Product description

Bone fiber

Bone fiber is a thermoset composite made from layers of cellulose paper under high pressure and heat, and phenolic resin and is suitable for use at high temperatures up to 120 ° C. Also, refractory bone fiber has a good resistance to electricity and wind. Of course, it should not be forgotten that the final quality of this refractory material is directly related to the quality of cellulose paper and phenolic resin used in it. To make bone fiber, the paper is impregnated with phenolic resin at high temperatures and pressures.

Sanat Pars Refractory Store is ready to provide consulting, sales and sending of bone fiber in various dimensions and thicknesses, all over the country.

Generally, refractory materials, due to having many positive properties, including high temperature tolerance up to about 538 ° C, high pressure resistance and neutralization, mechanical properties and thus wear and tear tolerance, as well as chemical resistance and positive performance in Exposure to most acidic and alkaline materials, used by various industries to insulate parts and improve equipment efficiency. In general, refractories, by significantly reducing energy loss and preventing erosion in parts, increase their lifespan and durability.

In this article, we intend to investigate bone refractory fiber, which is produced by covering phenolic resin by covering compact layers of cellulose paper and is used in several fields. But first we will take a brief look at the properties of cellulose paper and phenolic resin to make it easier for us to understand the benefits of this versatile refractory.

Most plants can provide the raw material for making cellulose paper. Because to produce this type of paper, we need cellulose that can be converted into fibers; And cellulose is a substance that is present in the structure of almost all plants.

The question may first be asked how cellulose molecules will find the adhesion needed to make paper. The fact is that cellulose molecules are made up of glucose filaments, and because of this, moisture causes these filaments to stick together. As cellulose gets wet, the cellulose molecules dissolve in the water, and in later stages, when the pulp begins to dry, the re-bonding of the cellulose and glucose molecules holds the paper in place.

To make cellulose paper, the cellulose in the plant is first removed, boiled and beaten. It is then crushed and the resulting small fibers are pressed and dried to form a paper. If more strength is required in cellulose paper, the fibers should be longer, which means that it is necessary to remove the cellulose paper from the shredding process and the fibers should be crushed alone. In this way, the fibers remain healthy while being separated.

As mentioned earlier, to prepare refractory bone fiber, compacted layers of cellulose paper are impregnated with phenolic resin under high temperature and pressure.

Phenolic resin production has two stages. First, the fibers of paper, cotton or glass are exposed to heat and high pressure, and at the same time, synthetic resin is added to it. Phenolic is very light and has considerable strength and hardness.

The stunning properties of this versatile material, including its extraordinary physical properties, resistance to chemical agents, high heat tolerance and dimensional stability, have led to its widespread use in various fields. For example, phenolic weights are lighter than aluminum and have the lowest possible water absorption. In general, the performance and efficiency of this material in hot and humid environments has been evaluated positively. Phenolics are also highly resistant to impact and abrasion and can be easily molded. The chemical resistance of this material also prevents corrosion and erosion.

By adding resins to phenolics, we also make them flame resistant. Phenolic resins are used in a variety of fields, including insulating electrical antennas, producing impact-resistant pulleys, making storm protection equipment, using them in water vehicles, and even providing bulletproof equipment.

Familiarity with the raw materials used in the production of refractory bone fiber will be a great help to better understand its properties. Bone fibers, as mentioned, are made from a combination of cellulose paper and phenolic resin, in both black and dark brown colors. This refractory material is one of the most popular industrial insulations on the market due to its reasonable price and many advantages in bone refractory fiber. These fibers have a positive performance in different environmental conditions and the dryness or humidity of the environment will not change their efficiency. Also, the hardness of these fibers has made it possible to turn them. The resistance of this product to pressure and abrasion is also due to its stunning physical properties. On the other hand, the chemical resistance of refractory fiber against various oils and solvents increases its durability and thus increases the life of parts. But most importantly, the electrical properties of these fibers are evaluated very positively at high voltages, and this has provided the most use of refractory bone fiber in the field of electrical insulation of equipment. Of course, the thermal tolerance of this product is also acceptable and is about 120 degrees Celsius.

It is recommended to read the bone refractory article from Pars Refractory website for more information about this refractory material.

The extraordinary properties of bone refractory fiber have given it wide applications in various fields of industry, but with 

Due to its stunning electrical and mechanical properties, the most common use of refractory fibers is in the electrical industry and for the electrical insulation of low-pressure and high-pressure electrical equipment. Of course, the advantages of this product are also used in the insulation of transformers, power generators and alternators.
