Faahfaahinta alaabta
PVC waa erey la soo gaabiyay oo loogu talagalay chloride polyvinyl.Xabagta waa shay inta badan loo isticmaalo soo saarista caagagga iyo caagadaha.Xabagta PVC waa budo cad oo caadi ahaan loo isticmaalo in lagu soo saaro heerkulbeegyada.Waa walxo synthetic ah oo si weyn looga isticmaalo adduunka maanta.Polyvinyl chloride resin waxa uu leeyahay sifooyin aad u wanaagsan sida alaab cayriin oo badan, tignoolajiyada wax soo saarka ee bislaaday, qiimo jaban, iyo adeegsiyeedyo kala duwan.Way fududahay in la farsameeyo waxaana lagu farsamayn karaa qaabaynta, laminating, qaabaynta duritaanka, extrusion, calending, dharbaaxada qaabaynta iyo habab kale.Iyada oo leh astaamo jireed iyo kiimiko oo wanaagsan, waxaa si weyn loogu isticmaalaa warshadaha, dhismaha, beeraha, nolol maalmeedka, baakadaha, korontada, adeegyada dadweynaha, iyo beeraha kale.Xabagta PVC waxay guud ahaan leeyihiin iska caabin kiimiko oo sarreeya.Aad bay u xoog badan tahay oo u adkaysataa biyaha iyo naaxinta.Polyvinyl chloride resin (PVC) waxaa lagu farsamayn karaa baco kala duwan.PVC waa balaastiig khafiif ah, raqiis ah, oo deegaanka u wanaagsan.
Astaamaha
PVC waa mid ka mid ah resins thermoplastic ee ugu isticmaalka badan.Waxaa loo isticmaali karaa in lagu sameeyo alaab adag oo adag, sida tuubooyinka iyo qalabka wax lagu dhejiyo, albaabada muuqaalkooda leh, daaqadaha iyo baakadaha.Waxa kale oo ay samayn kartaa alaabo jilicsan, sida filimaan, go'yaal, fiilooyinka korantada iyo fiilooyinka, sagxadaha sagxadaha iyo maqaarka synthetic, iyada oo lagu daro caagadaha.
