Base treatment and construction methods
1.Substrate treatment:
1.1 Surface treatment of steel structures is the basic condition to ensure the durability of fire retardant coatings. According to different base materials, the surface treatment of steel structures should be as follows:
1.1.1 Surface of new ordinary steel structure
After the steel structure surface is sandblasted and derusted, a matching anti-rust and anti-corrosion coating is applied. It is recommended to use an epoxy zinc-rich primer + epoxy mica iron intermediate paint system.
1.1.2 Galvanized steel surface
In order to ensure good bonding performance with fire retardant coatings, epoxy coating transition paint must be used before construction.
1.1.3 Old steel structure or old primer surface
If the primer is not damaged and the surface is clean, check the compatibility of the fire retardant coating and the primer; if there is no primer or the primer is seriously damaged, the anti-corrosion coating must be removed and repainted before construction.
1.2 Before construction, thoroughly check whether the steel parts are painted with anti-rust paint, whether there is dust or oil stains, and whether there are cracks and improper welding on the steel beams and columns. Construction can begin only after the inspection shows that there are no problems.
1.3 Steel parts that have not been rust-proofed must be rust-proofed (this process is generally the responsibility of the user).
2. Ground floor construction:
Coating construction requires bottom layer reinforcement
Reinforcement method:
2.1 Welding hanging net
Welding steel rod
① Welding steel rods: The steel rods can be bent into an "L" shape with a No. 4 lead wire or a steel rod with a diameter of 4 mm, with a height of about 4cm, and welded to the steel component. The distance between top, bottom and left and right is about 40cm.
② When welding steel rods, pay attention to the welding of the inner and outer corners of the steel structure.
Hanging net:
① First, cut the expanded steel mesh into a reasonable length based on the actual situation of the steel structure on site.
② When hanging the net, pay attention to the pressing of the inner and outer corners of the steel structure, and do not raise it too much. Generally, the distance between the expanded steel mesh and the steel structure is 8~15mm.
③ Pay attention to the overlap of expanded steel mesh. Generally, the overlap length is more than 30mm.
2.2 Nail hanging net
Sticky nails
401 glue and ordinary cement can be mixed and bonded in a ratio of 1:1; two-component universal glue can also be used for bonding; or EVA707 glue and ordinary cement can be mixed and bonded in a ratio of 1:1. The distance between the insulation nails is about 20~30cm up and down, left and right. At the same time, when gluing insulation nails, pay attention to the bonding of the inner and outer corners of the steel structure.

2.3 Directly connect to the network
Lead wire mesh can also be used to reinforce the coating of the column. After the bottom layer of the steel structure is constructed and processed, lead wire mesh is added when the coating reaches about 10mm. The lead wire mesh is cut to an appropriate width according to the diameter (width) of the steel structure, usually 10cm. Overlap and tie with fire wire to fix.
3. Construction of fire retardant coating:
3.1 The first layer of fire retardant coating is a roughened layer:
Construction ratio: Coating powder: Napped glue = 2~1:1 (weight ratio) and appropriate amount of water (the amount of water added during batching can be determined according to the on-site construction conditions to facilitate construction). After stirring evenly, spraying or rolling can be used. The coating method is used for construction, and the coating thickness is 1~3mm. The next coat can only be applied after the roughened layer is completely dry (more than 24 hours at room temperature).
3.2 The proportion of other coatings:
Fire retardant coating powder: water = 1:0.8~1.2 (weight ratio) (the amount of water added during batching can be determined according to the on-site construction conditions to facilitate construction). After accurate measurement, add it to the mixer and stir. The stirring time depends on the ambient temperature. It may be modified according to the change. When the ambient temperature is above 15℃, the stirring time is 8~10 minutes; when the ambient temperature is 5~15℃, the stirring time can be appropriately extended.
3.3 The second layer of fire-retardant coating can be constructed by spraying or troweling. When applying, pay attention to compaction and avoid hollowing. The surface of the fire-retardant coating should not be too smooth. A rough surface can be made, which is beneficial to the bonding with the next layer of fire-retardant coating. When spraying, the spray gun should be perpendicular to the steel part to be sprayed, the distance is preferably 0.5~0.6 meters, the air pressure should be maintained at 0.6~0.8MPa, and the diameter of the spray gun mouth should be 8~12mm (if a self-weight spray gun is used, the diameter of the gun mouth should be 6-8mm) .
3.4 The second layer of fire-retardant coating should be constructed when the previous layer of fire-retardant coating is 70% to 80% dry (about 24 hours later). The construction thickness of each layer can be 6-8mm until the fire-retardant design thickness is reached. . During inter-layer construction, the surface of the fire-retardant coating should not be smooth but can be made into a rough surface, which is beneficial to the bonding of the upper and lower layers.
3.5 When the coating reaches about 10~15mm, wrap the steel mesh with an overlap of 5-10cm. After adding the mesh, use a spatula to compact the mesh in one direction, and pay attention to the compaction of the corners and joints; when coating When the layer reaches about 21~25mm, wrap the fiberglass mesh (or carbon fiber mesh), and overlap the mesh by 5-10cm. After adding the mesh, use a spatula to compact the mesh in one direction, and pay attention to the corners and connections. Compaction.
3.6 When constructing the top of the skirt and steel structure, a 30º~45º groove should be made with the fire retardant coating. After the coating is dry, the top of the groove must be sealed with outdoor sealant.
4.Self-check
After the construction of the fire retardant coating is completed, self-inspection can be carried out, mainly to check the thickness and appearance.
4.1 To check the thickness, you can make a homemade probe, mark the thickness, and test it in different areas of the steel structure. If the thickness does not meet the requirements, it should be repaired in time.
4.2 The superficial inspection mainly checks whether there are cracks and hollows on the surface of the fire retardant coating. If there are any, the reasons should be found in time and the cracks and hollows should be eradicated and repaired.
5. Maintenance
5.1 After the fire retardant coating is applied
5.2 After the product is formed, the coating can be sprinkled with water or other maintenance measures can be used to maintain the product where conditions permit.
Precautions for coating construction
1. During construction in northern areas with large climate and temperature differences, steel components must be treated with metal mesh. Fire retardant coatings in coastal humid areas should be protected.
2. It is not suitable for the construction of this product when the ambient temperature is lower than 5℃ in winter; it is not suitable for the construction of this product when the surface temperature of the substrate to be constructed is higher than 50℃ (ambient temperature ≥35℃) in summer.
3. During construction in the rainy season, the newly completed fire retardant coating should be protected from rain.
4. It is not suitable to operate when the wind speed is greater than 5m/s, or when there is condensation on rainy days or on the surface of components.
5. If the fire retardant coating construction needs to be interrupted or the coating repaired, a 30~40° slope should be left in the coating as the joint surface for the next continued construction or repair. Before construction and repair, the slope should be cleaned and moistened to ensure that the new and old surfaces are well combined.
6. Fire retardant coatings must be protected from rain and moisture during transportation and storage. Fire retardant coatings must not be used when they solidify and agglomerate.
7. After each construction, the equipment and tools used should be cleaned with clean water in time.
8. If there is a graded intersection operation during construction, safety should be paid attention to.
