Graphite sheet is composed of 99% pure graphite fibers, which due to the purity of graphite, this sheet has become brittle. Therefore, to improve this property, it can be combined with other refractory materials such as epoxy resin and fiberglass and carbon fibers.
This sheet has advantages such as very high performance in alkaline and acidic environments and stunning heat tolerance.
All refractory sheets have the same benefits; These benefits include:
Do not emit toxic fumes along with heat, non-combustible and tolerant of heat
Resistance to rust and erosion, acceptable chemical resistance and maintaining excellent efficiency in alkaline and acidic environments
Has high mechanical strength
Resistance to pressures
Has a long life
Prevent material leakage inside parts
Graphite sheet is made of pure graphite powder, glue and resin.
To increase the strength and heat resistance of graphite sheet, this sheet can be combined with steel or steel wire.
The most prominent features of graphite sheet are:
It has high cohesion due to the high density of fibers.
It has a low weight.
It has great flexibility (if combined with other refractory materials).
The highest temperature tolerance is up to 800 degrees Celsius, for high use it is 650 degrees Celsius and the lowest temperature is up to -240 degrees Celsius.
It can be used in various environments and is environmentally friendly.
Has an acceptable ability to prevent corrosion of parts and the ability to withstand the pressures applied.
It has high chemical resistance and performance in alkaline and acidic environments (except against concentrated nitric acid, or chromic acid).
It has high efficiency and good performance in various weather conditions.
It has a high electrical conductivity.
It has good mechanical strength.
The most prominent and prominent applications of this sheet include:
Insulation of parts in power plant industries
Sealing parts in the shipping industry
Insulation of equipment in the petrochemical industry
Production of washers for insulation
Sealing of boilers
Insulation of electrical boards
Sealing of fresh and salt water pipes
Construction of expansion joints
Sealing equipment in gas or steam environments
Graphite sheet has dimensions of 1 by 1.5 meters.
The thickness that makes this product very popular is 0.5 to 5 mm.
