YBB00022005-2 Glass Infusion Bottle Alkali Resistance Experimental Device

The alkali resistance of glass products is one of the key factors affecting their product quality and safety. In alkaline environments, glass may be corroded, leading to a decrease in performance and even breakage. By measuring the corrosion resistance of glass to boiling mixed alkaline aqueous solutions, potential quality issues can be identified and resolved in a timely manner, ensuring that glass products maintain good physical and chemical properties in the expected application environment, thereby ensuring product quality and safety.

By measuring the corrosiveness of glass in boiling mixed alkaline aqueous solutions, the tolerance of glass materials to alkaline environments can be quantitatively evaluated. This is of great significance for selecting glass materials suitable for specific alkaline environments, especially in industries such as chemical, pharmaceutical packaging, and electric light sources, where glass products often need to come into contact with alkaline solutions. It is recommended to use the glass alkali resistance testing device NJT-03S produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. for testing the boiling alkali water resistance of medicinal glass container products such as glass infusion bottles, oral liquid bottles, ampoules, penicillin bottles, etc. Meet the 2025 version of drug packaging material standards.

Principle of alkaline resistance test device for glass infusion bottles

1. Erosion effect: The main component of glass is silicate, which may undergo chemical reactions in alkaline environments, leading to erosion of the glass surface. The rate and degree of erosion depend on the composition and structure of the glass, as well as the concentration and temperature of the alkaline solution.

2. Quality loss: By measuring the mass change of glass samples before and after immersion, the mass loss per unit surface area can be calculated. This quality loss reflects the corrosion resistance of glass in alkaline environments.

3. Grading evaluation: Based on the quality loss per unit surface area, the alkali resistance of glass can be classified into different levels, such as low etching resistance, weak etching resistance, and high etching resistance. This grading evaluation helps to understand the performance of different glass materials in alkaline environments and provides reference for selecting suitable glass materials.
