After the teflon tape manufacturer's teflon tape is roasted at high temperature, there will be residual glue, glue overflow and other phenomena. Through hand feeling or close observation, it will be found that there are tiny residues, which have a great impact on the production.
This phenomenon may be that the high-temperature resistance data of the tape does not meet the requirements of production. Generally, the required high-temperature resistance is 210-260 degrees. Therefore, it should be confirmed whether the tape meets the requirements of production before production.
If the temperature of the production line is too high, not within the scope of the process requirements, there will also be residual glue, should check whether the temperature sensor is normal;
Teflon high temperature adhesive tape itself has quality problems. In the process of coating production, if temperature curing is not carried out in strict accordance with the baking data of pressure sensitive adhesive, the curing time is not enough or the coating line speed is too fast, the glue, the bottom glue and the base material cannot be combined.
As teflon tape through the coater coating glue roll coating, semi-finished products are generally need to rest for 2-3 days only after rewinding cutting use, exist mainly in order to make a combination of glue and base material, glue cured under natural state, if there is no completely curing for rewinding cutting, can appear the residual gum.
For the occurrence of residual adhesive phenomenon, the first and key thing is to control the quality of Teflon tape. Preliminary high-temperature ozone screening test should be carried out before putting into production to meet the requirements of the company before use.
Because teflon tape is a high-tech process, the raw materials in the production process contain chemical components, and each customer's use of the environment, coating equipment, technical requirements, production process and personnel operation and other factors, in the production process will inevitably appear abnormal phenomena.
If it is in the process of production in the residue phenomenon, should first remove abnormal artifacts, stored separately, in order to avoid to appear this kind of phenomenon, dealing with the online product increased inspections, through a period of time or a certain number of bad statistics, analysis of the rate of residual gum percentage, still should according to the actual situation for inspection of this batch of adhesive tape, find out the root cause of the problem, so in the process of production will not appear similar phenomenon.
For the workpiece residue, in order to reduce the cost of investment, can use alcohol or tape to remove adhesive, the method is to use a small amount of alcohol dipped in cotton cloth to wipe;
Use the same type of tape for removal.
