Clean Room Fireproof Door Manufacturer

Fireproof doors are mainly used in clean room decoration in biopharmaceutical, cosmetics, food, electronics, hospitals, new energy and other industries that require purification workshops. They are generally located on evacuation paths (such as stairwells, front rooms, walkways, etc.). A little carelessness in the detailed design of the building plane may cause the door leaf to block the evacuation path and reduce its effective width after opening, violating the basic requirements for personnel evacuation. This phenomenon is particularly prominent at turning points of evacuation routes and in high-rise residences, and should be taken seriously and avoided.
Classification according to function: Class A fireproof door, Class B fireproof door, Class C fireproof door.
Features:
1. Normally closed fireproof doors are usually used. Its door leaf is always closed. When people pass by, it is opened manually and the rear door leaf closes itself. Installing a push rod lock is more conducive to speeding up the evacuation.
2. The overlap between the door leaf and the door frame of a steel fireproof door shall not be less than 10mm, and the gap on both sides between the leaf and the door frame shall not be greater than 4mm. After installation and closing, the gap should not be too large, otherwise it will affect its airtightness, and it will also be difficult to reflect its role in inhibiting the spread of fire and smoke under fire conditions.
3.The surface is smooth and not easy to accumulate dust, easy to clean, and can be equipped with a window to look beautiful.

We have our own Clean Room Fireproof Door factory, so we can offer design Clean Room Fireproof Door Manufacturer & manufacturing. All these purification products are independently manufactured to ensure compatibility with various components of the system and achieve coordinated operation of the entire project.

How to choose the right fire door?

When choosing the right fire door, you need to consider multiple factors to ensure that it meets the safety needs and fire protection requirements of the building. Here are some suggestions for choosing fire doors, summarized in a clear format:

Fire rating:
Choose a fire door with an appropriate fire resistance rating based on the specific needs of the building and relevant laws and regulations.
Class A fire door: The highest level of fire door, with a fire protection time of not less than 1.5 hours, suitable for crowded places with high fire protection requirements, such as storage doors, fire equipment doors, etc.
Class B fire door: Intermediate fire door, with a fire protection time of not less than 1 hour, suitable for emergency exit doors, equipment rooms, places with high fire risks, etc.
Class C fire door: The lowest level of fire door, with a fire resistance limit of not less than 0.5 hours, mainly used for fire protection in transformer and distribution rooms, pipe well doors, etc.
Material:
Steel fire door: The material is high temperature resistant steel, filled with fireproof materials inside, with strong structural stability, suitable for high-rise buildings, emergency exits, etc.
Wooden fire door: Made of flame-retardant wood, it has a beautiful appearance, is light and convenient to open, and is suitable for home fire doors.
Steel-wood fire door: Combining the advantages of steel and wood, it has good fire stability and decorativeness.
Safety index:
Smoke resistance index: Ensure that the fire door can effectively isolate smoke.
Sealing index: The fire door should have good sealing performance to prevent the spread of fire.
Service life: Choose a durable fire door to ensure its long-term use effect.
Environmental performance: Consider whether the materials used for the fire door are environmentally friendly and pollution-free. Control the energy consumption of the fire door within a reasonable range.
Size and appearance: The size of the fire door needs to match the installation location. Choose the appropriate appearance design and color according to the decoration style.
Opening method: Choose the appropriate opening method according to the use occasion and convenience, such as normally open fire door (can be automatically closed by induction) or normally closed fire door.
Certification and standards: Ensure that the fire door complies with national and local fire safety specifications and standards, such as GB12955-2008 "Fire Door" and other relevant standards. Check if the fire door has the corresponding certification and certificate of conformity.
Cost: The cost of fire doors will vary depending on the material, fire rating, safety index and environmental performance. Choose the most cost-effective fire door within your budget.

Choosing the right fire door requires comprehensive consideration of multiple factors such as fire rating, material, safety index, environmental performance, size and appearance, opening method, certification and standards, and cost. By weighing these factors, you can choose a fire door that meets both building safety needs and budget requirements.

What types of fireproof materials are used to fill the inside of fire doors?

There are many types of fireproof materials filled inside fire doors. The following are several common fireproof materials and their characteristics:

Rockwool: Rockwool originated in Hawaii and is an insulating material made of molten rock fibers. Rockwool has good thermal insulation and high temperature resistance, which can effectively increase the fire resistance of fire doors. However, due to dust pollution problems, rockwool has been gradually eliminated by the market.
Perlite: Perlite is a non-toxic, odorless, non-flammable, and non-corrosive material for steel plates. Perlite does not melt or deform at a high temperature of 1100℃, and the combustion performance is tested to reach Class A, which meets the requirements of the new national standard for fire door filling materials.
Calcium silicon fireproof board: Calcium silicon fireproof board is a fireproof board composed of siliceous material and calcium material as the main raw materials, with reinforcing fibers added, supplemented by lightweight aggregates and adhesives. Calcium silicon fireproof board has excellent fireproof performance, and also has good sound insulation and heat insulation performance.
Needle-punched cloth phenolic insulation board: Needle-punched cloth phenolic insulation board is a new type of fireproof material that has been widely used in recent years. It is made of phenolic foam, and its main components are phenol and formaldehyde. Needle-punched cloth phenolic insulation board has the characteristics of non-toxic, non-combustible, low smoke, and high temperature resistance. The use temperature range is -250℃～+150℃. It overcomes the shortcomings of the original foam plastic insulation material, which is flammable, smoky, and deformed when exposed to heat, and retains the characteristics of the original foam plastic insulation material, such as light weight and convenient construction.
Aluminum silicate wool: Aluminum silicate wool is a fireproof material made of aluminum silicate fiber. Aluminum silicate wool has good fire resistance and thermal insulation properties, but it also has dust pollution problems and may be gradually eliminated by the market.
Cement: Cement is a common building material with good fire resistance. When making fire doors, cement can be used to fill the internal cavity of the door body to increase the structural stability and fire resistance of the door.
High-temperature plywood: High-temperature plywood is a board made of fire-resistant wood or glued wood. High temperature plywood has high fire resistance and can be used as the inner filling material of fire doors, providing good thermal insulation and fire resistance.
Refractory silicate: Refractory silicate is a special material with good fire resistance and thermal insulation. Refractory silicate can be used as the filling material of fire doors to provide additional high temperature protection.

When selecting the internal filling material of the fire door, it is necessary to comprehensively consider the fire resistance, environmental protection, cost and use occasion of the material. At the same time, it should be ensured that the selected material meets the relevant national standards and regulations.
