The coming of summer has also brought frequent rains. In many places in the country, there has been a heavy rain.
Rainwater can also cause many hazards as well as sweltering heat and bring vitality. Flood control pressures increase sharply, and the incidence of secondary disasters such as landslides and mudslides increases.
Flood control measures are projects that are highly valued by local governments. Water conservancy projects are used to intercept and regulate floods, reduce flood peaks or flood diversion, etc., in order to achieve flood control and reduce losses.
One of the effective measures to improve the defense capacity of river embankments is to add some fibers to the concrete during the construction of the project, to construct dams, reservoirs and canals for water conservancy projects; for pavement and bridge decking of road and bridge works; The pier, flood control, etc. have better effects.
In order to enhance the building, the way in which fibers are incorporated into concrete has been around for a long time.
In 1965, Goldfein proposed and used polypropylene fiber for the explosion-proof structure of the US Army Corps of Engineers; in the late 1960s, the United States and Europe began to use polypropylene fiber concrete for cement products and construction. Since the 1980s, the United States and Europe have developed high-strength, high-elastic modified fibers for reinforcing concrete. The amount of fiber reinforced concrete has accounted for more than 10% of the total amount of concrete, and more applications are polypropylene, vinylon, nylon and the like.
China first conducted polypropylene fiber research in the 1980s. In recent years, a number of concrete fibers represented by polypropylene fibers have been developed in China to prevent the occurrence and development of primary cracks in concrete, eliminate or reduce the number and scale of primary micro-cracks, improve the anti-cracking and impermeability of concrete, and improve concrete. Resilience and other aspects have played a very important role.
As a professional company engaged in the research and development of all kinds of engineering fibers, high-strength polypropylene filament, high-strength double-twisted polypropylene filament and integrated line, Silk Silk is a leading enterprise in the Jiangsu coastal engineering fiber industry cluster, a private technology enterprise in Jiangsu Province. National High-Tech Enterprise.
The "Silk Edge" brand polypropylene fiber produced by Silk Wire has strong mechanical properties, good physical properties and wide application range. With excellent quality, it has passed ISO9001: 2000 international quality management system certification and became a famous brand in China.
Summer disasters hit, "silk edge" polypropylene fiber, improve the "protective power" of engineering facilities!
Polypropylene fiber enhances protection!
