Fluorocarbon coating plate (1) coated with a fluorocarbon coating plate is divided into two systems, three-coat system and four-coat system, generally should adopt a multi-layer coating system. Two coating system: 5 ~ 10μm fluorocarbon paint and fluorocarbon finish 20 ~ 30μm consisting Hebei scrap metal recycling, the total thickness of the film is generally not aluminum staircase stretcher should be less than 35μm. Only be used for the general environment. Three-coat system: 5 ~ 10μm of fluorocarbon primer, 20 ~ 30μm fluorocarbon paint and varnish 10 ~ 20μm fluorocarbon composition Henan scrap metal recycling, the total film thickness not less than 45μm. For air pollution, industrial areas and coastal and other harsh environment areas. Four coating systems: Four coating system has two. One is when using large particle aluminum pigments, required between a primer and topcoat additional intermediate fluorocarbon paint 20μm; the other is added between the primer and paint together polyamide and polyurethane blends dense coating to improve the corrosion resistance, increasing the life of fluorocarbon aluminum. Because most of the fluorocarbon is a sponge structure scrap metal recycling, there are holes, can not prevent the free positive and negative ions in the air to penetrate to the metal plate substrate. Therefore, this coating system is more suitable for air pollution, poor industrial areas and coastal zone environment. (2) fluorocarbon paint cure: there should be a few painted on a few grilled Hunan scrap metal recycling, so that each paint is fully cured, form a good adhesion, corrosion resistance, fade resistance, avoid multi-coated little roast. (3) In the selection of fluorocarbon paint aluminum, should concern fluorocarbon brand and the major technical indicators, and the fluorine resin content should be ≥ 70%. Secondary wrought aluminum alloy: 2000 series aluminum representatives 2024,2A16 (LY16), 2A02 (LY6). 2000 series aluminum is characterized by high hardness, which the copper content, probably in about 3-5%. 2000 series aluminum rod is aviation aluminum in conventional industrial infrequent application. Three Lines: 3000 series aluminum alloy on behalf of 3003, 3A21 based. Our 3000 series aluminum production process is relatively good. 3000 series aluminum rod is composed of manganese as a main ingredient. Content is between 1.0-1.5, is a rust-proof function better. Aircraft four lines: 4000 series aluminum bar representatives 4A01 4000 series aluminum is higher silicon content. Usually silicon content of 4.5-6.0%. Are used in construction materials, machinery parts, forging materials, welding materials; low melting point, good corrosion resistance, the product description: with heat and wear characteristics of scrap metal recycling, scrap metal recycling Shengxin Hebei scrap metal is recovered from the Linyi City Sheng Xin scrap metal recycling Limited. Scrap metal recycling, Shengxin scrap metal recycling, scrap metal recycling Hebei Linyi City Shengxin scrap metal recycling Ltd. (shengxin.tz1288.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image on the telephone, to obtain the latest information, contact: Zhu new.
