First you put the wash in the basket and push it inside, then tighten the door and tighten it. Use 30 minutes to heat the workpiece to 350 degrees and open the vacuum pump when the temperature reaches 340. It is important to observe whether the needle on the thermometer is gradually rising, and if there is no increase or speed, you need to check for leaks.
The temperature in the furnace is kept at 350 degrees for 90 to 120 minutes, and more than 80 percent of the experimental high polymer melt into the waste collection tank, which is cooled and then processed. The period can be increased or reduced according to the content of the high polymer. Then heat the oven to 480 degrees in 30 minutes.
In the furnace temperature of 500 degrees heat preservation after at least six hours, make the rest of the small amounts of polymer under the conditions of high temperature, vacuum, low oxygen, oxidative decomposition, this is the main stage can wash clean. During this time, the high polymer in the furnace will be decomposed into carbon dioxide and water. At this time, through the suction of the water ring vacuum pump, the carbon dioxide and water vapour generated in the furnace are processed by the water spray scrubber. As long as there is enough time, there will be no organic matter to be cleaned, and the process will be set at 7.5 or 8 hours, when the high polymer above is more.
Fourth steps to run after the procedure at the end of the whole, this furnace immediately with water and electricity meter electricity, only enter a state of natural cooling, without human intervention.
