Ingcaciso yeMveliso

I-TODI / 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, inombolo ye-CAS 91-97-4, sisongezelelo esiqhelekileyo sokuphucula iipropati zoomatshini kunye neekhemikhali kwi-urethane elastomers. Iindandatho ezimbini zebenzene kwimolekyuli ye-TODI zinesakhiwo esilinganayo. Ngenxa yokuphazamiseka kwe-steric kweqela le-o-methyl, umsebenzi wokusabela uphantsi kunowe-TDI kunye ne-MDI.

Xa kuthelekiswa nee-elastomers ze-polyurethane ezisekwe kwi-NDI, ii-elastomers ezisekwe kwi-TODI, ii-polyol ze-oligomer kunye ne-MOCA zineempawu ezifanayo zomzimba, ezifana nokumelana nobushushu okugqwesileyo, ukumelana ne-hydrolysis kunye neempawu zoomatshini. Xa kuthelekiswa neerabha, iiplastiki kunye neentsimbi, ii-elastomers ezisekwe kwi-TODI zinezibonelelo ezininzi, zihlala ixesha elide, ukumelana nobushushu kunye nokumelana ne-hydrolysis. Ii-elastomers ezisekwe kwi-TODI zibonelela ngeempawu zoomatshini eziphezulu ezingasetyenziswa xa zisebenza phantsi kweemeko ezinzima kunye/okanye kwindawo engqongileyo. Ngaphezu koko, ngenxa yobomi bayo obude bembiza, i-prepolymer esekwe kwi-TODI kulula ukuyiphatha xa ithelekiswa neemveliso ezisekwe kwi-NDI.

Isicelo

Ngenxa yeempawu zayo ezibalaseleyo zoomatshini nezekhemikhali, ii-elastomers ezisekelwe kwi-TODI zisetyenziswa kakhulu kwiindawo ezahlukeneyo. Okokuqala, izinto zokuvala, ezifana nokuvala ioyile, iringi yepiston, izitywino zamanzi njalo njalo. Emva koko, iindawo zeemoto zezinye izinto ezisetyenziswa kakhulu kwi-TODI, kubandakanya ukwandiswa kwe-bumper, ii-shock absorbers, ii-grills njl. Ngaphandle koko, ukusetyenziswa okuphezulu kwimizi-mveliso, oko kukuthi, iibhanti, ii-rolls, ii-casters. Ngaphezu koko, i-TODI yiarhente ebalulekileyo yokugquma kwicandelo lombane kwaye njengezitho zokwenziwa kwizixhobo zonyango.

Ukupakisha kunye nokugcina

Ukupakisha: 50kgs/idrama yentsimbi.

Ukugcinwa kunye nokuthuthwa: I-TODI ayivani nokufuma. Amanzi asabela kunye nazo zonke ii-diisocyanates ukuze enze ii-urea derivatives ezinganyibilikiyo. I-TODI kufuneka igcinwe kwizikhongozeli ezivalwe ngokuqinileyo kwiimeko ezipholileyo nezomileyo.

Musa ukufaka i-TODI kunye nokutya kwaye uphephe ukuyibeka kwindawo engaphezulu kwama-30℃. Emva kokusebenzisa, isiciko kufuneka sivalwe ngoko nangoko xa kukho ukungasebenzi kakuhle. Phantsi kweemeko ezifanelekileyo zokugcina, i-TODI isebenza iinyanga ezintandathu ubuncinane ukususela kumhla efikelelwa ngawo.
