Polyethylene anticorrosion adhesive tape from the polyethylene composition of the substrate and the corrosion of industrial-type tape. From the basement membrane and the layer composed of two parts, the base film is polyethylene membrane, for the butyl rubber layer, a very good mechanical strength and adhesive sealing performance. According to their role can be divided into anti-corrosion zone (inner zone), the protection zone (outer), mending tape. Level requirements under the coating is divided into general level, strengthening class and special strengthening class. 1, the total thickness of the coating level (mm) anti-corrosion layer General level ≥ 0.70 within a layer of primer + with + a layer of outer layer Strengthen the level ≥ 1.40 within a layer with a layer of primer + (lap as the tape width 50 ~ 55%) + outer layer (the width of the lap belt 50 to 55%) |
