Zinthu zapamwamba za Polyurethane ndi isocyanates yapadera 1,5-Naphthalene Diisocyanate(NDI) CAS 3173-72-6

NDI (1,5-Naphthalene Diisocyanate) ndi zida zapamwamba za polyurethane, zomwe zitha kugwiritsidwa ntchito popanga elastomer ya polyurethane yokhala ndi kutsika kwambiri komanso kulimba kwambiri. NDI polyurethane elastomer ili ndi ntchito yabwino kwambiri. Ili ndi magwiridwe antchito osayerekezeka ndi elastomer ina iliyonse ya polyurethane, monga magwiridwe antchito apamwamba kwambiri, magwiridwe antchito apamwamba kwambiri, kukana kodula bwino, kukana kuvala komanso kukana kutentha. Chifukwa chake, NDI polyurethane elastomers amagwiritsidwa ntchito kwambiri pamakina otsekera magalimoto, mawilo onyamula forklift, kusindikiza ndi kudaya zodzigudubuza zalabala, zomangira mphira, midadada yomanga mlatho, mafakitale ankhondo, ndi zina zambiri.

Elastomer yonyezimira yopangidwa ndi NDI ili ndi mawonekedwe abwino kwambiri komanso kukana kuvala, komanso yonyowa pang'ono, yolimba kwambiri, komanso kutentha pang'ono mkati. Itha kugwiritsidwa ntchito paziwongola dzanja zambiri komanso nthawi zolimbana ndi kutentha. Zopangira zopangidwa ndi NDI zimakhala ndi mphamvu zong'ambika kwambiri, zopweteka pang'ono, zoponderezedwa pang'ono komanso zolimba kwambiri. Zopangidwa ndi NDI-zochokera ku microporous polyurethane elastomer zimakhala ndi kutentha pang'ono kwamkati, kapindika kakang'ono kokhazikika komanso kukhazikika bwino pansi pa katundu wosunthika. Chapadera ichi cha microporous polyurethane chimagwiritsidwa ntchito makamaka pamayamwidwe agalimoto ndi zida zomangira.
