双扣聚乙烯增强管常见缺陷及形成原因

作者: laobingguandao    来源:http://www.laobingguandao.com  时间:2020-09-27    人气:
双扣聚乙烯增强管的使用规模越来越广,施工需求量增大,市场上许多质量低质的双扣聚乙烯增强管也混入其间,牟取暴利,不会人员底子无法分辩,对客户形成很大的丢失。为使客户选购时不被遮盖,以下双扣聚乙烯增强管为我们具体介绍PE双壁波纹管常见缺点的缘由剖析:
The use scale of double buckle polyethylene reinforced pipe is more and more widely, and the construction demand is increasing. Many low-quality double buckle polyethylene reinforced pipes in the market are also mixed in it to make huge profits, which will cause great loss to customers. In order to avoid being covered when customers choose and buy, the following double button polyethylene reinforced pipe specifically introduces the causes of common defects of PE double wall corrugated pipe:
Double button polyethylene reinforced pipe
内层有划痕:通常由于料温过高致使内层口模上粘有糊料;料内有杂质;水套上有划伤;内层口模有划伤等。
Scratch on the inner layer: paste sticking on the inner die due to high material temperature; impurities in the material; scratch on the water jacket; scratch on the inner die, etc.
外壁有小孔:其缘由是物料内有杂质;某区段温度失控致物料烧糊,糊料时而被带出;为了进步管材功用而参加的有些如功用母料、消泡剂等的分散性欠好,或许说与根底树脂的相容性欠好。
There are small holes in the outer wall: the reason is that there are impurities in the material; the temperature of a certain section is out of control, which causes the material to burn, and the paste is sometimes taken out; in order to improve the function of pipe materials, such as functional masterbatch, defoamer, etc., the dispersion is not good, or the compatibility with the root resin is not good.
管材的波峰歪斜由成型机速度过快冷却欠好、正常冲气气压过小导致。
The wave crest skewness of the tube is caused by the speed of the forming machine is too fast, the cooling is not good, and the normal air pressure is too small.
管材的重量不稳定一般是因为原材料的性能不稳定或下料段的温度波动过大。
The weight instability of pipe is generally due to the unstable performance of raw materials or excessive temperature fluctuation in the blanking section.
管材曲折缘由是外层的偏壁严峻或水套与成型机的对中性未调好。
The reason for the tortuosity of the pipe is that the outer wall is severe or the water jacket and the molding machine are not well aligned.
轴向上波峰的厚度不一致正常冲气过大、口模的空隙过大等导致。
The thickness of the axial wave crest is not consistent, the normal air blowing is too large, and the gap of the die is too large.

内壁不平整。内壁不平整一般由真空度偏小、水套温度过高、内层过薄等引起。真空度偏小应当检查内层真空管路是否畅通,真空泵是否工作正常等。水套温度过高一般是因为冷却水的水温过高或冷却水的流量过小引起,可通过这两个方面的调整来解决。
The inner wall is not smooth. The inner wall unevenness is generally caused by low vacuum degree, high temperature of water jacket and thin inner layer. If the vacuum degree is too small, check whether the inner vacuum pipeline is smooth and whether the vacuum pump works normally. The high temperature of the water jacket is usually caused by the high temperature of the cooling water or the low flow rate of the cooling water, which can be solved by adjusting the two aspects.
内层有划痕:一般因为料温过高致使内层口模上粘有糊料;料内有杂质;水套上有划伤;内层口模有划伤等。
Scratch on the inner layer: paste sticking on the inner die due to high material temperature; impurities in the material; scratch on the water jacket; scratch on the inner die, etc.
外壁有小空隙:因是物料内有杂质;某区段温度失控致物料烧糊,糊料时而被带出;为了提高管材性能而加入的部分如功能母料、消泡剂等的分散性不好,或者说与基础树脂(PE)的相容性不好。
There are small gaps in the outer wall: there are impurities in the material; the material is burnt due to the temperature out of control in a certain section, and the paste is taken out from time to time; the dispersion of the parts added to improve the performance of the pipe, such as the functional masterbatch and defoamer, is not good, or the compatibility with the base resin (PE) is not good.
