Inner and outer tapes of polypropylene anticorrosive tape
一分彩When the polypropylene anticorrosive tape is used to strengthen the anticorrosion, the inner tape (anticorrosive tape) and the outer tape (protective tape) should be used at the same time. The selection method is as follows:
一分彩1. The anticorrosive layer of polypropylene anticorrosive tape should be used with inner and outer tapes with a thickness of 0.4mm. According to the prescribed winding method, the design requirements for the total thickness of the anticorrosive layer greater than 1.4mm can be achieved. mm). That is to say, the thickness of the adhesive tape is only required to be close to a quarter of the total thickness of the anticorrosive layer required by the design.
Because the inner and outer tapes are each overlapped and wrapped at 50%, it is equivalent to the anticorrosive layer consisting of four layers of tape. If the design requires the anticorrosive grade to be enhanced, it is not specified that the inner and outer tapes are used to form the anticorrosive layer. For the minimum thickness of the reinforced anticorrosive layer with a total thickness of 1.4mm or smaller diameter steel tube corrosion protection, a thickness of 0.8mm can be selected, and the designed corrosion resistance can be achieved by overlapping at 50% once. The total thickness of the layer is required: 0.8mm x 2 = 1.6mm.
2, the anti-corrosion layer should use an inner band with a thickness of 0.5mm and an outer band with a thickness of 0.55mm. The inner band is wrapped with 50% overlap and the outer band is wrapped with 10% overlap. The total thickness of the anti-corrosion layer after anti-corrosion construction is: 0.5mmx2 + 0.55mm = 1.55mm.
一分彩3. The anti-corrosion layer of polypropylene anti-corrosion tape is suitable for inner tape with thickness of 0.5mm and outer tape with thickness of 0.4mm. The inner band is wrapped with 50% overlap and the outer band is wrapped with 10% overlap. The total thickness of the anti-corrosion layer after anti-corrosion construction is: 0.5mmx2 + 0.4mm = 1.4mm.
一分彩Polypropylene anticorrosive tape is not necessarily as thick as possible. To strengthen anticorrosion, it is necessary to use both inner and outer tapes. Anticorrosive tape manufacturer
