In the LED street light production, when we produce the chip package, the cup bubble occupies a large proportion, but the product in the production process if the bubble problem has not been a good solution or prevention, it will cause decay products a factor to accelerate the performance of IV to reduce the IR VF increased. So, any solutions for the existence of bubbles and plastic mixing full? Here we analyze from the few comments given by the people in the voltage for led lights industry.
Factors affecting bubbles, but do some engineering assessments, can be solved led high bay step by step. If there is a bubble cup, you can give a certain percentage of the plastic cup filling, and then proceeding to the next step process. The following relevant factors:
1. An environmental temperature and humidity had a greater influence on the bubble.
2. mold temperature is also generated a factor of the bubbles.
3. the formation of air bubbles and process adjustment.
For example, some factories there is no vacuum, no air bubbles, and even if the factories pumping vacuum bubbles, it should not be pumping vacuum. But the operating speed of skilled into a question of degree. And ambient temperature are also inseparable. Ambient temperature changes, we can take appropriate measures to control. If room temperature is 15 degrees, we must find ways to help glue the temperature reaches 60 degrees, so do the bubble cup should not occur again! Meanwhile, we should pay attention to many details in voltage for led lights. Such as tiny bubbles by eyes and subtle microscope can not see the drum pre-stick adhesive, but into the oven body, hot flatulence bubble expansion up.
Manually pre-Glue, brackets must be preheated. Preheat the pre-filling the AB material to swap the first two hours. As long as you keep the AB material, stents are hot bubble problem is not intractable. Encountered because of poor mobility, AB Cold, Cold bracket easily into the bubble. The operation should pay attention to the following question about voltage for led lights:
1. operating skills of the operator (the whole there are side air bubbles)
2. stick gum machine speed and the gel content is not well controlled (very prone to bubble place)
3. Machine is clean (this point will not cause air bubbles, but it is prone to the same thing similar to the ice, especially cyclohexanone)
4, To bracket the viscose, the drum speed is not fast.
5. change Glue, clean the rollers and led lights.
6. viscose machine.
