Product Specifications: Calcium & 리그노술폰산나트륨
칼슘 리그노술폰산염
This product appears as a consistent brown powder. Moisture stays controlled at ≤7.0% for stable storage. Its pH value ranges from 8 to 11 for safe mixing. Dry matter content reaches ≥92% for high purity. Lignosulfonate purity is ≥55% to ensure performance. Inorganic salt content stays 5.0% 이하 to avoid negative effects. Total reducing matter limits at 4.0% 이하. Water insoluble matter is 1.5% 이하. Calcium and magnesium total 1.0% 이하. All test results meet strict international standards.
Sodium Lignosulfonate CL‑SLS
It presents a yellow‑brown to brown free‑flowing powder. pH value ranges 7–9 for broad compatibility. Dry matter is ≥93% for concentrated effectiveness. Moisture is ≤7.0%, often below 5.0% in real batches. Water insoluble matter is ≤1%, typically ≤0.5%. Lignosulfonate reaches ≥55%, industrial grade up to 70%. High‑end grade can hit ≥94% for special uses. Total reducing matter is ≤6.0%, usually 4.0% 이하. These parameters fit demanding concrete applications.
Road & Pavement Concrete Applications
Our lignosulfonates work great for road and pavement projects. They serve as effective, eco‑friendly concrete water reducers. Sodium lignosulfonate fits many pavement‑related scenarios. It supports mass concrete for durable highway bases. It improves fluidity for pumped pavement concrete. It works for commercial concrete in hot summer paving. It delays setting for long‑distance transport on job sites. It suits bored piles and pipe piles under roads. It aids underground structures supporting road networks.
This additive cuts water usage by 9–11% in proper dosages. It boosts early and long‑term concrete strength clearly. Three‑day strength rises 20–30% for fast opening. Seven‑day strength grows 20–30% for stable development. It raises 28‑day strength by 15–20% for long service life. It saves 8–10% cement while keeping slump and strength. It delays initial and final setting by over 3 hours. It pushes hydration heat peaks 5 hours later. It enhances freeze‑thaw and impermeability performance. It causes no corrosion to steel or road aggregates. Calcium lignosulfonate also boosts mix workability for paving. It improves cohesion and reduces surface defects. Both products lower costs and extend pavement life.
Packaging, Storage & Global Transport
We use secure, export‑friendly packaging for all orders. Standard packing is 25 kg multi‑layer bags. Bags have plastic liners to block moisture. We also offer 500–1000 kg bulk bags for large orders. All bags carry clear labels for easy identification. Labels show product name, weight, lot, and storage tips.
Store goods in dry, well‑ventilated warehouses. Keep bags away from direct sun and heavy rain. Avoid contact with strong acids, alkalis, or oxidizers. Stack bags neatly and follow height limits. Handle bags gently to prevent tearing or punctures. Slight caking does not harm performance after mixing.
Our products are non‑toxic and non‑hazardous for shipping. They are not flammable or explosive for safe transport. We support sea, rail, and truck freight worldwide. We use covered trucks or containers to shield from weather. We secure loads to avoid shifting during long trips. Our 15‑year export record ensures smooth customs clearance. We prepare full documentation quickly for every country. We coordinate closely with carriers and freight forwarders. Clients get consistent tracking and timely arrival updates.
