Te kounga teitei Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
NO he diisocyanate aliphatic ahurei ka taea te whakamahi ki te whakarite waerau me nga pūhui kei roto te hauwai kaha. He pūhui mekameka roa me te tuara o te waikawa momona 36-waro dimer. Ko te hanganga mekameka matua e homaiNOte ngawari, te aukati wai me te iti o te paitini ki etahi atu isocyanates aliphatic.NO he wai pokey iti he ngawari te whakarewa i te nuinga o nga whakarewa polar, kore-polar ranei. Na te mea he isocyanate aliphatic, he ahua kowhai-kore. He maha nga painga o te paitini iti, te ngawari ki te whakamahi, te wairewa i roto i te nuinga o nga whakarewa, te wa tauhohenga whakahaere me te iti o te tairongo wai. He momo isocyanate motuhake te koiora matomato, ka taea te whakamahi whanui ki te whakaoti papanga, elastomers, adhesives me sealants, paninga, waituhi me etahi atu mara hoia me te iwi.
1. papanga: to tatou DDI ki te wai ngāwari ki te whakaehunga wai, i hanga te papanga kia maeneene, tauiwi, me te wai-tohu.
2. PU resin me te Polyurea resin, te whakamahi i te DDI ka taea te ki te preformance o kore-kowhai, pai resilience, me te extensile, teitei mārō, iti wai whai whakaaro, me te pai anti-abrasivenesss, whakarewa anti-matū , me te anti-iti pāmahana.
3. Tauhohe meHTPBkia pai ai te hototahi me te tauhohenga, ko te PU kua puta he tino iti te maataki, kaore he kaihoko kirihou.
4. Te paninga. Ko te paninga polyurea DDI me te kaha kaha me te tohu huarere, he ngawari ki te piri ki te whakarewa me te rakau kaore he pakaru.
