RSB-108 Aluminum Alloy Cleaner Industrial Application Case

1. Problem (Core Production Pain Points for Aluminum & Galvanized Parts Manufacturers)

1. Composite stubborn dirt cannot be fully removed: Transmission housings, oil pans, drive shafts and aluminum castings accumulate cutting oil, stamping grease, metal powder, hand sweat and inorganic salt residues. Ordinary cleaners lack strong penetration and dispersion, leaving hidden contaminants that lead to defects in subsequent painting, assembly and anodizing processes.
2. Corrosion and matte discoloration on aluminum alloy surfaces: Strong alkaline or acidic general cleaners easily etch aluminum substrates, causing surface dullness, dark spots and pitting; conventional protective additives fail to protect LY12 hard aluminum, resulting in high reject rates.
3. Excessive foam leads to incomplete rinsing: High-foam cleaning agents produce thick foam during ultrasonic and spray washing, leaving chemical residues and water marks on aluminum workpieces, requiring repeated rinsing and extra labor costs.
4. Poor environmental compliance of conventional cleaners: Many competing products contain phosphorus, heavy metals, chromate, nitrite and other restricted hazardous substances, failing wastewater discharge standards and export RoHS audits.
5. Unstable cleaning efficiency under high & low temperature conditions: Common cleaners stratify or precipitate at high or low temperatures, leading to inconsistent cleaning results in seasonal production environments.
6. Narrow material compatibility: Most single-function degreasers cannot clean both aluminum alloy and galvanized workpieces simultaneously, forcing factories to stock multiple cleaning chemicals and raise inventory management costs.
