摘　　要：通过试验研究,本文着重说明了高纤维素型焊条的抗气孔性能、涂压性和电弧吹力及其影响因素。结论是:药皮保持一定的含水量和含结晶水的矿物质能够有效地防止气孔,低模数水玻璃能改善涂压性,药皮中保持一定的含水量和含结晶水的矿物质及燃点高的纤维素能增大电弧吹力。The gaspore sensitivity, extruding performance and arc spray force are studied in this paper by experiments. The results are the proper contents of the water and the minerals with the water of crystallization in the coating can effectively prevent the gas hole, the lower modulus of water glass can improve the extruding performance, the suitable contents of the water and the minerals with the water of crystallization and the higher kindling temperature cellulose in the coating can improve the arc spray force.
