⚗️ Immersion-Type Alkaline Steel Cleaning Liquids – Production, Formulation and Properties

Overview:

Immersion-Type Alkaline Steel Cleaning Liquids are industrial cleaning solutions developed for removing grease, oil, wax, and machining residues from steel and ferrous metal surfaces.
They are designed for full or partial immersion systems, providing deep and uniform degreasing before coating, painting, or plating processes.
These cleaners combine alkaline builders, surfactants, and corrosion inhibitors to achieve strong cleaning power while protecting the base metal from oxidation.
They are commonly used in automotive, mechanical, and manufacturing industries where high-performance metal cleaning is essential for surface quality and durability.

Production and Formulation:

Immersion-type alkaline steel cleaning liquids are produced by blending alkaline agents, surfactants, chelating additives, and anti-corrosive compounds in deionized water.
The mixture is stirred until uniform clarity and pH balance are achieved.
The formulation’s alkalinity ensures effective breakdown of oils and greases, while surfactants provide wetting and emulsifying properties.
Corrosion inhibitors and stabilizers are added to prevent flash rusting and material damage.
Optional anti-foam and dispersing agents can enhance system performance and bath longevity.
The finished product is stored in alkali-resistant tanks and applied in heated or ambient immersion baths, depending on cleaning intensity requirements.

Properties:

• Appearance: Clear to slightly cloudy liquid

• pH Range: 10.0–13.0 (strongly alkaline)

• Density: 1.05–1.20 g/cm³

• Foam Level: Low to moderate

• Solubility: Fully water-soluble

• Odor: Mild detergent scent

• Shelf Life: 24–36 months

Advantages:

• Removes oils, waxes, and grease residues completely

• Provides deep and uniform cleaning in immersion systems

• Non-corrosive with protective additives

• Prepares surfaces for painting, coating, or electroplating

• Reduces contamination and residue formation

• Suitable for carbon steel, stainless steel, and alloy components

• Long bath life and economical consumption rate

Summary:

Immersion-Type Alkaline Steel Cleaning Liquids provide powerful degreasing and surface cleaning performance with excellent metal protection.
Their well-balanced chemical composition ensures safe, efficient, and residue-free results, essential for industrial finishing operations.
Ideal for mass production cleaning lines, these formulations are the backbone of modern alkaline surface treatment technology.
