The concept and performance of penetrant (JFC) and precautions during use
The full name of penetrant (JFC) is a fatty alcohol polyoxyethylene ether, which is a nonionic surfactant. As the name suggests, penetrants are osmotic, and are substances that have a fixed hydrophilic and lipophilic group, can be aligned on the surface of the solution, and can significantly reduce the surface tension. The broad concept of penetrant refers to a class of chemicals that can help substances that need to penetrate into the substance that needs to be infiltrated. Industrially, surfactants are used (which can be anionic or non-exposed to the product with excellent adhesion, penetration). Extremely strong liquid material, fast drying, strong abrasion resistance, and good chemical and water resistance. The product is effectively infiltrated and reacts with components in concrete and stone to cure the components of concrete. It becomes a solid body and blocks the pores of various sizes of concrete to obtain a dust-free and dense whole, which improves the wear resistance, pressure resistance, compactness and impermeability of concrete. It can meet various needs of use. It is suitable for the treatment of cement floors such as factories, warehouses, docks, parking lots, etc., and the color can be adjusted without restrictions. Sub) or organic or inorganic solvents.
Special attention: porous or dry ground, where the concrete seal curing agent should be kept moist, when the surface is glued. It is better to be smooth, immediately sprinkle a small amount of water with a brush, or the machine brush surface concrete seal curing agent penetrates into the inner layer. Hold for 5~10 minutes until the concrete seal curing agent becomes gelatinous again, becomes smooth, and then thoroughly cleaned. If the surface has smooth residue, it means it is not cleaned, further cleaning, if not thoroughly Clean the residual concrete seal curing agent without residue, the white surface of the cement will appear white, immediately clean the unreacted residual material, or polish the ground with water.
