The inductance does not meet the expected value. You can investigate from the following aspects. First, check if the magnetic ring selection is correct. Different specifications of magnetic rings are suitable for different application scenarios, and the inductance design value is also different. If the selection is correct, then check the winding method and number of turns. Insufficient turns or loose winding will reduce the inductance. In addition, whether there is physical damage to the magnetic ring, such as cracks, notches, etc., can also affect the inductance performance. If there are no issues with the above aspects, it may be due to inaccurate measuring instruments or improper measurement methods. You can gradually investigate in this order, and if it still cannot be resolved, you can contact our technical support personnel.

Our magnetic ring products have been specially designed and processed to have good temperature and moisture resistance. In general high temperature and high humidity environments (temperature 85 ℃, relative humidity 85%), short-term use (such as 1-2 weeks), the performance is basically not affected. But if exposed to this environment for a long time, there may be a slight decrease in magnetic permeability, aging of surface coatings, and other factors that can affect the overall performance of the magnetic ring. However, by choosing appropriate protective measures such as adding sealed enclosures and implementing moisture-proof treatments, the service life of magnetic rings can be effectively extended in harsh environments.

There may be multiple reasons for insufficient hardness of the paint film. Firstly, it may be due to incomplete curing, as the curing temperature and time did not meet the product requirements. Our rotor paint generally recommends a curing temperature of 120 ℃ -150 ℃ and a curing time of 2-4 hours, which can be adjusted according to the actual situation. Secondly, excessive addition of diluent changes the formula ratio of the paint and affects the performance of the paint film. Furthermore, the construction environment is too humid, and in high humidity environments (relative humidity exceeding 70%), it may cause the paint film to absorb moisture during the drying process, affecting its hardness. You can check the curing conditions, diluent dosage, and environmental humidity. If you have any questions, please feel free to communicate with us at any time.

The poor leveling performance of thermosetting powder coatings during construction may be due to low construction temperatures. It is generally recommended that the construction environment temperature be between 18 ℃ and 25 ℃. Low temperatures can increase the melting viscosity of the coating, affecting leveling. The distance between the spray gun and the workpiece is too far or the spraying pressure is not appropriate, which can also cause poor leveling. The normal distance between the spray gun and the workpiece should be 15-20cm, and the spraying pressure should be maintained at 0.3-0.5MPa. Also, quality issues with the coating itself, such as uneven particle size distribution, may also cause this problem. You can adjust the construction temperature and spray gun parameters first. If the problem persists, you can contact us and we will investigate the quality of the coating.

Coating detachment may be caused by the following reasons. One reason is that the surface treatment of electronic components is not in place before spraying, such as oil stains, dust, rust, etc., which affects the adhesion between the coating and the substrate. Secondly, during the spraying process, the process parameters were set unreasonably, such as spraying pressure, spray gun distance, spraying thickness, etc., which did not meet the requirements. In addition, if the processed product is subjected to frequent mechanical friction, chemical corrosion, or drastic temperature changes during use, it may also cause the coating to peel off. You can first check the surface treatment and spraying process of the product. If it still cannot be solved, you can send the relevant product back and we will conduct detailed testing and analysis.

Our anti-interference magnetic ring has good suppression effects on interference of different frequencies, but the emphasis is different. For high-frequency interference (generally referring to frequencies above 1MHz), magnetic rings utilize their high impedance characteristics to convert high-frequency currents into heat energy and effectively suppress the transmission of high-frequency interference signals. For low-frequency interference (usually in the range of 1kHz to 1MHz), magnetic rings mainly reduce the impact of low-frequency interference by changing the path of the interference current, so that the magnetic fields formed by them cancel each other out. Overall, significant anti-interference effects can be achieved within their respective frequency ranges of expertise.
