Hangzhou Junting Upgrades Its Testing Equipment to Strengthen Photoluminescent Material Quality Control

At Hangzhou Junting Luminescence Technology Co., Ltd., accurate testing is an essential part of developing reliable photoluminescent materials and maintaining consistent product quality. To further improve the precision of afterglow luminance testing and strengthen its overall quality management system, Hangzhou Junting has completed a comprehensive upgrade of its luminance testing equipment. The new equipment has now been officially introduced into laboratory testing and production quality-control processes, providing stronger technical support for the research, development, and final inspection of photoluminescent powders, self-luminous signs, and related products.

As photoluminescent materials are increasingly used in applications such as fire safety, transportation, and public infrastructure, reliable measurement of their luminous performance is particularly important. The brightness of a photoluminescent material changes continuously after it has been exposed to a light source. Being able to accurately measure this afterglow at different points in time allows manufacturers to better understand material performance, compare formulations, and maintain consistent production standards.

Improving the Precision of Afterglow Luminance Testing

The latest equipment upgrade at Hangzhou Junting focuses specifically on improving the operational performance and precision of afterglow luminance testing for photoluminescent materials. The new-generation luminance tester is equipped with a highly sensitive optical sensor probe designed to improve measurement capabilities in low-luminance ranges. This allows the equipment to accurately capture the afterglow luminance of a material at different time points following excitation.

Low-luminance measurement can be particularly important when evaluating the later stages of an afterglow decay curve. As the emitted light gradually decreases, accurate measurement becomes increasingly dependent on the sensitivity and stability of the testing equipment. The upgraded system is designed to reduce measurement deviations caused by environmental stray light while improving overall measurement stability. The equipment also provides more precise control over measurement accuracy, helping Hangzhou Junting maintain a more consistent testing process for its photoluminescent materials. The system is designed to meet relevant testing requirements associated with photoluminescent fire safety signage, providing an improved basis for both product development and quality control.

Standardizing the Excitation Process

Accurate luminance measurement depends not only on the measurement instrument itself but also on how the sample is excited before testing. To address this, the upgraded equipment incorporates a standardized excitation light source module. The intensity and exposure duration of the excitation light can be precisely set, allowing the sample excitation process to be standardized across different tests.

Standardization at this stage helps reduce variations caused by manual operation and makes it easier for researchers to compare results between different samples and formulations. Instead of relying heavily on individual operating procedures, the testing process can be carried out according to defined parameters.

For photoluminescent materials this consistency is particularly valuable during formulation development. When researchers adjust factors such as particle characteristics, material composition, or formulation ratios, even relatively small differences in testing conditions can affect the resulting measurements. A standardized excitation procedure provides a more reliable basis for evaluating those changes.

More Efficient Data Collection and Analysis

Another important improvement is the integration of an intelligent data acquisition system. The upgraded equipment can automatically record key parameters such as initial luminance and the subsequent afterglow decay curve. Testing data can be stored and exported, while report-generation functions make it easier to organize and review results.

The system also supports one-stop printing functions, further improving the efficiency of routine testing. This is particularly useful when developing and optimizing photoluminescent pigments and powders. A clear record of the luminance decay process can provide a more complete picture of material performance than a single measurement taken at one point in time.

Designed for Both Laboratory and Production Applications

The equipment upgrade is not limited to laboratory research. Its improved hardware structure and stronger resistance to interference allow it to support both long-term laboratory testing and quality-control inspections in production environments. The system has also been designed with a simplified human-machine interface.

This flexibility is important because photoluminescent material testing takes place at different stages of Junting's manufacturing process. Laboratory testing can support research and formulation development, while production testing helps verify that manufactured products continue to meet established internal quality requirements. By supporting both applications, the upgraded equipment provides a more integrated testing platform connecting research and development with production quality control.

Supporting More Consistent Photoluminescent Products

The luminance tester upgrade represents another step in Hangzhou Junting's ongoing efforts to strengthen its technical capabilities and product quality management. With more precise testing capabilities, the company can conduct more detailed adjustments to photoluminescent material formulations and establish more consistent luminance performance for its photoluminescent pigments and related products.

For Hangzhou Junting, investing in testing infrastructure is therefore closely connected to its broader approach to product development. Better measurement allows engineers and quality-control personnel to understand materials more precisely, identify differences between formulations, and maintain more consistent production standards.
