Fireproofing spray machine

Types of Fireproofing Spray Machines

The fireproofing spray machine is used to apply fireproof material evenly on the surface of structures or objects. Different types of fireproofing spray machines are available for various types of fireproofing materials and applications.

• Wet Mix Pumps:

Wet mix pumps are commonly used for fireproofing materials that need to be sprayed with water or other liquids. These pumps have adjustable pressure settings that allow them to dispense fireproofing materials with varying grain sizes smoothly. Wet mix pumps can be connected to external water sources or used with fireproofing materials that contain emulsions. This flexibility makes them suitable for applying fireproofing materials for concrete, intumescent coatings, etc.

Typical wet mix pump models include EP-75, MP-30, and MP-50.

• Dry Mix Blowers:

Dry mix blowers are used for fireproofing materials not requiring water or other liquids. These machines blow fireproofing materials, such as gypsum-based or cement-based products, onto the surface using compressed air. Dry mix blowers are lightweight and portable, making them suitable for dealing with inaccessible areas or limited space. They can apply fireproofing that meets the demands of different building areas, like the attics, concealed spaces, and wall cavities.

Typical dry mix blower models include C-100, C-500, and C-200.

• Hydraulic Spray Guns:

Hydraulic spray guns are devices used to apply fireproofing coating materials. These fireproofing spray machines work by atomizing and spraying the fireproofing coating onto the surface to be protected. Hydraulic spray guns offer several advantages for applying fireproofing coatings. They provide good control over the spray pattern and ensure even coverage. Hydraulic spray guns can be used for various fireproofing coating types, including intumescent and epoxy coatings.

• Hydraulic Spraying Machines:

These are the machines that spray the thick fireproofing materials that offer sound insulation directly onto the required surface using hydraulic pressure. Spraying with these machines ensures a more even coverage and uniform thickness of the fireproofing material, which is crucial for achieving the desired fire-resistance performance. The use of hydraulic pressure facilitates the application of dense and heavy-duty fireproofing materials. These materials include cementitious and mineral-based fireproofing substances.

Electric spray machines are alternatives to hydraulic machines for applying fireproofing materials. They are powered by electricity, eliminating the need for hydraulic connections or compressed air. Electric spray machines offer ease of use and versatility for applying various types of fireproofing materials, such as intumescent coatings, cement-based fireproofing, and acrylic-based fireproofing.

Choosing the suitable fire-resistive material and application method is essential for ensuring compliance and maintaining the integrity of the building's fire safety features.

Specifications and Maintenance of Fireproofing Spray Machines

Specifications

• Product Sizes:

  Generally, small machine will have a length, width, and height of about 800mm x 600mm x 900mm. Medium-sized machine will come with dimensions of approximately 1,000mm x 800mm x 1,200mm. For large capacity machines, the measurements will be around 1,200mm x 1,000mm x 1,500mm.

• Net Weight:

  Small fireproof sprayers usually weigh around 50kg. Medium ones will have a net weight of about 80kg. Large-scale machines will weigh up to 120kg or more. The heavy weight of larger models gives them more stable operation against vibrations.

• Operating Pressure:

  The pump can create a spraying pressure of 10-30MPa. A higher pressure means the material will be mixed better and will have a longer spraying distance.

• Power Source:

  These machines may use electricity, gasoline-powered generator, or diesel-powered hydraulic system. Electric motors usually supply 5-10kW.

• Material Tanks:

  The tank that holds fireproof material is generally around 200-500 liters in capacity.

Maintenance

• Daily Maintenance:

  Filling the fuel tank of the diesel pump or electric motor's driving unit should be done at the end of each working day. Cleaning the spray gun and mixing chamber is also done at the end of each day. Water or solvent is used to clean residue from the fireproof spray material. The machine should be stored under cover away from rain and sunlight.

• Weekend Maintenance:

  Every weekend, more thorough maintenance is done. This includes draining excess fuel from the tank and cleaning it. All moving parts are lubricated with grease. Machine fans and filters are checked to be in good working order. Reservoirs are checked for water or solvent residue and cleaned out. Tools required for this are a wrench set, cleaning brushes and rags, oil cans, and lubricant.

Scenarios of using fireproofing spray machines

The applications of fireproofing spray machines vary widely as these machines are suitable for many industries and structural categories. Generally speaking, the fireproofing spray machines are used to apply fireproof coating on construction materials. The fireproofing materials include the intumescent coating, cementitious coating, and epoxy coating among others. Using the fireproofing spray machine to apply these fireproofing materials ensures a quick and even application.

Fireproofing spray machines are popular across many fields because they can be used in various scenarios. Here are some common usage scenarios of fireproofing spray machines:

• Steel structure: Fireproofing spray machines are applied to steel structures like beams, columns, and trusses. Using the fireproofing spray machine to coat these steel structures improves the stability of the structure. The coating protects the steel structures from fire hazards.
• Industrial facilities: Fireproofing spray machines are widely applied to industrial facilities such as factories and manufacturing plants. Using the fireproofing spray machine to coat fire-retardant materials on exposed steel is very common.
• Public buildings: This kind of building includes shopping malls, hotels, and office buildings, among others. Fireproofing spray machines are applied to the steel skeleton of public buildings. These areas are usually susceptible to fire. Therefore, they need to be protected with fireproofing materials. Using a fireproofing spray machine ensures the fireproofing material covers the building evenly.
• Transportation infrastructure: Fireproofing spray machines can coat the fireproofing material evenly on transmission towers, bridges, and tunnels. This protects the infrastructure from fire damage.
• Automotive and aerospace industries: In the automotive and aerospace industries, fireproofing machines are frequently used to coat fireproofing materials on parts like engine components and structural elements. The fireproofing coating protects the parts from high temperatures and enhances fire resistance.

How to choose fireproofing spray machines

When purchasing fireproof spray machines for sale, it is essential to consider the factors that affect their performance, versatility, safety features, and efficiency. These will impact the buyers' experience and the scaffolding's reputation as a reliable supplier.
