UT4028 Geosynthetic material Geotextile acid and alkali resistance tester mainly use to test the corrosion resistance of geosynthetics (geotextiles, geomembranes, geogrids, etc.) in acidic or alkaline solutions;

The resistance to acid and alkali erosion of the material was evaluated by comparing the mechanical properties (such as tensile strength, tear strength, etc.) before and after soaking.

Geotextile acid and alkali resistance tester is suitable for water conservancy projects, landfills, chemical pollution sites and other scenarios that require corrosion-resistant materials.

Test principle

The specimen is soaked in a specific concentration of acid solution (such as sulfuric acid, hydrochloric acid) or alkali solution (such as sodium hydroxide) and held at a constant temperature for a specified time; After the sample is removed, its mechanical properties are tested according to standard methods (such as tensile test), and the performance retention rate or change rate is calculated to determine the corrosion resistance level of the material.

Geosynthetics (such as geotextiles, geomembranes, etc.) are often exposed to corrosive media such as acid and alkali in water conservancy, transportation, environmental protection and other projects, and their corrosion resistance directly affects the durability of the project. Acid and alkali resistance tester is a professional equipment used to simulate the performance changes (such as strength, elongation, etc.) of materials after immersion in acid and alkali solutions, mainly used to evaluate the chemical resistance of materials.
