Air-entraining agent, also known as air-entraining agent, is a hydrophobic surfactant. It is dissolved in water and added to the concrete mixture, which can generate a large number of tiny air bubbles during the stirring process. Air-entraining agents can improve

Cement retarder is a kind of retarder that can delay the hydration reaction of cement, thereby prolonging the setting time of concrete, making fresh concrete maintain plasticity for a long time, facilitating pouring, improving construction efficiency, and at the same

1. High water reduction type: (1) Ultra-high water reduction rate, the water reduction rate can reach 40%; (2) The enhancement effect is obvious, the 3d compressive strength can be increased by 150%-200%, and the 28d compressive strength can be increased

VAM is a vinyl acetate monomer. It is a mass-produced industrial chemical that is used to make other industrial chemicals. VAM is an important intermediate in the manufacture of various polymers and resins used in adhesives, paints, coatings, films, textiles

VAE is a water-soluble white or off-white flowable powder, a copolymer of ethylene and vinyl acetate, with polyvinyl alcohol as a protective colloid. It has extremely outstanding waterproof performance, good bonding strength, increases the elasticity of the mortar and has

PVA fiber for concrete (or mortar) is an ideal environment-friendly cement reinforcement material, because of its unique molecular structure, it has good affinity with cement, and has good alkali resistance and weather resistance. Adding PVA fibers to cement concrete (or

In the paper industry, it is also widely used, because it can not only improve the wear resistance, folding resistance and tear resistance of paper, but also improve gloss, smoothness and printing adaptability. When used in construction glue, it can

Polymerization of vinyl chloride and vinylidene: As a suspension stabilizer and dispersant during polymerization, it can be used together with vinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control particle shape and particle distribution. Adhesive: As the adhesive of wallpaper, it

Hypromellose is a part of methyl and part of polyhydroxypropyl ether of cellulose. It can be dissolved in cold water to form a solution with a certain viscosity, and its properties are close to the viscoelastic substances (mainly mucin) in

Hydroxypropyl methylcellulose can be mixed with water-soluble polymer compounds to form a homogeneous, higher-viscosity solution. Such as polyvinyl alcohol, starch ether, vegetable gum, etc. The adhesion of hydroxypropyl methyl cellulose to mortar construction is higher than that of methyl cellulose.
