What is water-reducing agent? Water-reducing agent, its molecular formula is composed of the hydrophilic and hydrophobic groups. When the cement is mixed with water, there is no water-saving technology. Due to the role of molecular cohesion between the cement particles, the cement will form a storage structure, and part of the river water will be wrapped in the flocculation structure of the cement particles to reduce the fluidity of the concrete mixture, fall into the cement slurry, and add water-reducing agent. The surface of the cement particles has the same electric charge on the surface of the particles, thus releasing the Uri water in the flocculation structure. In addition, the water-reducing agent can also form a layer of a solvated water mill on the surface of the cement particles.
Water reducer - melamine series water reducer It is the product of melamine sulfonated by sulfuric acid and then condensed with formaldehyde, so its chemical name is sulfonated melamine formaldehyde resin, which belongs to an anionic surfactant. This kind of water reducer is a white powder in appearance, soluble in water, has good dispersion of powder materials, high water reduction rate, and good fluidity and self-repair.
Preparation method of water-reducing agent-melamine series water-reducing agent The synthesis principle of the ASM melamine series superplasticizer is to make formaldehyde and melamine form carbon-positive particles in an alkaline medium and then condense in an acidic medium to connect the long-chain structure. At the same time, it provides amino sulfonic acid to make the molecular structure contain a certain amount of polar sulfonic acid radical, which increases the content. Because the chemical properties of the substances involved in the reaction are relatively active, the reaction temperature, reaction speed, and the proportion of reactants significantly impact the product's performance; the reaction temperature and speed are the keys to finding the appropriate reactant ratio. The composition ratio is melamine: formaldehyde: amino sulfonic acid=1: (3.5-4. O): (2-2.5). The reaction temperature is controlled at 75-80 ℃ in the first stage and 45-60 ℃ in the second stage; The reaction time is controlled within 1.5-3 h, the product performance is excellent, and the production cost is the lowest. In the production process, a series reaction of one kettle is realized by adding a reflux device, which simplifies the production process and eliminates the generation of "three wastes."
Price of water-reducing agent Water-reducing agent particle size and purity will affect the product's price, and the purchase volume can also affect the cost of the water-reducing agent. A large amount of large amount will be lower. The price of the water-reducing agent can be found on our company's official website.
