Embodiment 1
[0028] Such as figure 1 , figure 2 , image 3 and Figure 4 The monomer foaming furnace shown includes circulation fan, smoke exhaust fan, burner, combustion chamber, explosion-proof hole, combustion fan, air inlet, air exchange valve, temperature detector, heating air hole, control box, smoke exhaust pipe , Exhaust outlet, furnace body, furnace door, circulating air duct.
[0029] The control box is equipped with a power supply control and a program controller, and the temperature in the furnace is controlled by the program controller to reach the temperature and holding time required for product vulcanization and foaming in different periods.
[0030] Open the furnace door, put the rubber and plastic pipe material with a Φ of 65 mm and a wall thickness of 20 mm to be foamed on the material rack, enter the furnace cavity through the furnace door, and wait for foaming after closing the furnace door.
[0031] Start the power control and program controller, and set the proc...
Embodiment 2
[0035] The same foaming furnace and the same foaming process as in Example 1 were used, except that the rubber-plastic pipe material with a Φ of 50 mm and a wall thickness of 20 mm was to be foamed. When the temperature in the furnace cavity reaches 110°C, the burner and circulating fan stop working. After 8 minutes of heat preservation, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 115°C, the burner and circulating fan stop working and keep warm for 35 minutes. Finally, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 125°C, the burner and circulating fan stop working. After 12 minutes of heat preservation, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 135°C, the combustion The burner and circulation fan stop working. After 25 minutes of heat preservation, the burner and circulation fan continue to work. When the tempera...
Embodiment 3
[0038] The same foaming furnace and the same foaming process as in Example 1 were used, except that the rubber-plastic pipe material with a Φ of 45 mm and a wall thickness of 16 mm was to be foamed. When the temperature in the furnace cavity reaches 110°C, the burner and circulating fan stop working. After 5 minutes of heat preservation, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 115°C, the burner and circulating fan stop working and keep warm for 40 minutes. Finally, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 125°C, the burner and circulating fan stop working. After 10 minutes of heat preservation, the burner and circulating fan continue to work. When the temperature in the furnace cavity reaches 135°C, the The burner and circulation fan stop working. After 28 minutes of heat preservation, the burner and circulation fan continue to work. When the temperature in the...
