Coating Thickness Tester Test the Copper Sheet Resin Powder Coating Thickness
The resin powder has good physical and mechanical properties as well as electrical insulation.It is usually used on copper sheets.In addition to its excellent adhesion to other materials, this powdered resin is also not available in other materials due to its flexibility and thermoset properties. Since the resin powder coating contains an active epoxy group in the molecular structure chain, it cross-links with other curing agents to form insoluble.
This resin powder coating is usually used on copper bars (also known as busbar), which are mainly used on primary lines.Copper lines are used for phase lines, neutral lines and ground lines of high current.For example,a row of electrical cabinets connected between the cabinet is a busbar.The switchgear that is divided between the main busbar and each of the electrical cabinets is a denominator row.
The copper bars are tinned and bare copper.They are also insulated and painted.The reason why the resin powder coating is selected is a little more because the powder coating is uniformly applied to the surface of the copper row by a plastic coating process. After curing, a flat, smooth and strong protective layer is formed on the surface.The copper row is made into a composite product.This method not only maintains the original strength and rigidity of the busbar,but also has the advantages of anti-corrosion, smoothness and wear resistance of the plastic coating,thereby prolonging the service life of the copper row.
The thickness of the copper-plated resin powder coating is required to be 0.5 mm, because if the coating is too thick,the performance of the copper-plated surface layer may be affected. The coating is too thin to achieve insulation and protection. Long use time may cause a short circuit.Therefore,we usually use the Linshang LS220H coating thickness tester to check the resin powder coating thickness on the copper sheet.
The Linshang LS220H coating thickness tester uses two measurement principles: magnetic thickness measurement and eddy current thickness measurement to measure non-magnetic coatings on magnetic metal substrates.Such as plastic, resin powder, paint, enamel, etc.,It can also measure the thickness of the non-conductive coating on the non-magnetic metal substrate, such as anodizing.
The Linshang LS220H coating thickness tester not only has a wide measuring range,but also has a good after-sales service. Let you have no worries after sale.
The goods can be return without any reason in 30 days (Can be used for second sales).
The warranty period of the instrument is one year. If the instrument fails within one year, the instrument can be sent to the company for repair.
