The thickness of the aluminium foil layer is 7-12um.
EMAA layers of the thickness is 23-26um.
The thickness of the pet layer is 12um, and the thickness of the aluminium foil layer is 9um, and EMAA layers of the thickness is 25um.
The communication cable production method of environmentally friendly conductive copper aluminum foil shielded material, carries out according to the following steps：
1) distinguish clad aluminum layers of foil in the tow sides of the first pet layer, processing is then dried；
2) compound second pet layer on the semi-finished product that step 1) obtains, is then dried processing again；
3) then the complex copper layers of foil on the second pet layer that step 2) obtains carries out being dried again；
4) semi-finished product obtained in step 3) upper EMAA layers compound, the EMAA layers of outer surface for being compounded in copper foil layer, so
Last time drying process is carried out afterwards, that is, is completed；
Above the compound of each step is carried out by compounding machine；Compound tense is all made of flame-retardant glue.
Drying process in the step 1), to be spontaneously dried 5-7 days under indoor environment；Or in 60-75 DEG C of baking oven
Processing 36-72 hours.
Drying process in the step 2), to be handled 36-72 hours in 60-75 DEG C of baking oven.
