How to choose zirconium beads for abrasive paint coatings?
The grinding fineness of the coating cannot blindly pursue the finer the better, because the fineness of the product will also directly affect the covering power, film adhesion and durability of the coating. Equipped with properly ground zirconium beads.
All in all, there are many factors that affect the grinding effect. Generally, specific problems will be analyzed in detail, and suitable grinding zirconium beads will be recommended according to the actual needs of customers.
Manufacturers in the coatings industry commonly use three-roll mills, horizontal mills, vertical mills and basket mills. These types of grinding equipment are also mostly used for the grinding and manufacturing of medium and high viscosity liquid raw materials such as paints, inks, pigments and resins. Each of these grinders has advantages and disadvantages.
The operation of the grinding machine will drive the grinding zirconium beads to run at a high speed in the cavity, so that the coating material is pressurized in the narrow grinding zirconium bead gap and then rotates and strikes at high speed, resulting in submerged functions such as mixing, emulsification, dispersion, rubbing and rolling. According to the production requirements, the fineness of the raw materials can meet the corresponding standards and requirements.
Is the size of the ground zirconium beads as small as possible?
Usually, the number of small-sized grinding zirconium beads in the same proportion of grinding equipment will be more, which will generate more collision sites in the grinding machine cavity, and then generate more stress energy, resulting in more effective grinding. Generally speaking, reducing the particle size of the ground zirconium beads can improve the grinding efficiency to a certain extent. However, grinding zirconium beads is not as small as possible. For specific materials, there will be an optimal solution for the size of the ground zirconium beads. Be sure to match the grinding zirconium beads of suitable size according to the characteristics and requirements of the material.
What standard can be used to measure good ground zirconium beads?
Many application fields including the coating industry, such as medicine, cosmetics, and agrochemicals, actually have similar requirements for grinding zirconium beads, such as: accurate composition ratio, large specific gravity, high grinding efficiency and low wear of grinding zirconium beads , good stability, while ensuring low crushing rate. The higher the strength and toughness of the ground zirconium beads, the less likely they are to break. The ingredients must also be guaranteed.
