Polydadmac For Wastewater

40% PolyDADMAC liquid  (Poly(dimethylamino)diallyl ammonium chloride) is a commonly used cationic polymer and its molecular weight(polydadmac synthesis) can be adjusted according to the specific product requirement. 

Generally speaking, the molecular weight range of wastewater PolyDADMAC is roughly from several thousand to several hundred thousand. The molecular weight specific of wastewater PolyDADMAC 

product can be adjusted and controlled through different processes and synthetic methods. 

In industrial production, different polymerization reaction conditions, initiators and catalysts can be used to control the molecular weight. 

By adjusting factors such as the reaction time, temperature and the ratio of reactants and solvents, PolyDADMAC wastwater use with different molecular weight ranges can be obtained. 

In practical applications,  wastewater PolyDADMAC synthesis with different molecular weights has different characteristics and uses. PolyDADMAC wastewater use with lower molecular weight is often used in water treatment agents, treatment agents for paper and textiles, softeners, etc.

PolyDADMAC wastewater use with higher molecular weight is widely used in the treatment of colloidal suspensions, sugar chemistry, medicine and other fields.

40%polydadmac liquid is the highest content and 40% polydadmac liquid is always be packed by drum or IBC.

Wastewater polydadmac is usually be used for wastewater and sewage treatment,it has stable performance and shelf time is 24Months. 

When choosing a 40% polydadmac liquid product, the molecular weight is one of the core indicators. It directly affects the product's flocculation ability, adsorption performance, solubility, film-forming property, and the intensity of interaction with other substances. 

It is necessary to match the performance characteristics corresponding to the molecular weight according to the core requirements of specific application scenarios (such as flocculation efficiency, penetration ability, compatibility, etc.). 

The following are the specific selection ideas: The molecular weight of 40% polydadmac liquid (usually in the range of several thousand to over 2,000,000) affects its functions through the length of the molecular chain: 

High molecular weight (generally > 500,000 Da): The molecular chain is long, with strong inter - chain entanglement ability. The "bridging effect" with particles / substrates is significant, resulting in strong flocculation and agglomeration capabilities. However, the solubility of 40% polydadmac liquid is poor (especially at high concentrations), the penetration speed is slow, and it is easily affected by salinity / temperature (in a high - salt environment, the chain may curl up due to charge shielding). 

Medium molecular weight (100,000-500,000 Da): It balances a certain chain length (bridging ability) and solubility, has a wider range of applicability, and performs better in scenarios where a balance between flocculation / adsorption and dispersion / penetration is required. 

 Low molecular weight (< 100,000 Da, even several thousand Da): The molecular chain is short, with excellent solubility (easily soluble in water or high-salt solutions), a fast penetration speed, and the charge density is relatively easier to exert (small molecules can more easily come into contact with the substrate surface). 

However, its bridging ability is weak, and the flocculation effect is poor. It is more suitable for scenarios such as "surface modification", "dispersion", and "solubilization".
