As a core protective component in high-risk environments such as petrochemical plants, mines, warehouses, and high-rise buildings, the quality of construction and installation, as well as the level of daily maintenance, directly determines the performance and service life of explosion-proof composite panels. If construction is not standardized or maintenance is inadequate, even high-quality explosion-proof composite panels may experience problems such as loose installation, protective failure, and aging damage, creating potential safety hazards.
Before construction and installation, thorough preparatory work is necessary to lay the foundation for standardized construction. First, the specifications, model, and explosion-proof rating of the explosion-proof composite panels must be verified to ensure consistency with the project design requirements. Simultaneously, the appearance of the panels must be inspected to confirm the absence of damage, deformation, hollow areas, coating peeling, or other quality issues. Substandard panels are strictly prohibited from use. Second, the substrate must be cleaned to ensure it is flat, dry, clean, and free of oil, dust, and debris. If the substrate is uneven, leveling treatment is required to prevent gaps or loosening of the panels after installation. Furthermore, suitable installation accessories (such as explosion-proof bolts, sealant, and fasteners) must be prepared. Accessories must meet explosion-proof standards and be made of materials compatible with the panels; using ordinary accessories will compromise the protective effect.
During construction and installation, the standardized procedures must be strictly followed. First, the splicing of panels must be precise, with gaps controlled within 2mm. These gaps must be filled with specialized explosion-proof sealant to ensure a tight seal, preventing the penetration of explosive shockwaves and avoiding rainwater and moisture that could cause the panels to become damp and age. Second, the fixing method must be standardized, using explosion-proof bolts. The bolt spacing and fixing depth must meet design requirements. It is strictly forbidden to arbitrarily reduce the number of bolts or change the fixing position to ensure the panels are firmly fixed and prevent loosening or detachment during later use. Third, the surface of the panels must be protected during construction to avoid collisions and scratches, preventing damage to the coating that could affect its anti-corrosion and anti-aging properties. If damage occurs, it must be repaired promptly.
During the final stage of construction, thorough acceptance testing is essential to promptly identify and address any potential hazards. Acceptance should focus on checking the flatness and firmness of the installed panels, the sealing of joints, the proper installation of bolts, and the integrity of the panel surface. Simultaneously, random checks of explosion-proof performance should be conducted to confirm that the installed panels meet the design explosion-proof rating requirements and pose no safety hazards. After successful acceptance, all construction documentation should be compiled, and panel certificates of conformity, test reports, and construction records should be retained to provide a basis for future maintenance. If the acceptance fails, immediate rectification is required until the standards are met before the panels are put into use.
Routine maintenance is crucial for extending the service life of explosion-proof composite panels and ensuring their protective performance. First, regular inspections are essential. A comprehensive inspection should be conducted at least once a month, focusing on checking for surface damage, coating peeling, rust, etc., whether the sealant at the joints is aged or cracked, and whether bolts are loose. Any problems should be addressed promptly. Second, environmentally appropriate maintenance is necessary. If used in harsh environments such as humid, corrosive, or high-temperature conditions, the inspection cycle should be shortened, and the panel surface should be cleaned and treated with anti-corrosion agents regularly to prevent corrosive media and high temperatures from accelerating panel aging.
