Paint Production Line Introduction | JCT Machinery

May 29, 2025

1. Ingredient Differences

Oil-based Paint: Uses organic solvents (such as toluene, xylene, banana water) as dilution and carrier media.

Water-based Paint: Uses water as the main dilution medium, supplemented by emulsions, additives, etc.


2. Environmental Protection and VOC Emissions

Oil-based Paint: High VOC (volatile organic compound) content, strong odor, impact on the environment and human body, strict emission requirements.

Water-based Paint: Low VOC, good environmental protection, more in line with the environmental regulations of the European Union, the United States and other countries.


3. Equipment Configuration of Paint Production Line

4. Cost and Performance

Oil-based paint:

    • The coating is full, dries slowly, has strong adhesion, and is suitable for outdoor or industrial use.

    • The cost is high, and fire prevention should be paid attention to during construction.

Water-based paint:

    • Dries quickly, is safer to operate, and is suitale for environmentally sensitive fields such as home decoration, furniture, and children's toys.

    • Some properties (such as wear resistance and corrosion resistance) are slightly inferior to high-end oil-based paints, but are improving rapidly.


5. Market Trends

Globally, water-based paint is gradually replacing oil-based paint.

In developed countries and environmentally controlled areas (such as the European Union and North America), water-based paint accounts for more than 70%.



The role of high speed disperser in paint production line
1. Premixing of pigments and resins
2. Uniform dispersion of additives
3. Depolymerization and dispersion of fillers
4. Forming a primary slurry system

Especially in the production of tinting paints, primers, topcoats, latex paints, industrial paints, wood paints, etc., the efficiency and uniformiry of high speed disperser directly affect the gloss, hiding power and stability of the final product.

Structural features of high speed disperser
1. Dispersion disc: Gear-type serrated dispersion disc, strong shear force, wear-resistant.
2. Lifting structure: Hydraulic or pneumatic lifting, easy to clean and replace the tank.
3. Variable frequency speed regulation: The speed can be adjusted according to the characteristics of the material (commonly 0~1440rpm).
4. Cylinder structure: Can be equipped with single-layer or jacket mixing cylinder (with cooling function).
5. Material: SS304/316 is often used, corrosion-resistant.
