中空玻璃结露会让产品的品质降低,影响正常的保温隔音效果,下面全自动封胶机厂家就给大家分析一下促使中空玻璃露点的升高的三种情况,希望对大家有所帮助!
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.密封胶挤压得太松或是里面有机械异物
1. Sealant is extruded too loosely or there are mechanical foreign bodies in it.
用两道弹性密封胶把中空玻璃与铝管间隔体结合在一起,一层使用丁基橡胶封存,第二层使用结构硅酮胶密封。在现实操作过程中密封胶里如果存在机械异物或是在涂胶时挤压得太松,导致胶体里面形成毛细管,并由于中间层里面和外面有压差或湿度差,大气里的水分进入中空玻璃中间层,导致中空玻璃中间层里的含水量升高。
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.水汽透过密封胶进到中间空气层里
2. Water vapor enters the middle air layer through sealant
一般使用均匀高分子聚合物作为密封胶,但聚合物也并非完全不透气,它两侧的逸度差(压差或浓度差促进了聚合物进行等温扩散。中空玻璃的密封胶的主要扩散物是大气里的水分,聚合物的气体渗透系数(气密性)是导致水蒸气扩散的重要原因;胶层厚度与空气内外的水汽分压差导致的水份扩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.干燥剂的有效吸收水分的能力低
3. The ability of desiccant to absorb water effectively is low.
干燥剂不仅要将中空玻璃密封零件在安装的时侯密封在中间层里的水分吸收,使中空玻璃形成合格的初始露点,还要不停的吸收透过胶层分散到大气层里的水分,持续维持合格的露点。
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.
如干燥剂吸收水分的功能差,无法有效地吸收扩散到大气层里的水份,就会使得水份聚集在大气里,水分压提升,中空玻璃的露点升高。
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.
