Pipa polivinil klorida kelas
Polyvinyl Chloride (PVC) minangka resin termoplastik linier sing diprodhuksi dening polimerisasi monomer vinil klorida.Amarga bedane bahan mentah, ana rong cara sintesis vinyl klorida monomer kalsium karbida proses lan proses petroleum.Sinopec PVC nganggo rong proses suspensi, masing-masing saka Perusahaan Kimia Shin-Etsu Jepang lan Perusahaan Vinyl Oxy Amerika.Produk kasebut nduweni resistensi korosi kimia sing apik, sifat insulasi listrik sing apik lan stabilitas kimia sing apik.Kanthi kandungan klorin sing dhuwur, materi kasebut nduweni retardance geni sing apik lan sifat-sifat pemadam dhewe.PVC iku gampang kanggo proses dening extrusion, ngecor injeksi, calendering, jotosan ngecor, compressing, cast ngecor lan ngecor termal, etc.
Aplikasi
PVC minangka salah sawijining resin termoplastik sing paling akeh digunakake.Bisa digunakake kanggo nggawe produk kanthi kekerasan lan kekuwatan sing dhuwur, kayata pipa lan fitting, lawang profil, jendhela lan lembaran kemasan.
Uga bisa nggawe produk alus, kayata film, sheets, kabel listrik lan kabel, floorboards lan kulit sintetis, kanthi tambahan plasticizers.
Pvc resin pipe bahan iki digunakake digunakake ing pipe got, pipo irigasi, bellows, pipo kalen, produksi pipe threading.
