Can hydrochloric acid be used for tile laying in dry scrubbers and similar structures?

I wonder what you’re thinking about all day long? Why was hydrochloric acid considered? o After the tiles are laid, acidification is necessary; essentially, the mortar needs to be further solidified using acid. This question should be answered by the manufacturer of the clay. Since the dry absorption tower ultimately comes into contact with sulfuric acid, acidifying it with sulfuric acid is the best approach. Using hydrochloric acid poses many problems; firstly, chlorides are highly soluble, and it is uncertain whether the slurry can be solidified. Secondly, chloride ions will eventually be displaced by sulfate ions; not only does this damage the structure of the cement, but chloride ions also cause corrosion to the metal components in the system (most stainless steels are not resistant to chloride-induced corrosion). So, hydrochloric acid is out of the question. For acidification, it is best to apply an isopropyl alcohol solution containing 20% sulfuric acid to the brick joints; an aqueous solution of 20% sulfuric acid is a good alternative. In accordance with the requirements of the clay manufacturer.
Currently, only hydrochloric acid is in stock; sulfuric acid is not available (it will take at least January to get it). A portion of the bricks has already been laid, and acidification is better for the construction quality. I asked some masonry factories, and they said it’s okay; they have used it before and haven’t encountered any serious problems. Of course, it would be perfect if the second floor could be realized, but reality is just so harsh!
There’s no need to acidify it right away; we can do that after the construction is complete. It’s better to wait. If you really feel bad about it, just buy some bottled sulfuric acid for laboratory use as a makeshift solution.
Anticorrosion experts say it’s better to do it early. There was no sulfuric acid on site; why wasn’t it prepared in advance? There are no excuses, only reasons. :For reference, the KPIs for P online are as follows; experts are welcome to provide their feedback: (5) Acidification treatment: 20%–40% sulfuric acid, 15%–20% hydrochloric acid, or 15%–30% nitric acid can be used for this purpose, with the treatment being applied 3–4 times. Apply the treatment evenly every 8 hours or more, sweeping away the white crystalline powder that has precipitated in each application.
