In the process of production and use of concrete admixtures, sodium metabisulfite needs to be added as raw material in some cases. However, sodium metabisulfite releases sulfur dioxide when it meets water, causing the water reducer to produce a pungent odor. This has a certain impact on the production environment and the comfort of workers. So, is there a way to adjust the smell of water reducer?
The answer is yes. First, we can choose to use food grade sodium metabisulfite. Compared to industrial grade products, food grade sodium metabisulfite releases less sulfur dioxide when it meets water, so the odor is relatively light. This can reduce the discomfort of the production environment and workers.
In addition, the problem can be solved by adding the right amount of sodium hydroxide (NaOH). Sodium hydroxide reacts with sulfur dioxide to neutralize its pungent odor. Adding an appropriate amount of sodium hydroxide can effectively reduce the odor of water reducer and make it more acceptable.
It should be noted that the amount of additives should be controlled when adjusting the odor of water reducer to avoid adverse effects on product performance. At the same time, when using sodium hydroxide should pay attention to safety, avoid contact with the skin and inhalation of its dust.
To sum up, by choosing food grade sodium metabisulfite and adding sodium hydroxide, we can effectively adjust the odor of water reducer and improve the production environment and worker comfort. In actual operation, it is recommended to test and adjust according to the specific situation to obtain the best results.
