How to improve the anti-corrosion and beautification effect of the 1500kg load-bearing steel wire pallet grid through efficient spraying technology?

Spraying, in short, is a process in which liquid paint is atomized into fine particles through a spray gun, and these particles are evenly sprayed on the surface of an object with the help of compressed air or electrostatic force. This process is widely used in the surface treatment of metals, plastics, wood and other materials, aiming to enhance the corrosion resistance, wear resistance, fire resistance and aesthetics of the materials. For steel wire pallet racks, spraying can not only form a dense protective layer that effectively isolates corrosive factors such as moisture and oxygen in the environment, but can also customize the appearance of the pallet rack by adjusting the color and gloss of the paint. , to meet the visual identification needs of warehouse management.

In the spraying process, the choice of coating is crucial. For the specific application environment of load-bearing wire pallet mesh frame, commonly used coating types include epoxy resin and polyurethane.
Epoxy Resin: Known for its excellent adhesion and chemical resistance. Epoxy resin coating can closely adhere to the surface of the steel wire, forming a hard and difficult-to-fall off protective layer, effectively resisting the erosion of corrosive substances such as acids, alkalis, salt spray, etc. In addition, epoxy resin coatings also have good insulation properties and heat resistance, and are suitable for the special requirements for pallet grids in the electronics, chemical and other industries.
Polyurethane: known for its excellent wear resistance, weather resistance and elasticity. Polyurethane coating can form a flexible coating that effectively absorbs external impacts and protects the wire pallet grid from physical damage. At the same time, polyurethane coatings also have a wide range of color and gloss options, which can meet the high standards for the appearance of pallet racks in industries such as food and medicine.

Thorough cleaning and pre-treatment of the wire pallet grid before spraying is a critical step to ensure good bonding of the paint to the substrate. The preprocessing process usually includes the following links:
Degreasing: Use solvent cleaning or alkaline cleaning agents to remove oil, grease and other impurities on the surface of the pallet grid to avoid affecting the adhesion and drying effect of the paint.
Rust removal: Thoroughly remove rust, oxide scale and other attachments on the surface of the steel wire through sandblasting, pickling or mechanical grinding to ensure that the paint can evenly penetrate into the base material and form a strong bonding layer.
Phosphating or passivation: For specific application scenarios, if it is necessary to enhance the adhesion and corrosion resistance of the coating, phosphating or passivation can be used to form a dense conversion film on the surface of the steel wire to further improve the protection of the coating. Effect.

When implementing the spraying process, parameters such as the spraying environment, paint ratio, spraying pressure, and spray gun distance need to be strictly controlled to ensure that the coating is uniform, without leaks, bubbles and other defects. According to the structural characteristics and size of the pallet grid, select appropriate spraying methods and equipment, such as manual spray guns, automatic spraying lines or high-pressure airless spraying, etc., to improve spraying efficiency and coating quality.

In view of the special environments that steel wire pallet racks may encounter during use, such as high temperature, humidity, salt spray, etc., the weather resistance, heat resistance or salt resistance of the coating can be further improved by adding functional fillers or adjusting the coating formula. Fog performance ensures stable operation of pallet grids under extreme conditions.

In addition to improving anti-corrosion properties, the spray coating process also provides a wealth of beautiful customization options for wire pallet grids. By adjusting the color and gloss of the paint, the appearance of the pallet grid can be differentiated to facilitate visual identification in warehouse management. For example, in the food industry, light-colored coatings that meet food safety standards can be used to avoid contamination of food due to peeling paint; in the electronics industry, static dissipative coatings can be used to reduce static damage to sensitive electronic components. Information such as company logos and barcodes can also be sprayed on the pallet racks to improve the informatization level of warehousing management.
