The hydraulic prop adopts advanced technology to carry out special surface treatment technology, so that the prop has the characteristics of anti-corrosion, abrasion resistance and anti-blasting. The working medium uses the underground neutral water of the coal mine, which ensures that the working environment and groundwater are not polluted and that It not only improves the quality of drinking water in the mining area, but also ensures the health of people living in the mining area. It is an ideal environmental protection product for coal mining face support.
Hydraulic Prop Surface After Special Treatment Technology
The hydraulic prop adopts the domestic advanced EDA anticorrosive technology, which doubles the anticorrosive ability of the surface of the living cylinder. In use, even if the surface of the living cylinder is punctured or severely bumped, exposing the substrate will not cause large-area corrosion of the substrate or peeling of the coating.
Using zinc nickel, the surface is green-passivated and coated with silicone, its anti-corrosion ability is more than three times that of galvanizing and phosphating process. Due to the use of zinc-nickel composite coating, the potential difference between the active base prop and the coating is reduced, which is not easy to form. The primary battery, when the coating is damaged by impact, produces self-protection ability, which is suitable for use in blasting working faces.
