PTFE hose extruder is a kind of equipment used to produce polytetrafluoroethylene (PTFE) hose. The equipment adopts the extrusion process, heats and melts PTFE particles and extrudes them into hoses of various specifications through a die. In the production process, the commissioning of the PTFE hose extruder is a very important step, the following is an article about the commissioning of the PTFE hose extruder.
Preparation
Before commissioning the PTFE hose extruder, some preparatory work is required. First of all, it is necessary to check that the machine is installed correctly, that the power supply is connected, and that all electrical equipment is working properly. Second, check that the correct PTFE pellets are added to the melt tank, and check that the heater is working properly. Finally, check that the cooling system is working properly.
Debugging process
(1) Adjust the temperature
In the debugging process of the PTFE hose extruder, the temperature needs to be adjusted first. The PTFE pellets need to be melted into a liquid state to be extruded into a hose, so the heater needs to be adjusted to the correct temperature. When adjusting the temperature, it should be noted that the melting point of PTFE particles is 327°C, so the temperature of the heater should be set between 330°C and 350°C.
(2) Adjust extrusion speed
After the temperature is adjusted, the extrusion speed needs to be adjusted. The adjustment of the extrusion speed needs to be determined according to the specifications and requirements of the hose. Normally, the extrusion speed of the hose should be between 10mm and 20mm. When adjusting the extrusion speed, it needs to be adjusted according to the actual situation to ensure that the quality of the hose meets the requirements.
(3) Adjust cooling speed
After the hose is extruded, it needs to be cooled to ensure the quality of the hose. The adjustment of the cooling rate needs to be determined according to the specifications and requirements of the hose. Normally, the cooling speed of the hose should be between 5m/min and 10m/min. When adjusting the cooling rate, it needs to be adjusted according to the actual situation to ensure that the quality of the hose meets the requirements.
(4) Adjust the mold
During the commissioning process of the hose extruder, it is also necessary to adjust the mold. The adjustment of the mold needs to be determined according to the specifications and requirements of the hose. Typically, the diameter of the mold should be the same diameter as the hose, and the hole diameter of the mold should be the same wall thickness as the hose. When adjusting the mold, it needs to be adjusted according to the actual situation to ensure that the quality of the hose meets the requirements.
end work
After finishing the commissioning of the PTFE hose extruder, some finishing work is required. First of all, the machine needs to be cleaned for the next use. Secondly, the parameters in the debugging process need to be recorded for reference in the next use. Finally, a quality inspection of the hose is required to ensure that the quality of the hose meets the requirements.
In short, the commissioning of PTFE hose extruder is a very important step. During the debugging process, it is necessary to pay attention to the adjustment of temperature, extrusion speed, cooling speed and mold to ensure that the quality of the hose meets the requirements. After the debugging, some final work needs to be done, and the parameters during the debugging process should be recorded for reference in the next use.
