Professional Custom Lamp Holder Accessories Manufacturer

Thermal spray technique is the inner surface of lamp holders manufacturing engineering part, which is a surface-strengthening and surface modification techniques, by the metal surface coating layer coating the metal base with a wear, corrosion, high temperature oxidation, electrical insulation, thermal insulation, radiation protection, less wear and sealing performance. Thermal spray technology is mainly used for high temperature, wear-resistant, corrosion resistance and other parts of the pre-protection, the preparation of the functional coating and repair of the failed components.
Wider application in the thermal spray process for flame spraying, arc spraying, plasma spraying, detonation spraying and supersonic spraying technology. Flame spraying is achieved through the flame spray gun, the spray gun through the valve after the introduction of acetylene, oxygen or compressed air, acetylene and oxygen mixture at the nozzle outlet to produce combustion flame, introducing a powdery or rod-like coating material is heated and melted in the flame forming a mist of small droplets, the effect of the flame stream is injected into the surface of the substrate form a coating. The arc spraying two linear material coating material used by the wire feed wheel automatically imported by large current arcing between the two linear material, linear rapid melting materials under high temperature of the arc by compression The action of air into small droplets to be ejected onto the surface of the substrate to form a coating. Such as plasma spraying suitable for powder coating materials, a plasma gun, the electrical energy into heat energy, generating a plasma flame of high temperature and high flow, the flow temperature plasma flame can be as high as 50,000 ° C, all the spraying material can melt. Explosion spraying is the use of combustible gas and oxygen mixture ignition provides the energy of the explosion, the powder is sprayed onto the surface of the substrate to form a coating. The supersonic flame spraying methods due to the high particle impact velocity, so that the bonding strength, hardness, dense, abrasion resistance have been improved.
Most porcelain lamp holders having a structure of an ionic bond or a covalent bond, high bond energy between atoms with strong, the surface free energy is low, thereby imparting a high melting point of the ceramic material, high stiffness, high chemical stability, high dielectric insulation capacity, thermal expansion coefficient is small, and a small coefficient of friction characteristics; Poor compared with the metal material, the plastic deformation capacity and the sensitivity of stress concentration and cracks. Obviously, as a mechanical structure with a ceramic material, its reliability differential than the metal material, machining is difficult, the cost is high. However, the use of the thermal spraying technique, preparing a ceramic coating on a metal substrate, can the characteristics and the characteristics of the ceramic material of the metal material organically combined to obtain the composite material structure. This composite structure with exceptional performance, thermal spray technology applied to civilian industrial areas such as energy, transportation, metallurgy, textile, petrochemical, machinery quickly expanded from high tip.
The characteristics of the porcelain lamp holders coating technology compared with the overall structure of the ceramic material, ceramic coating technology has the following characteristics:
1. Organic metal material strength and toughness, ease of processing and high temperature, wear and corrosion resistance and other characteristics of the ceramic material combined.
Reasonable choice of coating materials and suitable for the spraying process, strengthen coating surface can get a variety of functions.
3 without the limitations of the substrate: a base material used for thermal spraying can be metal, ceramic, cement, refractory materials, stone, gypsum and other inorganic materials may also be organic materials such as plastics, rubber, wood, paper.
4 from the workpiece size restrictions and construction sites.
5. Faster coating deposition rate, controlled thickness, the process is simple. 6. Ceramic coating workability is good, and after spray coating damage.
