During construction work, various types of asbestos tapes are often used. Asbestos fibers have a large number of useful properties, including increased fire resistance, a high level of strength, flexibility, and resistance to stretching. Today we will analyze the main types of these tapes, and also talk about what their main features are.

Peculiarities

These insulating tapes are made from chrysotile asbestos. Its fibers are ideal for the manufacture of such building materials, as they have increased elasticity . Such products have strictly fixed dimensions. At the same time, for each individual variety, its own specific dimensional values are established. Insulation materials are sold in large rolls, in which the fabric can be divided into smaller pieces.

In this case, the number of individual pieces should not exceed 5.

Views

Asbestos tapes can be of many different types. Let's highlight some of the most common models.

LAE-1

This asbolant is considered to be a fairly reliable insulating material. It is able to retain all its original beneficial properties at temperatures up to +400 degrees . This electrical insulating variety is often used to reliably insulate cables, a variety of electrical appliances. LAE-1, as a rule, is sold in rolls of 50 meters. The width of the material can be 2.5, 3 or 3.5 centimeters. The thickness of the product ranges from 0.35 to 0.5 millimeters.

LALE

This type of asbestos tape is also called asbolavsanovy. It is made from asbestos using a special binder, which is polyester lavsan. The ribbon is presented in the form of plain weaving products . It can easily withstand temperatures up to +200 degrees.

The model has increased resistance to excessive moisture. Even with constant exposure to water, it will not lose all its beneficial properties.

LAT

This tape belongs to thermal insulation materials. It has a braided structure. In the production of this variety, both chemical and natural ingredients are used. Often, it is LAT that is used to insulate pipelines and cables.

How to choose?

When choosing, remember that different types of asbestos tapes can only be used for specific purposes. So, if it is necessary to make reliable electrical insulation, then preference should be given to the LAE-1 and LALE models . If you need to produce high-quality thermal insulation of various structures, then you should purchase LAT asbestos-cement tape.

And also before purchasing such an insulating material, you should pay special attention to the dimensions. The choice in this case will depend on the type and area of the structure being processed . You should first unpack the roll and check the tape for damage. Serious defects include, first of all, metal inclusions. However, they should not be confused with the usual dark spots that are characteristic of asbestos itself.

Applications

These construction tapes are widely used, as a rule, to ensure proper thermal and electrical insulation of appliances. They will be a good option for the construction of chimneys and when processing furnaces . These products prevent the penetration of smoke into the room, and also provide good insulation of all stove parts from possible penetration of air masses. In this case, the core will form the basis, it is it that is upholstered with asbestos tapes.

They are quite often taken to insulate various cables . Some varieties are used as brake linings, which are located in friction and brake assemblies. Often they are additionally reinforced with thin brass wire.

How to use it correctly?

In order for asbestos tapes to perform their functions, they must be properly secured. Next, let's look at how to use them to insulate the oven . First, you will need to unwind the roll of material. At the same time, thoroughly clean the oven door and its surface from all dirt. It is also necessary to remove all old insulating materials. If there is a specially designed groove in the structure, then a small amount of glue must be applied to it. The tape will be attached to this place further. This material is distributed around the perimeter of the area to which the adhesive was applied. Then, at the junction, the tape is cut so that a gap does not appear as a result.

In order for the material to be firmly fixed, it is necessary to tightly close the stove door, which will press the tape . It is recommended to heat the oven after 3-4 hours and check if the insulating material is firmly fixed. Sometimes asbestos tapes are used to close gaps in furnace equipment. In this case, you will first have to dismantle the structure, clean the brewhouse from other compounds and contaminants. After that, the cleaned part must be primed with a mass of glue and liquid. It is applied around the entire perimeter with a thin layer. On all areas where the composition is applied, the asbestos product is carefully glued. The sealant will need to be pressed firmly, without coming off, for 5-7 minutes. Later, the brew section is put back into the oven.

Existing cracks can be treated with clay or sealant.
