日前,青岛华仕达机器有限公司自主研制的新型一步法塑料热收缩带生产线顺利通过了专家鉴定。在大量的防腐、化工、热力以及市政排污管网建设中,经常有因焊接不严造成渗漏,导致环境二次污染。因此,作为塑料管道的接口联接件,塑料热收缩带起着非常重要的作用,研究提高其焊接质量 Recently, Qingdao Hua Shida Machinery Co., Ltd. independently developed a new one-step plastic heat shrinkable belt production line passed the expert appraisal. In a large number of anti-corrosion, chemical, heat and municipal sewage pipe network construction, often due to lack of welding caused by leakage, resulting in secondary pollution of the environment. Therefore, as a plastic pipe interface connector, plastic heat shrinkable tape plays a very important role in the study to improve its welding quality
