ʻO TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, helu CAS 91-97-4, he mea hoʻohui honua no ka hoʻomaikaʻi ʻana i nā waiwai mechanical a me nā kemika ma nā elastomers urethane. Loaʻa i nā apo benzene ʻelua i loko o ka molekole TODI kahi ʻano symmetrical. Ma muli o ke keakea steric o ka hui o-methyl, ʻoi aku ka haʻahaʻa o ka hana hopena ma mua o TDI a me MDI.

Ke hoʻohālikelike ʻia me nā elastomers polyurethane i hoʻokumu ʻia ma NDI, nā elastomers i hoʻokumu ʻia ma TODI, nā polyols oligomer a me MOCA he mau waiwai kino like, e like me ke kūpaʻa wela maikaʻi loa, ke kūpaʻa hydrolysis a me nā waiwai mechanical. Ke hoʻohālikelike ʻia me nā rubbers, plastics a me nā metala, ʻoi aku ka nui o nā pono o nā elastomers i hoʻokumu ʻia ma TODI, he paʻa lākou, kūpaʻa wela a me ke kūpaʻa hydrolysis. Hāʻawi nā elastomers i hoʻokumu ʻia ma TODI i nā waiwai mechanical maikaʻi loa e hoʻopili ʻia ma ka hana ma lalo o nā kūlana ʻino a/a i ʻole ke kaiapuni. Eia kekahi, ma muli o kona ola pot lōʻihi, ʻoi aku ka maʻalahi o ka lawelawe ʻana i ka prepolymer i hoʻokumu ʻia ma TODI i ka hoʻohālikelike ʻana me nā huahana NDI.

Noi

Me kona mau waiwai mechanical a me kemika kupaianaha, hoʻohana nui ʻia nā elastomers TODI ma nā ʻano like ʻole. ʻO ka mea mua, nā ʻāpana sila, e like me ke sila ʻaila, ke apo piston, nā sila wai a pēlā aku. A laila, ʻo nā ʻāpana kaʻa kekahi noi nui o TODI, me nā hoʻonui bumper, nā mea hoʻokuʻu haʻalulu, nā grills a me nā mea ʻē aʻe. Eia kekahi, hoʻohana ʻoihana kiʻekiʻe, ʻo ia hoʻi nā kāʻei, nā ʻōwili, nā casters. Eia kekahi, he mea uhi koʻikoʻi ʻo TODI i ke kahua uila a ma ke ʻano he mau ʻōpū hana i nā lako lapaʻau.

Hoʻopili a me ka mālama ʻana

Hoʻopili ʻana: 50kgs/pahu hao.

Ka mālama ʻana a me ka halihali ʻana: He maʻalahi ka TODI i ka makū. Hoʻopili ka wai me nā diisocyanates āpau e hana i nā urea derivatives insoluble. Pono e mālama ʻia ʻo TODI i loko o nā pahu i hoʻopaʻa paʻa ʻia i nā kūlana anuanu a maloʻo.

MAI hoʻokomo i ka TODI me ka meaʻai a pale i ka hōʻike ʻana i kahi mahana ma luna o 30℃. Ma hope o ka hoʻohana ʻana, pono e sila koke ʻia ke poʻi inā pilikia. Ma lalo o nā kūlana mālama kūpono, kūpono ka TODI no ʻeono mahina ma ka liʻiliʻi mai ka lā i hāʻawi ʻia ai.
