Abstract
A method of testing penetration of a slurry through a mat facer includes the steps of placing the facer mat beneath a slurry test dispenser, storing slurry in a reservoir of the slurry test dispenser, dispensing slurry from the slurry test dispenser onto a first surface of the mat facer, allowing the slurry to harden, and observing the second surface of the mat facer for slurry penetration.
Claims20
A method of testing penetration of a slurry through a mat facer, the method comprising the steps of:
- placing the facer mat beneath a slurry test dispenser;
- storing the slurry in a reservoir of said slurry test dispenser;
- selectively dispensing the slurry from said slurry test dispenser onto a first surface of the mat facer;
- allowing the slurry to harden;
- and
- observing a second surface of the mat facer opposite of said first surface for slurry penetration.
A slurry test apparatus for testing the penetration of a slurry through a mat facer, comprising:
- a slurry test dispenser having a body defining a reservoir configured to store slurry, a bottom orifice of said body in fluid communication with said reservoir for selectively dispensing the slurry from said reservoir;
- a sample mat facer located beneath said bottom orifice and including a top surface configured to receive the slurry, and a bottom surface opposite said top surface;
- said bottom orifice being disposed a predetermined distance above said top surface so that the emitted slurry flows directly upon said sample mat facer.
A slurry test dispenser for testing slurry comprises:
- a generally cylindrical body defining a reservoir configured to store slurry, said body having a top opening for receiving the slurry;
- a bottom orifice in fluid communication with said reservoir and located opposite of said top opening for selectively dispensing the slurry;
- and
- at least one leg configured for supporting said cylindrical body above a substrate receiving the slurry.
