How To Remove The Residual Glue From Teflon Tape

- Aug 21, 2017 -

After Teflon tape was baked high temperature will be appeared residual glue, overflow glue and other phenomena, through the feel or close observation will find a small residue, this tiny residue on the production has a great impact. This phenomenon may be due to the high temperature of the tape data does not meet the production requirements, usually require high temperature requirements in the 210-260 degrees, so the production should be confirmed before the production requirements.

If the temperature of the production line is too high, not within the scope of the process requirements, there will be residual glue, should check the temperature sensor is normal; Teflon high temperature tape product itself quality problems in the coating production process if not strictly Sensitive rubber baking data for curing curing, curing time is not enough or too fast coating line, will lead to glue, primer glue, the substrate can not be combined with the three components; when Teflon tape coated by the coating machine After the rubber coating, semi-finished products generally need to stand for 2-3 days before the rewinder cutting use, this is mainly to make the glue and the substrate fully integrated, glue in the natural state of complete curing, if not completely Curing on the rewinding cut, there will be residual glue.

For the phenomenon of residual glue, the first and most critical is to control the quality of Teflon tape, put into production before the ozone should be the first high-temperature screening test to meet the requirements of the company before use.

As Teflon tape is a high-tech process, in the production process of raw materials contain chemical composition, and each customer use the environment, painting equipment, technical requirements, production processes and personnel operations and many other factors in the production process It will inevitably be abnormal phenomenon.

If there is a phenomenon in the production process of residual glue, should be the first part of the workpiece removed, stored separately, in order to avoid the re-emergence of such phenomena, should increase the intensity of online products, through a period of time or a certain number of bad statistics, The percentage of residual rubber rate, should also be based on the actual situation of this batch of tape to check to find out the root cause of the problem, so that the production process will not be a similar phenomenon.

In order to reduce the cost of the workpiece, the workpiece can be used alcohol or tape to remove the glue, the method is to use a small amount of alcohol to wipe the cotton; use the same type of tape for sticky.
