Winner particle size analyzer seizes the opportunity to land at 2023 China International Coatings Exhibition

At the end of February, spring returns to the earth and everything recovers. The China International Coatings Exhibition kicked off in Guangzhou after a year. Jinan Winner Particle Instrument Co., Ltd. participated in the exhibition with the winner802 nanoparticle size analyzer. China International Coatings Exhibition is the leader in global pigment and dye industry exhibitions, attracting well-known domestic and foreign pigment and dye companies to actively participate in the exhibition. While displaying and sharing products, it promotes exchanges and cooperation between industries, promotes the optimal allocation of resources, and builds domestic and foreign regional cooperation. bridge.

Coatings are widely used in daily life. They are mainly used for modification and protection when attached to the surface of objects. For example, fireproof and moisture-proof coatings are used in building materials; decorative protective coatings are used on the surfaces of automobile parts and daily necessities; they are used for insulation of electrical appliances, electronic components, etc.; they are used for decorative anti-corrosion of furniture, etc. Coatings are gradually becoming a multi-functional engineering material, and the market has also put forward higher demands for the functional properties of coatings.

The particle size distribution of paint particles has a great influence on the performance of the paint. First, it affects its charging performance. The adhesion force of paint particle spraying mainly comes from the Coulomb force of electrostatic charge. Generally speaking, the larger the particle size of the paint particles, the better the chargeability. , but the growth rate of the particle's gravity as the particle size increases is greater than the growth rate of the Coulomb force. That is to say, when the particle size reaches a certain level, the gravity will be much greater than the Coulomb force, resulting in poor powder loading rate and coating effect.

With the application and development of nanotechnology in the field of coatings, coatings are being updated. Nano coatings must meet two conditions: first, there is a phase with a size of 1~100nm; second, the performance of the coating is significantly improved due to the existence of the nanophase. or have new features. The improvement of nano-coating performance mainly includes: first, the improvement of construction performance. Using the influence of nanoparticle size on rheology, such as nano-SiO2 used in architectural coatings, can prevent the coating from sagging; second, improve weather resistance. Utilizing the absorption of ultraviolet rays by nanoparticles, such as nano-TiO2 and SiO2, weather-resistant building exterior wall coatings, automotive topcoats, etc. can be produced; third, the improvement of mechanical properties. The strong interfacial bonding force between nanoparticles and resin can be used to improve the strength, hardness, wear resistance, scratch resistance, etc. of the coating.

Winner802 Nanoparticle Size Analyzer is a particle size detection equipment specially for nanoparticles. It is the product of the National Science and Technology Innovation Fund Project for Small and Medium-sized Enterprises. -10000 nm, high sensitivity, anti-interference, quick test, can be equipped with dual-wavelength lasers (for colored nanoparticles, such as pigments, dyes and other particles with light-absorbing properties).

In the future, the WIinner  particle size analyzer will provide Chinese coating companies with more accurate particle detection technology and better serve customers through continuous innovation with a better attitude.
