Green and Safe Bentonite Geosynthetic Clay Liner for Environmental Protection in Municipal Engineering

 Green and Safe Bentonite Geosynthetic Clay Liner for Environmental Protection in Municipal Engineering

Product Introduction

Sodium-based bentonite waterproof blanket is a blanket-shaped material made from sodium-based bentonite (also known as sodium-based montmorillonite) as the main raw material. It is made by mixing graded natural sodium-based bentonite particles with corresponding additives to form raw materials, and then processed into a blanket-shaped waterproof roll by needling technology and equipment, which fixes the bentonite particles between the geotechnical fabric and plastic woven fabric. It can also be processed by needle-punched coating or adhesive bonding.

Product Properties

1. Excellent waterproof performance: sodium bentonite has a very high self-water retention performance, and can rapidly expand to form a dense diaphragm after encountering water, effectively preventing groundwater penetration.
2. Good durability: Because bentonite is a natural inorganic material, it will not suffer from aging or corrosion, so its waterproof performance is durable.
3. Environmental protection: Bentonite is a natural material, harmless to the human body and the environment, and belongs to green environmental protection materials.
4. Simple construction: Bentonite waterproof blanket construction process is simple and fast, suitable for a variety of complex terrain and environmental conditions under the waterproof project.
