Applications of Sodium Lignosulfonate in the Construction Industry Sodium lignosulfonate, a natural polymer derived from the waste liquor of wood pulping, is widely used in the construction field—particularly in concrete and cement-based products—due to its excellent dispersing, water-reducing, air-entraining, and retarding properties. Below are its primary applications in construction: 1. Concrete Water-Reducing Admixture Sodium lignosulfonate is one of the most common types of ordinary water-reducing agents, sometimes referred to as "lignin-based plasticizers." Mechanism: Its anionic groups adsorb onto cement particles, creating electrostatic repulsion that disperses the particles, releasing trapped water and thereby reducing the water-cement ratio. Benefits: Enhances concrete workability and fluidity (improved slump). Reduces water demand by 10–15% while maintaining workability, increasing concrete strength and durability. Low cost, widely available, and environmentally friendly. 2. Retarder Sodium lignosulfonate exhibits retarding properties by slowing down the hydration rate of cement. Applications: Hot-weather concreting to prevent premature setting. Mass concrete pours, helping to control heat buildup and reduce thermal cracking. Ready-mix concrete transported over long distances, extending workability time. Note: The degree of retardation depends on dosage, cement type, and temperature. Proper dosage must be determined through testing to avoid excessive delay in setting. 3. Air-Entraining Agent (Secondary Effect) During dispersion, sodium lignosulfonate can introduce small, stable air bubbles into the concrete mix. Benefits: Improves freeze-thaw resistance by providing pressure relief voids for expanding water. Enhances cohesiveness of fresh concrete, reducing bleeding and segregation. Note: The air content is typically low and difficult to control precisely. Dedicated air-entraining agents are preferred if higher air content is required. 4. Component in Composite Admixtures Sodium lignosulfonate is often used as a base ingredient in composite admixtures, blended with other additives (e.g., high-range water reducers, accelerators, waterproofing agents) to achieve balanced performance. For example: Blended with naphthalene-based or polycarboxylate-based superplasticizers to reduce cost and improve workability retention. 5. Other Construction-Related Applications Soil Stabilizer: Used in road bases or soil improvement to enhance cohesion and erosion resistance. Dust Suppressant: Applied on construction sites or material stockpiles to control airborne dust. Additive in Gypsum Products: Improves flowability and strength of gypsum slurries. Usage Considerations Dosage Control: Typically 0.2–0.3% by weight of cement; optimal dosage should be determined via testing. Overuse may cause excessive retardation, high air content, or reduced strength. Compatibility: May interact differently with various cements or other admixtures; compatibility testing is recommended. Quality Consistency: As a natural product, performance can vary between batches; consistent quality control is essential. Summary As an economical and eco-friendly natural polymer admixture, sodium lignosulfonate plays a significant role in improving concrete workability, reducing water content, and controlling setting time in the construction industry. Although its water-reducing and strength-enhancing effects are less pronounced than those of high-performance admixtures, its balanced performance and low cost ensure its continued relevance in general concrete applications and composite formulations. With the growing emphasis on sustainable construction materials, sodium lignosulfonate remains a valuable and promising additive.

The applications of Sodium Lignosulfonate in agriculture are diverse, leveraging its properties as a dispersant, binder, and plant growth regulator.

These applications not only help to enhance agricultural production efficiency but also contribute to agricultural sustainability to some extent. However, when applying specifically, it is necessary to reasonably select and use based on crop types, soil conditions, and specific agronomic measures.

The specific applications of sodium lignosulfonate as a concrete admixture mainly revolve around its role as an effective water reducer and dispersant, which significantly improve the workability of concrete. Here are the key points: Enhanced Flowability: Sodium lignosulfonate substantially increases the flowability of concrete mixes, making it easier to pour and compact without increasing water content, thus enhancing construction efficiency. Water Reduction: As a high-efficiency water reducer, it decreases the amount of water required in the concrete mix. This not only helps maintain or improve the workability of the concrete but also enhances the strength and durability after hardening by reducing the water-cement ratio. Strength and Durability Improvement: By optimizing the water-cement ratio, sodium lignosulfonate contributes to producing high-strength and high-durability concrete. Lowering the water content reduces porosity, improving density and impermeability of the hardened concrete. Control of Setting Time: In certain cases, sodium lignosulfonate can influence the setting time of concrete, depending on the specific formula and dosage. This feature is particularly useful for large volume concrete projects that require extended transportation or operation times. Performance Under Harsh Conditions: In cold climates, sodium lignosulfonate can help prevent early frost damage; in hot environments, it assists in slowing down the evaporation rate, preventing the concrete surface from drying out and cracking prematurely. Environmental Benefits: Since sodium lignosulfonate is a byproduct of the papermaking industry, using it as a concrete admixture represents a form of resource recycling, contributing positively to environmental protection. In summary, the application of sodium lignosulfonate as a concrete admixture not only improves the workability of fresh concrete but also significantly boosts the overall quality and lifespan of hardened concrete, making it a crucial chemical admixture in modern construction projects.

The quality standards for purified air for biological fermentation mainly include sterility, dryness, a certain temperature and a certain pressure   [1] Sterility: During the fermentation process, the air must be strictly filtered and sterilized to ensure that no microorganisms are introduced, thus avoiding contamination of the fermentation process. The requirement of sterility is reflected in the cleanliness of the air, which generally requires that only one bacteria is allowed to pass through in 1000 service cycles, that is, the sterility of the filtered air is N=10^-3 1   [2] Drying: During the fermentation process, the relative humidity of the air should be controlled at ≦70% to ensure the dryness of the air and avoid excessive humidity affecting the fermentation process   A certain temperature: the air temperature entering the fermenter can be 10~30 °C higher than the incubation temperature, which is to adapt to the temperature requirements of different fermentation processes and ensure that the fermentation process is carried out at a suitable temperature   A certain pressure: the pressure of the air is generally 0.2~0.4 MPa, and a certain positive pressure is maintained to help prevent the entry of external pollutants.   In addition, the purified air used for fermentation also needs to be compressed by oil-free lubricating air, stored in tanks, cooled, primary filtration, secondary filtration, etc., to ensure that the quality of the air meets the needs of the fermentation process.   These treatment steps are designed to remove microorganisms, dust, and other contaminants from the air, providing a clean, sterile environment for the fermentation process
