聚乙烯喷塑料生产工艺流程
English: The production process of polyethylene powder coating
involves several steps. First, the parts or products to be coated are
cleaned and prepared to create a clean and smooth surface. This can
be achieved through processes like washing, degreasing, or
sandblasting. Next, the cleaned components are preheated to
enhance the adhesion of the polyethylene powder. The preheating
temperature typically ranges from 120 to 200°C and can be adjusted
depending on the substrate and powder type. After preheating, the
parts are electrostatically charged using specialized equipment. The
polyethylene powder, which carries opposite charge, is then sprayed
onto the positively charged parts. The charged powder adheres to
the surface of the components due to electrostatic attraction. Once
the parts are evenly coated, they are transferred into a curing oven.
The curing oven is set at a specific temperature and duration to melt
and fuse the polyethylene powder onto the substrate. This process,
known as fusion bonding, creates a strong, durable, and protective
coating. After curing, the components are cooled down and
inspected for quality, ensuring that the coating thickness,
appearance, and adhesion meet the desired specifications. Any
defects or imperfections are corrected before the coated products
are packaged and prepared for shipment. This production process
allows for efficient and reliable application of polyethylene powder
coating, providing a range of benefits such as corrosion resistance,
impact protection, chemical resistance, and decorative finishes.
中文翻译: 聚乙烯喷塑料生产工艺流程包括几个步骤。首先，要涂覆的零部
件或产品经过清洁和准备工作，以获得干净和平滑的表面。这可以通过洗涤、
脱脂或喷砂等工艺实现。接下来，清洁的零部件被预热，以增强聚乙烯粉末
的附着力。预热温度通常在120至200°C之间，并可根据基材和粉末类型
进行调整。预热后，使用专用设备对零部件进行静电带电。然后将带有相反
电荷的聚乙烯粉末喷涂到带正电荷的零部件上。由于静电吸引力，带电的粉
末粘附在零部件的表面上。一旦零部件均匀涂覆，它们被转移至固化烤箱。
固化烤箱设定特定的温度和时间，使聚乙烯粉末熔化并与基材融合。这个称
为熔融结合的过程可以产生强度高、耐用和保护性的涂层。固化后，零部件
被冷却并进行质量检查，以确保涂层的厚度、外观和附着力符合所需的规格。
在涂覆产品包装和准备出货之前，会修复任何缺陷或瑕疵。这个生产工艺能
够高效可靠地应用聚乙烯喷塑料涂层，提供诸如抗腐蚀、防护、耐化学腐蚀
和装饰效果等一系列好处。
