Soda ash light grade

Description

1. Product Overview
Soda Ash Light Grade (Disodium Carbonate) is a high-purity alkaline compound essential for pH regulation and chemical synthesis. It is primarily used in flat glass, container glass, detergents, and sodium bicarbonate production. The key value proposition is its consistent 99.2% minimum purity, low chloride content, and free-flowing granular structure that enhances process efficiency. Strategically, it remains the most cost-effective alkali source globally, underpinning heavy industries where supply chain reliability directly impacts operating margins.

2. Key Specifications & Technical Characteristics

• Chemical composition: Na₂CO₃ ≥ 99.2%, NaCl ≤ 0.7%, Na₂SO₄ ≤ 0.03%, Fe₂O₃ ≤ 0.003%

• Purity grade: Light industrial grade, meeting GB 210.1-2004 / ISO 740:1976 standards

• Physical characteristics: White fine powder, bulk density 0.5–0.6 g/cm³, mean particle size 90–150 μm, free-flowing without caking

• Packaging options: 25 kg or 40 kg PP/PE woven bags, 1 MT jumbo bags, or pneumatic tanker trucks

• Shelf life: 24 months in dry, covered storage away from acids and moisture

3. Core Industrial Applications

• Glass manufacturing (60% of global demand): As a fluxing agent reducing melting temperature of silica; preferred over dense grade for batch mixing uniformity and faster dissolution.

• Detergents & soaps: Provides alkalinity for surfactant efficiency and water softening; outperforms caustic soda in handling safety and cost per unit of alkalinity.

• Chemical processing: Feedstock for sodium silicates, bicarbonates, phosphates; chosen for consistent reactivity and low heavy-metal content.

• Water treatment & pulp/paper: pH adjustment and lignin removal; cost advantage over lime due to lower sludge generation.

4. Competitive Advantages

• Quality consistency: Every batch tested for particle size distribution and purity; <2% CV across annual production.

• Supply reliability: Year-round capacity from natural trona and Solvay process plants; no seasonal volatility.

• Logistics capability: Dedicated bulk vessels and container loading from major ports (China, Turkey, USA, India); lead times 15–30 days.

• Price competitiveness: Long-term contracts with volume-based discounts; benchmark-linked pricing transparently documented.

• Sustainability: Low-carbon trona-derived product available; no effluent discharge in upstream processing.

• Technical support: SDS, COA, and process optimization guides included with every commercial order.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (one 20’ FCL)

• Bulk loading capacity: 25–27 metric tons per 20’ dry container; 1,200–1,500 MT per Handysize vessel for breakbulk
