Plastic dowel in sleeper manufacturers said that many people want to know how to use railway studs to prevent corrosion. Let's take a look today.
1. Use non-sulfur anchoring materials for anchoring:
We choose pure silicate 525 white cement with hydraulic gel material as cementing material and emery as a new water-soluble anchoring agent for orthopaedics, in which a certain amount of rust inhibitor is added. The plastic dowel in sleeper manufacturer tells you that you only need to mix the various materials and water in the formula to use it evenly, which can achieve the anti-corrosion purpose of the screw spike while the pullout resistance is not less than 60KN.
2. Coating with long-lasting anti-corrosion grease:
Plastic dowel in sleeper manufacturers tell you that road studs will be subjected to axial vibration and radial torsion under conditions of severe cold, high temperature, rain, sand and corrosive media such as 0₂, S₂, C1₂, etc. for a long time. Ordinary anti-corrosion grease is far If the anti-corrosion needs cannot be met, solid fillers, antioxidants and metal deactivators, anti-corrosion and anti-rust agents, etc. should be added to improve and improve the anti-rust and water-spray properties of the anti-corrosion agent to meet the different requirements of protection.
3. Standardize the anchoring process:
The manufacturer of Plastic dowel in sleeper tells you that when using non-sulfur anchoring agent for screw bolt anchoring, you need to use the anchor frame as required to ensure the accurate position of the road stud. When anchoring, the nail holes should also be cleaned up, the solution should be filled at one time, and it should not be too full or too little. After anchoring, the round table of the screw spike should be 0-2mm higher than the sleeper rail support table (when using elastic fasteners), The nail hole should be fully filled. After the anchoring solution is condensed, a flat shovel should be used to clean up the spilled anchoring agent, and the plane around the spike hole should be trimmed to avoid the unevenness, which is easy to cause moisture to stay and cause corrosion on the round table of the spike.
