Industrial Production and Manufacturing

Industrial Production and Manufacturing — Dual Protection for Process Precision and Media Purity

In fine chemicals, coatings, papermaking, printing and dyeing, and other manufacturing industries, our products are key additives for solving production process challenges.

1. Defoamers: From "eliminating foam" to "regulating gas-liquid equilibrium"

In industrial processes, foam not only affects operational safety (such as overflow and inaccurate metering), but is also a major cause of product defects (pinholes, orange peel, surface flaws) and reduced equipment mass transfer efficiency.

Deep technical insight: The stability of industrial foams is typically determined by two factors—the surfactant adsorption layer and the high-viscosity liquid film between bubbles. Conventional defoamers can only break bubbles temporarily and fail to provide long-term suppression.

Our technical solution:

Specialty polyether-modified silicone oil: We use a "comb-like" structured polyether-grafted silicone oil, which combines the low surface tension (~21 mN/m) of organosilicones with the self-emulsifying and long-lasting defoaming properties provided by polyether segments. Under high temperature and pressure conditions (such as in viscous polymerization reactors), its cloud point effect enables the automatic release of active defoaming agents upon reaching a specific temperature, achieving intelligent foam control.

High-shear application: For high-speed grinding in coatings and paper coating processes (line speed >1000 m/min), we offer defoamers thickened with hydrophobic fumed silica. Under high shear forces, the hydrophobic particles rapidly capture fine bubbles, coalescing them into larger bubbles that rise to the surface, effectively eliminating "cratering" and "fish-eye" defects in paint films and improving the gloss of the final product.

Data quantification: In typical water-based coating systems, our addition level of only 0.05% to 0.1% can reduce the system's air content from 15% to 20% down to below 3%, significantly improving pumping efficiency and coating uniformity.

Flocculant: From "Solid-Liquid Separation" to "Resource Recovery"

The core of industrial wastewater treatment has shifted from "meeting discharge standards" to "resource recovery" and "zero discharge." In this context, flocculants serve not only as purification agents but also as tools for concentration and enrichment.

In-depth technical insight: Industrial wastewater often contains large amounts of colloidal particles that are difficult to settle, as well as highly charged dissolved substances (such as textile dyes and papermaking fiber fillers). Simple polyaluminum chloride (PAC) is insufficient to handle high organic loading.

Our technical solution:

High-Density Sludge (HDS) Process: In mining and electroplating wastewater treatment, we use high-molecular-weight anionic polyacrylamide (molecular weight >18 million), combined with lime and iron salts, to form large, compact flocs. The settling velocity can reach 3–5 times that of conventional processes, increasing the underflow sludge concentration to 40%–50%, significantly reducing the operating load on filter presses.

Targeted removal of specific ions: By synthesizing thiolated or aminated modified coagulants, these agents gain the ability to chemically chelate heavy metal ions (such as Hg²⁺ and Cu²⁺), achieving a dual effect of "coagulation + chelation" and ensuring that the effluent heavy metal concentration remains below 0.05 ppm.

Papermaking Wet End Chemistry Control: In the papermaking process, we supply cationic organic flocculants that, through charge neutralization, efficiently retain fibers, fillers, and fine colloids in the paper. This not only improves retention rates in the first pass (15%–25%) but also significantly reduces white water turbidity, enabling closed-loop recycling of papermaking white water.
