The stove is suitable to clean the sets, spinneret and filter core which are used in the producing of terylene, Chinlon and polypropylene in chemical fiber industry. It can also be used to clean the die in plastics extrusion industry.
Based on the high polymer characters such as melting around 300℃, fissioning and coking above 300℃, and oxidizing above 400℃ with a little air, the work pieces adhered with high polymer dirt, firstly, should be heated up to 300℃ to melt these high polymers and make them drip to the collector below the hearth. And then, have the remainder polymer sufficiently oxygenated by heating the stove up to 400-500℃ and turn on the vacuum pump to absorb a little fresh air at the same time. After sprayed by the water, the resultant carbon dioxide will be ejected out together with the water by water-circle vacuum pump.
These stoves are all made of stainless steel electrical heating tube heated in the vacuum hearth, and all the sealing parts apply high temperature-resistant seal rings. As a result, they are provided with many advantages such as low heat-up power, high thermal efficiency, fast heating up, even temperature distribution, convenience in maintenance, . And they have also overcomed the shortcomings of bad homogeneity of the temperature in the stove and poor cleaning effects in some location, which result from the water cooling.
In addition, they can do the cleaning job automatically by inputting the program into the temperature controller without manual operation. They also have the features of exceeding temperature, open phase, water break-off and warning ability to low water pressure. -
