Microsilica It is very common. The raw iron ore is obtained by crushing, water cleaning, scrubbing, extremely fine, and grading. The use of silicon micro powder is very common. Its sphericity is improved, the touch is fine, the loose adhesion is good, and the oil absorption rate is low, which makes it widely used in many fields, such as building coatings, electronic devices, and chemical plants, In the production and processing of silicon powder, we need to pay attention to that the production and processing methods are different, the prices are different, and the regions used are also different
1. Application of silicon powder in plastic products Active silicon powder is added to rubber, cis-1,4-polybutadiene rubber and other rubbers. The powder equipment is easy to loosen, the professional skills of rubber mixing are good, and the injection and extrusion properties are good. It can also develop the vulcanization rate of vulcanizates, and it can also improve the viscosity of plastics. In particular, ultra-fine silicon powder can replace some white carbon black added to rubber, The development of physical property index values of finished products and the reduction of product costs have good practical effects.
1. The actual effect of 2 μ m silicon micro powder up to 60-70% is very high when it is used for the entrance and exit medical isopropyl titanate butyl bottle cap and the insulating rubber boots of electric welders. Silicon micropowder is used as filler in the production and manufacturing of imitation leather products, and the compressive strength, elongation, softness and other professional skill indicators of the finished product are better than those of the products manufactured with inorganic materials such as active calcium carbonate, active calcium bicarbonate, and active pyrophyllite as filler.
Silicon micropowder is used in the battery rubber shell instead of clay, active calcium carbonate and other powder equipment materials, with the charging amount up to 65% and superior professional skills. The finished rubber shell has smooth and moist surface, high strength, acid corrosion resistance, working voltage resistance, thermal deformation, impact resistance and other physical and mechanical equipment functions that reach or exceed the JB3076-82 professional skill index value.
2. Application of silicon powder in plastic products active silicon powder is an ideal synergist for polypropylene, polyethylene, high-pressure polyethylene and other products. It can be made into masterbatch and used in polyethylene floor tiles to improve the wear resistance of products. Silicon micropowder is used for alkane epoxy resin plastic film. Its powder equipment is loose and uniform, with good film coating performance and strong structural mechanics function. Compared with the plastic packaging film produced with PCC as filler, the infrared induction transmittance of the barrier is reduced by more than 10%, which is extremely beneficial to the application of agricultural machinery shed film. It can also be used in areas where the outer sheath of cables and wires is too long.
3. Application of silicon powder in laminated glass and glass fiber for melting instruments and equipment Due to the small particles and high purity of silicon powder, it is easy to melt in glass production and manufacturing, and the time is short. The physical and chemical functions and appearance quality of finished products such as borosilicate instrument and equipment laminated glass, sodium calcium instrument and equipment laminated glass, and neutral container laminated glass have reached the corresponding standards, In addition, the actual effect of energy conservation in production and manufacturing is very significant.
Moreover, according to the characteristics of fine and uniform particle size distribution and large specific surface area of silica powder, it is used for immediate metal drawing of glass fiber, developing the homogenization level of glass fiber collaborative material and accelerating the vitrification rate in the furnace. The reliability of metal wire drawing is better than the professional skills of glass bead metal wire drawing, and has a significant practical effect of energy conservation, environmental protection and product cost reduction. As a mineral material for environmental protection and energy conservation, silica micropowder is used in porcelain posts, and ideal practical effects have also been achieved in reducing the firing environment temperature and developing the yield.
4. The effect of polishing and brushing wear-resistant materials with silicon powder is very good. Follow the progress of intelligent professional skills, and the surface solution of materials is also required to be higher and more precise. The application of wear-resistant materials is becoming increasingly common. Because its particles are close to the ring, the silicon micropowder is superfine crushed according to the extremely fine and grade classification, and then treated with modified materials. It is an excellent scrub wear-resistant material for metal products. If it is used in scrub rolling bearings, the smoothness can reach more than 3.0, better than similar imported products. Other products are used for polishing semiconductor material posts, fine gate valves, hard disks, magnetic tape drives, and cars.
