Введение продукта:

The implementation standard for outdoor non expanding steel structure fireproof coating is GB14907-2018, which is similar to the implementation standard GB14907-2002 for outdoor thick steel structure fireproof coating. The principle of fire-resistant and thermal insulation of this coating: When the fire-resistant coating is exposed to fire, the coating basically does not change in volume, but the thermal conductivity of the coating is very low, which delays the speed of heat transfer to the protected substrate. The coating of the fire-resistant coating itself is non combustible, serving as a barrier and preventing thermal radiation to steel components, avoiding direct attacks from flames and high temperatures The process of some components in coatings reacting with fire to generate non combustible gases is endothermic and consumes a large amount of heat, which is beneficial for reducing the system temperature. Therefore, the fire prevention effect is significant and provides efficient fire and insulation protection for steel When this product encounters fire, the coating changes to form a glaze like protective layer, which can isolate oxygen and prevent it from coming into contact with flammable substrates, thereby avoiding or reducing combustion reactions Thick coated non expanding fireproof coating is a modern and excellent thermal insulation and fireproof coating for steel structures. It has the following characteristics: ☆ Putting people first, green and environmentally friendly, this product is a fireproof coating that has passed the China Environmental Labeling Product Certification. Early production time, mature technology, reasonable formula, and excellent weather resistance. Excellent fire resistance, able to withstand the test of the Great Fire at the Dongfang Ethylene Construction Site. ☆ Wide range of applications, such as fire protection for beams and columns of open-air steel structure frames in railway stations and petrochemical enterprises, fire insulation for steel pipelines, and fire protection treatment for indoor steel structures. Due to its characteristics of not corroding steel, not reacting chemically with any anti-corrosion primer, no irritating odor, light coating weight (relatively light structural load weight), large unit coating area, no smoke generated in the event of fire, and no release of harmful gases, this product is suitable for fire protection of steel structure surfaces in auditoriums, theaters, hotels, hospitals, office buildings, shopping malls, as well as factories, warehouses, and various industrial and civil buildings in industries such as petrochemicals, transportation, electronic telecommunications, and machinery manufacturing.

Метод строительства:

一、Grassroots treatment: Before construction, the dust, oil stains, and floating rust on the steel parts to be sprayed should be thoroughly removed, and alkali resistant and rust proof primer should be applied. 二、Bottom construction method: When applying fireproof coating to I-beams, H-beams, and rectangular steels with a width of less than 300mm, the base material should be roughened before applying the fireproof coating. When applying fireproof coating to I-beams, H-beams, and rectangular steels with a width of less than 300mm, mesh treatment must be carried out before applying the fireproof coating. Steel mesh or metal mesh can be selected and fixed with welded steel bars or bonded insulation nails. 三、 Construction of fireproof coating 1. The construction of the first layer of fireproof coating should be carried out by adding powder: glue: water=3:1:2 (the ratio of powder to glue can be adjusted appropriately according to the construction site). The fireproof coating should be mixed with a suitable amount of glue and water, and should be applied by spraying. The coating thickness is generally below 5mm. 2. Spray the first layer of fireproof coating when it is 70-80% dry (about 24 hours later); When the bottom layer is relatively dry, water can be sprayed to moisten it before proceeding with the construction of the second layer, starting from the second layer. The construction thickness of each layer can be between 8-10mm until it reaches the fire-resistant design thickness, and the construction can be carried out by spraying or brushing. 3. During interlayer construction, the surface of fireproof coating should not be smooth, but can be made into a rough surface, which is beneficial for the adhesion of the upper and lower layers. 4. When constructing on the top of the equipment skirt and steel structure, a 30 ℃ -45 ℃ groove should be made for the fireproof coating. After the coating dries, the top of the groove must be sealed with outdoor sealant. 5. During the summer construction of thick steel structure fireproof coatings, it is necessary to prevent the coating from drying too quickly, which may cause cracking or hollowing of the coating. The coating should be properly cured in a timely manner. Maintenance method: ① Cover the coating with plastic film to control the surface drying time. ② When scraping or intermediate layers during construction, an appropriate amount of reinforcing agent can be added, with a proportion of 5% to 8% of the powder Prevent direct sunlight from shining on the coating, sprinkle appropriate water on the coating surface to control the drying time of the coating surface, and reduce the cracking or hollowing phenomenon and range of the coating. 6. During winter construction, thick steel structure fireproof coatings should be protected against freezing and prevent the coating from freezing before it dries. The construction environment temperature should be above 5 ℃, and attention should also be paid to the construction time period. 7. Precautions: 1) The construction environment temperature should be between 5-35 ℃, and the relative humidity should not exceed 80%. During rainy days or when condensation forms on the surface of components, if the wind speed is greater than 5m/s, it is not suitable for operation. Before each coating is dry, it should be avoided from rain. 2) The material should be protected from moisture and rainwater infiltration, as it will become ineffective when exposed to moisture.
