No ka maikaʻi o ka resin pvc i ke kino, kemika, ka uila, ke ahi retardant hana, i nā 1930s a me 40s, ua hoʻomaka nā haole e hoʻohana i ka PVC palupalu e like me ka mea hoʻokalakupua no ka uea, hoʻomaka ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea uwea PVC ma Kina i ka makahiki 1950.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.

Hoʻokumu ʻia nā mea kelepona PVC me ka resin polyvinyl chloride, stabilizer, plasticizer, filler, lubricant, antioxidant, colorant a pēlā aku.

ʻO PVC plastic ma muli o kona flammability, oil resistance, corona resistance, chemical corrosion resistance and good water resistance, no laila ua hoʻohana nui ʻia ʻo ia i mea pale no nā uea a me nā kaula.Ma ka hoʻohui ʻana i nā mea hoʻohui kūikawā a i ʻole nā ​​mea hoʻololi, pale wela (105 ℃), pale anuanu, pale ʻaila, pale ahi, ʻoi aku ka palupalu a me nā mea ʻawaʻawa PVC hiki ke hana ʻia i kēlā me kēia no ka hoʻokō ʻana i nā pono o nā uea kūikawā a me nā huahana kelepona.

Ma ka hoʻohui ʻana i nā mea hoʻohui kūikawā a i ʻole nā ​​mea hoʻololi, pale wela (105 ℃), pale anuanu, pale ʻaila, pale ahi, ʻoi aku ka palupalu a me nā mea ʻawaʻawa PVC hiki ke hana ʻia i kēlā me kēia no ka hoʻokō ʻana i nā pono o nā uea kūikawā a me nā huahana kelepona.

ʻO ka polyvinyl chloride (PVC) plastic he plastic multi-component, e like me nā kūlana like ʻole o ka hoʻohana ʻana, ma ka hoʻololi ʻana i ke ʻano a me ke ʻano o ka mea paʻakikī, hiki ke hana ʻia i nā ʻano like ʻole o ka plastik PVC no ka uea a me ke kaula.Polyvinyl chloride (PVC) uwea plastic e like me kona hoohana ana i ka uwea a me ka uwea, hiki ke maheleia i ka insulation level cable material and protective level cable material.Pono ka pae palekana i ka pale wela maikaʻi, a ʻo ka pae insulation e pono ai ka insulation maikaʻi.

E hoʻohana i ka hoʻohālikelike

Hiki ke hoʻokaʻawale ʻia nā mea uila PVC i:

PVC insulated uwea mea

ʻO nā mea uwea puʻupuʻu PVC

ʻO nā mea uwea i hoʻopaʻa ʻia i ka lapalapa ahi PVC

ʻO nā mea uwea puʻupuʻu PVC pale ahi

ʻO nā mea uwea PVC elastomer

ʻO ke kaula i hoʻopaʻa ʻia ma waho o PVC
