Applications of Tailong in Industrial Manufacturing

As a direct manufacturer, we deliver Tailong to industrial partners with a clear understanding of its established uses across specific downstream segments. The following scenarios detail the actionable roles of our material in customer production chains, with process, qualification, and integration guidance based on operator practice and actual regulatory frameworks.

1. Water Treatment Chemicals (Coagulant Formulations)

Our material is extensively adopted in the formulation of inorganic coagulants used for industrial and municipal water purification. Technical directors appreciate precise control over dosing to meet regional effluent discharge limits; the compound’s high activity and low residual impurities fit treatment plant workflows focused on compliance and reliable turbidity reduction. Formulators reference drinking water and wastewater standards to set dosage, which differs by water profile and regulatory endpoint.

Industry compliance standards

• NSF/ANSI 60 (Drinking Water Treatment Chemicals – Health Effects)
• AWWA B407/B408 (Specifications for Aluminum-based and Ferric-based Coagulants)
• EN 883:2016 (Chemicals used for treatment of water intended for human consumption)
• ISO 9001:2015 (Quality Management Systems for Chemical Manufacturing)

Typical usage ratio

• Dose range: 5–50 mg/L depending on raw water characteristics and specific removal requirements
• Adjustments made according to influent turbidity, targeted residual metal concentration, and plant throughput rate

Downstream process integration

• Added as a liquid solution or solid during rapid mixing phase after preliminary screening of incoming water
• Mixed for several minutes, then proceeds to flocculation and clarification units

Final product types

• Potable water (municipal and bottled)
• Discharged treated wastewater (compliant with local limits)
• Process water for food & beverage and pharmaceutical industries

2. Paper Manufacturing (Sizing Agent Production)

Purchasing departments in paper mills integrate our raw material as a primary ingredient in wet-end sizing agent formulations. When applied, it reacts with cellulose fibers to enhance paper resistance to liquid penetration. Dosage is calibrated to machine speed, furnish mix, and grade requirements; end-user QC focuses on cobb testing and international printability standards. Application is closely tied to a narrow window ahead of sheet formation.

Industry compliance standards

• ISO 5630-1 (Paper and board – Accelerated aging)
• FDA 21 CFR 176.170 (Paper and Paperboard Components for Food Contact)
• REACH Regulation (EC) No 1907/2006 (Substance Registration and Safety for Paper Chemicals)
• OECD Guidelines for the Testing of Chemicals

Typical usage ratio

• 0.5–3% by weight of dry pulp, adjusted for grammage and end use (writing, printing, packaging)
• Further refinement based on required water resistance and surface print quality targets

Downstream process integration

• Injected directly into the wet-end chest or headbox
• Integrated before retention aids and fillers for uniform fiber distribution

Final product types

• Woodfree writing paper
• Coated printing paper
• Food contact packaging board
• Envelope and label stock

3. Textile Processing (Dye Fixing and Colorfastness Agents)

In dyehouse operations, process engineers deploy our ingredient to formulate fixatives that improve color retention in dyed cotton and synthetic fabrics. The dosage selected hinges on fiber composition and dye class, with lab testing for wash and light fastness as primary acceptance criteria. Compliance checks focus on residual metal content to meet textile end-use markets, especially in apparel and home textiles subjected to European and US regulation.

Industry compliance standards

• Oeko-Tex Standard 100 (Harmful Substances in Textiles)
• ZDHC MRSL (Zero Discharge of Hazardous Chemicals, Manufacturing Restricted Substances List)
• EU REACH Regulation (Chemical Safety in Textile Processing)
• ISO 105-C06 (Tests for Color Fastness to Washing)

Typical usage ratio

• 0.2–1.5% by weight of fiber, fine-tuned for dye class (reactive, direct, acid) and fabric density
• Lower levels for lighter shades, higher for deep or sensitive tones

Downstream process integration

• Introduced during post-dyeing wash-off or final rinsing stage
• Applied in overflow, jet, or padding equipment depending on fabric type

Final product types

• Ready-to-wear apparel and fashion fabrics
• Dyed yarns and threads
• Home furnishings (sheets, towels, curtains)
• Automotive and upholstery textiles

4. Construction Additives (Accelerators in Cementitious Systems)

Cement producers and construction material compounders add our raw material in specialty admixture blends designed to shorten set time and increase early strength. The chosen addition level takes into account ambient temperature and cement type, as well as compliance with global industry benchmarks for admixture safety and performance. Quality assurance includes independent testing for compressive strength development and absence of detrimental side reactions.

Industry compliance standards

• ASTM C494 / C494M (Standard Specification for Chemical Admixtures for Concrete)
• EN 934-2 (Admixtures for Concrete, Mortar, and Grout)
• GB 8076 (China National Standard for Concrete Admixtures)
• ISO 9001:2015 (Production Quality Management for Building Materials)

Typical usage ratio

• 0.1–2.0% by weight of cement, selected based on type (OPC, blended cements) and project setting schedule
• Fine-tuned for targeted slump retention and compressive strength profiles

Downstream process integration

• Blended into dry admixture packages or liquid premixes before batching
• Added to mixer simultaneously with other chemical additives and aggregates

Final product types

• Ready-mixed concrete for structural applications
• Precast concrete components (beams, panels, pipes)
• Shotcrete for tunnel lining and slope stabilization
• Underwater and cold-weather concrete mixtures

5. Leather Tanning (Retanning and Mineral Tanning Agents)

Specialist tanneries source our material as a mineral-based retanning agent, primarily to impart firmness, fullness, and improved grain tightness in chrome or vegetable-tanned leathers. Dosage levels synchronize with hide type, tanning system, and mechanical processing plans. Audits reference global leather regulations controlling allowable mineral residues and downstream emission standards, ensuring both operator safety and environmental compliance.

Industry compliance standards

• ISO 5398 (Determination of Metal Content in Leather)
