    Core tips: selection and precautions of fire retardant coating for steel structure: (1) the fire retardant coating selected in the actual project must have the test report and production license approved by the national testing agency for its fire resistance performance (2) The load-bearing steel structure of civil buildings and large-scale public buildings should adopt fire-proof coating Generally, the architect and structural engineer should select the coating type (thin coating type or thick coating type) and construction method according to the fire resistance rating and fire resistance time limit of the building and cecs24 (3) Thin coating fire retardant coating should be selected preferentially Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating House News: selection and precautions of fire retardant coating for steel structure: (1) the fire retardant coating selected in the actual project must have the test report and production license approved by the national testing agency for its fire resistance performance (2) the load-bearing steel structure of civil buildings and large-scale public buildings should adopt fire-proof coating Generally, the architect and structural engineer should select the type of coating (thin coating type or thick coating type) and construction method according to the building fire resistance rating and fire resistance time limit, and according to cecs24, technical code for application of fire-proof coating for steel structures (3) the thin coating type fire retardant coating should be selected preferentially When the thick coating type coating is selected, the decorative surface layer should be used for insulation Ultra thin fireproof coating can be used for the parts with high decoration requirements (4) for the thickness of fire retardant coating, the fire resistance test data of actual components should be directly used When the cross-section size or shape of the component is different from that of the test standard component, the required thickness of the fireproof coating shall be calculated according to the method in Appendix 3 of the current technical code for the application of fireproof coating for steel structures (cecs24) (5) for steel structure in outdoor environment, fire protection is generally not considered However, the indoor and outdoor fire protection design of petrochemical enterprises shall be carried out in accordance with the code for fire protection design of petrochemical enterprises When the outdoor steel structure needs fire protection, the special outdoor fire retardant coating shall be used, and the anti rust primer shall be used as the primer (6) facing fire retardant coating (applicable to wood structure with combustible base material) shall not be used for fire protection of steel structure (7) when the important steel column components are protected by fire retardant coating, bt518 thinks that the thick coating fire retardant coating should be used generally, and the joint should be thickened When the bonding strength of the fireproof coating is less than 0.05Mpa, the steel wire mesh connected with the steel members shall be set in the coating (8) when the load-bearing steel beam components adopt thick coating fire retardant coating, the important joint parts should be thickened In any of the following cases, the steel wire mesh connected with the steel beam shall be set in the coating ① steel beam subject to vibration; ② beam with coating thickness greater than or equal to 40mm; ③ beam with fireproof coating bonding strength less than or equal to 0.05Mpa; ④ beam web height greater than 1.5m (9) when there is a technical and economic basis, the important load-bearing components can adopt the fire prevention method of fire-resistant steel plus fire-retardant coating The fire prevention design and technical requirements for material performance, structure construction and other aspects can refer to the provisions of Shanghai local standard technical code for fire protection of steel structures (10) the construction of fire retardant coating shall be undertaken by a professional team, and the home of inspection and acceptance coating shall be focused on coating, diatom mud, paint coating, coating process, news information and coating of fire retardant coating, diatom mud, paint coating, coating process according to code for acceptance of construction quality of steel structures (gb50205) and technical code for application of fire retardant coating of steel structures (cecs24), Decoration knowledge and effect drawing of fireproof coating,
