Fire Door A special door
Fire door factory production of a full range of fire doors
Fire door is a special door, its main role is not anti-theft, but fire, the material is the use of very high purity steel, this material is not burning in the fire, can effectively control the fire, and according to statistics Most of the casualties in the fire were caused by smoke that caused the person's breathing to be blocked and caused death due to inhalation of too much toxic substances or suffocations. In the face of this situation, people should first use moisturizing cloth to cover their nose and mouth and try The lower position of the breath, you can make a lot of inhaled toxic substances reduction, this time if there are special doors for fire should be quickly pulled down to ensure that smoke will not enter the unburned fire space, and then further self-help or Help.
Have to say is because many businesses are not willing to fire investment and refused to install fire doors, so that once the fire is difficult to get control, it is very incorrect practice, to know that human life is much higher than a safe The value of the door, even without considering life, the use of fire equipment can also make economic losses in the fire get very good control, it is still advising the responsible person in the public places in charge of the installation of such fire tools, especially some Flammable place.
Steel fire door materials and production process introduced
Door frame manufacturing process: According to the technical quality of the processing unit details of the size, specifications, the raw materials 1.2mm galvanized steel strip cutting, punching, bending, welding, grinding, rust acid pickling (chemical material water), painting spray Plastic (sent to the coating equipment workshop for electrostatic spraying, the plastic powder sprayed on the door frame surface, the coating equipment drying Road 180 ℃ to 205 ℃ high temperature melting plastic powder), paste the fire expansion and film packaging.
Doppler manufacturing process: According to the technical quality of the processing unit details of the size, specifications, the raw materials 0.8mm galvanized steel sheet cutting, punching, bending, filling materials (filling material using perlite door core board 14kg / ㎡, polyurethane foam (Chemical material water), painting spray (sent to the coating equipment workshop for electrostatic spraying, the plastic powder sprayed on the door frame surface, the surface of the door, By painting equipment drying tunnel 180 ℃ to 205 ℃ high temperature melting plastic powder), plastic film packaging.
National standards on the fire door at the junction of the size of the gap has a clear requirement: the steel fire door, requiring its fan and door frame overlap shall not be less than 10mm, fan and the door between the two sides of the gap shall not be greater than 4mm. Fire doors installed after the closure of the gap can not be too large, otherwise the fire door sealing performance is difficult to guarantee, it is difficult to reflect its fire conditions to suppress the spread of fire and smoke.
