Thermal annealing is performed using an annealing oven with [N.sub.2]/[H.sub.2] and low pressure of 5mbar.
After that part is pulled and cooled, it goes into an annealing oven for seven hours to remove the residual stresses.
At 450C during the day and 370C overnight, the annealing oven helps to take the stress out of cooling glass.
The new plant will utilize technologically advanced environmental safeguards, including new low emissions manufacturing techniques like water-based paints and low nitrous oxide annealing oven burners.

The vials were washed by exposing them to the following solutions or groups of solutions for a period of 30 min each: (a) methanol--water (9:1 by volume) saturated with EDTA; (b) acetonitrile--water (3:1 by volume) containing 1 g/L DTT; (c) 0.5 mol/L NaOH followed by a distilled water wash, then 1 mol/L HCl followed by a distilled water wash; (d) distilled water followed by heating for 18 h in an annealing oven at 500 [degrees]C; (e) 0.1 mol/L nitric acid followed by distilled water wash; (fl 1 mol/L HCl followed by a distilled water wash.
A continuous slab of melted glass flows out of the bottom of the two-story equipment and onto a conveyor system that feeds it into a 600 [degrees] C annealing oven. The tank-conveyor-oven equipment is about 50 m long.
To erase the injection molding induced thermal and mechanical histories, the samples were annealed in an oven at 117 [degrees] C (this annealing oven was measured to have a stability of [+ or -]3 [degrees] C during any given experiment).
When he's finished, Du Grenier removes the shell from the pipe and places it in an annealing oven. The temperature in the oven drops slowly, allowing the glass to cool, the without breaking.
The blow-molded bottle is removed by a takeout arm and set upon a conveyor that delivers it to an annealing oven. Here the bottle is heated and cooled during a 45-minute to 1-hour interval to remove the stresses that develop because the glass cools unevenly, particularly the threaded areas where it is not of uniform thickness, explained O'Donnell.
So shielded from the heat of the finished piece of art work he or she carries it over to one of a bank of annealing ovens, informally referred to as "hot boxes." There to prevent stress and breakage, the piece will gradually cool down at a rate of 24 hours per one inch of thickness.
Tritan's lower stress levels eliminate the need for an additional annealing step after molding (requiring expensive annealing ovens), thereby reducing energy use and overall processing time, lowering costs, and increasing production rates.
