Dimeryl Diisocyanate kounga teitei DDI CAS NO. 68239-06-5
KĀORE he diisocyanate aliphatic ahurei ka taea te whakamahi hei whakarite i ngā pūhui me ngā matū kei roto te hauwai hohe. He matū mekameka roa me te tuara waikawa ngako dimer 36-waro. Ko te hanganga mekameka matua e homai ana KĀORE he tino ngāwari, he ātete ki te wai, he iti hoki te paitini ki ētahi atu isocyanates aliphatic. KĀORE He wai matotoru iti tēnei, he ngāwari te wairewa ki te nuinga o ngā whakarewa pōro, kore-pōro rānei. Nā te mea he isocyanate aliphatic, he āhuatanga kore-kōwhai tōna. He maha ngā painga o te iti o te paitini, te ngāwari ki te whakamahi, te wairewa ki te nuinga o ngā whakarewa, te wā tauhohenga ka taea te whakahaere, me te iti o te aro ki te wai. He momo isocyanate motuhake kakariki ka taea te whakahou koiora, ka taea te whakamahi whānuitia ki te whakaoti kakahu, ki ngā elastomers, ki ngā piripiri me ngā hiri, ki ngā paninga, ki ngā waituhi me ētahi atu mara hōia me ngā mara ā-iwi.
1. Kakahu: ko tā mātou DDI me te wai he ngāwari ki te waiho hei whakaehu wai, i maeneene ai te papanga, kia ngawari, kia ātete hoki ki te wai.
2. Mā te whakamahi i te kapia PU me te kapia Polyurea, ka taea te whakamahi i te DDI me te āhua kore-kōwhai, he tino pakari, he whānui, he pakari, he iti te aro ki te wai, ā, he pai ake te ārai-kiri, te whakarewa matū, me te pāmahana iti.
3. Tauhohe ki HTPB kia tino hototahi ai, kia tino tauhohe hoki, ka taea e te PU kua hangaia te tino pakari, kāore e hiahiatia he kirihou.
4. Paninga. He paninga polyurea DDI me te kaha kume tino pai me te ātete ki te huarere, e ngāwari ana te piri ki te whakarewa me te rakau, kāore he whati.
