Precautions when using 100w LED explosion-proof lamp
LED explosion-proof lighting is one of the potential markets for LED lighting industry. With the application of LED lighting technology in general outdoor venues, indoor home lighting has gradually matured. Taking the Japanese market, where the LED lighting market is taking off the fastest, as an example, many companies have seen high-level industrial LED explosion-proof lights. The most widely used is the 100w LED explosion -proof lamp. The 100W LED explosion-proof lamp is widely used in special working environments where electricity and dust are flammable and explosive, such as petrochemical, chemical, mining, semiconductor, shipbuilding, food, pharmaceutical factories, spray paint, etc. .
100w LED Explosion-proof lamp notes:
1. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent part) of the lamp to prevent static electricity.
2. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, stripped, and corroded. If so, use should be stopped and repaired and replaced in time.
3. The light source should be turned off in a timely manner to notify the light to be replaced, so as to avoid the ballast and other electrical components being in an abnormal state for a long period of time because the light source cannot be started.
4. If the accumulated water in the cavity of the lamp used in the humid environment should be cleared in time, replace the sealing parts to ensure the protective performance of the enclosure.
5. When you open the lamp cover, you should press the warning board to open the cover after turning off the power.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to improve the light efficiency of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
8. The sealed part of the lamp should not be frequently disassembled and opened. Patent zone road sealing technology; more in line with national explosion-proof new technology.
Chrome Green
cas no: 1308-38-9
EINECS : 215-160-9
Chromium green generally refers to chromium trioxide. Chromium oxide is an inorganic substance with the chemical formula Cr2O3. It is light green to dark green fine hexagonal crystal. It turns brown when hot and green after cold. The crystal is extremely hard and stable, and there is no change even when hydrogen is introduced under red heat. Soluble in heated potassium bromate solution, slightly soluble in acids and bases, almost insoluble in water, ethanol and acetone. And irritating.
1. Lead chrome green is the main coloring pigment in the coating industry, and most green paints are prepared with this pigment. In addition, it is also used in paint and plastics. Its application range is very similar to lead chrome yellow. Because the composition contains chrome yellow, pay attention to the toxicity of lead in application. Lead chrome green contains iron blue and the oxidant lead chromate. Therefore, when the dust meets Mars, it may spontaneously ignite. It should not be careless when drying and crushing. The burned lead chrome green completely loses the characteristics of green pigment and changes into dark brown yellow material. In addition, when making nitrocellulose lacquer, the rolling process is not directly rolled with lead chrome green, but after the lead chrome green is grind into the pulp, the process is prevented from burning at the time of rolling.
2. Used in metallurgy, ceramics, refractories, pigment raw materials and organic synthesis catalysts.
3. Used as analytical reagent and catalyst.
4. It is used as a filler for coloring, wear resistance and corrosion resistance of adhesives and sealants. It can also be used as a colorant for enamel, ceramics, artificial leather and building materials; Organic chemical synthesis catalyst; Sun resistant coating and special ink for printing paper money.
5. as a coloring agent for cosmetics, it is mainly used for eye cosmetics, but not for oral and lip cosmetics. It is not recommended for facial cosmetics and nail polish.
6. Chromium trioxide is one of the main components of silver plating dipping solution. The newly prepared chromium trioxide is an important raw material for preparing chromium fluoride and chromium bromide.
