1. Chemical Transfer for Metal Cleaning Processes
Surface treatment starts with metal cleaning. And chemical hose delivers degreasers, alkaline cleaners, and acid solutions. Industrial-grade chemical hose resists corrosion from these harsh fluids. It transfers solvents and aqueous cleaners safely to tanks or spray systems. Choose PTFE or EPDM chemical hose for acid/alkaline resistance, critical for removing oil, rust, or oxides.
2. Electroplating Bath Solution Circulation
Electroplating relies on precise chemical delivery—chemical hose circulates plating baths. It maintains consistent flow to ensure uniform coating on workpieces. Reinforced chemical hose handles high pressure and temperature fluctuations in plating tanks. Food-grade or high-purity chemical hose prevents contamination, preserving plating quality.
3. Anodizing Process Fluid Management
Anodizing uses sulfuric acid or chromic acid—chemical hose transfers these electrolytes to anodizing cells. Heat-resistant chemical hose withstands the process’s 20–30℃ operating temperature. It also carries rinsing water to neutralize workpieces post-anodizing. Fluoropolymer chemical hose excels here, as it repels acid absorption and degradation.
4. Paint and Coating Material Delivery
Surface finishing requires paint, primers, or powder coating fluids—chemical hose transports these viscous materials. Flexible chemical hose bends easily around equipment, reaching spray guns or coating baths. It resists swelling from solvents in paints or lacquers. Nitrile or polyurethane chemical hose works best for oil-based coatings, ensuring smooth, clog-free flow.
5. Wastewater and Effluent Transfer
Post-treatment, chemical hose removes contaminated wastewater and sludge. Corrosion resistant chemical hose handles acidic/alkaline effluents without leaking. It connects treatment tanks to filtration or disposal systems. Heavy-duty chemical hose with reinforced layers withstands abrasive particles in sludge, extending service life.
6. Key Selection Tips for Surface Treatment Chemical Hose
Match chemical hose material to fluid type. Prioritize pressure ratings for high-flow processes. Ensure compatibility with temperature ranges. Choose certified chemical hose to meet industry safety standards.
