Summer arrived, how does PVC soft door curtain prevent ageing?

It’s getting hotter and hotter, and it’s almost summer, and girls are already wearing sunscreen to protect their skin from the sun’s harmful rays. Similarly, for most manufacturers, it is necessary to prepare for a rainy day, on their own products to protect, just like their own, today we talk about how to protect the soft curtain. PVC soft door curtain is a product that everyone can see everywhere. With the development of society, various kinds of transparent PVC door curtain have appeared, such as: transparent PVC plastic door shade, insect-proof door shade, dust-proof door shade, anti-static door shade, cold-proof door shade, low temperature-proof door shade, anti-ultraviolet ray door shade, transparent PVC soft board, automatic quick roll door, quick roll door, PVC dust-proof door shade, PVC soft rubber shade, transparent soft door shade, anti-static grid shade, plastic PVC rubber shade, PVC plastic door shade, plastic transparent door shade, etc. . The transparent soft door curtain made of PVC keeps cold, keeps warm, saves energy and insulates cold and hot air. Insect, dust, wind, moisture, fire, static electricity, anti-glare, anti-uv, sound insulation, daylighting, safety warning, prevent accidents. Applicable to cold storage, food, chemical, pharmaceutical, textile, electronics, machinery, printing, factories, workshops, hospitals, markets, restaurants and other industries any place. You could say it has a wide range of applications.

So how do we keep the door curtain from yellowing and discoloration for a long time? We need to know the cause of its yellowing. Research shows that the aging of polymers in the atmospheric environment is mainly due to the photooxidation degradation of polymers by ultraviolet radiation and with the participation of oxygen, pvc Curtain, wire and cable, agricultural film and other outdoor products should pay more attention. According to quantum mechanics, the energy of a single photon is inversely proportional to the wavelength, and the shorter the wavelength, the higher the energy. Although the intensity of ultraviolet ray only accounts for 5% of sunlight, its wavelength is the shortest, and the single photon energy is the highest, about 290 ~ 390 KJ/MOL. The bond energy of the compound is usually 290 ~ 400 Kj/mol, which is close to the energy of ultraviolet ray and is easily destroyed by ultraviolet ray, this is the main reason that PVC curtain is easy to produce photoaging. During the aging process, free radical and hydroperoxide are produced, macromolecule chain is broken and cross-linked, and finally the product loses its performance.

Uv Absorber can effectively inhibit the damage of UV to products, so as to reduce the degree of product deterioration and extend the service life of polymers. A LR-ZW-1 developed by Henan Longrui Chemical Co. , Ltd. can strongly absorb 270 ~ 400nm UV, the absorbed energy is released or consumed as heat energy or harmless low energy radiation, so as to prevent the UV energy absorbed by the Chromophore of the PVC curtain from being excited. Extend the service life of the curtain, late not easy yellowing, also do not affect the transparency, the most important is to add a small amount, saving the cost of manufacturers.
