A: Meatotino Polyvinyl chloride o loʻo faʻapipiʻiina mole mole maualuga polymerized e vinyl chloride monomer (VCM) faʻatasi ai ma elemene faʻavae e pei o CH2-CHCLn, tikeri o le polymerization masani e pei o le 590-1500. I le faagasologa o le toe faʻafouina, e aʻafia i ituaiga mea e pei o le faiga polymerization, tulaga tali, reactant composition, additives etc.it e mafai ona maua ituaiga eseese e valu o PVC resin faatinoga e ese.E tusa ai ma mea o totoe o le vinyl chloride i polyvinyl chloride resin, e mafai ona vaevaeina i: vasega pisinisi, tulaga tumama meaai ma vasega talosaga faafomai i foliga vaaia, polyvinyl chloride resin o le paʻepaʻe paʻepaʻe po o pellet.
B: Talosaga Polyvinyl chloride resin o loʻo faʻaaogaina lautele i le gaosiga o le polyvinyl chloride boardy leatheroid, vali ma mea faʻapipiʻi, tec.Vali ma fa'apipi'i . Vaevaega e tusa ai ma le fa'aoga:
1. Faufale mea: pei o UPVC tubing, UPVC paipa, laulau ma vaega pa.
2. Mea fa'apipi'i.
3. Mea faʻaeletonika: e pei o uaea eletise, uaea, faʻamau faʻapipiʻi ma faʻamau.
4. Meafale ma mea teuteu, ma isi.
5.Others: leatheroid, oloa faʻaaogaina faʻafomaʻi, vali faʻamaʻi, ma isi.
