Tirohanga Whānui o te Hua

He rauemi matū waro nui te Toluene Diisocyanate (TDI), e puta mai ana i te tauhohenga o te toluene diamine me te phosgene. Hei wāhanga matua i roto i te hanga polyurethane, e whakamahia whānuitia ana te TDI i roto i ngā pahuka ngāwari, ngā paninga, ngā piripiri, ngā elastomers, me ētahi atu. E rua ngā āhua isomeric matua o te TDI: TDI-80 (80% 2,4-TDI me te 20% 2,6-TDI) me te TDI-100 (100% 2,4-TDI), ko te TDI-80 te momo ahumahi e whakamahia whānuitia ana.

Ngā Āhuatanga Matua

• Te Tauhohenga Teitei:Kei roto i te TDI ngā rōpū isocyanate tino tauhohe (-NCO), ka taea te tauhohe ki te hydroxyl, amino, me ētahi atu rōpū mahi hei hanga rauemi polyurethane.
• Ngā Āhuatanga Mīhini Pai Rawa:He tino ngāwari, he ātete ki te kakahu, he kaha hoki ki te haehae ngā rauemi polyurethane.
• Te Matotoru Iti:He ngāwari ki te tukatuka me te whakaranu, he pai mō ngā momo tukanga whakaputa.
• Te pumau:He pumau i raro i ngā tikanga rokiroki maroke engari me pupuri kia matara atu i te makuku.
