【摘要】：為提高泡沫材料的發(fā)泡倍數(shù)并降低成本,進行了固體泡沫特性及其添加無機物(黃沙)的實驗研究.通過分析原料A馬麗散與發(fā)泡劑B在不同配比下混合及混合加沙后固體泡沫的發(fā)泡特性,找出最佳配比和最佳含沙質量分數(shù)使發(fā)泡倍數(shù)最大,對比分析添加無機物前后的經(jīng)濟成本,并在天池礦102尾巷采空區(qū)進行了現(xiàn)場應用研究.結果表明:原料A馬麗散、發(fā)泡劑B的最佳配比為1:1.2,當含沙質量分數(shù)為25%時發(fā)泡倍數(shù)最大為14.220且防滅火效果較好.
[Abstract]:In order to improve the foaming ratio of foam materials and reduce the cost, the properties of solid foam and the addition of inorganic material (yellow sand) were studied. By analyzing the foaming characteristics of solid foams mixed with foaming agent B and raw material A Marisan and mixed with Gaza in different proportions, it was found out that the best mix ratio and the best mass fraction of sand had the highest foaming multiple. The economic cost before and after the addition of inorganic matter was analyzed, and the field application study was carried out in 102 mined-out areas of Tianchi Coal Mine. The results show that the best ratio of foaming agent B is 1: 1.2, when the mass fraction of sand is 25, the maximum foaming multiple is 14.220 and the fire extinguishing effect is better.
