Segmented Process Special
Anodizing
Supply basic aluminum anodizing chemicals, colorants and sealing agents with stable ion concentration. Matched with oxidation bath process debugging, film thickness control and EU environmental regulation review for automotive aluminum parts and 3C precision aluminum production lines.
Pickling & Alkaline Degreasing
Supply composite pickling liquids and concentrated alkaline degreasers, customizable compound systems based on workpiece rust degree and oil type. Suitable for pre-treatment of carbon steel, stainless steel, aluminum and zinc alloys, controlling bath corrosion rate and reducing substrate over-etching risks.
Metal Anti-Corrosion Passivation
Supply chromium-free conversion coating agents, low-chromium passivation liquids and rust sealing auxiliaries under strict low heavy metal control standards, matched with salt spray and weather resistance testing for outdoor hardware and auto parts anti-corrosion working conditions.
Machining Cutting Fluids
Supply emulsified cutting fluids and semi-synthetic grinding fluids for steel and aluminum cutting, drilling and grinding processes to suppress tool wear and reduce processing heat, with synchronous supply of bath bacteriostatic and defoaming auxiliaries.
Etching & Paint Stripping
Supply compound metal etching chemicals and water-based paint removers with controllable etching depth and stripping speed for signage, precision hardware etching and workpiece renovation paint stripping production lines.
Circulating Water Treatment
Supply biocides, pH regulators and defoamers for surface treatment production line circulation tanks and wastewater treatment systems to stabilize bath operating parameters.
