(Avoid businesses from selling substandard products that fail to meet fire protection standards.)(3) According to the author's understanding, currently, fire-retardant coatings produced domestically that meet Grade 2 fire-resistant standards 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-retardant coatings should follow the instructions on the product's outer packaging by the manufacturer. Generally, it does not require dilution with water. It should be applied in two or more coats, with a minimum of 500 grams per square meter. If the fire-retardant coating is diluted with water or applied insufficiently, it will greatly affect its fire-retardant properties. Fire departments should strengthen supervision at construction sites to prevent contractors from cutting corners.(5) Genuine fire-retardant coatings will expand and foam when exposed to intense flames like those from a blowtorch, with surface bulging within minutes without any burn damage. On the other hand, counterfeit fire-retardant coatings will not expand and will shed a large amount of debris, with the wood substrate also likely to burn and break quickly.(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-applied substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, 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 about 20 minutes to check for bubbling. Under normal circumstances, applying the specified amount (usually 500g/square meter) of fire-resistant coating should result in a foam layer thickness of over 20mm for grade 1 fire-resistant coating and over 10mm for grade 2 fire-resistant coating, with the foam layer being even and dense. (7) In actual use, to ensure the fire-resistant properties and other performance of the coating, it is generally necessary to use a transparent topcoat. The amount of fire-resistant coating typically ranges from 350 to 500g/square meter, while the topcoat is usually applied at a rate of 50g/square meter. Secondly, due to an不合理 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. The fire resistance limit of similar fire-retardant coatings varies with the thickness applied. It is essential to select the appropriate coating thickness based on the building's fire resistance limit for effective fire protection. Thirdly, during construction, the surface of the fire-retardant coating on steel structures may exhibit issues due to two reasons: improper surface preparation and uneven application during coating. Fourthly, choosing the wrong type of fire-retardant coating during application. Different types of fire-retardant coatings require different thicknesses when applied to steel structures, and their fire resistance limits vary accordingly. Applying different types of fire-retardant coatings to various parts of the steel structure ensures that the fire resistance limit meets fire safety requirements. Choosing the wrong type can result in inadequate fire protection even if the coating thickness is correct. Fire-retardant coatings for steel structures can be categorized into indoor and outdoor varieties, and they should be transported as ordinary solid substances to prevent rain and direct sunlight. Performance specifications: Appearance, loose density, water resistance, oil resistance, compressive strength, drop resistance, fire resistance – intact, no damage 0.6×10^3 kg/m^3

Within 3 days, no visible changes in the packaging material; intact and undamaged packaging. At a height of 5m, free-falling onto a concrete flat surface with a force of R≥0.05Mpa, the packaging remains undamaged. Fire-resistant sealing material meets a fire resistance limit of ≥180 minutes.

Fire incidents in enterprises are most commonly caused by reasons such as cabinet decay, aging wiring, equipment short-circuits, and improper operation of electrical equipment. The main reason is that as the knowledge of fire prevention in steel structures is promoted, people have also started to value the fire resistance of steel structures. Using fire-resistant coatings for steel structures is convenient and simple, which has led to their widespread use. However, with the increase in users, some issues have been discovered. Due to the 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 check online. Currently, fire-resistant coatings are subject to the type approval system for fire products, and the fire-resistant coatings sold in the market should have a national type approval certificate for fire products and a type inspection report. (2) According to national standards, in addition to meeting fire resistance requirements, the combustion performance of fire-resistant coatings is divided into Grade I and Grade II. Under the specified test conditions, the combustion resistance time of Grade I fire-resistant coatings should not be less than 20 minutes, and the heat resistance time of Grade II fire-resistant coatings should not be less than 10 minutes. Users should pay attention to the distinction when choosing.

Avoid businesses 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 level two fire resistance 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 product packaging instructions, generally without the need for water dilution. The application should be done in two or more coats, with each coat not less than 500 grams per square meter. When fire-resistant coatings are diluted with water or applied insufficiently, it will greatly affect their fire resistance. Fire departments should strengthen supervision on construction sites to prevent contractors from cutting corners. (5) Genuine fire-resistant coatings will foam and expand significantly when exposed to high heat from blowtorches, with the surface bulging but no burn damage within minutes. On the other hand, counterfeit fire-resistant coatings will not foam much, will have a lot of falling debris, and the wooden substrate will 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 pre-applied substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, and paint according to the actual application process. After drying, inspect with the flame of an alcohol lamp. The flame height should be about 40mm, and the flame should be applied for about 20 minutes, checking for the foaming of the coating. Normally, when applied at the specified rate (usually 500g per square meter), the foam layer thickness of a Class 1 fire-resistant coating should be over 20mm, and that of a Class 2 fire-resistant coating should be over 10mm, with the foam layer being uniform 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 apply a clear topcoat. The application rate of fire-resistant coating is typically 350 to 500g per square meter, while the topcoat is usually 50g per square meter. Secondly, due to an不合理 construction plan, the fire-resistant coating on the painted steel structure is excessively thin.

The purpose of applying fire-resistant coatings to steel structures is to enhance their fire resistance limits, which are closely related to the coating thickness. Different thicknesses of the same fire-resistant coating lead to 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 have issues, caused by two 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 and fire resistance limits on steel structures. Applying different types of coatings to different parts of the steel structure ensures that the fire resistance limit meets fire safety standards. Choosing the wrong type can result in inadequate fire protection, even if the coating thickness is correct. 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 indoor fire protection. Additionally, ultra-thin and thin-coating 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-coating 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 steel structure fire-resistant coating's construction directly affects its fire protection and performance. 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 and welding, as well as during the 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 foam factory on Dalun Road in Dachun Town, Changhua County, caught fire. The flames spread quickly, with dense 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 really prevent fires? Fire-retardant coatings are made from a variety of materials, including film-forming agents, flame retardants, and foaming agents, and are commonly categorized into decorative fire-retardant coatings, wood fire-retardant coatings, and steel structure fire-retardant coatings, among others, with a wide range of applications. The fire-retardant mechanism of fire-retardant coatings: These coatings are inherently flame-resistant or non-flammable, preventing the protected material from coming into direct contact with air, thus delaying ignition and reducing the rate of combustion. In addition to 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.

It makes the material less flammable or slows 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. Expanding fire retardant coatings expand and foam when heated, 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 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, even under strong airflow impact, thereby completely solving the issue of carbonization layer peeling (double skin phenomenon). Long-lasting Corrosion Protection: By modifying synthetic resins and micronizing raw materials, effectively addresses the issue of 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 qualification of fire-resistant coating on steel structures, a key highlight is selecting both qualified fire-resistant coatings for steel structures and a competent construction team. Below, we introduce how to choose a construction team for steel structure fire-resistant coatings. Check the qualifications of the construction team. The emphasis is on verifying that the team has the necessary fire-resistant coating construction qualifications, which must be recognized by the fire supervision department. Construction personnel should be trained and familiar with the construction process. Second, inspect the selected construction personnel for steel structure fire-resistant coatings, inquire about relevant information on fire-resistant coating construction. For instance: precautions for fire-resistant coating construction, steps of fire-resistant coating construction, etc., to prevent the presence of unqualified personnel. Third, have the steel structure 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 a brief training session to enhance their knowledge. This helps reduce the likelihood of discovering unqualified situations.

Many fire-resistant coating companies aim to reduce production costs while maintaining quality. To be honest, it's challenging, but today, Beijing Xingkun Fireproof Material Co., Ltd. reveals how to achieve this goal. More importantly, it is crucial to ensure that the quality and effectiveness of the fire-resistant coatings are not compromised. Firstly, enhance training for the production staff of 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 is also a way to lower production costs. Secondly, locate the factory closer to the raw material market for producing steel structure fire-resistant coatings. A shorter distance between the factory and the market can increase production speed, reduce transportation costs, and ultimately lower the production costs of steel structure fire-resistant coatings. Thirdly, choose affordable raw material suppliers. The price of raw materials greatly influences the cost of steel structure fire-resistant coatings.

Indoor steel structure fire-resistant coatings lack some of the properties of outdoor steel structure fire-resistant coatings and cannot withstand outdoor conditions, thus they are not suitable for outdoor fire protection. Conversely, 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 requiring decorative effects within two hours. In contrast, thick-coated 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 more than two hours. Fifthly, the construction team chosen for the steel structure fire-resistant coating is不合格. The quality of the steel structure fire-resistant coating's application directly affects its fire protection and performance. According to national regulations, the application 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 promptly. To ensure the fire resistance limit of the steel structure fire-resistant coating, the coating should be repaired promptly when damaged.
