Appl. No.:

17/089858

Inventors:

Jacob T. Weil - Toledo OH, US
Thomas J. Quagliotto - Toledo OH, US
Kyle S. Strait - Holland MI, US

Eric Calhoun - Wyandotte MI, US

International Classification:

A47L 11/40
A47L 11/30
B01D 19/02

Abstract:

A floor cleaning machine is provided. The floor cleaning machine includes a cleaning head configured for cleaning a floor surface with a cleaning solution. A collection mechanism is configured to collect used cleaning solution following use by the cleaning head. A conduit fluidly connects the collection mechanism with a recovery tank. The conduit is configured to convey a flow of the used cleaning solution from the collection mechanism to the recovery tank. A defoaming system is positioned proximate the recovery tank and includes a solid chemical defoaming form. The solid chemical defoaming form is configured for dissolution within the flow of the used cleaning solution. The flow of the used cleaning solution is directed over the solid chemical defoaming form and into the recovery tank.

International Classification:

A47L 11/28

Abstract:

A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.

Abstract:

Base coats, methods of using base coats, and methods of producing base coats are provided. In an exemplary embodiment, a method of producing a base coat includes forming a CPO intermediate and a color intermediate. The CPO intermediate includes a chlorinated polyolefin at from about 5 to about 20 weight percent, based on a total weight of the CPO intermediate, as well as a CPO solvent. The color intermediate includes a color imparting additive and a color solvent that is different than the CPO solvent. The CPO intermediate and the color intermediate are combined to form the base coat, where the base coat includes from about 1 to about 3 weight percent chlorinated polyolefin and from about 5 to about 30 weight percent solids, based on a total weight of the base coat.
