Galvanizing Fluxes
Zaclon LLC offers the widest available range of
solid and solution zinc ammonium chloride-based products, primarily used as
galvanizing fluxes. Zaclon® zinc ammonium chloride products are also used
by our customers for manufacturing other products, such as plumbing or brazing
fluxes and electroplating solutions.
Hot-dip galvanizing involves reacting metallurgically clean steel or iron
with molten zinc or zinc alloy.
The normal hot-dip galvanizing process involves a cleaning/degreasing step before
descaling or "pickling" in hydrochloric or sulfuric acid. After rinsing,
the treated surface is very active and forms light iron oxide layers rapidly.
Zaclon galvanizing flux dissolves the oxides that may form on steel or iron
preventing further oxidation before galvanizing.The flux also helps reactions
in the molten zinc by controlling formation of zinc oxides.
Fluxes are used as a "preflux", or solution flux and/or as a "topflux" or molten
salt flux floating on the liquid zinc metal. The fluxing process creates a metallurgically
clean steel or iron surface in the galvanizing kettle, allowing reaction with
molten zinc at about 825° F and the formation of a high quality, adherent
galvanized coating.
Zaclon Galvanizing Fluxes are available in granular and fine particle sizes.
Zaclon fluxes are made in a variety of zinc chloride to ammonium chloride weight
ratios, and with special additive packages for specific customer needs. These
products ship in 50 lb. bags.
Concentrated Zaclon solution fluxes are available in almost any ratio of zinc
chloride to ammonium chloride, and can be shipped in railcars, bulk trucks, bulk
drums or drums. Special solution fluxes with unique wetting agent packages and
other additives have been formulated for the needs of the continuous sheet and
wire galvanizing operation, including products thermally stable for preheating
up to 600° F.
Zaclon® Galvanizing Fluxes are widely used throughout the world for general job shop galvanizing for small parts, structures, tubes and pipe; and for continuous galvanizing operations for wire, fencing, sheet and tube. Zaclon® galvanizing fluxes are also used as building blocks for a wide variety of brazing, soldering, and welding fluxes.
Other Zaclon Specialty Fluxes
Zaclon LLC also produces specialty fluxes for specific
needs.
Sulfate Control Flux Solution is formulated with additives for the job
shop using sulfuric acid for pickling.
High Speed, Kleanrol, and Zaclon A-type Fluxes are used in continuous and batch hot-dip terne (lead-tin) and high-tin coating.
Zaclon ZR is a patented flux for operations using high aluminum zinc alloys, such as Galfan alloy from ILZRO (International Lead Zinc Research Organization) and "Galvalume" coating lines.
Zaclon AB is a low-smoke flux, often used for reducing zinc metal losses in zinc ashes.
