1.Description:

Porcelain is a semi-transparent product, and the quality of its transparency is one of the important indicators for evaluating the quality of the porcelain. White, smooth, and highly transparent porcelain gives a bright and clear impression, and is therefore loved. Transparency not only shows the visual characteristics of the porcelain's appearance, but also reflects its internal physical and chemical properties. Transparency is closely related to the mineral composition of the porcelain body, crystal shape, chemical composition, particle size, the number of pores, and the degree of firing. By using the transparency index, one can determine the content of liquid phase (glass phase) inside the device, compare the uniformity of different parts of the same device, and assist in determining the firing temperature range of the product. Therefore, the measurement of transparency is of great significance for identifying the quality of porcelain and for scientific research in the ceramic industry.
The 77C-1 type porcelain body light transmittance instrument developed by our company is a specialized instrument for measuring the light transmittance of ceramics. It is particularly suitable for use in research institutions, colleges and universities, as well as the central laboratory of relevant production factories in the ceramic industry.
2.Structural principle
The 77C-1 transmittance meter is an all-in-one cabinet-type instrument. It has a novel design, compact structure, and light weight. It can directly take porcelain sample specimens for testing, read the results directly, and is easy to operate. It features high sensitivity and good stability.
The 77C-1 transmittance meter is composed of a stabilized power supply, a photoelectric conversion mechanism and a digital galvanometer.
