ʻO ke kaulike ʻole o ka lako-koi i hui pū ʻia me ka hopena o ka wā ma waho, aia ka mākeke PVC i ka oscillation nāwaliwali a me ka wili ʻana ma ka lalo.

I kēia manawa, aia ka mākeke PVC i loko o kahi ʻano oscillating nāwaliwali, ma muli o ke kaulike ʻole o ka lako-koi i hoʻoholo ʻole ʻia.

Kūlana Hoʻolako Koʻikoʻi a me ka Waihona

• Ua ʻoi aku ka wikiwiki o ka hoʻomaka hou ʻana o ka hana ʻoihana ma mua o ka hopena o ka mālama ʻana, me ka piʻi ʻana o ka nui o ka hana o ka pauka PVC i 80.55%.
• Ke hoʻokuʻu nui ʻia nei ka mana hana hou i ka makahiki 2025, me 2.2 miliona tone i hoʻokomo mua ʻia i ka hana a me 500,000 tone i koe e hoʻokuʻu ʻia ma hope, e hopena ana i ka nele o ka lako.
• Ua piʻi aʻe ka waihona waiwai ma ka Hikina a me ka Hema o Kina i 544,100 tons, me ka lohi o ka hoʻoheheʻe ʻana i ka waihona. E hoʻomau ʻia nā pae waihona kiʻekiʻe i ka hapaha ʻehā.

Kumukūʻai a me ka Hana Kūʻai

• Ua nāwaliwali nā mākeke futures a me nā mākeke kiko i ka manawa like. ʻO ke kumukūʻai pani o ka ʻaelike PVC futures nui (V2601) he 4,611 yuan/ton.
• ʻO ke kumukūʻai kiko o ka calcium carbide-based type 5 PVC mai 4,510 a 4,640 yuan/ton ma Kina Hikina a me 4,620 a 4,670 yuan/ton ma Kina Hema, me ke kālepa lahilahi.
• Ke holo nei nā kumukūʻai o nā mea maka (calcium carbide a me ka caustic soda) ma nā pae haʻahaʻa, a nāwaliwali ke kākoʻo kumukūʻai no ke ʻano hana e pili ana i ka ethylene, e ʻūlū ana i nā palena waiwai o nā ʻoihana chlor-alkali.

Koi a me ke ʻano holoʻokoʻa

• Ua komo ke koi i ke kau hoʻomaha o ke kau. Ua hōʻemi ka hāʻule ʻana o ka mahana ma nā ʻāpana ʻākau i nā hana kūkulu, e alakaʻi ana i ka nāwaliwali o ke koi ma lalo no nā paipu PVC, nā ʻāpana a me nā huahana nui ʻē aʻe.
• Ke hoʻomau nei ke kaomi ʻekolu mai nā palena o ka lako, ka nui o ka waihona a me ke koi ma waho o ke kau. Me ka ʻole o nā mea hoʻonāukiuki ikaika e like me nā kulekele macro maikaʻi i ka wā pōkole, e hoʻomau ka mākeke i kona oscillation nāwaliwali.
• Pono nā mea komo i loko o ke kaulahao ʻoihana e nānā pono i ka wikiwiki o ke kauoha ʻana i nā mana hou, nā loli o ka waihona a me nā loli kumukūʻai.
