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?

剖析济南双组份打胶机更常见问题的处理方法--不粘

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

1、事前是否按标准做相容性测验

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

2、维护时间短就进行剥离性粘结测验，维护温度较低(尤其在冬天)

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

3、中空玻璃打胶机泵的气压缺乏，导致胶混合不匀，粘结作用要差些，同时容易形成枪头压力缺乏，打的胶缝不细密(密实度不行)

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、设备故障问题，导致胶混合作用欠安。假如打胶机的气缸密封垫磨损的时分，就会导致不一致的固化剂混合入胶内，AB泵工作行程不同步或者不匹配，AB组分混合不均匀，呈现花胶情况。有些在刚打完胶时还查看不出来，等胶干透了，就会透过玻璃看到花胶。可选用接连挤出测验来判断一下，即在一张平板上来回打出一条蛇形的密封胶，时间维持在三到五分钟，让泵少运转2个周期，查看是否存在异常情况(即所谓的软点)。

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、双组份打胶机不同厂家的AB胶混用

5. Mixing of AB glue from different manufacturers

6、溶剂不符合要求，或未干透等。特别需求留意的一点是胶在维护的阶段，胶的固化和胶的粘结性建立是独立的，就是说就是胶到达彻底固化，并不意味着胶和基材建立了彻底的粘结性。尤其对双组份来说特别显着。因而，玻璃单元接受应力前要答应有满足的时间来建立粘结性，这一点非常重要。

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.
