As an important part of road traffic safety facilities, the quality and performance of corrugated guardrails are directly related to the safety and smoothness of road traffic. The anti-corrosion and anti-rust treatment of the corrugated guardrail is the key to ensure its long-term function.
At present, the commonly used anti-corrosion and anti-rust treatment of corrugated guardrails mainly includes hot-dip galvanizing and hot-dip galvanizing spraying. Today, let's talk in detail about the standards and characteristics of hot-dip galvanizing spraying.
Hot-dip galvanized spraying treatment is a more common way of anti-corrosion and anti-rust of guardrails. The treatment starts with the raw material of the guardrail for profiling, then hot-dip galvanizing, and finally spraying. The standard for spraying plastic treatment of the national standard corrugated guardrail is the thickness of the galvanized layer is 270g/㎡, about 40um, the thickness of the spraying is 76um, and the total thickness of the anti-corrosion layer is not less than 116um.
Due to the thick anti-corrosion layer, long anti-oxidation time, and good anti-corrosion and anti-rust effect, the hot-dip galvanized sprayed guardrail board has the characteristics of anti-corrosion and anti-scratch, long service life and low maintenance cost.
Compared with hot-dip galvanized spraying, non-standard galvanized whiteboard spraying is a relatively simple way to prevent corrosion and rust. This treatment uses galvanized sheet to be directly profiled and then sprayed. The thickness of the zinc layer of galvanized sheet is usually within 100g, and the thickness of spraying is 40um.
Although the cost of galvanized whiteboard spraying treatment is relatively low, due to its thinner zinc layer, the anti-corrosion and anti-rust effect is relatively poor, the protection period is also short, and the anti-scratch effect is also poor. Therefore, galvanized whiteboard spraying is not an ideal choice for corrugated guardrails that need to be used for a long time and withstand harsh environmental conditions.
In addition to the anti-corrosion and anti-rust treatment, the quality of the corrugated guardrail is also related to its raw materials, production process and other factors. High-quality guardrail board raw materials should have good toughness and impact resistance to ensure that they can effectively absorb impact energy and reduce injuries to vehicles and passengers in the event of traffic accidents.
At the same time, the production process is also an important factor affecting the quality of the corrugated guardrail. Reasonable production process can ensure the dimensional accuracy, shape stability and spraying quality of the corrugated guardrail, so as to improve its performance and service life.
In the production and use process of corrugated guardrails, some details need to be paid attention to. For example, when installing corrugated guardrails, they should be installed according to the design requirements to ensure the stability and protection effect of corrugated guardrails.
In addition, the maintenance and maintenance of the corrugated guardrail is also very important. Regularly inspect and clean the dirt and debris on the surface of the corrugated guardrail to maintain its good performance and appearance. For corrugated guardrails that are damaged or aging, they should be replaced or repaired in time to ensure their safety and effectiveness.
In short, the anti-corrosion and anti-rust treatment of the corrugated guardrail is the key to ensure its long-term use. Hot-dip galvanizing spraying treatment has the advantages of anti-corrosion and anti-scratch, long service life and low maintenance cost, and is a more effective way to prevent corrosion and rust. Although the cost of galvanized white board spraying treatment is low, the anti-corrosion and anti-rust effect is relatively poor, and it is suitable for some temporary or short-term use occasions.
When choosing a corrugated guardrail, we should comprehensively consider its raw materials, production technology, anti-corrosion and anti-rust treatment methods and other factors, and choose high-quality products and services to ensure the safety and smooth flow of road traffic.
