High compressive and flexural strength
The resin's three-dimensional network molecular structure can generate strong bonding ability when reacting with fillers, so it has extremely high compressive and flexural strength. The compressive strength can be specially designed to reach 2500kg / cm2
Acid and alkali resistance
The acid and alkali resistance is as high as PH1 --- 10. Polyester resin concrete has strong corrosion resistance, and has excellent resistance to biological sulfuric acid erosion and acid soil.
No pores and no water absorption, all erosion and damage are blocked, which can prevent organisms from growing and destroying on its surface; it does not allow harmful organisms any chance of survival. For a short time, ultra-high concentration chemical corrosion, due to the high amount of aggregate filling, and no capillary phenomenon, damage will only occur on the surface, and will not penetrate into the concrete, destroying the structural strength.
Polyester resin concrete is more stable than thermoplastic resin materials after cementing. Glass-like stability. It has high strength and good environmental stability, and belongs to the second class of green and environmentally friendly materials in China. In the European Union, it is allowed to recycle rolled crushed stones for reuse, and even directly used as roadbed materials without environmental pollution.
Good weather resistance
With good weather resistance, even in extremely harsh environments, there will still be no brittleness or damage. Due to the stable molecular structure and good UV resistance, unlike ordinary engineering plastics, materials will age and become brittle due to UV rays. Freeze-thaw resistant, not afraid of cold, can be used safely in snowy areas in high mountains.
Under the correct specifications and installation, there is almost unlimited design service life. Compared with cement concrete, plastics and other materials, the service life is high and the annual amortization cost is relatively low. Therefore, the economic benefits of using resin concrete materials are much higher. For other materials.
Light weight and precise dimensions
Extreme strength / weight ratio. Products with the same specification strength can reduce the material thickness, greatly reduce the weight of the finished product, and make the product lighter. And reduce transportation, lifting, excavation and other costs. Strong plasticity, can make a variety of precise shapes according to different specifications.
Easy to process, install, and adhere
It has been proved by experiments that after the bending test is broken, the bond is subjected to bending and will not break from the original fracture; it is conducive to connection, and then, improves the overall water tightness. It has the advantages of easy construction and convenient installation, which greatly helps to control the construction period. It is easy to process and can be drilled, cut, etc.
Smooth surface and maintenance-free
The surface is smooth and dense, the roughness coefficient is n = 0.010, the hydraulic characteristics are good, it is not easy to deposit deposits, and the number of maintenance can be reduced. It can be flushed with high-pressure water column from time to time, and it is easier to remove sediment deposits, unlike cement concrete, which has the risk of damage and saves maintenance costs.
Alternating freeze-thaw will reduce the performance of the cement, but it has little effect on the resin concrete. Because there is no pore structure for water absorption and release in the resin concrete, the quality performance has not changed after 1600 freeze-thaw tests.
Impermeability and water absorption
The water absorption of resin concrete is below 0.1% by weight. Much smaller than wood and cement, with zero permeability.
Application range of resin concrete U-shaped drainage channel
This product is widely used in foreign countries. It is mainly used in municipal construction, such as street drainage, square drainage, highways, airports, terminals, parks, courtyards, stadiums, etc.
