Spray coatings are amorphous refractory materials that are constructed by mechanical spraying using pneumatic tools. They are composed of refractory aggregates, powders, and binders (or admixtures). The following is a detailed analysis of the research and development and application of spray coatings:
1. Research and development of spray coatings
Material innovation:
The research and development of spray coatings is constantly developing in the direction of high performance and multi-function. For example, the new polyurea coating is not only waterproof and wear-resistant, but also the roof strength after spraying is doubled, and it can also be used as a walking surface.
Environmentally friendly spray materials are also the focus of current research and development, such as water-based coatings and VOC-free coatings. These materials are of great significance in reducing environmental pollution and protecting the ecological environment.
Process improvement:
The continuous innovation of spraying technology is an important factor in promoting the development of spray coatings. For example, the successful development of high-precision intelligent spraying equipment indicates that the spraying industry is moving towards a more intelligent and refined direction.
The trend of intelligence and automation of spraying equipment is also becoming increasingly obvious. For example, the introduction of robot spraying systems has greatly improved production efficiency and coating quality.
Application field expansion:
With the continuous advancement of spraying technology, the application field of spray coatings is also expanding. For example, polyurea coatings have been widely used in sports stands, undersea tunnels, automobile manufacturing, national defense and military and other fields.
Anti-corrosion epoxy resin coatings are also widely used in steel structure corrosion protection, automobile manufacturing, electronics and electrical, railway transportation, ship aviation, chemical petroleum, architectural decoration and other fields due to their excellent anti-corrosion performance.
2. Application of spray coatings
Industrial field:
Spray coatings are widely used in industrial kiln linings. They can be used to construct and repair linings and apply protective layers in cold states, and are also suitable for repairing linings in hot states.
In the field of automobile manufacturing, spray coatings are widely used in the anti-corrosion and decoration of car bodies, engines and other parts.
In the field of aerospace, spray coatings are used to provide corrosion resistance, prevent wear and minimize resistance, which ultimately helps to improve the overall efficiency and safety of aircraft.
Architectural field:
Spray coatings play an important role in the decoration and protection of building exterior walls. For example, exterior wall coatings such as water-based sand paint and real stone paint are widely welcomed for their good stone-like effect, strong weather resistance and simple construction.
Self-cleaning exterior wall paint is also a new type of paint that has emerged in recent years. It has a special coating on its surface. When it encounters rain, dirt and dust will be automatically washed away, keeping the wall clean and tidy.
Other fields:
Spray coatings are also widely used in fisheries, sports facilities and other fields. For example, spraying fishing net floats with polyurea coatings can extend their service life and reduce pollution.
In terms of sports facilities, polyurea coatings have been widely used in sports stands, and their excellent performance makes stands sprayed with polyurea coatings almost the standard of various sports venues.
3. Future development trends
Environmental protection:
With the increasingly stringent environmental protection regulations and the improvement of consumers' environmental awareness, environmentally friendly spray coatings will become the mainstream trend of future development.
Research and development of low-VOC, non-toxic and biodegradable spray coatings will be an important direction in the future.
Intelligence:
The intelligence and automation level of spraying equipment will continue to improve to meet the needs of large-scale and high-efficiency production.
The research and development and application of high-precision intelligent spraying equipment will promote the development of the spray coating industry to a higher level.
Multifunctionality:
Research and develop spray coatings with multiple functions, such as antibacterial, self-repairing, luminous, etc., to meet the diverse needs of different fields and consumers.
The research and development and application of spray coatings play an important role in many fields and show a trend of continuous development and innovation. In the future, with the continuous advancement of technology and the continuous changes in market demand, the spray coating industry will continue to develop in a more environmentally friendly, intelligent and efficient direction.
