摘　　要：以聚酯多元醇、TDI、MOCA为原料研制了弛张筛板用浇注型聚氨酯弹性体。采用离心浇注法成型。讨论了原料、配方和成型工艺对弛张筛板性能的影响。所研制的筛板性能优异、质量稳定、使用寿命半年以上。Polyurethane elastomers used for relaxation sieve-plates were prepared from polyester polyol, toluene diisocyanate and methylene bis-ortho-chloro-aniline. The technique of centrifugal casting was used. The effects of raw materials, formulation and production techniques on the properties of the relaxation sieve-plates were discussed.The sieve-plates have excellent property, stable quality and longer service life.
