Points to note when choosing a Polyurethane Foam Spray Machine

PU materials are being widely applied in many areas of life. When constructing karaoke rooms, cold storage, … or many projects that require heat insulation, soundproofing, waterproofing, the “Pufoam sprayer” is an indispensable device. Do you have a good understanding of this machine or not?

How does pu foam injection machine work? Polyurethane pu foam machine, Polyurethane foam, homogeneous rigid foam is formed by the combination of two separate raw materials called Polyol (B) Isocyanate (A). Requires high-tech machinery and equipment. These systems include chemical dosing pump, mixing nozzle, air compressor . With continuous coating, it completely removes thermal bridges, it swells to 30-40 times its own volume within seconds and becomes polyurethane foam. Thanks to its very high insulation value, it is the best insulation material in the world. Spray application of polyurethane foam is quick and effortless.

Technical features to grasp when choosing to buy a pu foam injection machine 1. Machine configuration: – Two metering pump system (10cc/vong – pump imported from Taiwan) – Material components A (poly),B (Iso) and controlled by inverter. – System of 02 hybrid motors 2.2 kw – used to pull the metering pump – 01 set of spray gun, which opens and closes the valve, automatically cleans after spraying with air and detergent. – Electrical control system (control cabinet + inverter (FRECON) + PLC (Mitsumi) + 7inch screen) – Pipeline system, material loading. – Mobile vehicle girder system + robotic arm. – Two containers for Poly and Iso . materials – PoLy chemical stirring pump system (substance A) in the tank (stirring motor + stirrer). – MC cleaning system (acetone) – cleaning gun after spraying. – Automatic feeding system by engine.

1.2. Technical features: – Output material injection pressure is 5 – 25kg/cm2 – Mixing ratio of components A, B : 1/1 to  2/1 (adjustable via inverter + PLC system). – Continuous flow of mixed mixture (foam) : (5 -10)kg/min – Mixing type spray pouring. – Spray mode : Free or dosing (automatic dose cutting) – Power consumption : 380v, – Air source : 350 liters/min. ( air compressor 7.5  Kw ), for the compression pump to charge and wash the gun.

Applications of PU foam injection machine

Pu Foam injection machine is applied and used in many cases such as: Construction of soundproof room –   With the characteristics of PU foam material, it provides excellent sound insulation. Therefore, when building soundproof rooms such as karaoke rooms, bars, workshops, factories, etc., there is a high noise working environment, if using a PU foam sprayer, it will create an effective soundproof barrier. Construction of insulation products –   PU foam injection machine with good thermal insulation properties is often used in the production of materials such as panels, insulation systems, etc.  Besides, the machine is also used in the production process of products requiring high degree of precision High insulation such as cold storage, refrigerator, cold room. These products require good insulation, so the sprayer is an indispensable equipment in this production. –  PU foam sprayer is also used to insulate cold storage of fishing vessels, etc., or to prevent rust for products with high corrosion such as prefabricated steel structure frames, extremely effective. With the safe properties for health, the environment and good heat resistance, the sprayer is being used very popularly on the market.
