Selection of wire threading pipe and switch panel: Selection of wire: For fire prevention, maintenance and safety, it is best to use the "national standard" copper core wire with Great Wall logo. The cross section of wire slot is generally: 1.5 square millimeter for lighting cable. Use the line to select 2.5 square millimeters, the air conditioning line should not be less than 2.5 square millimeters, the wiring line should use green and yellow two-color lines, and the switch line (fire line) can be used in any of red, white, black and purple. However, the color of the wire mesh used in the same home improvement project should be consistent.
Selection of threading pipe: The threaded pipe should be made of flame-retardant PVC pipe. The surface of the pipe wall should be smooth. The wall thickness should meet the strength of the finger. It should have a certificate of conformity, or use the special galvanized pipe of the national standard as the threading pipe. . Welcome to the company **http://
Material selection and installation of the switch panel: The size of the panel should be the same as the size of the embedded junction box; the surface is smooth, the brand logo is obvious, the anti-counterfeiting mark and the Great Wall logo of the national electrician safety certification; the switch should be flexible when the switch is opened, and the socket is stable. The copper sheet should have a certain thickness; the material of the panel should be flame retardant and sturdy; the switch height is generally 1200 mm to 1350 mm, the door frame edge is 150 mm to 200 mm, and the socket height is generally 200 mm to 300 mm.
Coal Activated Carbon For Recycling Of Solvents
Using high quality coal as raw material for solvent recovery, coal is mainly used in the recovery of benzene, toluene, ether, alcohols, gasoline, three, methyl chloride, organic solvents and other hydrocarbons, as well as the vapor recovery of hydrocarbon compounds.
Use: Used in the seperation and recycling of aethers, ketons, alcohols, tetrahydrofuran, methylene dichloride, trichloromethane, trichloroethylene, chlorinated polyvinyl chloride, carbon bisulfide, benzene, gasoline etc.
