Foundry Silica Particles

Description

Foundry Silica Particles are one of the extremely important high-tech ultrafine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, electrical resistance, and other specific properties,. With its superior stability, reinforcement, thickening and Thixotropy, this product has unique characteristics in many disciplines and fields and plays an irreplaceable role. These particles are widely used in various industries as additives, catalyst carriers, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, metal soft polishing agents, insulation and insulation fillers, advanced daily cosmetics fillers, spraying materials, etc. These silica particles also provide a new material foundation and technical guarantee for the development of related industrial fields. Due to their unique functions in magnetism, catalysis, light absorption, thermal resistance, and melting point compared to conventional materials, they have received great attention from people.

Advantage

Foundry Silica Particles contain a large number of hydroxyl groups on their surface, which can react with many substances to form amino, carboxyl, thio, and other functional groups. Silicon dioxide particles can also adsorb antibiotic proteins, which is easy to surface modify, making it widely used in biological analysis. In addition, silica itself is non-toxic and has high biological affinity, so it is increasingly valued in the field of biochemical testing.

Features

1. High fluorescence intensity;

2. High stability;

3. Beneficial for surface modification;

4. Uniformity and controllability of particle size;

5. Most fluorescent reagents have some toxic and side effects on living cells, which can be avoided by wrapping them with silica particles.

The above characteristics make Foundry Silica Particles have great development prospects in immune detection and biosensors.

Application

1: Ceramic field

The drawbacks of modern oxide ceramic products are high brittleness and low smoothness. Adding silica nanoparticles to ceramics can greatly reduce the brittleness of ceramic products and improve their toughness.

2: Rubber field

Traditional rubber products improve strength, wear resistance and aging resistance by adding carbon black, with single color. Adding silica nanoparticles to rubber and utilizing their excellent optical properties can prepare rubber products with novel colors and excellent performance.

3: Coatings field

Due to the ultraviolet radiation resistance of silica nanoparticles, their stability, weather resistance and Thixotropy can be improved by adding them to the paint. In addition, it can also improve the adhesion between the coating and the wall.

4: Textile industry

Silica nanoparticles have a broad application prospect in the textile field, mainly because of its anti-aging, anti ultraviolet, sterilization and deodorization functions. The addition of functional fiber in the preparation can improve the anti ultraviolet radiation ability of the product and have the effect of purifying the air.

5: Cosmetics field

These particles have strong chemical stability and are not easily decomposed under ultraviolet light irradiation, meeting the requirements of cosmetics and sunscreen products for shielding against sunlight ultraviolet rays. Moreover, the color of the particles is white, so adding them to cosmetics not only achieves sunscreen effect but also whitening effect.
