Cable is in the 0.15-0.20mm thick aluminum foil attached to the upper and lower surface of a special plastic film (0.058mm thick) made. There are two kinds of sticking method and wet sticking method, dry method is to use the high temperature (200 ℃) rolling the film affixed to the way; wet method is glued adhesive. At present, most adopt dry method. After affixed with plastic film with a special instrument to tear the film from the foil to determine the degree of plastic film bonding firm, the determination of the data is very important, known as the peel strength. According to the communication cable industry standard (code YD / T 723.2-94) the strength should not be less than 6.13N / cm; In addition, the heat sealing strength should not be less than 17.5N / cm. Aluminum foil surface quality is the most important factor affecting the peel strength, the main surface quality problems are oil spots, corrosion, peroxide and so on.http://www.hongchengtm.net/
