Introduction to the Working Principle and Features of Polyurethane Spray Machines
Do you know that when we construct houses and buildings, the coating we typically use for insulation and waterproofing is called polyurethane, and the machine we use to apply it evenly by spraying is known as a polyurethane spray machine? How does a polyurethane spray machine work, and what are its key features? Let’s take a closer look.

High-Pressure Structure and Operating Principle of Airless Sprayers
With advances in science and technology, the coatings industry is evolving toward mechanization, automation, and continuous production. Traditional manual brushing and roller application can no longer meet the demands of modern industry. High-pressure airless sprayers, which offer high efficiency, minimal paint mist during operation, and superior coating quality, have been widely adopted across numerous sectors.

Application Status of Polyurethane Spray Machines
Polyurethane spray insulation is currently one of the highest‑performing insulation materials available worldwide. Rigid polyurethane spray foam boasts a light weight, low thermal conductivity, excellent heat resistance, good aging resistance, and ease of application. It adheres well to other composite building components and does not produce molten droplets when exposed to fire. In Europe and North America, it is widely used as an insulating material for roofs, walls, ceilings, floors, and doors and windows. In developed countries such as those in Europe and North America, approximately 49% of all building insulation consists of polyurethane spray foam, whereas in China, this figure remains below 10%.

Introduction to the Application Advantages of Polyurethane Spray Machines
Polyurethane spray machines and waterproof coating sprayers are essential components of the spraying industry. They offer a wide range of applications, with a single material providing thermal insulation, heat resistance, and waterproofing. As China’s building‑energy‑efficiency market has grown rapidly, polyurethane spray equipment has been extensively adopted in building insulation and waterproofing, securing a dominant market share. Polyurethane spraying comprises two main processes: direct application of primer and synthetic resin, and foamed polyurethane spraying. The primer‑and‑synthetic‑resin approach is primarily used for corrosion protection, wear resistance, air tightness, and thermal insulation. So what are the performance advantages of polyurethane spray machines? Let’s take a look.

The widespread application of polyurethane spray machines
When applying rigid polyurethane foam using a polyurethane spray machine, the nozzle should be kept at a consistent distance from the substrate to ensure uniform thickness of the insulation layer and to minimize material overspray during application. Based on practical experience with polyurethane spray equipment, the recommended nozzle‑to‑substrate spacing is 800 mm to 1500 mm. After spraying, a self‑inspection, leveling, and repair process should be carried out. As the inspection and repair phase represents the final step in the entire construction sequence, it must be approached with due diligence.

Causes of Slippage in Polyurethane Spray‑Machine Piping
Thanks to the sustainable development of the exterior wall insulation industry, we can increasingly see buildings insulated from the outside using polyurethane spray‑on equipment. As a widely adopted type of polyurethane spraying machine, the demand for high‑pressure polyurethane sprayers has been steadily declining. Below, we primarily discuss the causes of slippage within the piping of polyurethane spray‑on machines.
