The Use Of Copolymer Tape
May 12, 2017

1. Two or three layers of plastic appearance is usually uniform white plastic particles, with thermoplastic process performance, can be used general plastic molding equipment processing.

2. Two-layer adhesive for 2PE, 3PE anti-corrosion structure of the extrusion winding process and extrusion coating process. Powder can also be made for powder coating.

3. Two or three layers of plastic extrusion processing recommended process parameters:

Temperature: Feeding section 150 ℃ -170 ℃, head 190 ℃ -200 ℃, compression section 170 ℃ -180 ℃, adapter 200 ℃ -230 ℃, homogenization section 180 ℃ -200 ℃, die 190 ℃ -230 ℃

Extruder screw speed: should be based on the extruder screw structure, screw length to diameter ratio, die modulus, melt extension length (die and steel pipe distance), ancillary equipment, processing speed and other conditions set and adjust.

4. Two three-layer adhesive for 2PE anti-corrosion structure, the recommended heating temperature of steel pipe in the 200 ℃ -230 ℃ between the adjustment.

5. Two three-layer adhesive for 3PE anti-corrosion structure, the steel pipe heating temperature should be based on matching epoxy powder gelation time to determine. Recommended steel pipe heating temperature between 150 ℃ -200 ℃ adjustment.
