1. PVDF pipe hot melt preparation work
Tool preparation: First, you need a set of special PVDF hot melt tools, including hot melt machines, cutting knives, cleaning cloths, fixtures, etc. Make sure all tools are clean and suitable for the PVDF material.
Material inspection: check PVDF pipes and fittings for damage and cracks, confirm size matching, and remember to use pipe fittings of the same material and wall thickness for connection.
2. PVDF pipe hot melt steps
1. Accurate cutting
Use a special cutting tool to ensure that the cutting surface is flat, vertical and free of burrs. The quality of the cut directly affects the welding effect, so the cutting must be careful and precise.
2, cleaning is key.
Use a cleaning cloth to thoroughly remove dust, grease and other contaminants from inside and outside the pipe ends. Any tiny impurities may cause welding defects and affect the sealing performance.
3. Preheating and alignment
Put the PVDF tube end into the heating ring of the hot melt machine, and set the appropriate heating time and temperature according to the tube diameter and wall thickness. When heated to a molten state, quickly take it out and immediately align it with another pipe section or joint, keep the two pipe ends completely attached, rotate it quickly and apply pressure gently to help the material spread evenly.
Key points of hot melt technique for 3. PVDF pipe
Temperature and time: Accurate control of hot melt temperature and heating time is essential. Too high or too long time will cause the material to decompose, too low or insufficient time may be welded. Adjust with reference to the parameters provided by the manufacturer.
Fast and accurate: From the hot melt machine to the docking, the action should be fast, try to complete within a few seconds to avoid cooling and hardening of the material.
Uniform pressure: When docking, apply pressure evenly to avoid deformation or internal voids caused by local overpressure.
Fixed cooling: After the welding is completed, use a fixture to fix the joint until it is completely cooled and solidified to avoid misalignment or leakage due to external force.
Inspection of 4. PVDF pipe after hot melting
After cooling, check the welding interface for defects such as flash, dent and crack. If necessary, a tightness test can be carried out to ensure the tightness of the connection.
