The advantages of Synthetic resin roof tile must be well known to everyone. It is a new generation of environmentally friendly building materials that the country has vigorously promoted and advocated. Synthetic resin tile is environmentally friendly and energy-saving, and can be recycled. It has the advantages of light weight, convenient installation, thermal insulation, colorful, beautiful appearance, anti-aging, easy to fade, and long life. So, is there a drawback to such a popular product? Of course, any product has its advantages and disadvantages. What are the disadvantages of Synthetic resin roof tile?
1. Compared with color steel tile and ceramic tile, the impact resistance is slightly worse; due to the larger area of the resin tile, the connection position is not as beautiful as the color stone tile and ceramic tile.
2. The synthetic resin tile is pre-plasticized with ASA resin plus PVC resin at a high temperature of about 180 degrees. The product after cooling molding will deform at 70-80 degrees Celsius due to high temperature. Not suitable for factory housing in high temperature industries such as smelting and casting
3. The molecular structure of the polyvinyl chloride is between minus 30 degrees and 70 degrees Celsius, and the thermal expansion and contraction will occur due to the temperature contrast. Poor quality resin tiles, in the lower temperature areas, the pores in the middle of the resin tile will burst when it encounters snow water. Therefore, the synthetic resin tile is designed to control the spacing of the purlins from 66cm to 75cm, in order to prevent the synthetic resin tile from sagging or drumming due to thermal expansion and contraction, reducing the waterproof effect.
The reason why the synthetic resin tile has the above disadvantages is determined by its material. Compared with traditional roofing materials, the transportation and installation are troublesome, easy to fall off, and the service life is short. The resin tile is superior to the inferior. Some manufacturers use recycled materials to increase the hardness of the resin tile, but it will directly affect the toughness of the resin tile. If it is used for a long time, it will burst or deform. In order to ensure the quality of the products, WE XINGFA tile Industry considers the long-term use of the products and does not use recycled materials on the raw materials.
