ʻO TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, helu CAS 91-97-4, he mea hoʻohui āpau no ka hoʻomaikaʻi ʻana i nā waiwai mechanical a me nā kemika ma nā elastomers urethane. ʻO nā apo benzene ʻelua i loko o ka mole TODI he ʻano hoʻohālikelike. Ma muli o ka pale steric o ka hui o-methyl, ʻoi aku ka haʻahaʻa o ka hana pane ma mua o ka TDI a me MDI.

Ke hoʻohālikelike nei i nā elastomers polyurethane NDI, nā elastomers i hoʻokumu ʻia ma TODI, nā oligomer polyols a me MOCA loaʻa nā ʻano 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 maikaʻi o nā elastomers e pili ana i TODI, ʻoi aku ka lōʻihi, ke kūpaʻa wela a me ke kūpaʻa hydrolysis. Hāʻawi nā elastomers i hoʻokumu ʻia i TODI i nā waiwai mechanical maikaʻi e hoʻohana ʻia ma ka hana ʻana ma lalo o nā kūlana paʻakikī a / a i ʻole ka honua. Eia kekahi, ma muli o kona ola ʻana i ka ipu hao, ʻoi aku ka maʻalahi o ka prepolymer e pili ana i ka TODI i ka hoʻohālikelike ʻana i nā huahana NDI.

Palapala noi

Me kona mau waiwai mechanical a me kemika, ua hoʻohana nui ʻia nā elastomers i hoʻokumu ʻia TODI ma nā ʻano āpau. ʻO ka mea mua, hoʻopaʻa i nā mea, e like me ka hoʻopaʻa ʻana i ka aila, ke apo piston, nā sila wai a pēlā aku. A laila, ʻo nā ʻāpana kaʻa kekahi noi nui o TODI, me ka hoʻonui ʻana i ka bumper, nā mea haʻalulu, nā grills a me nā mea ʻē aʻe. Eia kekahi, ʻo TODI kahi mea hoʻopili koʻikoʻi ma ke kahua uila a ma ke ʻano he mea hana i nā mea lapaʻau.

Hoʻopaʻa a mālama

Hoʻopili: 50kgs / pahu hao.

Ka mālama ʻana a me ka lawe ʻana: He maʻalahi ka TODI i ka makū. Hoʻopili ka wai me nā diisocyanates a pau e hana i nā derivatives urea hiki ʻole ke hoʻoheheʻe. Pono e mālama ʻia ʻo TODI i loko o nā pahu i hoʻopaʻa paʻa ʻia i nā kūlana maloʻo a maloʻo.

Mai hoʻokomo i ka TODI me ka meaʻai a pale i ka hōʻike ʻana i kahi kaiapuni ma luna o 30 ℃. Ma hope o ka hoʻohana ʻana, pono e hoʻopaʻa ʻia ka poʻi i ka wā o ka dysfunction. Ma lalo o nā kūlana mālama kūpono, pono ʻo TODI no ʻeono mahina ma ka liʻiliʻi me ka hopena mai ka lā i lawe ʻia ai.
