Industrial Pure Water Equipment for Waterborne Coatings
Ⅰ. Why does waterborne coatings production need specialized pure water equipment?
In the manufacturing process of water-based coatings, water quality directly affects product performance and stability. Ordinary tap water or well water contains a large number of impurities, minerals and ions, which can lead to the following problems in coatings:
• Uneven color
• Poor dispersion
• Reduced stability
• Coating surface defects
• Shortened shelf life
Professional industrial water purification equipment can remove more than 99% of the impurities in the water and provide high purity deionized water with conductivity <10µS/cm to ensure the stable and reliable quality of water-based coatings.
Ⅱ. Core parameters of water-based paint water purification system
1. Strict water quality standard
• Conductivity: <10µS/cm (better than the industry standard)
• PH value: 6.5-7.5 (neutral range)
• Microorganisms: <100CFU/ml
• Particulate matter: <1µm
2. Wide adaptability of raw water
• Municipal tap water
• Deep well water
• Surface water (pre-treatment required)
Ⅲ. Water-based paint water purification equipment process flow analysis
1. Raw water pretreatment system
• Raw water tank: buffer raw water pressure fluctuations
• Quartz sand filter: removing suspended solids and sediment.
• Activated carbon filter: adsorption of residual chlorine, organic matter
• Water softener: removing calcium and magnesium ions, preventing scaling.
2. Core purification unit
• First-class RO reverse osmosis host: remove more than 98% of dissolved salts and organic matter
• High pressure pump: provide stable working pressure (0.8-1.2MPa)
3. Post-treatment system
• Pure water tank: food-grade PE material, with air filter
• UV sterilizer (optional): to ensure that microorganisms meet the standard
• Precision filter (optional): 0.2μm terminal filtration
Ⅳ. Equipment Core Advantages and Selection Guide
1. Key Component Configuration
• RO Membrane Selection: U.S. Dow/Japan Toray (high desalination rate)/domestic Huitong (cost-effective)
• Piping system: UPVC/304 stainless steel (food grade)
• Control system: automatic PLC control (optional manual / semi-automatic)
2. Equipment Technical Parameters
| Parameter | Specification |
|---|---|
