1. The impact action of high-pressure water jet (plus the grinding action of abrasive) and water prying action are used to destroy the adhesion of corrosion and coating to shelf steel plate. It is characterized by no dust pollution, no damage to the shelf steel plate, greatly improving the derusting efficiency, up to more than 15m2 / h, and good derusting quality. However, the shelf steel plate after derusting is easy to rust back, so it must be coated with a special wet derusting coating, which has a great impact on the coating of general performance coatings.Shopping Trolley manufacturer

   
   

2. The rusty part can be scrubbed with hydrochloric acid, and then painted with paint after the rust is washed off. It should be noted that the rusty Dongguan shelf should not be soaked in dilute hydrochloric acid for too long, otherwise the substances inside will react after removing the surface rust.Shopping Trolley manufacturer

3. Chemical derusting is mainly a derusting method that uses the chemical reaction between acid and metal oxide to remove the rust products on the metal surface of shelf materials, that is, the so-called pickling derusting can only be done in the workshop.Shopping Trolley manufacturer
