Application of Auxiliaries in Papermaking Wastewater Treatment

June 29, 2026 admin No Comments

In modern paper mills, closing the water loop is a major priority. Because white water is aggressively recycled, the wastewater that eventually leaves the mill is highly complex, heavily laden with cellulose microfibers, lignin derivatives (hemicellulose), fillers (like CaCO3 and clay), starch sizing agents, and residual process chemicals. Treating this effluent effectively requires a carefully choreographed…

Applications of Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)

June 27, 2026 admin No Comments

AA/AMPS (Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer) is a high-performance, multi-functional water-soluble polymer. Its molecular structure combines carboxylic acid groups (from acrylic acid) and strongly polar sulfonic acid groups (from AMPS). This dual-functional design gives AA/AMPS exceptional calcium tolerance, thermal stability, and particle-dispersing capabilities, making it a critical additive across several heavy industries. 1. Industrial Water…

Properties and Applications of HEDP•Na4 Granules

June 26, 2026 admin No Comments

HEDP•Na4 (Tetrasodium 1-Hydroxy Ethylidene-1,1-Diphosphonate) Granules represent the solid, alkaline salt form of HEDP. While the liquid acid form is a standard for direct chemical blending in liquid water treatment loops, the granular solid is specifically manufactured to overcome handling, shipping, and compounding limitations. It provides the exact same scale and corrosion inhibition as liquid HEDP…

What products are included in the category of anti-mold agents?

June 25, 2026 admin No Comments

The category of anti-mold agents—often referred to professionally as antimicrobials, fungicides, fungistats, or mildewcides—is divided into several distinct product types based on their chemical composition and application. Biocide They generally fall into the following core product categories: 1. Hard-Surface Disinfectants & Remediation Sprays These are ready-to-use liquid products designed to instantly kill active mold spores,…

Is PESA a papermaking-specific auxiliary agent?

June 24, 2026 admin No Comments

No, PESA (Polyepoxysuccinic Acid) is not a papermaking-specific auxiliary agent. While it certainly finds use in the paper industry, it is primarily categorized as a green, phosphorus-free, biodegradable scale inhibitor and dispersing agent with broad applications across multiple industries. Its unique, nitrogen-free and phosphorus-free structure allows it to replace traditional water treatment chemicals that cause…

Application of MA-AA.Na in Textile Printing and Dyeing

June 22, 2026 admin No Comments

MA/AA.Na (Maleic Anhydride/Acrylic Acid Copolymer Sodium Salt) is a highly effective chelating dispersant and anti-redeposition agent in the textile industry. Because it combines the distinct properties of both maleic and acrylic acid monomers, it offers superior thermal stability and higher calcium chelating capacity than PAAS (Sodium Polyacrylate) alone. It is widely utilized across the preprocessing,…

Are the costs of using papermaking auxiliaries high?

June 17, 2026June 17, 2026 admin No Comments

The absolute cost of papermaking auxiliaries is not “high” when viewed as a percentage of total paper mill operational expenditures (OpEx). However, because they are high-value specialty chemicals, their unit price is high, and they carry an incredibly high “leverage” over a mill’s profitability. To look at how auxiliary costs break down in real-world mill…

Can PBTC be used as a stabilizer?

June 16, 2026 admin No Comments

Yes, PBTC is highly effective and widely used as a chemical stabilizer. While its primary classification is an industrial scale and corrosion inhibitor, its unique chemical structure—specifically its ability to bind tightly to metal ions and withstand aggressive environments—makes it an exceptional stabilizer across several distinct chemical and industrial applications. Here is how and where…

What is a degreasing detergent?

June 15, 2026 admin No Comments

A degreasing detergent (often just called a degreaser) is a specialized cleaning chemical explicitly formulated to break down, lift, and dissolve water-insoluble substances like grease, oils, fats, waxes, and tars. While regular soaps and detergents are great for everyday dirt and dust, they struggle with heavy organic oils. A degreasing detergent bridges that gap by…

Precautions for the Use of Disperse Printing Auxiliaries

June 13, 2026 admin No Comments

To ensure optimal print quality, shade reproducibility, and a safe production environment, processing engineers and line operators must manage several critical variables when handling disperse printing auxiliaries. Because these chemicals interact closely with the physical properties of synthetic fibers (like polyester) and the chemical stability of disperse dyes, slight deviations can cause major production defects….
