EI concrete material fireproof duct is a product that creates a ventilation, air conditioning, pressure boosting, smoke extraction system with high safety and health protection for users. Although quite popular, however, not everyone understands this product well. Follow the article of P69 Mechanical Factory to understand more!

EI Fireproof ducts – Material: concrete

– EI Fireproof ducts – Material: concrete also has the same structure as conventional ducts, but the product is covered with protective outer layers of concrete. These protective layers are what make Ei ductwork able to withstand high temperatures according to the standards Ei 30, Ei 45, Ei 60, Ei 90, Ei 120.

– E (Integrity) is the limit level at which the material structure is perfectly maintained without breaking, falling, etc., regardless of the heat transfer capacity of the material. This limit is usually determined for application in fireproof solutions such as manufacturing partitions, walls, ventilation systems, etc.

– I (Thermal Insulation) is the limit at which the material retains stable thermal insulation ability. The main structure of the material is not damaged by heat. Determine this limit to apply to fireproof solutions, ensuring when a fire occurs, the materials are kept intact, the fire cannot spread, the temperature at the surfaces of the materials is guaranteed. tell.

EI concrete material fireproof ducts are covered with protective concrete layers outside to help EI ducts withstand high temperatures.

Structure of EI Fireproof ducts – Material: concrete

The product has high safety and fire resistance due to the following 4 layers:

– The first layer: Galvanized corrugated iron layer, minimum thickness of 0.75mm or more

– The second layer: Primer layer (Surface treatment paint, zinc …) to create roughness to increase adhesion, bonding between layers of materials with the corrugated iron surface. Reinforced wire mesh layer helps to bond between layers of materials and is more durable

– 3rd layer: Central insulation fireproof layer

– 4th layer: Fireproof paint layer

Construction conditions for EI ductwork

To achieve maximum efficiency, contractors need to pay attention to the following conditions

1. About basic requirements

– The surface of the material must be cleaned of grease and dirt

– Should be applied with a temperature above 10 degrees Celsius, air humidity below 85 degrees Celsius, no rain, splashing standing water on the surface

2. Thickness required protective layers

– The total thickness of the constructions must be according to the norm and meet the selected fire resistance standard

3. Dry time

– The lower the temperature, the longer the drying time

The higher the humidity, the longer the drying time

– Paint will dry faster when in a well-ventilated place

– Thickness will also affect the quick and slow drying time of the product
