Calcium Lignosulfonate Powder

Calcium Lignosulfonate Powder – Natural Bio-Polymer Dispersant from EverStar Group

When you're looking for a cost-effective, environmentally sustainable dispersant for concrete, feed, or industrial Applications, Calcium Lignosulfonate Powder from EverStar Group delivers unmatched value. With over 13 years of manufacturing expertise and a large-scale production capacity of 5,000+ tons of inventory, we supply this natural bio-polymer directly from our own factory to more than 50 countries worldwide. Our product features a lignosulfonate content ≥55%, calcium content of 3-5%, and a pH range of 4.0-6.0, ensuring consistent performance across batches. You get factory-direct pricing, EU REACH compliance, and full technical support—all backed by a 99.5% on-time delivery rate.

What Makes Our Product Stand Out?

Our calcium lignosulfonate is a renewable, biodegradable dispersant derived from wood pulp sulfite processing. You benefit from 30-50% cost savings compared to synthetic alternatives like NNO or MF, without compromising performance.

The complex molecular structure—featuring sulfonic, phenolic, and hydroxyl functional groups—provides powerful adsorption onto particle surfaces. This creates both electrostatic repulsion and steric hindrance, keeping suspensions stable and improving workability in your formulations.

You'll appreciate its versatility across multiple industries: concrete admixtures, animal feed binders, carbon black dispersants, dust control agents, and ceramic processing aids.

Where You Can Use It?

Concrete and Construction:

When you add our powder to your concrete mix, you achieve 8-12% water reduction while maintaining the same slump. Under equal slump conditions, you'll see 28-day compressive strength reach 110%~120% of your reference mix due to lower water-cement ratio. If you maintain the same water dosage, early strength may be slightly lower, but 28-day strength matches your baseline. You also gain improved pumpability, extended workability time, and enhanced freeze-thaw resistance through controlled air entrainment.

Animal Feed Pelleting:

Your feed pellets gain superior mechanical strength and durability. The calcium content provides nutritional value—particularly valuable in aquaculture and poultry formulations where you want to avoid excess sodium. You'll reduce fines during handling and transport, improving feed conversion ratios and reducing waste.

Carbon Black Dispersion:

You can achieve uniform dispersion in rubber compounding and ink formulations. The high-temperature stability ensures consistent performance even in demanding processing conditions.

Dust Control:

The lower water solubility (compared to sodium lignosulfonate) gives you longer-lasting dust suppression on unpaved roads, mining sites, and bulk material storage areas. Your application remains effective through multiple weather cycles.

Ceramic and Refractory Materials:

You'll reduce slip viscosity significantly, making casting and shaping operations easier. Green body strength improves, reducing breakage during handling before firing.

Why Choose EverStar Group?

Steady Supply Chain:

Our devoted bulk capacity tank cultivate and robotized generation lines guarantee you never confront supply intrusions. Whether you require a trial clump or full holder loads, we react quickly.

Strict Quality Control:

Every bunch experiences comprehensive testing—from lignosulfonate substance (UV spectrophotometry) to decreasing sugar levels, dampness substance, pH steadiness, and chloride particle examination. You get a Certificate of Investigation (COA) referencing GB/T 8077 or ASTM C494 guidelines with each shipment.

Customization Support:

Our in-house R&D research facility can create custom-made details inside 24 hours. Require a particular molecule estimate conveyance or adjusted calcium substance? Our chemical engineers work specifically with you to meet your correct requirements.

Global Compliance:

We keep up EU REACH enlistment and ISO Certifications. You can certainly purport our items knowing they meet universal security and natural standards.

Important Usage Guidelines

Dosage Exactness Matters:

For concrete applications at 20-35°C utilizing standard Portland cement, commonplace dose ranges from 0.03% to 0.15% by weight of cement. At these levels, you can anticipate impediment of 2-7 hours. Higher doses drawing closer the constrain may amplify this to 8 hours.

Avoid Overdosing:

Slight overdosing up to 0.2% ordinarily comes about in reasonable impacts when you keep up appropriate sodden curing—final quality remains basically typical. Be that as it may, if you surpass 0.2%-0.3%, you'll involvement 24-72 hour hindrance, altogether diminished early quality, and 5-10% lower 28-day quality. Surpassing 0.3% causes extreme over-retardation with potential long-term non-setting, rendering your concrete unusable.

Storage Recommendations:

Keep the powder in fixed packs absent from dampness. Store in a cool, dry distribution center with great ventilation. Beneath appropriate conditions, rack life amplifies to 24 months without debasement.

Calcium vs. Sodium Lignosulfonate

You might wonder which variant suits your needs better. Our calcium version has lower water solubility (approximately 50 g/100mL vs. 70 g/100mL for sodium).

In concrete, calcium ions provide mild acceleration, while sodium versions offer neutral to slightly retarding effects. For animal feed, you'll prefer the calcium variant—it adds nutritional value without introducing unwanted sodium. For dust control, the lower solubility of Calcium Lignosulfonate Powder provides longer-lasting surface stabilization.

We produce both variants from consistent softwood feedstock, so you can switch between them or use both depending on your application portfolio.

FAQ

Q: How much can I diminish my dispersant costs?

A: You'll ordinarily spare 30-50% compared to engineered dispersants like naphthalene sulfonate (NNO) or melamine formaldehyde (MF) whereas accomplishing comparable scattering performance.

Q: Is this item naturally safe?

A: Yes. It's determined from renewable wood mash, is completely biodegradable, and has the most reduced carbon impression among mechanical dispersants. It complies with universal natural controls counting EU REACH.

Q: What's your least arrange quantity?

A: We offer adaptable MOQ beginning from trial bunches. For full holder loads, you advantage from the most competitive factory-direct estimating. Contact Us to examine your particular volume needs.

Q: Can you give tests for testing?

A: Completely. We offer free test testing bolster so you can confirm execution in your definitions some time recently putting a bulk arrange. Tests regularly dispatch inside 48 hours.

Q: How do you guarantee batch-to-batch consistency?

A: Our robotized generation lines and strict quality control conventions keep up reliable lignosulfonate substance, calcium levels, pH, and molecule measure dissemination. You get full COA documentation with each shipment, and our 13 a long time of fabricating encounter guarantees dependable performance.

Q: What specialized bolster do you provide?

A: Our group of chemical engineers offers full lifecycle support—from introductory item interview and dose suggestions to investigating and after-sales specialized help. You work straightforwardly with committed account directors who get it your particular industry necessities.
