Some knowledge of the water treatment equipment anticorrosion technology

by:J&D WATER     2020-03-09
Water treatment equipment anticorrosion technology involved in water treatment equipment used in the industry is very important. Anti-corrosion technology also determines the efficiency of water treatment equipment and service life. In order to improve the efficiency of water treatment equipment and service life, need to master some knowledge of water treatment equipment of corrosion. Here introduce you some some knowledge of the water treatment equipment anticorrosion technology: 1, the correct selection of materials, and design: there are many different kinds of materials. Different types of materials in different environments have different corrosion rate. Choose good physical and mechanical properties, corrosion resistance is low, the price is relatively cheap material, meet the requirements of specific environment design. 2, adjust the environment: to improve the local environment. On the premise of conditions allow, recommended mild medium instead of strong corrosive medium. 3, inhibitors: inhibitors is divided into three categories: the gas phase, organic and inorganic. In general, add a small amount of corrosion inhibitor in corrosive environment can slow down the corrosion of metal. 4, cathodic protection: dc or sacrificial anode cathodic protection depends on external form the protected metal cathode, so as to reduce or eliminate the metal corrosion. 5, the anode protection: the need to protect the equipment as anode, introduce current to keep potential in central passivation zone. Corrosion rate can remain at a very low level. 6, alloying: adding alloying elements in the parent metal, accelerate the passivation, when joining to the corresponding proportion, can obtain excellent corrosion resistance of materials. 7, surface treatment, metal passivator in contact before using the environment or film-former, generate stable solid surface passivation membrane, greatly increase the resistance to corrosion. 8, metal coating and coating layer: use a thin layer on the steel bottom more resistant to corrosion of metal protection. 9, coating, organic coating the metal structure, protection atmosphere is more extensive corrosion protection methods. 10, lining: general for the entire lining material, suitable for contact with strong corrosive medium inside the equipment. All the above is to introduce the content, hope to be of help. If you want to learn more knowledge, you can visit our website, we will provide you with more professional information.
