Weathering steel, i.e. atmospheric corrosion-resistant steel(Corten Steel), is a series of low-alloy steel between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of toughness, plasticity, forming, welding and cutting, abrasion, high temperature and fatigue resistance of high-quality steel. The weathering resistance is 2-8 times of ordinary carbon steel and the coating performance is 1.5-10 times of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used in railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other steel structures exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipme.

Talking about the solar insecticidal lamp used by fruit farmers in Tex County, Xinjiang
On June 24th, Xinjiang Tex County Agricultural Technology Promotion Center issued 8 sets of solar insecticidal lamps for the county's Liangfan field free of charge. The prevention and control area of ​​each unit is 20-25 mu, which has been well received by technicians on-site guidance and trial. The insecticidal effect is generally welcomed by fruit farmers. Liangfanchang is the main apple production base in Tex County. The large number of apples produced each year is sold to large and medium-sized cities in the Mainland while satisfying the county. With the concept of green pollution-free agricultural products (000061, stocks) deep in the hearts of people, the quality requirements for apples are getting higher and higher, in order to further improve the quality of apples in the county, and reduce the impact of pests on apples. The solar insecticidal lamp is a physical insecticidal device specially designed according to the phototaxis of insects. The light wave emitted by the light source has strong insect attracting characteristics. In this way, the insect pests are trapped, and the types of pests are large and large, and the number of insect pests can be large. The amplitude reduces the amount of insects dropping eggs, and reduces the number and density of insect populations, and the effect is remarkable. At the same time, it can protect the natural enemies of pests, continue the occurrence of pest resistance, and is harmless to humans and animals. Moreover, solar insecticidal lamps are low in cost, arbitrarily versatile, and easy to move, and can be placed wherever needed. Through the promotion and use of solar insecticidal lamps, the use of pesticides is reduced, the pollution of agricultural environment is reduced, and the ecological balance is maintained.
