As glass manufacturers know, the quality of insulating glass is closely related to its production equipment. The sealing and structural stability of high quality insulating glass system are realized by insulating glass glue. Insulating glass is always faced with the influence of external water vapor penetration and temperature change during its service life. Therefore, insulating glass adhesive must be able to prevent external water vapor from entering the air layer of insulating glass.

中空玻璃安装之后由于经常面临来自外界的温差、气压、风荷载等外力的影响，因此要求中空玻璃胶还要保证系统的结构稳定。显然，保证中空玻璃空气层的密封和保持中空玻璃系统的结构稳定性是同样重要的。中空玻璃的密封性依赖于结构的完整性，而结构性保证密封性的稳定。

After the installation of insulating glass, due to the influence of external forces such as temperature difference, air pressure and wind load, the insulating glass glue is required to ensure the structural stability of the system. Obviously, it is equally important to ensure the sealing of insulating glass air layer and keep the structural stability of insulating glass system. The sealing performance of insulating glass depends on the integrity of the structure, and the structure ensures the stability of the sealing performance.

中空玻璃密封常用胶水有：硅酮胶、玻璃胶、硅胶等，常规的灌胶机都是把胶水倒进两个料缸，再通过定量泵配比、混合、定量供胶到产品，而由于中空玻璃所用胶水粘度都非常高要把这些胶水倒入料缸非常困难，所以中空玻璃打胶机区别于常规灌胶机的是：中空玻璃打胶机都是根据客户所用胶桶规格，量身订制压盘，打胶时通过压盘压胶，压盘上配有活塞泵或齿轮泵抽胶，客户只需把胶桶放到压盘机定位块上即可。

The common glue used in insulating glass sealing are silicone glue, glass glue, silica gel, etc. the conventional glue pouring machine always pour the glue into two material cylinders, and then mix and supply the glue to the product through the quantitative pump. Because the viscosity of the glue used in insulating glass is very high, it is very difficult to pour these glue into the material cylinder, Therefore, the insulating glass gluing machine is different from the conventional gluing machine: the insulating glass gluing machine is customized pressure plate according to the specifications of the gluing barrel used by customers. When gluing, the gluing is pressed through the pressure plate. The pressure plate is equipped with a piston pump or a gear pump to pump the gluing. Customers only need to put the gluing barrel on the positioning block of the pressure plate machine.

中空玻璃打胶机根据胶水可分为：单组份打胶机及双组份打胶机。

According to the glue, insulating glass gluing machine can be divided into single component gluing machine and two-component gluing machine.

单组份打胶机比较简单，只需一个压盘把胶水抽出定量打到产品即可。

Single component gluing machine is relatively simple, just need a pressure plate to draw out the glue to the product.

双组份打胶机：原理跟双液点胶机一样，根据客户AB胶桶量身订制两个压盘，把胶桶放入压盘下，通过压盘压胶再通过定量泵配比、混合、定量打到产品上。目前市面的中空玻璃打胶机大多数为活塞式打胶。

Two component dispenser: the principle is the same as that of the two-component dispenser. Two pressure plates are customized according to the customer's AB rubber barrel. Put the rubber barrel under the pressure plate, press the rubber through the pressure plate, and then mix, mix and quantitatively pump the rubber to the product. At present, most of the insulating glass gluing machines on the market are piston type gluing machines.

由于活塞式有一个抽胶的过程，经常会导致打胶的线条忽大忽小，所以广美玻璃机械的全自动中空玻璃打胶机采用可连续性供胶的二次加压技术，这样可保证打胶线条均匀，不会有忽大忽小的情况出现。

Because there is a process of pumping glue in the piston type, which often causes the lines of glue to change from big to small. Therefore, the fully automatic insulating glass glue machine of Guangmei glass machinery adopts the secondary pressure technology of continuous glue supply, which can ensure that the lines of glue are uniform and will not change from big to small.
