PE双壁波纹管扩口不良的原因分析!

作者: admin    来源:http://www.laobingguandao.com  时间:2019-07-26    人气:
  PE波纹管作为一种排水管,在城镇、房屋、工厂及各种公共建筑中不断排除各种污水,它是利用机械原理设计的外墙波纹结构,科学合理,具有良好的物理力学性能。
  PE corrugated pipe, as a drainage pipe, continuously removes all kinds of sewage in cities, houses, factories and various public buildings. It is an external wall corrugated structure designed by mechanical principle, which is scientific and reasonable, and has good physical and mechanical properties.
  PE双壁波纹管在实际生产过程中,会遇到扩口不良的问题,下面我们具体分析一下。
  PE double-wall bellows in the actual production process, will encounter the problem of poor enlargement, below we specifically analyze.
  (1)内层吹破原因一般有内气压力过大;原材料韧性不佳;内层太薄;扩口放气启动较晚或扩口放气管道路径不畅通;原料中含有杂质;材料塑化不良等。
  (1) Internal blow-out causes are generally excessive internal pressure; poor toughness of raw materials; too thin inner layer; late start-up of expansion bleeding or blocked path of expansion bleeding; impurities in raw materials; poor plasticization of materials, etc.
  (2)如果扩口内层和外层没有正确附着,如果这种现象在开始时发生,则是由于内层启动较晚或相应截面的压力太小;如果发生在端部,可能是由于内层曝气的过早端或扩口放气的过早端,或由于相应截面的压力过低;如果从头到尾粘贴不好,可能是原材料的性能或温度问题。
  (2) If the inner and outer layers of the enlargement do not adhere properly, if this phenomenon occurs at the beginning, it is due to the late start of the inner layer or the low pressure of the corresponding section; if it occurs at the end, it may be due to the premature aeration of the inner layer or the premature exhaust of the enlargement, or the low pressure of the corresponding section; if it occurs from the beginning to the end, it may be due to the low pressure of the corresponding section. Poor pasting may be the performance or temperature of raw materials.
  (3)无论如何调整端面的扩口不完全,扩口不能贴附,其原因一般是内层的冲击过早结束;扩口放气提前结束;
  (3) No matter how to adjust the end face of the expansion is not complete, the expansion can not be attached, the reason is generally the premature end of the impact of the inner layer; the premature end of the expansion deflation;
  (4)扩口前部内层有凹极限,造成这种现象的原因是内层往往启动过早;水套与模块中心线偏差(成型机与水套不对齐);内壁厚度薄;内部真空过早停止。

  (4) There is concave limit in the inner layer of the front part of the enlargement, which is caused by the early start of the inner layer, the deviation between the water jacket and the center line of the module (the forming machine and the water jacket are not aligned), the thin inner wall thickness, and the premature stop of the internal vacuum.
  (5)在扩口端堆料的内层,这种现象往往导致扩口凹向内。其原因是扩口端内层过厚。本节注塑机的压下率过大;前几节的内层膨胀过度;内层材料温度过高,使毛坯过软;这部分外毛坯太厚了。
  (5) In the inner layer of the stack at the flaring end, this phenomenon often results in the flaring concave inward. The reason is that the inner layer of the expanding end is too thick. In this section, the reduction rate of the injection moulding machine is too high; the inner expansion of the previous sections is too high; the inner material temperature is too high to make the blank too soft; the outer blank of this section is too thick.
  6. 扩口端内层有凹极限,其原因一般是扩口后波和第二波压力过小;波和第二波的内壁厚度过厚。内真空度小或内真空度启动太晚;原材料韧性差等。
  6. There is a concave limit in the inner layer of the flare end. The reason is that the pressure of the first wave and the second wave is too small after flaring, and the thickness of the inner wall of the first wave and the second wave is too thick. The internal vacuum is small or the internal vacuum is too late to start; the toughness of raw materials is poor, etc.
