Application Scope：
The sweat test chamber is designed to evaluate the resistance of materials or products to corrosion caused by human perspiration or saline solutions. It simulates the effects of sweat secreted by human skin on products during actual use.The primary purpose of this equipment is to assess product quality and service life, as well as to verify product safety for human contact. It is widely used in product research and development, manufacturing processes, and quality control.The sweat test chamber is suitable for testing a wide range of materials and products, including jewelry, eyewear, electroplated components, paint and coating films, mobile phones, plastics, textiles, metals, surface coatings, printed products, leather, and related materials.
Product Introduction：
The eyewear frame sweat corrosion test chamber is designed to evaluate the resistance of eyeglass frames to perspiration corrosion, ensuring that frames can be safely worn for two years or longer. It effectively prevents discoloration, coating degradation, or peeling caused by sweat corrosion, which could otherwise pose serious risks to the wearer’s health and safety.This equipment is a dedicated sweat testing system for eyeglass frames, developed in accordance with standards such as ISO 12870. It is equipped with an advanced temperature control system to maintain stable and continuous test temperatures. The freely adjustable timer and temperature controller allow flexible setting of test duration and temperature to meet the requirements of different testing standards.
The test chamber uses imported glass containers with excellent corrosion resistance and impact resistance, and is fitted with comprehensive safety protection devices. These features not only ensure safe operation during testing, but also provide clear visual observation of the entire test process, allowing operators to monitor test conditions and progress in real time.
Test Principle：
The operating principle of the sweat resistance tester is to continuously drip artificial sweat containing NaCl or saline solution onto the surface of the test specimen at room temperature for a specified period of time. This process simulates perspiration conditions experienced by the human body during physical activity and daily use, in order to evaluate the performance and service life of the specimen.After completion of the test, laboratory instruments and analytical equipment are used to analyze and quantitatively assess the degree of performance degradation of the sample, thereby providing a scientific basis for product evaluation and quality control.
