Comprehensive Guide to Coatings: Classification, Production, and Equipment

I. Introduction to Coatings

Coatings are liquid or solid materials that form a thin film on surfaces under specific conditions, providing protection, decoration, and other special functions. These functions can include insulation, rust prevention, mildew resistance, and heat resistance, making coatings an essential component in multiple industries, from construction to automotive and aerospace.

Coatings Filling Machines: Production and Equipment KEYWORD List

1. Primary Keywords (Short-Tail – High Volume/High Competition)

These are the core terms that should form the basis of your H1 and H2 tags.

2. Commercial & Transactional Keywords (High Intent – “Buy Now”)

These are used by prospects ready to purchase or request a quote. Use these in your Call-to-Action (CTA) sections and product pages.

3. Long-Tail Keywords (Specific Needs – Lower Competition)

These phrases address specific operational needs or container formats, capturing niche, high-quality traffic.

4. Informational Keywords (Educational Content – “How-To” & “Guide”)

These are excellent for blog content, comprehensive guides, and H3 headers, establishing authority and capturing early-stage buyers.

III. Coating Production Process and Equipment

1. Water-Based Paint Production (Latex Paint)

GZLON Group offers a complete water-based paint production line with eight integrated systems:

1. Powder and Liquid Feeding System – Including pneumatic conveying, screw conveying, and liquid conveying systems.

2. Pulping System – Ensures uniform raw material consistency.

3. Paint Mixing, Discharging, and Filtration System – High-efficiency mixing and filtration for consistent quality.

4. Filling System – Semi-automatic or fully automatic paint filling lines, including explosion-proof options.

5. Cooling System – Maintains optimal paint temperature during processing.

6. Piping System – Efficient material transfer between processes.

7. Electrical Control System – PLC and automation controls for smooth operation.

8. Operation Platform – Ergonomic platform for monitoring and controlling the production line.

GLZON fully automatic paint production lines are highly intelligent and efficient, suitable for large-scale production with annual capacities ranging from 1,000 to 100,000 tons. The equipment can independently complete vacuum feeding, dispersion, grinding, refining, cooling, mixing, filtration, and semi-automatic filling, with high degrees of automation.

2. Main Equipment

a) Powder and Liquid Feeding System

• Efficient pneumatic, screw, and liquid conveying systems for raw material delivery.

b) Paint Disperser

• Performs pre-dispersion, stirring, high-speed dispersion, mixing, and color matching.

• Adaptable to medium and high viscosity and thixotropic materials.

• Ideal for batch production with fast and convenient operation.

c) Basket Grinder

• Wet grinding equipment for high-fineness products such as paints, inks, pigments, color pastes, cosmetics, pesticides, and pharmaceuticals.

• Combines dispersion and sand grinding in one step, improving efficiency and reducing waste.

d) Paint Mixer

• Cylinder or trough with rotating blades to mix multiple raw materials, widely used for paints, inks, pigments, and adhesives.

e) Paint Mixing Kettle

• Agitators can be paddle, frame, or anchor types.

• Operates at low speed, suitable for homogenizing and blending.

f) Paint Filling Machines

• Small category equipment for semi-automatic or fully automatic filling lines.

• Can be explosion-proof or standard, depending on material properties.

3. Single-Machine Process Flow for Small-Batch Production

Traditional equipment usually includes:

• Disperser → Horizontal Sand Mill → Mixer

• Multiple cycles of grinding may be needed to achieve required fineness.

• Low investment and suitable for small-batch production.
