Tšebeliso ea Lihlahisoa
HQEE ke symmetrical monko o monate oa diol extender. E ka ntlafatsa maemo a thata, a thata, a mahlahahlaha ho MDI-polyurethane elastomers. HQEE/MDI ke letoto la PU elastomer le tsamaisanang le MOCA/TDI. Lihlahisoa tse felileng e le: litiiso tsa liliba tsa oli, lithaere tsa forklift, lebanta la conveyor, litiiso tsa hydraulic cylinder le lihlahisoa tse ling tse ngata tsa PU.
Li-elastomers tsa LCU li hloka likarolo tse peli tsa motheo: prepolymer e felisitsoeng ka lihlopha tse sebetsang tsa isocyanate le ketane e sa sebetseng ea hydrogen-terminated chain extender. Prepolymer ke sehlahisoa se ipapisitseng le karabelo ea polyester kapa polyether e nang le isocyanate (TDI, MDI, ADI). The chain extender hangata ke ketane e khuts'oane ea diamine kapa diol. Li-prepolymer tsa MDI hangata li atolosoa ka diol.
Sephutheloana le Polokelo
Sephutheloana:
25kg / moropa oa lebokose kapa joalo ka litlhoko tsa hau.
Tlhokomeliso: Sebopeho le boholo ba lik'hemik'hale li ka ntlafatsoa ho latela litlhoko tsa bareki
Polokelo:
Lula u koetsoe ka thata. HQEE e na le hygroscopic 'me e tla fetola' mala tlas'a khanya ea letsatsi. Lula u koetsoe ka thata 'me u boloke sebakeng se nang le moea o motlakase. Boloka hole le mongobo le khanya ea letsatsi
