Electronic effect of graphene

The function and characteristics of scales graphite

Skin graphite, as a functional filler for coatings, is mainly used for anticorrosive coatings, fireproof coatings and conductive coatings. As an anticorrosive material, it is a rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent resistance. If you add chemical pigments such as zinc yellow to the formula, the rust -proof effect will be better.Scales graphite manufacturers believe that expansion graphite can be used as fireproof fillers. It is a graphite layer compound obtained by natural graphite thin slices as raw materials. Under heating conditions, the volume of expansion graphite quickly expands (300 times) to suffocate the flame, and at the same time, the expansion substance can be isolated, which can be isolate the flames, delay or interrupt the spread of flames, not burning, good flexibility, high surface energy, charcoal layer strength strength good. However, the volume and dosage of the expansion body should be appropriat

Graphite rotor action

The graphite rotor rotating nozzle is made of high-purity graphite. In addition to considering the need to disperse bubbles, the structure of the nozzle also utilizes the centrifugal force generated by stirring the aluminum alloy melt to evenly mix the melt into the nozzle with the horizontally sprayed gas, forming a gas/liquid flow to spray out, increasing the contact area and contact time between the bubbles and the aluminum alloy liquid, and improving the degassing and purification effect.Due to the characteristics of graphite such as self-lubrication, high temperature resistance, and corrosion resistance, graphite materials are made into graphite shaft sleeves, graphite sleeves, and other graphite processing parts with different specifications according to the use of different mechanical equipment. Our company has been engaged in the processing and manufacturing of graphite products in recent years. The most important characteristics of the processing of graphite shaft sleeves and

Introduction to the use of expansion graphite

The expansion graphite was discovered in the early 1960s. Many countries like to use it to study, so that many unexpected results can be achieved. The so -called expansion can be increased by more? That's right, more than double or even double! It is new carbon material! Many people don't know much about expansion graphite!Graphite crystals are two -way large -molecular layer -like structures. The C atom in each plane is combined with the C -C co -price bond, and the layer is combined with weaker Van Dehua.The layered structure of graphite is very typical. Each layer is a carbon atomic layer. The carbon atom in the layer is a strong covalent bond with SP2 hybrid orbit, that is, 1 2S electronics and 2 2P electronic hybridization, etc. The hybrid track of the price is located on the same plane and forms σ bonds each other, while the two unsteady 2P electrons are perpendicular to the plane to form a two -key π. This layered structure of graphite makes a certain gap between layers. Theref

How to distinguish the quality of high -purity graphite board?

In fact, many production manufacturers of high -purity graphite board are unclear how to differentiate the quality of high -purity graphite board. Some manufacturers say that they are used as fine particles, and some manufacturers say they are the secret recipes of their ancestors. In fact, the only key to judge the quality of high -purity graphite board is to query its density.In the electroplating and electrolytic industry, many manufacturers only favor the conductivity equivalent of high -purity graphite boards and ignore its density. Assuming that the density of high -purity graphite chips is small, it is very easy to form air holes on the surface layer. It is very easy to enter the lithium battery electrolyte of lithium battery, and then form a graphite pole. Period of use. It is convenient to use in the wear -resistant steel industry and can also be used to high -density fiber board industry.
