Instructions:

Fire equipment powder coating production line is specially designed for the surface treatment of fire equipment (such as fire extinguishers, fire hydrants, pipelines, etc.), through electrostatic powder spraying technology to form ‌ high temperature resistance, corrosion resistance, fire retardant ‌ protective coating, meet the GB/T 14561, UL/CE and other fire industry standards. The production line integrates the functions of ‌ high-precision spraying, intelligent temperature control, environmental protection recycling ‌, which is suitable for batch painting of metal fire fighting equipment. Operation process for feeding ‌, ‌ pretreatment ‌ (sand blasting, degreasing and phosphating) to ‌ pure water cleaning ‌, ‌ ir preliminary drying ‌, ‌ robot spraying ‌, ‌ high temperature curing ‌, ‌ quality packaging. Comply with ‌NFPA 70E‌ (electrical safety), ‌ISO 12944‌ (corrosion protection grade C5-M) standards.
The powder is fire resistant through ‌UL 263‌ and supports custom RAL color cards/fluorescent coatings. ‌

Main structure and components:

1. Core equipment composition and function ‌
1. ‌ pre-processing system
‌‌ function ‌ : remove oil and rust on the surface of the spring, and enhance the adhesion of the coating. ‌ Equipment includes ‌ : sandblasting machine/shot blasting machine (surface roughness) degreasing tank (alkaline solution cleaning) Washing tank (rinsing residue)
Phosphating tank (added rust resistance, optional)
2. ‌ powder spraying system ‌
‌ electrostatic duster ‌ : The high voltage electrostatic generator is used to make the powder charged and uniformly adsorbed to the spring surface.
Adjustable gun Angle, air pressure and powder output, suitable for different spring shapes.
‌ powder supply center ‌ : store and circulate powder, equipped with sifter to filter impurities.
3.‌ curing system ‌
‌ high temperature curing furnace ‌ : Temperature range: 180~220℃ (depending on powder type). Heating method: electric heating or gas heating, with hot air circulation function. Curing time: 10 to 30 minutes (make sure the coating is fully cross-linked).
‌ automatic conveying system ‌‌ suspension chain/conveyor belt ‌ : high temperature chain, bearing spring workpiece through each process.
The speed can be adjusted (1~5m/min) to match the production rhythm.
4. ‌ powder recovery system ‌
‌ cyclone separation + filter element recovery device ‌ : recovery rate ≥95%, reduce powder waste. Equipped with pulse blowback device to prevent blocking of filter element. ‌ Intelligent control system ‌PLC+ touch screen centralized control, real-time monitoring of temperature, wind speed, spraying parameters. Fault alarm and data recording function, support process parameters cloud storage.
