High Adhesion 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. While attaching great importance to research and development, it also attaches great importance to product safety, reliability and quality stability.     The Wanan Testing Center officially established a laboratory management system and operates it effectively in September 2019. It officially passed the CNAS laboratory accreditation certificate in 2021, marking that the Wanan Testing Center has nationally and internationally recognized management levels and testing capabilities. It also provides The quality assurance of Wanan anti-corrosion powder coating products provides stronger technical support.     In January 2022, Wanan Group's corporate standard Q/WA 04-2021 "Epoxy Anticorrosive Powder Coating for Drinking Water" was evaluated by the China Coatings Industry Association and won the title of "Leader" in corporate standards, highlighting the market and industry's recognition of Wanan Anticorrosion Highly recognized for powder coating products.
