Dimeryl Diisocyanate DDI CAS NO. Yemhando yepamusoro 68239-06-5
AIHWA imhando yakasiyana ye aliphatic diisocyanate inogona kushandiswa kugadzira ma polymer ane makemikari ane active hydrogen. Imhando ye chain-long ine musana we 36-carbon dimer fatty acid. Chimiro chikuru che chain chinopa AIHWA kuchinjika kwakanyanya, kuramba mvura uye kuchetura kushoma kune mamwe ma-isocyanates e-aliphatic. AIHWA imvura ine viscosity yakaderera iyo inonyungudika nyore nyore muzvinyungudutsi zvakawanda zve polar kana zvisiri polar. Nekuti i aliphatic isocyanate, ine hunhu hwekuti haitsvedzerere. Ine mabhenefiti akawanda ekuti ine chepfu shoma, iri nyore kushandisa, inonyungudika muzvinyungudutsi zvakawanda, inodzoreka nguva yekuita uye ine mvura shoma. Imhando yakajairika ye green biorenewable special isocyanate, iyo inogona kushandiswa zvakanyanya mukupedzisa machira, elastomers, adhesives uye sealants, coatings, inks nedzimwe nzvimbo dzemauto nedzehurumende.
1. Jira: DDI yedu ine mvura iri nyore kushandisa kuti ive emulsion yemvura, izvo zvakaita kuti jira rive rakatsetseka, rakapfava, uye risingapindi mvura.
2. PU resin uye Polyurea resin, uchishandisa DDI inogona kunge isina kutsvuka, yakasimba zvakanyanya, uye yakakura, yakasimba, ine mvura shoma, uye inodzivirira kupwanyika zviri nani, inodzivirira makemikari, uye inodzivirira kupisa kwakaderera.
3. Ita chimwe chinhu ne HTTPB Kuti ienderane zvakanaka uye iite reactivity, PU inogadzirwa inogona kunge isina kuoma zvakanyanya, hapana chikonzero chepurasitiki.
4. Kuputira. Kuputira kweDDI polyurea kwakasimba uye kunodzivirira mamiriro ekunze, izvo zvinonamira nyore nyore pasimbi nematanda pasina kutyoka.
