The production line consists of: feeding system, paste-making system, tinting system, discharging & filtrating system, filling system and control system; It can satisfy the production of various building paint such as exterior wall paint, interior wall paint, elastic paint, wall putty etc. Using hydraulic lifting high speed disperser and basket mill as pulping devices, the grinding products have the advantages of good fineness, high stability, small chromatism and less pollution. This production line is characterized in less investment, less area occupation, easier running and maintenance and higher investment return.
Materials | Characteristics | Capacity | Application |
Water-based paint | Viscosity ≤20,000 cps | 1,000T/year | Suitable for manufacturing of water-based paint, water dilutable coating, water dispersible paint(latex paint) and etc. |
Working principle
Generally speaking, water-based paint production process contains following steps: batching, dispersing, milling, tinting, filtering and filling.
Batching and conveying: liquid batching adopts pumps, flow meter; powder batching adopts weighing system and air conveying; additives batching adopts weighing method.
Dispersing: the first step to make paste. Powder material is equably dispersed into liquid by high-speed disperser which generates uniform white paste without aggregation.
Milling: second step of making paste. White paste is ground to required fineness by German-tech basket mill.
Tinting: emulsion, color paste and additive are added into paste and mixed by single shaft or multi-functional mixer in tinting kettle.
Filtering: impurities are removed with the help of bag type filter or self-cleaning filters.
Filling: filtered products are filled whose specification is normally 10-25kg. Semi-auto or automatic filling machine are optional.
System name | Equipment name | Specification |
Feeding system | Powder feed hopper, emulsion feed hopper, auxiliary storage tank | The material is SS304, internal and external mirror polishing |
Paste-making system | hydraulic lifting high speed disperser, basket mill, movable tank | The powder is quickly and evenly dispersed by the hydraulic lifting high speed disperser. Transfer the evenly mixed white paste to a basket mill and grind it to the desired fineness |
Tinting system | Emulsion barrel (weighbridge), pneumatic diaphragm pump, hydraulic lifting high speed disperser, movable tank | The auxiliaries and emulsions are weighed by the weighbridge, transported to the moving tank (prepared slurry) by the pneumatic diaphragm pump of caliber DN40, and evenly blended by the hydraulic lifting high-speed disperser |
Discharging & filtrating system | Movable tank, filter cart | Filter out impurities. The filter cart includes: stainless steel bag filter, pneumatic diaphragm pump, air source two coupling, single air control valve, which is installed on the trolley and can be moved at will |
Filling system | Semi-auto filling machine | Filling quantity 160-300 pails/hour, with lid clamping device (metal pail) and lid pressing device (plastic pail)
Filling range: 0.5-5L and 5-30L |
