Dry film thickness gauge

The steel structure fireproof coating has many superior performances that other anticorrosive coatings cannot match. The interference factors of the actual effect of the steel structure fireproof coating come from many aspects, the most important thing is the thickness of each part of the coating. We often use a coating thickness gauge to measure each layer, and strictly meet the required standards to improve the effectiveness of the steel structure fire protection coating as a whole.
1. Thickness of primerThe main function of the fire protection coating of the steel structure is fire protection, so the rust prevention work of the internal material also needs to be undertaken by the primer. When choosing an anti-corrosive primer, one needs to consider its compatibility with fire retardant coatings. The two should not only blend with each other, but also have strong adhesion.There are many types of anti-rust primers, but there are several common ones on the market and often used by the builders: alkyd zinc phosphate anti-rust primer, epoxy zinc phosphate anti-rust primer, epoxy zinc-rich primer Paint, inorganic silicon hydrochloride zinc primer. These are primer materials with good compatibility. According to the national standards, the constructor will control the thickness of the primer to about 60 microns. Dry film thickness gauge can be used to measure the dry film thickness2. The thickness of the intermediate paint meets the standardThe effect of the intermediate paint layer on the properties of the fire protection coating of the steel structure is effected in terms of thickness and stickiness. When preparing the intermediate paint of the fireproof coating of the steel structure, the builder needs to pay attention to whether the thickness of the intermediate paint is evenly applied. Waterborne epoxy cloud iron is a very common intermediate paint material, which can help to establish interconnections between different layers of fire retardant coatings.The builder must adhere to the basic construction process concept to ensure the permeability of the material and the stability of the rheological agent during the drying process. Usually used with a dry film thickness gauge, it can detect the thickness of the intermediate paint in time, and it is also conducive to the construction workers to make appropriate adjustments and changes.
