ʻO Bis(2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5ʻO ia ka monomeric carbodiimide, kahi ʻano ʻokoʻa o ka mea anti-hydrolysis nona nā ʻano o ka maʻemaʻe kiʻekiʻe, ke kala māmā, ʻaʻohe ʻala a me ka hana kiʻekiʻe. Hoʻohana nui ʻia ʻo Bis(2,6-diisopropylphenyl) carbodiimide i nā mea e like me ka polyester polyol, nylon, nā plastics ʻenekinia e loaʻa ana ka hui ester, nā elastomers polyurethane, nā mea hoʻopili, nā ʻōnaehana uhi, a me ka ʻaila lubricating. Hiki i ka Bis(2,6-diisopropylphenyl) carbodiimide ke kāohi pono i ka hydrolysis o ia mau mea a hoʻopaʻa i nā waiwai mechanical mua. I ka manawa like,bhiki iā is(2,6-diisopropylphenyl) carbodiimide ke ālai i nā hoʻopau carboxyl ikaika o nā mea polyester. Hoʻoponopono i nā mea polyester a me polyurethane i hōʻino ʻia,bhiki i ka is(2,6-diisopropylphenyl) carbodiimide ke hoʻolōʻihi i ke ola lawelawe o nā huahana polymer ma lalo o nā kūlana hana koʻikoʻi e like me ke kiʻekiʻe o ka mahana a me ka haʻahaʻa.

Ma ke kahua o ka ʻepekema mea, bis(2,6-diisopropylphenyl)carbodiimide, ma ke ʻano he monomeric carbodiimide anti-hydrolysis stabilizer, ua lilo ia i mea nui o ka ʻoihana no kāna hana maikaʻi loa a me nā manaʻolana noi ākea.

ʻO ka mea mua,Hoʻohana nui ʻia ʻo bis(2,6-diisopropylphenyl) carbodiimide i nā elastomers polyurethane (e like me TPU, CPU), nā mea hoʻopili, nā hopena sole a me nā elastomers Microporous, a pēlā aku. Ma kēia mau kahua, ma ka hoʻohui ʻana i ka 0.3-2.0% bis(2,6-diisopropylphenyl) carbodiimide, hiki ke hoʻomaikaʻi nui ʻia ke ola lawelawe o ka huahana, e hoʻolōʻihi ana iā ia a hiki i 1 a 3 mau manawa.

ʻO ka lua, i ka wā o ke kaʻina hana hoʻololi o nā mea polyester e like me PET/PBT, hiki i ka hoʻohui ʻana i ka bis(2,6-diisopropylphenyl) carbodiimide ke hōʻemi i ka waiwai waikawa o ka polyester. Hiki ke hoʻokō ʻia nā hoʻomaikaʻi koʻikoʻi i ka maikaʻi o nā mea me nā nui hoʻohui haʻahaʻa, e hoʻolōʻihi ana i ke kūpaʻa lōʻihi o ka mea.

Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he mea anti-hydrolysis, hiki ke hoʻohana ʻia ka bis(2,6-diisopropylphenyl)carbodiimide ma ke ʻano he mea kōkua hana e hana me nā waikawa carboxylic i hana ʻia i ka wā o ke kaʻina hana extrusion. ka hopena, e pale ana i ka hōʻemi ʻana o ke kaumaha molekala, e hoʻonāwaliwali ana i ka hōʻino ʻana i ka polymer i ka wā o ke kaʻina hana, e maʻalahi ai ka hana a hoʻomaikaʻi i ka palekana hana i hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe.

Eia kekahi, no ka PLA palakiko biodegradable a aloha i ke kaiapuni, ʻo ke kūpaʻa hydrolysis maikaʻi ʻole ka mea nui e kaupalena ana i kāna noi ākea. Hoʻohaumia maʻalahi ʻia ka PLA i nā wahi humid, e hoʻopilikia ana i kāna hana a me ke ola. Eia nō naʻe, ma ka hoʻohui ʻana i ka 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide i ka PLA, hiki ke hoʻomaikaʻi nui ʻia kona kūpaʻa wai e 3-7 mau manawa, e hoʻonui pono ana i katnā kahua noi o PLA.

I ka huinamʻO ary, bis(2,6-diisopropylphenyl)carbodiimide, ma ke ʻano he mea hoʻopaʻa anti-hydrolysis hana kiʻekiʻe, ua hōʻike i ka hiki ke hoʻohana ākea a me ka hiki ke hana ma ke kahua o ka ʻepekema mea. waiwai.ItʻO nā waiwai kino a me nā kemika maikaʻi loa o ia mea, ka laulā o nā noi, a me nā hopena i kuhikuhi ʻia no nā mea kikoʻī (e like me PLA) e hoʻolilo iā bis(2,6-diisopropylphenyl)carbodiimide i alakaʻi i ka hoʻopaʻa ʻana i nā mea. Me ka holomua mau o ka ʻepekema mea a me ka hoʻonui ʻana i ka ʻike o ka palekana o ke kaiapuni, manaʻo ʻia e hoʻolaha ʻia a hoʻohana ʻia ka bis(2,6-diisopropylphenyl)carbodiimide a me kāna mau huahana like ma nā kahua hou aʻe.
