How Explosion-Proof Luminaires Work Principles of Explosion Proof Luminaires Explosions are substances that change from one state, through physical or chemical changes, to another state, and give off tremendous energy. The energy released at a rapid rate will subject the surrounding objects to violent impact and destruction.

Three conditions that an explosion must possess 1. Explosive substances: substances that react with oxygen (air), including gases, liquids, and solids. (gas: hydrogen, acetylene, methane, etc.; liquid: alcohol, gasoline; solids: dust, fiber dust, etc.)

2, oxygen: air.

3, ignition sources: including open flames, electrical sparks, mechanical sparks, static sparks, high temperature, chemical reactions, light energy and so on.

Why Explosion-proof Explosives: Many production sites produce certain flammable substances. About two-thirds of the sites in the coal mines contain explosive substances; in the chemical industry, more than 80% of the production workshops contain explosive substances. Oxygen: The oxygen in the air is ubiquitous. Ignition source: In the production process, a large number of electrical instruments are used, all kinds of friction sparks, mechanical wear sparks, static sparks, high temperature and so on are inevitable, especially when instrumentation and electrical faults occur. Objectively, many industrial sites meet the explosion conditions. When the mixed concentration of explosive substances and oxygen is within the explosion limit, an explosion will occur if there is an explosion source. Therefore, it is necessary to adopt explosion protection.

1, explosion-proof: according to the highest level of explosion-proof design and manufacturing;

2. Components: High-power LEDs, battery packs, housing materials, chargers, etc. are all supplied by the same supplier of well-known domestic manufacturers;

3, appearance: slightly different from other domestic manufacturers of similar products;

4. Function: more user-friendly and convenient switch operation, other similar products with other manufacturers;

5, performance: to reach the international high-end level, are higher than the market similar products.

Safe explosion-proof: This product is designed according to the requirements of GB3836.1-2000 and 3836.2-2000 completely. The explosion-proof type has the highest explosion-proof rating and is produced in full accordance with the national explosion-proof standard. It can work safely in various flammable and explosive places.

Explosion-proof lighting features 1, high efficiency and energy saving: use 4 3W high power white LED light source in series, high light efficiency, low energy consumption, long life of up to 100,000 h, cold light, reflective cup using high-tech surface treatment process , High reflective efficiency, uniform light color, lamp irradiation distance up to 1500 meters.

2, reliable and practical: special nickel-metal hydride battery pack no memory, no pollution, high capacity, long life, safe and stable performance, low self-discharge rate, a charge of light can work continuously for about 6h, working light can work continuously for more than 10h, in On the basis of the lighting function, the frequency flash function is also added and can be used for signal indication.

3, convenient and flexible: the outer surface of the anodized, light and beautiful shape, carrying handheld, shoulder two ways, touch switch, simple and convenient operation.

4, durable: imported high hardness alloy shell can withstand strong collision and impact, good sealing performance.

5, professional intelligence: charger using a dedicated charge management chip control, high reliability, fast charging, overcharge protection, short circuit protection, trickle charge, status indication.

Flattened Expanded Metal

Variety: small, medium and heavy Expanded Metal Mesh. Expanded aluminum mesh, expanded platinum filtration mesh, expanded brass mesh, expanded copper mesh, expanded stainless steel mesh, expanded nickel mesh. Opening in the shape of diamond, hexagonal or special shape. 
Use: Used with concrete in buildings and construction, maintenance of equipments, making of arts and crafts, covering screen for first class sound case. Also fencing for super highway, studio, highway. Heavy expanded metal can be used as step mesh of oil tanks, working platform, corridor and walking road for heavy model equipment, boiler, petroleum and mine well, automobile vehicles, big ships. Also serve as reinforcing bar in construction, railway and bridges.
