Nano-manufacturer TRUNNANO (aka. Luoyang Tongrun Nano Technology Co. Ltd.), after years of exploration of Nano-powders and accumulation of sales experience, summarized the specific applications of Nano-silica as follows:
Nano-silica is light-transmissive and has a small particle size, which can make plastics denser. After adding silica to the polystyrene plastic film, not only its transparency, strength, and toughness are improved, but the waterproof performance and anti-aging performance are also significantly improved.
Rubber is an elastomer with excellent stretchability, but its comprehensive performance is not satisfactory. It is usually necessary to add carbon black to the rubber in the process of producing rubber products to improve the strength, wear resistance, and aging resistance. However, due to carbon, The addition of black makes the products all black, and the grade is not high. The advent of nano-SiO2 in China has laid a material foundation for the production of a new generation of rubber products with novel colors and excellent performance.
After adding a small amount of nano-SiO2 to ordinary rubber, its abrasion resistance, tensile strength, flexural resistance, and aging resistance are all improved significantly, and the color is bright and the color retention effect is excellent.
Although organic dyes have bright colors and strong tinting power, their general light resistance, heat resistance, solvent resistance, and migration resistance are often inferior to inorganic pigments. The surface modification treatment of organic dyes by adding nano-SiO2 not only greatly improves the anti-aging performance but also improves the brightness, hue, and saturation to a certain extent.
Using nano-SiO2 instead of traditional Nano-additives added to ceramics can not only play the role of Nano-particles but also the second-phase particles, which not only improves the strength and toughness of the ceramic material but also improves the hardness and elastic modulus of the material. The performance and effect are more ideal than traditional Nano
The use of nano-SiO2 to composite the ceramic substrate not only improves the density, toughness, and smoothness of the substrate but also greatly reduces the sintering temperature. In addition, the application effect of nano-SiO2 in ceramic products such as ceramic filters and corundum balls is also very significant.
Sealant Adhesive
Sealants and adhesives are important products with a large quantity, a wide range, and a wide range of applications. It requires the best conditions for product viscosity, fluidity, and curing speed. Foreign products in this field have begun to use Nano-materials as modifiers, and nano-SiO2 is the preferred material. It is mainly coated with a layer of organic material on the surface of nano-SiO2 to make it hydrophobic and add it to the sealant. A silica structure is quickly formed, that is, the small Nano-SiOX particles form a network structure to inhibit the flow of colloids, accelerate the curing speed, and improve the bonding effect. Due to the small size of the nano-SiO2 particles, the sealing and impermeability of the product are also increased.
Glass Product
Although FRP products have the advantages of being lightweight, high strength, and corrosion resistance, they have low hardness and poor wear resistance. Scientists add nano-SiO2 to the gel coat resin by ultrasonic dispersion method, and perform performance comparison experiments with the gel coat without nano-SiO2, and found that its Mohs hardness has increased from the original 2.2 (equivalent to the hardness of plaster) to 2.8~2.9 Grade 3 (level 3 is the hardness of natural marble), the wear resistance is increased by 1 to 2 times. Because the Nanoparticles and organic polymers have grafting and bonding, the toughness of the material is increased, so the tensile strength and impact strength are increased by 1 time. As mentioned above, the heat resistance is also greatly improved.
