Polyacrylamide is a flocculant widely used in water treatment, papermaking, mining and other fields. Proper use of polyacrylamide can improve water treatment effect and reduce cost.
This article will give you a detailed introduction about the Instructions and precautions for polyacrylamide.

一. Instructions for using of polyacrylamide
1. Preparation of solution: Add polyacrylamide to clean water in an appropriate proportion, stir evenly, and form a solution with an appropriate concentration after it is completely dissolved.
2. Adding method: Slowly add the prepared polyacrylamide solution into the water to be treated, and at the same time fully stir, so that the polyacrylamide can fully contact with the impurities in the water.
3. After the stirring is stopped, the flocculant will form flocs with the impurities in the water, which will be separated from the water by sedimentation or flotation.
2. Precautions for using of polyacrylamide
1. Avoid direct contact: Polyacrylamide is a slightly irritating chemical, and protective equipment should be worn during operation, and long-term contact should be avoided as much as possible.
2. Storage conditions: Store polyacrylamide in a cool and dry place, avoid direct sunlight, and prevent moisture.
3. Avoid contact with incompatible substances: polyacrylamide should not be mixed with strong oxidants, strong acids, strong alkalis, etc., so as not to cause dangerous reactions.
4. If any discomfort occurs during use, stop using it immediately and seek medical advice.
5. Pay attention to the dosage: the dosage of polyacrylamide will directly affect the water treatment effect. Too much dosage may lead to high concentration and increase the cost of water treatment; too little dosage may fail to achieve the ideal flocculation effect. Therefore, it should be tested according to the actual situation before use to ensure that the dosage is appropriate.
