Avoid enterprises from passing off substandard products as high-quality ones, failing to achieve fire protection effects. (3) According to the author's understanding, currently, fire-resistant coatings produced by domestic enterprises that meet the second-level fire-resistant standards are priced at over 8,000 yuan per ton. If the selling price is lower than this, the quality is questionable. (4) The on-site application of fire-resistant coatings should follow the instructions on the product's outer packaging by the manufacturer. Generally, no water dilution is required, and the coating should be applied in two or more coats, with a minimum of 500 grams per square meter. When fire-resistant coatings are watered down or insufficiently applied, it will greatly 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 flames like those from a blowtorch, with surface bulging but no burn damage within minutes. Counterfeit fire-resistant coatings, however, will not foam much and will show a lot of loose flakes, with the wooden substrate also quickly burning and breaking. (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-installed substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, and apply it according to the actual construction 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 for foaming. Normally, when applied at the specified rate (usually 500g/square meter), the foam layer thickness of the first-grade fire-resistant coating should be over 20mm, and the second-grade fire-resistant coating should be over 10mm, with a uniform and dense foam layer. (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 usually 350 to 500g/square meter, while the topcoat application rate is usually 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 to 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 result in varying fire resistance limits. It is essential to select the appropriate coating thickness based on the building's fire resistance limit for effective fire protection. Thirdly, the surface of the fire-retardant coating on steel structures may have issues, primarily due to improper base treatment and uneven application during coating. Fourthly, choosing the wrong type of fire-retardant coating can be problematic. Different types of coatings have different thickness requirements on steel structures, and their fire resistance limits vary. It is crucial to apply different types of fire-retardant coatings to different parts of the steel structure to ensure the fire resistance limit meets safety standards. Incorrectly selecting the type of coating, even if the thickness is correct, does not guarantee fire safety. Fire-retardant coatings for steel structures can be categorized as indoor or outdoor, and should be transported as ordinary solid substances to prevent rain and direct sunlight exposure. Performance indicators: Appearance, loose density, water resistance, oil resistance, compressive strength, drop resistance, fire resistance – complete and undamaged coating, 0.6×10^3 kg/m^3.

Material inside the package shows no significant changes within 3 days; package is intact with no damage. When the package is dropped from a height of 5m onto a concrete level surface, the material shows no damage. First-grade fireproof sealing material has a fire resistance limit of ≥180min.

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, issues have been discovered. Due to the lack of understanding of fire-resistant coatings for steel structures, the purchased coatings may be: (1) Verify whether the product has a qualified inspection report issued by the Fire Prevention 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 a national type recognition certificate for fire products and a type inspection report of qualified. (2) According to national standards, in addition to meeting fire resistance requirements, the combustion performance of fire-resistant coatings is divided into Level 1 and Level 2. Under the specified test conditions, the combustion resistance 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 differentiate when choosing.

Avoid businesses from selling substandard products that do not 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) 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 significantly when exposed to intense heat from blowtorches, with the surface bulging without burn damage within minutes. On the other hand, counterfeit fire-resistant coatings will barely foam and will shed large amounts of debris, and the wooden substrate will quickly burn and deteriorate. (6) If possible.

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 sample to 2 to 3 150mm x 150mm plywood sheets, and apply as per the actual installation process. After drying, inspect with the flame of an alcohol lamp. The flame height should be around 40mm, and the duration of flame application is typically 20 minutes, to check for foam formation. Under normal circumstances, applying the coating in the specified quantity (usually 500g per square meter) should result in a foam layer thickness of over 20mm for Class 1 fire-resistant coatings, and over 10mm for Class 2 fire-resistant coatings, ensuring the foam layer is even and dense. (7) In actual use, to ensure the fire-resistant properties and other performance of the fire-resistant coating, a transparent topcoat is generally required. The application rate for fire-resistant coatings is usually 350 to 500g per square meter, while the topcoat application rate is typically 50g per square meter.

Different thicknesses of the same fire-resistant coating result in varying fire resistance limits. It is essential to choose the appropriate coating thickness based on the building's fire resistance requirements for effective fire protection. Thirdly, during construction, the surface of the fire-resistant coating on steel structures may exhibit issues, caused by two main factors: improper surface preparation and uneven application during coating. Fourthly, selecting the wrong type of fire-resistant coating during application is problematic. Different types of coatings have varying thickness requirements on steel structures and different fire resistance limits. To ensure the steel structure meets fire safety requirements, it is crucial to apply different types of fire-resistant coatings to different parts of the structure. If the wrong type is chosen, even if the correct thickness is achieved, 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 lack some properties of exterior steel structure fire-resistant coatings and cannot adapt to outdoor environments, thus they are not suitable for outdoor fire protection. In contrast, exterior steel structure fire-resistant coatings can be used for interior 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 poorer 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 selected construction team 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 decoration, 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.

Recently, a polystyrene factory on Dalun Road in Dachun Town, Changhua County, caught fire, with the flames spreading rapidly and thick smoke filling the air. Thankfully, due to timely rescue efforts, there were no casualties. It is widely known that fires are becoming more frequent. To prevent fires, the Fire Department has stipulated that fire-retardant coatings must be applied during factory construction. However, can fire-retardant coatings really 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: Fire-retardant coatings are inherently flame-retardant or non-flammable, preventing the protected material from coming into direct contact with air, thus delaying ignition and reducing the rate of combustion. Besides being flame-retardant or non-flammable, they 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 by the protected material upon heating.

It makes it less flammable or slows down the burning rate. Nitrogen-containing fire-retardant coatings decompose upon heating to release groups like NO and NH3, which then react with organic free radicals, interrupting the chain reaction and lowering temperatures. Expanding fire-retardant coatings heat up and foam, forming a carbonaceous 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 experiencing strength reduction due to temperature rise. The main characteristics of fire-retardant coatings are achieved through micronization technology and formula optimization, resulting in an excellent adhesion and strength of the expanding carbonization layer, maintaining good adhesion even under strong air flow impacts, and completely solving the issue of carbonization layer delamination (two-skin phenomenon). Long-lasting corrosion resistance: By modifying synthetic resins and micronizing raw materials, it effectively addresses the poor corrosion resistance caused by physical defects in raw materials, significantly enhancing 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 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 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 the presence of unqualified personnel. Third, have the fire-resistant coating construction personnel perform a trial application and observe the results. Unqualified applications should be replaced promptly. Fourth, to prevent issues with the construction personnel, provide them with a brief training session to enhance their knowledge, thereby reducing the likelihood of discovering non-compliant situations.

Many fire-retardant coating companies strive to reduce the production costs of fire-retardant coatings while maintaining quality unchanged. To be honest, it's quite challenging. However, Beijing Xingkun Fire Protection Materials Co., Ltd. is here today to show you how to achieve this goal, and more importantly, to ensure that the quality and effectiveness of the fire-retardant coatings do not diminish. Firstly, enhance the training of production personnel for steel structure fire-retardant coatings. Skilled workers operate more quickly and efficiently. Therefore, improving training for production staff is also a way to lower production costs. Secondly, choose a location close to the raw material market for the factory production of steel structure fire-retardant coatings. Building closer to the market can increase production speed, reduce transportation costs, and ultimately lower the production costs of steel structure fire-retardant coatings. Thirdly, select low-cost raw material suppliers. In the cost of steel structure fire-retardant coatings, the price of raw materials largely determines the total cost.

Indoor steel structure fire-retardant coatings lack some properties of outdoor steel structure fire-retardant coatings and cannot withstand outdoor conditions, thus they are not suitable for outdoor fire protection. Conversely, outdoor steel structure fire-retardant coatings can be used for indoor fire protection. Additionally, ultra-thin and thin-coated steel structure fire-retardant 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. Thick-coated steel structure fire-retardant 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 more than two hours. Fifthly, the selected construction team for steel structure fire-retardant coating 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 fire-retardant coating layer was damaged during decorative work, welding, and dismantling of tools, and was not repaired promptly. To ensure the fire resistance limit of the steel structure fire-retardant coating, repairs should be made promptly when the coating is damaged.
