How to keep clean 15,733,750,102 Longnan acoustic tube to the former Gansu acoustic tube adhesion test must be assembled, clean acoustic tube insertion Longnan Longnan acoustic tube end appearance 50mm length and Gansu acoustic pipe inner wall bearing interface around, and then coated with cotton scrub once, and then coated with a layer of adhesive between the adhesive surface with a brush evenly coated not leak. Tu Bi ideal combination that is rotated to an angle, the acoustic tube inserted into the Order of Longnan Longnan interface acoustic pipe, with a mallet percussion, acoustic tube so Longnan fully inserted socket, not disassemble or change the direction in two minutes timely wipe out the glue joints to keep Longnan acoustic pipe cleaner. Li Longnan Acoustic Pipe expansion joints installed on each one, to compensate for the acoustic tube countercurrent Longnan thermal expansion and contraction. At the time of installation, pay attention to the direction of sailing, easy to install when the natural formation of the cross-slope Longnan acoustic tube. Then, after the amount of Longnan acoustic tube length to take a decision, http: //www.jcgxx.com/ can manually cut with a hacksaw saw or circular saw blades, sawing cutting saws, pay attention to both ends of the incision should remain flat, with butterfly dwarfish remove burrs and chamfer, chamfer should not be too large. Again, the test must be carried out prior bonding assembly, and then in both adhesive surface coated with an adhesive with a brush evenly coated attention not leak. In addition, after James finished the ideal combination to rotate the angle of the acoustic tube inserted into the Order of Longnan Longnan interface acoustic pipe, with a mallet percussion, acoustic tube so Longnan fully inserted socket. The above is for a Longnan acoustic tube construction technology knowledge introduction, I hope we can learn about this knowledge.
