菱苦土地面是以菱苦土为主要胶结料,锯末为主要填充料,加入适量氯化镁水溶液拌合,铺设于楼地面基层上,用玻璃抹子摊平,通过菱苦土与六水氯化镁(即3MgO和MgCl_2·6H_2O)起化合作用,在终凝前用钢抹子收浆压光而成。为使表面光滑、色泽美观,拌合时可加入少量滑石粉和无机矿物颜料。有时为了耐磨,还加入一些石屑或砂粒。菱苦土地面不仅具有隔音、耐火、不起灰等特点,而且还具有轻微弹性,使人感觉舒适。因此被用作一些轻工业厂房如棉纺厂、毛纺厂等地面,也被用于民用建筑如办 The bitter soil surface is made of magnesite as the main binder, and sawdust as the main filler. Add the appropriate amount of magnesium chloride aqueous solution and mix it. Lay it on the ground floor of the building, flatten it with a glass trowel, pass the magnesite and hexahydrate magnesium chloride ( In other words, 3MgO and MgCl_2·6H_2O) were used together to form a steel trowel to squeeze the pressure before final coagulation. In order to make the surface smooth and beautiful in color, a small amount of talcum powder and inorganic mineral pigments can be added during mixing. Sometimes in order to wear out, some stone chips or sand are added. The bitter land surface not only has the characteristics of sound insulation, fire resistance, and no ash, but also has a slight elasticity and makes people feel comfortable. Therefore, it was used as a ground for some light industrial plants such as cotton mills, wool mills, etc.
