乌克兰科学院推出一种利用光化学交联上述标题的新技术,用于石油或天然气等管道干线的防腐蚀。与传统的沥清涂复相比,克服了劳动条件、防腐效果差及施工不便等缺点。此技术是采用紫外光交联可热收缩的聚乙烯和热熔胶复合物,制成一定宽度的带子。这种带子缠包在管道外表面,经过加热后,热熔胶粘结层熔融,在管道外表面不平整部分可均匀填充,而热收缩聚乙烯经收缩
The Ukrainian Academy of Sciences has introduced a new technology that uses photochemical crosslinking of the above headings for the corrosion protection of pipelines such as oil or natural gas. Compared with the traditional bitumen coating, it overcomes the shortcomings of working conditions, poor anticorrosive effect and inconvenient construction. This technology is the use of UV cross-linked heat-shrinkable polyethylene and hot melt adhesive compound, made of a certain width of the tape. This tape wrapped around the outer surface of the pipe, after heating, the hot melt adhesive layer melts in the uneven part of the outer surface of the pipe can be uniformly filled, and shrinkage of shrinkage of polyethylene
