Definitions
- the invention relates to a scraper for Beschabtation and / or cleaning, in particular for beschaberung and / or cleaning of the production and / or treatment of a fibrous web serving units and preferably for Beschabtation and / or cleaning of drying cylinders, wherein the scraper of a composite material of a resin matrix material with embedded fibers.
- the invention has for its object to provide an improved scraper of the type mentioned above, which has a reduced coefficient of friction.
- the scraper contains a matrix material such as epoxy resin, in which copper and / or at least one copper alloy are mixed, and / or which is at least partially substituted by silicone-modified epoxide. Due to these features, the friction coefficient of the scraper is reduced. By reducing the coefficient of friction, the required frictional power for the scraper in the relevant unit, for example in the dryer group, can be reduced and thus the dimensioning and power consumption of the drives of the relevant unit can be reduced.
- the copper or the at least one copper alloy in the form of powder or flakes is mixed into the resin matrix material.
- At least one fiber material in the form of glass and / or carbon fibers is mixed into the matrix material.
- the matrix material is preferably epoxy resin which meets the required elasticity and durability requirements for such applications.
- scrapers with reduced coefficient of friction produced.
- the coefficient of friction By reducing the coefficient of friction, the required frictional force for the scraper in the unit in which the scraper is used, e.g. in the drying section, thus reducing the sizing and power consumption of the unit's drives.
- the reduction of the coefficient of friction is achieved in particular by the mixing of copper and / or at least one copper alloy in the form of powders or flakes into the resin matrix.
- a fiber material in particular glass and / or carbon fibers come into consideration.
- Another way to reduce the coefficient of friction is the substitution of parts of the epoxy resin matrix by silicone-modified epoxy resin.
