Move the heat shrink sleeve to the centered position at the joint and take out the isolation material. Heat evenly from the center along the circumference, make it shrink completely and then extend the heating to both ends respectively. Pay attention to the even fire. After all the shrinkage is completed, reheat the uneven surface to make it completely flat. After the overall heating is completed, turn down the flame and reheat again to make the hot melt adhesive fully overflow. During the heating process, use the pressure roller to roll the joint several times, focusing on rolling the fusion lap to eliminate air bubbles.
Feature
1.Fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life, convenient transportation and fast construction.
2. 3Layer Fiber
reinforced PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back, a middle layer of fiber and special heat melt adhesive an. The 3 layer reinforced sleeve gives better shrink ratio, and better strength. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.
Application area:
It is mainly used for Hollow wall spiral pipe, corrugated pipe and metal reinforced corrugated spiral pipe etc.
TEST PROCEDURE
1. Clean the steel pipe and heat it by fire till over 80 ºC
2. Paint the steel pipe with Primer (mixed with A&B)
3. Fire heat the heat shrink sleeve, be attention to start heating from middle of the sleeve, but act from up and down, and gradually move from middle to two sides of sleeve, in order to drive air out of the sleeve, after finish heating, the good result is that there is about 1-2mm hot adhesive melt at the edge of sleeve.
TEST RESULT
1. Test result after cooling about 40 minutes.
Peel strength to primer is over 100N per 2cm(till the end of the spring balance). at 30.7ºC
Co-adhesive: Half-half.
2. Test result after cooling about 24hours.
Peel strength to primer is over 172N per 2cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
3. 2. Test result after cooling about 24hours.
Peel strength to primer is over 9.2kg/90N per 1cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
