(1) Prevent businesses from selling substandard products that fail to meet fire protection requirements. (3) According to the author's understanding, currently, fire-resistant coatings produced by domestic enterprises that meet the second-level fire-resistant standard are priced at over 8,000 yuan per ton. If the selling price is below this, the quality is questionable. (4) The on-site application of fire-resistant coatings should follow the manufacturer's instructions on the product's outer packaging; generally, no water dilution is required. The coating should be applied in two or more coats, with a minimum of 500 grams per square meter. If the fire-resistant coating is diluted with water or applied insufficiently, 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 developing raised bubbles that will not burn within minutes. On the other hand, counterfeit fire-resistant coatings will not foam much and will shed large amounts of debris, with the wood substrate quickly catching fire and deteriorating. (6) If possible.
You can also conduct an initial quality check of the product on-site: Cut 2 to 3 small samples from the pre-applied substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood panels, and paint as per the actual application process. After drying, inspect using 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 foam formation. Normally, when applying the coating at the recommended rate (usually 500g/square meter), the foam layer of first-class fire-resistant coating should be 20mm or more, and the foam layer of second-class fire-resistant coating should be 10mm or more, 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 usual application rate for fire-resistant coating is 350 to 500g/square meter, while the topcoat application rate is typically 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-retardant coatings on steel structures is to enhance their fire resistance. The performance indicators of fire resistance in steel structures are closely related to the coating thickness. Different thicknesses of the same fire-retardant coating result in varying fire resistance limits. It is essential to choose the appropriate coating thickness for fire protection based on the building's fire resistance requirements. Thirdly, there may be irregularities on the surface of the fire-retardant coating during application, 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, and using the incorrect type can compromise fire safety. To ensure the fire resistance meets requirements, different types of fire-retardant coatings should be applied to different parts of the steel structure. Incorrect type selection, even if the coating thickness is correct, does not guarantee fire safety. Fire-retardant coatings for steel structures can be categorized into indoor and outdoor types, and should be transported as ordinary solid substances to prevent rain and excessive sun exposure. 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.
≥3 days, no visible changes in packaging material, intact and undamaged; R≥0.05 Mpa, when dropped from a height of 5 meters onto a concrete flat surface, no damage to the package; fire-resistant material for first-grade fireproofing with a fire resistance limit of ≥180 minutes.
Fires caused by reasons such as the rotting of distribution cabinets, aging of wiring, equipment short circuits, and improper operation of electrical equipment are the most common in enterprises. The main reason is that with the promotion of fire prevention knowledge for steel structures, people have also begun to value the fire prevention 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 it, some issues have been discovered. Due to the lack of understanding of fire-resistant coatings for steel structures, the purchased coatings may be: (1) Check if the product has a qualified inspection report issued by the Fire Control Quality Inspection Center, and can also be searched online. Currently, fire-resistant coatings are subject to the type recognition system for fire products, and the fire-resistant coatings sold on the market should have the national type recognition certificate for fire products and a type inspection report of qualified. (2) According to national standards, in addition to meeting the fire resistance requirements, the combustion properties of fire-resistant coatings are divided into level one and level two. Under the specified test conditions, the combustion resistance time of level one fire-resistant coatings should not be less than 20 minutes, and the heat resistance time of level two fire-resistant coatings should not be less than 10 minutes. Users should pay attention to differentiate when selecting.
(1) Prevent companies from passing off inferior products as high-quality ones, failing to meet fire protection standards. (3) According to the author's understanding, currently, domestic companies producing fire-resistant coatings that meet level two standards 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 follow the manufacturer's instructions on the product's outer packaging. Generally, no water dilution is required. The application should be done in two or more coats, with a minimum of 500 grams per square meter. Inadequate dilution or insufficient application of fire-resistant coatings can significantly affect their 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 significantly when exposed to intense heat from blowtorches, with the surface developing bumps without burning within minutes. On the other hand, counterfeit fire-resistant coatings barely foam and will shed large amounts of debris, with the wood substrate quickly catching fire and deteriorating. (6) If possible.
A preliminary quality check of the product can be conducted on-site: Cut 2 to 3 small samples from the pre-installed base material, or apply a small amount of the sample onto 2 to 3 150mm x 150mm plywood panels, and paint as per the actual application. 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 in the coating. Under normal conditions, applying the coating as per the recommended quantity (usually 500g/square meter) should result in a foam layer thickness of over 20mm for first-grade fire-resistant coating and over 10mm for second-grade fire-resistant coating, 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 use a transparent topcoat. The amount of fire-resistant coating typically used is 350 to 500g/square meter, while the topcoat usually requires 50g/square meter. Secondly, due to an unreasonably designed application method, the fire-resistant coating on the painted 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. The thickness of the fire-resistant coating should be selected rationally based on the building's fire resistance limit to ensure adequate fire protection. Thirdly, during construction, the surface of the fire-resistant coating on steel structures may have issues, primarily due to improper surface preparation and uneven application during coating. Fourthly, choosing the wrong type of fire-resistant coating during application is incorrect. Different types of fire-resistant coatings have varying thicknesses and fire resistance limits when applied to steel structures. To ensure the fire resistance limit of steel structures meets fire safety requirements, different types of fire-resistant coatings should be applied to different parts of the structures. If the wrong type is chosen, even if the coating thickness is adequate, fire safety cannot be guaranteed. Fire-resistant coatings for steel structures can be categorized into indoor and outdoor types based on the construction environment.
Interior steel structure fire-resistant coatings do not possess the same properties as exterior steel structure fire-resistant coatings and cannot withstand outdoor environments, thus they are not suitable for outdoor fire protection. In contrast, exterior steel structure fire-resistant coatings can be used for indoor fire protection. Additionally, ultra-thin and thin-film 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 requiring decorative effects within two hours. On the other hand, thick-film steel structure fire-resistant coatings, with poor decorative properties, have a fire resistance limit exceeding two hours and are used on steel structures that do not require decorative effects for durations over two hours. Fifthly, the construction team chosen for the steel structure fire-resistant coating is不合格. The quality of the construction 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 personnel. Sixthly, the coating was damaged during decoration, welding, and dismantling of construction tools, and was not repaired promptly. To ensure the fire resistance limit of the steel structure fire-resistant coating, any damage to the coating should be repaired immediately.
Recently, a polystyrene foam factory on Dalun Road in Dachun 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 becoming more frequent, and to prevent such incidents, the Fire Department has stipulated that fire-resistant coatings must be applied during the construction of factories. However, does fire-resistant coating actually prevent fires? Fire-resistant 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-resistant coatings, wood fire-resistant coatings, and steel structure fire-resistant coatings, with a wide range of applications. The fire-retardant mechanism of fire-resistant 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 reducing the rate of combustion. In addition to their flame resistance, fire-resistant coatings have a low thermal conductivity, which can delay the transfer of flame temperature to the protected material. When heated, fire-resistant coatings release non-flammable inert gases, diluting the flammable gases produced by the heated protected object.
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 then react with organic free radicals, breaking the chain reaction and lowering the 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 igniting or burning or from experiencing strength degradation due to temperature rise. The main characteristics of fire-retardant coatings are enhanced by micro-technology and formulation optimization, resulting in an excellent adhesion and strength of the intumescent carbonization layer, maintaining good adhesion even under strong air flow impacts, thereby completely solving the issue of carbonization layer delamination (the two-skin phenomenon). Long-lasting Corrosion Protection: By modifying the synthetic resin and micro-processing the raw materials, effectively addresses the poor corrosion resistance caused by physical defects in the raw materials, significantly improving the product's corrosion resistance and durability. Types of Fire-Retardant Coatings: This type of fire-retardant coating contains the resin.
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 familiar with the application process. Second, inspect the selected construction personnel for fire-resistant coating, inquire about relevant application information, such as precautions and steps, to prevent the presence of unqualified personnel. Third, have the construction personnel for steel structures perform a trial coating, observe the results. Unqualified personnel 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 situations.
Many fire-resistant coating companies aim to reduce the production costs of fire-resistant coatings while maintaining quality. 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 a 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, establish production facilities near the raw material market. Building closer to the market can increase production speed, lower transportation costs, and ultimately reduce the production costs of steel structure fire-resistant coatings. Thirdly, choose cost-effective raw material suppliers. The price of raw materials significantly influences the cost of steel structure fire-resistant coatings.
Interior steel structure fire-resistant coatings do not possess the same properties as exterior steel structure fire-resistant coatings and cannot withstand outdoor conditions, thus they are not suitable for outdoor fire protection. In contrast, exterior 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 requiring decorative effects within two hours. On the other hand, thick-coated steel structure fire-resistant coatings, with poor decorative properties, have a fire resistance limit of more than two hours and are used on steel structures that do not require decorative effects 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 protection and performance of the coatings. According to national regulations, the construction of steel structure fire-resistant coatings should be carried out by trained personnel. Sixthly, the fire-resistant coating layer was damaged during decorative work, welding, and dismantling of construction tools, and was not repaired in a timely manner. To ensure the fire resistance limit of the steel structure fire-resistant coating, the coating should be repaired promptly when damaged.
