中空玻璃用二道密封胶使用前应做哪些前期准备?

发布时间:2019/07/03    发布人:

为保证注胶加工的质量░,双组份打胶机建议中空玻璃二道密封胶(简称中空胶)使用之前要做以下准备:
In order to ensure the quality of injection processing, the two-component glue maker suggests that the following preparations should be made before the use of hollow glass two-way sealant (hollow glue for short):
a:使用环境和养护环境的要求:中空胶注胶区应清洁•●、无尘•●、通风░,温度保持在10℃一40℃░,相对湿度40%一80%;使用前中空胶本身的温度应不低于10℃░,在冬季存储温度比较低时░,使用前应置入暖房数日后再使用;同时░,中空玻璃养护区的温度应不低于10℃。
A: Requirements for use and maintenance environment: Hollow glue injection area should be clean, dust-free and ventilated, the temperature should be maintained at 10-40 C and the relative humidity should be 40-80%. The temperature of hollow glue itself should not be lower than 10 C before use, and when the storage temperature is relatively low in winter, it should be placed in the heating room for several days before use, at the same time, hollow glass should be maintained. The temperature in the zone should not be less than 10 C.
b:基材表面的要求:所有的基材被粘部分都应进行清洗░,除去灰尘░,油污或其它污物;采用离线低辐射镀膜玻璃加工制作中空玻璃时░,其边部封胶区要先进行除膜处理。
B: Requirements for the surface of the base material: All the adhered parts of the base material should be cleaned to remove dust, oil or other dirt; when making hollow glass by off-line low-radiation coated glass processing, the edge sealing area of the base material should be removed first.

经验分享:中空胶的固化是化学反应过程░,温度对其固化过程有较大的影响░,合适的使用环境和养护环境是保证中空胶佳的固化与粘接性能的重要环境因素。污物•●、灰尘会影响到终粘接性能░,因此░,对被粘基材表面一定要进行清洗。低辐射镀膜玻璃的膜层与结构胶的相容性较差░,加工过程中建议将镀膜玻璃先进行除膜处理░,以保证中空胶与玻璃粘接良好。
Experience sharing: The curing of hollow adhesive is a chemical reaction process. Temperature has a great influence on its curing process. The suitable use environment and maintenance environment are important environmental factors to ensure the best curing and bonding properties of hollow adhesive. The dirt and dust will affect the final bonding performance. Therefore, the surface of the bonded substrate must be cleaned. Low radiation coated glass has poor compatibility with structural adhesives. In order to ensure good adhesion between hollow adhesives and glass, it is suggested that the coated glass should be removed first in the process of processing.
