双组份打胶机注胶时容易出现哪些问题?

发布时间:2019/10/14    发布人:

  作为通常用于中空玻璃设备的产品,组件涂胶机有时会在购买低价或二手设备时遇到一些问题。 如何解决这些问题?
  As a product commonly used in insulating glass equipment, component glue coaters sometimes encounter some problems when purchasing low-cost or second-hand equipment. How to solve these problems?
  首先,从生产过程开始
  First, start with the production process
  在双程密封过程中,次密封使用丁基橡胶。 其主要功能是将铝带固定在适当的位置,以减少边缘处水蒸气和气体的渗透性。 中空玻璃的第二种密封剂是硅酮密封剂,聚硫化物密封剂,聚氨酯密封剂,亚结构组件和非结构组件。 第二种密封剂在中空玻璃中的功能如下:一种是密封气体,即将气体保持在空气层中,从而有利于中空玻璃的性能。 第二个是键合,即牢固地连接组件。 共同保持中空玻璃的结构稳定。
  In the process of two-way sealing, butyl rubber is used for the first time. Its main function is to fix the aluminium strip in an appropriate position to reduce the permeability of water vapor and gas at the edge. The second sealant for hollow glass is silicone sealant, polysulfide sealant, polyurethane sealant, sub-structural component and non-structural component. The function of the second kind of sealant in the hollow glass is as follows: one kind is the sealing gas, which keeps the gas in the air layer, thus advantageous to the performance of the hollow glass. The second is bonding, i.e. firmly connecting components. The structure of hollow glass is stable.
  第二种分析双组分涂胶机解决常见问题的方法-不粘
  The second method of analyzing two-component glue coating machine to solve the most common problems-non-stick
  1.是否根据规格预先进行了兼容性测试?
  1. Are compatibility tests conducted in advance according to specifications?
  2,固化时间短,进行剥离试验,固化温度低(尤其是冬天)
  2. Short curing time, peeling test, low curing temperature (especially in winter)

双组份打胶机
  3,中空玻璃胶机泵的气压不足,导致胶水混合不均匀,粘接效果更差,枪头压力不足,胶接点不致密(密度为 不够)
  3. Insufficient air pressure in the pump of hollow glass glue machine leads to uneven glue mixing, worse bonding effect, insufficient pressure of gun head and less compact bonding joint (density is insufficient).
  4,设备故障问题,导致胶水混合效果差。 如果涂胶机的气缸密封件磨损,则会导致不一致的固化剂混入胶水中。  AB泵的工作冲程不同步或不匹配,AB组分混合不均匀,橡胶处于故障状态。 胶水刚涂完时,其中一些无法检查。 胶水干燥后,可以透过玻璃看到胶水。 可以使用连续挤压测试来判断,即在平板上来回缠绕蛇纹密封胶三到五分钟,让泵至少运转2个周期,检查是否有异常情况(所谓的软点)。  )。
  4. Equipment malfunction leads to poor glue mixing effect. If the cylinder seals of the glue machine are worn, inconsistent curing agents will be mixed into the glue. The working stroke of AB pump is not synchronous or mismatched, the mixing of AB components is not uniform, and the rubber is in a failure state. When the glue was just finished, some of them could not be checked. When the glue is dried, the glue can be seen through the glass. Continuous extrusion test can be used to determine whether there are abnormal conditions (so-called soft spots) by winding the serpentine sealant back and forth on the plate for three to five minutes, allowing the pump to run for at least two cycles.
  5,二组分胶机,AB胶与不同厂家混合
  5. Two-component glue machine, AB glue mixed with different manufacturers
  6.溶剂不符合要求或没有变干。 特别重要的是要注意,在固化阶段,胶水的固化和胶水的粘合是独立的,也就是说,胶水已完全固化,并不意味着胶水和基材之间建立了完全的粘合。 对于两个组件尤其如此。 因此,重要的是要给玻璃单元足够的时间以使其在受压之前建立附着力。
  6. Solvents do not meet the requirements or have not dried. It is particularly important to note that during the curing stage, the curing of the glue and the bonding of the glue are independent, that is to say, the glue has been completely cured, which does not mean that there is a complete bonding between the glue and the base material. This is especially true for two components. Therefore, it is important to give the glass unit enough time to establish adhesion before it is compressed.
