Applications:
Coating: on the basis of the original formula of water-based latex paint, nanometer silicon oxide added totalweight 0.3-1% (to be fully dispersed), the suspension stability, thixotropy, bond strength between the coating and substrate, smoothness properties were improved significantly, shorten drying time, artificial acceleratedultraviolet aging test time multiplied, scrub resistance by the thousands to tens of thousands of times, and anti fouling coating is improved obviously.
Plastic: silica nanoparticles fully dispersed in thepolypropylene (PP), polyvinyl chloride (PVC) and other plastic raw materials, can greatly improve the strength,toughness and plastic products, wear resistance and aging resistance. Such as the modification of nano PP, the main performance index of the water absorption, insulation resistance, compression residual deformation, flexural strength of all reached or exceeded the engineering plasticnylon 6, product durability increased more than one times,can replace the nylon 6 and in some areas.
Color rubber: add a small amount of silica nanoparticles insolution polymerized styrene butadiene rubber (instead of black) as reinforcing agent and anti-aging agent, color rubber products produced the toughness, strength,elongation, bending resistance and anti ageing properties have reached or exceeded three yuan of ethylene propylene rubber.
Magnetic materials: in iron coke powder is added in thecomposite powder with nano silica based modified, after testing, the highest level of main performance products tothe United States the existing similar products, such asremanence intensity greater than 4100 Gs, intrinsic coercivity is greater than 3000 Oe, the energy product is greater than 4 mGOe, and at the same time, material production significantly reduce costs.
In addition, the nano silica can be widely used in ceramic(porcelain enamel), gypsum, batteries, paints, adhesives,cosmetics, glass steel, chemical fiber, organic glass,environmental protection and other areas of productupgrading.
Product name
White carbon black SiO2
Product description
One, due to a series of advantages of white carbon black products, it can be widely used in many fields.
Rubber products
White carbon black is used in color rubber products to replace carbon black, to meet the needs of white or semi-transparent products.
Of white carbon black and it has strong adhesion strength, tear resistance and heat-resistant anti-aging performance, so can replace part of the carbon black in the black rubber products, in order to obtain high quality rubber products, such as off-road tires, otr tires, radial tire, etc.
Agricultural chemicals
In the agricultural chemicals, such as pesticide and efficient spraying fertilizer, using silica as carrier or diluent, can maintain lasting effect, because it has high adsorption capacity, easy suspension, good affinity and chemical stability.
It can remain unchanged for a long time even under rain, wash and heat.
Daily chemical products using silica as filler and abrasive paste transparent color and opacity of toothpaste, this kind of toothpaste has good flexibility, dispersion, paste is smooth, soft, good abrasion resistance, abrasion toothpaste tube body;
It keeps the toothpaste stable.
In particular, it has good compatibility with nitrogen, and it can avoid the disadvantages of calcium salt.
Cementing agent is used in the adhesive of natural rubber or synthetic rubber, which provides the thixotropy and reinforcing property. Meanwhile, due to its extensibility, it can improve adhesion and high quality and low price.
Anti caking agent
White carbon black can be used in a number of products to enhance the free liquidity, such as lawn fertilizer, fungicides, grinding wheel abrasive, laundry bleach, phenolic molding methenamine, phenol and urea sulfur manufacturing plastic products, rubber and anti caking mixture.
Paper packing
Using white carbon black as paper filler can improve the paper anti-ink through performance and mechanical strength, increase whiteness, reduce unit weight.
It can effectively realize the paper weight, reduce production cost and improve the performance of paper.
In addition, it can be used in many industries, such as fire extinguishing agent, feed, cosmetics, anti-gloss agent, pigment, paint and so on.
Second, white carbon black is white powder X-ray amorphous silicate and the floorboard of the silicate products, mainly refers to precipitated silica, silica, ultrafine silica gel and gel, also including aluminum silicate and calcium silicate powder synthesis and so on.
1. White carbon black is used in color rubber products to replace carbon black, which can meet the needs of white or semi-transparent products.
2. In agricultural chemicals, such as pesticides, high efficiency spraying fertilizer, etc., use white carbon black as the carrier or diluent, which can maintain lasting effect.
3. Transparent color and opaque toothpaste with white carbon black as fillers and abrasives, with good flexibility and dispersibility, the paste is soft, abrasion is good, and the toothpaste tube body is not worn.
It keeps the toothpaste stable.
4. Thixotropic and reinforcing properties are provided in the adhesive made of natural rubber or synthetic rubber.
5. Using white carbon black as paper filler can improve the paper’s anti-ink performance and mechanical strength, increase the whiteness, and reduce the unit weight.
Appearance
white powder
Usage
1.Used as ultraviolet absorbent for plastic film.
2.Used as chemical reagent, also used in organic synthesis.
3.Mainly used in the production of new bleaching agent, disinfectant, water treatment agent and resin, paint and metal cyanide corrosion inhibitor, etc.
