PVC SG-8

whakaahuatanga poto:

Ko te polymer teitei-rolecular thermoplastic i hangaia e te polymerization whakatārewatanga o te monomer vinyl chloride.Te tātai rāpoi:- (CH2 – CHCl) n – (N: tohu o te polymerization, N= 590 ~ 1500).Ko te rauemi mata tino whanui e whakamahia ana ki te hanga kirihou.He pai te pumau matū, te aukati waikura me te aukati wai.

Whakaahuatanga:
Ko te ahua o te PVC SG-8 he paura ma, kaore he reka me te kakara.

Ko te whakamahi o te PVC resin waitohu SG-8:
Ka whakamahia te waitohu Resin SG-8 mo te hanga moldings profiled angiangi-taiepa, awhi pakitara, awa taura, hua āhua-mārō o te whakaaro Whānui (linoleum, hiako horihori, kiriata kirihou, toru-ahu polymer tākai).

Tikanga whakaputa:
I whiwhi i te polymerization o te vinyl chloride.Ka mahia te polymerization i roto i te aukati (i roto i te taiao wai).
He maha nga tikanga mo te whakaputa vinyl chloride mai i te acetylene, te ethylene dichloride, te ethylene me te ethane.Ko o maatau hua kei runga noa i te whakamahinga o te ethylene.
