Gap between the interface of plastic tube is aligned the end face of two plastic tubes, is then held out against with manpower or mechanical pressure described
Plastic tube clamps the sheet metal, and the plastic tube junction at both ends is made to melt, will be two after the condensations of t after a period of time
The plastic tube is bonded in the sheet metal both ends；
Or selection electrified regulation metal electric heating sheets：The metal electric heating sheets are put into connecing for two plastic tubes when bonding
Gap between mouthful is aligned the end face of two plastic tubes, and then holding out against the plastic tube with manpower or mechanical pressure clamps
The metal electric heating sheets connect the metal electric heating sheets power supply, make the metal electric heating sheets heat production, make the described of both ends
Plastic tube junction melt, through t after a period of time condensation after will two plastic tubes be bonded in metal electric heating sheets both ends.
The time t in step 3) is 10~200s.
Operating voltage is 36 volts of safe voltages below when being powered to the metal electric heating sheets in step 3).
The present invention has following positive beneficial effect：
1) present invention is applicable not only to the tubing of big wall thickness, is also applied for the very thin tubing of wall thickness, tubing wall applicatory
Thickness is 3mm or more；Compared with traditional handicraft, 70% or so can be declined using cost of the present invention；And energy conservation and environmental protection, sweat soldering
Time is short, and speed of application is fast, simple for process；
2) since the plastic tube at after energization plus both ends constantly melts and can be evaporated surface moisture, the modeling at both ends is not influenced
Expects pipe merges, and can be constructed with submersible；
3) Joining Technology of the invention is higher than the intubation bonding strength of machined pressure jacking, is well suited for having in gully
Limit the connection low to bonding strength requirement such as job space and telecommunications plastic tube.
