PVC RESIN NO KE KAPU
PVC RESIN NO KE KAPU,
Pahu Uea PVC, ʻO ke Uila PVC Mea Maka, PVC No na Uea Uila, ʻO ka resin PVC no ka hoʻopili ʻana i ke kaula,
PVC no ka mea he maikai kino, kemika, uila, ahi retardant hana, i ka 1930s a me 40s, haole hoʻomaka e hoʻohana palupalu PVC e like me ka insulation mea no ka uea, ka hooulu ana a me ka hoʻohana 'ana o PVC uwea mea i loko o ko kakou aina hoʻomaka i ka 1950s.Me ka hoʻomaikaʻi ʻana i ka mana hana o ka resin PVC, plasticizer a me nā mea hoʻohui ʻenehana a me ka hoʻolaha ʻana a me ka hoʻohana ʻana i nā ʻano hou, ua loaʻa i ka ʻoihana kelepona kahi lele qualitative.
I ke kenekulia 21, me ka hoʻonui ʻana i ka ʻike kaiapuni kanaka a me ka nānā ʻana o nā kānaka i ko lākou olakino ponoʻī, ua lilo nā pilikia kaiapuni i mea nui o ke kaiāulu kanaka.Nui nā ʻāina, nā ʻāpana a me nā hui i hoʻokumu i nā kūlana koʻikoʻi a me nā lula e kaupalena i ka hoʻohana ʻana i nā mea ʻino, ʻoi aku ka RolS a me nā kānāwai REACH.Ke ʻimi nei i nā ʻano hou a me nā kaʻina hana hou, hoʻomaikaʻi i ka hoʻohana ʻana i nā kumuwaiwai, hoʻololi i nā koi o nā kānāwai mālama kaiapuni a me nā hoʻoponopono, ʻike ʻia nā mea uila PVC palekana i kēia manawa, a lilo koke i hoʻokahi o nā kumumanaʻo o ka hoʻomohala ʻana i nā mea uila PVC o kēia manawa. .
ʻO ka piʻi ʻana o ka hoʻololi a me ka hoʻonui ʻana o ka mākeke noi no ka uea a me ke kaula (i kapa ʻia ʻo cable), a me ka noiʻi hohonu o nā mea hoʻohui hou (e like me ka flame retardant additives, smoke suppressor), e hāpai i ka hoʻolaha a me ka hoʻohana ʻana i nā mea hou. nāʻenehana, nā mea hou a me nā huahana hou o nā mea PVC.I loko o ka nui o nā mea kūlohelohe (e like me ka plastic, rubber) i hoʻohana ʻia i ka ʻoihana kelepona, ʻo ka nui o nā mea kelepona PVC ka mea mua o ko mākou ʻāina.
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.
