1. The surface cleaning of fireproof coating manufacturers should be strictly inspected according to the process. Remove dust, iron filings, rust, grease, and other substances that interfere with adhesion, and perform rust prevention treatment on the substrate. The bottom coating of steel structure fireproof coating should be used in conjunction with the primer, which does not corrode the steel.

2. When spraying fireproof coatings on steel structures, the consistency of the sprayed layer, the pressure of the air compressor, and the distance between the nozzle and the component during spraying should be mastered. During the construction process, splashing was mainly observed, indicating that the construction parameters were unreasonable and should be adjusted. The amount of diluent in the coating should not be too much, otherwise the normal construction viscosity of the coating will decrease, and the coating cannot adhere to the surface of the steel structure.

3. Fireproof coating spraying protection should be trained by qualified professional construction teams with corresponding construction qualifications. A strict construction plan has been developed based on the characteristics of the project and product selection. According to the engineering requirements, check the physical and chemical properties of the coating according to the required proportion before the implementation of the project. Different parts of the expansion type fireproof coating should undergo foaming performance testing.

4. After the completion of the project, the coating thickness cannot be measured alone. The color, leakage, and cracks of the coating should be detected by visual inspection. The strength of the coating is tested using a 0.75-1kg hammer, and the roughness of the coating is measured using a 1m ruler. The coating should be smooth, without obvious dents, strong adhesion, no powder, loose, and floating slurry. Remove the mastoid process without any leakage, powder removal, or obvious cracks.

5. During the painting process, the coating must be dried and cured before reapplying. The protection method, construction frequency, and protective layer thickness of the coating should be determined according to the requirements of the construction design. The thickness of each coating should be moderate, and should not be too thick or unfolded to avoid a decrease in coating quality. Strictly follow the painting process and avoid safety hazards during construction.

6. The coating thickness should reach the design value. The joints of steel structure fireproof coating should be thickened. The requirements for spraying areas, surface treatment of components, filling of joints, preparation of coatings, spraying frequency, quality control, and acceptance shall comply with the current national standards of "Application Technology SP". Ecological application of fire-resistant coatings (CECS24). The thickness of the coating should be checked on the construction side. If cracks are common and wide, the process should be studied and analyzed correctly, and the coating ratio should be reasonable.

The construction price of fireproof coating manufacturers is only a few tens of yuan, but there are many guerrilla forces and some irresponsible decoration companies. Therefore, before the completion of concealed works such as ceilings, consumers must check whether the construction complies with standard procedures.

What is the combustion performance of fireproof coating?

In order to strictly control the quality of fireproof coatings, the fireproof performance of steel structure fireproof coatings is divided into two levels, namely level I and level 2, to prevent fires in enterprises. Due to its good fire resistance, fire-resistant coatings cannot achieve the desired fire prevention effect.

How to classify the combustion performance of fire-resistant coatings for steel structures?

Qualified fireproof coatings will swell and bulge on the surface of flames when received by torches and other artillery. There will be no combustion damage within a few minutes. There is basically no foam in counterfeit goods, but a large number of scattered fragments. Chongqing fireproof coating manufacturer
