In the development of modern industry, how is the large-scale steel structure object such as the container car rusted and refurbished? Does the newly produced container carriage need to be derusted before painting?

Reason, here Dongguan Meijun Sandblasting Equipment Co., Ltd. tells you, but what kind of coating treatment needs to be derusted.

What are the advantages of sandblasting and rust removal before painting?

1.Sand blasting and rust removal can clean the rust and rust spots on the surface of the steel structure, and the cleanliness has reached SA2.5-3.0 industrial level.

2.Sand blasting and rust removal can form a concave-convex node on the surface of the steel structure and increase the adhesion between the steel structure and the coating.

3.Sandblasting can strengthen the surface of steel structures.

4. Sand blasting and rust removal makes the subsequent painting of the steel structure not easy to peel off and crack the paint.

5. Sandblasting and rust removal thoroughly cleans impurities, salt, rust, etc. on the surface of the steel structure to prevent oxidation and rust after painting.

Working principle of rust blasting machine for container carriage:

Using the compressed air of the screw air compressor as the driving force, the river sand (corundum, iron sand) is formed into a high-speed jet to the surface of the carriage through the pressure vessel.

With a certain cutting force, the old paint, rust spots, cement agglomeration and other impurities on the carriage will be cleaned up, so as to achieve the renovation effect! The refurbished sheet metal club

Showing a metallic color! Smooth surface after repainting!

Scope of application of rust blasting machine for carriage:

It is used in sandblasting and three-dimensional engraving of glass, marble and other stone materials, sandblasting in shipbuilding, surface treatment, rust removal and anti-corrosion treatment of steel structures such as bridges, railways, containers, and petrochemical facilities before painting.

Container carriage derusting sandblasting machine features:

1. There is no obvious dead angle in the refurbished carriage, and the cleaning speed for paint rust spots is fast!

2.The operation is simple; one person can operate it, including installation and debugging equipment, which is suitable for sandblasting and rust removal in various sites.

3.Energy saving and environmental protection, water and sand mixing is environmentally friendly and dust-free, and the price of water and sand is not high! Low cost to refurbish carriages!

4.Small footprint; mobile open type is easy to carry and fast to transport.

5.High efficiency and low cost; any outdoor installation can adapt to various river sand, quartz sand, copper ore sand, and steel sand.

6.High safety; the equipment is in the state of sand discharge and exhaust during sandblasting operation, and the mushroom top automatically relieves pressure after shutdown.

7.Sandblasting is a pure physical and chemical reaction; it is non-toxic, non-acid, non-corrosive, and does not affect the surface size of the workpiece.

8. Anti-corrosion and rust removal; it can complete the Sa2.5 rust removal standard for steel structures, including the renovation of old parts to support both wet and dry use.

9. Durable; the main wearing parts and spare parts are imported from Germany, except the wearing parts, which are guaranteed for one year and lifetime maintenance.

10. There is no size limit for processing; various non-standard steel structures, old equipment, and tool accessories have no dead corners on the surface of rust removal and cleaning

Prerequisites for this device:

1.Need to cooperate with 22kw35P or above screw air compressor and air storage tank for better effect.

2.It is necessary to wear sandblasting protective equipment (sandblasting cap, sandblasting suit, sandblasting gloves, sandblasting suit thermostat, anti-noise earplugs) for operation

Reminder: If there is a large amount of dust and environmental protection does not allow the construction, this equipment can choose ordinary river sand (yellow sand) with water mist sandblasting gun for environmental protection and dust-free one-time sandblasting.

 Features of rust blasting machine:

1：Six advantages; favorable price, complete accessories, excellent performance, cheap consumables, quality assurance and long service life.

2.：Easily remove rust; all kinds of steel structures, old equipment, rotted facilities, and spare parts refurbishment are as pervasive as sweeping thousands of troops.

3.：No sparks are generated; water mist sandblasting gun can be added to mix water and sand to remove rust to prevent sparks from being sprayed.

After-sales service details:

1. Free one-year warranty for machinery and equipment (except wearing parts), product life-long maintenance, and free technical guidance;

2. Provide professional consulting services for product updates and functional improvements;

3. Long-term inventory of surface treatment equipment and product parts to meet the needs of users to repair and replace parts;
