Loose glue means that in the dispensing process, the glue does not flow according to the preset path and shape, resulting in uneven glue water, abnormal shape, and insufficient viscosity. The treatment of loose glue can be started from the following aspects:
First of all, check whether the parameters of the dispensing machine are set correctly, including the flow rate, pressure, temperature and so on.
Secondly, check whether the viscosity of the glue meets the requirements, and the ratio of glue can be adjusted appropriately or the thickener can be added.
Finally, you can improve the fluidity and uniformity of the glue by adjusting the height, speed, Angle and other parameters of the dispensing head, or using different dispensing heads and needles to achieve a better dispensing effect.
Loose glue means that the glue is not sprayed in accordance with the preset path, but there is a deviation or overflow. For the case of loose glue sprayed by the dispensing machine, the following measures can be taken to deal with it.
First, the Angle or spacing of the nozzle can be adjusted to avoid deviation during glue spraying.
Secondly, parameters such as the viscosity, pressure or speed of the glue can be adjusted to ensure that there is no overflow when the glue is sprayed.
In addition, regular cleaning and maintenance of the nozzle is also one of the important measures to avoid loose glue.
Under normal circumstances, you can choose to recycle and reprocess.
