Linqu San Ye Metal (www.shengyehl.com) is located in Weifang, Shandong Province Linqu Temple head cartridges Lu Industrial Park, Contact: WANG Zhao-xiang powder coating process galvanized fence: 1 is the powder coating. give full play to the characteristics and extend the service life of the coating, coated on the surface first to break the strict surface pre-treatment. 2 When spraying, be coated must be fully grounded in order to increase the efficiency of puffing powder coating. 3 has a larger surface to be coated defects should Scraping conductive putty, to ensure smooth and smooth feel coating. 4 After spraying objects objects need to be heat-curing, curing conditions prevail powder product cost technical indicators, but must fully guarantee the curing temperature and time, causing the foot to avoid curing quality accident. 5 spray immediately after inspection, if found defective should be promptly treated Shandong galvanized fence, if found defective after curing, a small range without affecting only partially galvanized fence was painted surface decoration, available same color powder diluted with acetone to repair, if they affect the surface quality range, use the sanding galvanized fence processing, then spray with a paint remover to remove the coating or galvanized guardrail sales again Re Suo powder. 6 After recovering powder to be screened to remove debris, new powder mixing with a certain proportion. Hydrochloric acid pickling method is rust on galvanized fence companies adopted. Therefore, hydrochloric acid is widely used raw material is. Mass fraction is often controlled in the range of 5% -15%. The lower the mass fraction of the acid, the longer the time for pickling galvanized guardrail needed. The temperature is usually pickling, the pickling speed of impact. Further, when the pickling galvanized fence, iron deposition will continue in the tank. When the iron reaches 150-200g / L, the quality although a tank containing an acid pickling rate, but much slower. In the case without rust agent, usually disposed of in its entirety.
