Generally speaking, metal aircraft made of aluminum can be used safely for decades, because the metal aircraft's own electrical conductivity is enough to protect the aircraft from lightning strikes, with the development of science and technology, composite materials are widely used in aviation aircraft, when lightning strikes or lightning current flows through the composite structure, it will cause this composite structure embrittlement, delamination or fracture. And the most serious damage to the composite structural parts is usually the highest energy density of the lightning inflow point or out point.

Description

Product Description

Usually, the flame or the plasma sprayed aluminum, the LSP metal mesh are used for lightning strik protection on composite structures. Due to the advantages of light weight, good flexibility, good combination on a compound curvature surface as well as excellent lightning protection effect, LSP mesh has become the main method of lightning current protection for carbon fiber composite structural components. The higher the conductivity of the outer surface of the aircraft, the faster the lightning current spreads, the smaller the energy concentration phenomenon, the smaller the damage, the lightning protection metal mesh provides a safe conductive path on the external structure, so that most of the lightning current is retained on the outside and quickly exported.

KINSON’s micromesh can effectively and directly defend against catastrophic structural damage from lightning strikes, dangerous electric shocks to passengers and loss of aircraft flight control, in addition to providing EMI shielding and Hirf protection against electromagnetic fields in space to prevent aircraft communications and electronic equipment.

Appliance

Schematic diagram of three-level lightning protection zoning, metal mesh can be laid on the fuselage, wings, rudders, spoilers, vertical tail, ailerons, flaps, gap wings, and engine nacelles, etc.

The advantages of KINSON’s LSP meshes are：

1, high conductivity; can withdraw the strike of 200,000 amperes and repeated lightning strikes；

2, excellent shielding, conductivity, heat transfer performance;

3, both lightning and EMI interference characteristics;

4, light weight and flexible, with good ductility and drape;

5, sigle in one uinit structure. Different from the woven mesh, the expanded materials do not lose strand and ensures uncompromised conductivity；

6, Uniformity of opening and thickness, making the surface smooth and the adhesive easier to penetrate;

7, flexibly designed with different weights and thicknesses according to different structures to meet the requirements of installation;

8, helpful to reduce the cost of material, installation and maintenance.

Wind turbine blade lightning protection net

In the current wind power market, the composite materials, because of its unique performance advantages to become the mainstream of wind turbine blades, in order to achieve high-strength and lightweight. The traditional flashing system can not provide complete protection. In the cases of actual lightning damage, the lightning strike can bypass the flashing device and hit the blade, which is very common.

Battery

The electrically active material compromising the electrodes of most modern battery designs are powders and require a mechanical support structure to hold them in place during the manufacturing process. This support structure also functions as a current collector and provides the electrical connection point for the external circuit. In the battery production, the expanded metal foils are coated with active electrode material and then roll to cylinder, which is the main structure of battery core.

Electromagnetic Shielding

The screen net can not only shield electromagnetic radiation interference, but also transmit light, so it is the only available shielding material for observation and display holes. At present, it has been widely used in radar display, computer display terminal, printer, radio, spectrum meter, precision instrument and so on digital and image display window, electronic shelter and electromagnetic shielding of shielding room observation window.

The membrane support grids are made of nickel-plated steel and pure nickel, and in different modes as 3Dstructure, flattened and corrugated. The products are characterized by smooth surface, uniform thickness, high electric densitylow resistance, corrosion resistance, uniform and smooth fow field, low maintenance cost and so on, so they are widely used inlarge electrolvzers, KiNSON can produce the products accordina to the reauirements of material. hole. thickness, strand. modeand dimensions.Our team is professional in the electrolyzer units and spare parts, including end load bearing plates, end polar plates, middlepolar plates, bipolar plates, besides welding and electroplating services. We have mature technology and successful projects.

Industrial

Expanded metals, along with our other metal alternatives, is manufactured with no waste and is available in 2D and 3D appearances. It has exceptional corrosion, heat, and impact resistance. The unique properties of lower and higher alloyed grades provide resistance to corrosion in many different environments. Moreover, 2D and 3D appeared can expand the area and carry much more catalysts. The manufacturing process adds rigidity to the original material and the mesh can be annealed to improve its formability. Expanded metal mesh is a versatile and durable one-piece construction that is used for a wide range of applications. Industries we commonly serve include HVAC services, filtration, petrochemical, food service, automotive, acoustics, architecture and more.
