The reason for the aging of plastic film shed
Jun 22, 2017

The aging of plastic greenhouse membrane is one of the main reasons for the deterioration of greenhouse membrane, according to plastic greenhouse membrane manufacturers to introduce the main reason for the aging of greenhouse membrane is oxidation. Below to learn more about the details. First, many polymers in processing, storage phase of the use of oxidation, especially in the field of long-term heat and light irradiation, but also accelerated oxidation, resulting in polymer molecular fracture, degradation, resulting in plastic greenhouse membrane aging, loss of strength, loss of use value. Another culprit for the aging of plastic greenhouses is ultraviolet radiation; the light in the sun's 2.9014 million NM is ultraviolet, its radiation can destroy the carbon hydrogen ingot in the polymer molecule, causing the degradation of the polymer, which leads to the decrease of mechanical properties.
