Spheroidal graphite is obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the ductility and toughness, so that the strength is higher than that of carbon steel. Ductile iron is a kind of high strength cast iron material developed in the 1950s, its comprehensive performance is close to steel, it is based on its excellent performance, has been successfully used to cast some complex forces, strength, toughness, wear resistance requirements of high parts. Ductile iron has rapidly developed into a cast iron material second only to gray iron and widely used. The so-called "iron instead of steel" mainly refers to ductile iron.
Using polymer as matrix material, adding reinforcement material, filler, etc., through a certain process of composite inspection manhole cover. The new national standard has increased the load requirements of the manhole cover and is in line with the internationally accepted EN124 standard.
Fiber reinforced thermosetting composite material with unsaturated polyester resin as matrix, also known as DMC, is a new type of environmental protection cover plate made by pressing molding technology. Composite manhole cover adopts high temperature and high pressure one-time molding technology, high polymerization degree, high density, good impact resistance and tensile strength, with wear resistance, corrosion resistance, no rust, no pollution, maintenance-free and other advantages.
