Nano silica

Nano-silica has the characteristics of small particle size, many micropores, large specific surface area, high surface hydroxyl content, and strong reflection ability of ultraviolet, visible light and infrared rays. Especially with the improvement of product surface treatment technology, the degree of soft agglomeration of nanoparticles has been significantly reduced, and they have good compatibility with organic polymer materials, which has greatly broadened the application fields of the product.

Product application
Based on the original formula of water-based latex paint, the coating is added with the total weight of nano-silica (which needs to be fully dispersed). Its suspension stability, thixotropy, bonding strength between coating and substrate, smoothness and other properties have been significantly improved, the drying time has been shortened, the artificially accelerated UV aging test time has doubled, and the washing resistance has been improved from thousands of times to above. Thousands of times, and the stain resistance of the coating is also significantly improved.
, Building waterproofing agent Nano-silica is used in building waterproofing agents. It can quickly penetrate into the interior of building materials, block capillary pores, form a three-dimensional network structure, and become a waterproof layer with excellent performance. It has excellent anti-aging and waterproof properties. Great improvement, thus making the building impervious to water seepage, mildew, moss, frost cracking, weathering resistance, etc., presenting a series of unique properties.
Adhesive Nano-silica is used in adhesives, which can greatly improve the bonding strength. The tensile strength and elongation were increased compared to those without nano-silica filler respectively. In the glue solution, the added nano-silica can increase the viscosity of the glue solution and also improve the bonding strength and initial tack of the adhesive.
Inkjet printing and photo paper coatings use nano-scale silica materials to form extremely fine inorganic-organic composite particles. After the ink is printed, it is immediately absorbed by the honeycomb-like micropores, and the coating absorbs the ink. The printing force is very strong, and it can also show a good layering effect for printing parts with very dark tones. It dries quickly. When you come out of the printer, you can directly touch it. The coating material is very delicate, not only has high brightness, but also can match high precision. photo printing. It has very good waterproof properties and can remain intact even if it is soaked in water for several hours. Its advantages are three high and one fast, namely high gloss, high waterproof, high ink absorption and quick drying.
Ceramics use nanometers to composite ceramic substrates, which not only improves the density, toughness and smoothness of the substrates, but also significantly reduces the sintering temperature. The main performance indicators reach or even exceed those produced by the United States, Japan and other countries.
In other aspects, adding nano-silica during the processing of vinyl fiber fabrics can change the properties of vinyl and play a matting effect. On audio and video tapes, nanosilica is used as an anti-sticking agent. In the light bulb industry, lining the inner wall of the light bulb with a nano-silica interference film can improve the luminous efficiency of the light bulb and extend the service life of the light bulb. Adding surface-treated nano-silica to organic glass can improve the material's UV radiation resistance and impact strength. In the battery industry, nanosilica is used as a separator. In the catalyst industry, nanosilica is used as a carrier. In addition, nanosilica can prepare thermal insulation materials with superior performance.
Dosage Recommended dosage, customers can conduct experiments to select the optimal dosage according to specific conditions.
