Current Position:首页 > News > Dynamic Factors causing paint cracking on the surface of steel-lined plastic storage tanks Date：2017-10-02 16:53:50 Views：
Steel lined plastic storage tankThe anti-corrosion coating on the surface of the tank is mainly epoxy asphalt anti-corrosion coating, which will delaminate and crack under the influence of the external environment. The main reason for the cracking of the paint film on the surface of steel-lined plastic storage tanks is that the paint film shrinks improperly when it is drying and curing. Therefore, the problem of paint cracking on the surface of the storage tank cannot be ignored.
Steel lined plastic storage tankThe main reasons why the paint layer peels off and cracks are as follows:
1. The paint film on the surface of the steel-lined plastic storage tank is too thick during spraying. Under normal circumstances, if the thickness of the epoxy asphalt exceeds 120 microns, cracking will basically occur;
2. The surface roughness of the storage tank is too low, especially on the weld bead, where uneven roughness often occurs;
3. Relatively speaking, the humidity is too high, and the ventilation effect is relatively poor, so the surface will solidify quickly, and the paint film will also crack.
The above are the main causes of paint cracking on the surface of steel-lined plastic storage tanks. Only by knowing the reasons can we better carry out targeted prevention of steel-lined plastic storage tanks.
