Although photo treatment after alkaline etching is an auxiliary process, attention must be paid to the lifespan of the photo solution, the quality of the industrial floor photo, and production costs. To extend the lifespan of the photo solution, pre-lighting can be implemented. The concentration of the alkaline etching liquid is relatively high. Even after flowing water rinsing, the water on the workpiece surface is weakly alkaline. Consequently, the acid in the photo solution is neutralized quickly after use, losing its photo and dust-removing functions. Therefore, pre-treatment should be carried out before the waste photo solution on the industrial floor is officially turned off, followed by the entry into the formal extinguishing liquid for extinguishing.
This not only extends the lifespan of the luminescent solution but also reduces the cost of waste disposal.
Maintain Solution Purity to Prevent Contamination. To keep the luminescent solution clean, it must be dedicated to prevent the surface of the luminescent components from appearing due to the mixing of other metal ions in the replacement layer; the use of this solution must be suspended. When the luminescent solution is stopped, keep the lid on. Industrial floor luminescent liquids have a high concentration, especially nitric acid monoluminescent liquids are highly volatile. Covering the solution not only reduces evaporation but also prevents acid mist from polluting the environment. This should be done.
Industrial floor lighting components are alkaline, with the consumption of the luminous liquid primarily for neutralization. Therefore, when three luminous liquids enter the human body, the surface residual alkaline substances must be washed off with clean water.
