Waterproof, dustproof and anticorrosion distribution box maintenance and maintenance

Many distribution facilities of chemical processing plants use waterproof, dustproof, anticorrosion and explosion-proof power distribution boxes. Because the dust will float in the air during processing, these dusts will simply react with the sparks. Therefore, how to prevent these dust from reverberating is the factory. The manager's first question.

Summarize the use of places such as indoor and outdoor workplaces, China's coal industry, PetroChina, Sinopec, CNOOC, power, metallurgy, railways, steel, ships, *, aerospace, * fire, chemical, government departments, venues, transportation, And large-scale enterprise application needs. Note: Please specify IIC level.

If you want to use the waterproof, dustproof, corrosion-proof and explosion-proof power distribution box to extend its service life, you need to protect yourself. First and foremost, it is necessary to seriously learn how to operate the machine with the engineering personnel of the installation, so that it will not be damaged because you cannot operate it later. Many customers do not operate in accordance with the correct operation method to save energy, so that the waterproof, dustproof, anti-corrosion, and explosion-proof distribution box presents many questions that should not be presented, and often has a bad influence on its service life. To prevent the onset of some problems, technicians should have enough knowledge of the correct operation of the distribution box and follow these correct methods of operation during normal times. In addition, the manufacturers of each distribution box will clarify the production capacity of the equipment, as well as its various parameters and performance. This requires that when the equipment is used, it must be operated according to its scale of operation. Do not repair it yourself, but rather contact the after-sales service personnel in a timely manner.

Epichlorohydrin, 3-Chloro-1, 2 - epoxypropene, chloropropylene oxide ,ECH .

 

Molecular Formula: CH2OCHCH2Cl, C3H5OCl 

Properties: It is a volatile, unstable colorless liquid with irritating odor similar to chloroform and ether. Molecular weight is 92.85, density, 1.1806g/cm3, boiling point, 116.11°C, freezing point, -57.2°C, refractive index (nd20), 1.4382, flash point (open cup), 40.6°C, and ignition point, 415°C. It is slightly soluble in water, miscible with many organic solvents, and able to generate azeotrope with a variety of organic liquids.
 
Main Applications: 
Epichlorohydrin is an important organic industrial chemical and a chlorine-consuming product in fine chemicals, mainly for producing epoxy resin, synthetic glycerin, epichlorohydrin rubber, nitroglycerine explosives, glass fiber reinforced plastics, and electrical insulation products, which are widely used in the chemical industry, light industry, transportation, medicine, electronics and other fields. It also can be used as solvent for cellulose ester, resin, and cellulose ether, and the raw material of plasticizer, stabilizer, surfactant, and chloroprene rubber.

Toxicity and Protection: It is highly toxic, absorbed through the skin, and irritating to skin and mucous membranes. In higher concentrations, it has the function of narcotism. When poisoning occurs, there will be eye irritation, conjunctivitis, rhinitis, lacrimation, cough, fatigue, gastrointestinal disorders, nausea and other symptoms. Serious poisoning may lead to anesthesia or even lung, liver or kidney damages. Lethal concentration of human beings is 20ppm. Lethal dose of rat is 5090mg/kg. The maximum allowable concentration in air is 5ppm (18mg/m3). Production equipment needs to be closed, air, circulating, and the operator, wear protective equipment. In addition, due to intense auto polymerization, epichlorohydrin can not be heated in the fire in case of container burst. As for reaction as reagent, it is appropriate to be diluted with inert solvent and slowly added. 

Packaging, Storage and Transport: 
As ferric chloride or stannic chloride can promote auto polymerization, epichlorohydrin should be stored in dry, clean iron barrel, 200kg each, and kept in a cool, ventilated, and dry place, away from fire and heat. Store and transport in accordance with the provisions of flammable toxic substances.
