What is Naphthalene-based High-efficiency Water Reducer?

Naphthalene-based water reducer is a chemical additive widely used in the field of building materials. The main function of water reducer is to reduce the amount of cement in concrete or cement mortar, thereby improving its fluidity and plasticity.

As a type of water reducer, naphthalene-based water reducer has unique characteristics and advantages. This article will introduce in detail the definition, mechanism of action and application of naphthalene-based water reducer in building materials.

Definition of naphthalene-based water reducer

Naphthalene-based water reducer is an organic compound with a naphthalene ring structure in its chemical structure. This compound can interact with the surface of cement particles, improve the fluidity of cement and mortar, and reduce the viscosity of concrete. Naphthalene-based water reducer is usually a colorless or light yellow liquid, and its concentration and addition amount can be adjusted as needed.

Mechanism of action of naphthalene-based water reducer

  1. Naphthalene-based water reducer works in the following aspects:
    Dispersion: Naphthalene-based water reducer has excellent dispersibility, which can evenly disperse cement particles in water to prevent them from agglomerating and settling. This can improve the fluidity of concrete and improve construction efficiency.
  2. Adsorption: Naphthalene water reducers can form a protective film on the surface of cement particles to reduce water loss. This film has a certain elasticity, which can maintain the dispersion of cement particles and improve the plasticity of concrete.
  3. Water-reducing effect: Naphthalene water reducers can reduce the water-cement ratio of concrete, thereby reducing the viscosity of concrete and reducing the amount of cement. This is very important for improving the strength and durability of concrete.

Application of naphthalene water reducers in building materials

Naphthalene water reducers are widely used in building materials and can be used in the manufacturing process of various cement products and concrete components to improve their process performance and quality. The following are several common application areas:

  1. Ordinary concrete: Naphthalene water reducers can be added to ordinary concrete to improve its fluidity and plasticity, reduce the water-cement ratio, and improve the strength and durability of concrete. This is very important for the structural stability and service life of buildings.
  2. High-performance concrete: The application of naphthalene water reducers in high-performance concrete can make concrete have higher strength and better durability. It optimizes the performance of concrete by reducing the water-cement ratio and improving the fluidity of concrete.
  3. Cement products: Naphthalene water reducers are also widely used in the production of cement products, such as blocks, bricks, pipes, etc. It can improve the process performance and quality of cement products, reduce the occurrence of cracks and increase the density of products.
  4. Plaster mortar: Adding naphthalene water reducers to plaster mortar can improve its plasticity and construction performance, making the mortar easier to construct and level. At the same time, it can also improve the adhesion and durability of plaster mortar.

Bailin Group specialized in producing Sodium naphthalene sulfonate formaldehyde (Dispersant NNO), also called :FDN/SNF/MF . It ​​has excellent diffusivity and protective colloid properties, but no surface activity such as penetration and foaming. It has affinity for protein and polyamide fibers, but no affinity for cotton, linen and other fibers.

It is mainly used as a dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes, with excellent grinding effect, solubility and dispersibility; it can also be used as a dispersant in textile printing and dyeing, wettable pesticides, papermaking.

As an important building material additive, naphthalene water reducers have broad application prospects. By improving the fluidity and plasticity of concrete and reducing the water-cement ratio, it can improve the quality and performance of concrete and meet the needs of different projects.

However, when using naphthalene water reducers, it is necessary to reasonably determine the type and amount of additives according to specific construction conditions and requirements to give full play to its advantages. With the continuous innovation and development of building material technology, it is believed that naphthalene water reducers will have a wider application in the future.
