What is the main difference between shot blasting machine and sand blasting machine Shot blasting is the use of high-speed rotation of the impeller to small steel or iron shot thrown out of the high-speed impact on the surface of the parts, so you can remove the oxidation layer on the surface of t
Aluminum surface treatment process discussion Metal materials are increasingly used in various products, because metal materials can better reflect the quality of products and highlight the brand value. (to form a satin-like effect), electroplating (covered with a layer of other metals), spraying (covered with other non-metallic coatings) 1. Sandblasting (shot blasting) The process of cleaning and roughening the me
Surface particles in the process of powder coating of aluminum profiles At present, anodic oxidation, electrophoretic coating and powder coating are one of the three main surface treatment methods for aluminum profiles, each of which has its own advantages and occupies a considerable market share respectively. Powder spraying uses powder coating, and the process adopts electrostatic spraying, using the friction gun to make the powder particles carry a positive charge when spraye
Powder coating of aluminum profiles spraying three elements Powder coating for aluminum profiles is used, the process is electrostatic spraying, the use of abrasive spray gun, under the influence of accelerating wind, so that the powder particles sprayed out of the gun body when carrying a positive charge, and negatively charged profiles in contact with the electrostatic adsorption, and then after high temperature curing. It also enhances the adsorption strength of the coating, a
Detailed introduction of sandblasting rust removal technology knowledge General knowledge of sandblasting rust removal Sandblasting to remove rust is to use compressed air as the power to form a high-speed jet beam to spray material (copper ore, quartz sand, diamond sand, iron sand, Hainan sand) at high speed to the surface of the workpiece to be treated, so that the appearance or shape of the outer surface of the workpiece surface
Application range of sandblasting machine I. Pretreatment. Plating, painting, spraying and all covered processing before sandblasting treatment, the surface is absolutely clean, while greatly improving the coverage had adhesion and corrosion resistance. Second, cleaning. Casting parts, stamping parts, welding parts, heat treatment parts and other metal workpieces to oxide,
Introduction to the three major systems of spraying and painting Solvent-based coatings contain solvents, which emit a large amount of VOC (Volatile Organic Compounds) during the production and construction process, endangering human health and causing environmental pollution. According to statistics, the global annual VOC emissions to the atmosphere are up to several million tons. VOC is a major pollutant in the paint shop, including benzene, styrene, formalde
How to improve the leveling of powder coatings? Powder coating is a new type of solvent-free 100% solid powder coating. It has two major categories: thermoplastic powder coatings and thermosetting powder coatings. The coatings are made of resin, color filler, curing agent and other additives, mixed in a certain ratio, and then prepared by the process of hot extrusion and crushing through the sieve. They are at room temperature, storage stability, by electrostatic spraying or flui
How to choose the different types of phosphating process According to the operating temperature, can be divided into high-temperature phosphating, medium-temperature phosphating, low-temperature phosphating. 1) low-temperature phosphating, at room temperature, long processing time, in addition to medium-temperature phosphating has been added to the composition, in order to accelerate the speed of phosphating, but also add fluoride, the advantage of low-temperature wor
