What about the key points for selecting flour mesh?...

The nylon mesh has the advantages of repeated cleaning, long durability, corrosion resistance and the like. Being used in the desert is also a big help.

In China, the economic loss of land desertification including desertification is about 470 billion yuan. Under the existing technical, economic and natural environmental conditions, the desertified land that can be treated in recent decades is about 500,000 km2. According to the National Ecological Environment Construction Plan promulgated by the State Council in 1998, in terms of desertification control, the short-term goal (2010) is 220,000 km2, and the medium-term target (2030) is 400,000 km2.

The most serious and concentrated area of ​​the desert is the northwest. The degradation of the ecological environment not only endangers the survival and development of local people, increases the level of poverty, but also poses a serious threat to China's ecological security and socio-economic development, and adversely affects China's international image. Therefore, preventing desertification and curbing the deterioration of the ecological environment has become an insurmountable obstacle to the survival and development of the arid regions in the northwest.

The use of nylon mesh for sand barriers is the most economical and environmentally friendly. Nylon mesh has the characteristics of high toughness, good elasticity, corrosion resistance, oil resistance, water resistance, wear resistance, high temperature resistance, weather resistance, etc. It also has good 

insulation properties and low lubrication coefficient. It is especially important for sand control and sand fixation in the national desert. And economic and environmental protection.

The specifications of nylon woven mesh are mainly mesh, wire diameter, aperture, width, etc. Nylon meshs have different specifications and different uses, so the specifications are not the same. Generally, the number of meshes used for screening and filtering is 60mesh-420 mesh, there is a corresponding ratio parameter between the wire diameter and the mesh.

Nylon mesh can be used not only for sand protection, but also for printing and filtration. Just the number of meshes is different.
