I have been working for over two years on a continuous mixer/sprayer solution for chemically bonded phosphate ceramics. Whether you are using a
potassium phosphate or a magnesium phosphate is immaterial however, my lab guy gets much better flexural numbers from the Mag Phos formulation.
Compression numbers are about 14k psi. Flex numbers about 2k psi. I am about six months away from my latest prototype as I had to redesign the water
injector system to a much greater precision. I have also had to redesign the mix chamber to create a much higher sheer/pressure sustaining sleeve as
the formulation is very thick and dry until 80% of the travel through the high sheer portion of the chamber.
Once complete, you should be able to coat a maximum 50 sq ft per min at between 1/4" to 3/8" thickness.
Clean-up is a cinch as all mixing elements are made of plastic...if the material sets up, it de-laminates easily with finger pressure.
Working time of sprayed material is dependent upon surface temperature but tends to be about 3 minutes at room temperature.
I am willing to chat directly to UFOTECH by e-mail if you can arrange it with the administrator.
