Ingcaciso yeMveliso

I-TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, inombolo ye-CAS 91-97-4, iyongezwa yonke indawo yokuphucula iimpawu zomatshini kunye neekhemikhali kwi-urethane elastomers. Amakhonkco amabini ebenzene akwimolekyuli ye-TODI anesakhiwo esilingeneyo. Ngenxa yesithintelo se-steric seqela le-o-methyl, umsebenzi wokuphendula ungaphantsi kune-TDI kunye ne-MDI.

Ukuthelekisa i-NDI-based polyurethane elastomers, i-elastomers esekelwe kwi-TODI, i-oligomer polyols kunye ne-MOCA zinezakhiwo ezibonakalayo ezibonakalayo, ezifana nokuchasana nokushisa okukhulu, ukuxhathisa kwe-hydrolysis kunye neempawu zomatshini. Xa kuthelekiswa neerabha, iiplastiki kunye nesinyithi, i-elastomers esekelwe kwi-TODI ineenzuzo ezininzi ngakumbi, zihlala ziqinile, zixhathisa ubushushu kunye nokumelana ne-hydrolysis. I-elastomers ezisekelwe kwi-TODI zibonelela ngeepropati eziphezulu zoomatshini eziza kusetyenziswa ekusebenzeni phantsi kweemeko ezinzima kunye / okanye okusingqongileyo. Ngaphezu koko, ngenxa yobomi bayo obude bembiza, i-TODI-based prepolymer kulula ukuyiphatha xa kuthelekiswa neemveliso ezise-NDI.

Isicelo

Ngeempawu zayo ezibalaseleyo zoomatshini kunye neekhemikhali, ii-elastomers ezisekelwe kwi-TODI zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo. Okokuqala, izinto zokutywina, ezifana nokutywinwa kweoli, i-piston ring, izitywina zamanzi njalo njalo. Emva koko, iinxalenye zemoto zesinye isicelo esikhulu se-TODI, kubandakanywa izandiso ze-bumper, i-shock absorbers, i-grills kunye nokunye. Ngaphaya koko, i-TODI yiarhente ebalulekileyo yokwambathisa kwintsimi yombane nanjengamalungu okwenziwa kwezixhobo zonyango.

Ukupakisha kunye noGcino

Ukupakisha: 50kgs / igubu lentsimbi.

Ukugcinwa kunye nokuthuthwa: I-TODI ivakalelwa kukufuma. Amanzi adibana nazo zonke ii-disocyanates ukwenza izinto eziphuma kwi-urea ezinganyibilikiyo. I-TODI kufuneka igcinwe kwizikhongozeli ezitywinwe ngokuqinileyo kwiimeko ezipholileyo nezomileyo.

Sukuyifaka i-TODI kunye nokutya kwaye uphephe ukuveza kwindawo engaphezulu kwe-30℃. Emva kokusetyenziswa, isiciko kufuneka sivalwe ngokukhawuleza xa kukho ukungasebenzi. Phantsi kweemeko ezifanelekileyo zogcino, i-TODI isemthethweni kangangeenyanga ezintandathu ubuncinane ukususela kumhla eziswa ngawo.
