在云岗矿中学楼抹灰施工中,我处土建一工区在砂浆中加人微沫剂取得了良好的效果,目前已全面推广应用。 微沫剂是用有机高分子化合物制成的棕色透明状胶体,它在砂浆中产生大量稳定泡沫,促使砂浆中的胶结材料得到充分利用,从而提高了胶结性能。微沫剂的主要成分为氧化的脂酸类(C。。Hs。O。),是一种具有粘性的高分子胶体物质。当物体集中于两相界面时,形成网状分子结构,从而发生乳化、分散和起泡等作用。
In the construction of plastering in the middle school building of Yungang Coal Mine, the construction of a working area in the civil engineering area of the mine has achieved good results with the addition of micro-foam agents in the mortar. Currently, it has been widely applied. The microfoam is a brown transparent colloid made of an organic polymer compound, which produces a large amount of stable foam in the mortar, which promotes the full use of the cementitious material in the mortar, thereby improving the cementation performance. The main component of the microfoam is oxidized fatty acids (C.. Hs. O.), which is a viscous polymer colloidal substance. When the objects are concentrated on the two-phase interface, a net-like molecular structure is formed so that emulsification, dispersion, and foaming occur.
