  With the development of social economy, people's pursuit of high-quality life concept has penetrated into the steel industry, and   colorful and functional color-coated steel plates   have emerged as the times require.   Color-coated steel plate is an organic coating applied to the surface of the steel. It has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, and convenient processing. Color-coated steel plate is also called pre-coated steel plate. The metal coil (cold-rolled sheet, hot-dip galvanized sheet, aluminized sheet, high aluminum alloy sheet, stainless steel sheet, etc.) is used as the base material, and various organic coatings or plastic films are coated or laminated on the surface.   Classification of color-coated boards The color-coated sheet has the advantages of both organic polymers and steel sheets, including good colorability, formability, corrosion resistance, decorative properties, and high str...

  First, chromating Chroming will form a chemical conversion film on the surface of the product, the thickness of the film is 0.5-4um, this conversion film has good adsorption, mainly as a coating base layer. The appearance is golden yellow, aluminum color, green, etc. This conversion film has good electrical conductivity and is the best option for electronic products, such as conductive strips in cell phone batteries, magnetic devices, etc. The film is suitable for all aluminum and aluminum alloy products. However, the conversion film is soft and not wear-resistant, so it is not conducive to be used as external parts of products.   Second, anodic oxidation Anodic oxidation: It can make the product surface form a uniform and dense oxide layer, and this film can make the surface hardness of the product reach 200-300HV. In addition, this product has very good wear resistance, and can be used as a mandatory process for aviation and aerospace related products. The difference betwe...

  Aluminum is a material widely used in the production of automobiles, aircraft, panels, construction and packaging components. In addition, aluminum can be coated with different substances or paints to increase its durability and attractiveness and to make it more durable. There is a wide range of  aluminum coatings  that were created according to the needs of customers and market trends. In fact, by surface coating we are not only referring to the industrial process of applying a coating on ACP. There are two main reasons for selecting a specific type of coating: to protect the material being coated and to improve its aesthetic and functional properties. For this reason, the type of coating varies depending on the end goal and the application area.   TZ1600-40 Double Sides & Double Coatings Line   Aluminum coil pretreatment The surface of the coil is cleaned of oil and impurities by means of chemical cleaning agents and chemical conversion solvents, so tha...

  Powder coating has many advantages and disadvantages as a metal finish. It is often chosen for its durable finish, environmental friendliness and lower variable cost compared to liquid coatings. However, even powder coatings are susceptible to wear and damage over time. Whether it is to prevent oxidation of the iron substrate or to restore the appearance of the product, there is a good reason to apply a  liquid coating  to a powder coated surface. If you want to continue painting, the short answer is yes, however, you must be aware of some precautions.     Challenges of applying spray paint Adhesion - Adhesion is the ability of a coating to bond to a specific surface. The challenge with adhesion when applying paint over powder coatings is that powder coatings can often produce a very flat, smooth surface. This can present a challenge when trying to get a liquid coating to bond properly to the substrate underneath. Matching coating properties - Powder coat...

  Coil coating line   is an automated and efficient method of coating metals. It is a continuous process that requires a roll of metal for each finishing step from cleaning to curing before packaging for shipping. Coil coating provides a consistently high quality product that is durable, corrosion resistant, cost effective, recyclable and more environmentally friendly than other alternatives. In this article, we will learn about the coil coating process, the different coating technologies used for coil coating.   Main steps The coil coating process starts with a coil of untreated sheet metal that is unrolled, treated, coated, cured, rewound and packaged for shipping at a rate of 100-200 meters per minute. This process can be used on one or both sides of the sheet metal and up to three layers of paint can be applied and cured. Sheet metal is most commonly aluminum, steel or galvanized steel, with varying coil sizes. The coil coating process is shown below. Stitching the st...
