(Avoid businesses from passing off inferior products as high-quality ones, failing to meet fire protection standards.)(3) According to the author's research, currently, domestic companies produce fire-retardant coatings that meet Grade II standards, with prices at 8,000 yuan/ton and above. If the selling price is below this, the quality is questionable.(4) The on-site application of fire-retardant coatings should be based on the product's outer packaging instructions from the manufacturer, generally requiring no water dilution. It should be applied in two or more coats, with a minimum of 500g/m². Inadequate dilution or application of fire-retardant coatings will significantly impact their fire-retardant properties. Fire departments should strengthen supervision at construction sites to prevent contractors from cutting corners.(5) Genuine fire-retardant coatings will foam and expand upon being exposed to intense heat from torches, etc., with surface bumps that do not burn for several minutes. On the other hand, counterfeit fire-retardant coatings barely foam and will shed a lot of debris. The wooden substrate will also quickly catch fire and deteriorate.(6) If possible.
Also, a preliminary quality check of the product can be conducted on-site: Cut 2 to 3 small samples from the pre-installed substrate, or apply a small amount of the sample to 2 to 3 150mm x 150mm plywood sheets, and brush it according to the actual application process. After drying, inspect with the flame of an alcohol lamp. The flame height should be around 40mm, and the flame should be applied for approximately 20 minutes to check for bubbling of the coating. Normally, when applied at the recommended rate (usually 500g/square meter), the foam layer thickness of a Class 1 fire-resistant coating should be over 20mm, and for a Class 2 fire-resistant coating, over 10mm, with the foam layer being even and dense. (7) In actual use, to ensure the fire-resistant properties and other performance of the fire-resistant coating, it is generally necessary to use a transparent topcoat. The application rate of the fire-resistant coating is typically 350 to 500g/square meter, while the topcoat is usually applied at a rate of 50g/square meter. Secondly, due to an unreasonable construction plan, the fire-resistant coating on the painted steel structure is too thin.
The purpose of applying fire-resistant coatings on steel structures is to enhance their fire resistance limit, which is closely related to the coating thickness. The fire resistance limit of the same type of fire-resistant coating varies with different coating thicknesses. It is essential to choose the appropriate coating thickness based on the building's fire resistance limit to ensure effective fire protection. Thirdly, the surface of the fire-resistant coating on steel structures may have issues, caused by two factors: improper surface preparation and uneven application during coating. Fourthly, selecting the wrong type of fire-resistant coating can be problematic. Different types of coatings have varying thickness requirements and fire resistance limits on steel structures. To meet fire safety requirements, it is crucial to apply different types of fire-resistant coatings to different parts of the steel structure. Choosing the wrong type can compromise fire safety even if the coating thickness is adequate. Fire-resistant coatings for steel structures can be categorized into indoor and outdoor types, and during transportation, they should be handled as ordinary solid substances to prevent rain and direct sunlight exposure. Performance indicators: Appearance, Bulk Density, Water Resistance, Oil Resistance, Compressive Strength, Drop Resistance, Fire Resistance - Coating should be intact with no damage, 0.6×10^3 kg/m^3.
≥3 days no visible change in inner material, complete package with no damage; R≥0.05 Mpa, when dropped from 5 meters high onto a concrete flat surface, the package shows no damage; first-grade fireproof sealing material with fire resistance limit ≥180min.
Fire incidents in enterprises are most commonly caused by reasons such as the rotting of distribution cabinets, aging of wiring, equipment short circuits, and improper operation of electrical equipment. The main reason is that with the promotion of fire prevention knowledge for steel structures, people have also started to value the fire resistance of steel structures. The use of fire-resistant coatings for steel structures is convenient and simple, and has been widely adopted. However, as more people use them, issues have been identified. Due to a lack of understanding of fire-resistant coatings for steel structures, there is a possibility that the purchased coatings may be: (1) Verify if the product has a qualified inspection report issued by the Fire Prevention Quality Inspection Center, and also check online. Currently, fire-resistant coatings are subject to the type-approval system for fire products, and fire-resistant coatings sold on the market should have a national type-approval certificate for fire products and a type-approval report of conformity. (2) According to national standards, in addition to meeting fire resistance requirements, the combustion performance of fire-resistant coatings is classified into Level 1 and Level 2. Under specified test conditions, the burn time of Level 1 fire-resistant coatings should not be less than 20 minutes, and the heat resistance time of Level 2 fire-resistant coatings should not be less than 10 minutes. Users should pay attention to make the distinction when choosing.
Avoid businesses substituting inferior products for high-quality ones, failing to meet fire protection standards. (3) According to the author's research, currently, domestic companies producing fire-resistant coatings with a grade of level two cost over 8000 yuan per ton. If the selling price is lower than this, the quality is questionable. (4) On-site application of fire-resistant coatings should follow the manufacturer's instructions on the product's outer packaging; generally, no water thinning is required. It should be applied in two or more coats, with a minimum of 500g per square meter. Insufficient water thinning or application can greatly affect the fire-resistant properties. Fire departments should strengthen supervision at construction sites to prevent contractors from cutting corners. (5) Genuine fire-resistant coatings will foam and swell significantly when exposed to intense heat from blowtorches, with the surface forming raised bubbles without burning for several minutes. Counterfeit fire-resistant coatings, on the other hand, will barely foam and may shed large amounts of particles, and the wood substrate will quickly burn and break. (6) If possible.
Also, a preliminary quality check of the product can be conducted on-site: Cut 2 to 3 small samples from the already installed base material, or apply a small amount of the sample onto 2 to 3 150mm x 150mm plywood panels, and brush it on as per the actual application process. After it dries, inspect it with the flame of an alcohol lamp. The flame height should be around 40mm, and the flame should be applied for about 20 minutes to check the foaming of the coating. Under normal circumstances, applying the coating as per the specified quantity (usually 500g/square meter) results in a foam layer thickness of over 20mm for Class 1 fire-resistant coatings, and over 10mm for Class 2 fire-resistant coatings, with the foam layer being even and dense. (7) In actual use, to ensure the fire-resistant properties and other performance characteristics of the fire-resistant coating, it is generally necessary to apply a transparent topcoat. The usual application rate for the fire-resistant coating is 350 to 500g/square meter, while the topcoat is typically applied at a rate of 50g/square meter. Secondly, due to an unreasonable construction plan, the fire-resistant coating on the steel structure is excessively thin.
The purpose of applying fire-resistant coatings to steel structures is to enhance their fire resistance. The fire resistance performance of steel structures is closely related to the thickness of the applied coating. Different thicknesses of the same fire-resistant coating lead to varying levels of fire resistance. It is essential to choose the appropriate coating thickness based on the building's fire resistance requirements for effective fire protection. Thirdly, there may be irregularities on the surface of the fire-resistant coating during application, caused by two factors: improper surface preparation and uneven application. Fourthly, selecting the wrong type of fire-resistant coating can be problematic. Different types of coatings have varying thickness requirements and fire resistance levels on steel structures. Appropriate coating types must be applied to different parts of the steel structure to ensure that the fire resistance meets safety standards. Choosing the wrong type can compromise fire safety, even if the coating thickness is correct. Fire-resistant coatings for steel structures can be categorized into indoor and outdoor types based on the application environment.
Interior steel structural fire-retardant coatings lack some of the properties of exterior steel structural fire-retardant coatings, cannot adapt to outdoor environments, and therefore are not suitable for outdoor fire protection. In contrast, exterior steel structural fire-retardant coatings can be used for interior fire protection. Additionally, ultra-thin and thin-coating steel structural fire-retardant coatings, due to their better decorative properties, have a fire resistance limit of two hours or less. They are generally used on steel structures requiring decorative effects for two hours or less. Thicker-coating steel structural fire-retardant coatings, with poorer decorative properties, have a fire resistance limit of more than two hours and are used on structures where decorative effects are not required for more than two hours. Fifth, the construction team selected for the steel structural fire-retardant coating is不合格. The quality of the steel structural fire-retardant coating's construction directly affects its fire protection and performance. According to national regulations, the construction of steel structural fire-retardant coatings should be carried out by trained personnel. Sixth, the decorative coating and welding, as well as dismantling tools, have damaged the fire-retardant coating. There has been no timely repair. To ensure the fire resistance limit of the steel structural fire-retardant coating, repairs should be made promptly when the coating is damaged.
Recently, a polystyrene factory on Dalun Road in Dacun Township, Changhua County, caught fire, with the flames spreading rapidly and thick smoke filling the air. Thankfully, no injuries were reported due to timely rescue efforts. It is widely known that fires are occurring more frequently. To prevent such incidents, the Fire Department has stipulated that fire-retardant coatings must be applied during factory construction. However, does fire-retardant coating actually prevent fires? Fire-retardant coatings are a type of flame-retardant paint made from various materials such as film-forming agents, flame retardants, and foaming agents. Common types include decorative fire-retardant coatings, wood fire-retardant coatings, and steel structure fire-retardant coatings, with a wide range of applications. The fire-retardant mechanism of fire-retardant coatings lies in their inherent flame resistance or non-flammability, which prevents the protected material from coming into direct contact with air, delaying ignition and slowing the rate of combustion. Besides being flame-resistant or non-flammable, fire-retardant coatings also have a low thermal conductivity, which can delay the transfer of flame temperature to the protected material. When heated, fire-retardant coatings release non-flammable inert gases, diluting the flammable gases emitted during the heating decomposition of the protected object.
Reduce flammability or slow down the combustion rate. Nitrogen-rich fire-retardant coatings decompose upon heating to release groups like NO and NH3, which then combine with organic free radicals, interrupting the chain reaction and lowering temperatures. Expanding fire-retardant coatings heat up and foam, forming a carbon foam insulating layer that seals the protected object, delaying the transfer of heat to the base material, and preventing the object from catching fire or experiencing strength degradation due to temperature rise. The main characteristics of fire-retardant coatings are achieved through micronization technology and formulation optimization, resulting in an excellent adhesion and strength of the expanding char layer, even under strong airflow impact, thereby completely resolving the issue of char layer delamination (double skin phenomenon). Long-lasting Corrosion Protection: By modifying synthetic resins and micronizing raw materials, the problem of poor corrosion resistance caused by physical defects in raw materials is effectively addressed, significantly enhancing the corrosion and durability performance of the product. Types of fire-retardant coatings: This refers to the resin in the fire-retardant paint.
To ensure the qualification of fire-resistant coating application on steel structures, a key highlight is selecting qualified fire-resistant coatings for steel structures and a competent construction team. Below, we introduce how to choose a fire-resistant coating construction team for steel structures. Check the qualifications of the construction team. The focus is on verifying that the team has the necessary fire-resistant coating application qualifications, which must be recognized by the fire supervision department. Construction personnel should be trained and knowledgeable about the construction process. Second, inspect the selected construction personnel for steel structure fire-resistant coatings, inquire about relevant information on fire-resistant coating application. For example: precautions for fire-resistant coating application, steps for fire-resistant coating application, etc., to prevent the presence of unqualified personnel. Third, have the steel structure fire-resistant coating personnel perform a trial application, observe the results. Unqualified personnel should be replaced promptly. Fourth, to prevent issues with construction personnel, provide them with a basic training session to enhance their knowledge. This reduces the likelihood of discovering unqualified situations.
Many fire-resistant coating companies aim to reduce the production costs of fire-resistant coatings while maintaining quality unchanged. To be honest, it's challenging, but today, Beijing Xingkun Fireproof Material Co., Ltd. is here to show you how to achieve this goal. More importantly, it's crucial to ensure that the quality and effectiveness of the fire-resistant coatings are not compromised. Firstly, enhance the training of production staff for steel structure fire-resistant coatings. Skilled workers not only operate quickly but also have high production capacity. Therefore, strengthening the training of production staff for steel structure fire-resistant coatings is also a way to reduce production costs. Secondly, choose a location close to the raw material market for factory production of steel structure fire-resistant coatings. Establishing factories closer to the raw material market can increase production speed, reduce transportation costs, and ultimately lower the production costs of steel structure fire-resistant coatings. Thirdly, select affordable raw material manufacturers. The cost of steel structure fire-resistant coatings is largely determined by the price of raw materials.
Indoor steel structural fire-resistant coatings lack some properties of outdoor steel structural fire-resistant coatings, making them unsuitable for outdoor environments and therefore not suitable for outdoor fire protection. In contrast, outdoor steel structural fire-resistant coatings can be used for indoor fire protection. Moreover, ultra-thin and thin-film steel structural fire-resistant coatings are often used on decorative steel structures due to their better aesthetics, as their fire resistance rating is within two hours. Thick-film steel structural fire-resistant coatings, with their poor decorative qualities and fire resistance ratings exceeding two hours, are used on structures that do not require decorative effects for more than two hours. Fifthly, the construction team chosen for the application of the steel structural fire-resistant coatings is不合格. The quality of the construction work directly affects the fire-resistant coating's performance. According to national regulations, the application of steel structural fire-resistant coatings should be carried out by trained personnel. Sixthly, the protective coating was damaged during decorative work, welding, and dismantling, but was not repaired promptly. To ensure the fire resistance of the steel structural fire-resistant coatings, the coating should be repaired promptly when damaged.
