Donit sheet

Donit sheet

Donit sheets have a variety of colors, gray, white and black and have a density of 2 to 1.6 grams per cubic centimeter.

Donit sheet is made of asbestos sheet, which due to its special spatial limitation, graphite can be used instead of asbestos fibers.

Donit refractory sheet is composed of two asbestos sheets and steel sheet is used between them, the presence of this sheet between them increases the strength, heat and pressure tolerance.

All refractory sheets have the same benefits as the following:

High abrasion and tensile strength and high mechanical strength
Acceptable operation in different weather conditions and heat resistant
Stable against oxidation and chemical corrosion, maintaining optimal efficiency in alkaline and acidic environments
Ability to control pressures
The main material of dunite sheet is asbestos sheet, in which asbestos is used due to its compact fibers and sword shape, which has properties such as high temperature resistance, water penetration, oil and pressure.

This sheet is composed of two layers of asbestos sheet, in which punched steel sheet is used, which can be used instead of steel plate to match its price.

Donit sheet is mostly used in the production of washers.

Donit sheet is used as a washer for cylinder head insulation, exhaust sealing and parts insulation in fully automatic factories.

The thermal resistance conditions of Donit refractory sheet are as follows:

Maximum heat tolerance up to 1100 degrees Celsius
Indirectly for heavy use 900 ° C
Directly up to 700 degrees Celsius

The most prominent features of dunite sheet are as follows:

Has excellent strength and good density
Significant resistance to pressure
Do not lose quality and do not collapse the sheet in alkaline and acidic environments, resistant to chemical corrosion and oxidation
Very high mechanical strength
Donit refractory sheet is produced in three colors: gray, white and black, which has a thickness of 1 to 3 mm and is available in dimensions of 150 by 50 cm.

The most important applications of donit sheets are:

Manufacture of refractory and high temperature gaskets, cylinder heads, exhaust hoses and production of gaskets in engine rooms
Used as insulation of furnaces
Production of pressure washers in power plants, oil rigs and petrochemicals
