Zirconia beads are mainly used for ultrafine grinding and dispersion of high-viscosity, high-hardness materials, and can achieve zero pollution.
Advantages of Shanghai Zhimo zirconia beads for paint grinding
Zirconium beads are high-strength, inert, hard, perfect and fine spherical particles. Application in coatings can reduce costs, increase solid content, provide performance and improve process operating conditions.
1. Reduce viscosity and increase fluidity: Compared with other irregular-shaped fillers, zirconium balls roll as easily as steel balls between bearings. Zirconium beads have a large specific gravity, are easy to roll, and have large kinetic energy, so the viscosity of the formulation is reduced, the flow is increased, and the sprayability is improved.
2. Higher filling volume and lower cost: Compared with other shapes of fillers, zirconium beads have the smallest surface area to volume ratio. It can reduce the amount of resin and increase the amount of fillers, and the smaller-volume microspheres fill the gaps between the larger-volume microspheres, which increases the solid content, reduces VOC, and reduces costs.
3. Hard and wear-resistant: Zirconium beads have high hardness and wear-resistant, making the final paint surface hard and scratch-resistant. The surface lasts like a new one, saving you the cost and time of maintenance and repainting. If you use traditional fillers, soft or irregular particles will quickly wear or crack the surface.
4. Gloss control: Many gloss control materials will increase viscosity. However, the use of zirconium beads can significantly reduce the gloss without increasing the viscosity.
5. Effective barrier: compactly packed, hard, wear-resistant, and inert particles make the formula very durable and low in permeability, forming an effective barrier against harsh weather and chemical corrosion.
6. Stability: Because its composition is inert ceramic, the zirconium beads can resist the erosion of various chemicals.
7. Radiation curing: Zirconium beads are transparent to ultraviolet rays below 25nm. UV energy can penetrate the entire coating, which can help the deep curing of UV-curable coatings and improve construction efficiency. For the application of electron beam curing coatings, zirconium beads can increase viscosity and control flow.
8. Small equipment wear: Due to the high compressive strength, zirconium beads are best added during production and grinding. To improve the dispersion effect, sand milling, ball milling, and rolling are all possible. Compared with the use of other fillers of the same or lower hardness, the use of zirconium beads has less wear on the equipment.
