Organic silicon: chemically refers to contain Si - C key, and at least one organic compounds is directly linked to the silicon atoms, as a basic material, in the construction, electrical and electronic, spinning, weaving, light industry, chemical industry and other fields have a wide range of applications. In the field of waterproof plugging, common organic silicon materials are: silane solution, silicon resin, silicon resin emulsion, organic silicon powder, silicon a crylic-acid emulsion, silicone sealant, etc. , is the common characteristics of these materials have excellent hydrophobic property. Is all silicone manufacturer for the demonstration of 'lotus effect'. Especially be confused with inorganic silicon is we say normally organosilicon waterproofing agent. Namely methyl sodium silicate or potassium silicate. Methyl sodium silicate ( Potassium) The waterproof mechanism is generated on the surface of the base materials a few molecules thick layer of insoluble waterproof resin film, usually with 8 - use The water 10 times dilution. Often used in building materials waterproof, anti-fouling processing and exterior decorative surface waterproof. But this kind of material life won't last very long, especially in the exposure of ultraviolet radiation environment, the surface of hydrophobic effect, materials, waterproof properties is failed. Inorganic silicon: usually refers to is given priority to with sodium silicate, potassium silicate, lithium silicate, add some additives composite waterproofing agent. In the field of waterproof plugging, common inorganic silicon materials are: permanent condensate, water permeable crystallization type waterproof material, sodium silicate, etc. The waterproof mechanism is usually dehydration or in concrete capillary hole generated in the crystal to blocking channels, thus improve the compactness of concrete and the strength, permeability resistance, etc. 【 How to identify the organic silicone and inorganic silica gel 】 The outside, organic silicon and inorganic silicon from aqueous solution is colorless, tasteless; Construction equipment are predominantly or spray watering can. So it's hard to distinguish between the two from the senses. So, how to identify the organic silicon and inorganic silicon is the material? Hydrophobic organic silicon is? Water is the inorganic silicon? In fact can't simply to judge, so are hydrophobic and hydrophilic surface phenomena, one thousand two ingredients have? Can penetrate deeply and significantly improve internal pore structure of concrete must be inorganic silicon; On the contrary, has no effect on pore structure of concrete is silicone. Then you may have a doubt, the wool stoma of concrete is so small, how do I see pore structure have changed? Here I share with you two angles: 1. : from the standpoint of crystal hardening of concrete after soaking in solution, observe whether the concrete surface is white crystal will come. If you have, for the inorganic silicon, conversely for silicon with machine. From this perspective, I would like to be called organic silicon 'osmotic crystallization'; Called the inorganic silicon 'permeable crystallization. 2. From the perspective of base level requirements and maintenance: organic silicon usually require construction base level dry and dry after curing, and inorganic silicon requires construction base moist and wet curing after construction. 【 The advantages and disadvantages of organic silicone and inorganic silica gel. From apparent effect, organic silicon 'lotus effect', easy inspection; And inorganic silicon after spraying the naked eye is hard to tell the difference, it is not easy to test. The penetration depth, organic silicon is often in the concrete surface layer 1 - 2 mm in depth. Therefore, once the concrete surface wear, the waterproof effect is failed. While inorganic silicon can rely on the water as the carrier within 10 - to concrete 50 mm range, even if the surface wear off a few millimeters, also does not affect the waterproof effect. From the scope of application, organic silicon can only be used in external wall, roof and other parts of the face of the water, and the surface is not suitable for to do other waterproof layer or decorative layer. Welcomed and inorganic silicon can be used in the water can also be used in the back of the water, after inorganic silicon, the surface can also do other flexible waterproof layer or adornment layer, stick relay is not affected. Right from nature, organic silicon inside the concrete pore structure have any effect. While inorganic silicon can be compacted concrete pore structure, increase the strength and permeability resistance. From the point of life, the validity of the organic silicon often only six months to a year. And the life of the inorganic silicon could theoretically with structure of life. 【 Flexible use, organic combination of 】 Since organic silicone and inorganic silica gel the advantages and disadvantages of each have each, in practice we should combine the advantages of each material, foster strengths and circumvent weaknesses. Spray such as inorganic silicon to reinforced concrete as a whole to strengthen, then spray on the surface of organic silicon further protection on concrete. Silicon and inorganic or organic silicon in the process of material production is organically, form the final product has both the advantages of the two materials. This should be is the direction of material research and development.
