[Ngā Āhuatanga Matū]

E rua ngā āhua isomeric o te toluene diisocyanate (2,4-toluene diisocyanate me te 2,6-toluene diisocyanate), he rite tonu ngā āhuatanga me ngā pānga. Ka hangaia te toluene diisocyanate hei ranunga 80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) o ngā isomers e rua. I te pāmahana rūma, he wai mārama, he kōwhai mā te ranunga, he kakara koi, he kakara kaha. Me rongoa i raro i te pouaka whakamātao, kia matara atu i te mārama me te makuku i roto i tētahi ipu kua kati pūmau i roto i tētahi hau kore mahi. Kāore te toluene diisocyanate e rewa i roto i te wai, ā, ka taea te whakaranu ki te nuinga o ngā whakarewa waro noa. Ka hangaia te toluene diisocyanate mā te tauhohe i te toluene diamine me te carbonyl chloride (phosgene). He mea whakamahi noa te toluene diisocyanate hei takawaenga matū i roto i te hanga pahuka polyurethane, elastomers, me ngā paninga, peita, wanihi, enamel waea, hiri, piripiri, me ngā here. Ka whakamahia hoki hei āpiha honohono i roto i te hanga i ngā pūmua nairona. Ka whakamahia te 2,4-Toluene diisocyanate hei takawaenga matū i roto i te hanga hua polyurethane, pērā i te pahuka, te paninga, me ngā elastomers.

[Ngā Whakamahinga]

I roto i te hanga o ngā pahuka polyurethane me ētahi atu elastomers.

[Ngā Whakamahinga]

Ko te mate huango mahi te tino take o ngā mate manawa e pā ana ki te mahi i roto i te ao ahumahi. Ko te Toluene-2,4-diisocyanate (TDI) tētahi o ngā mea whakaoho manawa e tino kitea ana e arahi ana ki te mate huango mahi.

[Ngā Whakamahinga]

Ko te TDI (toluene diisocyanate) he rauemi matua nui mō te hanga polyurethane. Ko te TDI he ranunga o ngā momo isomers e rua o te 2,4-TDI me te 2,6-TDI, tae atu ki ngā momo momo e toru e whakamahia whānuitia ana: TDI-80/20, TDI-100 me te TDI-65/35. E whakamahia whānuitia ana mō te hanga pahuka polyurethane ngāwari me ngā paninga elastomer polyurethane, ngā piripiri, me ētahi atu.

[Ngā Whakamahinga]

Ko te Toluene-2,4-diisocyanate tētahi o ngā isocyanate e whakamahia whānuitia ana. E whakamahia ana hei hanga i ngā pahuka urethane pakari me te ngāwari, ngā elastomers, me ngā paninga. Haunga tōna whakamahinga hei matū parakore, kei te wātea arumoni hei ranunga o ngā isomers 2,4- me 2,6- (ōwehenga 80: 20% me 65: 35%, ia).
