Mea mata mo le saunia o paipa PVC malu puipui lua
Mea mata mo le saunia o paipa PVC malu puipui lua,
Mea mata e gaosia ai paipa PVC puipui lua,
O le Polyvinyl Chloride (PVC) o se resini thermoplastic laina e gaosia e le polymerization o le monomer vinyl chloride.Ona o le eseesega o mea mata, e lua auala o le synthesizing vinyl chloride monomer calcium carbide process ma le suauu.Sinopec PVC faʻaaogaina faiga faʻamalolo se lua, mai le Kamupani Iapani Shin-Etsu Chemical ma American Oxy Vinyls Company.O le oloa o lo'o i ai le lelei o le fa'a'a'ala'au fa'ama'i, mea fa'amama eletise lelei ma le mautu lelei o vaila'au.Faatasi ai ma le maualuga o le chlorine, o le meafaitino e lelei le afi ma mea e tineia ai le tagata lava ia.O le PVC e faigofie ona faʻaogaina e ala i le faʻafefe, tui tui, calendering, faʻafefeteina, faʻamalosi, faʻafefeteina ma le vevela, ma isi.
Fa'atatauga
PVC o se tasi o resins thermoplastic sili ona faʻaaogaina.E mafai ona faʻaaogaina e fai ai oloa e maualuga le maaa ma le malosi, e pei o paipa ma mea faʻapipiʻi, faitotoa faʻailoga, faamalama ma laupepa afifi.
E mafai foʻi ona fai mea vaivai, e pei o ata tifaga, laupepa, uaea eletise ma uaea, laupapa fola ma paʻu synthetic, e ala i le faʻaopoopoga o mea faʻapipiʻi.
