Corrosion-resistant paint for steel structures.

Common primers include: red anti-rust primer, epoxy zinc-rich paint, and iron red epoxy primer, etc. The primer should have good adhesion and anti-corrosion properties.

Common surface paints include gray lead paint, alkyd enamel, and phenolic enamel, etc. Surface paints are used to prevent the aging of primer and provide a good appearance in color. Therefore, surface paints require good weather resistance, moisture resistance, and heat resistance, along with good chemical stability, low light sensitivity, and resistance to chalking and cracking.

General anti-corrosion measures for reinforced concrete include ensuring the density of the concrete, maintaining the thickness of the reinforcing steel protective layer, and limiting the dosage of chloride salt additives or using anti-corrosion agents. Due to the vulnerability to corrosion, the use of chloride salt additives should be prohibited for reinforcing steel in prestressed concrete.

Recycled iron metal raw materials come from all directions, often a mixture of ferrous metals, non-ferrous metals and their alloys, and are interspersed with plastics, rubber, paint, grease, wood, mud and sand, fabrics, etc. The following processes must be carried out before smelting:

1. Category: Due to the chaotic source of raw materials and the diverse nature of materials, it is necessary to manually sort and organize them for ease of later operations.

2. Disassembly: Many materials must be disassembled to separate the recycled iron components, which also facilitates manual screening of other impurities.

3. Screening: Remove other impurities or magnetically separate iron components.

4. Compaction: Utilizing the HDYJ metal compactor (including metal chip compactor and metal baling machine), we process pig iron materials into compact blocks for easier storage and transportation, as well as to reduce losses during transportation and smelting in the recycling and reuse process.

Additionally, various production processes such as crushing, drying, pre-combustion, and degreasing and grinding are required based on different production needs.Severely mixed scrap alloys are used as raw materials for remelting and metal extraction.
