ʻO Dimeryl Diisocyanate DDI CAS NO. 68239-06-5 ke kūlana kiʻekiʻe
ʻAʻOLE he aliphatic diisocyanate kū hoʻokahi ia e hiki ke hoʻohana ʻia e hoʻomākaukau i nā polymers me nā hui i loaʻa ka hydrogen hana. He hui kaulahao lōʻihi ia me kahi iwi kuamoʻo dimer fatty acid 36-carbon. Hāʻawi ke ʻano kaulahao nui ʻAʻOLE ʻOi aku ka maʻalahi o ka loli, ke kūpaʻa wai a me ka haʻahaʻa o ka ʻawahia i nā isocyanates aliphatic ʻē aʻe. ʻAʻOLE He wai haʻahaʻa ka mānoanoa e hiki ke hoʻoheheʻe maʻalahi i ka hapa nui o nā mea hoʻoheheʻe polar a i ʻole non-polar. No ka mea he aliphatic isocyanate, loaʻa iā ia nā ʻano o ka non-yellowing. He nui kona mau pono o ka haʻahaʻa haʻahaʻa, maʻalahi e hoʻohana, hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe, ka manawa hopena hiki ke hoʻokele ʻia a me ka haʻahaʻa o ka wai. He ʻano isocyanate kūikawā biorenewable ʻōmaʻomaʻo maʻamau, hiki ke hoʻohana nui ʻia i ka hoʻopau ʻana i ka lole, nā elastomers, nā mea hoʻopili a me nā mea hoʻopaʻa, nā uhi, nā inika a me nā kahua koa a me nā kahua kīwila ʻē aʻe.
1. lole: ʻo kā mākou DDI me ka wai e maʻalahi e lilo i emulsion wai, ka mea i hana i ka lole e laumania, lokomaikaʻi, a me ka wai-hōʻoia.
2. ʻO ka resin PU a me ka resin Polyurea, me ka hoʻohana ʻana i ka DDI hiki ke hana me ka preformance o ka non-yellowing, resilience maikaʻi loa, a me ka extensile, paʻa kiʻekiʻe, haʻahaʻa ka wai naʻauao, a ʻoi aku ka maikaʻi o ka anti-abrasivenesss, anti-chemical solvent, a me ka anti-low temperature.
3. E pane me HTPB i mea e kūpono ai a me ka pane ʻana, hiki i ka PU i hana ʻia ke haʻahaʻa haʻahaʻa loa, ʻaʻohe pono o ka mea hana plastik.
4. Uhi ʻana. ʻO ka uhi polyurea DDI me ka ikaika tensile maikaʻi loa a me ka pale ʻana i ka wā, kahi e maʻalahi ai ke hoʻopili ʻia i ka metala a me ka lāʻau me ka ʻole o ka haki.
