  Painting  is an important part of the surface manufacturing process of construction machinery products. Anti-rust, corrosion prevention coating quality is one of the important aspects of the overall quality of the product. Product appearance quality not only reflects the product protection, decorative performance, but also constitute an important factor in the value of the product. Construction machinery anti-rust coating process can be generally divided into surface treatment process before coating and anti-rust primer  coating process.  LITONG  shows you. 1、Surface treatment Surface treatment is one of the important processes of anti-rust coating. The quality of anti-rust coating of construction machinery depends largely on the way of surface treatment. Coating life is governed by 3 factors: surface treatment; coating construction; quality of the coating itself. Mechanical cleaning can effectively remove the rust, welding slag, oxide skin on the workpiece, e...

  Paint/coating application in the coil coating process follows the pretreatment process and the coating process consists of two stages, namely primer application and topcoat application. The painting process is also divided into various kinds, and the paint curing methods are different for each of them.   LITONG,   as a professional coating line supplier, we are happy to introduce you the knowledge about it.   Coil coating line 1, with a single coater and oven. These lines serve a market primarily oriented towards consumer products, consisting of cold rolled steel (CRS), tinned mill black plate (TMBP) and/or tin-free steel (TFS). Although product availability is limited, these lines offer significant cost advantages over lines running two or more coaters and ovens on a single line. 2, lines with two or more coaters are called tandem lines, and they are capable of applying primer and topcoat in a single pass. These lines primarily serve the construction and appl...

  Although the pre-painted metal process has been around for years, some misconceptions about the process still exist. LITONG, a manufacturer of   aluminum coating lines,   explains the benefits of coating and the misconceptions people have about it.   Misconception 1:Outsourcing increases costs Like most manufacturers, companies often have to adapt their paint shops to changing environmental standards, strict health regulations and increasing overhead. Companies are struggling to reduce costs and remain competitive. Outsourcing metal handling and coating operations can mitigate or even eliminate these costs. One suggestion is to create a pre-paint conversion team of internal and external managers and suppliers to analyze the product and process to determine if pre-paint conversion is feasible. Once the conversion process is complete, the plant will run more efficiently, effectively and economically. Converting to color coated metal can improve your product and profi...

  Roll coating   is a metal finishing process. It has the advantages of good temperature resistance, environmental friendliness, long-lasting and constant, and sturdiness. The aluminum sheet after the roll coating process is called roll-coated aluminum sheet. Roll-coated aluminum sheet is made by degreasing and chemical treatment on the surface of aluminum sheet as a base material, and then roll-coated with high quality paint and dried and cured. Roll-coated aluminum sheet is made of the same material as the laminate. Through the high-performance roller coating process, it can more effectively control the precision and flatness of the sheet, and make the architectural decoration color uniform and delicate, soft and bright.   TZ1600-35 2-Sides 2-Coatings Production Line (Integrated)   Advantages 1. Good temperature resistance, the melting point of aluminum is 660 degrees, the general temperature can not reach its melting point. 2. Strong environmental protection, not ...

  Coating is one of the most critical processes in the entire aluminium coil   coating production line . The quality of the coated product, especially the quality of the appearance, directly affects the decorative effect of the product. Therefore, it is important to first get to grips with the common defects in the coating process and the reasons for their formation. The reasons for the formation of defects are manifold, and  LITONG  analyses them for you as follows.   1、Raw material paint, and aluminium coil, is the biggest factor affecting the quality of coating, if there are the following problems: colour difference between paint batches, insufficient paint fineness, low coating rate, poor paint and solvent cooperation, delamination, etc., they will directly affect the coating effect and produce defects, resulting in uneven aluminium coil substrate, uneven film thickness, poor edge deflection. It will also directly affect the product quality and overall use. ...
