Klingrit sheet

Product description

Klingrit sheet

Klingerite refractory sheets are made using asbestos powder, but are coated with a layer of rubber resin to improve flexibility and reduce the damage caused by asbestos dust.

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

Today, refractory sheets, which are mostly used as washers, are among the most economical and popular refractory materials on the market that are used for insulation in various fields of industry. These sheets, by bearing and neutralizing the pressure on the parts, in addition to protecting them, significantly increase the life of the equipment. Also, the use of fireproof sheet at the joints prevents the leakage of liquids. Sometimes some of their positive properties can be enhanced by wiring the sheets or combining them with other refractory materials.

An important point that has always been of great importance in the field of equipment insulation is the existence of a relationship between strength, thermal resistance and pressure tolerance of refractory material, with the needs and context of consumer activity. If this issue is ignored, despite the high cost, the desired result may not be achieved or irreparable damage to the parts. Currently, the variety of refractory sheets allows industries to choose the right sheet from a wide range of options. In this article, we intend to examine Klingerite sheet, as one of the most popular refractory materials, which according to its properties, is used in certain areas of the industry.

As mentioned, Klingerite refractory sheets are produced by combining asbestos powder and different rubber resins. These sheets are made in the form of cordless, wired, graphite impregnated wire, and graphite impregnated wire. Before going into the details of the production of this product, it is better to take a look at the properties of asbestos refractory material to have a clearer understanding of the continuation of the discussion.

Asbestos washers were introduced to the world by an Austrian scientist in the late 19th century by compressing flexible asbestos fibers, and within a short time, they became so popular that they were used in most areas of insulation. The resistance of asbestos fibers to heat, pressure and chemicals has led to the insulation of most industrial equipment by this refractory material, in the form of various products such as packing, yarn, fabric and refractory sheets. These stunning properties of asbestos fibers are due to the high density of their sword-shaped fibers, which in addition to thermal resistance and impermeability of these fibers, result in significant energy savings.

Exactly one hundred years later, in the late twentieth century, experts saw a dramatic increase in reports of serious lung disease in people who came in contact with asbestos. Further research revealed the harmful effects of asbestos refractory dust on the environment and human health, leading to a widespread ban on the use of this refractory in industry. Although scientists have made many attempts to replace asbestos with other environmental refractories, it has been impossible for many industries to ignore the unique properties of asbestos. For this reason, the use of asbestos was limited to places that did not come into contact with humans.

Klingerite sheet is named after Klinger Company, which is one of the most prominent manufacturers of this refractory sheet. To make this refractory sheet, first some silicone oil is added to the asbestos powder to reduce the friction in this product by providing a smoother surface in addition to controlling its toxic dust. This results in a brittle, white paste that is not very usable. To solve this problem, rubber resin is added to the paste obtained from asbestos powder and silicone oil. This not only eliminates the problem of dough brittleness, but also improves pressure tolerance and heat resistance. Then, to ensure the complete composition of the ingredients, the resulting dough is baked in an oven at 500 ° C and then cooled to 100 ° C. Finally, it is pressed by the machine to produce a square sheet with a thickness of 0.5 to 6 mm and a side of 150 cm.

Among the most well-known factories producing this refractory sheet, we can mention Klinger, Brugman, Extra and Frenzlit.

As mentioned, sometimes the performance of sheets can be enhanced by adding wire or combining refractories. In Klingrit refractory sheet, wiring will increase its pressure resistance and strength. Also, in some cases, covering the surface of the Klingrit refractory sheet improves its heat tolerance.

Klingerite refractory sheet, with raw materials such as asbestos powder, silicone oil and rubber resins, has outstanding properties, some of which will be mentioned below:

High thermal resistance up to about 550 ° C; This amount will increase with the reinforcement of the fibers of this sheet by graphite.
Direct fire and heat resistance
Optimal pressure tolerance; The resistance of klingerite sheet to pressure is significantly increased by wiring it.
Maintain structure and dimensional stability at temperatures as low as minus 100 ° C
High fiber density that leads to product strength
Excellent chemical properties and maintain yields in the case of moa

Jah with semi-acidic environments, oil, alcohol, oil, etc.
UV resistance
The mentioned properties for Klingrit refractory sheet have caused various industries to benefit from it, such as power plants, petrochemical industries and oil industry.
