Jiangmen steel some hidden problems

Jiangmen steel coating application of some common morbid film, there is also cause painting project quality hidden problems. There are:

    1, a unit of the project, we should try to use the same brand of paint products manufacturers, in some cases with the use insisted, should do first binding experiments matching each other, no problem confirmed before use;

    2, pay attention to the shelf life of the paint, most of the shelf life of the coating is usually a year or so, some varieties of only six months;

    3, two-component or three-component coating fabricated products shall be specified in the instructions within the time runs out overnight to ban the manufacture of unused paint diluted or blended mix;

    4, special paint special features, usually can not be used to support other paints, they have their own coating system, such as large storage tanks antistatic coating, non-toxic coating the inner walls of the large-diameter pipes for drinking water and smelting career high temperature coatings;

    5, exposed to the environment can not finish doing Jiangmen steel coated with epoxy, because of poor weather resistance and UV intolerance, long after the film shines light volatile, chalking, cracking until fall;

    6, steel shot blasting roughness master when appropriate rough pockmarked face can enhance the adhesion of the coating and the substrate, on the progress coating quality is good, but too much, you need to increase the thickness of the coating filled high and low peaks; otherwise, at the crest of the ribs is equal to the thickness of the coating thinned, weakened where the shielding effect and stain resistance. Therefore, the roughness of the master, usually should be controlled at 40 ~ 60μm mercy.
