What Is Spray Foam Equipment?
Spray polyurethane foam (SPF) is a spray-applied plastic that combines an isocyanate and polyol resin into a foam. It expands extensively at the point of application. It acts as an insulation and air barrier material to seal gaps, cracks, and cavities against air movement. Spray foam is a chemical-based insulation that is mixed on-site using spray foam equipment. Spray foam is available in two forms, open-cell and closed-cell. Closed-cell has a higher density and higher R-value. Open-cell is less durable than closed-cell spray foam. But based on the application, the padding consistency can be altered to increase the density.
What Is Spray Foam Equipment?
There are various use-cases of spray foam for commercial, roofing, housing, and industrial applications due to its efficacy as an air sealer and waterproofing agent. The efficiency of a spray foam application depends on the spray foam equipment used. The two relevant chemicals, 'A' and 'B,' are kept separately in the spray foam equipment. A chemical reaction produces foam only when the spray foam gun is triggered.
Based on your requirements, you can order spray foam equipment of the required capacity. You can buy spray foam machine for sale, which functions optimally and provides the power required for the spray foam application.
Pneumatic SPF Rig
A typical pneumatic spray foam rig includes the spray gun and transfer pumps that supply the materials from the gallon drums to the machines. The pneumatic equipment requires air to operate and thus includes electric air compressors to provide compressed air to the pneumatic equipment, as and when needed.
Spray guns are essential equipment for applying sprayed materials. They dispense and apply the mixed materials from the proportioning machines. To ensure that a spray gun remains continually useful, it must be purged once the spraying is complete. If any residue remains, it may harden over time and affect the mechanism of the spray gun. The three popular types of spray gun are:
· Mechanical purge spray foam guns: The mixing chamber consists of a valving rod that helps keep the chemical area separate until the gun is triggered. Since this gun consists of various intricate parts, the gun requires more maintenance. You must ensure that the valving rod is clean after use.
· Air purge spray foam guns: When you press the trigger, it initiates a movement in the mixing chambers that helps to combine the chemicals. It then results in a blast of air that helps to push out the chemicals. It is simple to use and does not require high maintenance. It is one of the most popular options.
· Solvent purge spray foam guns: This type of spray gun features a more complex design. It uses a chemical solvent to prevent a chemical reaction. The spray gun is primarily useful for coating applications.
These are some things you should know about spray foam equipment, which helps to successfully mix the chemicals on-site for spray foam applications.
