Abstract
A sheet for forming a floor in a mine or for forming a road on permafrost. A method for making a sheet that is a closed foam celled sheet. A system for making a sheet.
Claims16
A sheet comprising:
- a top surface, a bottom surface, a first side and a second side, a closed foam cells core between the top surface and the bottom surface in the first side and the second side, the core supporting at least 1000 psi of compressive force, the top surface being at least 2 feet wide by 4 feet long, the sheet weighing less than 40 lbs. and is one continuous sheet.
A sheet comprising:
- a top surface, a bottom surface, a first side and a second side, a closed foam cells core between the top surface and the bottom surface in the first side and the second side, the core supporting at least 1000 psi of compressive force, the top surface being at least 40 yards long and 6 feet wide and being one continuous piece.
A method of producing a sheet comprising the steps of:
- feeding under a pressure of at least 100 psi a first fluid material into a first input port of a Y junction;
- feeding under a pressure of at least 100 psi a second fluid material into a second input port of the Y junction;
- directing the first fluid material and the second fluid material together out and output port of the Y junction into a conduit;
- mixing the first and second fluid materials in the conduit into a mixture as the first and second fluid materials flow through the conduit to a spray bar;
- and
- spraying the mixture out nozzles in the spray bar to form a sheet with a closed foam celled core that supports at least 1000 psi of compressive force.

A system for making a sheet for a floor with a first component and a second component comprising:
- a pump having a first portion which receives the first component, a second portion which receives the second component, a first pump line and a second pump line;
- a Y junction having a first input port to which the first pump line is fluidically connected and to which the pump pumps the first component, and a second input port to which the second pump line is fluidically connected and to which the pump pumps the second component, under the action of the pump, the first component and the second component are combined in the Y junction and flow out of an output port of the Y junction to a first end of a conduit, that is fluidically connected to the output port of the Y junction;
- disposed in the conduit, in series, are positioned a plurality of static mixers that cause the first component and the second component to be mixed together into a mixture as the first component and the second component flow through the mixers in the conduit under the action of the pump;
- and
- a spray bar fluidically connected to a second end of the conduit, the spray bar has a plurality of nozzles, disposed in the spray bar in front of each nozzle, is positioned another static mixer to ensure the first component and the second component are fully mixed together.
