What kind of paint is used for large machinery and equipment?
Since the rust-proof primer of the mechanical equipment is a first-class paint coating on the surface of the machined machine or machine parts covering the metal surface, it is the beginning of the entire mechanical equipment spray paint work, requiring mechanical rust-proof primer And the substrate metal must have a very good acid and alkali resistance, rust resistance, resistance to oil and resistance to salt spray resistance, while the substrate must have a very good adhesion, and the middle of the paint paint or anti Rust base paint with a good match.
The medium paint of the machine is the paint used between the rust-proof primer and the finish, which requires more middle-layer paint to be firmly attached to the surface of the primer, and better with the top coat Layer together, so it plays a very important role. In addition to the requirements of the middle layer of paint with the upper and lower coating finish primer has a very good adhesion and fusion strength, but also should have a cover to eliminate the surface of mechanical equipment, trachoma, uneven, improve the entire mechanical equipment surface Flatness.
At present, engineering machinery and equipment manufacturers use anti-rust primer specifications are numerous, there are single-component paint also has two-component acrylic paint, polyurethane paint, nitro paint, epoxy primer, acrylic corrugated paint, polyurethane hammer Varnish, acrylic paint, high gloss paint, two-component quick-drying epoxy paint, polyurethane paint. Single-component acrylic paint, modified nitrocellulose paint and so on because of the drying speed, summer spray paint, often dry spray phenomenon, the surface of the sprayed machinery and equipment can not form a continuous film coating, resulting in a large number of Powder, the impact of the construction of the topcoat, one-component anti-rust primer and polyurethane finish paint is not good. Two-component paint although the construction of some trouble, but in the gloss and adhesion and other important performance was significantly higher than the one-component paint.
Mechanical equipment Topcoat is the last layer of paint in the entire paint coating of the construction machinery, which plays the most critical decorative and protective effect throughout the coating, and determines the life and appearance of the mechanical paint coat. It is because of such a paint where it is particularly special position, which requires finish than the bottom of the anti-rust paint has a better function. First of all, weatherability is an important indicator of topcoat, it requires the topcoat in the extreme temperature change wet, wind and rain hail weather conditions, do not change color, no yellowing, without losing light, no blistering, no cracking , Do not paint, do not paint, paint does not fall off
Mechanical equipment with paint generally pay attention to protection and decoration, different requirements of different materials using different varieties, decorative topcoat general selection of art paint, enamel, high gloss or matte paint, primer generally use rust and corrosion, all manufacturers choose Combined with their own requirements, primer from the fundamental role of protection, facial paint from the fundamental protection and decoration.
