Paper Printing and Dyeing

Paper Industry

Xinqi Polymer offers a complete range of water-soluble polymers specifically designed to address various challenges occurring during the wet-end stages of the papermaking process:

► Paper Retention Aid
► Sludge Dewatering
► Dispersant Agent

Xinqi Polymer aims to help customers optimize costs and improve machine efficiency while enhancing the appearance and performance of printed paper and paperboard. We are committed to providing environmentally friendly and cost-effective products by improving flowability, reducing water consumption, and lowering overall production costs.

Paper Retention Aid

Fillers, fines, fibers, and minerals can be selectively retained in the paper sheet by optimizing retention performance. This approach improves paper quality and increases production efficiency. Well-controlled retention also enhances dewatering performance and improves the retention of other papermaking chemicals.

Xinqi Polymer paper retention aid is a highly effective retention agent designed to improve water retention, drainage performance, and machine operation efficiency during the papermaking process. Our retention aids can be used as a single retention system or combined with mineral or organic coagulants.

Characteristics of Xinqi Polymer paper retention aid:

♦ High retention capacity
♦ Good filtration speed
♦ Reduced steam consumption and fewer wet-end breakdowns

Sludge Dewatering

Sludge treatment is an important part of water treatment in the paper industry. It can be performed using filter presses, screw presses, belt presses, and centrifuges.

The goal of sludge dewatering is to achieve maximum water release while maintaining acceptable solids throughput. Technically, each unit has an optimal operating condition where the desired solids throughput and cake moisture content can be achieved. The quality of discharged water from the unit should also be considered.

Xinqi Polymer coagulants used in water treatment are effective sedimentation and centrifugation agents for treating partially digested, activated, or chemically treated waste sludge from the paper industry.

Dispersant Agent

Xinqi Polymer dispersant agents help solid materials disperse easily and remain stable in liquids. Our products can deflocculate solids, significantly reduce dispersion viscosity, and increase solid loading capacity accordingly. 

With shorter dissolving times, Xinqi Polymer dispersant agents are widely used in papermaking applications, including tissues, household papers, writing papers, and napkins.

Characteristics of Xinqi Polymer dispersant agent:

♦ Short dissolving time
♦ Evenly disperses pulp fiber with good forming effects
♦ Enhance dry-wet degree and tension.

Xinqi Polymer is committed to helping customers and the papermaking industry reduce water consumption, improve paper quality, and increase equipment productivity. Moreover, our products are environmentally friendly and economical.

Printing and Dyeing Industry

Polyacrylamide for Printing and Dyeing Wastewater Treatment:

As we all know, the printing and dyeing industry consumes a large amount of water. According to statistics, nearly one hundred tons of water are used for every ton of textiles processed, resulting in a significant amount of sewage and wastewater. Direct discharge of untreated wastewater not only causes environmental pollution but also leads to wasted water resources. Therefore, effective treatment of printing and dyeing wastewater is important not only for environmental protection but also for water recycling and reducing production costs. Printing and dyeing wastewater contains large amounts of fiber impurities, dyes, and chemical residues. Due to its high water volume and changing water quality, it is considered a special type of industrial wastewater that is difficult to treat.

The polyacrylamide produced by Xinqi Polymer for printing and dyeing wastewater treatment can quickly flocculate impurities in wastewater. After sedimentation and other treatment processes, it helps restore wastewater clarity.

What kind of polyacrylamide is used for printing and dyeing wastewater treatment:

Xinqi Polymer is a polyacrylamide manufacturer producing anionic, cationic, and nonionic polyacrylamide products. The molecular weight of anionic polyacrylamide ranges from 4 million to 25 million, while the ionicity of cationic polyacrylamide ranges from 10% to 70%. Since the characteristics of printing and dyeing wastewater vary significantly, the appropriate polyacrylamide specifications are usually determined through wastewater sample testing. This helps ensure effective wastewater treatment while reducing polyacrylamide consumption and lowering treatment costs.

If you are unsure which specifications of wastewater treatment chemicals to use, we can test your water samples and formulate a suitable chemical usage plan free of charge.
