摘　　要：目的对目前PE薄片管材的主流热封方法进行归纳总结,为后续的研究提供依据。方法综述PE薄片作为软管热封的优缺点,分析PE薄片管材的热封和其他因素的影响,探讨目前比较先进的灌装封尾机构的现状。结果PE大多用于膏体的灌装上,其密封性能除了与材料有关外,也与其密封条件有很大关系,其密封方法一般采用热封方式。PE薄片管材热封后的性能与热封的三个要素(热封时间、温度和压力)有关,其中最重要的是热封温度。结论目前企业用得最多的热封方法是内加热,PE薄片管材采用水平封尾更加稳定。热封尾工艺要求达到一定的机械强度和足够的密封性。The work aims to summarize the several main heat sealing methods for PE thin sheet pipe to further provide the basis for the subsequent study.The advantages and disadvantages of PE thin sheets as hose heat sealing materials were summarized,the heating sealing of PE thin sheet pipe and effects of other factors were analyzed and the status of current advanced filling and sealing mechanism was discussed.PE was mostly used for paste filling,with sealing performance not only related to the material,but also in a great relationship with the sealing conditions.The sealing method was usually heat sealing.The performance of PE thin sheet pipe after heat sealing was related to the three heat sealing elements(heat sealing time,temperature and pressure)and the most important factor was heat sealing temperature.At present,the most popular heat sealing method adopted by enterprises is internal heating.PE thin sheet pipe is more stable when sealed horizontally.The heat sealing technology can realize certain mechanical strength and enough tightness.
