What is the coating added to the anticorrosive surface? This substance can be simply called an anticorrosive coating. This is a coating that is widely used in transportation, marine, construction, energy engineering and other fields. It plays an important role in anti-corrosion of objects. According to the different properties of the anticorrosive coating film, it can be divided into conventional anticorrosive coating and heavy anticorrosive coating according to the corrosion resistance and the use requirements of the anticorrosive coating.

Anticorrosive coatings are classified according to their ingredients, such as inorganic anticorrosive paints, acrylic anticorrosive paints and polyurethane anticorrosive paints. According to the application classification, it can be divided into anticorrosive paint for ships, anticorrosive paint for furniture, anticorrosive paint for automobiles and so on. According to the solvent, it can be divided into oil-based anticorrosive paint and water-based anticorrosive paint. No matter what kind of anticorrosive coatings belong to, the anticorrosive coatings are a mixture of multiple silicate minerals. In order to achieve the anticorrosive effect, no matter what type of anticorrosive coating, the anticorrosive paint thickness checker needs to reach the standard thickness before it can be used.

The anti-corrosion coating on the anti-corrosion sirface has a great effect. The anti-corrosion coating not only prevents corrosion, but also can isolate the corrosive medium from the outside and prolong the service life of the material. In addition, anticorrosive coatings can also play a role in shielding. The anticorrosive coating is applied to form a paint film on the metal surface. After the anticorrosive coating is formed, the anticorrosive coating isolates the surface of the object from the external environment and prevents water, oxygen, ions, etc. from reaching the surface. This shielding and isolation effect of anticorrosive coating is very important for concrete, wood, masonry in the engineering and construction fields. Such an anticorrosive coating is equivalent to directly providing efficient mechanical isolation of materials. Compared with the traditional method, it also saves time and effort.

The anticorrosive coating on the anticorrosive coating can also interact with the metal surface to passivate the metal surface or generate protective substances. This can improve the protective effect of the anticorrosive coating and delay the corrosion effect. In order to better carry out anticorrosion, some active antirust coatings can also be used at the bottom of the anticorrosive coating, these components have a certain passivation effect on the metal. Take chromate as an example, when a small amount of water penetrates the paint film, a small amount of dissolved pigment will passivate the substrate. Therefore, the corrosion inhibition effect can make up for the insufficient shielding effect of the anticorrosive coating, which in turn can prevent the loss of corrosion inhibition ions, making the corrosion inhibition effect more stable and more durable.

The anticorrosive coating material is beautiful and bright. It can also play a decorative role when applied properly, making the visual effect better. In addition, the anti-corrosion coating on some anti-corrosion coatings also has its own special functions brought about by some special properties, such as discoloration and static conduction. These mainly depend on the different nature of the different ingredients of the anticorrosive coating.

Anticorrosive coatings have many functions, but to achieve these excellent effects, the thickness of the anticorrosive coating must meet the requirements. Therefore, in the loading process of the anticorrosive coating, pay attention to the thickness change of the anticorrosive coating at any time to ensure that the minimum requirements are met. After the construction is completed, the thickness inspection with an anti-corrosion paint thickness checker should be performed in time. In the subsequent spot checks, the measurement results of the anti-corrosion paint thickness checker should also be paid attention to to ensure the thickness of the anti-corrosion coating.
