Let us learn how will Teflon high temperature cloth be baked at high temperature!
After the high-temperature baking of Teflon high-temperature cloth and teflon adhesive tape, there will be residual glue and overflowing glue. After the hand feel, it may be found that there are small residues in the close observation. This small residue has a great influence on the production. This phenomenon may occur because the high temperature resistance data of the tape does not meet the production requirements, and the required high temperature resistance is usually 210-260 degrees. Therefore, it should be recognized whether the production requirements are met before production.
In view of the phenomenon of residual glue, it is mainly the key to control the quality of teflon adhesive tape. Before starting production, the ozone should be tested at high temperature to meet the company's requirements.
Because Teflon high temperature cloth is a high-tech process, raw materials contain chemical components in the production process, and each customer uses the environment, coating equipment, skill requirements, production processes and personnel operations and many other factors in the production process. It is inevitable that an abnormal phenomenon will occur. If the temperature of the production line is too high, it is not within the scope of the process requirements, and residual glue will appear. Check whether the temperature sensor is normal. The quality problem of the Teflon high temperature tape product itself is not strictly in accordance with the pressure during the coating production process. The glue baking data is heated and solidified, the curing time is not good, or the coating line speed is too fast, which may cause the glue, the primer glue and the substrate to be combined.
When the teflon adhesive tape is coated by the coating roller of the coater, the semi-finished product generally needs to be allowed to stand for 2-3 days before the rewinding and slitting operation, mainly to make the glue and the substrate fully integrated. The glue is completely cured in the natural state. If the re-rolling is performed without complete curing, residual glue will appear.
If the residual glue phenomenon occurs during the production of Teflon high-temperature cloth, the abnormal workpiece should be taken out and stored separately. In order to avoid such a phenomenon, the online product should be intensified, and after a certain period of time, it may be a certain amount. Bad calculation, analysis of the percentage of residual glue rate, should also be based on the actual situation of this batch of tape to find out the source of the problem, so that similar phenomena will not appear in the production process.
