Some aluminum manufacturers make glue-injection broken bridges For aluminum profiles, the glue strips used may have uneven colors. So why is this? Let’s analyze it below.
The color of the heat-insulating adhesive strip is uneven, which is mainly manifested by the obvious color on the surface of the strip after the strip is cured during the injection process. Uneven. The reason is that the mixing blade speed of the mixing head is reduced, resulting in uneven mixing. Glue metering ratio fluctuates, Glue A is left for too long, expires, etc. The solution is to listen to the sound of the mixing motor to see if there is any change. If there is any change, check whether the pressure of the hydraulic station has dropped, whether the oil temperature has increased, and whether the pipeline is blocked. Use a tachometer to measure the rotation speed and check the mixing blade to make a judgment. Deal with the situation you find. If you cannot handle it yourself, you should ask a professional to solve it. Check whether the proportioning wheel is slipping and check the expiration date on the label of the raw material barrel. It may also be that the glue has been stored for too long and the color has changed after stirring. Evenly, the solution is to replace with new glue.
