摘　　要：不同种类的甲酸吸收剂对共聚甲醛的影响有很大的差异。主要研究了硬脂酸盐类、金属氧化物、酸吸收剂A(国产)、酸吸收剂B(德国科莱恩)等甲酸吸收剂对聚甲醛的黄色指数、甲醛和甲酸吸收效果以及低碳钢板腐蚀程度的影响。综合分析表明,硬脂酸盐类作为聚甲醛的甲酸吸收剂效果最差,而酸吸收剂A是聚甲醛最合适的甲酸吸收剂,其不会改变POM的白度,可大幅度降低甲醛含量,且对碳钢的腐蚀程度最弱。The effects of different types of formic acid absorbers on copolyoxymethylene(Co-POM)were significantly different.The effects of stearic acid,metal oxide,formic acid absorber A,and formic acid absorber B on the yellow index of polyoxymethylene,the absorption of formaldehyde and formic acid and the corrosion degree of low carbon steel plate were studied.The comprehensive analysis shows that stearic acid is the worst formic acid absorbent for polyoxymethylene,and formic acid absorber A is the most suitable formic acid absorbent,which could not change the whiteness of POM,greatly reduce the formaldehyde content and the corrosion of carbon steel is the weakest.
