Nonionic Polyacrylamide Powder

You can rest assured to buy Shuodi Nonionic Polyacrylamide Powder from our factory and we will offer you the best after-sale service and timely delivery. Qingdao Shuodi Environmental Protection Technology Co., Ltd. has been a Chinese manufacturer of non-ionic polyacrylamide powder for many years, non-ionic polyacrylamide powder, which is a linear polymer compound. It is easily soluble in water, and the appearance is white powder. It has a series of advantages such as good water solubility, fast dissolution speed, narrow molecular weight distribution, small actual dosage, and wide pH range (1-8). Non-ionic polyacrylamide powder is mainly used as a sewage treatment agent and is suitable for acidic suspensions. Non-ionic polyacrylamide powder uses its long molecular chain adsorption and bridging effect to flocculate and precipitate suspended particles to achieve the purpose of purifying water .

Product Description

Nonionic polyacrylamide powder is a high-purity, high-solubility, high-molecular-weight homopolymer formed from acrylamide, and has good water solubility. It can adsorb solid particles suspended in water, build bridges between particles, or cause particles to aggregate to form large flocs through charge neutralization. Therefore, nonionic polyacrylamide powder is used as a precipitating agent in many different mineral processing applications, mainly for flocculation, sedimentation and clarification of various industrial wastewater.

The main application of nonionic polyacrylamide powder

1. Coal mine washing

It can be used for centrifugal separation of coal washing tailings, used in the precipitation and filtration of coal powder and coal slime, and can improve the recovery rate of coal powder and the filtration rate.

 

2. Textile auxiliaries

When adding some other chemicals, it can be formulated into chemical size for textile sizing to improve adhesion, permeability and desizing performance, make fabrics antistatic, reduce sizing rate, and reduce sizing spots.

 

3. Sewage treatment 

When the sewage system is slightly acidic, it is more suitable to choose non-ionic series polyacrylamide, and use it together with inorganic flocculant polyaluminum chloride, aluminum sulfate, etc., and the effect in water treatment is the best.

 

4. Sand prevention and sand fixation

Dissolve non-ionic polyacrylamide to a concentration of 0.3% and add a cross-linking agent, and spray it on the desert to prevent wind and fix sand.

 

5. Chemical grouting agent

Mixing 9.5 parts of nonionic polyacrylamide with 0.5 parts of N-methylenebisacrylamide can be used as a chemical grouting agent for water blocking in dams, foundations, and tunnels.

 

6. Soil moisturizer

It is used as the basic raw material of soil moisturizing agent and various modified polyacrylamides. Plant grass and trees on hillsides, and sand-fixing and dust-proofing can act as a humectant.

How to use non-ionic polyacrylamide powder and precautions

1. When using, according to different sewage and different application processes, the optimal dosage should be determined through small-scale experiments to achieve the best effect. First, it should be prepared into a uniform solution with a certain concentration (0.1%) and then diluted into a dilute solution before use.

2. It is better to prepare the polymer flocculant aqueous solution in enamel, galvanized, aluminum or plastic barrels.

3. During the solution, care should be taken to add the product evenly and slowly and stir to avoid forming large lumps. The solution should be prepared at room temperature, and it can be accelerated into a solution by heating appropriately (<60°C). Excessive mechanical shearing for a long time should be avoided, so as not to reduce the use effect.

4. The solution is generally ready-to-use, try to avoid using it every other day, no more than three days at most.

5. Avoid spreading solid products on the ground to prevent the ground from becoming slippery after the product absorbs moisture.

Packaging and storage of nonionic polyacrylamide powder

The product is packaged in a 25kg plastic-lined woven bag or double-layered paper-plastic composite bag, or it can be packed according to customer requirements. When storing and transporting, pay attention to heat protection and moisture protection. Dry powder products will absorb moisture and agglomerate if left exposed for a long time. The effective storage period is 2 years.
