Description

I & olirbandag & R, The innovation concerns bandages for the production of vcm Orphan and cold insulation, preferably of pipes, who have the task of surrounding the body to be shielded to attach and protect the insulating materials.

Pipes or other bodies were previously with heat or. Provide cold insulation in such a way that insulating materials such as B. (ELas wool, slag wool, asbestos, porous plastic materials or the like with ties made of fiber cloth or paper, then an UmmMüate- plaster of paris. Kieselguhr or other materials in iger form asfbr & ate, in order after the mortar finally the beard coat with a fiber bandage like this. asa ickeln and to apply a smooth line which has been provided with a coat of various materials.

It is also known to use insulating materials in plastic foils to be packaged and also pipes with plastic bandages to cover, but the then still plastic was injected to secure the bandage wraps and to close the gaps between the support edges.

The bandages mentioned, however, still have the following deficiencies: When using fiber bandages as a lower bandage, the moist kieselguhr can penetrate. The like-porridge moisture in the actual primary insulation material, whereby the insulation ability is impaired, Bitumen-lined crepe paper strips are used as a sub-bandage unsuitable for the reason that the paper becomes soggy and pliable, which means that perfect insulation cannot be carried out.

Above all, the previous insulation is far too inadequate and too susceptible to humidity, dripping water and other weather influences.

Furthermore, such insulation are uneconomical because of their Manufacturing woven fiber bandages were used that were made from precious raw materials exist.

The known plastic bandages are in the form of smooth film strips produced the difficulties in laying, in particular due to their smoothness prepared so that it also happens that the edges are not always smooth on the surface lie on top and form gaps through which moisture, among other things. can penetrate. Attempts have been made to remedy these deficiencies by adding another plastic coating attached by spraying. Because of this additional work step and material consumption was the part of such Kunststeffbandagen as a result of uneconomic kali; canceled again.

Finally, it must be taken into account that the production of the known Bandages take a relatively long time.

In order to avoid the deficiencies shown, it is proposed according to the innovation that to use such bandages for the fastening and wrapping of the insulating materials, the strip of thin plastic, z. B. made of polyvinyl chloride, Polyamides, There are polyethylene or other plastics, the surfaces of which are fine embossed wear or are roughened as much as possible.

These fine embossings are preferably fine, in the surfaces of the strip indented grooves running parallel to the edges or regular grooves and / or irregular small and / or large-area embossments, grains or the like. educated.

The surface treatments ensure that the I! windings remain firmly on top of each other and thus cannot slide. The use of thinner relatively elastic film allows the bandage to be pretensioned to a certain extent can be wrapped, which means that the edges also fit snugly.

Another innovation is the equipment of the plastic films with the finest metal particles, such. B. aluminum powder that has either been incorporated into the film during manufacture or applied to one or both surfaces. Uia to identify certain pipelines own the Bandages, if necessary, different shades of color that men correspond, or are with corresponding colored markings, z. B. colored longitudinal bars, points or the like. Mistake.

By using the plastic bandages according to the innovation, it is achieved that the actual insulation body, e.g.

Glass wool or the like completely protected from the ingress of moisture and deformation is avoided. When using the plastic outer bandages there are a number of advantages, such as the saving of the outer textile bandage the protection of the gypsum-kieselguhr hard shell against washing out and penetration of moisture in resulting cracks and mechanical damage, saving paint and Protective paints, insulation against aggressive agents and protection against Weather influences, etc.

Claims (4)

Protection claims 1. Bandages for insulating purposes, characterized by Roughening or fine embossing of the surfaces of thermoplastics, in particular in strip or ribbon form. 2.
