雙組份打膠機中空玻璃設備常用的產(chǎn)品,在購買(mǎi)低或二手設備有時(shí)會(huì )有一些問(wèn)題,這些問(wèn)題是如何宏觀(guān)信息來(lái)源?
　　There are some problems in the purchase of low price or second-hand equipment for the products commonly used in the hollow glass equipment of two-component dispenser. How to solve these problems is the macro information source?
　　是生產(chǎn)過(guò)程
　　First, the production process
　　雙密封過(guò)程中，一道密封是丁基橡膠，其主要作用是將鋁帶固定在適當的位置，減少水蒸氣和氣體在邊緣的滲透。中空玻璃第二密封膠由硅酮密封膠、聚硫醚密封膠和聚氨酯密封膠組成，分為結構總成和非結構總成。第二種密封膠在中空玻璃中的作用是:一是起密封作用，即保持空氣層的氣體，使中空玻璃的性能得以保持;二是起到粘結作用，即各部件緊密連接在一起，保持中空玻璃的結構穩定性。
　　In the double seal process, the first seal is butyl rubber, which is mainly used to fix the aluminum strip in a proper position and reduce the penetration of water vapor and gas at the edge. The second sealant for hollow glass is composed of silicone sealant, polysulfide sealant and polyurethane sealant, which is divided into structural assembly and non structural assembly. The function of the second sealant in the insulating glass is: first, it plays a sealing role, that is, to keep the air layer gas, so that the performance of the insulating glass can be maintained; second, it plays a bonding role, that is, the components are closely connected to maintain the structural stability of the insulating glass.
　　第二部分分析了雙組份膠機更常見(jiàn)的問(wèn)題——不粘鍋
　　The second part analyzes the most common problem of two-component glue machine: non stick pot
　　1. 是否按照規范要求提前進(jìn)行兼容性測試
　　1. Whether the compatibility test is conducted in advance according to the specification requirements
　　2. 在養護時(shí)間短、養護溫度低(尤其是冬季)時(shí)進(jìn)行剝離粘結試驗。

　　2. Peel and bond test shall be carried out when the curing time is short and the curing temperature is low (especially in winter).
　　3、中空玻璃膠泵壓力不夠，導致膠液混合不均勻，粘接效果差，且容易造成封頭壓力不足，膠接頭不密(密度不夠)
　　3. The pressure of the insulating glass glue pump is not enough, which leads to uneven mixing of glue liquid and poor bonding effect, and it is easy to cause insufficient pressure of the head and poor density of glue joint
　　4. 設備故障導致攪拌效果不佳。如果橡膠機的氣缸墊片磨損，就會(huì )導致固化劑混入橡膠中不一致，AB泵工作行程不同步或不匹配，AB組分混合不均勻，花膠。有些剛涂完的膠不出檢查，如膠水干了，就會(huì )看不透玻璃花膠。連續擠壓試驗可用于確定在平板上前后生產(chǎn)三五分鐘的蛇紋石密封膠，使泵運行少兩個(gè)周期以檢查異常情況(所謂的軟點(diǎn))。
　　4. Equipment failure leads to poor mixing effect. If the cylinder gasket of the rubber machine is worn, it will lead to inconsistent mixing of curing agent into the rubber, asynchronous or mismatched working stroke of AB pump, uneven mixing of AB components and glue. Some of the glue just applied can't be inspected. If the glue is dry, it will not be able to see through the cellophane. The continuous extrusion test can be used to determine the production of serpentine sealant for three to five minutes before and after the plate, allowing the pump to run for at least two cycles to check for abnormal conditions (so-called soft spots).
　　5. 在雙組份制膠機上混合不同廠(chǎng)家的AB膠
　　5. Mix the AB glue of different manufacturers on the two-component glue making machine
　　6、溶劑不符合要求，或不干燥等。需要特別注意的一點(diǎn)是膠黏劑在固化階段，膠黏劑的固化與膠黏劑的粘結是獨立的，也就是說(shuō)，膠黏劑要完全固化，并不意味著(zhù)膠黏劑與基材要建立完全的粘結。對于雙組分尤其如此。因此，重要的是要讓玻璃單元有足夠的時(shí)間來(lái)建立粘結，然后再施加應力。
　　6. The solvent does not meet the requirements, or does not dry, etc. Special attention should be paid to the fact that in the curing stage, the curing of the adhesive is independent of the bonding of the adhesive, that is to say, the complete curing of the adhesive does not mean the complete bonding between the adhesive and the substrate. This is especially true for two components. Therefore, it is important to allow sufficient time for the glass element to establish the bond before applying the stress.
