Characteristics of resin concrete drainage ditch
Resin concrete U - shaped drainage ditch is Changyi Chang Rong Machinery Co., Ltd. in 2006 to introduce foreign advanced drainage technology to produce a new generation of rainwater collection, emission products. A large number of products exported to Germany, Italy, Spain, New Zealand, the United States, Australia and other countries. The product Performance is far better than domestic at present commonly used cement drainage ditch, products have been successfully applied in 2008 Beijing Olympic Games bird's nest and water cube stadium hall.
Compressive and flexural strength
Resin mesh molecular structure, with the filler reaction can produce a strong bond capacity, so it has a very high compressive and flexural strength, the compressive strength of the special design can be as high as 2500kg/cm2
Anti - acid and alkali resistance of PH1---10. polyester resin concrete has better corrosion resistance, which is especially good for the corrosion resistance and resistance to acid soil.
Nonporous, non absorbent, all of the erosion, damage to both block outside, prevent biological in grow on the surface and destruction; let harmful organisms have no chance of survival. Ultra short time high concentrations of chemical corrosion, due to the high volume of aggregate filling, and no capillarity, destruction will only happen on the surface, not deep inside the concrete, destruction of structure strength.
The stability of the polymer with the specific heat of the polyester resin concrete is higher than that of the plastic resin material. Have a glass like stability. High strength, stability is good, in the domestic green environmental protection belong to the second class of materials; in the European Union, allows the recovery of the rolled gravel re-use, even directly as roadbed materials without environmental pollution problems.
Good weather resistance
Has good weather resistance, even in extremely poor conditions, there is still no phenomenon of brittle fracture or failure. Because of the stability of molecular structure, has good anti UV ability, not like the general engineering plastics because of ultraviolet radiation cause material aging, brittle fracture phenomenon. Freeze-thaw resistance, not afraid of cold damage, the use of safe areas in the alpine snow.
In the correct specification and installation, almost no limit design use fixed number of year, compared with the cement concrete, plastic and other materials, high life expectancy, the annual amortization cost is relatively low, so the use of resin concrete material is much higher than the economic benefits of other materials.
Light weight, precise size
Strength / weight ratio. The same specification strength of the products, can reduce the material thickness, can greatly reduce the weight of the finished product, so that the product is light weight. And reduce transportation, hoisting, excavation and other costs. Plastic, can be in a variety of different specifications of the size of a variety of accurate shape.
Easy processing, installation, adhesion
The experimental results show that the bending test is broken, and the bond is the bending, which is not broken by the original fracture. With the advantages of easy construction, easy installation, etc., for the control of the time limit for a great help. Processing is easy, can be carried out drilling, cutting, and other processing.
Smooth surface, maintenance free
Dense smooth surface, roughness coefficient n=0.010, hydraulic characteristics of good, easy accumulation of sediment, can reduce the frequency of maintenance. It can not be washed with high pressure water column regularly, and it is easy to remove sediment deposition, but it is not like cement concrete, it has the risk of damage, and the maintenance cost is saved.
Alternate freezing and thawing will reduce the cement performance, and influence of resin concrete is very small, because of resin concrete is no ceiling drainage hole structure, 1600 times freeze-thaw test did not happen with the quality and performance of the change.
Penetration resistance and water absorption
The water absorption rate of the resin concrete is below 0.1%. Smaller than wood and cement, permeability is 0.
Application range of U - shaped drainage groove of resin concrete
This product is widely used in foreign countries. Mainly used in municipal construction, such as: street drainage, square drainage, highway, airport, dock, park, yard, stadium, etc..
