Studies have shown that human hearing can accept a maximum volume of 30 decibels. When the continuous indoor noise pollution exceeds 30 decibels, normal sleep will be disturbed, and living continuously in a noise environment of 70 decibels or more, human hearing as well as physical health will be affected.
Glass is a poor conductor of heat, not easy to conduct heat, so the windows inside the home using glass material, can play a thermal insulation effect, including the cotton clothes we wear in winter, are poor conductors of heat, so as to keep warm. And cooking with iron pots and pans and other metal products is a good conductor of heat, good thermal conductivity.
1. What is visible light transmission rate? The percentage of light intensity that passes through glass in the visible spectrum (380nm to 780nm). 2. What is visible light reflectance? The percentage of light intensity reflected by glass in the visible spectrum (380nm to 780nm).
ultra-clear glass, also known as high transparency glass and low iron glass, is an ultra-clear low iron glass. How high is its light transmittance? The light transmission rate of ultra-white glass can reach 91.5% or more, with the characteristics of high-grade and elegant, crystal clear. Therefore, it is called the "crystal prince" of the glass family, and super white glass has superior mechanical, physical and optical properties, which is unparalleled by other glasses, while super white glass has all the processable properties of high-quality float glass, so it can be processed like other float glass. This superior product performance and quality makes ultra-white glass has a broad application space and advanced market prospects.
Hi! Have you ever bumped into a glass door? Many people have bumped into it, sometimes because the store's glass window wipe too clean, and the lack of obvious enough signs, but also make some customers hit. Because when you walk from a darker environment to a relatively bright area, it is not easy to find the middle of the blocked glass, it is most likely a very painful experience.
