1, the ambient air temperature:
The trolley wire can be applied to both indoor and outdoor environments depending on the equipment requirements. The normal operating temperature of the indoor trolley line is -5°C~40°C, and the normal operating temperature of the outdoor trolley line is -25°C~40°C. And the average temperature difference of the trolley line within 24 hours must not exceed 35°C.
2. Atmospheric conditions:
Indoor Sliding Line: Atmospheric relative humidity does not exceed 50% when the ambient air temperature is 40°C, and the contact line at a lower ambient temperature can have a higher relative humidity. Outdoor slide wire: When the outdoor temperature is 25°C, the relative humidity of the trolley can be as high as 100% for a short time.
3, altitude:
The altitude of the place where the trolley line is used should not exceed 2000m. Note: For the trolley line device with an altitude of more than 2000m, the air cooling effect and the decrease of the dielectric strength need to be taken into account. The trolley line operated under the above conditions should be based on the manufacturer. The design and use of the agreement with the user.
4. The pollution level of the environment where the trolley line is located:
The indoor trolley line should not be lower than 3, and the outdoor trolley line should not be lower than 4.
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.
