Spray painting, in fact, is not a type of paint but a coating application technique. It involves loading the paint into a spray gun and using it to achieve large-scale coating by spraying. The paint that is applied is thin and even, capable of uniformly coating surfaces with varying geometries, including those with holes, gaps, and uneven textures. This method is also more rapid and effective for coating large surfaces compared to brushing. Hence, it is widely used in the construction industry. Let Ningbo Yuhang take you on a journey to understand it better.
Counting the Pros and Cons of Spray Paints:
The air spray gun is simple and practical, with a relatively low price. When paired with an air compressor, it forms a complete spray system, allowing for convenient spray operations in various locations.
2. High-quality Coating; The air-sprayed atomization effect is excellent, resulting in a uniform and aesthetically pleasing coating after application.
3. High Versatility in Operation - Airless spraying is nearly applicable to all types of paints and coated materials, with low training requirements for workers.
4. Low paint utilization rate; air atomization causes paint to scatter everywhere, wasting paint, with utilization rates only around 50%. The scattered paint pollutes the work environment and causes harm to the body.
5. High coating efficiency: Airless spraying can coat 150-200 m2 of workpieces per hour, 8-10 times more than brush painting. However, frequent material replenishment for the air spray gun affects work efficiency and increases labor intensity.
Coating paints are categorized by material volume density into lightweight, medium-heavy, and heavy-duty types. Lightweight coatings are used for insulation and heat insulation linings, medium-heavy coatings can serve as both insulation linings, while heavy-duty coatings are primarily used for working linings.
Thermal spray coatings have now become a widely used, non-shape refractory material for many industrial furnace linings. They can be used both in cold state for constructing, repairing furnace linings, and as protective coatings, as well as for repairing linings in hot state.
