在使用胶粘剂时,我们该如何选择固化速度更适合自已生产工艺要求的胶粘剂?

  胶粘剂在很多地方口语化简单叫做:水,它在日用领域比较简单,一般的502胶水大家可能都有接触,还有多一点的可能就是粘鞋子的胶水,而应用得多的是工业或者工程中的胶粘剂,这类胶粘剂一般都是在工厂或者项目中使用,用量就不像家庭,一般都是按公斤或者成吨来使用的。对于大量使用胶粘剂来说,胶粘剂的固化速度对操作方便性就显得十分重要了,那么应该如何选择胶粘剂的固化速度,什么样的固化速度才对自己用胶比较科学和方便呢?

  1、所选择的胶粘剂需要具备足够的工作时间(晾置时间、有效时间),才能适当混合和喷涂或涂抹胶粘剂,以及装配粘合的部件。
  2、如果是较小的组件或较短周期时间那么生产工艺能够使用具有短时间快速固化定位的胶。如果是大型组件则要考虑足够的组装时间。

  所以实际选择胶粘剂时不能一味的讲究快慢,而应该结合自己的产品或设备选择好涂胶设备和方法,再在这个基础上去选择合适的胶水来施工。

Adhesive is colloquially called glue in many places. It is relatively simple in daily use. You may have contact with the general 502 glue, and a little more may be the glue used to stick shoes. The adhesives used in industry or engineering are mostly used in factories or projects, and the dosage is not like home, They are usually used in kilos or tons. For a large number of adhesives, the curing speed of the adhesive is very important for the convenience of operation, so how to choose the curing speed of the adhesive, what kind of curing speed is more scientific and convenient for their own use?

1. The selected adhesive needs to have enough working time (air time, effective time) to properly mix, spray or apply the adhesive, and assemble the bonded parts.

2. If it is a smaller component or a shorter cycle time, the production process can use glue with a short time and rapid curing positioning. If it is a large component, consider enough assembly time.

3. The time for pressure alignment and clamping is required. The time for pressure alignment of large components will be longer. The operation of actual workers should be considered. If the operation time is within 30 minutes, the application period of the glue you choose should be at least 1 hour. Otherwise, the operation is not timely, and the glue has been initially fixed, which will affect the quality of the whole product.

Therefore, the actual choice of adhesive can not blindly pay attention to the speed, but should be combined with their own products or equipment to choose a good coating equipment and methods, and then on this basis to choose the appropriate glue to construction.
