Explosion-proof electrical switches, as the name suggests, is able to be used in harsh, more dangerous explosive environments. For example: coal shrine "industry, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewage buried are required to use explosion-proof electrical switches . Currently, there are many brands and types of explosion-proof electrical switches on the market, but the real meaning , Its excellent explosion-proof performance, safe and reliable quality of explosion-proof electrical switches, the market is still relatively small.Among them, the British Bulgin brand is ideal.Bulgin explosion-proof electrical switches, explosion-proof electrical switches based on dangerous environment professional design, in line with ROHS certification, through a special embarrassed (test, suitable for a variety of harsh environments. From the security role.

Because the explosion-proof electrical switch needs to be applied to the coal industry, oil, electricity, metallurgy, railways, ships, aviation and other enterprises. Therefore, high wear and tear corrosion resistance and destructiveness are required. Bulgin explosion-proof electrical switches have these properties. Bulgin Explosion-proof electrical switch front and rear panel fixed switch in three shapes: convex, arc-shaped and horizontal. According to the needs of the human environment transformation, electronics and the natural environment, the switch function has a variety of options, and board installation can reach IP and IPE8 standards.

Optional copper, chrome-plated material where steel is not required. The recessed panel switch is now available to provide self-locking, on-off function. The illuminated switch can be either circular or circular, with a variety of colors to choose from. It is a new range and adds extra dimensions to control the board. Explosion-proof electrical switch is mainly used in a variety of needs of a safe, reliable, easy to break the connection application. Especially in the explosive gas may exist in the manufacturing plant equipment and system power supply occasions; also used in petroleum and other industrial sites.

In order to prevent rust on the explosion-proof surface, apply oil or 204-1 replacement anti-rust oil on the explosion-proof surface. The selection of explosion-proof electrical equipment : one to meet the dangerous areas of the danger zone to choose the appropriate type of electrical explosion; two according to the dangerous environment may be the existence of flammable gas / dust type to choose the level of explosion-proof electrical equipment and temperature groups ; Third, consider the impact of other environmental conditions on explosion-proof performance (for example: chemical corrosion, salt spray, high temperature and humidity, dust and rain, or vibration); Fourth, to ensure the installation and maintenance of the particularity; Certificate and the corresponding national certification products. Environmental Requirements for Explosion-Proof Electrical Equipment Applications: Explosion Hazardous Environments / Workplaces with Flammable / Explosive Atmospheres / Vapors. Explosive atmospheres / workplaces with combustible dust. Such environments are common in environments / workplaces where both flammable and explosive gases / vapors and combustible dusts coexist, in solid chemical finished goods shops and their transport, packaging, weighing and coating processes. With the development of modern chemical industry, this situation will become more and more popular. Therefore, the selection of explosion-proof electrical equipment in such places has drawn more and more attention from the design department and petrochemical enterprises. In the above three cases, there are also environments / workplaces where corrosive media and other special conditions (high temperature, high humidity, low temperature, dust, rain, water and vibration) are affected simultaneously. Explosion-proof electrical equipment selection: According to the level of the explosion risk, gas / vapor dangerous places are divided into: Zone 0, Zone 1 and Zone 2, their division mainly depends on the release source (explosion hazard source) the release level, of course, The structure of the building, the capacity of the ventilation facilities and the natural factors in the place will all affect the division and even have a great impact. In the modern petrochemical project, the No. 2 area accounts for more than 60%, while the No. 1 area occupies about 20 ~ 30%. The old chemical enterprises generally account for about 50% of the total area No. 1 and No. 2 respectively. Zone 0 Locations are generally confined to petroleum and chemical installations or to smaller outlets. For Zone 1 and Zone 2 sites, enterprises are generally willing to choose the type of explosion-proof electrical equipment used in Zone 1 for safety reasons. If the application environment / site is outdoor or slightly corrosive, sand and rainwater Zone 2, are often willing to choose a more protective type of explosion-proof electrical equipment, such as: increased safety explosion-proof composite "de", increased safety "e "," N "type and so on. In addition, on the temperature group, it is desirable to select a group that is above the ignition temperature of the application ambient gas.

Tungsten Carbide Grits

Tungsten carbide grits are small particles or granules of tungsten carbide, a compound made up of tungsten and carbon atoms. They are extremely hard and have a high resistance to wear and abrasion, making them useful in a variety of industrial applications.
Tungsten carbide grits are often used as abrasives in cutting tools, grinding wheels, and sandpaper. They can also be used as an additive in metal alloys to improve their hardness and wear resistance. Additionally, tungsten carbide grits are used in the mining and drilling industry for rock drilling and excavation.
These grits are available in different sizes and shapes, such as spherical or irregular particles, depending on the specific application. They are typically produced through a process called sintering, where Tungsten Carbide Powder is heated and compressed to form a solid material.
Overall, tungsten carbide grits are highly valued for their hardness, durability, and resistance to wear, making them essential in various industries where high-performance materials are required.
