答:彩涂板涂敷工艺主要有辊涂法、层压贴膜法及粉涂法三种。 辊涂工艺:是利用旋转的粘料辊和涂敷辊将液态涂料均匀、连续地涂敷在基板 下表面,经烘烤固化而成。世界上采用这种类型工艺的机组数量最多,生产量最大,并积累 了大量成熟生产操作经验。产品应用也最普遍,其产品广泛应用在室外建筑,也应 在室内装潢、家电、家具等领域。这类机组的运行速度较高、单机产能大。 辊涂工艺具有生产灵活、涂料适应性强、涂层厚度范围大等优点;采用辊涂工 艺过配置涂后处理的专门设备(如层压机和压花机等)即可生产出层压和压花产品。 层压贴膜工艺:是将塑胶膜用热固粘结剂压粘在钢板表面,产品可保持塑胶膜原有 色泽,膜与基板不易剥离,适合再加工。这种产品外观醒目、具有防火、耐蚀、抗酸等能; 其耐火性、抗污染性较好。产品主要应用于家电、家具、室内装潢及车船内部装 目前其产品虽有增长势头,但采用此工艺的机组生产规模小,一般为专业家电板厂 用,也有一些的彩涂机组是辊涂与层压贴膜两用机组。 粉涂工艺:是一种近年开发的新工艺,分为粉末枪及粉末云两种技术。几年前世界 就有多套采用粉末枪技术的彩涂机组投产,但其机组速度低、生产能力小。最近开为 MSC 粉末云技术使粉涂机组的效率大为提高,粉末涂料的沉积率达 90%,已投产的析 速度已达 100m/min,钢带宽度达 1300mm。该技术采用粉末涂料,粉涂装置在强大的 场下,粉末旋转刷产生涂料粉末云,并带电荷飞向基板,沉积在钢带表面,再经感应加 固化,生产出粉涂彩涂板 目前国内大部分机组都采用辊涂工艺,辊涂型机组主要有一涂一烘、二涂二烘和三 三烘三种生产工艺形式,其中二涂二烘工艺应用最普遍,它具有生产灵活、产品范围 适应能力强、投资适中等特点。
Answer: The coating technology of color coated plate mainly includes roll coating, laminating film coating and powder coating. Roller coating process: The liquid coating is uniformly and continuously coated on the bottom surface of the substrate by rotating adhesive rollers and coating rollers, and cured by baking. In the world, the number of units adopting this type of technology is the largest, and the production capacity is the largest, and a large number of mature production and operation experience has been accumulated. Product application is also the most common, its products are widely used in outdoor buildings, but also in interior decoration, household appliances, furniture and other fields. This kind of unit has high running speed and large single unit capacity. Roller coating process has the advantages of flexible production, strong adaptability of coatings and wide thickness range of coatings. The laminating and embossing products can be produced by using special equipment (such as laminator and embossing machine) equipped with roller coating process after coating treatment. Laminating process: the plastic film is bonded to the surface of steel plate with thermosetting binder. The product can maintain the original color of plastic film. The film and the base plate are not easy to peel off, so it is suitable for reprocessing. This product has a striking appearance, fire protection, corrosion resistance, acid resistance, etc. Its fire resistance and pollution resistance are good. The products are mainly used in household appliances, furniture, interior decoration and interior decoration of vehicles and ships. At present, although there is a growing momentum, the production scale of the units using this technology is small, generally for professional household appliances board factory, and some color coating units are roll coating and laminating film dual-purpose units. Powder coating process: is a new process developed in recent years, which is divided into powder gun and powder cloud technology. A few years ago, a number of color painting units using powder gun technology were put into operation in the world, but their speed is low and their production capacity is small. Recently, MSC powder cloud technology has greatly improved the efficiency of powder coating unit. The deposition rate of powder coatings reaches 90%, the precipitation rate of powder coatings has reached 100 m/min, and the steel bandwidth has reached 1300 mm. Powder coating is used in this technology. Powder rotating brush produces powder cloud of paint under strong field, and charges fly to the substrate, deposit on the surface of steel strip, and then strengthen by induction. At present, most of the domestic units adopt roll coating technology. Roller coating units mainly have one coating, one baking and two coating. Baking and three-three-baking are three kinds of production processes, of which the two-coat and two-baking process is the most widely used. It has the characteristics of flexible production, strong product range adaptability and moderate investment.
