Zipangizo za polyurethane zapamwamba kwambiri komanso ma isocyanates apadera 1,5-Naphthalene Diisocyanate(NDI) CAS 3173-72-6

NDI (1,5-Naphthalene Diisocyanate) ndi zinthu zopangidwa ndi polyurethane yapamwamba, zomwe zingagwiritsidwe ntchito popanga polyurethane elastomer yokhala ndi kusinthasintha kwakukulu komanso kuuma kwambiri. NDI polyurethane elastomer ili ndi magwiridwe antchito abwino kwambiri. Ili ndi magwiridwe antchito osayerekezeka ndi ena onse a polyurethane elastomer, monga magwiridwe antchito abwino kwambiri, magwiridwe antchito apamwamba kwambiri, kukana kudula bwino, kukana kuvala komanso kukana kutentha. Chifukwa chake, NDI polyurethane elastomers imagwiritsidwa ntchito kwambiri mu ma absorbers a magalimoto, ma forklift bearing wheels, kusindikiza ndi kuyika utoto ma roller a rabara a nsalu, zokwapula rabara, ma buffer blocks omanga mlatho, makampani ankhondo, ndi zina zotero.

Elastomer yopangidwa ndi NDI ili ndi mawonekedwe abwino kwambiri osinthika komanso kukana kuwonongeka, komanso imakhala ndi chinyezi chochepa, kupirira kwambiri, komanso kutentha kochepa mkati. Itha kugwiritsidwa ntchito nthawi zambiri pamavuto amagetsi komanso nthawi zina zosagwirizana ndi kutentha. Zinthu zopangidwa ndi NDI zimakhala ndi mphamvu yong'ambika kwambiri, kusweka kochepa, kupsinjika kochepa komanso kupirira bwino. Zinthu zopangidwa ndi NDI zokhala ndi ma microporous polyurethane elastomer zimakhala ndi kutentha kochepa, kusinthasintha kochepa komanso kulimba bwino pansi pa mphamvu yamagetsi. Zipangizo zapadera za polyurethane zopangidwa ndi microporous zimagwiritsidwa ntchito makamaka poyamwa ndi kutsika kwa magalimoto.
