The main purpose:
Metal and other materials Surface treatment:
(1) Wear-resistant coating: the cutters, molds and other requirements of wear-resistant tool surface treatment, can improve wear resistance, increase service life.
(2) Absorbing stealth coating: nano-SiC in the 2-18GHz frequency band has a strong absorption capacity, while the radar operating rate of 1-15GHz, the nano-SiC used in military such as fighters, bombers and other shell materials made Coating, can be a good absorption of radar waves, play a stealth effect.
Modified high strength nylon alloy new material: in the nylon by adding β-SiC, the tensile strength than ordinary PA6 increased by 10% or more, wear resistance increased by 2.5 times.
Manufacture of precision structural ceramic devices: such as metallurgical, chemical, mechanical, aerospace and energy industries such as the use of sliding bearings, liquid fuel nozzles, crucibles, high-power high-frequency molds, semiconductor components.
Preparation of high-performance composite materials: the preparation of metal, ceramic-based, polymer-based composite materials.
(1) Ceramic-based composite materials: SiC composite ceramics with high strength, thermal conductivity, good shock resistance, oxidation resistance, wear resistance, erosion resistance and other excellent high temperature performance, a high-quality ceramic material. In metallurgy, energy, chemical and other industries are widely used.
(2) Metal matrix composites: SiC is an effective reinforced phase. When the mass percentage of SiC is 1%, the strength effect is good and the tensile strength is up to 391MPa.
(3) Polymer-based composites: The wear resistance of nano-SiC-filled polymer composites is nearly 4 times higher than that of unmodified resin, the friction coefficient is reduced by 36%, the tensile modulus is increased by 44.9% Tensile strength increased by 15.8%.
Modified special engineering plastic polyether ether ketone (PEEK) wear resistance: surface treatment with a coupling agent of nano-silicon carbide, the addition of about 5‰~1%, can greatly improve and improve the wear resistance of PEEK.
Composite nickel and other metal surface:
(1) Metal plating: nickel as the matrix metal, adding SiC particles on the metal plating plating, the composite coating significantly increased hardness, wear resistance increased 3-5 times, so that life increased 2-4 times, coating and the matrix of the combined force to improve 30-40%, strong coverage, uniform coating, smooth, delicate.
(2) Plastic plating: the hardness of the coating is 2.68 times the pure nickel layer, wear-resistant layer of pure nickel layer of 4.1 times, coating adhesion is good, does not appear blistering, cracks, shedding phenomenon.
In the application of rubber tires: add a certain amount of nano-silicon carbide does not change the original rubber formulations for modification, without reducing its original performance and quality under the premise of its wear resistance can be increased by 15% -30%. In addition nm silicon carbide used in rubber roller, printer film and other wear-resistant, heat, temperature and other rubber products.
Silicon carbide for special plastics: PI (polyimide), PEEK (polyether ether ketone), PTFE (polytetrafluoroethylene) and other special plastics, will be large-scale application of PE, PVC, PA, PP, PC, PET, PBT, ABS, POM, PPO, PPS and other fields, comprehensively improve the plastic wear, thermal conductivity, insulation, tensile impact, high temperature, reduce the thermal expansion coefficient performance.
Relay: the use of composite plating in the copper alloy or other metal matrix on the substrate to form a thin layer of Au-SiC composite performance excellent composite coating, used in the relay contacts, the reliability of the relay can work and greatly improve the service life.
Lubricants in the application: nano-silicon carbide in the various types of grease and quickly integrated with it, can form a nano-protective film on the metal surface, can greatly reduce the friction, so that the friction coefficient is almost close to zero, to play its Magical function. In addition, this material can also wear the metal surface of the physical nano-plating, thereby repairing wear.
Other areas: high-performance structural ceramics (such as rockets, nozzles, nuclear industry, etc.), absorbing materials, anti-wear lubricants, high-performance brake pads, high hardness wear-resistant powder coatings, reinforced ceramic toughening and so on.
This product should be stored in a cool, dry room, and avoid stress. The powder without the treatment of surface should not be exposed to the air during the use, to aviod absorb moisture agglomeration, affect the dispersion performance and the use of results.
