Pure graphite sheet

Pure graphite sheet

The raw material in the production of pure graphite refractory sheets, as its name implies, is pure graphite, which is formed into a sheet by glue and resin and no other material is added to this sheet. Although this product has good thermal resistance and good pressure tolerance, it is still possible to improve pure graphite sheet with metal wire to improve its properties. Other advantages of this refractory material include self-lubrication, resistance to corrosion caused by chemicals and long life.

Sanat Pars Refractory Store is ready to provide consulting, sales and sending of pure graphite refractory sheets, in various dimensions and thicknesses throughout the country.

Refractory sheets are one of the most cost-effective refractory materials available, often used in the form of washers to seal and fill gaps between parts. This, in addition to neutralizing the pressure on the parts and thus increasing their durability, prevents liquids from leaking out of the parts. This has made refractory sheets popular insulators in various fields of industry.

If the refractory sheet selected for insulation does not have the appropriate flexibility and strength to withstand the temperature and pressure on the parts, despite the high cost, irreparable damage may be done to the equipment or the liquid inside them may leak out. Leak. Therefore, before choosing the right refractory sheet, the needs and environmental conditions should be well considered. Today, due to the different refractories available, buyers can have a wide range of products and choose the right option according to their field of work and needs. In this article, we intend to study pure graphite refractory sheet, which is widely used in various fields of industry and has gained great popularity among refractory sheets.

Although graphite is an expensive refractory material, it has a special place among various industries due to its remarkable chemical properties, favorable pressure resistance, and high heat tolerance. On the other hand, the use of graphite in the production of refractory sheets gives it stunning flexibility.

The raw material used in the production of pure graphite sheet is graphite powder with a purity of more than 90%, which has several properties such as high heat tolerance, pressure resistance, high durability, self-lubrication, anti-corrosion and good electrical conductivity. Special resin and glue are used to convert graphite into sheets. In some cases, in order to increase the positive properties of this refractory sheet, such as heat tolerance and pressure resistance, it is reinforced with chrome and nickel wires.

At first glance, using this product may not seem cost-effective; Because the purchase price and cost of replacing asbestos refractory sheets with graphite washers is higher. But the first advantage of using this refractory material is the safety and health of people in contact with it, which is very important. Also, the stunning resistance of graphite to corrosion due to exposure to chemicals, in addition to increasing the life of parts, reduces maintenance costs. The only problem with pure graphite sheet is that it is brittle and brittle, which can be solved by adding glass fibers and resin.

Pure graphite sheet is produced in dimensions of one to one and a half meters and thickness up to about 5 mm.

Pads made of pure graphite, in addition to the desired thermal resistance and maintaining dimensional stability at sub-zero temperatures, have a good resistance to pressure due to the high density of the fibers. In addition, due to its stunning resistance to corrosion due to exposure to chemicals, this product is mostly used for high temperature insulation in the petrochemical industry. Pure graphite refractory sheets are also used to seal pipes, exhausts and pressure vessels.

It is suggested that you read the article on pure graphite refractory sheet on the website of Pars Sanat Pars to get more acquainted with pure graphite sheet.

Among the many outstanding features of pure graphite refractory sheet, the following can be mentioned:

High temperature tolerance up to 820 ° C; However, experts in this field have estimated its application temperature at 650 degrees Celsius.
Maintain dimensional stability at low temperatures, up to minus 240 degrees Celsius.
Impressive flexibility, due to having more than 90% carbon
light weight
Positive performance in humid environments
Resistance to high pressure and its neutralization
Can be used in situations where the quality of the seal is of particular importance
Resistance to most minerals and organic acids
Significant impermeability to most liquids and gases
high durability
Extraordinary chemical properties and resistance to elastomeric base materials; However, the use of pure graphite sheets is not recommended for exposure to strong oxidizing compounds such as chromic acid or concentrated nitric acid.
It has a pH range of zero to 14, which makes this product suitable for use in most chemical environments.
Significant resistance to corrosion of saline solutions and most acidic and alkaline substances
Optimal electrical conductivity

The existence of such stunning advantages in pure graphite refractory sheet has led various industries to use it to insulate their parts. The most prominent uses of this refractory product are:

Production of gaskets for thermal and electrical insulation
As an alternative to asbestos gaskets
Insulation of special joints in difficult conditions
Insulation of parts used in salt and fresh water piping
Paper pulp manufacturing industries
Insulation of boilers
Mining Industries
Petro industry

chemistry
