Phenolic filamentary fiber

Phenolic fiber

Phenolic fiberglass is made of fine, fine cotton or linen cloth, soaked in phenolic resin at high temperature and pressure. In this compound, cotton or yarn will act as a reinforcer, and the phenolic resin, called cresol formaldehyde, will be the adhesive. This product is also introduced with titles such as phenolic cotton fabric sheet and insulation sheet.

In general, the maintenance of the structure in various environmental conditions, chemical properties, high pressure and temperature tolerance up to about 538 ° C, and good mechanical strength, have been the main reasons for the widespread use of refractory materials to insulate industrial parts in various fields. On the other hand, refractory materials are resistant to most acids and bases and neutralize the pressure on the parts. This, in addition to increasing the life of the components, significantly reduces energy loss.

In this article, we intend to study phenolic filament refractory as one of the most popular refractory products in the industry. But first, we will have an overview of the components of this refractory material to make it easier for us to understand its properties. As mentioned earlier, phenolic fiberglass is made from fine-textured linen fabric and phenolic resin at high temperatures and pressures.

Linen fabric is produced from plant fibers of the same name, which can be grown in various climatic conditions and is widely used in the textile industry. The use of natural flax fibers in today's textile industry, where synthetic fibers are often used, shows that this product still has a good position in the modern fiber industry.

In ancient times, the only use of this plant was to produce warm clothes for cold weather, but now, with the change of lifestyle and taste of people, the use of linen has changed and almost all parts of it are used for various purposes. The woody texture of the flax trunk, which in the past was neglected and discarded, is now used to build animal dormitories as well as to produce chipboard. Flaxseeds today, in addition to being widely used to produce items such as paints, varnishes, cosmetics, etc., are a healthy food, known as flax, full of omega-3 fatty acids and have their own fans. Finally, flax fiber itself, which is obtained from the trunk and outer part of the flax stem, is widely used in the textile industry. In previous years, the main use of flax fiber, in addition to the production of warm winter clothing, was the production of strong ropes. Today, however, these fibers are used in a variety of fields, including geotextiles, composites, and refractories.

The reason for the great popularity of flax fibers among various industries is its easy assembly, chemical tolerance to most acids and dilute alkaline solutions, its optimal mechanical resistance during spinning and its remarkable elastic properties. Light linen fibers, on the other hand, can withstand up to 120 degrees Celsius. It should be noted here that although there are commonalities in the chemical structure of these fibers with cellulose cotton, the two are not the same.

To make phenolic filament refractory fiber, flax fibers must be impregnated with a phenolic resin called cresol formaldehyde. To produce this raw material, pressurized layers of paper, cotton or glass are impregnated with synthetic resin at high temperatures.

Phenolic is a versatile material with very low weight, impressive electrical properties and high strength that has various applications in the field of electrical insulation or even the production of bulletproof equipment. This product, which is also lighter than aluminum, is also used to make shockproof pulleys. On the other hand, the very low absorption of water in phenolics has made it an ideal option for insulating water vehicles. The resistance of this material to high temperature, abrasion, impact and corrosion of most acidic and alkaline solvents has expanded its use among various industries. By injecting the resin into phenolics, flame resistance is also added to its unique properties.

Now that we are a little more familiar with flax fibers and phenolic resins, as materials used in the preparation of phenolic filament refractory fiber, we can take a closer look at some of the most prominent properties of this refractory material. Phenolic fibrous fiber, as a popular member of the refractory family, is produced in various colors such as yellow, reddish brown, light and dark brown and has the following characteristics:

Having a minimum amount of water absorption
Good mechanical properties and resistance to tension and abrasion, and shock absorption
Resistance to weak acidic solutions
Can be stored indoors and dry
High heat resistance up to 150 ° C
Electrical resistance and stunning dielectric properties
Capable of drilling and punching
Capable of turning
