Characteristics of the Resin Manhole Cover?

Characteristics of the Resin Manhole Cover?

The new building materials industry standard of the People's Republic of China (standard number: JC889-2010) steel fiber, concrete, inspection manhole cover is divided into four levels according to bearing capacity.

     A. Special passages and venues for airports or highways for helicopter take-off and landing.

     B. Urban roads, roads and parking lots used for motor vehicles to park.

     C. For slow lanes, residential residential passages and sidewalks.

     D. For the green belt motor vehicles can not drive, parked communities and venues.
1. Strong anti-permeability: The resin Composite Manhole Cover is made of non-filled resin glass fiber and other steel skeletons, which are compounded by special production process. After high temperature molding, the material has no recycling value. Take out the reinforcement and the cost exceeds the value of the reinforcement. Therefore, it has the function of active anti-theft.
2. Large bearing capacity: The bottom adopts a special pot bottom structure, which is a dozen times of the force area increased, so that the continuous reinforcing fiber yarn is used to ensure the integration of the fiber and the glass fiber. This allows the product to have sufficient carrying capacity and meet or exceed national standards.
3. Long service life: By using high-performance resin, fiber and special production and distribution, the penetration of resin in glass fiber is ensured, which greatly increases the adhesion of the two.
4. The polymer molded manhole cover produced by our company adopts BMC/SMC resin, quartz sand heavy calcium and other high load (50KN-900KN) materials, plus steel frame, and is molded by high temperature and high pressure once. The product has the advantages of high density, high hardness, high pressure, light weight, corrosion resistance, anti-aging, beautiful appearance, artistic pattern or cell unit name.
It has been tested by the national authority and weighed 54 tons. All the indicators exceeded the national standards. The products were sold to all parts of the country and exported in large quantities. It is an ideal substitute for cast iron manhole cover and cement manhole cover.
The Resin Manhole Cover has the advantages of light weight, high strength, excellent fatigue resistance, breakage safety, simple molding, low noise of car rolling, good chemical corrosion resistance, good acid and alkali resistance and beautiful appearance. Its comprehensive performance and economic indicators have surpassed the cast iron manhole cover, and it can also solve the problem of the theft of the cast iron manhole cover. At the same time, it can reduce the consumption of resources and has important economic and social values, which are manifested in:
1. Strong anti-theft performance: The resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and steel frame by special production process. After high temperature grinding and molding, the material has no recycling value. It is very difficult to take out the steel bar. The cost exceeds the value of the steel bar) and therefore has the function of active anti-theft.
2. Large bearing capacity: The bottom of the bottom adopts a special pot bottom structure, which increases the force area by a dozen times or even dozens of times. The continuous reinforcing fiber yarn used ensures the fiber filament and the glass fiber cloth together in a material, so that the product has sufficient carrying capacity. And meet or exceed the standard.
3. Long service life: By using high-performance resin, glass fiber and special production process formula, the penetration of resin in glass fiber is ensured, and the adhesion between the two is greatly enhanced, so that the material does not under the cyclic load. Internal damage is created to ensure the longevity of the product and the superiority of other resin composite well covers. Eliminate the disadvantages of poor adhesion.
4. Beautiful and practical, high grade: According to the needs of high-end customers, we can make complex LOGO and multi-color personalized design on the same manhole cover surface, making the pattern delicate, colorful and distinct. According to the customer's requirements, we can make all kinds of imitation stone surfaces and colors that are the same as various stone pavements.
5. High temperature resistance/low temperature, good insulation performance and strong corrosion resistance: the product is corrosion resistant, non-toxic and harmless. No metal additives, it has a real insulation effect. It can be used in places that are complex, varied, and demanding. The products have been tested by relevant authoritative testing institutions, and have obvious acid and alkali resistance, corrosion resistance, and many indicators such as anti-aging have reached and exceeded the standard.

Anti-theft manhole cover
6. Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and reverse phenomenon after the car is crushed. At the same time, due to the light weight of the product, the cover and the seat are fastened, which overcomes the problems of “jumping, smashing, ringing, shifting” of other inspection manhole covers.
 With the GB/T23858-2009 inspection manhole cover standard promulgated by the state in 2009, the new product quality standard has improved the load requirements of the manhole cover and is in line with the internationally accepted EN124 standard. After the implementation of the standard from February 1, 2010, the composite manhole cover was identified as a type of inspection manhole cover, and its characteristics were described: using a polymer as a matrix material, adding a reinforcing material, a filler, etc., and compounding through a certain process. The popularity and application of the inspection manhole cover in the market. The polymer composite cover has the advantages of light weight, high strength, good fatigue resistance, good breakage safety, excellent molding process, low noise, no corrosion, acid and alkali resistance, and beautiful appearance. It is an ideal substitute for cast iron manhole cover.
