How To Remove Rust From Railroad Spikes

How to Protect Railroad Spike from corrosion

As an important component of railway, railroad is used to spike the rail and base plate to railroad tie. Some factors will make railroad spikes easy to endure corrosion, including long-term apply; with prolong air exposure, rain and wastewater erosion. How to protect railroad spikes from corrosion? As a professional person manufacturer of railroad spikes, AGICO RAIL volition introduce the style to protect railroad from corrosion in 4 steps: choice of railroad spikes, option of railroad spikes anchoring amanuensis, coating anti-corrosive grease and standardize anchoring technology.

Choice of railroad spikes

Earlier using new railroad spikes or irresolute broken railroad spikes, selecting alloying or nitrocarburized railroad spikes to against corrosion. As well, good railroad spikes have anticorrosion sleeve betwixt the beginning thread part and the second part. And then, the effective method for protect railroad spikes from corrosion is selecting the anticorrosive railroad spikes at the get-go.

Selection of railroad spikes anchoring agent

There are two common types of anchoring agent: sulfur-anchoring amanuensis and h2o-soluble anchoring amanuensis.

Sulfur-anchoring agent

At present, anchor in railroad spikes is mainly apply sulfur-anchoring amanuensis in China. Sulfur-anchoring agent is easy to handle. But acidic electrolyte produces when HS, S2 and SO2 in sulfur-anchoring agent mixed with water. Acidic electrolyte tin cause rust in railroad spikes easily. In addition to, sulfur anchor demand use fire to make the sulfur. It results in some bad influence, including environmental pollution, waste of wood, impairment of crops, and and then on.

Water-soluble anchoring agent

With comparison and analysis, a new water-soluble anchoring agent is more suitable. It takes hydraulic cementing materials-pure portland cement 525 as cementing material. And also takes emery as aggregate. It is worth noting that adding a certain amount of antirust amanuensis to the water-soluble anchoring agent. Besides, ingredient is environmentally friendly material. In one case mixing various materials and water together, water-soluble anchoring amanuensis is ready to use. This kind of anchoring agent is useful to protect railroad spikes from corrosion.

Standardize anchoring engineering

Anchoring technology is one of ways to protect railroad spikes from corrosion. When you lot fasten railroad spike on railway sleepers, attention should exist paid to the following points:

• Using anchoring subclass according to requirement. Ensure accurate railroad spike position during anchoring.

• Cleaning the track holes, fill it up with anchoring agent the starting time time. Not too much, not too little, subsequently anchoring, the platform should exist 2mm higher than back up rail bed of sleeper (when rail prune is used together). The pinhole should exist filled with anchoring agent. Subsequently solidification, using grafter to clean upwardly spilled anchoring agent. Refacing the flat spaces around pinhole of railroad spike to avoid uneven surface. Flat surface can reduce water and protect railroad spikes from corrosion.

Coating anti-corrosive grease

Railroad spikes work under the condition of cold, heat, pelting, current of air and corrosive medium for a long fourth dimension. Railroad spikes are also afflicted by axial vibration and radial vibration. Normal anti-corrosive grease is far from enough to encounter the corrosion demand. So you need put solid filler, antioxidant, metal deactivator, anti-rust amanuensis into anti-corrosion grease. It can improve the anti-rust property and water resistance.

Anticorrosion of railroad spikes should focus on the railroad spikes selecting, installation and maintenance. More noesis about railroad spikes, click railroad spike for details.
