Fengfan Degreasing Agent Electroplating Chemicals Metal Surface Treatment Auxiliary Agent 896

Product Overview

Fengfan 896 is a white alkaline powder for cleaning metal before plating. Mixed with water at the strength the job calls for, it strips drawing oils, machine grease, handling marks and polishing residues from the surface, so the next tank meets bare metal instead of an oily film. Within the family of coating production chemicals, this is the step that quietly decides how everything after it behaves.

The product is supplied as five formulation types rather than one universal grade. Two are built for steel, two for non-ferrous metals, zinc-aluminum alloy and aluminum, and one for parts that arrive with polishing cream on them. Three work by chemical immersion; two are electrolytic, using current to shorten the cycle and reach into recesses that a still bath cannot clear.

It comes as a powder in sealed woven sacks and is dosed by weight per tank volume, which keeps freight and storage compact compared with a ready-mixed liquid. Plating shops, job shops and in-house finishing departments use it as the first tank in industrial electroplating, ahead of derusting, activation or the plating bath itself.

Key Features

• Fast on mixed soils. Drawing oil, cutting fluid, grease, fingerprints and buffing residue come off in a single short cycle, so parts move on without a second wash.
• Runs at ordinary temperature. Types A and B begin working at ambient temperature, which means a shop without tank heating can still run a full degrease; heat only shortens the cycle when the soil load is heavy.
• Wide metal coverage. Steel, iron, non-ferrous metals, zinc-aluminum alloy and aluminum are all handled by the range, which is why the same family turns up across industrial electroplating shops running mixed work orders.
• Low maintenance. There are no separate addition agents to balance: the bath is dosed with the same powder, topped up against a measured concentration and kept clean, which is how the steadier plating chemicals in a line are managed.
• Built for output. Cycles are short enough not to become the bottleneck, and the product suits batch tanks and continuous lines alike.
• A companion for polishing cream. Where buffing compound is the main soil, type E and a dedicated removing-wax agent cut through it faster than a general-purpose cleaner.

Formulation Types A-E

Use Scenarios

• Automotive component manufacturing. Steel brackets, fasteners and zinc-aluminum castings are degreased before the plating process starts, so the protective layer keys to clean metal rather than to a film of press oil.
• Electronics plating shops. Copper and other non-ferrous parts go through an electrolytic degrease first, which gives the uniform soil removal that small connectors and stamped contacts need before metal electroplating.
• Decorative hardware and polished parts. Components straight from the buffing wheel carry polishing cream that general cleaners simply smear; type E is built for that residue.
• Job shops with mixed work. Steel and aluminum are both covered by the family by switching type and concentration, which suits shops that never run the same substrate twice in one day.
• Pretreatment before coating and painting. Parts cleaned and rinsed here come out water-break free, ready to move on to the coating production chemicals that follow: phosphating, conversion coating or paint.
• Continuous and high-volume lines. Batch tanks and continuous production are both served, so a line moving from job work to steady throughput does not have to change its cleaning chemistry.

Chemical and Electrolytic Methods

Three of the five types work by immersion alone. The part hangs or sits in the tank, the bath wets the surface and lifts the soil, and a rinse carries it away. There is no rectifier, no electrical contact and nothing to set beyond concentration and temperature, which makes these the simplest of the plating chemicals to run on a line that already has enough variables to watch.

The electrolytic types add current to the same job. Gas evolved at the part scrubs the surface while the bath works, so soil lifts out of blind holes, threads and recessed areas that a still bath struggles to reach, and the cycle shortens as a result. Results depend on clean racking and firm contact points; a part that is poorly contacted degreases unevenly. Within metal electroplating, this is often the step that decides whether a recessed part plates bright or shows a shadow.

In practice the difference comes down to geometry and volume. Open shapes with light oil run well as immersion work. Complex parts, tight recesses and high throughput justify the rectifier. Aluminum and zinc-aluminum components are handled by the lower-concentration electrolytic grade, so the bath cleans the surface without working on the substrate underneath.

Bath Make-up and Operating Steps

1. Clean the tank thoroughly and confirm the working volume before anything goes in; residue from an earlier bath skews the concentration.
2. Fill the tank to roughly two-thirds of the working volume with water.
3. Add the powder at the concentration listed for your type. The electrolytic non-ferrous grade runs at a lower figure than the rest, so check the table before weighing.
4. Top up to working volume and mix again, so the bath is uniform from top to bottom rather than strong at the bottom and weak at the weir.
5. Bring the bath to the working temperature listed for the type before the first load goes in.
6. Load the parts, or switch on the rectifier at the listed voltage and current for the electrolytic types, and process for the full cycle time.
7. Rinse thoroughly before the next stage, then check concentration and top up between loads so every batch entering the plating process downstream meets the same surface.

Company Background

• Founded in 1984. More than four decades in surface finishing, growing from a single plating operation into a developer and supplier of additives for industrial electroplating.
• A 67-acre site in Wuhan. The group's production base in Dongxihu District holds the additive plant, a pilot plating laboratory and the warehousing that feeds export orders.
• Research-led development. Work on greener electroplating chemicals sits behind patents and published technical papers, and the pilot laboratory lets a new process be tried on real parts before it reaches a customer's line.
• A range that spans the whole line. Pretreatment, zinc, copper, nickel, chrome and alloy plating, passivation and sealing come from one source, which simplifies sourcing for shops doing industrial metal plating across several stages.
• Recognition at home. Membership of the China Surface Engineering Association and a seat on its electroplating commission, plus a listing on China's National SME share transfer system.
• Export through Fengfan International Trade. The trading arm handles documentation, export packing and English-language communication, so technical and commercial questions sit in one conversation.
