1, Product Features
1. Strong anti-corrosion performance: Mining galvanized anti-corrosion anchor cables are treated with galvanizing to form a dense zinc layer on the surface of the anchor cable, effectively preventing corrosive media such as water, oxygen, chloride, etc. from contacting the anchor cable substrate, thereby protecting the anchor cable from corrosion. At the same time, the anti-corrosion layer (such as epoxy resin coating) further enhances the chemical resistance of the anchor cable, ensuring its stable performance even in harsh environments such as humidity and water immersion.
2. High strength: Galvanized anti-corrosion anchor cables for mining are usually composed of high-strength steel strands or cables, which have extremely high tensile strength and stability, and can withstand high tension, heavy load, and harsh working conditions in mining environments.
3. Good durability: Galvanized anti-corrosion treatment improves the durability of anchor cables, extends their service life, and reduces replacement and maintenance costs caused by corrosion.
4. Convenient construction: The construction of galvanized anti-corrosion anchor cables for mining is similar to that of ordinary resin anchor cables, with no reduction in anchoring force and a relatively simple and fast installation process.
2, Technical parameters
The technical parameters of galvanized anti-corrosion anchor cables for mining may vary depending on the specific product and manufacturer, but generally include the following:
Nominal diameter: Models such as SKP22-1/1770 (F) and SKP22-1/1860 (F) indicate the diameter and strength grade of the anchor cable.
Breaking strength: Refers to the maximum tensile force that the anchor cable can withstand before breaking, such as ≥ 1770 MPa or ≥ 1860 MPa.
Breaking force: Refers to the specific tensile force that the anchor cable can withstand before breaking, such as ≥ 504 kN or ≥ 530 kN.
Yield strength: Refers to the maximum tensile force that an anchor cable can withstand before yielding, usually similar to its breaking strength.
Drilling diameter: Refers to the range of diameters required for drilling holes when installing anchor cables, such as 28-30 mm.
Elongation rate: Refers to the elongation rate of the anchor cable under stress, such as ≥ 5%.
Resistance value of anti-corrosion coating: indicates the insulation performance of the anti-corrosion coating, such as 106 Ω.
Burning grade of anti-corrosion coating: indicates the flame retardant performance of the anti-corrosion coating, usually the flame retardant grade.
