4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, helu CAS 19900-72-2, ua hoʻohana ʻia ma ke ʻano he mea hoʻonui kaulahao no nā elastomers polyurethane a ma ke ʻano he mea hoʻōla no ka resin epoxy e hoʻomaikaʻi ai i nā waiwai mechanical a me ka ikaika. o nā huahana. Hiki ke hoʻohana ʻia ʻo MED ma ke ʻano he hui alakaʻi no nā polyimides a ma ke ʻano he intermediation no ka synthesis organik.

He kūpono no ka hoʻolei ʻana i ka polyurethane (CPU), thermoplastic polyurethane (TPU), RIM elastomers a me ka pulupulu polyurea ma ke kahua polyurethane. Hoʻopili pū ʻia ʻo MED no ka hoʻoili ʻana, prepreg a me nā kemika anticorrosive coatings i ka māla epoxy resin. Hoʻohana ʻia ʻo MED i ka synthesis o nā prepolymers, me ka polyether a me ka polyester.

ʻO MED kahi hopena kūpono no nā huahana i hoʻopau ʻia e koi ana i ka kala māmā a me ka anti-aging. Hiki ke hoʻohana ʻia ʻo MED me nā mea hoʻōla ʻano amine ʻē aʻe (compound) e hoʻokō i nā waiwai kino maikaʻi aʻe.

ʻO MED a me MOCA ʻelua mau mea hoʻōla ʻano amine. Eia nō naʻe, ʻoluʻolu ka MED a me ka liʻiliʻi o ka haumia i ka hoʻohālikelike ʻana me MOCA. Hiki i ka MED ke pani i ka MBOEA a me ka HQEE ma nā huahana PU, ʻaʻohe CPU (casting polyurethane) a i ʻole TPU (thermoplastic polyurethane). E like me MOCA, MED-type elastomers hiʻohiʻona me ka wela-kū'ē maikaʻi e koi ana i ka hana ma luna o 120 ℃

Palapala noi

ʻO MED/MMEA kahi mea hoʻonui kaulahao diamine ʻala a me ka mea ho'ōla. Ma muli o nā hoʻoponopono koʻikoʻi e pili ana i ka hoʻohana ʻana iā MOCA, ʻo ka MED eco-friendly, non-polluted kahi koho kūpono ʻē aʻe e pili ana i nā noi like ʻole. ʻO nā polyurethanes MED-base he versatility a me ke kūʻokoʻa hoʻolālā, me nā waiwai ikaika kiʻekiʻe aʻo ka mālama ʻana i kona elasticity. ʻO nā huahana hoʻopau MED-type he mau lōʻihi a kūpaʻa e hiki ai iā lākou ke kūpono i nā noi koi, e like me nā bumper pads, casters, rollers, forklift tires, machine parts a pēlā aku. Eia kekahi, hiki ke hoʻohana ʻia ʻo MED ma ke ʻano he alahaka ma ka semi-conductor a ma ke ʻano he mea hoʻōla ma ka epoxy a me ka polyurea.

Hoʻopaʻa a mālama

No 4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA a puni ka honua. ʻO kā mākou hana makahiki he 400 metric tons.

Hoʻopili: 180kgs / ʻeke; 300kgs / ʻeke, 18kgs / ʻeke

Ka mālama ʻana a me ka lawe ʻana: E kūʻai i kahi wahi me ka makani. No ka mea he hygroscopicity liʻiliʻi kēia huahana, e ʻoluʻolu e pale i ka pili ʻana me ka wai a pale i ka lā. E hoʻopaʻa paʻa i ka pahu ma hope o ka hoʻohana ʻana. I kēia manawa, ʻaʻole hiki ke mālama ʻia me nā oxidants.
