Cold galvanized cable tray is using electrolytic equipment cable tray after degreasing, pickling, into the composition of zinc salt in the solution, and connect the cathode electrolytic equipment, across from the cable tray to place zinco, connected to the anode electrolytic equipment, power supply is connected using current from the positive to the negative directional moving deposits a layer of zinc in cable bridge frame, galvanized after cold cable bridge is the first plating processing, is used as antiseptic effect.
Environmental performance:
As with heavy-duty coating, cold galvanized cable tray production and coating engineering also involves the environmental protection and construction personnel and the public's occupational health and safety, and environmental protection is also cold galvanized cable tray are the main development direction.Cold galvanized cable tray with excellent environmental performance, mainly embodied in the following four aspects:
(1) composition does not contain heavy metal, such as Ph, cr, Hg,
(2) type vest in thick film materials, thixotropic performance is good, after fully mixing, add or not add thinner, less coating construction.Due to the cold galvanizing solid content as high as 77%, an airless spraying can obtain higher film thickness, reduced the amount of volatile organic solvent, reduce the energy consumption of drying, these are conducive to environmental protection.
(3) after test to prove: the vast majority of cold galvanizing solvent and thinner, do not contain toluene, ketone, halogenated hydrocarbon is toxic organic solvents, etc.
(4) cold galvanized cable tray is instead of hot dip galvanized, electric arc spraying zinc (hot) one of the best materials, to reduce the "three wastes", reduce the energy consumption and enhance the role of the social benefits of environmental protection is more obvious.
