Chemical polishing is a method of eliminating wear marks and etching and leveling by chemical agents on the selective dissolution of uneven areas on the surface of the sample. Chemical polishing Chemical polishing is a method of eliminating wear marks and etching and leveling by chemical reagents for selective dissolution of uneven areas on the surface of samples.
Advantages of chemical polishing Chemical polishing equipment is simple and can handle parts with more complex shapes.
Disadvantages of chemical polishing 1. The quality of chemical polishing is not as good as that of electrolytic polishing.
2. The adjustment and regeneration of the solution used for chemical polishing is difficult and limited in application.
3. During the chemical polishing operation, nitric acid emits a large amount of yellow-brown harmful gas, which is very serious to the environment.

Geosynthetic clay liners (GCL) are high performance needle punched environmental reinforced composites which combine two durable Geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-Woven Geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
Applications:
The water proof bentonite pad is mainly used in penetration-proof,airproof &separation in rubbish burying square,man-made lake,channel,pool,basement,subway,etc.
The production line processing of finished products with high peel strength, strong pulling hardness, low permeability.
