Elastomer ya polyurethane PU, ndi mtundu wa rabala yokhala ndi mphamvu yabwino komanso kusintha pang'ono kwa kupsinjika. Mtundu watsopano wa zinthu pakati pa pulasitiki ndi rabala, womwe uli ndi kulimba kwa pulasitiki komanso kusinthasintha kwa rabala.
Dzina lachi China: Polyurethane PU elastomer
dzina lachibwana: Kugwiritsa ntchito guluu m'malo mwa rabara
Chipepala cha PU chili ndi makhalidwe monga kuphimba, bata, kuyamwa kwa mantha, kukana kuvala, kukana kutentha kwambiri, ndi zina zotero. Ndi cholimba komanso choyenera kuteteza pamwamba pa zida m'malo ogwirira ntchito a asidi ndi alkali, pomwe chikukweza kukana kwa zida ndikuchepetsa phokoso. Ma board a PU, ndodo, mapepala, ndi zina zotero. Kulimba kwamphamvu kobwezeretsa, kumatha kupanikizika ndi 50%; mphamvu yayikulu, yolimba, sikungasinthidwe ndi zinthu monga rabara. Kukana kuthamanga ndi kugwedezeka, kukana kugunda, kukana mafuta, kukana asidi ndi alkali, kukana bwino kuvala. Ma elastomer a mndandanda wa PU ali ndi mphamvu yayikulu yolimba, kukana kung'ambika, kukana kupanikizika kwambiri, kukana kupanikizika kwambiri, kukana kuvala, ndi zina zotero, ndipo ndi osavuta kudula, kupukuta, kubowola, ndi zina zotero, ndipo amatha kugwiritsidwa ntchito pazinthu zamakina, zinyalala, Recoil pad, kupindika. Zisindikizo ndi zolumikizira za mano zomwe zimagwiritsidwa ntchito pamakina ndi zida zamafakitale. Zimagawidwa m'mitundu yolimba mafuta ndi yolimba. Kuuma kwake kuli pakati pa Shore 25 ndi Shore 98. Ili ndi mphamvu yabwino komanso magwiridwe antchito otupa. Itha kugwiritsidwa ntchito nthawi zambiri m'malo okhala ndi kukana kukalamba bwino komanso moyo wautali wautumiki. , Mafotokozedwe ambiri azinthu, mitundu yonse.
