地下室防水材料的具体选择（Selection of waterproof material in basement） According to the characteristics of the initial engineering basement for commercial use, must determine the waterproof level two waterproof, waterproof measures in design of reinforced concrete self waterproofing, at least should use a flexible waterproof layer, in order to ensure the engineering quality, time limit for a project and convenient construction, by Party A and supervision units and construction units together confirm, selection of JS composite waterproof coating as the waterproof layer of the project. 1. material introduction: JS composite waterproof coating (two sets of polymer cement waterproof coating) is a kind of high efficient moisture proof, impermeability and plugging material developed by foreign advanced technology. This product is organic liquid (by polyacrylate, polyester acid ethyl ester emulsion copolymer) and inorganic powder (by high aluminum cement, such as arsenic iron powder as the filler), after the scene according to the proportion of mixing into putty shape, new waterproof coating construction. The main film-forming material for water emulsion polymer materials, cement and active substances as filler and coating by evaporation of water and inorganic hydraulic hydration reaction material and conjunctiva, is a kind of flexible organic materials and inorganic materials have advantages of good durability. 2. product packaging: liquid packaging for 30kg per barrel, powder packaging for 3 bags per box, 10kg per bag. 3., product characteristics: A. can be wet, dry, a variety of materials directly construction. B. non-toxic, harmless, pollution-free, convenient construction, short construction period, can be used for drinking water projects. C. coating is tough, high strength, water resistance, weather resistance and durability. It can be added with color. D. can be cemented and bonded with cement, mortar and various materials. 4., the main technical indicators: (7 days later) A. t
