Method for husking the coating of anticorrosive spiral steel tube


The peeling technique of anticorrosive spiral steel tube coating is proposes on the idea of finishing and analyzing the structure and coating method of 3PE anticorrosive coating.Anticorrosion of spiral steel pipe coating husking primarily has 2 styles of circumstances, may be at temperature (20 ℃ + five ℃) and fifty ℃ + / - 5 ℃ temperature husking.


Normal temperature husking and extreme temperature stripping.Normal temperature husking is typically distributed at temperature, which needs 100N/cm. The fashioned pipe is cooled to temperature when water flowing out. The pipe contemporary out of water encompasses a high demand on the rubber layer for testing, which may be glad by well-known domestic makers currently.


2, ought to place the anticorrosive spiral steel pipe heating to fifty ℃ + / - five ℃ or on top of, quite seventy n/cm.Specific experiments shall be subject to party a's standards.However, if the temperature is just too high, the subsequent issues can occur: epoxy powder set reaction is just too quick, powder melting isn't ample, poor film formation, can scale back the power to bond with the surface of spiral steel tube;Before the adhesive coating, the purposeful teams of epoxy glue were overly consumed, and a few or all of them lost the bonding ability with the adhesive.The coalesced epoxy powder layer could also be slightly coked, showing a dark and yellow color, leading to unqualified coating husking check.

  • Description of application effect

Channel steel is a long strip of steel with concave section. It belongs to carbon structural steel used in construction and
machinery.
Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
Channel steel is divided into ordinary channel steel and light channel steel.
Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed tray cabinets,
etc. Channel steel is often used with i-beam.
Channel steel can be divided into 4 types according to the shape: cold bending equal-edge channel steel, cold bending
non-equal-edge channel steel, cold bending inner coil channel steel, cold bending outer coil channel steel.
