polyurethane foam spray machine

Polyurethane foam spraying machine features:

1.Excellent thermal insulation performance: The modified SPF hard foam micropores are sealed with a low thermal conductivity foaming agent gas, and its thermal conductivity is lower than 0.024W/(mK). The round shape is superior to the traditional thermal insulation material. It is widely used in cold storage, refrigerator ultra-low temperature gas storage tanks and space vehicles.

2, excellent water resistance: modified SPF rigid foam continuous dense skin and nearly 100% high-strength interconnected closed cells, with project impermeability and good water vapor permeability resistance, using on-site direct spraying technology, can be in the building The roof forms a seamless waterproof layer with no seams, which is unparalleled compared to other waterproof materials in the construction of shaped roofs and special-shaped structural parts.

3, super wind resistance: modified SPF hard foam has excellent self-adhesive properties, has strong self-adhesive properties for metal, concrete, masonry, wood, glass, fiber, as the roof and exterior wall The water insulation layer is extremely resistant to wind.

4, good flame retardant properties: modified SPF rigid foam is a thermosetting insulation material, formed a conversation on the surface of the fire, not melting, no melted dripping, will not form a secondary fire source. The long-resistance B1 high-resistance polyurethane rigid foam developed by Jiangsu Jiujiu Co., Ltd. meets the fire safety requirements of high-rise buildings, and has passed the weathering, freeze-thaw and fireproof tests conducted by the Ministry of Construction's polyurethane energy-saving application promotion working group.

5. Ideal strength: The strength of the modified SPF rigid foam depends on his raw materials, formulation, density, structure and molding process. When other factors are relatively constant, the density determines the strength. The SPF hard foam density is greater than 55kg/ The m3's upper roof has a good compressive strength of more than 400kpa.

6. Low comprehensive cost and short construction period: Although the modified SPF hard foam is higher than other single waterproof or thermal insulation materials, it has multiple functions such as waterproof, heat preservation and flame retardant, which makes the overall roof cost lower than the traditional one. The roofing cost of building materials. The SPF hard foam has a small specific gravity and is of great significance to the structural cost of large-span and thin-shell roofing. SPF hard foam waterproof insulation layer can be sprayed on site, once formed, and construction is fast.
