Abstract
A synthetic sponge having a high density is rinsed while changing the hydrostatic pressure of rinsing solution in pore spaces of the sponge to remove chemical residue and particulate matter more completely. The hydrostatic pressure can be changed by varying fluid supply pressure or varying centrifugal force. A rinsing apparatus includes a rotatable container and a fluid supply for supplying rinsing solution to sponge material in the container.
Claims5
An apparatus for rinsing synthetic sponge material, the synthetic sponge material being formed though a process which leaves residue or particulate matter in pore spaces of the synthetic sponge material, said apparatus comprising
- a base;
- a container mounted on said base and having a perforated core centrally disposed therein, said container including a wall defining an interior between said perforated core and said wall for receiving the synthetic sponge material;
- a rinsing solution conduit coupled with said perforated core for supplying rinsing solution through said perforated core into said interior of said container;
- and
- means for changing hydrostatic pressure of the rinsing solution in the pore spaces of the synthetic sponge material disposed in said container, whereby the residue or particulate matter is removed from the pore spaces.
