concrete surfaces enclosing class waterproofing agent

 Concrete surfaces enclosing class waterproofing agent is applied to the  concrete surface coated with a PVC stabilizer for cable  layer of a surface layer can penetrate into the pores of manipulation
Hydrophobic waterproof material, such as commonly used in China silicone waterproofing agent, silicate-containing water agent, and the foreign
Acrylic acid methyl ester monomer with waterproof Qi cracking and so on. 1 penetrate the surface of the Glycerol monostearate  closed water causes and mechanism of concrete seepage
Mainly due to external pressure, or because the pores of which the concrete surface adsorbed water, or because the two integrated
Cooperation with. Pore ​​water is due to the pores on the surface acting on the surface tension of water in the concrete grout
The driving force generated within the adsorbed water with the rules. Concrete interface between water and the aluminium hydroxide  contact angle of the meniscus is generally less than 90 degrees, the force
Could drive water into the pores which can wet surfaces. When using a certain way
(A) General coagulation on the surface of the twisted 90 ') Tian a contact angle (on concrete
Soil surface moist and pores filled with the composition of the soil water repellent reaction or because the chemical properties of the concrete itself
Soil pores (micropores, pores, etc.) and the water contact angle is increased to more than 90 degrees ...
