TECHTONGDA High Pressure Polyurethane Foam Spray Machine Foam Injection Pump Coating Machine for Spraying and Pouring 3.5kW 220V

【Application】This polyurethane foam spray machine is primarily used for producing semi-rigid polyurethane products, offering both spraying and pouring functions. It is a versatile machine suitable for various applications, including highway filling, roof insulation, exterior wall insulation, cold storage insulation, yacht preservation, corrosion protection for steel structures, and waterproofing sports stadium floors.
【Principle】The foam injection pump comprises two distinct material boxes (left and right). Two differing liquids are fed into two ring piston metering pumps from these boxes. A motor powers both pumps via a gearbox. The liquids are then dispensed to the nozzle in preset proportions. Compressed air is introduced into the nozzle, where it mixes with the liquids and is sprayed onto the desired area, enabling efficient foam field construction. The volume of each compartment is 8gal/30L and can hold 66lbs/30kg.
【Constant Mixing】Thanks to the implementation of low-speed, high-precision metering pumps. These materials are accurately measured and blended using high-precision metering pumps, ensuring a precise 1:1 ratio and consistent performance. Despite fluctuations in material temperature, pressure, and viscosity, our low-speed pumps maintain a constant mixing ratio. With a maximum gear pump flow of 6KG/Min.
【User-Friendly Spray Gun】 The spray gun, complete with an extended pipeline length of 314.96 inches, has been engineered for exceptional user-friendliness. It produces a fine spray mist and uniform foaming, enabling precise and consistent application for optimal results. In addition, the gun is washable, easy to clean.
【Note】It is crucial to install proper ventilation equipment in the working area to ensure a safe and healthy environment during operation. This precautionary measure will help maintain normal equipment functionality and protect the well-being of the operators.

FAQ:

Q: Why to use polyurethane foam?

A: Applications for Polyurethane: In addition, rigid polyurethane foam insulates boats from noise and temperature extremes, provides abrasion and tear resistance, and increases load-bearing capacity all while adding minimal weight. Thermoplastic polyurethane is also great for use in the maritime industry.

Q: What can polyurethane be used for?

A: Polyurethane is used to coat wood floors to provide a layer of protection against scratches and scuffs.This is an extremely durable wood finish that’s simple to use, which has made it increasingly popular.

Q: Is polyurethane foam insulation flammable?

A: Spray Polyurethane Foam Insulation. Nothing beats spray polyurethane foam. Although a fast and economical way to insulate, spray polyurethane foam (SPF), like most other organic materials, is combustible. SPFs will, when ignited, burn rapidly and produce intense heat, dense smoke and gases which are irritating, flammable and/or toxic.

Q: What does polyurethane foam mean?

A: Polyurethane foam is a synthetic polymer that contains urethane radicals. Polyurethane foam is used to provide insulation and protection of material against external sources that propagate corrosion.
