针对部分厂家钢带增强聚乙烯螺旋波纹管产品添加劣质回收塑料,以及其存在的增强钢带与聚乙烯粘接不牢易脱层等产品质量问题,本文介绍了钢带增强聚乙烯螺旋波纹管产品如何防止厂家添加劣质回收塑料、如何进一步提高产品质量的几种方法,即产品以浅色聚乙烯为内壁、采用镀锌钢带代替易生绣的普通钢带作为增强支撑体,封堵波纹内腔等,有效保证了管材的质量和使用寿命。 For some manufacturers to enhance polyethylene spiral corrugated pipe products add poor quality recycled plastics, and its presence to enhance the adhesion of steel and polyethylene is not easy to delamination and other product quality problems, this article describes the steel reinforced polyethylene spiral bellows How to prevent manufacturers from adding poor quality recycled plastics, how to further improve product quality, that is, products with light-colored polyethylene as the inner wall, the use of galvanized steel instead of easy to embroider the ordinary steel belt as a reinforcing support, sealing the corrugated Cavity, etc., effectively ensure the quality and service life of the pipe.
