压层彩钢板的特点是什么

层压彩钢板是彩钢板除压纹钢板外的另一种产品。层压彩钢板是在钢板上预先涂上胶粘剂，在一定温度下轧制（图1-13）并在钢板表面复合塑料膜而成。其生产工艺是将基材清洗、化学涂布后，用精涂机在基材的下表面涂背漆，在上表面涂粘合剂。背漆在固化炉中烘烤，同时固化，粘合剂被激活。固化炉出口设有覆膜机，覆膜辊将有机膜压在基材表面，粘结剂经水冷固化，使有机膜与基材上表面粘结牢固。 层压彩钢板常用的有机薄膜也叫层压板，基材通常是乙烯基薄膜（PVC）、氟树脂覆膜仓、快烘小膜仓（PVF）、聚偏氟乙烯（PVDF）、聚酯树脂覆膜（PET）、丙烯酸树脂覆膜（PM-3计划，姓苏国马）等。

层压材料耐潮湿和水。
层压板的生产成本较低。它具有钢板的强度和塑料的耐腐蚀性。另外，由于塑料薄膜具有多种花纹和图案，其装饰性能比涂布板更强。塑料在生产过程中还可以含有多种添加剂，使层压板获得许多普通涂布板不具备的成品性能，如弯曲、冲压和折叠。另外，塑料薄膜较致密，吸水性和渗透性较差，因此具有很强的耐腐蚀性。作为一种新型的复合材料，它越来越受到人们的重视。

Laminated color steel plate is another product of color steel plate except embossed plate. It is made by coating adhesive on steel plate in advance, rolling (Fig. 1-13) and laminating plastic film on steel plate surface under certain temperature. The production process is that after the substrate is cleaned and chemically coated, the back paint is applied on the lower surface of the substrate by the fine coating machine, and the binder is applied on the upper surface. The back paint is baked in the curing furnace and solidified at the same time, the binder is activated. A laminating plastic film machine is set at the outlet of the curing furnace, and the laminating roller presses the organic film onto the surface of the substrate, and the binder is solidified after water cooling to make the organic film firm Bonding to the upper surface of the substrate. Laminate commonly used organic film is also called laminate, the substrate is usually vinyl film (PVC), fluoro resin coated warehouse, fast baking warehouse with small film (PVF), polyvinylidene fluoride (PVDF), polyester resin coating (PET), acrylic resin coating (PM-3 plan, surnamed Su Guo MA), etc.

The laminate is resistant to moisture and water.
The production cost of laminate is low. It has the strength of steel plate and the corrosion resistance of plastic. In addition, because the plastic film has a variety of patterns and patterns, its decorative property is stronger than that of coated plate. Plastics can also contain a variety of additives in the production process, so that the laminate can obtain many finished product properties that ordinary coated sheet does not have, such as bending, stamping and folding. In addition, the plastic film is more compact, less water absorption and permeability, so it has strong corrosion resistance. As a new type of composite material, it has attracted more and more attention.
