First, what should be paid attention to in the use of color coating rolls? Most people in the early paid great attention to the
prepainted color galvanized coil price, buy painted coil is used directly after the regardless of right to use, but can be how many people will notice it in use is also have many points need to pay attention to, reasonable to apply the attention points, not only can avoid some unnecessary loss, but also can greatly prolong the service life of it, the following simple understanding about action volume in use need to be aware of what time.
Second, about the useful raw materials in the operation process cannot ignore the relevant details of the question, first of all, must lead to the attention of every staff, so as to more useful to improve the availability of the raw materials, then in the following to know.
1. Not the same price of color coating volume finish varieties in hardness, patience, adhesion, durability and other aspects of the difference. Polyester is the current application of the largest amount of paint, durability in general, good hardness and patience, moderate price. Silicone modified polyester has high durability, luster and color persistence, but slightly reduced tolerance, and high weathering polyester is of high-cost performance. Polyvinylidene fluoride durability, patience, but low hardness, available for less color, high price. The top paint of the painted board is primarily based on the use, use of environmental corrosion, service life, durability, processing methods, deformation degree.
2. Not the same price of prepainted color galvanized coil primer adhesion, patience, corrosion resistance must be different. Excellent adhesion between epoxy and substrate, high corrosion resistance, but not as resistant as other primers. Polyester with good bonding force, excellent resistance, but corrosion resistance than epoxy. Polyurethane is a good overall primer. Primers are generally selected by the supplier in accordance with the production process, use, use of environmental corrosion, and topcoat matching.
3. Corrosion resistance generally increases with the addition of coating thickness, order should be based on the corrosive environment, service life, durability, and other factors to determine the coating thickness.
Third, from the above explanation is not difficult to see, about the application of color coating material details question, this is particularly important, how to have other questions about color coating can be directed to our website for a free consultation.
