Explosion-proof emergency light introduction and use common sense
Explosion-proof emergency light can be divided into one type of light and split type light. One kind of light is the type of light source that is used in the normal working condition to be used as the light, while the split light is just the kind of light. Emergency lights used in emergency facilities. This kind of light source is mainly powered by a battery type power supply. When the power supply facility completely stops supplying power, this kind of light source will immediately activate its entire lighting system. To achieve a certain lighting effect. During the installation process, it can also be set to switch mode operation, or it can be set to automatic mode operation.
This type of explosion-proof emergency light mostly uses LED light source body for illumination, so as to save power while prolonging the service life of the light source body, and is highly efficient and energy-saving. Since the overall design concept of this lamp source is used for emergency, the overall circuit design is more reasonable, and the electrical efficiency is higher. It is safe and reliable to use, and it can be exempted from the use of this lamp source in everyday life. Due to regular maintenance, it has become a preferred source of light among many large shopping malls and companies.
Explosion-proof emergency lights should pay attention to some common sense when used:
1. In the process of transportation, the lamps should be installed in the configured carton, and some foam should be filled to reduce the loss of light bulbs caused by the shock.
2. In the installation of explosion-proof emergency lights , the lamps should be installed at the exit or on the emergency track, which can have better results in emergencies.
3. When using this type of lamp, the surface temperature of the lamp will increase, which belongs to some common safety phenomena. However, do not touch the center of the lamp with your hand, because its center temperature is higher than the outside temperature. Many, so as not to be burned.
4. When repairing explosion-proof emergency lights , be sure to cut off the power to prevent accidents.
The performance features of explosion-proof emergency lights are mainly automatic emergency functions, and they have a long emergency time. Don't worry about stopping work without electricity. It adopts a new type of LED light source, so that its power is reduced, its service life is prolonged, and its energy efficiency is high. Its internal structure design is more optimized and reasonable, has a higher electrical efficiency, so as to achieve higher reliability and energy-saving, in addition, this explosion-proof emergency light in the appearance of a relatively lightweight alloy shell, waterproof resistance Impact, avoiding some insecure factors. Its surface has been made using recent methods. It has strong corrosion resistance, and even if it works in very bad weather, it will not cause sudden changes.
PVC Resin
PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.
PVC Resin usually inculde carbide based and ethylene based. K66-K68 PVC RESIN, K59-K55 PVC RESIN, K71-K73 PVC RESIN. PVC RESIN SG5, PVC RESIN SG3, PVC RESIN SG8.
According to the different application scope, PVC can be divided into: general-purpose PVC resin, high polymerization degree PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a crosslinking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
According to the method of obtaining vinyl chloride monomer, it can be divided into Calcium Carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. Suspension process polyvinyl chloride is the largest variety in output, accounting for about 80% of the total output of PVC. Suspension method PVC is divided into six models according to absolute viscosity: XS-1, XS-2--XS-6; XJ-1, XJ-2--, XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-compact type.
