    ʻO ke ʻano o ka PVC, ke ʻano o Carbide PVC a me ka Ethylene PVC

    ʻO PVC kahi ʻano plastic i hoʻohana nui ʻia i nā mea kūkulu hale. No laila, ʻaʻole e hoʻololi ʻia no ka manawa lōʻihi i ka wā e hiki mai ana, a loaʻa iā ia nā manaʻo noi nui ma nā wahi i hoʻomohala ʻole ʻia i ka wā e hiki mai ana.

    E like me kā mākou e ʻike ai, ʻelua mau ala e hana ai i ka PVC, ʻo kekahi ke ʻano ethylene maʻamau maʻamau, a ʻo kekahi ʻo ke ʻano calcium carbide kūikawā ma Kina. ʻO nā kumu o ke ʻano ethylene ka nui o ka petroleum, aʻo nā kumu o ke ʻano calcium carbide ka nui o ka lanahu, ka limestone a me ka paʻakai. Hoʻopili nui ʻia kēia mau kumuwaiwai ma Kina. No ka manawa lōʻihi, aia ka PVC o ka calcium carbide method o Kina i kahi kūlana alakaʻi. Mai ka makahiki 2008 a hiki i ka 2014, ua hoʻonui ʻia ka mana hana PVC o Kina o ka calcium carbide method, akā ua lawe mai i nā pilikia palekana he nui.

    ʻO ka hoʻohana ʻana i ka mana o ka hana calcium carbide he nui loa, no laila e hoʻopiʻi kēia i kekahi mau pilikia i ka lako mana o Kina. Ma muli o ka hana ʻana o ka uila ma ka puhi ʻana i ka lanahu, pono ia e hoʻopau i ka nui o ka lanahu, no laila e hoʻohaumia ka lewa i ka puhi ʻana o ka lanahu. Eia naʻe, ua hoʻololi ʻo Kina i nā kulekele i nā makahiki. Ke hoʻomaikaʻi mau nei ʻo Kina i kāna kaulahao ʻoihana. I kēia manawa hiki iā mākou ke ʻike ua lawe mai ʻo Kina i ka nui o ka aila, a ua paipai ʻia nā ʻoihana kūloko e lawe mai i ka aila e hoʻomaʻemaʻe i nā huahana o lalo. No laila, i nā makahiki i hala iho nei, ua hoʻohui ʻia kekahi mau mea hana hana ethylene hou ma Kina, a ʻo ka mana hana PVC hou a pau ma Kina i nā makahiki i hala iho nei ʻo ia ka mana hana o ka hana ethylene. ʻO ka mana hana o ke ʻano calcium carbide o Kina ua hoʻōki i ka ʻae hou. No laila, i ka wā e hiki mai ana, e hoʻomau ka nui o nā mea kanu ethylene ma Kina a e hoʻomau ka emi ʻana o ke kaʻina hana calcium carbide. I ka wā e hiki mai ana, e hoʻomau ka hoʻonui ʻana o ka nui o ka ethylene kaʻina o Kina, a lilo i poʻokela i ka honua o ka ethylene process PVC.
