了解自封袋的复合材料涂布工艺
发布于:2021/05/27 自封袋厂家的制作是涂层复合加工方法,聚合物封面材料在挤压机中加热融化后,通过机头在基板表面涂层,形成复合材料。常用器材很多,包括纸、纸板、铝箔包、玻璃纸、聚酯、拉伸聚丙烯、高密度聚乙烯等。
The production of self sealing bag manufacturers is a coating composite processing method. After the polymer cover material is heated and melted in the extruder, it is coated on the surface of the substrate through the die to form a composite material. There are many commonly used equipment, including paper, paperboard, aluminum foil package, cellophane, polyester, polypropylene, high density polyethylene, etc.
自封袋的制作与挤出复合过程一样,如果挤出器将单个材料挤出到单个流道模具中,则单个挤出涂层复合过程的结果涂层材料为单层。当挤出机同时向多道模具挤出多个材料时,通过同时挤出的复合过程,得到的覆盖材料为多层,包括挤压机、磁头、冷却辊、压缩辊等组成的挤压涂层复合装置、辊部分、辊部分、修剪装置和其他辅助装置。

If the extruder extrudes a single material into a single channel die, the coating material is a single layer. When the extruder extrudes multiple materials to multi-channel die at the same time, the covering material obtained by the simultaneous extrusion process is multi-layer, including extrusion coating composite device, roll part, roll part, trimming device and other auxiliary devices composed of extruder, magnetic head, cooling roll, compression roll, etc.
聚合物涂料与自封袋基材之间以物理或化学方式结合的挤出涂层复合工艺,对于纸等多孔结构的基板,其结合是物理方式,聚合物油漆渗透到孔缝中,形成连续的涂层薄膜。玻璃纸、塑料薄膜、自封袋等光滑表面的基材,在复合前通常用粘合剂或紫外线照射等方法处理,提高复合膜的复合强度,涂布工艺技术的高低真的会影响产品的质量。
Polymer coating and self sealing bag substrate are combined in physical or chemical way. For the porous structure substrate such as paper, the combination is physical way. Polymer paint penetrates into the pores to form a continuous coating film. The smooth surface substrates such as cellophane, plastic film and self sealing bag are usually treated with adhesive or ultraviolet radiation before compounding to improve the compounding strength of the composite film. The level of coating technology will really affect the quality of the product.
