Marine Ranch Salt-Alkali Resistant Materials
Category:
Marine Ranch Salt-Alkali Resistant Materials is the most widely used type of basalt fiber composite material. Although there is competition between glass fiber composite ribs and carbon fiber composite ribs, Marine Ranch Salt-Alkali Resistant Materials still has a place in the field of building applications due to its unique performance characteristics. Therefore, the editor still feels it is necessary to introduce the characteristics of basalt fiber composite ribs to you.
Marine Ranch Salt-Alkali Resistant Materials is a new type of non-metallic composite material made of basalt fiber as reinforcement material, synthetic resin as matrix material, pultrusion process and special surface treatment.Marine Ranch Salt-Alkali Resistant Materials has excellent physical and chemical properties such as high strength, light weight and corrosion resistance. At the same time, the thermal expansion coefficient of Marine Ranch Salt-Alkali Resistant Materials is similar to that of concrete, which ensures the synchronous deformation of concrete and reinforcement materials. In addition, since the material can be produced continuously in the longitudinal direction, the cement concrete used for continuous reinforcement can be configured according to the length of the road section, reducing the longitudinal welding process of reinforcement, greatly improving the progress of engineering construction, and has a wide range of engineering application prospects.
Core functions
Physical properties: 1. The density is 1.9-2.1g/cm³, which is only 1/4 of the steel bar, greatly reducing the deadweight of the structure. 2
.The thermal expansion coefficient is similar to that of concrete, ensuring coordinated deformation with concrete and reducing temperature stress cracks.
Mechanical properties: 1. The tensile strength is more than 3 times that of ordinary steel bars, and the elastic modulus matches that of concrete. 2 .
The significant continuous production characteristics simplify the construction process and are suitable for continuous reinforced concrete structures.
Chemical stability: 1. Excellent acid and alkali corrosion resistance, suitable for harsh environments such as humidity and salt spray, significantly extending the life of the structure. 2
. Non-conductive and non-magnetic, suitable for electromagnetically sensitive scenarios (such as medical facilities, communication base stations)
Advantages
1. Light weight, about 1/4 of ordinary steel bars;
2. Tensile strength is about 3-4 times that of ordinary steel bars;

Application Description:
1. Application in concrete bridge structure
inherit;">In the cold winter, a large amount of industrial nitrate is sprinkled on the bridge pavement every year to prevent ice formation, but salt water corrodes traditional reinforced concrete bridges severely. If combined ribs are used, the corrosion problem of bridges can be greatly reduced, maintenance costs can be reduced, and the service life of bridges can be increased. 2
、Application in road construction
In road construction, concrete pavement mainly uses edge steel bars, and prestressed concrete roads need to improve durability, because salting on the road in winter will aggravate the corrosion of steel bars. In order to solve the anti-corrosion problem, the use of combined ribs on the road shows great advantages.
3. Applied to structural concrete fields such as seaports, docks, coastal areas, and parking lots.
Whether it is a high-rise parking lot, a ground parking lot or an underground parking lot, there is a problem of winter antifreeze. The steel bars of many buildings in coastal areas have been significantly deteriorated due to the corrosion of sea salt in the sea breeze. The tensile strength and elastic modulus of black fiber composite bars are better than steel bars, and they are the best choice for reinforcement and reinforcement of underground projects. At the same time, tunnel concrete reinforcement, underground oil storage facilities, etc. are also widely used. 4.
Applied to anti-corrosion buildings.
Domestic sewage and industrial wastewater are the main sources of corrosion of steel bars, and other gaseous, solid and liquid chemicals can also cause corrosion of steel bars. Composite bars are more corrosion-resistant than steel bars, so they can be widely used in sewage treatment plants, wastewater treatment equipment, Shishan chemical equipment, etc.
5. Application in underground projects.
In underground projects, composite rib grids are usually used for reinforcement. 6
、Application in components in low conductivity and non-magnetic field environments.
Due to the electrical insulation and easy electromagnetic wave characteristics of the composite ribs, it is used in concrete buildings to prevent personal injury caused by current induction or short circuit, protect sensitive electronic communication equipment, etc., making full use of the non-magnetic and non-conductive properties of the composite ribs, and is widely used in medical insurance departments, airports, military facilities, communication buildings, anti-radar buildings, high-end office buildings, earthquake prediction observatories, electronic equipment rooms, etc. The use of Xuanwu composite reinforcement can also prevent electric shock accidents caused by current induction or leakage in buildings.
