了解自封袋的復合材料涂布工藝
發布于:2021/05/27 自封袋廠家的制作是涂層復合加工方法,聚合物封面材料在擠壓機中加熱融化后,通過機頭在基板表面涂層,形成復合材料。常用器材很多,包括紙、紙板、鋁箔包、玻璃紙、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.
自封袋的制作與擠出復合過程一樣,如果擠出器將單個材料擠出到單個流道模具中,則單個擠出涂層復合過程的結果涂層材料為單層。當擠出機同時向多道模具擠出多個材料時,通過同時擠出的復合過程,得到的覆蓋材料為多層,包括擠壓機、磁頭、冷卻輥、壓縮輥等組成的擠壓涂層復合裝置、輥部分、輥部分、修剪裝置和其他輔助裝置。

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.
聚合物涂料與自封袋基材之間以物理或化學方式結合的擠出涂層復合工藝,對于紙等多孔結構的基板,其結合是物理方式,聚合物油漆滲透到孔縫中,形成連續的涂層薄膜。玻璃紙、塑料薄膜、自封袋等光滑表面的基材,在復合前通常用粘合劑或紫外線照射等方法處理,提高復合膜的復合強度,涂布工藝技術的高低真的會影響產品的質量。
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.
