產品介紹：

膨潤土復合防水毯（GCL）是一種新型土工合成材料，它是由一層粘土或其它低滲透性礦物

材料外膜土工織物或土工膜，通過針刺或縫合的方法制成的的復合防滲材料，本公司所采用的是高膨脹性的鈉基膨潤土，其特點是遇水后膨脹，產生水合作用，形成不透水的凝膠體，同時此種膨潤土還有儲存水分的能力，其吸收、含水量可達自身重量的10倍以上

產品特點

與土工膜相比，其優越性主要表現在：

a）密實防水隔水性能好，膨潤土在法向水壓狀態下形成密實不透水的凝膠隔膜層

b）柔性好，能較好的適應不均勻沉淀。

c）長久的防水能力，膨潤土是天然無機礦物材料，不會發生腐蝕和老化現象

d）吸水厚度增大幾倍，不易被頂破，即使在頂破情況下也具有自我修補能力

 用途作用

主要應用于環境工程中的廢棄物填埋場、地下水庫、地下基礎設施建設等工程中，解決密封、隔離、防滲漏等問題，效果好，抗破壞性強。

Product Introduction

Bentonite geosynthetic clay layer is a new type of geotechnical synthetic material. It is a composite impervious material made of a layer of clay or other low-permeability mineral material, outer membrane geotextile or geomembrane, which is made by needle punching or stitching. Our company uses high-expansion sodium bentonite, which is characterized by its expansion after water contact, resulting in hydration and the formation of a water-impermeable gel. This bentonite also has the ability to store water. Water up to 10 times its own weight.

 Features

Compared with geomembrane, its superiority is mainly manifested in:

a) Compact water-proof and waterproof performance, bentonite forms a solid water-impermeable gel membrane layer under normal water pressure

b) Good flexibility, can better adapt to uneven precipitation.

c) Long-term waterproof capacity, bentonite is natural inorganic mineral material, no corrosion and aging

d) The water absorption thickness increases several times, it is not easy to be broken, and it has self-repair ability even in the case of top break

Application:

It is mainly used in landfills, underground reservoirs, and underground infrastructure construction projects in environmental engineering to solve problems such as sealing, isolation, and leakage prevention, with good results and strong resistance to damage.
