Overview of Donit Refractory Sheet:
Donit refractory sheet is one of the newest products in the market of refractory materials industry. There is no specific name for Donit refractory sheet yet, and many experts and technicians in petrochemicals and power plants know this refractory sheet as the embossed asbestos. Regarding the structure of this refractory sheet, we must say that the Donit sheet is composed of two asbestos sheets with layers of metal and stainless steel or 316 sheet. When all these components are pressed together and connected; They form a cohesive structure and a shape that has very good mechanical properties. Donit refractory sheet is the most suitable option among pressure refractory sheets. Temperature tolerance of this sheet in ambient conditions up to 1100 ° C and in working environment and continuous conditions up to 900 ° C and against direct flame up to 700 ° C temperature tolerance is predicted for this product. The presence of steel in this refractory sheet has caused us to tolerate more pressure, heat, tension and abrasion, and at very high temperatures, a good strength of this sheet can be observed. The dimensions of this product are 150 by 50 cm and the thickness is 1 to 3 mm. Due to the many features of Dunit sheet, there are many applications for this product, some of the most important of which are discussed:
The most suitable option for use as insulation and production of pressure washers in power plants and petrochemicals as well as oil rigs
The most suitable choice for the production of fireproof gaskets for engine, cylinder head, exhaust side and high temperature gaskets
Suitable for use as furnace insulation
Production of engine room washers
