What is second-generation chromium-free passivation for aluminium profile?
Changzhou Junhe Technology Stock, a pioneer in the field of treatment before coating, relies on the ability and operation through technology leadership, and has been constantly pushing users to achieve better and more durable anti-corrosion performance of products, while also continuously promoting process optimization.
Junhe has achieved chromium-free aluminum profile industry and reduced water consumption by more than 50% after the introduction of chromium-free process for waterless washing aluminum profiles. Continuous technical innovations of this second-generation chromium-free process help users avoid the use of water and discharge wastewater during the production process.
Development history of Junhe aluminum alloy chromium-free passivation process
Application of the second generation waterless washing process
Vertical line: three process slots
Product application: Treatment of extruded profiles
Base material: extruded profiles 6061 and 6063
Pre-treatment method: Vertical waterfall type
Chain speed: 2-5m/M
Performance requirements:
Types 1 and 2 powder: AASS, 1000h
Type 3 powder: AASS, 2000h
Vertical line process
Advantages
Economic benefits: Water and electricity can be saved, and the comprehensive cost savings will reach more than 35 yuan/ton profile. The initial environmental protection equipment investment will be reduced by 90% for a newly built factory.
Environmental benefits: Waterless washing, low acidity, and simple wastewater treatment.
Workshop environment improvement: Low acidity, less odour, no residue, and more friendly workshop environment.
Simpler process operation: High etching can be easily achieved, so as to completely solve the problem of acid and alkali residue, etc.
