Secondary containment panels and process for making and installing same
A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. A system for coating secondary containment panels. An apparatus for spraying a coating on a secondary containment panels. The apparatus may be computer controlled and operate automatically to coat the surface of the panel.
1. A system comprising:
a computer controlled robotic sprayer housed within a structure;
a coating supply source coupled to the sprayer; wherein the coating supply source provides a coating comprising polyurea to the robotic sprayer;
wherein the robotic sprayer comprises a nozzle, and wherein said nozzle points in a downward position
wherein the robotic sprayer sprays the coating in a reciprocating pattern;
a substrate located below the robotic sprayer, and wherein said structure comprises an environmentally controlled structure, and wherein said nozzle points toward said substrate;
wherein said robotic sprayer is coupled to a self-propelled computer controlled sprayer carriage, wherein the sprayer carriage is moveable longitudinally;
wherein the sprayer carriage extends over a width of a substrate located below said robotic sprayer, wherein the sprayer traverses laterally across the width of the substrate, and wherein the sprayer travels longitudinally relative to the substrate
wherein the sprayer carriage comprises wheels to traverse above said substrate.
2. The system of claim 1 wherein said substrate is stationary and flat beneath the robotic sprayer.
3. The system of claim 1 wherein when the computer controlled robotic sprayer is activated, the sprayer sprays a determined quantity of coating across the width of the substrate as the robotic sprayer traverses laterally across the width of the substrate, and wherein the substrate comprises a geotextile fabric.
