Formula of efficient silicon-boron system impregnant as well as preparation and application processes of efficient silicon-boron system impregnant
The invention discloses a silicon-boron system impregnant, which is a solution prepared by blending 0.001%-10% of a silicon-based substance, 0.001%-10% of a boron-based substance, less than or equal to 10% of an auxiliary agent and 80%-99% of water according to a certain proportion. The auxiliary agent is a thickening agent, and the use amount of the thickening agent is adjusted according to actual requirements, so that the viscosity of the impregnant is controlled to be 0.01-10 Pa.s. The impregnant is organized and actively enters pores in the anode in a mode of first negative pressure and then positive pressure, is dried at a low temperature, and forms a compact silicon-boron anti-oxidation film on the inner cavity wall of an anode carbon block in a high-temperature environment during electrolysis, and has certain bonding strength, the silicon-based substance in the impregnant enhances the oxidation resistance of the carbon anode by improving the adhesion of a boron oxide film and the carbon anode, invalid oxidation in pore channels of the anode carbon block can be effectively prevented, the air reactivity is reduced, and a silicon-boron-carbon system forms a stable net-shaped structure in pores of the anode carbon block, so that slag falling is effectively prevented.
本发明公开了一种硅硼体系浸渍剂，是由0.001%‑10%的硅系物、0.001%‑10%的硼系物以及不大于10%的助剂和80%—99%的水，按照一定比例调和而成的溶液。助剂为增稠剂，根据实际要求调整增稠剂用量使浸渍剂的粘度控制在0.01‑10 Pa·s。通过先负压后正压的方式使浸渍剂有组织主动地进入阳极内部孔隙，在低温下干燥，在电解时的高温环境下，浸渍剂在阳极炭块内腔壁上形成致密的硅硼抗氧化薄膜，并具有一定的粘结强度，浸渍剂中的硅系物通过改善氧化硼薄膜与炭阳极的粘附性来增强其抗氧化性，能够有效防止阳极炭块孔隙通道内无效氧化，降低空气反应性，硅硼碳体系在阳极炭块孔隙内形成稳定的网状结构，从而有效防止掉渣。
