PVC SG-8
PVC SG-8,
uaea ala mea mata, PVC SG-8 faʻaaogaina mo le gaosiga o puipui puipui,
O le thermoplastic high-molecular polymer na faia e le polymerization taofia o le vinyl chloride monomer.Ole fua ole mole :- (CH2 – CHCl) n – (N: tikeri o le polymerization, N= 590 ~ 1500).O le mea sili ona fa'aaogaina i le gaosiga o palasitika.E lelei le mautu kemikolo, corrosion tetee ma vai tetee.

Fa'amatalaga:
Fa'aaliga PVC SG-8 o se pa'epa'e pa'epa'e tutusa, e aunoa ma se tofo ma sogisogi.
Le faʻaogaina o le PVC resin brand SG-8:
Resin brand SG-8 o loʻo faʻaaogaina mo le gaosiga o faʻamaufaʻailoga manifinifi puipui, puipui puipui, alavai uaea, oloa semi-malosi o le faʻamoemoe lautele (linoleum, paʻu paʻu, ata palasitika, faʻapipiʻi polymer tolu-dimensional).
Gaosiga auala:
Maua i le polymerization o le vinyl chloride.O le polymerization o loʻo faia i le faʻamalolo (i totonu o le vai).
E tele auala e gaosia ai le vinyl chloride mai le acetylene, ethylene dichloride, ethylene ma le ethane.O a matou oloa e faʻavae naʻo le faʻaaogaina o le ethylene.
