In real life, there are a lot of quick-drying glue, which hardens even in a few seconds, such as 502 glue. These glues are suitable for those bonding operations that are relatively small in size and relatively short in time.
      However, in many cases, the adhesive needs a long operation time (the operation time is the applicable period of the adhesive, generally several tens of minutes, which is related to the amount of the adhesive, and the more the adhesive is used at one time, Because the adhesive will condense, the operation time is shorter, such as those that have a relatively large operating range (several square meters) and high operational performance requirements (need to pressurize the bonding surface).
      If these adhesives are cured at room temperature, the curing time is longer (the curing can be carried out in the next step after 24 hours, and the curing is generally 5 to 7 days). Therefore, in order to accelerate the curing, the curing is generally carried out on the material standard. Generally, it has been stipulated that curing at 80±5 degrees Celsius for 1~1.5 hours can achieve complete curing.
    In fact, there is another type of accelerated curing, that is, heating and curing can proceed to the next process. Why is this proposal proposed? Occasionally, the heating device is used for a long time, and the temperature uniformity of the device is deteriorated, and the standard curing parameters cannot be achieved. At this time, in order to accelerate the curing, it is not required to completely cure, and only the next process is required. So how do you accelerate the curing? It has been proved by experiments that curing at 60 degrees for 1~1.5 hours (for example), and the performance at room temperature for 24 hours is equivalent, the curing temperature range can be changed to 60-87 degrees for 1~1.5 hours, without changing the equipment. Accelerate curing without affecting manufacturing progress.
