Ke Au o PVC, Ke Au o Carbide PVC a me Ethylene PVC

He ʻano palakika ka PVC i hoʻohana nui ʻia i nā mea hana hale. No laila, ʻaʻole ia e pani ʻia no ka manawa lōʻihi i ka wā e hiki mai ana, a he mau manaʻolana nui kona no ka hoʻohana ʻana ma nā wahi i hoʻomohala ʻole ʻia i ka wā e hiki mai ana.

E like me kā kākou e ʻike nei, ʻelua ala e hana ai i ka PVC, ʻo kekahi ke ʻano ethylene maʻamau o ka honua, a ʻo kekahi ke ʻano calcium carbide kū hoʻokahi ma Kina. ʻO nā kumu o ke ʻano ethylene ka petroleum nui, ʻoiai ʻo nā kumu o ke ʻano calcium carbide ka lanahu, ka limestone a me ka paʻakai. Hoʻopili nui ʻia kēia mau kumuwaiwai ma Kina. No ka manawa lōʻihi, ua noho ke ʻano calcium carbide PVC o Kina i kahi kūlana alakaʻi loa. ʻOi loa aku mai 2008 a 2014, ua piʻi aʻe ka hiki ke hana PVC o Kina i ke ʻano calcium carbide, akā ua lawe mai hoʻi i nā pilikia palekana kaiapuni he nui.

He nui loa ka hoʻohana ʻana i ka mana o ka hana ʻana o ka calcium carbide, no laila e hoʻopilikia kēia i ka lako mana o Kina. No ka mea, ua hana ʻia ka uila e ka puhi ʻana i ka lanahu, pono ia e hoʻopau i ka nui o ka lanahu, no laila e haumia ka lewa i ka puhi ʻana o ka lanahu. Eia naʻe, ua hana ʻo Kina i kekahi mau hoʻololi 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 ʻaila, a ua paipai ʻia nā ʻoihana kūloko e lawe mai i ka ʻaila e hoʻomaʻemaʻe i nā huahana ma hope. No laila, i nā makahiki i hala iho nei, ua hoʻohui ʻia kekahi mau mea hana hana ethylene hou ma Kina, a ʻo nā mea hana PVC hou a pau ma Kina i nā makahiki i hala iho nei ʻo ia ka hiki ke hana o ke kaʻina hana ethylene. Ua hoʻōki ka hiki ke hana o ke ʻano hana calcium carbide o Kina i ka ʻae hou ʻana. No laila, i ka wā e hiki mai ana, e hoʻomau ka nui o nā hale hana 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 nui o ka hoʻokuʻu aku o Kina i ke kaʻina hana ethylene, a e lilo mālie i mea hoʻokuʻu aku i ka honua o ke kaʻina hana ethylene PVC.
