影响A(D)C发泡剂粒径因素的探讨

Study on the factor of affecting the A(D)C blowing agent particle size

A(D)C发泡剂的粒径对其发泡速度以及发气量等产生很大影响 ,通过在联二脲氧化阶段的反应温度、催化剂的加入量、添加不同的表面活性剂等的研究 ,探索出影响A(D)C发泡剂的粒径的规律 ,以适应市场的不同需求。

The particle of A(D)C blowing agent has a great effect on its foaming velocity, foaming volume and so on. The reaction temperature, catalyst quantity and different added superficial activated agents were studied during the period of the oxidation of biurea.The rule which effected the particle of A(D)C blowing agent was explored to suit different demands of the market.
