Analysis of physical property changes in films due to UV irradiation

Investigating how the light transmittance of blue light cut film changes using a spectrophotometer!

The blue light cut film has the effect of suppressing the transmission of visible light, especially light with wavelengths below 500nm, compared to regular PET film. Using a spectrophotometer, we examined how the light transmission properties of the blue light cut film change under UV irradiation. The transmission of light in the wavelength range of 350 to 400nm further decreased due to UV irradiation. Additionally, we conducted an analysis of the reactions occurring within the film using GC-MS.

We are explaining the changes in transmittance of PET resin and PVC resin using graphs!

Introducing the "Transmittance Measurement Service Using an Automatic Spectrophotometer." The transmittance of transparent materials is an important characteristic item in the specifications of the products used. This characteristic may deteriorate or be lost due to degradation from heat, humidity, ultraviolet light, and other factors. This document includes the principles of the equipment, as well as a comparative evaluation of the changes in transmittance before and after constant temperature and humidity testing of transparent resins, along with discussions on the results. We encourage you to read it.

Here is an example of analyzing the polymer components and additives used in PTP packaging sheets for tablet packaging!

This document introduces the analysis of PTP packaging sheets using EGA-MS analysis and thermal desorption/pyrolysis GC-MS analysis. Various materials are used in industrial products; for example, polymers contain low molecular weight components such as additives and high molecular weight components that are the polymers themselves. In GCMS analysis, low molecular weight components volatilize at relatively low temperatures, while high molecular weight components need to be decomposed at high temperatures before analysis. Here, we present an example of analyzing the polymer and additive components of PTP packaging sheets used for tablets. We invite you to read it.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
