Selection and application of asbestos cord for furnaces

Asbestos cord was invented only for thermal insulation. As part – Mineral threads that are eventually split into fibrous. The cord consists of a core who wore yarn. It is important to correctly pick up the type of product for use in the furnace. Mount the asbestos cord is quite simple using the instruction.

Pros and cons

Asbestos cord for fire-burning furnaces, which allows you to use it as thermal insulation. Material withstands up to + 400 ° C. Asbestos cord applies even during the construction of missiles.

Selection and application of asbestos cord for furnaces

The main advantages:

  • It is not afraid of temperature differences and humidity – natural fibers repel water;
  • The diameter may vary within 20-60 mm, while it is flexible, can adjust any form;
  • withstands vibrations and similar impacts without deformations and integrity disorders;
  • The product is very durable, it does not break at high loads – to improve wear resistance, the cord is wrapped by reinforcement;
  • It has available cost.

All the advantages of the material make it quite suitable for use in the furnace. However, there are consistentings, they are important to take into account. Asbestos cord known for a long time, he loses against the backdrop of newer materials.

Basic Disadvantages.

  1. The furnace sealant serves about 15 years, and then begins to highlight microfiber in the air. Breathe them harmful, so asbestos cord needs to be changed quite regularly.
  2. High thermal conductivity. The cord is heated when using the furnace and it is important to take into account.
  3. It is impossible to break asbestos cord, and dust from it should be disposed of. Small wreckage of material can fall into the respiratory tract and provoke various diseases.

Avoid unpleasant situations associated with the cord,. For this it is important to correctly use the material, follow safety rules. You also need to choose the right view of the stove cord so that it can withstand all the necessary loads. Asbestos material is quite affordable and common, which attracts builders and home masters.

Types of cords

There are several options for the execution of this material. Asbestos cord may differ depending on the destination. For the furnace, only 3 types are suitable. Others simply will not be able to withstand the alleged loads.

  • Chaon. General purpose cord is made of asbestos fibers, which are woven into polyester, cotton or viscose. This allows the use of material as thermal insulation. It is used in the manufacture of heat networks, boilers and other thermal equipment. Differs good resistance to bending, vibrations and stratification. Operating temperature should not exceed + 400 ° C. It is important that the pressure remains in the range of 0.1 MPa. In systems with high load, this type of material cannot be applied.

  • Chap. Cotton fibers or asbestos from above wrapped the yarn thread or the same main material. Temperature norms are the same as the previous species. But the pressure must be no more than 0.15 MPa. This is already a good solution for utility and production networks.

  • Shau. The inner part is made of a down cord, and from above – a winding of asbestos filament. The optimal solution for sealing coke ovens and other complex equipment. The maximum temperature is the same as in other species, but the pressure should not exceed 1 MPa. The material does not swell and does not decrease during operation. This avoids many unforeseen situations.

Types of asbestos cord have different limit load. There are other varieties of material, however, they are not suitable for use in the oven. From this list it is desirable to stop your choice on Shau.

Asbestoset sealant will best cope with the task and protects from unpleasant situations.

Manufacturers and brands

German company Culimeta is very popular. Her products have the perfect price-quality ratio. You can pick up asbestos cord from:

  • SuperSilika;
  • FireWay;
  • SVT.

These manufacturers have proven themselves among professional builders. But the glue is better to take from thermic, it withstands to + 1100 ° C.

How to use?

Modification Shau is best suited for the oven. Material persistent, does not rot, resistant to biological influences. Application of the cord is simple, you just need to act carefully and gently. Seal the metal furnace or door on it using fire-resistant asbestos as follows.

  • Clear surface from pollution.

  • In the groove evenly put the heat-resistant glue. If there is no place for the sealer, then just highlight the desired area to install the seal.

  • Lay cord from top to glue. In place of junction with sharp knife to cut over. The presence of gaps are unacceptable.

  • Close the door so that the sealer suggested well. If the material is not on the door, then the surface is still important to press.

After 4 hours, you can drive the oven and check the quality of the work done. The diameter of the cord must correspond to the groove on the furnace. Thinner material will not give the desired effect, and the thicker will prevent the door closing. If you need to compact the cooking part of the furnace, it is pre-removed.
