Polyurethane

Igikoresho cya polyurethane kitagira amazi ni ubwoko bwa prepolymer irimo Isocyanate itegurwa hiyongereyeho polymerisation ya Isocyanate, polyether nibindi, hamwe na catalizator, inyongeramusaruro ya anhydrous, ibikoresho byuzuza anhydrous, ibishishwa, nibindi, igipande kimwe cya polyurethane kitagira amazi gikozwe mukuvanga nibindi. inzira.Ubu bwoko bwo gutwikira ni reaction-ikiza (moist-curing) itwikiriye imbaraga nyinshi, kuramba cyane, kurwanya amazi meza nibindi.Guhuza cyane no guhindura imizi y'ibyatsi.Igikoresho cya polyurethane kitagira amazi ni ubwoko bumwe bwibice byo kurengera ibidukikije bitangiza amazi bikoreshwa mumazi.Ishingiye kuri polyurethane itumizwa mu mahanga idafite tar na asfalt.Nubushuhe buri mu kirere nyuma yo guhura gukira, hejuru yigitereko kugirango habeho urwego rukomeye kandi rukomeye rutagira anti-firime.
