NH-LY-03 indoor thick steel structure fireproof coating
NH-LY-03 indoor thick steel structure fireproof coating is the latest product developed by our factory. It replaces the previous two-component construction process of thick steel structure fireproof coating, making the construction process simpler and easier, and the adhesion , Good fire and heat insulation performance, 24mm coating thickness fire resistance limit can reach 3 hours.
Product composition < br Expansive vermiculite, high-strength binder, anisene fiber, high-temperature resistant material, heat-insulating material drying agent and other composite raw materials are made without volatile and harmful properties such as asbestos, formaldehyde and benzene .
Scope of application < br can be used for fire protection of steel structural members in construction projects.
Construction process < br The surface of the steel structure should be completely derusted, and the anti-rust paint should be applied twice, and the surface should be clean without dust and oil.
At the construction site, first mix the paint and water thoroughly (1: 1.5), and it is best to use an electric mixer to stir, so that the mixing is more uniform.
Note: In order to disperse and dissolve the materials in the coating better, you need to wait for 30 minutes and stir again before spraying.
The coating is applied by spraying.
The thickness of the first coat cannot exceed 5mm. After the first coat is dry, the second coat is sprayed. The thickness of the coat can be increased appropriately. Generally, it can reach 25mm by spraying 4-5 times.
Note: The coating with good mixing ratio should be used within 12 hours.
When the air temperature is lower than 0 ° C on that day, no construction is allowed when the wind is greater than 5 degrees.
Construction should be carried out in a well-ventilated room, and no construction should be carried out when there is rain in the outdoor construction.
Fire resistance < br The coating thickness is 24mm, the fire resistance is not less than 3 hours, and the dosage is about 10 kg per square meter.
Packaging, storage and transportation < br Packing is a textile bag with a net weight of 25 kg. It must be protected from moisture during transportation and storage. The validity period is six months.
When used, about (kg / ㎡)
