Avoid businesses selling substandard products that fail to meet fire protection requirements. (3) According to the author's understanding, currently, domestic enterprises produce fire-resistant coatings that meet level two standards, with prices at 8000 yuan/ton and above. If the selling price is below this, the quality is questionable. (4) On-site application of fire-resistant coatings should follow the instructions on the manufacturer's product packaging; generally, no water thinning is required. The coating should be applied in two or more coats, with a minimum of 500g/square meter. If the fire-resistant coating is water-thinned or not applied adequately, it will significantly affect its 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 expand greatly when exposed to intense heat from blowtorches, with the surface forming raised bumps without burning through within minutes. On the other hand, counterfeit fire-resistant coatings will barely foam and will have a lot of loose particles. The wooden base material will also quickly burn and break. (6) If possible.
You can also conduct an initial quality check of the product on-site: Cut 2 to 3 small samples from the already installed base material, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, and brush it according to the actual application. After it dries, inspect it with the flame of an alcohol lamp. The flame height should be around 40mm, and the application time is generally 20 minutes to check for foam formation. Normally, applying the coating in the specified amount (usually 500g/square meter) results in a foam layer thickness of 20mm or more for Class 1 fire-resistant coatings, and 10mm or more for Class 2 fire-resistant coatings. The foam layer should be 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 usual amount of fire-resistant coating is 350 to 500g/square meter, while the topcoat is typically 50g/square meter. Secondly, due to an unreasonable application plan, the fire-resistant coating on the steel structure is too thin.
The purpose of applying fire-resistant coatings to 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 thicknesses. It is essential to choose the appropriate coating thickness based on the building's fire resistance limit for effective fire protection. Thirdly, there may be surface imperfections in the fire-resistant coating of steel structures during construction, caused by two factors: improper surface preparation and uneven application during coating. Fourthly, selecting the wrong type of fire-resistant coating during application is critical. Different types of coatings have varying thickness requirements and fire resistance limits on steel structures. To ensure the fire resistance limit meets fire safety standards, it's 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 exposure to rain and direct sunlight. Performance indicators: Appearance, Bulk Density, Water Resistance, Oil Resistance, Compressive Strength, Drop Resistance, Fire Resistance - Complete, No Damage, 0.6×10^3 kg/m^3
≥3d no visible changes in packaging material, intact and undamaged; R≥0.05Mpa, when dropped from a height of 5m onto a concrete level surface, no damage to the packaging; fireproof sealing material with a fire resistance limit of ≥180min.
Fires caused by reasons such as cabinet rot, wiring aging, equipment short-circuiting, and improper operation of electrical equipment are the most common in enterprises. The main reason is that with the promotion of fire-resistant knowledge for steel structures, people have also begun to value the fire resistance of steel structures. The convenience and simplicity of using fire-resistant coatings for steel structures have made them widely used. However, as more people use them, some issues have been discovered. Due to a lack of understanding of fire-resistant coatings for steel structures, the purchased coatings may be (1) Verify if the product has a qualified inspection report issued by a fire inspection and quality supervision center, or you can 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 qualified inspection. (2) According to national standards, in addition to meeting fire resistance requirements, the combustion performance of fire-resistant coatings is divided into Grade 1 and Grade 2. Under specified test conditions, the burn resistance time of Grade 1 fire-resistant coatings is not less than 20 minutes, and the heat resistance time of Grade 2 fire-resistant coatings is not less than 10 minutes. Users should pay attention to differentiate when choosing.
Avoid enterprises from passing off inferior products as high-quality ones, which fail to achieve the fire protection effect. (3) According to my research, currently, fire-resistant coatings produced by domestic companies that meet the second-level fire-resistant standard are priced at over 8000 yuan per ton. If the selling price is below this, the quality is questionable. (4) On-site application of fire-resistant coatings should be guided by the manufacturer's product packaging instructions. Generally, no water thinning is required, and the coating should be applied in two or more coats, with a minimum of 500g per square meter. If the fire-resistant coating is water-thinned or applied insufficiently, it will significantly impact its fire-resistant properties. Fire departments should strengthen supervision of construction sites to prevent contractors from cutting corners. (5) Genuine fire-resistant coatings will foam and expand when exposed to intense flames like blowtorches, with the surface bulging without burning for several minutes. On the other hand, counterfeit fire-resistant coatings will not foam much and will show a lot of loose particles. The wood substrate will also burn and break down quickly. (6) If possible.
Upon site, a preliminary quality check of the product can be conducted: Cut 2 to 3 small samples from the already installed base material, or apply a small amount of sample onto 2 to 3 150mm x 150mm plywood panels, and paint as per the actual construction process. After drying, inspect using the flame of an alcohol lamp. The flame height should be around 40mm, and the duration of flame application is generally 20 minutes, to check for foam formation. Normally, when applied in the prescribed quantity (typically 500g per square meter), the foam layer of Class 1 fire-retardant coating should be 20mm or more in thickness, and for Class 2, 10mm or more. The foam layer should be uniform and dense. In actual use, to ensure the fire-retardant properties and other performance of the fire-retardant coating, a transparent topcoat is usually required. The amount of fire-retardant coating typically ranges from 350 to 500g per square meter, while the topcoat application is usually around 50g per square meter. Second, due to an不合理 construction plan, the fire-retardant coating on the painted steel structure is too thin.
The purpose of applying fire-retardant coatings on steel structures is to enhance their fire resistance limit, which is closely related to the coating thickness. Different thicknesses of the same fire-retardant coating will result in varying fire resistance limits. It is essential to choose the appropriate coating thickness based on the building's fire resistance limit for effective fire protection. Thirdly, there may be surface irregularities in the fire-retardant coating of steel structures during construction, caused by two factors: improper surface preparation and uneven application. Fourthly, selecting the wrong type of fire-retardant coating can be problematic. Different types of coatings have varying thickness requirements and fire resistance limits on steel structures. Applying different types of coatings to various parts of the steel structure ensures that the fire resistance limit meets fire safety standards. Choosing the wrong type can compromise fire safety even if the coating thickness is adequate. Fire-retardant coatings for steel structures can be categorized into indoor and outdoor types based on the construction environment.
Indoor steel structure fire-resistant coatings lack certain properties of outdoor steel structure fire-resistant coatings and cannot adapt to outdoor environments, thus they are not suitable for outdoor fire protection. In contrast, outdoor steel structure fire-resistant coatings can be used for indoor fire protection. Additionally, ultra-thin and thin-coated steel structure fire-resistant coatings, due to their better decorative properties, have a fire resistance limit of two hours or less. Therefore, they are generally used on steel structures that require decorative effects within two hours. Thicker-coated steel structure fire-resistant coatings, with their poor decorative qualities and fire resistance limit exceeding two hours, are used on steel structures where no decorative effect is required for more than two hours. Fifthly, the construction team chosen for the steel structure fire-resistant coating is不合格. The quality of the construction of steel structure fire-resistant coatings directly affects the fire-resistant properties and performance of the coating. According to national regulations, the application of steel structure fire-resistant coatings should be carried out by trained and qualified personnel. Sixthly, the decorative coating and welding, as well as dismantling tools, have damaged the fire-resistant coating layer. There has been no timely repair. To ensure the fire resistance of the steel structure fire-resistant 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 quickly and dense smoke filling the area. Thankfully, there were no casualties due to timely rescue efforts. It is widely known that fires are becoming more frequent. To prevent fires, the Fire Department has stipulated that fire-resistant coatings must be applied during the construction of factories. However, can fire-resistant coatings really prevent fires? Fire-resistant coatings are a type of flame-retardant paint made from a variety of materials, including film-forming agents, flame retardants, and foaming agents. Common types include decorative fire-resistant coatings, wood fire-resistant coatings, and steel structure fire-resistant coatings, with a wide range of applications. The fire-resistant mechanism of fire-resistant coatings lies in their inherent flame retardancy or non-flammability, which prevents the protected material from coming into direct contact with air, delaying ignition and reducing the rate of combustion. In addition to their flame retardancy or non-flammability, fire-resistant coatings also have a low thermal conductivity, which can delay the transfer of flame temperature to the protected material. When heated, fire-resistant coatings decompose to release non-flammable inert gases, diluting the flammable gases released by the protected material upon heating.
Make it less flammable or slow down the burning rate. Nitrogen-rich fire-retardant coatings decompose upon heating to release groups such as NO and NH3, which react with organic free radicals, breaking the chain reaction and reducing temperature. Intumescent fire-retardant coatings expand and foam upon heating, 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 burning or from strength degradation due to temperature rise. The main characteristics of fire-retardant coatings are achieved through micronization technology and formula optimization, which result in an excellent adhesion and strength of the intumescent carbonization layer, maintaining good adhesion even under strong airflow impacts, thereby completely resolving the issue of carbonization layer delamination (double skin phenomenon). Long-lasting Corrosion Protection: By modifying synthetic resins and micronizing raw materials, the poor corrosion resistance caused by physical defects in raw materials is effectively addressed, significantly enhancing the product's corrosion resistance and durability. Types of Fire-Retardant Coatings: This refers to the resin in the fire-retardant paint.
To ensure the quality of fire-resistant coating application on steel structures, a key highlight is selecting qualified fire-resistant coatings 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 team must have fire-resistant coating application qualifications, which must be recognized by the fire supervision department. Construction personnel should be trained and proficient in the application process. Second, inspect the selected construction personnel for fire-resistant coating application, inquire about relevant information such as application precautions and steps, to prevent unqualified personnel. Third, have the fire-resistant coating construction personnel perform a trial application, observe the results. Unqualified applications should be replaced promptly. Fourth, to prevent issues with construction personnel, provide them with basic training to enhance their knowledge, thereby reducing the likelihood of discovering unqualified work.
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 Fire Protection Material Co., Ltd. will 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 for production staff specializing in steel structural fire-resistant coatings. Skilled workers not only operate quickly but also boost production capacity. Therefore, strengthening the training of these production staff is also a way to reduce production costs. Secondly, locate the production facility close to the raw material market. Establishing a plant near the raw material market can increase production speed and reduce transportation costs, thereby lowering the production costs of steel structural fire-resistant coatings. Thirdly, choose cost-effective raw material suppliers. The price of raw materials plays a significant role in determining the cost of steel structural fire-resistant coatings.
Interior steel structure fire-retardant coatings do not possess the same properties as exterior steel structure fire-retardant coatings and cannot withstand outdoor environments, thus they are not suitable for outdoor fire protection. In contrast, exterior steel structure fire-retardant coatings can be used for interior fire protection. Additionally, ultra-thin and thin-coating steel structure fire-retardant coatings are favored for their decorative appeal and have a fire resistance limit of two hours or less. Therefore, they are commonly used on steel structures requiring decorative effects within a two-hour limit. Thicker-coating steel structure fire-retardant coatings, with poor decorative qualities but a fire resistance limit exceeding two hours, are used on structures where no decorative effect is required for over two hours. Fifthly, the chosen steel structure fire-retardant coating construction team is不合格. The quality of steel structure fire-retardant coating construction directly affects the fire protection and performance of the coating. According to national regulations, steel structure fire-retardant coating construction should be carried out by trained personnel. Sixthly, the coating was damaged during decorative work, welding, and dismantling of tools, and was not promptly repaired. To ensure the fire resistance limit of the steel structure fire-retardant coating, repairs should be made promptly when the coating is damaged.
