Production of foamed sulfur compositions |
摘要 |
Sulfur-based foams are produced by heating to liquid state a sulfur formulation containing a minor amount of a gas-producing component in a first (molten) zone; passing the mixture maintained in liquid form to a second (mixing) zone where it is mixed with a foaming agent which in combination with the gas-produced compound releases gas, and the gas-containing mixture is passed from the second zone for use as a cellular construction material. Apparatus for carrying out the process is provided.
