Embodiment 8
[0024] Embodiment 8 Cleaning comparison test of broad-spectrum high-efficiency cooling system cleaning agent of the present invention
[0025] Get the automobile cooling system cleaning agent 500g that above-mentioned any embodiment produces, after mixing and diluting with water 1: 10 (mass ratio), inject into cooling system; Start engine, after idling for 5 minutes, vehicle can run normally, and travels 1~2 hour , stop and drain the cooling system. Then fill the cooling system with clean water, start the engine and run it at idle speed for 5 minutes, then empty it. If the drain water is dirty, please rinse it with clean water until the drain water is clear.
[0026] In order to prove that cleaning agent of the present invention is better than conventional cleaning agent, select conventional inorganic acid (LX-VII cleaning agent, hydrochloric acid content 8%) type cleaning agent, organic acid (LX-IX cleaning agent, sulfamic acid content 89%) type cleaning Table 2 shows the co...
