Abstract: An apparatus, system, and method for recycling glass fiber waste, particularly glass fiber embedded within a binder material. The system includes a kiln, a char separator, and a multi-stage molten salt bath having a temperature gradient. Glass fiber waste is provided to the kiln which converts the waste into glass fibers and char. At least some of the char is then separated from the glass fibers in the char separator. The glass fibers, and any remaining char, are then placed in the molten salt bath at the point having the lowest temperature. The glass fibers are then moved to the higher temperature areas within the molten salt bath. As the glass fibers pass from the low temperature to the high temperature, any remaining char is consumed, and the glass fibers are reconditioned via ionic exchange for further use. The glass fibers are then cooled for reuse.

Abstract: An apparatus and a method for continuously manufacturing tempered glass are provided. The tempered glass is continuously manufactured by transferring the raw glass in one direction, spraying a boiled potassium nitrate solution to the raw glass to reinforce the raw glass, and recovering and reusing the potassium nitrate solution from the raw glass. This invention can reduce the time to manufacture tempered glass since you can manufacture tempered glass consecutively, and the cost of purchasing potassium nitrate solutions can be reduced, which has an economic advantage. Since the raw glass is preheated, strengthened and annealed by divided sections of preheating, strengthening and annealing section in one furnace, it is less likely that impurities will be attached to the raw glass due to low external exposure during each process movement, thus preventing deterioration of quality.
