Ceramic fabric

Fiber ceramic refractory fabric

Currently, fiber ceramic fabric is the biggest competitor to asbestos refractory fabric for two main reasons. First, because none of the raw materials of this product, namely ceramics and fibers, are harmful to the environment and are completely environmental. And the second reason is that still, no refractory material has been able to achieve the high thermal tolerance of fiberglass ceramic fabric. The heat resistance of this product reaches up to 1260 degrees Celsius. However, scientists have estimated the temperature of 980 degrees Celsius as a suitable temperature for continuous and long-term use of this product. In addition, the fiber ceramic fabric is flexible, has high cohesion and strong texture. The physical properties and resistance of this refractory product to tension and abrasion have increased its popularity.

Sanat Pars Refractory Store is ready to provide consulting, sales and delivery of fiberglass ceramic refractory fabrics in various dimensions and thicknesses, all over the country.

As you know, fabrics made from refractory yarns have high heat resistance and pressure tolerance. Also, this member of the popular family of refractory materials is resistant to chemical agents and abrasion and maintains its structure in various environmental conditions. Low smoke emission is another important feature of refractory fabrics. Although these products have unique strength in thermal insulation, some properties such as chemical and physical resistance can be enhanced by adding or modifying their constituents. This will help to increase and target the use of refractory fabrics in various fields of industry. Among the types of refractory fabrics, a few of them have very special heat tolerance and one of these fabrics is fiber ceramic fabric.

Fiber ceramic refractory fabric, as its name implies, is made using ceramic fibers and fiberglass fibers and, in some cases, is reinforced with steel or steel wire to enhance strength. This fabric, which is one of the strongest refractory products, is made of a combination of alumina or ceramic fibers (80%) and organic materials and refractory fibers (20%). Fiber ceramic fabric, in addition to its high strength, is very light and has good flexibility.

The white fiber ceramic fabric is woven in the form of warp and weft, and for this reason, the final product is a smooth and uniform fabric. To prepare strong yarns of this fabric, which has a diameter of about 0.5 mm, first ceramic and fiberglass fibers are combined, and before using it for fabric weaving, to burn the fiberglass fibers protruding from the threads, it is abducted from the induction furnace.

To better understand the properties of this refractory fabric, we first take a brief look at the materials used in its production.

Alumina silicate fiber is a scientific title for ceramic fibers that in addition to optimal flexibility and low weight, has the highest heat tolerance among refractories produced to date. These fibers are produced from the melting of alumina and silica. This product is used for the production of cosmetics, food industry, glassmaking, and adhesive production. One of the uses of aluminosilicate in industry is the manufacture of industrial insulation.

Fiberglass or glass fibers, due to their chemical resistance and unique mechanical properties, have a great impact on improving the remarkable properties of fiberglass ceramic refractory fabric.

As mentioned earlier, the heat tolerance of fiberglass ceramic refractory fabric is 1260 ° C on average. But the exact amount depends on the type and amount of materials used in this fabric. This refractory fabric is produced in the form of three products: wireless, wired and foil, all of which are based on fiber ceramic fabric. Heat resistance 1260 ° C, specific to wireless fiber ceramic fabric; However, by adding steel, steel or incline wire to this product, along with increasing the tensile strength and mechanical strength, the heat tolerance in it reaches 1300 degrees Celsius. And if we cover the fabric with a layer of aluminum foil, this value will reach about 1320 degrees Celsius.

It is recommended to see the article of fiberglass refractory fabric, and the article of fibrous ceramic fiber fabric, from Pars Sanat refractory website.

The simultaneous presence of fiberglass and ceramic fibers in this type of refractory fabrics, causes significant features in it, which we will mention some of the most prominent ones:

The light weight is due to the low weight of the fibers used in this product.
Optimal flexibility of the final product
High heat tolerance; Although this fabric is able to withstand high temperatures up to 1260 ° C and in some cases, up to 1320 ° C, but experts have met the temperature of 980 ° C as a safe temperature for long-term use.
Low thermal conductivity and storage
Heat shock resistance
fire proof
Maintain structure and dimensional stability up to minus 50 degrees Celsius
High pressure resistance and neutralization, which leads to increased service life of parts.
Extraordinary mechanical strength and resistance to tension and abrasion
Excellent chemical resistance and compatibility with most acidic and alkaline materials (except hydrofluoric, phosphoric acids and concentrated bases)
Smooth and uniform texture, and desirable needlework
Environmentally friendly and a good alternative to asbestos fibers
Having such stunning features has led to the increasing use of fiberglass ceramic refractory in various fields of industry. Some of these applications are:

Production of gaskets for sealing in high temperature
Insulation and covering of wires, cables, pipes and exhaust
Insulation in nuclear power plants
Safety coverage in oil rigs and petrochemical industries
Insulation of equipment in power plants
Insulation of parts in the shipping industry
Production of expansion joints
Production of welding blankets
Construction of thermal curtains for furnaces
Texture of fireproof clothing including gloves and firefighting equipment
Casting industry
