Shandong cast iron guardrail manufacturers have taken into account the characteristics of the outdoor environment in the production process, in the selection of materials and coatings are striving to achieve rust-proof, wear-resistant, corrosion-resistant, anti-exposure and so on, but Xiaobian should remind you that in order to prolong the life of outdoor iron facilities, the following should be done:
1. Remove rust
If the iron fence is rusty, don't claim to grind it with sandpaper。 If the rust is small and shallow, you can apply cotton yarn dipping machine oil on the rust。 After a while, you can wipe with cloth to eliminate the rust。 If the rust has been enlarged and become heavier, the relevant technical personnel should be invited to repair。
2. Avoid bumping.
This is a point that should be paid special attention to in the process of handling iron products, iron products should be handled carefully and lightly; the place where iron products are placed should be the place where hard objects are not often encountered; the ground where iron products are placed should also be kept flat, and the iron fence should be ensured to be firm in installation. If it is unstable, the iron fence will change over time. Shape, affect the service life of iron fence.
3. Attention should be paid to moistureproof.
If only the general outdoor air humidity, you can rest assured of the rust-proof iron fence。 In case of foggy weather, dry cotton cloth should be used to wipe the water droplets in iron art; in case of rainy weather, the water droplets should be wiped out in time after the rain stops。 Because acid rain is rampant in most parts of China, the rainwater left on iron art should be wiped out immediately after rain。
4. Dust removal should be carried out regularly.
Outdoor dust flying, cumulative, iron facilities will fall on a layer of floating dust. It will affect the colour and lustre of iron art, and then lead to the damage of iron art protective film. Therefore, outdoor iron facilities should be wiped regularly, usually with soft cotton fabric.
5。 Keep away from acids and bases
Acid and alkali are the "number one killer" of iron fence. If acid (such as sulphuric acid, vinegar) and alkali (such as methylalkali, soapy water and soda water) are improperly stained on iron fence, the stain should be washed out with clean water immediately and then dried with dry cotton cloth.
