双扣聚乙烯增强管常见缺陷及形成原因!

  双卡扣聚乙烯增强管的使用规模越来越广泛,施工需求越来越大,市场上很多质量较差的双卡扣聚乙烯增强管也混在其中,牟取暴利,将无法区分背景,给客户造成很大损失。为了让客户买到不覆膜,下面为我们来介绍一下聚乙烯双扣增强管双壁波纹管常见的缺点分析:
  The use of double buckle polyethylene reinforced pipe is more and more extensive, and the construction demand is more and more large. Many poor quality double buckle polyethylene reinforced pipes are also mixed in the market, making huge profits, will not be able to distinguish the professional background, causing great losses to customers. In order to let customers buy non coated film, the following is an introduction to the common disadvantages of Polyethylene double button reinforced pipe double wall corrugated pipe:
  内层有划痕:通常由于材料温度过高,内层模具上有糊;物料中的杂质;水套上有划痕;内模有划痕。
  Scratch on the inner layer: usually due to the high temperature of the material, there is paste on the inner mold; impurities in the material; scratch on the water jacket; scratch on the inner mold.
  外墙开孔:原因是材料中有杂质;一个区域的温度失控,材料被烧毁。为了改善管道的功能和参与一些如母材的功能,消泡剂分散度不如好,也许说与根树脂的相容性不如好。
  External wall opening: the reason is that there are impurities in the material; the temperature of an area is out of control, and the material is burned. In order to improve the function of pipeline and participate in some functions such as base metal, the dispersity of defoamer is not good, maybe the compatibility with root resin is not good.
  由于成型机的快速冷却,管道的波峰歪斜,正常压力太小。
  Due to the rapid cooling of the molding machine, the wave crest of the pipeline is skewed, and the normal pressure is too small.

  管子重量不稳定一般是由于原料性能不稳定或下料段温度波动过大造成的。
  The instability of pipe weight is generally caused by the instability of raw material performance or excessive temperature fluctuation in the blanking section.
  管子弯曲的原因是严重的外壁或水套和造型机上的中性没有调整。
  The cause of the tube bending is the severe outer wall or water jacket and the molding machine on the neutral has not been adjusted.
  轴向波峰的厚度不一致。
  The thickness of the axial wave crest is inconsistent.
  内壁凹凸不平。内壁不平整一般是由真空度小、水套温度过高和内层过薄引起的。真空度太小时,检查内真空管是否畅通,真空泵是否工作正常。水套温度过高通常是由冷却水温度过高或冷却水流量过低引起的。
  The inner wall is uneven. The inner wall unevenness is generally caused by low vacuum, high water jacket temperature and thin inner layer. If the vacuum is too small, check whether the inner vacuum pipe is unblocked and whether the vacuum pump works normally. High jacket temperature is usually caused by high cooling water temperature or low cooling water flow.
  内层有划痕:由于材料温度过高,一般内层模具上有糊;物料中的杂质;水套上有划痕;内模有划痕。
  Scratch on the inner layer: due to the high temperature of the material, there is paste on the inner mold; impurities in the material; scratch on the water jacket; scratch on the inner mold.
  外墙缝隙小:因为材料中有杂质;一个区域的温度失控,材料被烧毁。为了提高管材的性能和添加功能母材等部件,消泡剂的分散性不佳,或与基树脂(PE)的相容性不佳。
  Small gap in the outer wall: because there are impurities in the material; the temperature of an area is out of control, and the material is burned. In order to improve the properties of pipes and add functional base metal, the dispersibility of defoamer is not good, or the compatibility with base resin (PE) is not good.
