Wahi a nā helu helu, ʻoi aku ka nui o ka hana ʻana o ka waikawa acrylic ma 2 miliona i ka makahiki 2021, a ʻoi aku ka nui o ka hana ʻana o ka waikawa acrylic ma mua o 40 miliona mau. Hoʻohana ke kaulahao ʻoihana acrylate i nā esters acrylic e hana i nā esters acrylic, a laila hana ʻia nā esters acrylic ma o nā waiʻona pili. ʻO nā huahana i hōʻike ʻia o nā acrylates: butyl acrylate, isoctyl acrylate, methyl acrylate, ethyl acrylate a me ka acrylic acid resin absorbency kiʻekiʻe. Ma waena o lākou, nui ka nui o ka butyl acrylate, me ka hana ʻana o ka butyl acrylate ma mua o 1.7 miliona tons ma 2021. ʻO ka lua ʻo SAP, me ka hana ʻoi aku ma mua o 1.4 miliona tons ma 2021. ʻO ke kolu ʻo ka isooctyl acrylate, me kahi hana. ʻoi aku ma mua o 340,000 tons i 2021. ka hana ʻana o ka methyl acrylate a me ka ethyl ʻO ka acrylate he 78,000 tons a me 56,000 tons i ka makahiki 2021.

No nā noi ma ke kaulahao ʻoihana, hana nui ka waikawa acrylic i nā esters acrylic, a hiki ke hana ʻia ka butyl acrylate e like me nā mea hoʻopili. Hoʻohana ʻia ʻo Methyl acrylate i ka ʻoihana uhi, adhesives, textile emulsions, etc. Hoʻohana ʻia ʻo Isooctyl acrylate e like me ka monomer adhesive pressure-sensitive, coating adhesive, etc. Hoʻohana nui ʻia ʻo SAP ma ke ʻano he resin absorbent, e like me nā diapers.

E like me nā huahana pili i loko o ke kaulahao ʻoihana acrylate i nā makahiki ʻelua i hala iho nei, ka palena nui (kūʻai kūʻai / kumu kūʻai kūʻai) hoʻohālikelike, hiki ke loaʻa nā hopena aʻe.

1. i loko o ke kaulahao ʻoihana acrylate ma Kina, ʻoi aku ka kiʻekiʻe o ka loaʻa kālā ma ka upstream raw material end, me ka naphtha a me ka propylene he kiʻekiʻe nā palena waiwai. ʻO ka 2021 naphtha profit margin ma kahi o 56%, propylene profit margin ma kahi o 38%, a he 41% ka uku waiwai acrylic.

2. Ma waena o nā huahana acrylate, ʻo ka palena waiwai o ka methyl acrylate ka mea kiʻekiʻe loa. ʻO ka palena waiwai o ka methyl acrylate hiki i kahi o 52% i 2021, a ukali ʻia e ka ethyl acrylate me ka loaʻa kālā ma kahi o 30%. ʻO ka palena waiwai o ka butyl acrylate ma kahi o 9% wale nō, ʻo ka isooctyl acrylate i ka poho, a ʻo ka loaʻa kālā o SAP ma kahi o 11%.

3. Ma waena o nā mea hana acrylate, ʻoi aku ka nui o ka 93% i hoʻolako ʻia me nā mea kanu waika acrylic upstream, aʻo kekahi i lako me nā mea kanu acrylic acid, ʻo ka hapa nui o ia mau mea i hoʻopaʻa ʻia i nā ʻoihana nui. Mai ka hāʻawi kālā ʻana i kēia manawa o ke kaulahao ʻoihana acrylate hiki ke ʻike ʻia, hiki i nā mea hana acrylate i hoʻolako ʻia me ka waikawa acrylic hiki ke hōʻoia pono i ka nui o ka loaʻa kālā o ke kaulahao ʻoihana acrylate, ʻoiai ʻo nā mea hana acrylate me ka ʻole o ka waikawa acrylic i lako ʻia me ka waikawa acrylic ʻoi aku ka waiwai.

4, ma waena o nā mea hana acrylate, ua mālama ka palena waiwai o ka butyl acrylate i kahi ʻano paʻa i nā makahiki ʻelua i hala iho nei, me ka loaʻa kālā o 9% -10%. Eia nō naʻe, ma muli o ka hoʻololi ʻana o ka mākeke, ʻoi aku ka nui o nā palena waiwai o nā mea hana ester acrylic kūikawā. Hōʻike kēia i ka paʻa o ka loaʻa kālā o nā huahana nui, ʻoiai ʻoi aku ka maʻalahi o nā huahana liʻiliʻi i ka hopena o nā kumuwaiwai i lawe ʻia mai a me ke kaulike ʻole o ka hoʻolako ʻana i ka mākeke.

5, mai ke kaulahao ʻoihana acrylate hiki ke ʻike ʻia, hoʻomohala nā ʻoihana i ke kaulahao ʻoihana acrylate, kuhikuhi hana nui no ka butyl acrylate, aʻo ka acrylate kūikawā a me ka SAP i hana ʻia i ke ʻano kākoʻo o butyl acrylate, hiki ke hoʻomaikaʻi i ke kūʻē o ka mākeke. , akā, he ʻano hana kūpono hoʻi.

No ka wā e hiki mai ana, loaʻa i ka methyl acrylate, ethyl acrylate a me isoctyl acrylate kā lākou iho noi i lalo i ke kaulahao ʻoihana acrylate, a ʻo ka hoʻohana ʻana i lalo e hōʻike ana i ka ulu maikaʻi. Mai ka mākeke hoʻolako a me ka pae koi, ʻo ka methyl acrylate a me ka ethyl acrylate ka pilikia nui o ka hoʻolako ʻana a he awelika ka manaʻo e hiki mai ana. I kēia manawa, loaʻa i ka butyl acrylate, isooctyl acrylate a me SAP kekahi lumi no ka hoʻomohala ʻana a ʻo ia hoʻi nā huahana me kekahi mau waiwai i nā huahana acrylate i ka wā e hiki mai ana.

No ka hopena o ka ʻakika acrylic, propylene a me naphtha, nona ka ʻikepili maka e hoʻonui mālie ʻia, ʻoi aku ka kiʻekiʻe o ka waiwai o ka naphtha a me propylene ma mua o ka waika acrylic. No laila, inā hoʻomohala nā ʻoihana i ke kaulahao ʻoihana acrylate, pono lākou e noʻonoʻo nui i ka hoʻohui ʻana o ke kaulahao ʻoihana a hilinaʻi i nā pono hoʻomohala o ke kaulahao ʻoihana, e loaʻa ana ka mākeke.
