1.The definition and classification of fireproofing paint for steel structures
Fireproofing paint is a commonly used material for economic and effective fire prevention. The composition of fireproof paint includes flame retardant compounds such as rice husk, acrylic, epoxy, and other special chemical additives and chemicals. After painting the materials that need to be fireproof, which are iron, steel, and fireproof paint, they will form a protective layer that helps the steel structure avoid harmful effects when exposed to fire for a long time.
Fireproofing paint for steel structures includes two types:
Oil-based: This is a popular paint because it works well for indoor and outdoor use. Oil-based paints can adapt to many weather environments, limit harmful agents, and have high water resistance.
Water-based: This is a safe, environmentally friendly paint that is easy to clean after use. However, water-based fireproof paint can absorb moisture, making it easy to have a thin finish.
2. Benefits of using fireproofing paint for steel structures at construction sites
The outstanding feature of fireproofing paint for steel structures is maximum heat resistance up to 1000oC. The paint's fire resistance can last up to 3 hours or more (depending on the type of paint). The high heat resistance of fire retardant paint helps to keep the steel structures unaffected, limiting casualties and damage. This property also helps slow the spread of fire and prolong the time it takes to put out the fire.
In addition to ensuring safety for people and property, fireproof paint also limits the amount of toxic gas released from the fire. This makes the firefighting work more convenient and less dangerous. And yet, this passive fire protection material is easy to apply and does not take much time to construct.
Thanks to the composition of epoxy resin, flame retardant Poly Phosphor, organic solvents, and insulation foam, fireproofing paint can slow down the heat exposure of steel structures in the event of a fire incident. Therefore, this paint is widely applied in many industries such as petroleum, petrochemical, power plant, and construction. In addition to steel structures, fireproof paint can be applied flexibly on other materials such as concrete, wood, etc.
In addition to steel structures, fire retardant paint can be used for many other materials such as concrete, wood, etc. No matter what surface is covered, fireproofing paint can still perform well the function of fire and surface
e Retardant Coating For Steel Structure
The intumescent fire retardant coating for steel structure has thin coating thickness, strong adhesion, good fire resistance and excellent decorative effect. When the fire retardant coating meets fire, it can expand and foam rapidly to form a dense and uniform fire insulation layer, so as to protect the fire protection of steel. At the same time, the coating has excellent physical and chemical properties, fast drying, moisture resistance, acid and alkali resistance. The product is generally white, and can also be mixed into various colors according to user requirements.
materials. Typically applied to surfaces such as wood, metal, concrete, etc., this coating enhances the resistance of these
materials during a fire.
2. Temperature Control: Fire-resistant coatings can form a protective layer at high temperatures, slowing down the rate at which materials heat up and helping to maintain the stability of the building structure.
3. Smoke Resistance: Some fire-resistant coatings are designed to resist smoke, reducing the production of toxic fumes during a fire and improving the safety of evacuation routes.
4. Ease of Application: Most fire-resistant coatings are easy to apply, using methods such as brushing, spraying, etc., making them suitable for a variety of surfaces.
5. Durability: Fire-resistant coatings typically exhibit good durability, maintaining their fire-resistant properties over an extended period and reducing maintenance requirements.
6. Environmental Friendliness: Advanced formulations of fire-resistant coatings use eco-friendly materials, meeting environmental standards.
