Appearance inspection and winding requirements of a steel plastic composite belt
May 15, 2018

In the process of inspection, the surface of the steel plastic composite belt should be smooth, smooth, free of impurities, no flowers, no creases and other mechanical defects. The side side of the steel plastic composite belt will be protected with 2mm to 5mm plastic film.

The side edge of the steel plastic composite belt should be smooth and without the defects such as curling, burr and notches in the process of use. The dislocation of the product should not be more than 5 mm. The side of the steel plastic composite belt should be flat and the side unevenness is less than 1mm.

In the process of use, the steel plastic composite belt should be tightly wound in the steel belt or aluminum or equivalent material into the core. The inner diameter of the product is 100mm + 2mm, 204 + 2mm, 406mm + 3mm and so on. The length of the pipe core of the steel plastic composite belt should be the same as the width of the steel plastic composite belt.

The pipe core of the steel plastic composite belt should be convex with the end face less than 1 millimeters. If the length of the pipe core without the segmentation product should exceed the side 5-10mm of the composite belt, the steel plastic composite belt should be used vertically in the process of use, and the belt should not be broken down.

The steel plastic composite belt is absolutely not allowed two or more products on the same core tube. The steel plastic composite belt of the same plate is absolutely not allowed to have two joints, but in the process of use, there will be a joint for the welding head and the length is less than 1.4km.

The thickness of the steel plastic composite belt joint is allowed to exceed 1.5 times of the original thickness in the process of use. The plastic layer at the joint should be restored in time. The joint should be marked, the distance between the two joints is not less than 305m, and the tensile strength of the joint should not be less than 85% of the adjacent non joint.http://www.copolymercoatedaluminumtape.com/
