0010010 nbsp; 0010010 nbsp; 0010010 nbsp;Window glueThe amount of use in packaging and industrial production is relatively large, because the characteristics of window adhesives cure faster, and it is also more convenient to use, but in actual use, it may happen that the window adhesives cannot be cured normally. It is much slower than normal curing, so what are the reasons for this situation? Today Shandong Ruiyi Yinghua New Material Co., Ltd. will come to analyze it for you.
0010010 nbsp; 0010010 nbsp; 1. The relative humidity of the use environment is low (less than 40%), which causes the surface to be too dry, so it is not easy to cure faster.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2, the adhesive is an acidic surface (pH ＜ 7), it can also cause slow curing Can not be cured.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3, some tolerance changes will cause the bonding gap to be greater than 0. 25 mm, more need for large gaps Filled with colloids, the more acid stabilizers in the colloid, the curing speed of the polymerization reaction will slow down or lead to incomplete curing of window adhesive.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When we use window adhesives and the above-mentioned situations cannot be cured quickly, we can do the following:
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1. Before using window glue for bonding, parts should be exposed to atmospheric humidity for a long time to make the air The moisture is balanced with part of the surface.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2, when low humidity cannot be controlled, try a compatible accelerator on one surface to neutralize the window Acid stabilizer in glue.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3. If it is an acidic surface, artificial curing conditions can be provided, such as the use of surface treatment agents. Alkaline substances accelerate the curing of the glue, and acidic substances slow the curing of the glue.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 4, use window glue accelerator, which can be used to better strengthen the curing speed and gap filling ability of window glue .
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; the above is the method that the window adhesives summarized by Shandong Ruiyi Yinghua New Materials Co., Ltd. cannot be quickly cured and solved. For products with a relatively large amount of use, if the curing time is longer, it will affect our production efficiency. Therefore, when we use the above method to solve the problem, we must also buy products with quality assurance.
