---

1. Product Overview

This product is a composite mineral impermeable material prepared using a special formulation and process. Through scientific compounding and optimized treatment, it is specifically designed to address the challenges of long-term impermeable isolation under high-saline, high-pollution environments. The material system has been verified to meet the extreme requirements of impermeable and adsorption performance for major engineering projects such as nuclear power plant decommissioning remediation and land reclamation.

2. Core Mechanisms and Advantages

2.1 Dual Protection, Advanced Mechanism

1. Physical Dense Barrier: The material forms a low-porosity dense structure after compaction through unique particle gradation, creating an effective physical barrier that blocks the migration of water and harmful ions.
2. Chemical Adsorption and Stabilization: The material system exhibits significant adsorption and immobilization potential for heavy metal ions and radioactive nuclides, contributing to in-situ stabilization of pollutants.

2.2 Excellent Environmental Tolerance

1. Strong Alkali Resistance: Optimized for marine and high-saline geological environments, maintaining structural stability under high-salinity conditions and overcoming the shortcomings of traditional materials that tend to fail in saline environments.
2. Long-term Performance Stability: Mineral-based materials are resistant to aging and chemical corrosion, meeting the requirements of long-term engineering service life.

2.3 Balanced Engineering and Economic Performance

1. Good Construction Adaptability: With optimized moisture content and particle size, the material facilitates on-site spreading and compaction, making quality control easier.
2. Comprehensive Cost Advantage: While providing high performance, the scientific formulation design achieves more competitive lifecycle costs.

3. Key Quality Control Indicators

To ensure product consistency, each batch of products leaving the factory meets the following strict internal control standards:

Item	Control Indicator	Test Standard	Significance
Fineness (200 mesh sieve residue)	≤ 8%	GB/T 6005	Ensures main particle fineness, facilitating dense structure formation
Moisture Content	≤ 12%	GB/T 50123	Ensures storage stability and construction convenience
pH Value (5% water suspension)	8.0 - 10.0	GB/T 9724	Ensures stable weakly alkaline chemical properties

Note: Core engineering performance of the material (such as permeability) requires special design and verification based on specific project conditions.

4. Main Application Fields

This material is specifically designed for high-standard permanent pollution isolation and ecological protection engineering, particularly suitable for:

1. Environmental Safety and Remediation: Contaminated site isolation barriers, liner and cover systems for solid waste landfills
2. Marine and Water Conservancy Engineering: Foundation impermeable systems for land reclamation, liner systems for high-salinity storage tanks
3. Mining and Energy Engineering: Tailings pond seepage control, salt cavern storage facility sealing, and other engineering applications
