Effects of materials used in composite tapes and composite processes on process characteristics and quality of optical cables

Through the analysis of the present situation of steel-plastic composite tape and aluminum-plastic composite tape and the production technology of composite tape, the paper introduces the influence of composite tape material and production technology on the technology and quality of optical cable, and how to identify the advantages and disadvantages of the material, and the problems to be considered in the selection of composite tape.

Keywords: cable material, chrome-plated steel plastic composite belt, smooth type aluminum-plastic composite belt, chrome-plated steel tape, plastic film, double three-dimensional technology co., LTD., zhejiang www.zjsyal.com for global customers with perfect solutions of composite materials, copper products cover plastic composite strip/gangsu composite tape/lu: su composite tape, aluminum foil, PET belt, mica tape, aluminum plating film and so on, is applied to the cable, optical cable shielding layer, refrigeration, flexible duct and building heat insulation, and other fields.

Gangsu composite belt, aluminum-plastic composite belt is mainly used for communication cable, communication cable outer sheath, and sheath materials bonded together constitute a comprehensive protection layer, protect the core from moisture erosion of tidal level, the role of armoured cable to play at the same time, resistance to external forces, for the communication optical cable, communication cable, such as in a variety of applications to provide mechanical protection, guarantee the stability and reliability of the application.

Optical communication with optical fiber as carrier has the characteristics of extremely wide transmission frequency band and large communication capacity. In modern communication, optical fiber communication is widely used for ultra-large capacity signal transmission. Therefore, the reliability and stability of carrier are very high, otherwise it may lead to large communication barriers.In the long distance cable communication system, the transmission characteristics of fiber optic cable should be more stable for a long time.Make fiber optic cable, is to choose the performance of good raw materials, fiber protection, ensure the reliability of the use of fiber transmission, stability.In the fiber optic cable, steel - plastic composite belt, aluminum - plastic composite belt to protect the fiber has a very important role.

1. Mechanical properties:

The tensile strength, RP0.2(non-proportional elongation) and elongation at break are determined by the metal base band of the composite band and reflect the performance of the base band.

2. Bonding performance:

Peel strength - an indicator of bonding performance between a metal substrate and a thin film.According to the test results of the steel-plastic composite strip, four product samples were found to be unqualified, among which two product samples, surface A and surface B, were unqualified in terms of peel strength.Only A few manufacturers' products are very good. The peel strength of A and B are both very high with A small difference, and the standard deviation is only 0.114.The steel base strip it USES is imported chrome-plated steel strip.

3. Compatibility:

Metal plastic composite tape and optical cable paste long-term contact, so the need to consider the compatibility with ointment.The test of fill-resistant composite is to observe whether the foam or lamination will occur between the metal base band and the copolymer film in the ointment, that is, to examine the compatibility of the composite band and the filling ointment of optical cable.

4. Corrosion resistance

Check whether the metal plastic composite belt will be layered between the copolymer film and the metal base band in an acidic or alkaline environment, and whether it will cause corrosion to the metal base band.
