Wet desulfurization tower acid, alkali, high temperature and anti-corrosion coating

How can desulfurization towers resist strong corrosion? Unveil core anti-corrosion technology and safeguard smoke purification!

The desulfurization tower is the core equipment of the desulfurization system, which converts sulfur-containing flue gas into standard clean flue gas through complex processes. Its internal corrosion environment is harsh: the lower part is eroded by alkaline media, the middle part is corroded by strong acidic and alkaline substances, the upper part faces strong acidic gas corrosion, and the accessory components also need to withstand high-speed corrosive airflow friction.

In response to this challenge, ZS-1041 smoke anti-corrosion coating and ZS-1042Wet desulfurization tower acid, alkali, high temperature and anti-corrosion coatingBecoming the industry's preferred choice. Both have the following characteristics:

1. Environment: Temperature resistance up to 850 ℃, resistance to acid and alkali erosion, suitable for long-term working conditions of -45 ℃~600 ℃;

2. Strong protective performance: The coating is dense and wear-resistant, resistant to water vapor penetration, and effectively resists condensation sulfuric acid corrosion;

3. Long term durability: With a service life of over 10 years, stable thermal expansion coefficient, resistance to vibration cracking, and support for local repairs;

4. Environmentally friendly construction: The painting process is pollution-free and forms a lightweight and high-strength protective layer after hardening.

ZS-1042Wet desulfurization tower acid, alkali, high temperature and anti-corrosion coatingSpecially designed for high friction areas, with excellent bonding strength, it can be applied thick without cracking, solving the material fatigue problem caused by dust erosion in flue gas equipment. In addition, the inner wall of the desulfurization tower needs to be selected with targeted materials, requiring anti-corrosion coatings to have heat resistance, acid and alkali resistance, friction resistance, and toughness to adapt to thermal expansion and contraction during start-up and shutdown. During construction, it is necessary to strictly control the environmental conditions to ensure that the coating is firmly bonded to the substrate and achieve long-term protection.

Through scientific selection and standardized construction, the anti-corrosion system of the desulfurization tower can effectively block the penetration of corrosive media, ensuring long-term stable operation of the equipment.
