After summarizing the advantages and disadvantages of various composite material manhole cover technologies, Chenhang Polymer Anti-theft Art Manhole Cover makes the product unique through material innovation, structure innovation and design innovation
Structural Innovation
Chenhang High Molecular anti-theft art manhole covers adopt a pot bottom structure, which makes the force-bearing area more than ten times to dozens of times larger than the flat plate and ribbed type. The entire structural layer of the manhole cover is laid with continuous glass fibers, which can bear the force evenly. Therefore, the structure makes the product have a stronger bearing capacity.
Two material innovations
The surface of the Chenhang polymer anti-theft art manhole cover is filled with quartz sand, which has high hardness, and anti-aging agents such as ultraviolet absorbers are added to the surface to make it wear-resistant and usable. Lifespan is doubled. And because it does not use steel bars as reinforcing materials but uses continuous glass fibers as reinforcing materials, it avoids the separation and falling off phenomenon that occurs in other composite products due to the use of other reinforcing materials. All of them not only meet the requirements of the load-bearing capacity of the manhole cover, but also ensure the long-term stability and reliability of the intrinsic quality of the material.
Three process innovations
Different reinforcing materials are used according to different parts of the manhole cover. Quartz sand particles are used as filling materials in the surface layer. It has good wear resistance and ultraviolet absorbers are added to improve the aging resistance of the manhole cover. The structural layer can give full play to the characteristics of continuous fibers, so that the manhole cover does not contain any steel bars and has higher bearing capacity and longer service life, making it more competitive in the market.
Four design innovations
According to the individual needs of users, the graphics, text, relief art and color art are integrated into one, and are applied on the surface of the manhole cover to achieve an artistic effect and uniqueness, thereby enhancing the culture of the overall project. grade.
