Understanding the Client’s Needs

Project Background

A Zimbabwe-based manufacturer of refractory castables approached Henan Superior Abrasives with a specific request: 96% undensified silica fume packed in 1-ton jumbo bags for a 40ft container shipment. Their priority was to enhance the thermal stability and corrosion resistance of industrial linings in high-temperature environments.

Key Technical Requirements

The client emphasized:

• Purity ≥96% SiO₂ content
• Undensified form for optimal pozzolanic reactivity
• Particle size distribution averaging 0.1–0.3 μm

Why Undensified Silica Fume Excels in Refractory Applications

Superior Material Properties

Unlike densified variants, our undensified silica fume maintains:

• High surface area (15–30 m²/g) for better binding with cement matrices
• Low agglomeration risks during concrete mixing
• Enhanced alkali-silica reaction (ASR) mitigation capabilities

Performance Benefits in Castables

When used in refractory castables, our product delivers:

• 30–40% improvement in thermal shock resistance
• Reduced permeability through nano-filler effect
• Increased service life in furnace linings up to 1,600°C

From Inquiry to Order: Our Customer-Centric Process

Step 1: Detailed Technical Consultation

Within 2 hours of receiving the inquiry, our engineering team:

• Analyzed the client’s operating temperature ranges
• Recommended optimal SiO₂ grade (96U specification)
• Provided technical datasheets and test reports

Step 2: Free Sample Evaluation

We dispatched 2kg of 96U-grade material via DHL Express, including:

• XRF analysis certificate (96.2% SiO₂ verified)
• Bulk density test results: 250–350 kg/m³
• Packaging compatibility confirmation with jumbo bags

Step 3: Production & Quality Assurance

Upon receiving positive sample feedback, we:

• Allocated dedicated furnace for impurity-controlled production
• Conducted 3-stage quality checks (raw material, process, final product)
• Completed container loading within 12 working days
