Strong acid and strong alkali environment: ETFE coating has good resistance to strong acid and strong alkali such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, etc., can maintain stability in these co
The agitator is sprayed with ETFE (ethylene tetrafluoroethylene copolymer) anti-corrosion coating, which has the following characteristics:
1. good corrosion resistance
Strong acid and strong alkali environment: ETFE coating has good resistance to strong acid and strong alkali such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, etc., can maintain stability in these corrosive media for a long time, is not easy to be eroded, and effectively protects the agitator substrate from corrosion.
Chemical stability: it has a high degree of chemical stability, and is not easy to react with other substances even in a complex chemical environment. It can resist the erosion of a variety of organic solvents, salt solutions, etc., and can be widely used in the prevention of agitators in chemical, electroplating, pharmaceutical and other industries.
2. good wear resistance
Anti particle wear: in the mixing process, ETFE coating can resist the erosion and wear of solid particles in the material, such as slurry mixing, architectural coating mixing and other scenes, which can effectively reduce the coating damage caused by particle friction and prolong the service life of the mixer.
High surface hardness: ETFE coating has high hardness, which can resist the scratch and collision of external objects to a certain extent, maintain the integrity of the coating, and maintain its anti-corrosion performance.
3. good cohesiveness
Prevention of material adhesion: the surface of ETFE coating is smooth, with low surface energy, and the material is not easy to adhere to the surface of the mixer, which not only helps to improve the mixing efficiency, but also reduces the material residue and avoids the corrosion and bacteria breeding caused by material accumulation, especially suitable for industries with high health requirements such as food and beverage.
Easy to clean: non sticky makes the cleaning of the mixer more convenient. It can easily remove the dirt and residual materials on the surface by washing with clean water or simple detergent, reducing the maintenance cost and cleaning difficulty of the equipment.
4. good high temperature resistance
Adaptability to high temperature environment: ETFE coating can maintain stable performance at high temperature and can withstand continuous use temperature of about 150 ℃. In some processes requiring high temperature stirring, such as high temperature reaction stirring in petrochemical industry and molten material stirring in glass fiber production, it can effectively protect the agitator and prevent coating failure and matrix corrosion caused by high temperature.
Thermal stability: it has good thermal stability. In the process of temperature change, the coating is not easy to crack and peel off, and can always maintain its anti-corrosion and protection performance.
5. good insulation performance
Electrical insulation: ETFE coating has excellent insulation performance, which can effectively isolate the electrical contact between the mixer and the surrounding environment, prevent the occurrence of electrochemical corrosion, and avoid safety accidents caused by equipment leakage. It has important application value in some occasions with high requirements for electrical safety, such as the electronic industry, power industry, etc.
Electrostatic protection: it can also play a certain role in electrostatic protection, reduce the accumulation of electrostatic generated by material friction in the mixing process, and reduce the risk of fire and explosion caused by electrostatic. It is suitable for the mixing of flammable and explosive materials.
6. environmental protection
Nontoxic and harmless: ETFE coating is nontoxic, meets relevant environmental protection standards and health requirements, and will not cause harm to the environment and human health. It can be used in food, medicine and other fields that directly contact human body.
Recyclability: ETFE material has certain recyclability. After the mixer is scrapped, the coating can be recycled through a specific process to reduce environmental pollution and meet the requirements of sustainable development.
