Resin manhole cover is simply a manhole cover made of resin as the core composite material, which is a new type of environmental protection manhole cover. Due to its high degree of polymerization, high density, impact resistance, and tensile strength, it also has the advantages of wear resistance, corrosion resistance, no rust, no pollution, no maintenance, and so on. It has been widely used in fields such as landscape architecture of municipal buildings.
The use of resin manhole covers is the most common around us, but we all know that resin manhole covers are relatively new to most of us, and the common cast iron manhole covers around us.
Since the service life of cast iron manhole covers is not ideal, breakage and theft often occur, and most people still choose cast iron manhole covers; how much do you know about the service life of our resin manhole covers?
What is the service life of the resin manhole cover? The raw materials of the resin manhole cover are: unsaturated resin, glass fiber and other materials, and the steel frame.
I hope it will be helpful to everyone. Now the composite resin manhole cover has become a new material with a small recycling value. This solves the core problem of the resin manhole cover. So in this process, we can actively produce resin. Manhole covers are divided into two types: manhole cover bottom plate and manhole cover panel, which are then produced separately and combined into a whole.
In this process, we can make relevant provisions for the most practical functions of resin manhole covers, including technical aspects. Since we want to achieve these functions of the manhole cover, we should choose a new type of composite resin. Such a material has good toughness, and we will not use brittle materials in principle, because brittle materials are easily crushed by the car, which will cause cracking At the same time, the water vapor in the well will also evaporate accordingly. The cracking material we use will be absorbed, and after the material absorbs moisture, it will be hydrolyzed, so the service life of the product will be greatly reduced.
