Brief introduction and characteristic analysis of PVC film as thermal insulation material
polyvinyl chloride (PVC) The film is made of polyvinyl chloride resin as the main raw material and a proper amount of plasticizer (Increase its flexibility) At the same time, many products also add light stabilizers and ultraviolet absorbers to improve weather resistance and heat resistance, and add surfactants to improve anti-fog effect. Therefore, polyvinyl chloride films have various types and rich functions, at present, it has become one of the most commonly used films in Japan and China.
polyvinyl chloride films are divided into transparent films and pink films. Most of the processing processes are treated with dust and anti-fog drops, so that water can flow down in a film shape. Polyvinyl chloride films not only have good flexibility, transparency, heat preservation and anti-fog drop effect, but also some films have light selection and strong heat preservation functions. The disadvantage of PVC film is that it is prone to slow release of plasticizer and dust absorption, which makes the light transmittance of PVC film drop rapidly and shortens its service life. At present, there are many so-called light conversion films on the market, most of which are ultraviolet-removing films produced in recent years, and the ultraviolet transmittance is changed by adding ultraviolet absorbers to polyvinyl chloride raw materials.
as mentioned above, controlling the ultraviolet transmittance can not only promote the growth of some plants, but also reduce the occurrence of leaf mold, Sclerotinia sclerotiorum and some pests, however, it must be used cautiously in some crops. The thermal insulation is related to the transmittance of the film to the long-wave radiation area. The transmittance of polyvinyl chloride film to the long-wave radiation is significantly lower than that of polyethylene film and EVA film. Therefore, its thermal insulation is also better than polyethylene film and EVA film.
