Sodium polyacrylate is a commonly used dispersant, also known as sodium polyacrylate suspension agent. It has the following characteristics and applications:
Dispersant characteristics: Sodium polyacrylate is an anionic surfactant with good dispersibility and stability. It can form a high molecular weight polymer structure in water, improve the dispersion of particles, and avoid particle sedimentation, aggregation, or accumulation.
Dispersion effect: Sodium polyacrylate dispersant can disperse solid particles in water, making them evenly distributed and maintaining a stable suspended state. It can effectively disperse various particles, such as mineral powders, dye pigments, nanomaterials, etc., ensuring that they do not aggregate to form clumps or precipitates.
Stability improvement: Sodium polyacrylate can improve the stability of suspensions through charge repulsion and steric hindrance effects. It adsorbs on the surface of solid particles and forms a cloud environment with negative charges, causing electrostatic repulsion between particles and preventing mutual attraction and condensation between them.
Application field: Sodium polyacrylate dispersant is widely used in various industries, such as coatings, inks, pigments, ceramics, textiles, building materials, etc. It can improve the fluidity of the product, increase the dispersion of pigments, and improve the glossiness and precipitation resistance of the coating. In addition, it is often used in the textile dyeing process to maintain the uniform dispersion and fixation performance of the dye.
It should be noted that when using sodium polyacrylate dispersant, specific application requirements and instructions should be followed to obtain the best dispersion effect and stability.
