PVDF membrane material for train station and light rail station
I.Features of PVDF membrane:
1. Self-cleaning performance The bonding strength between PVDF self-cleaning coating and PVC bottom layer and the reliability of finished film processing and welding, add a primer coating layer between the PVDF self-cleaning layer and the PVC bottom layer. It not only solves the poor self-cleaning problems of PVC film material, the plastic agent easily moves to the surface of the material and adheres to the air, and the dirt in the rainwater is not easy to clean, but also improves largely durability;
2. Optical performance The film material can filter out most ultraviolet rays and prevent internal elements from fading. Its transmittance to natural light can reach 25%. The transmitted light produces a uniform diffuse light within the structure, without shadows, without glare and with good color rendering. Under the combined action of ambient light and internal lighting at night, the membrane structure The surface emits a natural and soft glow, which is intoxicating;
3. Fire behavior Today, widely used membrane materials can meet the demand for fire protection, have excellent fire and high temperature resistance, and meet the standards of France, Germany, the United States, Japan and other countries. . ;
4. Good thermal insulation The thermal insulation performance of single-layer membrane material is the same as that of brick walls and better than glass. As with buildings made of other materials, the internal temperature of membrane buildings can also be adjusted in other ways. For example: add a layer of insulation inside, use air conditioning heating equipment, etc.;
5. Mechanical properties PVDF is a translucent polymer with 59% fluorine content. It has high impact resistance, abrasion resistance, creep resistance, and good toughness. It is the strongest among the fluoroplastics.
II. What is PVDF membrane material:
PVDF membrane material is a kind of high strength flexible film material. It is a material that is woven into a fabric substrate from fibers, and then processed and fixed with resin as a covering material on both sides of the substrate. The fabric substrate in the center of the film is divided into two types: polyester fiber and fiberglass, and the resin used as the coating is polyvinyl chloride (PVC) resin. In terms of physical and mechanical properties, the fabric substrate and coating have the following functions:
1. Cloth substrate: tensile strength, tear resistance, heat resistance, durability, fire resistance, etc.
2. Coating materials: weather resistance, antifouling, processability, water resistance, light transmittance, etc.
