PolyDADMAC, as a cationic polymer, can effectively adsorb negatively charged particles, impurities and suspended matter in water during water treatment, so it is widely used in ultrapure water treatment.

PolyDADMAC, as a cationic polymer chemical additive, has been widely used in the petroleum industry, especially in drilling fluid treatment and emulsion breaker, by virtue of its good performance.

Poly(dimethyldiallylammonium chloride) has become an important tool for solving water pollution and ensuring the safety of drinking water by improving the efficiency of water treatment and water quality through flocculation.

As a cationic polymer flocculant, poly(dimethyldiallylammonium chloride) has shown potential for a wide range of applications in mining and mineral processing. Its good flocculation effect and environmentally friendly properties make it an important tool for mining enterprises to increase resource recovery, improve tailings treatment and reduce costs.

In this paper, we will discuss the role of PDADMAC in textile dyeing and finishing auxiliaries, especially its performance advantages as a non-formaldehyde color fixing agent, and how to improve the dyeing fastness of fabrics through the film-forming effect.

Poly(dimethyldiallylammonium chloride), as a kind of polymer chemical agent, is widely used in the field of sludge dewatering due to its good flocculation properties.

Cationic coagulants have significant application value in the field of sludge treatment, and their efficient flocculation performance, wide applicability and environmental protection characteristics make them play an important role in municipal sludge, industrial sludge and paper sludge treatment.

Cationic polyacrylamide (CPAM) is a polymer coagulant widely used in the field of wastewater treatment. Mainly including municipal sewage treatment and industrial wastewater treatment.

The wide application of water treatment chemicals in various fields not only improves the efficiency and effectiveness of water treatment, but also plays an important role in protecting the environment and resources.

Sludge dewatering agent plays a key role in the sewage treatment process, mainly promoting the dewatering of sludge, improving dewatering efficiency, reducing sludge volume.

Cationic functional monomers are a class of polymer monomers with cationic groups, which are able to introduce positive charges during polymerization, thus giving polymers special physicochemical properties.

The main uses of cationic polyacrylamide include: sludge dewatering, flocculation, sedimentation, filtration, controlling taste and odor, removing algae and other microorganisms from water, preventing the formation of scale and other sediments in pipelines and other equipment, etc.

Cationic polyacrylamide (PAM) is a polymer with a large amount of positive charges. Due to the strong adsorption of positively charged groups on its molecular chain with negatively charged particles and colloids, it achieves flocculation and sedimentation effects.

The main uses of cationic polyacrylamide include: sludge dewatering, flocculation, sedimentation, filtration, controlling taste and odor, removing algae and other microorganisms from water, etc.

The method and precautions for the use of polyquaternary ammonium salts may vary according to the specific application and product, and the concentration of polyquaternary ammonium salts can be adjusted according to the specific needs of the application and the appropriate dosage can be obtained through experimentation.

High-efficiency sludge dehydrating agent is a high-performance polymer whose main function is to improve the sludge structure and dewatering effect, thus reducing the volume of sludge.

Polyquaterniums are cationic (positively charged) polymers, polyquaternium (acronym Polyquat), which help to enhance the shine and softness of hair while simultaneously reducing frizz, breakage and split ends.

Given that oily wastewater has the characteristics of being difficult to degrade and easy to emulsify compared to other general polluted water sources, conventional treatment processes cannot achieve the expected results. This article briefly introduces the coagulation ultrafiltration treatment process for oily wastewater.

Polymer coagulants have strong adsorption properties and aggregation capacity, and metal salt coagulants are able to treat large amounts of wastewater quickly and at low cost.
