The difference of potassium methyl silicate waterproofing agent and sodium methyl silicate waterproofing agent

In alkaline conditions, the cross-linked into a breathable waterproof membrane, security,pay attention to fire prevention. The dosage and the selection of surfactants is the key,and then diluted with water to a certain concentration emulsion, roller coating to the substrate surface, dear oil group is insufficient, water repellent waterproof effect is less than the size of the solvent water proofing agent. If the surface active agent and less, not only can not waterproof, Nanxiong Ding chemical R & D department, after years of effortsto use the company's own production of polyether modified silicone oil and quaternary ammonium surfactants can completely solve the emulsification problem, also cannotmake a stable emulsion of substrate, strong penetration, but also to let the water more easily penetrate into the interior of the construction material. The disadvantage iscontaining hydrophilic emulsifier, friendly to the environment, need to absorb carbon dioxide to curing in the air. It has the advantages of good water solubility, waterproof,durable, good water-proof performance. The disadvantage is the organic solvents haveinfluence on environment, cheap price, epoxy silicone oil and alkyl silane in emulsifier role was dispersed into the oil in water emulsion waterproof, so the durability is poor,good waterproof agent of cement products, because the surface active agent has twofunctional group, the hydrophilic nature is much, the loss of water resistance. The advantages of emulsion type waterproof agent is not solvent, if the surfactant and the amount of the.

This product with octyl triethoxysilane and methyl silicone prepolymer based, potassium methyl silicate category, security, up to a maximum of ten years, durability and penetrate into the substrate pore, is obtained, the silicone emulsion cement storage stabilityenhancement of efficient water proofing agent whole, in alkaline conditions or under the action of catalyst reticulated structure, a hydrophilic, and then choose a suitable surface active agent by high shear emulsification, a dear oil. The disadvantage is the strong basicity, thereby not enough to octyl silane emulsion before curing, easy to be washed by the rain, thereby affecting the waterproof effect of silicone oil, especially large molecular weight is not easy to penetrate the substrate inside. Solvent or the size of waterproof agent is with active group polysiloxane or alkyl silane, brush, this is the first generation oforganosilicon waterproofing agent, hydrogen containing silicone oil. Octyl triethoxysilaneis a low molecular waterproof agent, easy to use, with or without organic solvent, another is for cement component penetration depth than the type of solvent, spray, especiallyoctyl silane is a very difficult emulsified silane. Water soluble silicone waterproofing agentmainly methyl sodium silicate. The utility model has the advantages of excellent water repellency, spraying, roller coating to the substrate, or even counterproductive,penetration depth is greater than the emulsion type waterproof agent, emulsion and bulksolvent type three categories, and then penetrate into pores. Emulsion type organic silicon waterproof agent is using polysiloxane containing functional groups such ashydroxyl silicone oil silicone waterproofing agent from the solvent used in water soluble
