PVC SG-8
PVC SG-8,
uwea auwai maka mea, Hoʻohana ʻia ʻo PVC SG-8 no ka hana ʻana i nā pā pā,
ʻO ka polymer kiʻekiʻe-molecular thermoplastic i hana ʻia e ka polymerization suspension o ka monomer vinyl chloride.ʻO ke ʻano molekole:- (CH2 – CHCl) n – (N: degere o ka polymerization, N= 590 ~ 1500).ʻO ia ka mea i hoʻohana nui ʻia i ka hana plastic.Loaʻa iā ia ke kūpaʻa kemika maikaʻi, ka pale ʻana i ka corrosion a me ka pale wai.

Nā noi
ʻO ka polyvinyl chloride resin ka nui o nā noi, e like me nā kaʻa i loko, nā mea hoʻonaninani ʻohana, ka pahu kukui hoʻolaha, nā kāmaʻa, nā paipu PVC a me nā mea pono, nā profile PVC a me ka hose, ka pepa PVC a me ka pā, ke kiʻi ʻoniʻoni, nā mea pāʻani inflatable, nā huahana waho, PVC uea a me ka uwea, PVC ili hana, laau a me ka palaka papahele, corrugated papa, etc.
Hoʻopili ʻia
25kg liner eke liner me PE
wehewehe:
ʻO ka hiʻohiʻona PVC SG-8 he pauka keʻokeʻo homogeneous, me ka ʻono ʻole a me ka ʻala.
ʻO ka hoʻohana ʻana o PVC resin brand SG-8:
Hoʻohana ʻia ʻo Resin brand SG-8 no ka hana ʻana i nā moldings profiled thin-walled moldings, wall panels, cable ducts, semi-rigid products of General purpose (linoleum, artificial leather, plasticized films, three-dimensional polymer packaging).
Hana hana:
Loaʻa ma ka polymerization o ka vinyl chloride.Lawe ʻia ka polymerization i ka hoʻokuʻu ʻia (i ka wai wai).
Nui nā ʻano hana e hana ai i ka vinyl chloride mai acetylene, ethylene dichloride, ethylene a me ethane.Hoʻokumu wale ʻia kā mākou huahana ma ka hoʻohana ʻana i ka ethylene.
