(1) Prevent businesses from selling substandard products that fail to meet fire protection standards. (3) According to the author's research, currently, fire-resistant coatings produced by domestic companies that meet Level 2 fire protection standards 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, and 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 watered down or not applied sufficiently, it will greatly affect 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 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 barely foam and will shed large amounts of particles, and the wooden base material will quickly burn and deteriorate. (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 panels, and brush it according to the actual application process. After it dries completely, 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 foam formation. Under normal circumstances, applying the specified amount (usually 500g/square meter) should result in a foam layer thickness of 20mm or more for first-grade fire-resistant coatings, and 10mm or more for second-grade fire-resistant coatings, 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 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 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 thickness of the coating applied. 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 limit to ensure effective fire protection. Thirdly, during construction, the surface of the fire-resistant coating on steel structures may have issues, which can be attributed to two factors: improper surface preparation and uneven application during coating. Fourthly, selecting the wrong type of fire-resistant coating during application is a common mistake. Different types of coatings require different thicknesses for application on steel structures, and their fire resistance limits vary. To meet fire resistance requirements, it is crucial to use different types of coatings for different parts of the steel structure. 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, 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 - coating is intact with no damage, 0.6×10^3 kg/m^3.

Fires caused by reasons such as the rotting of distribution cabinets, aging of wiring, 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 prevention knowledge for steel structures, people have also begun to value the fire resistance of steel structures. The use of fire-resistant coatings for steel structures is convenient and simple, and has become widely used. 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) Check if 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 product type recognition system for fire products, and the fire-resistant coatings sold on the market should have a national fire product type recognition certificate and a type inspection qualification report. (2) According to national standards, in addition to meeting fire resistance requirements, the combustion properties of fire-resistant coatings are divided into level one and level two. Under the specified test conditions, the burn 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 distinguish between these when choosing.
Avoid businesses from passing off inferior products as high-quality ones, which fail to meet fire protection standards. (3) According to my understanding, currently, fire-resistant coatings produced by domestic companies that meet grade two fire protection standards 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 be guided by the product's outer packaging instructions from the manufacturer. Generally, no water dilution is required, and the coating should be applied in two or more coats, with a minimum thickness of 500g per square meter. When fire-resistant coatings are diluted with water or applied insufficiently, it greatly affects 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 bulging without burning for several minutes. On the other hand, counterfeit fire-resistant coatings barely foam and will shed large amounts of debris, and the wooden base material will quickly catch fire and deteriorate. (6) If possible.

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 foaming of the coating. Under normal circumstances, applying the coating in the specified quantity (usually 500g per square meter) results in a foam layer thickness of over 20mm for first-grade fire-resistant coating and over 10mm for second-grade fire-resistant coating. 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.

Applying different types of coatings to various parts of the steel structure ensures that the fire resistance limit meets fire safety requirements. 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 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. Conversely, 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. In contrast, 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 selected steel structure fire-resistant coating construction team is不合格. The quality of steel structure fire-resistant coating construction directly affects the fire-resistant properties and performance of the coating. According to national regulations, the construction of steel structure fire-resistant coatings should be carried out by trained personnel. Sixthly, the fire-resistant coating coating 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.
A polystyrene foam factory on Dalun Road in Dachun Township, Changhua County, recently suffered a fire, with the flames spreading rapidly and thick smoke filling the air. Fortunately, due to timely rescue efforts, no casualties occurred. It is widely known that fires are becoming more frequent. To prevent such incidents, the fire department has stipulated that fire-retardant coatings must be applied during the construction of factories. However, does fire-retardant coating actually prevent fires? Fire-retardant coatings are a type of flame-retardant paint made from various materials, including 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, thus delaying ignition and slowing down the rate of combustion. In addition to their flame resistance, fire-retardant coatings 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 object upon heating.
Make it less flammable or slow down the burning rate. Nitrogen-containing fire-retardant coatings decompose upon heating to release groups such as NO and NH3, which then combine with organic free radicals, interrupting the chain reaction and lowering the temperature. Intumescent fire-retardant coatings expand and foam upon heating, 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 from experiencing strength degradation due to temperature rise. The main characteristics of fire-retardant coatings are achieved through micronization technology and formula optimization, which give the intumescent carbonized layer excellent adhesion and strength, maintaining good adhesion even under strong air flow impacts, and completely solving the issue of carbonized layer peeling (double skin phenomenon). Long-lasting Corrosion Protection: By modifying synthetic resins and micronizing raw materials, 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 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. The construction personnel should be trained and proficient in the construction process. Secondly, inspect the selected construction personnel for fire-resistant coating application and inquire about relevant information, such as precautions and steps for applying fire-resistant coatings, to prevent the presence of unqualified personnel. Thirdly, have the fire-resistant coating construction personnel perform a trial application and observe the results. Unqualified applications should be replaced promptly. Fourthly, to prevent issues with the construction personnel, provide them with a brief training session to enhance their knowledge, thereby reducing the likelihood of discovering unqualified work.
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. 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 do not degrade. 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. A shorter distance to the raw material market can increase production speed and reduce transportation costs, thereby lowering the production costs of steel structure fire-resistant coatings. Thirdly, select cost-effective raw material manufacturers. The cost of steel structure fire-resistant coatings is largely determined by the price of raw materials.
Interior steel structure fire-retardant coatings do not possess the same properties as exterior steel structure fire-retardant coatings and cannot withstand outdoor conditions, thus they are not suitable for outdoor fire protection. Conversely, exterior steel structure fire-retardant coatings can be used for indoor fire protection. Additionally, ultra-thin and thin-coat 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. In contrast, thick-coat steel structure fire-retardant coatings, with poor decorative properties, have a fire resistance limit exceeding two hours and are used on structures that do not require decoration for more than two hours. Fifthly, the selected construction team for the steel structure fire-retardant coating is不合格. The quality of the steel structure fire-retardant coating's application directly affects its fire protection and performance. According to national regulations, the application of steel structure fire-retardant coatings 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.
