涂膠+PE環繞糾纏擠出機:膠粘劑環繞糾纏:因為聚乙烯層與熔結環氧涂層粘接力較差,操縱膠粘劑進步熔結環氧涂層與聚乙烯層兩種差別極性資料粘接力,膠粘劑的涂敷必須在環氧粉末膠化進程中停止。
Gluing + PE winding extruder: adhesive winding: due to the poor adhesion between polyethylene layer and fusion bonded epoxy coating, the adhesive is used to improve the adhesion between fusion bonded epoxy coating and polyethylene layer, and the application of adhesive must be carried out in the process of epoxy powder gluing.
