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 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 follow the manufacturer's product packaging instructions, generally without the need for water dilution. The coating should be applied in two or more coats, with a minimum of 500g/m². 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. Counterfeit fire-resistant coatings, however, will barely foam and will show a lot of chipping, and the wood substrate will quickly burn and deteriorate. (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-installed substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, and brush according to 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 foam formation. Normally, applying the specified amount (usually 500g/square meter) results in a foam layer thickness of over 20mm for first-grade fire-resistant coatings, and over 10mm 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-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 the same type of fire-retardant coating varies with the thickness applied. The appropriate coating thickness should be selected based on the building's fire resistance limit to ensure effective fire protection. Thirdly, the surface of the fire-retardant coating on steel structures may have issues due to two reasons: improper surface preparation and uneven application during coating. Fourthly, choosing 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 different parts of the steel structure ensures that the fire resistance limit meets fire safety requirements. Incorrect type selection means that even if the coating thickness is adequate, fire safety cannot be guaranteed. 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 - Coating integrity, no damage 0.6×10^3 kg/m^3
≥3d no visible change in packaging material, intact and undamaged; R≥0.05Mpa, when dropped from a height of 5m onto a concrete flat surface, no damage to the packaging; fireproofing material for Class 1 fire prevention with a fire resistance limit of ≥180min.
Fire incidents caused by reasons such as cabinet decay, 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 prevention knowledge for steel structures, people have also started to value the fire resistance of steel structures. Using fire-resistant coatings for steel structures is convenient and simple, and has gained widespread use. However, as more people use them, issues have been discovered. Due to the lack of understanding of fire-resistant coatings for steel structures, the purchased coatings may be: (1) Check whether the product has a qualified inspection report issued by the Fire Inspection Center, or you can also search online. Currently, fire-resistant coatings are subject to the fire product type recognition system, and fire-resistant coatings sold on the market should have a national fire product type recognition certificate and a type inspection 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 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 choosing.

(3) According to my 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, 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 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 significantly when exposed to intense heat from blowtorches, with the surface developing raised bubbles that will not burn through within minutes. In contrast, counterfeit fire-resistant coatings will barely foam and will shed large amounts of debris, and the wood substrate will quickly burn and deteriorate. (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-installed substrate, or apply a small amount of sample to 2 to 3 150mm x 150mm plywood sheets, and brush according to the actual application process. 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 foam formation.

Secondly, due to an unreasonable 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 limit, which is closely related to the coating thickness. 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 limit for effective fire protection. Thirdly, there may be surface irregularities 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 can be problematic. 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 is crucial to apply different types of fire-resistant coatings to different parts of the steel 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.
Indoor steel structural fire-retardant coatings lack some of the properties of outdoor steel structural fire-retardant coatings and cannot withstand outdoor conditions, thus they are not suitable for outdoor fire protection. Conversely, outdoor steel structural fire-retardant coatings can be used for indoor fire protection. Additionally, ultra-thin and thin-coat steel structural 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-coat steel structural fire-retardant 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 construction team for the steel structural fire-retardant coating is不合格. The quality of the construction directly affects the fire-retardant effect and performance of the coating. According to national regulations, the construction of steel structural fire-retardant coatings should be carried out by trained personnel. Sixthly, the decorative coating and welding, as well as dismantling tools, have damaged the fire-retardant coating layer, which was not repaired in a timely manner. To ensure the fire resistance limit of the steel structural fire-retardant coating, the coating should be repaired promptly when damaged.
A fire recently broke out at a polystyrene factory on Dalun Road, Dacun Town, Changhua County, with the flames spreading rapidly and dense smoke filling the air. Thankfully, no injuries were reported due to timely rescue efforts. It is well-known that fires are becoming more frequent. 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 directly contacting air, thus delaying ignition and reducing the speed of combustion. In addition to their flame resistance, these coatings have a low thermal conductivity, which delays the transfer of flame temperature to the protected material. When heated, fire-resistant coatings release non-flammable inert gases, diluting the flammable gases emitted during the heating decomposition of the protected object.
It makes it less flammable or slows down the burning rate. Nitrogen-based fire retardant coatings decompose upon heating to release groups like NO and NH3, which then react with free radicals, interrupting the chain reaction and lowering temperatures. 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 igniting or burning or experiencing strength decline due to temperature rise. The main characteristics of fire retardant coatings are enhanced through micronization technology and formula optimization, giving 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 off (two-skin phenomenon). Long-lasting Corrosion Resistance: By modifying the synthetic resin and micronizing the raw materials, the poor corrosion resistance caused by physical defects in the raw materials is effectively addressed, significantly improving the product's corrosion resistance and durability. Types of Fire Retardant Coatings: Intumescent Fire Retardant Coatings: This type of fire retardant coating contains the resin.
To ensure the qualification of steel structure fire-resistant coating application, 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. Review the qualifications of the construction team. Emphasize that the team should have fire-resistant coating application qualifications, which must be recognized by the fire supervision department. The construction staff should be trained and proficient in the application process. Second, inspect the selected fire-resistant coating construction personnel and inquire about related information. For example: precautions for fire-resistant coating application, application steps, etc., to prevent the presence of unqualified personnel. Third, have the steel structure fire-resistant coating personnel conduct a trial application, observing the results. Unqualified personnel should be replaced promptly. Fourth, to prevent issues with the construction staff, provide a brief training session to enhance their knowledge, thereby reducing 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. 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 of production staff for steel structure fire-resistant coatings. Skilled workers not only operate faster but also have higher production capacity. Therefore, strengthening the training of production staff for steel structure fire-resistant coatings is also a way to reduce production costs. Secondly, locate the factory for producing steel structure fire-resistant coatings near the raw material market. Establishing a factory closer to the market can increase production speed, reduce transportation costs, and ultimately lower the production costs of steel structure 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 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 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-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. Thicker-coated steel structure fire-resistant coatings, with poorer 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 the steel structure fire-resistant coating is不合格. The quality of the construction directly affects the fire-resistant coating's effectiveness. According to national regulations, the application of steel structure fire-resistant coatings should be performed 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 of the steel structure fire-resistant coating, the coating should be repaired promptly when damaged.
