雙組份打膠機作為中空玻璃設備中常常運用的產品，在購買低或者二手的設備有時會呈現一些問題，針對這些問題該是如何處理的呢?

As a product often used in insulating glass equipment, two-component gluing machine sometimes presents some problems when purchasing low-cost or second-hand equipment. How to deal with these problems?

從制作工藝入手

Starting from the production process

雙道密封工藝，道密封選用的是丁基膠，其主要作用是將鋁條固定在適宜方位上，降低水汽及氣體在邊際的滲透性。中空玻璃的第二道密封膠有硅酮密封膠、聚硫密封膠、聚氨酯密封膠幾種，分結構性安裝和非結構性安裝。第二道密封膠在中空玻璃中的作用是：一是起密封作用，即堅持空氣層內的氣體，然后有利于中空玻璃的性能堅持;二是起粘結作用，即把各元件結實的銜接在一起，堅持中空玻璃的結構穩(wěn)定。

In the double seal process, butyl rubber is selected as the first seal, which is mainly used to fix the aluminum strip at the appropriate position and reduce the permeability of water vapor and gas at the edge. The second sealant for insulating glass includes silicone sealant, polysulfide sealant and polyurethane sealant, which are divided into structural installation and non structural installation. The function of the second sealant in insulating glass is: first, it plays a sealing role, that is, it adheres to the gas in the air layer, and then is conducive to the performance of the insulating glass; the second is to play a bonding role, that is to firmly connect the components together, and adhere to the structural stability of the insulating glass.

剖析雙組份打膠機常見問題的處理方法--不粘

Analysis of the common problems of two-component gluing machine -- non sticking

1、事前是否按標準做相容性測驗

1. Is the compatibility test conducted according to the standard in advance

2、維護時間短就進行剝離性粘結測驗，維護溫度較低(尤其在冬天)

2. Peel bond test for short maintenance time, low maintenance temperature (especially in winter)

3、中空玻璃打膠機泵的氣壓缺乏，導致膠混合不勻，粘結作用要差些，同時容易形成槍頭壓力缺乏，打的膠縫不細密(密實度不行)

3. Due to the lack of air pressure in the pump of the insulating glass gluing machine, the glue mixing is uneven, and the bonding effect is poor. At the same time, it is easy to form a lack of gun head pressure, and the glue seam is not fine (the density is not good)

4、設備故障問題，導致膠混合作用欠安。假如打膠機的氣缸密封墊磨損的時分，就會導致不一致的固化劑混合入膠內，AB泵工作行程不同步或者不匹配，AB組分混合不均勻，呈現花膠情況。有些在剛打完膠時還查看不出來，等膠干透了，就會透過玻璃看到花膠。可選用接連擠出測驗來判斷一下，即在一張平板上來回打出一條蛇形的密封膠，時間維持在三到五分鐘，讓泵少運轉2個周期，查看是否存在異常情況(即所謂的軟點)。

4. Equipment failure, resulting in the rubber mixing function is not safe. If the cylinder gasket of the glue machine is worn, it will lead to inconsistent curing agent mixed into the glue, the working stroke of AB pump is not synchronous or mismatched, and ab components are not mixed evenly, showing the situation of flower glue. Some of them can't be seen when the glue is just finished. When the glue is dry, you will see the flower glue through the glass. Continuous extrusion test can be selected to judge, that is, a snake shaped sealant is punched back and forth on a flat plate for three to five minutes, and the pump is allowed to run for at least two cycles to check whether there are abnormal conditions (i.e., the so-called soft spot).

5、雙組份打膠機不同廠家的AB膠混用

5. Mixing of AB glue from different manufacturers

6、溶劑不符合要求，或未干透等。特別需求留意的一點是膠在維護的階段，膠的固化和膠的粘結性建立是獨立的，就是說就是膠到達徹底固化，并不意味著膠和基材建立了徹底的粘結性。尤其對雙組份來說特別顯著。因而，玻璃單元接受應力前要答應有滿足的時間來建立粘結性，這一點非常重要。

6. The solvent does not meet the requirements or is not dry. Special attention should be paid to the fact that during the maintenance stage, the curing of the adhesive and the establishment of the adhesion of the adhesive are independent, that is to say, the complete curing of the adhesive does not mean that the adhesive and the substrate have established a thorough adhesion. Especially for two components. Therefore, it is very important to allow a sufficient time to establish the adhesion of the glass unit before accepting the stress.
