ezizigidi, ngelixa ukusetyenziswa kwazo yayizi-5.3 zeetoni ezigidi. EJamani, iMveliso ye-PVC kunye nokusetyenziswa komndilili ophakathi 1.4 iitoni ezigidi. I-PVC iveliswa kwaye isetyenziswa kwihlabathi liphela kwinqanaba lokukhula kwe-4%. Ukukhula kwe-PVC e-PVC eMzantsi-mpuma yeAsia kubaluleke kakhulu, ngenxa yemfuno engxamisekileyo yolwakhiwo lwezibonelelo kumazwe ase-mpuma ase-mpuma. Phakathi kwezixhobo ezinokuthi zivelise iifilimu zomphezulu womhlaba, i-PVC yeyona nto ifanelekileyo.

Iindidi ezahlukeneyo zePlasitiki yePVC

I-PVC inokwahlulwa ibe yifilimu ye-PVC ethambileyo kunye nephepha le-PVID PVC. Phakathi kwawo, i-rigid pvc i-Akhawunti malunga ne-2/3 yemakethi, kunye ne-akhawunti ye-PVC ethambileyo ye-1/3. Ifilimu ethambileyo ye-PVC isetyenziswa ngokubanzi kumphezulu wamanqanaba, ukuqina, kunye nesikhumba. Kodwa ngenxa yokuba i-PVC ethambileyo iqulethe izithambiso, kulula ukuba ibe brittle kwaye kunzima ukugcina, ke ububanzi bayo bokusetyenziswa bulinganiselwe. Lo ngumahluko phakathi kwefilimu ye-pvc ethambileyo kunye nephepha eliqinileyo lePVC. Iphepha le-PVC le-PVC alifumananga nezithambiso, ngoko ke liguquguqukele kakuhle, kulula ukuseka, akukho lula ukuba yiBrittle, engenabungozi, kwaye ingenalo ixesha elide kugcino. Ngenxa yezibonelelo zayo ezibonakalayo, inamandla amakhulu kunye nexabiso lesicelo.
