摘要
管道防腐补口质量除了受施工影响外,很大程度上取决于热收缩带补口材料自身的质量,其直接决定了管道整体防腐的安全。结合当前收缩带补口材料国内外标准中有关测试参数及其指标的相关规定,制定并完善了收缩带补口材料的试验比对方案,对收集到的国内外主流生产厂商的8种收缩带材料,依据统一的规则进行编号,按照底漆的厚度、剪切强度、底漆固含量及吸水率、阴极剥离、粘结强度等多项指标对试验材料进行比对分析,并据此提出了对现行标准相关指标的修订建议。
The installation quality of field coating for welded joint with heat shrinkable tape depends to a great extent on the quality of coating material except the impact of installation way, which is directly related to the integral safety for the corrosion control of pipeline. Taking into account of the relevant regulations on testing parameters and criteria specified currently in the standards for joint coating materials of heat shrinkable tapes, a test comparison program of joint coating materials as heat shrinkable tapes has been formulated and perfected. Totally, eight types of heat shrinkable tape materials collected from the major manufactures in China and abroad have been code numbered according to the consistent rules, and compared and analyzed in terms of primer thickness, shear strength, solid content and water absorption of primer, cathodic disbonding and adhesion strength, and therefore, a suggestion for amendment of the relevant criteria in the existing standards has been proposed. （6 Tables, 13 References）
