[Izakhiwo Zamakhemikhali]

I-Toluene diisocyanate ikhona ngezindlela ezimbili ze-isomere (2,4-toluene diisocyanate kanye ne-2,6-toluene diisocyanate), ezinezakhiwo nemiphumela efanayo. I-Toluene diisocyanate ikhiqizwa ngokwezentengiselwano njengengxube engu-80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) yama-isomers amabili. Ezingeni lokushisa legumbi, ingxube iwuketshezi oluphuzi olucacile, olukhanyayo olunephunga elibukhali nelinomunyu. Kufanele igcinwe ngaphansi kwesiqandisi, kude nokukhanya nomswakama esitsheni esivalwe kahle endaweni epholile. I-Toluene diisocyanate ayincibiliki emanzini futhi ixutshwa nezinyibilikisi eziningi eziphilayo. I-Toluene diisocyanate yenziwa ngokuphendula i-toluene diamine ne-carbonyl chloride (phosgene). I-Toluene diisocyanate ivame ukusetshenziswa njenge-intermediate yamakhemikhali ekukhiqizweni kwama-polyurethane foam, ama-elastomer, kanye ne-coatings, upende, ama-varnish, ama-wire enamel, ama-sealant, ama-adhesive, kanye nama-binder. Iphinde isetshenziswe njenge-ejenti yokuxhumanisa ekukhiqizweni kwama-polymer e-nylon. I-2,4-Toluene diisocyanate isetshenziswa njenge-intermediate yamakhemikhali ekukhiqizweni kwemikhiqizo ye-polyurethane, njenge-foam, i-coatings, kanye ne-elastomers.

Ekwenziweni kwama-polyurethane foams namanye ama-elastomer.

I-asthma yomsebenzi iyimbangela eyinhloko yesifo sokuphefumula esihlobene nomsebenzi ezweni lezimboni. I-Toluene-2,4-diisocyanate (TDI) ingenye yezinto ezivame kakhulu ukuzwela ukuphefumula okuholela ku-asthma yomsebenzi.

I-TDI (i-toluene diisocyanate) iyinto ebalulekile eyisisekelo yokusetshenziswa kwe-polyurethane. I-TDI iyinhlanganisela yezinhlobo ezimbili ze-isomers ezingama-2,4-TDI kanye ne-2,6-TDI, okuhlanganisa izinhlobo ezintathu zezinhlobo ezivame ukusetshenziswa: i-TDI-80/20, i-TDI-100 kanye ne-TDI-65/35. Isetshenziswa kakhulu ekukhiqizweni kwe-polyurethane foam eguquguqukayo kanye ne-polyurethane elastomer coating, izinamathiselo, njll.

I-Toluene-2,4-diisocyanate ingenye yama-isocyanate asetshenziswa kakhulu. Isetshenziswa ekukhiqizeni amagwebu aqinile futhi aguquguqukayo, ama-elastomer, kanye nezingubo. Ngaphezu kokusetshenziswa kwayo njengenhlanganisela emsulwa, itholakala kwezentengiselwano njengengxube yama-isomers angu-2,4- kanye nama-2,6 (80:20% kanye nama-65:35% ratios, ngokulandelana).
