I would like to ask about the ratio of first-class products to qualified products.
Thread Content
For a certain product, one ton of high-quality hydrochloric acid is used in the reaction process, and half a ton of hydrochloric acid is used for pickling after the reaction is complete. What is produced in this way is first-class product. The two batches of pickled hydrochloric acid are combined to reach one ton for reuse, thereby producing qualified products. Continue to gather enough acid-washing hydrochloric acid to produce qualified products, thus yielding qualified goods; assuming this cycle repeats indefinitely, what would be the approximate ratio between first-class products and qualified products? How was it calculated? Thank you.
【And two batches of pickled hydrochloric acid are combined to reach one ton for reuse, thereby producing qualified products.】 】It is estimated that the effective amount of hydrochloric acid in the pickling solution is insufficient.
It’s because of impurities; otherwise, why would acid washing be necessary? I’m asking about the ratio between the two, boss
