I kēia manawa, ʻaʻole lawa ka hahai ʻana o ka mākeke noiʻi, e hopena i kahi lewa noiʻi māmā.ʻO ka manaʻo nui o ka poʻe paʻa ma ke kūkākūkā hoʻokahi, akā ʻike ʻia ka nui o ke kālepa ʻana he haʻahaʻa haʻahaʻa, a ua hōʻike pū ka manaʻo i kahi ʻano nāwaliwali a hoʻomau i lalo.
Ma Kina Hikina, ke hoʻomau nei ke kālepa a me ka hoʻopukapuka ʻana o ka mākeke resin epoxy wai i kahi ʻano iho.Eia kekahi, he haʻahaʻa haʻahaʻa ka lewa o ka mākeke maka ʻelua, kahi mea paʻakikī ke kākoʻo i ka noʻonoʻo o ka ʻoihana resin.Ma waena o lākou, hoʻomau nā kauoha hou e hāʻawi i nā uku, a ke hōʻike pū nei ke kikowaena kālepa o ka mākeke i kahi ʻano iho.ʻO ke kumukūʻai kuhikuhi i kūkākūkā ʻia ma waena o 13000-13600 yuan / ton, me ka nānā ʻana i ka waena a i ka hopena haʻahaʻa.
Ma Kina Hema, ua hōʻike pū ka mākeke wai epoxy resin i kahi ʻano haʻahaʻa haʻahaʻa.Ua nāwaliwali ka hana kūʻai kinoea lalo, a ua hoʻomaka kekahi mau hale hana e hōʻemi i kā lākou mau ʻōlelo no ka huki ʻana i nā kauoha.He haʻahaʻa nō hoʻi ke kumu kūʻai ʻāpana maoli, me ke kumu kūʻai i kūkākūkā ʻia mai ka 13200 a i ka 13800 yuan/ton, me ka nānā ʻana i ka waena a i ka hopena haʻahaʻa.
Nawaliwali nā kumukūʻai o bisphenol A a me Epichlorohydrin, a makaʻala nā mea kūʻai ma ka mākeke.
Ma ka makeke bisphenol A, ʻike ʻia ke kālepa ʻana me ka mālie, me ka liʻiliʻi o ka hoʻololi ʻana i ka noi o lalo, a ʻo nā hale hana sporadic wale nō e hana i nā nīnau noiʻi.ʻAʻole nui nā manawa i hāʻawi manawaleʻa ai kekahi mau mea hana bisphenol A, a ʻo ke kumu kūʻai i kūkākūkā ʻia ma kahi o 8800-8900 yuan/ton, me ka haʻahaʻa haʻahaʻa.
He maʻalahi ke kūkākūkā mākeke o Epichlorohydrin, a ua makemake ka mea kūʻai aku e hāʻawi i 7700 yuan / ton, ʻoiai ma Shandong, hāʻawi kekahi mau mea hana i ke kumu kūʻai haʻahaʻa o 7300 yuan / ton.
I ka hōʻuluʻulu ʻana, ma muli o ka maikaʻi ʻole o ka hoʻouna ʻana i lalo a me ke kālepa ʻana, e kokoke mai ana ka lā ʻapōpō i ka hopena pule, a ua manaʻo ʻia e mālama ka mākeke i kahi hoʻololi haʻahaʻa a nāwaliwali nā kumukūʻai.
