The reaction system has an obvious thermal effect. The thermal analysis of the components of the material has confirmed that this is due to the violent thermal decomposition of the components. Based on the extraction rate, product characteristics and extraction mechanism of the material, a sub-super

The manufacturer of the door fan sealing line rotation line believes that the edge -sealing line can realize the rotation and transportation of the long board or short board sealing plate, and it can also achieve the rotation and transportation of the edge of the irregular board. The edge of the boa
