Babban ingancin Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
A'A diisocyanate ne na musamman na aliphatic wanda za'a iya amfani dashi don shirya polymers tare da mahadi dauke da hydrogen mai aiki. Abu ne mai tsayin sarkar da ke da kashin bayan fatty acid dimer 36-carbon dimer. Babban tsarin sarkar yana ba daA'Amafi girman sassauci, juriya na ruwa da ƙarancin guba ga sauran isocyanates aliphatic.A'A ruwa ne mai ƙarancin danko wanda ke da sauƙin narkewa a cikin mafi yawan kaushi na polar ko maras iyaka. Domin shi aliphatic isocyanate, yana da halaye na rashin rawaya. Yana da fa'idodi da yawa na ƙarancin guba, mai sauƙin amfani, mai narkewa a cikin mafi yawan kaushi, lokacin amsawa mai sarrafawa da ƙarancin hankali na ruwa. Yana da wani hali kore biorenewable musamman isocyanate iri-iri, wanda za a iya amfani da ko'ina a masana'anta karewa, elastomers, adhesives da sealants, coatings, tawada da sauran sojoji da kuma farar hula filayen.
1. Fabric: DDI mu tare da ruwa sauƙi don zama emulsion mai ruwa, wanda ya sa masana'anta su zama santsi, al'ada, da ruwa.
2. PU guduro da Polyurea guduro, ta yin amfani da DDI iya zama tare da preformance na wadanda ba yellowing, m resilience, da extensile, high m, low ruwa m, kuma mafi anti-abrasivenesss, anti-sunadarai ƙarfi, da kuma anti-low zazzabi.
3. Amsa daHTPBdon zama kyakkyawan dacewa da sake kunnawa, PU da aka samar na iya zama maras nauyi mara nauyi, babu buƙatar wakili na filastik.
4. Tufafi. DDI polyurea shafi tare da kyakkyawan ƙarfi mai ƙarfi da tabbacin yanayi, waɗanda aka sauƙaƙe su da ƙarfe da itace ba tare da fashe ba.
