1. After scrubbing, there will still be a layer of moist water and moisture adsorbed on the bonding surface of the PE water supply pipe after cleaning. It is difficult to ensure that the bonding surface is dry. float.
2. The bonded PE pipe soaked in water is in a fully closed state, and its shear strength is reduced due to the limitation of curing and volatilization conditions.
3. If sediment, rainwater and other sundries adhere to the surface of the pipe fittings, it will bring certain difficulties to the processes of cleaning, chamfering, emery cloth roughening, etc. I still hope that you will avoid such problems during the bonding process. bad weather.
4. Try not to choose PE pipe welding construction in rainy weather. If you really need to weld in rainy days, you should use an umbrella to cover the welded pipe opening to avoid water stains remaining on the PE pipe.
5. Due to the cold weather during welding in winter, it is necessary to control the temperature of the PE pipe hot-melt welding machine and adjust the time to make the temperature higher than that of the summer welding machine, and the hot-melt time is longer than 3/1 of the summer time. .
