浅析聚氨酯鞋底生产过程中影响质量的因素

THE EFFECTIVE FACTORS ON QUALITY OF PU SHOE SOLE

研究分析了聚氨酯(PU)鞋底生产过程中影响产品质量的主要因素。实践证明:多元醇组分(A液)与异氰酸酯组分(B液)的配比是生产中的关键。准确掌握原液质量,严格控制生产温度,尽量维持系统内压力恒定,以确保A、B液配比在一定范围内,才能生产出合格的聚氨酯鞋底。

The effective factors on the quality of polyurethane shoe sole in the production were analysed. The practise showed that the key in production is the ratio of liquid A (multi - glycol) to liquid B (isocyanates). Only when the quality of original liquid was stabilized, the production temperatures were strictly controlled and the ratio of liquid A to liquid B was ensured in a certain range, could the PU shoe sole with high quality be produced.
