I nā makahiki i hala iho nei, ua hoʻomau ka ʻoihana polyethylene o Kina i ka manawa ikaika o ka hoʻomohala ʻana, me ka ulu nui o ka hoʻopuka a me ka hoʻohana ʻana i alakaʻi i ka honua.I ka manawa like, ʻo Kina ka mea lawe nui loa i ka polyethylene ma ka honua.Eia nō naʻe, me ka wikiwiki o ka ulu ʻana o ka ʻoihana, ua puka mālie nā kūʻē ʻana, e like me ka overcapacity o nā huahana waena a me nā huahana haʻahaʻa, hoʻokūkū homogeneous koʻikoʻi, a me ka pilikia o ka nalowale o ka ʻāpana.No laila, ʻo ia ke alakaʻi holomua nui o ka ʻoihana e hāpai i ka hoʻomaikaʻi ʻana i ke ʻano o ka huahana o nā huahana polyethylene a ʻike i ka ʻoihana huahana, ʻokoʻa, kiʻekiʻe, ʻōmaʻomaʻo a me ka hana maʻamau.He mea koʻikoʻi ia no nā ʻoihana e hopu i ka manawa ma lalo o ka hoʻokūkū ikaika i ka ʻoihana e hiki mai ana.

I kēia manawa, hoʻohana nui ʻia ka polyethylene i nā māla 5 e hiki mai ana, ke kiʻiʻoniʻoni, ka hoʻoheheʻe ʻana, ka hollow a me ke kaha kiʻi, ka paipu.Me ka hoʻomohala ʻana o ka māla degradable, ua paʻa ka polyethylene e hopu i kahi māhele mākeke, aʻo nā mea ʻē aʻe UHMWPE, MLLDPE, EVA a me POE elastomers e hāʻawi i nā mea maikaʻi o nā huahana i loko o ʻelima mau māla, e like me ka diaphragm pākahi lithium kiʻekiʻe, photovoltaic packaging film. , mea ho'opili ki'i ki'i ki'i ki'i ki'i ki'i ki'i a me nā noi kahua moana.

I ka makahiki 2022, e hoʻonui ʻia ka nui o ka polyethylene o Kina i 29.81 miliona tons / makahiki, me ka awelika o ka ulu ʻana o ka makahiki he 12.32%, a e mālama ia i ka wikiwiki wikiwiki o 12% i nā makahiki ʻelima e hiki mai ana.No laila, ʻo ka hoʻomaikaʻi ʻana i ka hoʻolālā huahana ke ʻano o The Times.Hoʻokaʻawale ʻia nā ʻoihana hana polyethylene homeHDPE, LDPEa me FDPE ʻekolu ʻano o nā mea hana, ʻo nā mea hana ʻekolu ma luna nei he 44%, 16% a me 40% o ka nui o ka mana.I kēia manawa, me ka hoʻomohala wikiwiki ʻana o ka ʻoihana polyethylene o Kina, i mea e hoʻoponopono ai i ka kūʻē ʻana o ka "huahana haʻahaʻa haʻahaʻa a me ka nele o nā huahana kiʻekiʻe", e hoʻololi ke ʻano ʻoihana i ka ʻokoʻa a me ka hopena kiʻekiʻe.I mea e hopu ai i ka mākeke mea kūʻai aku i ka wā e hiki mai ana, ua kokoke mai ka ʻoihana huahana, ka ʻokoʻa a me ka pae kiʻekiʻe.

I kēia manawa, aia ʻekolu ʻano o nā huahana plastik kiʻekiʻe e hiki ke hana ʻia i loko o nā hale hana mua o ka ʻoihana, ʻo ia hoʻi MLLDPE (metallocene polyethylene), UHMWPE (ultra-high molecular weight polyethylene) a me EVA;Pono e hana ʻia ka POE elastomer a me nā huahana plastik degradable e kahi mea hana hou.Aia kēia mau ʻano huahana ʻelima i nā ʻano plastik kiʻekiʻe me nā kumukūʻai kiʻekiʻe, nā waiwai waiwai a me nā manaʻo ākea.Ke alakaʻi ʻia nei e ka pahuhopu koʻikoʻi o "kāpona pālua" a me nā kulekele hoʻomalu kaiapuni, ʻo Kina, ma ke ʻano he mea kūʻai nui, e hoʻohana pono i ka makani hikina o ke kulekele, me ka palena ʻole a me ka hoʻohiki ʻana i ka wā e hiki mai ana.
