1. Animal oil blocking: if it is oil, it is recommended to use boiled water, of course, if there is concentrated sulfuric acid, the effect is better. If there is something blocking, you can use professional cleaning tools. 2、水泥堵：35%的盐酸，里面加少量一点面粉，起缓蚀剂的作用，有乌洛托品最好。可以减轻对钢铁的腐蚀。 2. Cement block: 35% hydrochloric acid, with a little flour in it to act as corrosion inhibitor. Urotropine is the best. It can reduce the corrosion of steel. 3、选用一根2米长的弹簧钢丝管道疏通工具,在其头上1-2公分处作一10-20度的弯曲,在下水道的进出口处来回疏通,并用水配合冲洗。 3. Select a 2-meter-long spring steel wire pipe dredging tool, make a 10-20 degree bend at 1-2cm above its head, dredge back and forth at the inlet and outlet of the sewer, and wash with water. |
