Conductive paint types and functions Explain the working principle of conductive paint

There are many types of products on the market that are well known to everyone, and the function of each kind of paint is not the same, there are improved water resistance of the base layer, enhanced corrosion resistance, fire retardant and so on. The role of conductive paint can indeed shield electromagnetic interference, it is a paint with conductive properties, it is mainly used in the metal surface. Then we have to know about the role of conductive paint types and forth, as well as conductive paint works related content.

The type and function of conductive paint

First, the kind of introduction

Nowadays, there are many kinds of conductive paints on the market. Usually, they are classified according to intrinsic conductivity and doped conductive paints. Then look at the former's film-forming substances which mainly contain intrinsically conductive polymers. The composition of the latter film-forming substance is very complicated, and it can be further subdivided into carbon-based conductive coatings, conductive graphite coatings, conductive coatings of metals, conductive coatings of nanotubes, and conductive coatings of metal oxides.

Second, the role of elaboration

The conductive paint should not be unfamiliar to everyone, and its main construction method is to use spray coating. Its function is to make non-conductive and weak conductive materials have strong electrical conductivity. There are often many materials in life that are very suitable, but many are abandoned because they cannot be conductive, and conductive paints bring us a lot of convenience, taking into account the adsorption capacity of conductive paint. Therefore, conductive paints are generally coated on the surface of non-metallic materials such as PC, ABS, etc., if other places do need to apply conductive paint. Construction workers generally apply a primer to the underside of the conductive paint to ensure that the conductive paint has an adsorption capacity that does not affect its effectiveness.

How conductive paint works

First, the principle of specific work of conductive paint We come to understand, in fact, it is through the use of spraying and brushing, and then let those insulated non-metallic or non-conductive surface, with the same metal as the absorption, conduction and attenuation of electromagnetic waves feature. In order to play the role of shielding electromagnetic interference, the emergence of conductive paint, effectively solve the problem of non-metallic surface to achieve electrical connection.

Second, it is an anti-electromagnetic interference paint made of electroplated silver particles, and it has many advantages, such as labor saving, time saving, convenient, good adhesion, smooth, strong cohesion, no loose particles. Can be used for metal, composite materials as the substrate of mobile phones, calculators, precision instruments and other shell wall coating material, drying and curing after the paint layer performance is stable. The delicate smoothness of the workpiece surface and the conductive properties of pure silver conductive paint, fine conductive particles ensure the safety of electronic components.

Third, there is one point that needs to be highlighted to remind that we must be able to ensure that the coating and the base surface of the two aspects of the ability to attach. Therefore, under normal circumstances, we can only use conductive paint on the surface of non-metallic materials such as PC and ABS. If you use it on an abnormal surface, you may need to use primers and primers.

More about the role of conductive paint types and forth, as well as the content of the conductive paint works on the introduction here, I hope these help you.
