Construction technology
Process
Technical specifications
The main material
Substrate processing
Clean the surface of steel components foreign body and rust, metal surface treatment of oil, to rust Standard ST2
 
Rust primer repair
Brush or spray twice with water-based or oily rust-proof primer to repair surface rust-proof steel components
Lanling inorganic zinc-rich primer or BA-601D water-based primer
Fire paint construction
Modulation to the appropriate construction viscosity, spraying or brushing the way of construction, control the thickness of each coating to prevent cracking, after a period of time before coating, until the specified thickness
Contego thin fire retardant coating

note
Construction Conditions:
1, the construction environment temperature is 5-40 ℃, the substrate temperature is 5-45 ℃, the air relative humidity is not more than 90%;
2, Maintain air circulation at construction site with wind speed no more than 5m / s, and should not be used for construction when outdoor work or construction components dew condensation;
