Tanjid graphite sheet
The structure of Tanjid graphite sheet is such that a layer of 304 or 316 steel, which forms a kind of inner layer of the work, is punched or smooth, with a special adhesive and resin placed between two layers of pure graphite sheet. And are pressed to each other.
First, we will deal with the structure of the materials used in the graphite sheet.
Steel 304:
Steel 304 is the most common type of stainless steel. This steel contains chromium and nickel as the main non-ferrous elements. Its chromium is between 18 to 20 percent and the amount of nickel is between 8 to 10.5 percent. This steel belongs to the austenitic stainless steel family and has less electrical and thermal conductivity than carbon steels. Application 304 steel has no magnetic properties. The corrosion resistance of this alloy is higher than conventional steels. 304 stainless steel can be easily formed into various shapes, so it is widely used.
Steel 316:
316 stainless steel alloy contains molybdenum in its structure. This element increases the general corrosion resistance, improves the corrosion resistance of the cavity against chlorine ion solutions, and increases the strength at high temperatures. The properties of this alloy are similar to stainless steel 304, except that stainless steel 316 is stronger at high temperatures. Corrosion resistance is very high, especially against sulfuric acid, hydrochloric acid, acetic acid, formic acid, tantaric acid, sulfate chlorides, and alkaline. L316 stainless steel grade is a modified alloy with a lower percentage of carbon to minimize the deposition of harmful carbides in welding.
Resin adhesive:
Resins are a kind of organic and highly sticky compound that can be both synthetic and natural. This material hardens under certain conditions. The difference between natural and synthetic resin is in its chemical properties and how it is made.
Graphite: Graphite is a very soft, black mineral composed of carbon atoms.
Graphite, whose chemical symbol is C, is formed by the metamorphism of carbonaceous sediments as well as by the reaction of carbon compounds with hydrothermal solutions. Graphite is formed when carbon is exposed to heat and pressure from the crust and the upper part of the mantle. In order for graphite to form, it must be pressed to 75,000 pounds per square inch at a temperature of about 750 degrees Celsius.
Familiar with the basic structure of the graffiti graphite sheet, we now examine the product that is created from this combination and its features.
Embossed graphite sheet:
As you know, pure graphite sheet is very fragile and the presence of this layer of steel causes its resistance to heat, pressure, tension and rupture to be significantly increased. The heat tolerance of graphite sheet is up to positive 550 ° C and easily maintains its stability at minus 200 ° C.
The amount of pressure that this product can withstand is up to 200 times. Due to these features, Tanjid graphite sheet is widely used to make cylinder head gaskets and seals in all types of engines. Tanjid graphite sheet is available in thicknesses of 1 to 5 mm and in dimensions of 100 by 150 cm and 150 by 200 cm.
