Advantages and Disadvantages of Real Stone Paint Billboards
What is fluorocarbon coatings? What is the function of fluorocarbon coatings? Is there any harm? Today the editor will take you to take a look. Fluorocarbon coating. You may have only heard of fluorocarbon coatings recently. In fact, fluorocarbon coatings were produced in 1938. Due to technical problems and various reasons at the time, it was not until 1982 that fluorocarbon coatings overcame the original shortcomings and achieved Large-scale utilization. I
Advantages and disadvantages of fluorocarbon coatings
Fluorocarbon coatings are coatings with fluororesin as the main film-forming substance. Fluorine resin coatings have many advantages, such as weather resistance, heat resistance, low temperature resistance, non-stickiness, etc., so they are very popular among people. Fluorine coatings are widely used in various fields such as construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, home decoration, etc., and have become the coating brand with the highest compre hensive performance.
Fluorocarbon coating has excellent physical and mechanical properties. It has good corrosion resistance, high hardness, good wear resistance, and excellent Physical properties, etc. Moreover, the surface of fluorocarbon coating can be self-cleaned by rainwater, which eliminates the need for maintenance and cleaning. Fluorocarbon coatings also have strong adhesion and are suitable for almost any material. Not only that, fluorocarbon coatings also have ultra-long weather resistance, no chalking, no fading, and long service life. This is an advantage that other coatings cannot match. .
Although it has advantages, it also has disadvantages. Fluorocarbon coatings have certain limitations. When constructing exterior walls, the construction conditions and supporting coatings are very demanding. Moreover, it has poor elasticity, unstable performance, and is prone to cracking. . Fluorocarbon coatings seriously pollute the environment, are expensive, easily cause waste of resources and energy, and produce a large amount of poisonous gas in the event of a fire. Therefore, you must be careful when using fluorocarbon coatings.
The application of fluorocarbon coatings first appeared on the tops of factories and warehouses. Later, it was widely used in road and bridge construction. Due to the impact of road and bridge construction on Anti-corrosion requirements are very high, so fluorocarbon coatings are a good choice. The market for fluorocarbon coatings is also very good in the construction field. They are used in Fudong International Airport, Hongkou Stadium, etc. After many years of use, the colors are still gorgeous and intact. Fluorocarbon coating is also used in TV towers and overhead antennas. Due to its own advantages, it saves a lot of maintenance and cleaning costs.
The role of fluorocarbon paint
Fluorocarbon paint is a type of outdoor high weather-resistant paint that is attracting more and more attention. , widely used in the decoration and protection of bridges, tankers, roofs, walls, railings, plastic building materials, trains, airplanes, ships, automobiles, road signs and billboards, highway guardrails, and large steel structures.
1. Fluorocarbon paint protects light and color.
That is to say, fluorocarbon paint can maintain the color and gloss of the paint for a long time, and the process of loss of gloss and discoloration caused by the external environment (mainly ultraviolet light) is slow. Ordinary paints are particularly prone to loss of gloss, discoloration, yellowing, chalking, etc. in outdoor environments, and their appearance cannot be maintained.
2. The protective effect of fluorocarbon paint
Fluorocarbon paint has good corrosion resistance and is suitable for salt spray corrosive environment, chemical atmospheric environment, urban pollution environment, acid rain, and haze. It has good tolerance to other environments and can effectively protect the base coating and steel structure from corrosion. Ultra-long weather resistance. Long-term outdoor use and artificial accelerated aging tests show that the fluorocarbon bonds on the fluororesin molecular chain in fluorocarbon coatings can resist the degradation of ultraviolet rays, and have super weather resistance (outdoor service life) that ordinary coatings cannot match. more than twenty years).
Excellent anti-corrosion effect. The fluorocarbon coating can pass the 3000-hour neutral salt spray test. It is resistant to all strong acids, strong alkali and strong oxidants. Through multi-layer coating, the decoration of each coating is used. It has the functions of heat insulation, shielding, corrosion inhibition and cathodic protection, and can achieve the purpose of anti-corrosion and decoration of the substrate for decades.
3. Decorative effect of fluorocarbon paint
As a type of topcoat, fluorocarbon paint comes in a variety of colors (various solid colors and metallic colors, etc.) , the gloss can be selected from matte, flat, matte, etc., providing designers and owners with rich imagination space and strange decorative effects.
4. Self-cleaning effect of fluorocarbon paint
The self-cleaning effect is also one of the unique functions of fluorocarbon paint. The surface of fluorocarbon paint has low free energy and is free of oil stains. , haze and floating dust, etc., are not easy to adhere to the surface of fluorocarbon paint. Once the rainwater washes it off, it will be as clean as new without leaving any rain marks.
Although fluorocarbon coatings are mostly used for exterior wall construction, using fluorocarbon coatings for interior decoration is also a good choice, but the price is on the high side. If your family conditions are good, you can consider it. Water-based fluorocarbon coatings are more environmentally friendly and have more obvious advantages. It is also a good choice to choose water-based fluorocarbon coatings. The above is the content about the functions of fluorocarbon coatings. I hope it can be helpful to everyone!
