How many square meters of foam can be
sprayed on a ton of polyurethane raw materials?
Thank you for your invitation. I'm at the
construction site. I just got off the hanging
basket.
Usually we call the volume change of polyurethane from raw material to foam
as the volume of output.
The output is affected by many factors. The most important factor is the
density of the foam, which is determined by the formula of the raw materials.
At the same time, the mixing efficiency (pressure, temperature, mixing
accuracy) of the polyurethane spraying machine, ambient temperature, substrate
temperature and other factors will also affect the density of the final
product.
Let's take the most commonly used 30 kg/m3 foam in building thermal insulation
spraying as an example. At standard ambient temperature
A ton of raw materials such as polyurethane can produce 18-22 cubic meters of
foam. If the spray thickness is 2
Then a ton of polyurethane foam can emit 900-1100 square meters of foam. If the
spray thickness is
5 cm, then a ton of polyurethane foam can emit 360-440 square meters of foam. If
the spray thickness is
10 cm, then a ton of polyurethane foam can emit 180-220 square meters of foam.
