  作為通常用于中空玻璃設備的產品,組件涂膠機有時會在購買低價或二手設備時遇到一些問題。 如何解決這些問題?
  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,從生產過程開始
  First, start with the production process
  在雙程密封過程中,次密封使用丁基橡膠。 其主要功能是將鋁帶固定在適當的位置,以減少邊緣處水蒸氣和氣體的滲透性。 中空玻璃的第二種密封劑是硅酮密封劑,聚硫化物密封劑,聚氨酯密封劑,亞結構組件和非結構組件。 第二種密封劑在中空玻璃中的功能如下:一種是密封氣體,即將氣體保持在空氣層中,從而有利于中空玻璃的性能。 第二個是鍵合,即牢固地連接組件。 共同保持中空玻璃的結構穩定。
  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.

  1.是否根據規格預先進行了兼容性測試?
  1. Are compatibility tests conducted in advance according to specifications?
  2,固化時間短,進行剝離試驗,固化溫度低(尤其是冬天)

  3,中空玻璃膠機泵的氣壓不足,導致膠水混合不均勻,粘接效果更差,槍頭壓力不足,膠接點不致密(密度為 不夠)
  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,設備故障問題,導致膠水混合效果差。 如果涂膠機的氣缸密封件磨損,則會導致不一致的固化劑混入膠水中。  AB泵的工作沖程不同步或不匹配,AB組分混合不均勻,橡膠處于故障狀態。 膠水剛涂完時,其中一些無法檢查。 膠水干燥后,可以透過玻璃看到膠水。 可以使用連續擠壓測試來判斷,即在平板上來回纏繞蛇紋密封膠三到五分鐘,讓泵至少運轉2個周期,檢查是否有異常情況(所謂的軟點)。  )。
  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.
  5,二組分膠機,AB膠與不同廠家混合
  5. Two-component glue machine, AB glue mixed with different manufacturers
  6.溶劑不符合要求或沒有變干。 特別重要的是要注意,在固化階段,膠水的固化和膠水的粘合是獨立的,也就是說,膠水已完全固化,并不意味著膠水和基材之間建立了完全的粘合。 對于兩個組件尤其如此。 因此,重要的是要給玻璃單元足夠的時間以使其在受壓之前建立附著力。

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.
