As is well known, hot-dip galvanized cable trays are degreased and acid washed using electrolytic equipment, and then the cable trays are placed in a zinc salt solution and connected to the negative end of the electrolytic equipment. Place the zinc plate on the other side of the cable tray and connect it to the electrolysis equipment. The positive end is connected to the power supply, and the directional movement of current from the positive end to the negative end will deposit a layer of zinc on the cable tray. First, treat the galvanized cable tray, and then galvanize it, which has anti-corrosion effect.
Like heavy-duty anti-corrosion coatings, the production and painting of galvanized cable trays also involve environmental protection, as well as the occupational health of construction personnel and the public. Therefore, environmental protection is also the main development direction of galvanized cable trays. Galvanized cable trays have good environmental performance, which is mainly reflected in the following four aspects:
The ingredients do not contain heavy metals such as Ph, Cr, Hg;
It belongs to thick film materials with good thixotropy. After thorough mixing, it can be painted with almost no or no thinner.
Hot dip galvanized cable trays mainly have anti-corrosion properties and surface coatings that make the cable trays more beautiful. The color selection can match the indoor design aesthetic, and galvanized cable trays can be installed outdoors.
After testing, hot-dip galvanized bridge manufacturers found that most galvanizing solvents and diluents do not contain toluene, ketones, halogenated hydrocarbons, and other toxic organic solvents.
Galvanized cable tray is a better material to replace hot-dip galvanizing and arc (hot) zinc spraying. It has a more significant role in reducing all three types of waste, reducing energy consumption, and enhancing the social benefits of environmental protection.
