Pre-treating metal surfaces is an essential task in many industrial applications. Also called phosphatizing, metal surface pre-treatment prevents rust and corrosion from adhering to metal surfaces as well as prepares metal surfaces for the application of primer, paint, or powder coating. Painted or powder coated metal surfaces that have not been pre-treated often contain defects in the finish. Therefore, metal surfaces must be pre-treated to ensure the quality of fabricated metal pieces and other applications. The most efficient method of which is using Daimer®’s phosphatizing pressure washers.
In phosphatizing, acids and aggressive solvents are used to remove all dirt, oil, film, and more. A thin layer of iron phosphates permanently remains on the metal surface to offer protection.
Daimer®’s Super Max ® AF phosphatizing pressure washers are the most effective and powerful phosphatizing pressure washers available. These pressure washers come with a variety of options, so that industrial users can select the machine that best suits their application. Some of these options include: pressure levels ranging from 700 psi to 3000 psi; flow rates ranging from 2 GPM to 5 GPM; electric, gasoline, or propane engines; and 1.5 HP to 20 HP NEMA motors. All of these Super Max ® phosphatizing pressure washers are triple-function machines; meaning they can function independently as steam, cold water, and hot water pressure washers.
All Super Max ® AF series pressure washers come standard with Daimer®’s robust phosphatizing system. This system uses downstream injection, the most common method in the injection of acids and aggressive solvents for metal pre-treatment. This type of injection ensures that the strong chemicals only contact the injector, high-pressure hose, trigger gun, wand, and nozzle; all of which are easy to protect against the corrosive nature of the acids.
