First, PVC raincoat material introduction:

After the PVC is mixed with the additive and plasticized, a transparent or colored film of a predetermined thickness is formed by a three-roll or four-roll calender, and the film is processed in this way to become a calendered film. It can also be processed by shrinking, heat sealing bags, raincoats, tablecloths, curtains, inflatable toys, etc. Wide transparent film for greenhouses, plastic greenhouses and mulch. The biaxially stretched film, which is subjected to heat shrinkage, can be used for shrink packaging.

Second, the advantages:

1. Lightweight: The reason why the tension structure has a small weight is that it relies on the prestressed form rather than the material to maintain the stability of the structure. Therefore, its self-weight is much smaller than the traditional building structure, but it has good stability. Architects can use their light and large span to design and organize structural details to unify their light and stable structural characteristics.

2. The transparency of the film is determined by its base fiber, coating and its color. The spectral transmittance of standard membranes is between 10% and 20%, and the spectral transmittance of some membranes can reach 40%, while some membranes are opaque. The light transmission of the film and the choice of light color can be adjusted by the color of the coating or the color of the top layer.

3, light transmission: light transmission is one of the most widely recognized characteristics of modern membrane structure. The light transmission of the film can provide the required illumination for the building, which is very important for building energy saving. It is especially important for some commercial buildings that require more light and high brightness. Through the comprehensive utilization of natural lighting and artificial lighting, the transparency of the film can provide a larger aesthetic creation space for architectural design. At night, light transmission transforms the membrane structure into a sculpture of light.

4. The multilayer film containing the heat insulating layer can be made translucent by appropriate combination of the film material and the light-transmitting heat insulating material. Even if the spectral transmission is only a few percent, the film roof is still shiny and translucent to the human eye, with a light roofing look.
