Yuan Lei told you | about flexible waterproof coating, you should know this knowledge


Waterproof coating is a kind of fluid or semi fluid material, can be used to brush, spray and other process coating on the surface of the base layer to form a protective layer, so that the surface of the base layer and water isolation, play the role of waterproof and moisture-proof, widely used in building waterproof engineering.

Flexible waterproof coating has the following categories: polymer waterproof coating, polyurethane waterproof coating, acrylic waterproof coating, water emulsion asphalt waterproof coating.

Common points of flexible waterproof coatings in building waterproofing:

1. The waterproof membrane formed by the flexible waterproof coating has good extensibility, water resistance and weather resistance, and the waterproof effect is good.

2, the waterproof layer of light weight, especially suitable for light roof waterproof.

3, the construction is convenient, it can not only in the horizontal plane, but also in the facade, yin and yang angle and various shapes of complex surface construction, forming a seamless, complete waterproof coating.

4. The waterproof coating on the base layer is not only the main material of the waterproof layer, but also a kind of binder with good performance. Can be used for base cracks, construction joints, rainwater bucket and through the pipeline around, etc., paste the carcass reinforcement material, convenient construction, waterproof plugging effect is good.

5, the use of flexible coating waterproof, maintenance is more convenient.

No heating is required during use, which not only reduces environmental pollution, but also facilitates construction operations and improves working conditions.


Waterproof coating selection should pay attention to the following aspects:

1, wet base should be selected and wet base bonding force of inorganic waterproof coating or organic waterproof coating, inorganic waterproof coating can also be used after coating organic waterproof coating composite waterproof coating;

2. For important projects with deep embedding depth, projects with vibration or large deformation, high elastic waterproof coating should be selected;

3, corrosive underground environment should choose good corrosion resistance of organic waterproof coating, should also do a rigid protective layer;

4, home decoration waterproof should choose polymer cement waterproof coating.

Flexible waterproof coating construction matters needing attention:

1. Fully stir the paint. Pour the liquid additive into a clean mixing container, and then slowly add the powder while stirring according to the proportion, and fully stir until a powder-free, uniform mucilage is generated, and it is used up within the operating time.

2, dealing with special parts. Pipe roots, yin and yang angles, floor drains, etc. are invited to be plugged tightly with plugging king, etc., and carcass reinforcement materials are added, and 2 or more layers are painted according to the use environment and performance requirements.

3, carefully do the second layer of waterproof coating. After finishing one layer, you must wait until it is slightly dry and solid, and then do the second layer when it is just not sticky. If more than 24 hours, or the coating has been cured, the second layer on it, you must first use water to re-wet the surface.

4. Curing and curing. From the second day after the slurry is applied, it is recommended to cover the coating with fine mist spray or wet cloth for 2-3 days, and then carry out closed water test. For long-term water-filled pools, water should be filled only after they are vacant for two weeks. The stirred slurry should generally be used up within 1 hour, and the solidified materials cannot be reused. Do not mix water and stir, and do not change the proportion of emulsion at will.

After the construction is completed, immediately clean all tools and equipment with water.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Source Lei gas barium sulfate ten uses


Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
