Problems solved by technology

[0002] Ordinary fire-fighting galvanized pipes and connectors have many problems in actual use due to their poor performance in terms of anti-corrosion, anti-scaling and anti-bacterial properties, coupled with the characteristics of long-term static and emergency use of fire-fighting water: First of all, due to the poor anti-corrosion performance of galvanized steel pipes and long-term erosion by water, the inner surface of the pipes is prone to rust, and the nozzles are easily blocked after the rust layer falls off; secondly, after the inner surface of the pipes is scaled, the inner diameter of the pipes is likely to shrink or be blocked. The water delivery and air volume are reduced to the point that it cannot be delivered, which affects the actual use effect; moreover, the most critical point is that if the above-mentioned situation occurs during the fire-fighting and disaster relief process, the consequences will be unimaginable if the disaster relief is delayed; the existence of the above-mentioned defects makes the galvanized pipe The service life is short, generally only 5-8 years
[0003] In order to solve the problem of plastic-coating of fire-fighting pipes, many manufacturers have taken action. Some directly use polyethylene powder coating plastic-coated steel pipes to make fire-fighting pipes, but the adhesion is very poor.

Abstract

The invention discloses a special powder coating for plastic coating of a fire-fighting galvanized pipeline, which comprises 55-75% of a thermosetting resin, 3-5% of a curing agent, 15-35% of a pigment and a filler, and 3-5% of an assistant. The invention has the following beneficial effects: according to the technical scheme, the performance requirement can be met through one-time baking and curing, and the labor production efficiency of coating is high; powder coating which is not sprayed during coating can be recycled, and the utilization rate of the coating is very high and can reach 99% or above; and compared with a hot galvanizing fire-fighting pipe, the powder coating plastic-coated fire-fighting pipe is more environment-friendly.
