PVC SG-8
PVC SG-8,
tuubooyinka fiilooyinka alaabada ceeriin, PVC SG-8 loo isticmaalo soo saarista darfaha derbiga,
Polymerka-molecular-ku-sare ee heerkulbeegga ah ee uu sameeyay polymerization-ka joojinta ee monomer-ka vinyl chloride.Qaabka molecular:- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500).Waa alaabta ceeriin ee ugu ballaaran ee loo isticmaalo wax soo saarka caagga ah.Waxay leedahay xasillooni kiimikaad oo wanaagsan, iska caabbinta daxalka iyo iska caabinta biyaha.

Codsiyada
Polyvinyl chloride resin wuxuu leeyahay codsiyo kala duwan oo kala duwan, sida gudaha baabuurta, alaabta qurxinta qoyska, sanduuqa iftiinka xayeysiiska, kabaha kabaha, tuubooyinka PVC iyo qalabka, profiles PVC iyo tuubada, xaashida PVC iyo saxanka, filimka duubista, alaabta lagu ciyaaro ee la buufiyo, alaabta dibadda, Xadhkaha PVC-ga iyo fiilada, PVC maqaar macmal ah, alwaax iyo dabaq balaastig ah, looxa jiingado, iwm.
Baakadaha
25kg shandad farshaxan oo leh PE
Sharaxaad:
Muuqaalka PVC SG-8 waa budo cad oo isku mid ah, oo aan lahayn dhadhamin iyo ur.
Isticmaalka caarada PVC ee SG-8:
Calaamadda Resin SG-8 waxaa loo isticmaalaa soo saarista qaab-dhismeedyo khafiif ah oo dhuuban, darbiyada gidaarka, fiilooyinka fiilooyinka, alaabooyinka adag ee ujeedada guud (linoleum, maqaar macmal ah, filimo caag ah, baakad polymer saddex-cabbir ah).
Habka wax soo saarka:
Lagu helay polymerization of vinyl chloride.Polymerization-ka waxaa lagu fuliyaa hakin (ee deegaanka biyaha).
Waxaa jira habab badan oo lagu soo saaro chloride vinyl ka acetylene, ethylene dichloride, ethylene iyo ethane.Alaabtayadu waxay ku saleysan yihiin oo keliya isticmaalka ethylene.
