With the "green and sustainable development" gradually become the mainstream of industrial development. How to integrate into the construction of transportation and achieve high-quality development of transportation has become a topic of common concern in the industry. Reasonable selection of coating process is very important to prolong the life of high-speed facilities. The data show that the highway guardrail is made of steel pipe and steel column processing and painting, and its surface coating is exposed to the atmosphere all year round. In the outdoors to withstand the sun exposure, rain and snow erosion, seasonal temperature changes and other media erosion, resulting in economic losses are very surprising.   Therefore, it is increasingly important to reduce the waste of resources caused by corrosion, improve the sustainable development ability of expressways, improve the safety, reliability, aesthetics and prolong the service life of steel components. The coating of the guardrail should not only resist corrosion and weather, but also have sufficient mechanical strength. Although the current anti-corrosion treatment technology, such as hot dip galvanizing, hot dip aluminum plating and other processes have been very popular, but with the progress of the era, the concept of "green, environmental protection" has gradually been recognized by people, people realize that the large-scale open hot dip plating is a kind of high energy consumption and high pollution industry. This eliminated the workshop process, and turned to the development of "environmental protection and energy saving" new technology. The electrostatic spraying process can effectively reduce the high temperature and heat loss required for molten zinc ingots and aluminum ingots. At the same time, the automatic spraying line of powder coating improves the product quality and efficiency, reduces carbon emissions, and has very important economic and social benefits for the construction of resource-saving and environment-friendly transportation. Therefore, powder coating is now used, that is, "epoxy zinc rich powder + polyester powder" process.   Powder coating not only has a good effect, its simple and generous design can also be naturally integrated into the landscape with the highway, reflecting the harmonious development of the road and the environment.

As we all know, in the process of powder coating, the powder is transported to the spray gun after fluidization through the air stream, the spray gun the electrode needle in the nozzle produces corona discharge with the high voltage electrostatic generator, and produces a dense negative charge near the electrode. When the powder is sprayed from the gun head, the charge is captured as a charged powder, which flies to the grounded workpiece under the action of the air stream, electric field and its own gravity,and adsorbed on the surface of the workpiece. Therefore, we need to take adequate preventive measures in the coating process. Metallic powder coating in most cases, use electrostatic spray gun , because this type of product contains metal pigments,should ensure that the system is well grounded, while setting a low electrostatic voltage and powder output, to prevent the occurrence of ignition during spraying. The effect of forming the film has a lot to do with the spray gun setting, quality or brand of the spray gun. After spraying for a long time, a large amount of metal powder may accumulate at the discharge needle of the spray gun, which needs to be cleaned regularly.   In most cases, due to the big tolerance, it is not recommended to use the gloss meter to measure the gloss of the metallic  film, and adopt visual comparison method to determine whether it is consistent with the standard template.   For the powder manufactured by the dry mixing method, due to the separation phenomenon in the spray and recovery process, there will be a certain difference in the metal pigment content of the recovered powder and the new powder, which may lead to the inconsistent coating film and the color difference. This is due to the difference of properties between metallic pigments and powder particles. It is recommended that the ratio of recycled powder to new powder at least 1:4. If the powder manufactured by the bonding fixation method, the recycled powder can be fully reused because the ratio between the metal pigment and the powder particles is relatively fixed.   The following advantages can be obtained by spraying the high glossy clear coating layer on the metallic powder film: enhance the rock impact resistance ,increase the aesthetic effect,completely solve the erasability of metal pigments,improve the weather resistance. In order to ensure the coating film appearance, it is required that the first time sprayed  workpiece can not be contaminated . Therefore, it is generally necessary to have a fully automated coating line and two sets of independent spray booths for separated coating. It is recommended not to spray the high glossy clear coating if you don’t have the equipment and conditions.   The following advantages can be obtained by spraying the high glossy clear coating layer on the metallic powder film: enhance the rock impact resistance ,increase the aesthetic effect,completely solve the erasability of metal pigments,improve the weather resistance.

With the development of powder coating, the gradual expansion of the scope of application of powder coating, powder coating has not been limited to the original type in the use , new color and variety are constantly introduced, some artistic powder coating gradually step into people's vision.   Transfer powder coating as a new type of arttistic powder coating, is the use of thermal transfer technology to transfer patterns such as wood grain through the transfer paper to the coating film, adjust the powder coating formula so that the ink on the transfer paper can easily penetrate into the coating film.   The transfer process has the advantages of green environmental protection, economic efficiency and excellent performance. With the improvement of people's environmental awareness, the application of powder coating is more and more popular. In particular, fine art texture powder coatings can obtain a variety of complex texture patterns at will, and are widely used.   Wood grain transfer profile refers to the rapid transfer and penetration of the wood grain pattern on the transfer paper or transfer film into the sprayed or electrophoretic profile on the basis of powder spraying or electrophoretic painting, according to the principle of high temperature heat penetration, by heating and pressurizing. So that the produced profile texture is clear, strong three-dimensional sense, can better reflect the natural feeling of wood grain, is an ideal energy-saving environmental protection material instead of traditional wood.   Transfer powder coating is divided into three categories, polyester powder coating, polyurethane powder coating and epoxy polyester hybrid powder coating, different types different  application ranges, product pattern vary according to customer preferences. In order to further improve customer visual experience, Fujian Wanan Group has specially launched a series of transfer powder coating.

  With the acceleration of urbanization, urban infrastructure construction is also constantly improving. Underground infrastructure pipelines such as water supply, drainage, gas, and heat are spread throughout the city like blood vessels in the human body.   Under natural conditions, pipelines that have been used for a long time will cause pipeline corrosion due to various factors such as dirt accumulation, water infiltration, and sand wear, resulting in pipeline rupture and leakage, damaging the structural strength and transmission efficiency of the pipeline, and adversely affecting the lives of urban residents. bring inconvenience.     According to statistics, the annual economic losses caused by corrosion account for about 3%-4% of the country's total economy (data source: Academician Xu Kuangdi, Honorary Chairman of the Presidium of the Chinese Academy of Engineering). Paint coating is one of the most basic methods of pipeline anti-corrosion.   The underground environment is dark, humid, complex and changeable, and there are many factors that cause corrosion of the outer wall of pipelines, including acids, alkalis, salts, oxidants, water vapor, etc. The coating of Wanan anti-corrosion powder coating has excellent resistance to chemical corrosion, acid and alkali resistance, and salt spray resistance. It has been proved by the cathodic peeling resistance test (test method: SY/T 0315-2013 Appendix C). The coating of Wanan anti-corrosion powder coating The peeling diameter of the coating is 13.8mm, which meets the technical specifications (≤15mm). In complex and changeable environments, the coating can be maintained for a long time without discoloration, swelling, softening, skin explosion, cracking, peeling, etc. In complex geological environments , can effectively isolate the pipeline base material from the corrosive medium and provide long-term anti-corrosion protection for the outer wall of the pipeline.     During long-term transportation and use, scaling will inevitably occur on the inner wall of the pipeline. These substances will promote and intensify the corrosion reaction in the pipeline, affect the pipeline transportation efficiency and even contaminate the transportation medium.   Wanan anti-corrosion powder coating has excellent chemical stability and can resist the erosion of a variety of chemical substances. The product is non-toxic, has no solvent pollution, no VOC emissions, and zero formaldehyde pollution. It will not breed bacteria and other harmful chemicals to pollute the transportation medium in the pipeline. , the coating has strong adhesion and dense structure, and the surface is flat and smooth, which can effectively inhibit scaling in the pipe, improve the medium transportation capacity, and provide a comprehensive anti-corrosion "barrier" for the pipeline from the inside to the outside.       Our country has a vast territory, complex and changeable topography, and great differences in water and soil resources and climate conditions in different regions. Affected by the complex underground environment, pipelines that have been used for a long time may have structural problems such as deformation, subsidence, misalignment, and disconnection, which will accelerate pipeline corrosion and aging and affect their service life.   Wanan anti-corrosion powder coating has excellent properties such as high adhesion, strong hardness, good flexibility, and scratch resistance. Experimental tests have proven that the pipe samples coated with Wanan anti-corrosion powder coating after being flattened 4/5 (i.e., flattened pipe to four-fifths of the outer diameter), the coating has no cracks or peeling, meets CJ/T 120 testing standards, and can provide strong protection for coated pipelines, effectively preventing pipeline rupture, media contamination, etc. caused by deformation and wear. Security risks.     Wanan Group takes "providing one-stop painting solutions and continuously creating maximum value for customers" as its corporate mission.

Powder coatings have a number of advantages, which is why they are considered a top choice for industrial finishes. In addition to their legendary durability, they have other strong points that may not be immediately obvious or initially considered when choosing a finish.   Environmentally Friendly   Powder coating is one of the most ecologically friendly options available. The powder is often reusable and recyclable, especially when it comes to thermoplastics. This type of powder coating can be reshaped much more easily than thermosets.  The powder also is less likely to be wasted with this type of finish. When it comes to others, like paint, overspray is common, and as much as 70% of the paint can be wasted that way. Powder coatings tend to waste 5% or less in comparison. Powder coatings do not require solvents in the same way paints do, and they release very little volatile organic compounds (VOCs) that can be harmful to the environment.   Safe Option   In addition to being environmentally safe, they are also one of the most personally safe options. While it is still important to wear the necessary personal protective equipment (PPE), powder coating does not pose as much health risk even as paint. This is in part due to the lack of VOCs, which can cause respiratory problems.   Polished Look   Powder coating makes it easier to maintain a polished shine on equipment and even simple household items. Because it repels moisture, chemicals, and other harmful materials, it is also easier to clean. Reducing cleaning time means increasing efficiency when it comes to production or attentiveness to other matters in a facility. Consistently attractive and cared for parts do not only add to functionality (though that is the main advantage in this case)—they also give a positive impression. Anyone who enters the area will notice that the facility is kept clean, which goes a long way in any industry.   Budget-Friendly   While the upfront investment can seem overwhelming, the cost over time of powder coating is lower than most finishes. It requires fewer materials and less equipment than more specialized finishes, and the low waste production means waste removal costs are lower as well.

  The powder coating process requires some specialized equipment. The powder used can be one of two types: thermoplastic or thermoset. Thermoplastic powder becomes softer and more liquid when heated. In this case, there is no chemical bonding, which makes this form of powder coating reversible and reusable. Thermoplastic coatings are thicker and more durable than thermoset coatings, and for this reason, they are used on everything from refrigerators to auto parts to metal fencing.   Thermoset powder coatings work a little differently. They form chemical bonds when cured, which means they cannot be recycled in the same way thermoplastics can. They are ideal for high heat areas, as these bonds make them unlikely to melt away as thermoplastics would in the same situations. Thermoset coatings are often the cheaper of the two.   Once the type of coating is decided, the first step in the powder coating process is preparation. This is perhaps the most important part of any project, as it will determine how well the powder coating adheres to the surface it is intended to protect. Preparation can involve sandblasting as well as using a primer before applying the powder coating.   Powder coatings are usually applied using an electrostatic gun, which charges the powder before it is sprayed onto a surface. Then, the powder is sprayed onto the desired surface using compressed air. After the powder has coated the object’s surface, curing can begin, during which time the surface is heated to allow the powder to melt and form a film. Once it cools, the coating hardens, and the process is complete.   There are other methods of applying powder coatings, though they can be problematic or are only suitable for certain types of projects. For example, a metal surface may be heated prior to applying the coating, which allows the powder to melt on contact. The problem here is that it may cause excess powder to run, which creates more work and may require the process to be redone. Electrostatic fluidized bed coating is another method of powder coating and is a dipping process that cannot be used on larger pieces.
