中空玻璃結(jié)露會(huì)讓產(chǎn)品的品質(zhì)降低，影響正常的保溫隔音效果，下面全自動(dòng)封膠機(jī)廠家就給大家分析一下促使中空玻璃露點(diǎn)的升高的三種情況，希望對(duì)大家有所幫助！
Hollow glass condensation will reduce the quality of products, affecting the normal insulation and sound insulation effect, the following full-automatic sealant manufacturers will give you an analysis of the three conditions to promote the dew point of hollow glass, hoping to help you!
1.密封膠擠壓得太松或是里面有機(jī)械異物
1. Sealant is extruded too loosely or there are mechanical foreign bodies in it.
用兩道彈性密封膠把中空玻璃與鋁管間隔體結(jié)合在一起，一層使用丁基橡膠封存，第二層使用結(jié)構(gòu)硅酮膠密封。在現(xiàn)實(shí)操作過(guò)程中密封膠里如果存在機(jī)械異物或是在涂膠時(shí)擠壓得太松，導(dǎo)致膠體里面形成毛細(xì)管，并由于中間層里面和外面有壓差或濕度差，大氣里的水分進(jìn)入中空玻璃中間層，導(dǎo)致中空玻璃中間層里的含水量升高。
Two elastic sealants are used to combine hollow glass with aluminium tube spacer. One layer is sealed with butyl rubber and the second layer is sealed with structured silicone rubber. In the actual operation process, if there are mechanical foreign bodies in the sealant or when the sealant is extruded too loosely, the capillary is formed in the gel, and there is pressure difference or humidity difference between the inside and outside of the middle layer, the moisture in the atmosphere enters the middle layer of the hollow glass, which leads to the increase of water content in the middle layer of the hollow glass.
2.水汽透過(guò)密封膠進(jìn)到中間空氣層里
2. Water vapor enters the middle air layer through sealant
一般使用均勻高分子聚合物作為密封膠，但聚合物也并非完全不透氣，它兩側(cè)的逸度差(壓差或濃度差促進(jìn)了聚合物進(jìn)行等溫?cái)U(kuò)散。中空玻璃的密封膠的主要擴(kuò)散物是大氣里的水分，聚合物的氣體滲透系數(shù)(氣密性)是導(dǎo)致水蒸氣擴(kuò)散的重要原因;膠層厚度與空氣內(nèi)外的水汽分壓差導(dǎo)致的水份擴(kuò)散是造成中空玻璃失去功效的重要因素。
Homogeneous polymer is usually used as sealant, but the polymer is not completely airtight. The fugacity difference (pressure difference or concentration difference) between the two sides of the polymer promotes the isothermal diffusion of the polymer. The main diffuser of sealant for hollow glass is water in atmosphere. The gas permeability coefficient (air tightness) of polymer is an important reason for water vapor diffusion. The water diffusion caused by the thickness of adhesive layer and the difference of water vapor pressure inside and outside the air is an important factor for the loss of effectiveness of hollow glass.

3.干燥劑的有效吸收水分的能力低
3. The ability of desiccant to absorb water effectively is low.
干燥劑不僅要將中空玻璃密封零件在安裝的時(shí)侯密封在中間層里的水分吸收，使中空玻璃形成合格的初始露點(diǎn)，還要不停的吸收透過(guò)膠層分散到大氣層里的水分，持續(xù)維持合格的露點(diǎn)。
The desiccant not only absorbs the moisture of the insulating glass sealing parts in the middle layer during installation, so that the qualified initial dew point of the insulating glass can be formed, but also continuously absorbs the moisture dispersed into the atmosphere through the rubber layer, and maintains the qualified dew point.
如干燥劑吸收水分的功能差，無(wú)法有效地吸收擴(kuò)散到大氣層里的水份，就會(huì)使得水份聚集在大氣里，水分壓提升，中空玻璃的露點(diǎn)升高。
If the desiccant has a poor function of absorbing water and can not effectively absorb the water diffused into the atmosphere, it will make the water accumulate in the atmosphere, raise the water pressure, and raise the dew point of the hollow glass.
