Sodium formaldehyde sulfoxylate 99% is white block or crystalline powder, and the melting point is 64-68 °C. It is tasteless or slightly leek smell. Sodium formaldehyde sulfoxylate 99% is soluble in water and slightly soluble in alcohol. It is stable at room temperature, and has strong reducibility and bleaching effect at high temperature.

1. Determine the purpose: Calculate the required amount of sodium formaldehyde bisulfite according to specific needs. Under normal circumstances, the amount of formaldehyde sodium bisulfite used is 1% -3% of the total amount of the substance.
2. Dissolution: Mix sodium formaldehyde bisulfite with an appropriate amount of water and stir thoroughly to completely dissolve it. During the dissolution process, attention should be paid to controlling the water temperature to avoid being too high or too low, so as not to affect the effectiveness of formaldehyde sodium bisulfite.
3. Addition: Add the dissolved formaldehyde sodium bisulfite solution to the substance to be treated and stir evenly. During the addition process, the addition speed should be adjusted according to the actual situation to avoid being too fast or too slow, and to ensure that sodium formaldehyde bisulfite produces the best effect.
4. Observing reactions: closely observe changes in substances, such as color, odor, etc. If any abnormal situation is found, it should be stopped immediately and corresponding measures should be taken.

Sodium formaldehyde sulfoxylate 99% needs to be stored in a dry sealed environment. Packaging specification is 50KG / barrel.

Sodium formaldehyde sulfoxylate have strong reducibility. During use, contact with oxidants, flammable and explosive substances, etc. should be avoided as much as possible. Avoid direct contact with skin, eyes, etc. In case of accidental contact, rinse immediately with plenty of water. Avoid contact with metals.
