Steel structure fireproof coating construction manufacturer, steel structure fireproof coating manufacturer, steel structure fireproof coating manufacturer acceptance

  Steel structure fireproof coating construction manufacturer, steel structure fireproof coating manufacturer, steel structure fireproof coating manufacturer acceptance
The indoor steel structure fireproof coating is painted on the surface of indoor steel members
When the steel structure fireproof coating meets fire, the coating expands and foams to form a carbonized fire-resistant and thermal insulation protective layer, isolate oxygen, delay the heating speed of steel structure, avoid the rapid temperature rise of steel members, and improve the fire-resistant time limit of steel structure
The fireproof coating for steel structure can meet the requirements of fire protection with a fire resistance time of 0
5h ~ 2
5h
The fireproof coating for steel structure is applicable to columns, beams, roof bearing components and evacuation stairs supporting a single layer in the building design fire resistance rating of class I; Steel structural members supporting single-layer and multi-layer columns, beams, roof load-bearing members and evacuation stairs in class II ~ IV fire resistance rating
Characteristics of fire retardant coatings for steel structures

Construction technology of fireproof coating for steel structure
Before the application of fireproof coating, the rust removal and antirust primer coating on the surface of steel members shall meet the design requirements and current relevant specifications, and the dust, oil stain and other sundries on the surface of steel members shall be completely removed
Fire retardant coating shall be applied before interior decoration and under the condition that it will not be damaged by subsequent works
During construction, walls, doors and windows, mechanical equipment and other components that do not need fire protection shall be shielded
Before coating, the coating shall be fully stirred evenly
If the coating is too thick, an appropriate amount of water can be added and diluted until it is suitable for coating and does not flow
The fireproof coating of steel structure is suitable to be painted by spraying method
Spray evenly with a bucket gun with a diameter of 6 ~ 8mm under the pressure of 0
4 ~ 0
6MPa
The thickness of the first spraying should cover the surface anchor of the base course, generally no more than 1mm; The next coating can be carried out after the previous coating is dry; The brushing thickness of each pass can be appropriately increased from the second pass, but it is better not to flow

Precautions for fire retardant coating of steel structure
During the construction process and before the coating is dried and solidified, the ambient temperature should be kept at 5 ~ 45 ℃, the relative humidity should not be greater than 90%, and the air should be circulated
When there is condensation on the component surface, it is not suitable for construction
During construction, pay attention to measure the thickness of the coating at any time according to the fire resistance limit
When spraying, pay attention to the consistent spraying direction to avoid the inconsistent direction of concave convex texture, resulting in light perception color difference
This product is a water-based fire retardant coating, so the coating should be indoors or in a rain shelter to avoid rain during or after construction

Reference dosage of fireproof coating for indoor steel structure
　　1
2kg/㎡/mm。
Identification method of fire retardant coatings for steel structures
1 consumers can investigate whether the steel structure fire retardant coating has the qualified inspection report issued by the fire quality inspection center
At present, China's fire retardant coating implements the fire product type approval system
Therefore, if there is no corresponding inspection report for the fake thin steel structure fire retardant coating product, its product must be fake fire retardant coating

2 consumers can also test by sampling
According to the standard, in addition to meeting the fire resistance requirements, the fire resistance time of ultra-thin fire retardant coating shall not be less than 2 hours after brushing
Through the experiment, consumers can avoid dealers from shoddy and deceived

If the price of fireproof coating is lower than 7000 yuan, consumers should not be deceived if the price is lower than 7000 yuan

4 insiders pointed out that the reference dosage of thin steel structure fire retardant coating is 2kg / ㎡ / mm, while some dealers either unilaterally exaggerate the effect or do not talk about the dosage, which consumers need to pay attention to

5 qualified thin steel structure fire retardant coatings are environmental protection products, and their VOC content can be determined to identify the true and false

Packaging and storage of fireproof coating for steel structure
1
Packaging: 25kg / barrel; 20kg / barrel

 
2
Storage: store in a ventilated and dry warehouse with a temperature of 5 ~ 45 ℃, isolate the fire source and keep away from the heat source to prevent freezing or exposure
The shelf life is 6 months
