With the rapid development of petroleum, chemical, military, engineering, factories, mining, and other industries, explosion-proof distribution boxes are used more and more widely in production, storage, and rescue, and more and more varieties. How to prevent the accidental explosion of the distribution box in an explosive gas hazardous location has become a very important issue.
At present, the production technology level of explosion-proof electrical appliances is developing rapidly, and the speed of product replacement is also very fast. The variety of series increases, the types of explosion-proof increase, the power range expands, and the explosion-proof standards also tend to improve. After years of development, China's explosion-proof electrical equipment can basically meet the requirements of major industrial and mining departments such as coal, petroleum, and chemical industry. At present, in the general electric machinery production process, the domestic explosion-proof distribution box can fully meet the technological requirements, whether in terms of functionality or reliability, it is not worse than that of foreign imported motors, and it can even completely replace some foreign imported explosion-proof distribution Wire box. In the future, as the safety requirements of various industries increase, China's explosion-proof junction box equipment will usher in greater development.
The electrical equipment of the explosion-proof distribution box must be connected to the power supply network through wires or cables to form a system to complete its use function. However, the connecting wires or cables cannot be infinitely long, and there are many places in the connection process that need to be connected in series or in parallel for wire tapping. This will inevitably cause the joint parts to be exposed, which may easily lead to accidents. Explosion-proof branch box products are products manufactured to solve such problems, in order to further ensure safe production. The shell of the explosion-proof distribution box is mainly made of cast aluminum alloy. There are many incoming and outgoing lead-in devices as required, and there are wiring terminals in the box for connection or tapping. Most of these products are made of explosion-proof type or increased safety type, the size is large or small, the difference is large, and the explosion-proof level can reach â…¡C level.
Explosion-proof distribution box is composed of box body, box cover, terminal block, compression seal ring and compression bolt. The box cover and box body are made of light-weight, high-strength alloy aluminum with a magnesium content of not more than 6% (mass percentage). Non-thread sealed pipe thread is used for inlet and outlet. The inlet is made of G1, G1 / 2 and G3 / 4 pipe threads, and the outlet is made of G3 / 4, G1 / 2 pipe threads. After the wire and cable are inserted into the compression bolt, protection ring and sealing ring in turn, tighten the compression bolt to deform the sealing ring and press the wire and cable to achieve the purpose of sealing, explosion-proof and waterproof.
The explosion-proof electrical equipment market has great room for development. Large-capacity, intelligent complete electrical equipment will be welcomed by the market. With the rapid development of the petrochemical industry, it will definitely bring better development opportunities to the factory explosion-proof electrical appliance industry. Therefore, during the "Thirteenth Five-Year Plan" period, it will still be a stage of rapid development of factory explosion-proof electrical appliances. During this period, the market concentration of key enterprises of factory explosion-proof electrical appliances will be further improved, products will be diversified, and market competition Will be more intense.
Today's society is a society of rapid development of science and technology, and various new technologies are constantly coming out. In the field of electrical appliances, remote control, telemetry, remote control and communication functions have been completed, and the explosion-proof distribution box can do a lot of work in this regard, so that explosion-proof electrical appliances can make new progress in this control field.
Food additives are substances added to food to preserve flavor or enhance its taste, appearance, or other qualities. Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as with wines. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.
Food additives can be divided into several groups, although there is some overlap because some additives exert more than one effect. For example, salt is both a preservative as well as a flavor.
Sulfanlic Acid can be used as Food color for Lemon Yellow.
