When it comes to the operation of hot melt adhesive machines, we have not elaborated in detail in the operation manual for a long time. There are strict regulations on how to operate and maintain the machine equipment correctly and effectively. Many times, it is possible that significant equipment damage is caused by improper operation by humans, such as the rupture of hot melt adhesive hoses, the entry and exit of glue spray heads, and stains on the work platform. Today, we mainly talk about under what circumstances hot melt hoses may burst.
Mainly in terms of temperature, under normal circumstances, for the hot melt adhesive machine insulation throat pipe with a Teflon (mainly referring to PTFE) inner liner, assuming the internal adhesive pressure of the throat pipe is 8.6Mpa, if a common Teflon inner liner hot melt adhesive machine insulation throat pipe is used, the general operating temperature is between 150℃ and 180℃ If the temperature is even higher, it is prone to pipe burst or loosening of the threaded joints at both ends, as well as leakage of rubber. The maximum operating temperature of the throat tube with high-quality Teflon inner liner is within the range of 232℃. The maximum operating temperature is inversely proportional to the pressure of the hot melt adhesive inside the pipe. The higher the operating pressure, the lower the maximum operating temperature will be accordingly.
