I kēia mau lā, ua wehe ka mākeke kemika i kahi ala "dragon and tiger" o ka piʻi ʻana, ke kaulahao ʻoihana resin, ke kaulahao ʻoihana emulsion a me nā kumu kūʻai kemika ʻē aʻe.
kaulahao oihana resin
ʻO Anhui Kepong resin, DIC, Kuraray a me nā ʻoihana kemika ʻē aʻe a me nā ʻāina ʻē aʻe i hoʻolaha i ka piʻi ʻana o ke kumukūʻai no nā huahana resin, polyester resin a me ka epoxy resin ʻoihana kaulahao o nā kumu waiwai i hoʻonui ʻia nā kumukūʻai, ʻo ka piʻi kiʻekiʻe loa o 7,866 yuan / ton.

ʻO ka resin polyester: hāʻawi i loko 13,800 yuan / ton, piʻi 2,800 yuan / ton i hoʻohālikelike ʻia me ka hoʻomaka o ka makahiki, a i ʻole 25.45%; Hāʻawi waho 14,800 yuan / ton, piʻi 1,300 yuan / ton i hoʻohālikelike ʻia me ka hoʻomaka o ka makahiki, a i ʻole 9.63%.

kaulahao ʻoihana emulsion

ʻO Badrich, Hengshui Xinguang Mea Hou, Guangdong Henghe Yongsheng Group a me nā alakaʻi emulsion ʻē aʻe i hoʻouna pinepine i nā leka e haʻi ana i ka piʻi ʻana o ke kumukūʻai huahana, ka papa benzene propylene, ka papa elastic wai, ka papa propylene maʻemaʻe kiʻekiʻe, ka papa pena pōhaku maoli a me nā huahana ʻē aʻe i piʻi maʻamau 600-1100 yuan / tona. ʻO nā mea waiwai emulsion e like me styrene, acrylic acid, methacrylic acid a me nā mea ʻē aʻe he nui e piʻi aʻe, ʻo ka piʻi kiʻekiʻe loa o 3,800 yuan / ton.

Styrene: ʻōlelo ʻia ma RMB 8960/ton, piʻi RMB 560/ton a i ʻole 6.67% mai ka hoʻomaka ʻana o ka makahiki.

Butyl acrylate: ʻōlelo ʻia ma 17,500 yuan/ton, piʻi 3,800 yuan/ton mai ka hoʻomaka ʻana o ka makahiki, he piʻi o 27.74%.

Methyl acrylate: ʻōlelo ʻia ma 18,700 yuan / ton, piʻi i 1,400 yuan / ton mai ka hoʻomaka ʻana o ka makahiki, he piʻi o 8.09%.

Acrylic acid: helu ʻia ma 16,033.33 yuan / ton, piʻi 2,833.33 yuan / ton mai ka hoʻomaka ʻana o ka makahiki, he piʻi o 21.46%.

Methacrylic acid: i helu ʻia ma 16,300 yuan / ton, piʻi 2,600 yuan / ton mai ka hoʻomaka ʻana o ka makahiki, a i ʻole 18.98%.

ʻO nā huahana o ke kaulahao ʻoihana kemika maʻamau, me ke kumukūʻai o nā huahana petroleum ma ke kumu hopena e hoʻokuʻu ʻia i luna, e alakaʻi ʻia kēia mau huahana i hoʻokahi pae, e hoʻonui ana i nā kumukūʻai o nā emulsions, resins a me nā huahana ʻē aʻe.

I ka manawa like, ma muli o ka paʻa ʻana o ke kaulahao hoʻolako, paʻakikī ka loaʻa ʻana o kahi pahu, ka nele o ke kumu, ka nele o nā keʻena a me ka nele o ka hana a me nā kumu hana ʻē aʻe, i hui pū ʻia me ka piʻi nui ʻana o nā kumukūʻai kūʻai honua, ʻoi aku ka nui. Ua piʻi aʻe ka pilikia o nā hui kemika, piʻi nui nā kumukūʻai hana, ʻo ka emi ʻana o ka hilinaʻi hoʻopukapuka, ʻaʻole i hoʻihoʻi maikaʻi ʻia ka noi no ke kūʻai ʻana, a ʻo ke kumukūʻai kiʻekiʻe o nā kemika ʻo ia wale nō ka "manaʻo manaʻo" huki.
