u003cbru003eu003cpu003e What factors affect the service life of PC solar panels? As a building decoration material, the service life of PC polycarbonate sheet is undoubtedly an issue that everyone cares about. There are many products on the market that guarantee the service life, but what is the quality guarantee of the sunshine board? What is the service life of the sun board? u003c/pu003eu003cpu003e 1. What is the service life of the polycarbonate sheet? PC sunshine board is produced from polycarbonate raw materials. As a polymer material, the important factor related to its service life is ultraviolet light. Ultraviolet rays in nature can chemically degrade polymer materials, which is generally called aging. Therefore, the problem of ultraviolet rays can be solved to talk about the length of life. u003c/pu003eu003cpu003e 2. How to understand aging? The sign of aging is that the originally translucent solar panels appear dirty, the light transmittance decreases, and the color becomes yellow during use; the inherent manifestation of aging is the decline in physical properties, loss of the originally relatively high impact strength and tensile strength, and change It's easy to break. The fake and inferior solar panels that we often see, after a period of use, the transparency becomes very poor, some begin to crack, and even become crispy, which are all signs of aging. To delay the aging time, that is, to extend the service life, the choice of good raw materials is fundamental. u003c/pu003eu003c/pu003eu003cpu003e 3. How does the sun panel solve the problem of ultraviolet rays? First, use the special extrusion-grade polycarbonate material of the polycarbonate sheet, which has a certain anti-aging performance; at the same time, the sunshine board co-extrudes the ultraviolet protection layer on-line while the main equipment extrudes the sheet, which is close to the base layer of the sunshine board Combine. This UV protection layer can cut off 99.99% of UV rays, making the sheet itself protected from UV rays. In addition, because of the advanced process of online co-extrusion, the UV protection layer of the solar panel will not be delamination and peeling off, and the imported anti-uv UV absorber is used, and the performance is more stable. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e 4. What are the key quality points of the UV protection layer of the sun panel? The thickness of the UV protection layer of the sun board is, if understood, it is many times thinner than the hair. How can it be evenly squeezed out to a width of two meters? The first is to ensure the use of imported special-purpose solar panel production lines for the solar panels, and the second is the control during the production process. The quality control department of the solar panels conducts online sampling every few hours and detects 40 points in the width direction with a professional Zeiss microscope. Detect the thickness of the UV protection layer to control the stability of the thickness. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e 5. Can the UV protection layer of the sun panel be seen by the naked eye? Due to the thickness, the ultraviolet protection layer of Hebei Hongsheng is not visible to the naked eye. There are some methods such as observing the color of the fault, which is not very scientific. Accurate detection methods require special testing equipment, which is equipped in the production plant of Hebei Hongsheng . u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eu003c/pu003eu003cpu003e
