Refractory yarn is produced with two cross-sectional and round cross sections. Refractory yarns are made from a combination of materials such as ceramic fibers, asbestos fibers, fiberglass fibers, etc. These materials are just a corner of the refractory materials.
Refractory yarns are available in both twisted and woven forms.
In this section, we have an overview of refractory yarns composed of the fibers mentioned above.
Refractory yarn made of ceramic fibers:
This yarn has the highest amount of heat tolerance up to 1400 degrees Celsius, which makes it well resistant to heat shock.
Ceramic yarn has significant resistance to chemical corrosion and performs well in alkaline and acidic environments. Due to these advantages, ceramic refractory yarn is used in various fields such as refineries, shipping, steel mills, power plants, welding and aluminum mills. It has a lot.
Refractory yarn made of asbestos fibers:
This yarn is made of pure asbestos fibers that can withstand temperatures up to 550 degrees Celsius. This product has good resistance to rust and chemical corrosion and is impermeable to chemicals, oil and water.
Asbestos refractory yarn due to its mechanical limitations; It can be used in insulation of boilers and insulation of motorhomes.
Refractory yarn made of fiberglass fibers:
This fiber is one of the lightest fibers, which is also known as glass fiber. This product has a lot of strength and density if it is woven, but if this yarn is spun, it has more flexibility.
Fiberglass refractory yarn can withstand temperatures up to 540 degrees Celsius.
In general, the benefits of fireproof yarn include:
Good tear, tensile and abrasion resistance and good mechanical strength
Excellent performance in different weather conditions, high temperatures and maintaining shape and structure
Prevention of equipment corrosion against friction and the ability to control the pressures on the parts
Good resistance to electricity and has good dielectric properties
Stability against oxidation and chemical corrosion, acceptable performance in alkaline and acidic environments
In general, refractory yarns with a rectangular cross-section are called packing, and refractory yarns with a round and thick cross-section are called ropes, which are used for sealing, insulation, sealing, etc.
