The working principle of Wanda vermiculite in the fire-resistant and fire-proof industry:

Wanda vermiculite can produce refractory bricks, refractory boards, refractory mortar, fire retardant coatings, etc.

The fire retardant coating vermiculite is coated on the surface of the substrate. In addition to its flame retardant effect, it also has anti-rust, waterproof, anti-corrosion, wear resistance, heat resistance, as well as coating toughness, coloring, adhesion, easy drying and certain properties. gloss and other properties.
The tunnel fire retardant coating was completed by our unit with the assistance and support of many domestic fire protection research institutes and some large domestic fire retardant material manufacturers. It integrates the different characteristics of various fire-proof and flame-retardant materials and is developed based on the performance characteristics of concrete structures.
Performance characteristics include: high bonding strength, good water resistance, thin coating, high fire resistance time limit, good physical and chemical properties, etc. The product quality indicators have passed the quality inspection of the National Fireproof Building Materials Quality Supervision and Inspection Center and are suitable for fire protection of concrete structures such as highways, railways, subways, street tunnels and underground projects.
1. High fire resistance limit
Generally, tunnel fire retardant coatings heat up according to the HC curve. When the coating thickness is 20mm±2mm, the fire resistance can reach 2h. The fire retardant coating developed by our company heats up according to the HC curve. When the coating thickness is 15mm, the fire resistance limit can reach 2h.
2. High adhesion
Tunnel fire-retardant coatings must be able to withstand the strong wind and vibration environment in which the tunnel is located, so the tunnel fire-retardant coatings must have good adhesion.
3. Pay attention to environmental protection
When a fire occurs, tunnel fire retardant coatings should not produce toxic gases to facilitate fire fighting. Our unit pays attention to the research on the smoke-generating toxicity of coatings, and the fire-retardant coatings developed do not produce smoke-toxicity.
4. Good water resistance and chemical resistance
5. Convenient construction and mature technology
The tunnel fire-retardant coatings produced by many domestic and foreign manufacturers are not sticky during construction, but the tunnel fire-retardant coatings produced by our company are sticky fire-retardant coatings. During construction, the coatings are easy to adhere to the tunnel walls and vaults, and bond firmly with them.
