Standard for use of aluminium plastic composite belt for optical cable
Jun 25, 2018

Under normal circumstances, in order to meet the requirements of the use, the main standards adopted in the production of aluminum and plastic composite belts for optical cables are YD/ t723-2007. So, do you know what is the main content of the aluminum plastic composite belt used in optical cables? The following is a brief introduction to the main requirements for the use of aluminum plastic composite for optical fiber.

First of all, in order to ensure the quality of aluminum-plastic composite belt use, as cable with lu: su composite products, the use of aluminium strip should belong to GB8544 industrial pure aluminum belt, USES the brand for L1, L2, L3, M. At the same time, we must ensure that the tolerance of thickness is maintained within or below 8%.

Secondly, if the polyethylene composite belt is used, the plastic layer of aluminum plastic composite belt should be made of low density polyethylene resin material which meets the requirements of GB11115. If it is a copolymer composite belt, the plastic layer needs to be made of ethylene-acrylic copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), etc.

Third, the application of the aluminum composite belt requires the whole surface to be flat and smooth, and it is very uniform, and it must not contain any defects such as impurities, folds, and spots. After the cut, the side of the composite belt should be flat, and the side should not be more than two millimeters. At the same time, it is necessary to ensure that the end face has no edge, gap, burr and other mechanical damage. In addition, when pulling out, the edges should have no obvious wavy shape.

In addition, the thickness and width of the aluminum composite belt should be determined according to the actual requirements. In addition, the tensile strength of the aluminum-plastic composite belt should not be less than 65MPa, the elongation is not less than 15%, the peel strength is not less than 6.13n /cm, and the thermal strength is not less than 17.5n /cm. http://www.copolymercoatedaluminumtape.com/
