A high-pressure cell is designed to test the sealing capability of tire sealant. The cell primarily consists of a glass cylinder, a circular piece of tire cut from the tread area, and provisions for mounting nails of various sizes.
- Requires only a small amount of sealant for testing
- Apparatus is easy to use
- Instant testing of tire sealant efficacy possible under the same conditions as an inflated tire
- Measurement of loss of pressure inversely correlated with the sealing capability of the sealant
- Vessel made of sheet metal or from a material such as hard plastic or toughened glass
- A jacketed vessel for controlling the test temperature
The high-pressure cell consists of a cylindrical glass tube, with one end sealed by a circular piece cut from a puncture-free tire. The other end of the tube is closed with a metal lid that includes separate inlets for air, sealant, and a pressure gauge, which features a safety valve. Beneath the pressure cell, there is an assembly with six slots for mounting nails of different sizes. The cylinder is made up of borosilicate glass which can sustain pressure up to 5 bar. The rest of the body of the apparatus is made up of mild steel.
An apparatus has been set up and tested and invention is at the stage of process qualification through test and demonstration. A method for testing the efficacy of the tire sealant has also been given. The patent has been granted and the technology is ready for licensing.
