Kumukūʻai maikaʻi o ka mea hana DINP Papa ʻoihana CAS：28553-12-0

ʻO Diisononyl phthalate (DINP)：He wai ʻaila moakaka kēia huahana me kahi ʻala iki. He plasticizer nui ia me nā waiwai maikaʻi loa. Hiki ke hoʻoheheʻe ʻia kēia huahana i loko o ka PVC, a ʻaʻole e hoʻokahe ʻia ʻoiai inā hoʻohana ʻia i ka nui. ʻOi aku ka maikaʻi o ka volatilization, ka neʻe ʻana a me ka non-toxicity ma mua o DOP (dioctyl phthalate), hiki ke hāʻawi i ka huahana i ke kūpaʻa kukui maikaʻi, ke kūpaʻa wela, ke kūpaʻa ʻelemakule a me nā waiwai insulation uila, a ʻoi aku ka maikaʻi o ka hana piha ma mua o DOP. No ka mea, he kūpaʻa wai maikaʻi nā huahana i hana ʻia e kēia huahana a me ke kūpaʻa unuhi, haʻahaʻa ka toxicity, kūpaʻa ʻelemakule, hana insulation uila maikaʻi loa, no laila ua hoʻohana nui ʻia i loko o nā kiʻiʻoniʻoni pāʻani, uea, a me ke kaula.

Ke hoʻohālikelike ʻia me DOP, ʻoi aku ka nui a me ka lōʻihi o ke kaumaha molekala, no laila he ʻoi aku ka maikaʻi o ka hana ʻelemakule, ke kūʻē i ka neʻe ʻana, ka hana anticairy, a me ke kūʻē ʻana i ka mahana kiʻekiʻe. Pēlā nō, ma lalo o nā kūlana like, ʻoi aku ka ʻino o ka hopena plasticization o DINP ma mua o DOP. Manaʻo nui ʻia he ʻoi aku ka maikaʻi o ka DINP ma mua o DOP.

ʻOi aku ka maikaʻi o DINP i ka hoʻomaikaʻi ʻana i nā pono extrusion. Ma lalo o nā kūlana hana extrusion maʻamau, hiki iā DINP ke hōʻemi i ka viscosity heheʻe o ka hui ʻana ma mua o DOP, kahi e kōkua ai i ka hōʻemi ʻana i ke kaomi o ke kumu hoʻohālike awa, hōʻemi i ka ʻaʻahu mechanical a hoʻonui paha i ka huahana (a hiki i ka 21%). ʻAʻohe pono e hoʻololi i ke ʻano huahana a me ke kaʻina hana, ʻaʻohe hoʻopukapuka kālā hou aʻe, ʻaʻohe hoʻohana ikehu hou aʻe, a me ka mālama ʻana i ka maikaʻi o ka huahana.

He wai ʻaila ka DINP maʻamau, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai. Lawe pinepine ʻia e nā kaʻa tanker, nā bākeke hao liʻiliʻi a i ʻole nā ​​​​barela plastik kūikawā.

ʻO kekahi o nā mea maka nui o DINP -INA (INA), i kēia manawa he kakaikahi wale nō nā ʻoihana ma ka honua e hiki ke hana, e like me Exxon Mobil o ʻAmelika Hui Pū ʻIa, ka ʻoihana lanakila o Kelemania, ka Concord Company o Iapana, a me ka ʻoihana ʻAsia Hema ma Taiwan. I kēia manawa, ʻaʻohe ʻoihana kūloko e hana ana i ka INA. Pono nā mea hana a pau e hana ana i ka DINP ma Kina e hele mai mai nā mea i lawe ʻia mai.
