1、 Overview of industrial pure water equipment for water-based coatings:
1. Water standard for industrial pure water equipment used in water-based coatings. Water based coatings refer to coatings that use water as a solvent or dispersant. Generally, tap water or well water cannot meet the production needs of water-based coatings. Poor water quality has a significant impact on product quality and performance. Therefore, it is necessary to treat the raw water to meet the standard of pure water before use, in order to improve product quality and performance. Therefore, industrial pure water equipment needs to use deionized water.

2、 Water quality standards for industrial pure water equipment used in water-based coatings:
Water Quality Requirements: Deionized Water Water Quality Standard: Conductivity<10 µ S/cm
Raw water requirements: municipal or deep well water
Process flow: Primary reverse osmosis
Equipment material: PVC pipe+fiberglass reinforced plastic
RO membrane selection: Dow RO membrane, Heideneng RO membrane, Dongli RO membrane, domestic Huitong RO membrane, etc

3、 Process flow of industrial pure water equipment for water-based coating production
Raw water tank - booster pump - quartz sand filter - activated carbon filter - water softener - primary RO reverse osmosis host - pure water tank - water point.

4、 Execution standards:
100% compliance with execution standards
JB/T 2932-1999 "Technical Conditions for Manufacturing Water Treatment Equipment"
GB/T19249-2003 "Reverse Osmosis Water Treatment Equipment"
GB5749-2006 "Sanitary Standards for Drinking Water"
GB8978-2002 "Pollutant Discharge Standards for Urban Sewage Treatment Plants"
