摘要
针对设计的一种孔隙式发泡器,运用理论研究与实验相结合的方法,系统地研究了该发泡器的理论与工艺。实验结果表明:不同压缩空气流量下,产生的水基泡沫流量随发泡剂稀释液流量的增加而增加;产生的水基泡沫发泡倍数和稳定时间(半衰期)随发泡剂稀释液流量的增加呈现先增大后减小的关系;最佳发泡剂稀释液流量为0.3~0.5 m3/h,为制备泡沫浆体材料提供了依据。
Designed a kind of pore type foam generator, using the method of theoretical research and experiment, systematically studies the theory and technology of foam generator. The experimental results show that, under different compressed air flow, aqueous foam flow increases with the increase of foaming agent of diluent flow. The expansion ratio of aqueous foam and stable time (half-life) with the increase of foaming agent diluent flow first increases then decreases. The best foaming agent diluent flow is 0.3~0.5 m3/h, the experimental results provided the basis for preparation of foam slurry material.
