中空玻璃密封材料是防止中空氣體逃逸的重要組成，“密封膠”顧名思義他主要是起密封作用的。中空玻璃的密封，中空玻璃GB/T11944-2002標(biāo)準(zhǔn)中的五項(xiàng)性能指標(biāo)。除紫外線照射是測試中空玻璃密封膠是否含有影響視線的揮發(fā)物外，另外四項(xiàng)指標(biāo)“密封性能、初始露點(diǎn)、高溫高濕、氣候循環(huán)”，都是檢測中空玻璃在各種環(huán)境下的密封性能的。 我們知道，一塊合格的中空玻璃產(chǎn)品不僅需要規(guī)范的操作工藝，更需要能滿足中空玻璃性能要求的密封材料，不同的中空玻璃密封膠，由于其性能的不同，所采用的生產(chǎn)工藝以及產(chǎn)品的綜合性能也不同。下面來看看中空玻璃密封膠的施工過程要注意些什么？
Insulating glass sealing material is an important component to prevent the escape of hollow gas. "Sealant" as the name suggests, it mainly plays a sealing role. The sealing of insulating glass includes five performance indexes in insulating glass GB / T11944-2002 standard. In addition to ultraviolet radiation, which is used to test whether the insulating glass sealant contains volatiles that affect the line of sight, the other four indicators "sealing performance, initial dew point, high temperature and humidity and climate cycle" are used to test the sealing performance of insulating glass in various environments. We know that a qualified insulating glass product needs not only standardized operation process, but also sealing materials that can meet the performance requirements of insulating glass. Different insulating glass sealants have different production processes and comprehensive properties of products due to their different properties. What should we pay attention to the construction process of hollow glass sealant?

密封膠的施工過程也有一些嚴(yán)謹(jǐn)?shù)牟襟E，包括玻璃切割和清洗、隔條切割和清潔、干燥劑的選擇和充填、上隔條、合片和打膠。有些必要的環(huán)節(jié)一定要注意下：
There are also some rigorous steps in the construction process of sealant, including glass cutting and cleaning, spacer cutting and cleaning, selection and filling of desiccant, upper spacer, lamination and gluing. Some necessary links must be noted as follows:
1、雙道密封膠一定要與玻璃、間隔條等兼容；二道膠應(yīng)保證雙組份混合質(zhì)量并做蝴蝶試驗(yàn)；
1. Double sealant must be compatible with glass, spacer, etc; The second layer of glue shall ensure the mixing quality of two components and conduct butterfly test;
2、一道密封需要做到連續(xù)均勻；
2. One seal shall be continuous and uniform;
3、二道密封也一定要做到連續(xù)均勻，中空玻璃生產(chǎn)的所有環(huán)節(jié)都會(huì)直接或間接影響中空玻璃密封膠的施工質(zhì)量。且與一道密封膠完全接觸；
3. The secondary sealing must also be continuous and uniform. All links of insulating glass production will directly or indirectly affect the construction quality of insulating glass sealant. And fully contact with a layer of sealant;
4、聚異丁烯膠與二道密封結(jié)構(gòu)膠的正確比例為135間隔框擺放一定要與玻璃邊緣等距離平行。有些密封膠還會(huì)摻油，由于摻油中空玻璃密封膠的熱失重大，經(jīng)過加速老化實(shí)驗(yàn)，摻油中空玻璃密封膠出現(xiàn)了表面龜裂現(xiàn)象，表明其耐久性能會(huì)有較大的降低，進(jìn)而對中空玻璃的使用壽命產(chǎn)生嚴(yán)重的影響。由此可見，密封膠的質(zhì)量決定著中空玻璃的真空性能。
4. The correct ratio of polyisobutylene glue to secondary sealing structural glue is 135. The spacing frame must be placed equidistantly parallel to the edge of the glass. Some sealants can also be mixed with oil. Due to the significant heat loss of oil mixed insulating glass sealant, the surface cracking of oil mixed insulating glass sealant appears after accelerated aging test, indicating that its durability will be greatly reduced, which will have a serious impact on the service life of insulating glass. It can be seen that the quality of sealant determines the vacuum performance of insulating glass.
