The current：INDUSTRIAL CORROSION and floor > Industrial corrosion |
|
Strengths of the systems：
* Overall corrosion protection systems
* From Germany, focus on surface protection, Asplit systems
* High temperature&pressure resistance, heavy corrosion protection, suitable for complicated conditions
* Mortars for tiling, laminates for sealing |
Examples：
1. Brick lining of autoclaves in metallurgy industry, selecting mortar
Medium：Slurry with 4% sulfuric acid
Operation temperature：210-220°C
Operation pressure：1.8-2.2 MPa。
Anti-corrosion design：Sealing layer + brick-lining with Asplit VP 788 mortar and Asplit FQ mortar
2. Floor protection for stripper hangar, selecting laminate
Medium：Stripper, methylene chloride mixed with phenol and formic acid or methylene chloride mixed with toluene, ethanol and sodium chromate.
Operation temperature：Ambient
Mechanical stress：heavy load and wear-resistance, afford the air plane and related equipment.
Other requirements：Static conductive, combustion proof.
Anti-corrosion design: Asplit LC Laminate
3. Lining of the trencher for vinyl chloride workshop, selecting laminate and mortar
Medium: Dichloroethane, hydro-chloride and water
Design temperature：-13—180°C
Design pressure：1.41MPa。
Anti-corrosion design：Asplit LF laminate+acid-proof bricks with Asplit VP 788 mortar
4. Corrosion check list and the anti-corrosion design
Normally the chemical, temperature and mechanical stresses the objects face must be checked carefully before the anti-corrosion design forms. |
