    DESCRIPTION OF THE INVENTION This invention relates to a fir scraper (1) which in its basic embodiment consists of a handle (2), one or two blades (3) and devices (4,5,6) for mounting said blades. The blades can be made of spring-style plit which makes them somewhat flexible but twisted robust. A feature of the invention is that each blade has surfaces other than the scraper edge coated with grains or powder of a hard material, for example diamond, boron nitride, silicon carbide or the like. The big part here is that the blades become self-adhesive in the sense that no matter how worn they become, there are always one or two sharp edges because the edges are the part that is sanded down last. Another advantage is that the friction to the milled surface increases, which makes scraping more efficient.
    The fir scraper shown in the pictures contains two different blades, although the main requirement only focuses on a standard scraper with only one blade. This is to illustrate that the diamond powder may have different functions on different types of blades.
    One has a scraping blade type like a traditional fir scraper. The pictures show a variant with a blade consisting of bent spring numbers folded, but the advantages apply to all scraping paint scrapers that have a sharp edge. The advantage is that you have a blade that never really becomes a castle because the powder-coated surface is ripped down last and thus retains a sharp edge even after a period of use and grouting. If it is coated with diamond powder, it also has a better scratching effect because it simply has a better grip due to the friction. The high friction also means that paint that has not come loose is roughened up and has a matt surface.
    The second type of blade is a crackling variant which has the task of tapping the surface in a paint which has no adhesion to the substrate. Has gives the diamond powder a much greater friction. This means that the cracking force not only pulls straight down towards the surface due to the flexible spring plit, but also pulls the color surface forward in the scraping direction due to the high friction between the diamond powder and the color surface. In this way you can crack surfaces of paint that have a strong adhesion to the substrate even if the surface appears to be intact. The remaining color also automatically roughens its surface so that it becomes 1 matte and scratched. This is an advantage when the new paint is then to be applied, it is easier to fix and a layer between old and new paint is avoided. The layering may be due to dirt and grease present on the surface of the old paint.
    One problem is that the paint is stuck on certain surfaces while it has escaped from the surface in other areas. In the areas where the paint is stuck Or it is easiest to let the old paint remain while it is important that it is removed from the area with deadly adhesion. If it is not deposited there, enclosed air pockets are formed and the oven with a new surface on top is sensitive to bumps, winds and wind because the surface is not stuck in the ground. A solid and rigid blade tends to just slide over these surfaces without either cracking the surface or scraping it off as there is no flake edge to grasp, this often leads to being tempted to scrape more with one corner of the blade which can easily lead to damage to the surface.
    DOrfor Or det en fardel am bladet Or ndgot flexiblig den utterm delen før scraperkant sd att tryket distriban jaant Over hele skrapkanten, Oven am underlaget Or nOgot ojamnt. OjOmna underlag Or is exactly what you work with when scraping after some parts have been scraped off while others remain. Flexibility combined with a sharp edge and / or high friction Or a good way to remove old paint.
    The actual coating of the grains against std1 is usually done by means of binders in combination with pressure, heat or electroplating. The binders are usually ceramic or organic such as bakelite or phenolic plastic. The grain size has a standard published by FEPA, the Federation of European Producers of Abrasives. The grain size for this particular application can be thought to be somewhere between 25 and 500 pm. One can imagine a mixture of different sizes so that the slightly smaller powder-like grains for the most part serve to preserve the sharpness on the scraper edge while the larger grains are most useful as "clawing claws".
    In an alternative embodiment, the outermost part of the blade before the scraper edge is prOglats sd that the scraper edge has become wave-shaped (13). This gives a little extra pressure because only the road tops press against the surface of the paint.
    Another variant has baffles (14) in the trestles to make them stronger against the forces which will align the trestle. 2 PRIOR ART Diamond powder or similar grains of hard materials are often used on files, grinding wheels, cutting tools and drill bits. The technology for applying these powders to steel has developed greatly in recent times and continues to improve. It is often done with a combination of pressing and gluing the grains. Their abrasive properties are what you first and foremost want, so each grain should be lifted consisting of many sharp edges around the am. This creates a high friction to the body to be processed. The invention shows blades which precisely utilize the high friction to produce a scraping and scratching effect against the painted surface. It also shows a way of utilizing the hardness of the grains to preserve the sharp edge has something sharp, something that has traditionally been loaded with extra hard steel alloys in the blades and its scraper edges. With diamond powder on the outer part of the blades, it is possible to use more resilient steel alloys which can give the blades a certain flexibility which distributes the pressure better along the entire scraper edge.
    Usually a color scraper is made up of a handle that has a blade made of a hard stable alloy with a sharp edge. Normally the sharp edge is completely straight but there is also danger of wavy edges which gives an acute pressure on the surface under the wagon tops. But the vagueness is static and has no resilient adaptation to an uneven surface with varying adhesion of the color.
    After a period of use, the scraper edge loses sharpness and becomes blunt. There are replaceable blades, but a problem is that the slackness in the scraper edge comes slowly creeping in and you do not get a clear signal that it is time to change. Another is to find the new leaves when you vd1 need them, a classic thing to spend a farm dinner out in the country. It usually ends with Aker buying new ones and then only finding other types of paint scrapers with replaceable blades. said one is forced to change systems.
    Below is an example of a problem when using a standard paint scraper with a dull and stiff blade when scraping a house with painted standing wood panels: Since the fibers in the wood are vertical, the cracks on the paint usually become vertical. When you then scrape vertically, which can be natural, it is not uncommon for the blade to just slide over the area around the crack, despite the fact that the adhesion to the substrate is often the same right there. Often you laser it intuitively by scraping with one corner of the blade angled down towards the crack or changing the method of scraping horizontally over the paint crack. Both of these solutions can be preceded by the substrate, the horn scraping because it is black to control the force but it gathers in a single horn and the horizontal scraping because it goes across the fibers in the wood. These fibers are particularly fragile because they have been exposed to weather and wind due to the crack in the color. A blade that Or is somewhat flexible and also has its outer part coated with diamond powder distributes the pressure with a slight friction along the entire scraping edge of the blade. This means that even the vertical scraping gets a grip on paint that does not adhere to the substrate.
    Another type of scraper is the steel brush, which is a brush consisting of steel radar. This Or is a good tool for removing rust or other coating but not so effective in paint removal, at least not in cases where half of the paint surfaces are stuck and half have poor adhesion. This is because it largely lacks both the crackling and the scraping / snapping function mentioned above. The steel brush has a more nourishing function that can work in areas where the paint both lacks adhesion and has cracked surfaces. However, it can also be black to check the wear that can occur on the underlying surface.
    Furthermore, there are grinding machines or sandpaper that have a high friction against the paint. They lack the sharp edge that a scraper has and have a tendency to be filled with paint that has been sanded loose, which means that they stop working because the sanding grains are bathed in toner. You also risk that effect on the crackling blade type, but if you normally hail the scraper with a small angle so that it is the grains closest to the scraper edge that work the most. Since these grains are near the edge, the space between the grains is cleared automatically. When using a sanding machine with sandpaper, the entire sandpaper is parallel to the surface of the paint so that the sanding powder from the paint can not take the scales anywhere. 4 SUMMARY OF THE INVENTION A color scraper having the outermost portion closest to the scraper edge of the side of the blade or sides tackled by grains or powder of a material which is harder than the blade itself. The material can be, for example, diamond powder.
    A paint scraper containing steel leaves that crackle old paint layers in the areas where the paint has lost its adhesion to the substrate and which at the same time is gentle on the underlying surface. The crackling is strongly influenced by the high friction of diamond powder that has been applied to parts of one side of the blade. Farccm to crackle the paint layers, this leaf type also has a function of making the paint surface dull and a little rough. This means that the new color is easier to get a good fast when repainting.
    A color scraper containing stai leaves with scraping leaves that scrape off load-bearing color flakes and snap away color that lacks adhesion but has a bare edge and still sticks together with the rest of the paint layer. The sharpness of the scraper edge is preserved thanks to diamond powder that has been applied to the outer part of one or both sides of the blade. When the blade is flattened, it is always the edge with diamond powder that is worn down last, thereby forming a sharp edge.
    The scraper edge can be pressed into a wavy edge to give an acute pressure between the wagon tops of the blade and the color surface. With embossments (14) in the trestles, these can be colored so that they retain their shape even after a period of use.
    The combination of these functions makes the scraper both efficient and gentle. Gentle on the ground surface but also on the user as it provides varying muscle loads during use by alternately using the crackling and scraping blade type. The diamond powder enhances the effect of both of these functions.
