Felt sheet: types, purpose, characteristics

Felt sheet is a material that has a low thermal conductivity, excellent air permeability and low weight. The use of this material is carried out in the field of instrumentation, in the manufacture of machines as gaskets, seals and filters, which are located between the surfaces of metal. If this is the case, the sheets are protected from contamination and abrasion, they are not subjected to shocks and shocks. If it is a question of ecological purity, then it should be noted that felt sheet is harmless, so it can be used in the field of private construction in the insulation of residential and industrial premises. This material is made of natural washed sheep wool.

Varieties of material and their purpose

Coarse felt felts are used for glands, filters and gaskets, as well as for soundproofing materials. If we consider varieties of felt, then we can identify the plantar and shoe, which are used for the manufacture of platforms, insoles, shoes and soles. Podhomutovy and potnikovy felt is used in saddlery and saddle products. For the manufacture of yurts, the felt of the same name is used, but by builders it is used as a sound- and heat-insulating material. Felt sheet can also be needle-punched, in this case it is actively used in furniture production. But if the material has the form of a substrate, then it is laid under the linoleum. Another variation is felt. It is a felt made because of the fluff of rabbits and goats, it uses material for the production of headgear, outerwear, decorative items and bags.

Main characteristics

Felt leaf, as mentioned above, found its wide distribution today, this is due to the many positive characteristics that are inherent in this material. Among them we can distinguish:

• Ecological compatibility;
• thermal conductivity;
• Antibacterial;
• ease;
• Wear resistance.

Ecology is that toxic substances are not contained among the constituent elements of the material. Among other things, the material absorbs during operation, and afterwards neutralizes formaldehyde vapors, which makes it simply irreplaceable as an insulating material in private construction. Fur coarse felt is an excellent heat insulator. Sheep wool conducts heat poorly, and with an impressive volume of woolly fibers tightly interconnected, the material becomes a unique thermal insulation. It absorbs moisture, taking it out of the house, that's why the buildings where this material is used will never be damp inside the premises.

Felt boots are the warmest winter footwear is not accidental. Legs in them will never freeze, they will not get wet from the snow. Felt natural is also characterized by antibacterial properties. In the material, fungi and microorganisms are not planted, mold does not appear on the surface and inside. One can not help but note the lightness that complements the rest of the technical specifications. The material is highly wear-resistant, it does not suffer from abrasion, therefore for a long time the felt does not lose its characteristics.

Polishing wheels

A felt wheel is the most popular polishing material. It is made of high quality wool, which is pressed in the production process. Circles can be semi-grubby, thin-haired and coarse-wool. Quite often, when making felt wheels, dense grades of raw materials are used, as others wear out quickly. But thin-haired circles are used to handle critical parts of devices and machines. A semi-coarse felt felt wheel is used for polishing medical instruments, parts of precision measuring instruments and other things. In other cases, coarse-wool products are used. Polishing of non-ferrous metals is preferably carried out using soft felt wheels. Such materials work most efficiently at low speeds. The recommended parameters vary from 5 to 10 m per second. If the speed is too high, the surface will be harder, and the felt wheel will simply fall off it and will be wasted.

Additional information about felt circles

It is worth remembering that all felt grades get dirty very quickly, therefore, precautions should be taken. Circles should be kept away from dust and dirt. The dead circle should be closed if it is removed from the drive. It is usually wrapped in clean paper. On the felt wheel, mixing of powders or pastes should be avoided, but if you want to work with the dioxide series, then do not use another polishing powder on the felt wheel.

Recommendations of a specialist

The felt wheel for polishing can be made of thin plates that are cut from the bootlegs from old boots. The diameter of such a circle can vary from 5 to 25 cm, everything will depend on the drive used and the purpose of the circle.

Warming doors with felt

Felt technical is used today for insulation of doors. The material is breathable, so it can be used even in baths with high humidity and exposure to temperatures. The material should be rolled up, and on the side where the edge is visible, the roll is laid along the perimeter of the box. Fixation is carried out by a stapler or nails. Additional protection is not required. Technical felts can be used to insulate the whole door leaf, for this purpose sheets are used which should be fixed on the outer part. Furniture nails with beautiful hats should be fixed insulation, covering it with a skin substitute or any other material. The latter should be resistant to weathering.

Alternative options for using felt insulation

With the help of felt, not only the doors are insulated, but also the walls, the floor, and the floor of the ceiling. However, for the warming of walls to use this material is problematic enough, and the cost can be high. The price is indicated per kilogram, in this case you will have to pay 200 rubles, the final cost will depend on the density.

Conclusion

Warming of doors, as well as any other structures in the house, can be carried out with the help of technical sheet felt. This material has many advantages, you can use them in the home for floor and ceiling insulation. However, sometimes the material requires protection.
