Conductive paint is a kind of conductive material that many people are not familiar with in life. However, it can be seen in industry, architecture and some occasions. For most people, they still ask what the conductive paint is. Next, I will give you a detailed introduction.

I. performance advantages: Shielding coating: stable conductivity, wide coverage, can meet the requirements of customers, can pass the test of testing institutions, many high-end products are shielded by shielding coating. Vacuum plating: poor conductivity, poor coverage, such as corner, column and other places can not be electroplated, so it can not achieve a very ideal shielding effect. 2. Technical advantages: Shielding coating: the shielding technology is relatively mature with a history of more than 60 years. It was first introduced from western countries and recognized by western countries. It is widely used in the electronic industry. It has passed ROHS certification, providing guarantee for the export of high-end products.

Conductive paint is a kind of paint with good conductive performance, which uses composite particles such as copper and silver as conductive particles. It is a single component, labor-saving, time-saving, convenient, adhesion good, flat, cohesion strong, no loose particles. It can be used for the mobile phone, calculator, precision instrument and other shell internal wall spraying materials with metal and composite materials as the base material.

The water-based electromagnetic shielding coating is an inevitable trend in the development of conductive coatings, because solvent based coatings will volatilize a large number of harmful substances (such as VOC) in the process of use, which will have a harmful impact on the environment and people's physical and mental health. Researchers in some developed countries have found that building coatings, as decorative and protective materials for buildings, contain aromatic, halide, formaldehyde and various toxic volatile organic compounds VOC, which have a great impact on human health. Long term absorption of VOC will lead to fatigue, loss of memory and coordination functions and nervous system diseases.

Instructions 1. Characteristics of base material: the base material must be clean, dry and free of oil stain and release agent. Use alcohol or special solvent to scrub or soak the surface of equipment. 2. Mixing and dilution: before use, it must be stirred evenly to ensure that there is no precipitation. Normal use does not need to be diluted. If it needs to be diluted, it can be diluted to the viscosity required by the construction with boiled oil. The recommended dilution ratio is 2 parts of oil and 1 part of diluent (i.e. 2:1).

NX-201 is a special conductive paint for electroplating produced by our company. Can brush, spray, roll coating on shell, gypsum, wax crafts, silica gel, plastic, other composite materials as the substrate surface plating. It can be dried or dried naturally. After drying and curing, the performance of the paint layer is stable, the surface is fine and smooth, the hardness is high and it is not easy to touch flowers, and the edge of the paint film is neat and free of burrs. After plating, the surface coating is even and beautiful. Reduce all kinds of complex electroplating pretreatment. High production efficiency and cost saving. Coating characteristics Color: Gold Specific gravity: 1.3 ± 0.05 (ASTM d1475-98) Viscosity: thixotropic mixture Solid content: 45 ± 1% Theoretical coverage: 12m2 / kg (film thickness = 13 μ M

Conductive paint is to add conductive powder such as silver, copper, nickel or graphite into the varnish, so that the obtained paint layer has conductivity. Commonly used varnish is polyurethane or acrylic varnish. In addition, anti precipitation agent and dispersant are often added to reduce the sedimentation rate of conductive powder and make it well dispersed. In order to prevent the oxidation of conductive powder, antioxidants are often added. The commonly used conductive powder is nickel powder. The coating process is as follows

matters needing attention: Before use, the paint shall be completely stirred in the paint tank evenly before use. After stirring, the silver copper metal particles are evenly dispersed, and the coating film can achieve the conductivity. After the paint is diluted, it is better to mix it frequently for no less than 5min once to achieve the best conductive effect after coating; the diluted product should be used up as soon as possible to avoid long-term storage, because it is easy to precipitate after dilution, but it will not affect the use characteristics after mixing. Protective measures: during use, ensure that the working environment is well ventilated, avoid long-term direct contact or inhalation, and do not pour the paint into the ditch or sewer to pollute the environment.

The world of plants and home electronics usually does not overlap. But a new device that combines electronics and biology is a major step toward a world where plants and computers are increasingly intertwined.

On July 8, Dongxu photoelectric, a liquid crystal glass substrate enterprise, released its graphene based lithium-ion battery product in Beijing, which is known as the world's first graphene based lithium-ion battery. Various media reported and praised it for accelerating the pace of graphene industrialization. However, my opinion on this product is that it has no impact and basically uses the technology of tool.

Graphene bubbles blow too much. I'm a battery guy. Try to answer the landlord's question. First of all, I can't make a conclusion that graphene is used in other directions. In the field of battery, especially in the direction of lithium battery, being a "graphene battery" basically belongs to bullshit (in this case, it doesn't include new batteries such as super capacitors and lithium sulfur, which may be more optimistic).

Conductive plastics or polymers are relatively new materials. Its predecessor is common in televisions and mobile phones based on organic light-emitting diodes (OLEDs). Different from metal based devices and circuits, the polymer is flexible, easy to mass production and biocompatible. The conductive plastic is made from the earth's rich elements (carbon, nitrogen and oxygen) and can also be made by "ink printing". Collins's material has two other important properties: it can transmit electronic and ionic signals, which are the main mode of transmission of neurons in the brain. These characteristics are also crucial for the materials in the battery.
