Scratch test is mainly used for color-coated scratch-resistant coating insulation performance assessment. Test instrument from scratch to take advantage of a certain weight must load slowly moving the needle in color-coated surface of the coating, if the coating color steel needle plow breaking volume, will be displayed between the needle and the conductive plate or strip. To plow under a certain weight is broken needle coating maximum load to assess the performance of color-coated scratch-resistant coating. Scratch tests are usually two ways to define scratch resistance coatings sales volume Color color plates, one method is to determine whether it is fixed by the next load. Another method is to gradually increase the weight of the weight of the load tests were repeated. Not until you find broken plow maximum weight coating weight. The former method is to have at least three experiments to test the results of the two tests by Color color steel coil prices, the latter method places the arithmetic average of the three different parts of the maximum weight load of the test results. Each steel material requires relatively specialized maintenance methods to ensure a good application, particularly related products often used in daily operations, took the first color plate material, because the product occupies a more important applications in daily use sex, so professional maintenance methods is very important, so today in this following we take a look at. Color plate housing will be built because of the different environments in different houses. To expand the living space, activity room privacy requirements of high economic level can opt for the construction of a low roof insulation panels, plastic windows for added insulation wall surrounding maintenance products. Sun room of such products, though not in the strict sense, but the low price, economical and practical. The disadvantage is poor lighting and ventilation in general. As an additional skylight will have greatly improved. But if you build color plate activity room mainly for winter flowers and grass, then you need proper sunlight and ventilation, should use a glass roof and opened a large skylight color plate activity room. If you have a large area of ??housing, especially villa building, your color plate activity room is mainly used for winter recreation, fitness, gardening, etc., should choose a roof that opens a whole can move the mobile color plate activity room. If you need a traditional architectural features color plates activities room, should choose steel hollow glass roof, and with the right amount of special hollow glass skylights to bridge hollow aluminum or aluminum composite wood windows made of hollow glass windows surrounding the maintenance of the product. So a variety of color plate housing maintenance needs in different ways.
