Polyethylene tape belt and to go inside and protect bring a difference

< br />

polyethylene tape in belt, used as a main antiseptic effect. Polyethylene protective belt mainly used for to go, protection. Polyethylene for belt, it is mainly used for weld repairing. Three besides has certain difference on purpose, they directly what different?

< br />

in the industrial standard SY/T0414 - before 98, PE protection tape, PE repairing belt with polyethylene anticorrosion performance is different thickness, basic no other performance difference, so the latest SY/T0414 - 2007 standard listed no longer protect the adhesive tape and repairing with performance requirements, rules to protect the performance of the adhesive belt, joint belt should meet the requirements of anticorrosion adhesive tape, but protect the adhesive tape peel strength of primer on steel, the thickness of the adhesive tape according to the selected anticorrosive layer structure, choose the corresponding product specifications. Acceptance test should be according to the specifications of the manufacturer that the data.

< br />

about polyethylene tape latest anticorrosive standards related to the change of the three, mainly as follows:

< br />

1) Be no prescribed scope of the thickness of the tape. Due to the adhesive tape products specification, species diversity, suitable anticorrosive layer structure is different, its thickness difference is bigger, so the provisions of this standard is no longer the thickness of the adhesive tape products. Design should be according to the requirements, determine the anticorrosive layer structure, and then selected adhesive tape products. When the acceptance inspection, mainly supply product production quality is stable, so the test specification e. deviation requirements for manufacturers.

< br />

2) Made an adjustment to the requirement of peel strength, improve the adhesive tape of primer for steel peel strength requirements; According to the characteristics of products and packaging form of adhesive tape, tape provides different products of peel strength value of the back piece.

< br />

3) Increase the performance of anticorrosive coating system requirements. Consult DIN30672 and EN12068 requirements, increased the impact resistance, anti-corrosion layer, using temperature of peel strength, such as cathodic disbonding performance requirements. These performance requirements using laboratory preparation of anti-corrosion layer section for testing, structure level, according to the requirements of design and engineering can also be tested according to the manufacturer recommendations.
