Sandpaper - what you did not know exactly about it (interesting facts) Interesting and unusual facts about an ordinary sheet of sandpaper

Such familiar objects for us often open completely from the other side. For example, even if we talk about the simplest sandpaper, this is not just an abrasive, but a material that has an incredible history. If you did not know this, then we suggest that you familiarize yourself with very interesting facts and find out what is hidden behind a simple sheet of sandpaper.

Briefly: sandpaper is a material on which a layer of powder (abrasive) is applied, consists of a base (paper or fabric).

The history of abrasive

The first mentions of the usual "skins for scrapers" were found in the 13th century.

An unusual and new product was created, moreover, in the best traditions - in China. These were pieces of animal skins, which were preliminarily cut out and then glued with small particles of glass. Until now, no one knows what exactly became the prototype of the abrasive.

Even now, there are nationalities and tribes that use different materials for sanding with unusual surfaces. For the Polynesians, this is a dried skin from a shark, and for the tribes from the islands of Tierra del Fuego they use a hard shell of fruits of a certain type of wood.

An interesting fact is that in the 18th century, emery began to be made from a paper base on which broken glass was glued, but such an abrasive was not durable, could withstand no more than 1 hour of work, and therefore such material was called nothing else, like "glass paper".


Varieties of sandpaper

Emery, which is made on a paper basis, has a low cost, and retains its shape (does not deform or stretch), and the surface is suitable for applying even the smallest particles of grinding substance - this is its certain advantages.

But there are disadvantages of paper sandpaper, namely, that there is no special strength and resistance to water, rapid wear. Wrapping paper or newsprint is sometimes used to sand plastics.

Sandpaper in the modern world

Sandpaper - what you did not know exactly about it (interesting facts) John Oakay became the real inventor of such paper in its improved form.

He was an apprentice, and he guessed to replace expensive broken glass with sand, and simple glue with a thick substance made from resins. In 1833, the manufacturer began to organize the mass production of sandpaper. Then, in 1921, an abrasive material with waterproof properties entered the market. The innovation was so successful that Henry Ford became interested in it. Sanding with water resulted in a smoother surface.

But the invention was patented on June 14 in 1834 by Isaac Fisher, who also invented the silicon carbide grinding material from aluminum oxide.

The properties of the material have led to the use of sandpaper in the manufacture of car bodies.Today, work on giving the sandpaper improved qualities does not stop. The inventors came up with the idea of ​​using carbide instead of silicon sand.

These are crystals with sharp edges.

Urea is not very strong, and for this reason, during use, it will decompose into smaller fractions, but with the same sharp edges.

In this case, users receive eternal sandpaper with an incredibly long service life. At the moment, metal and glass are being polished with silicon carbamide, the surface will be perfectly smooth and also free of scratches.

Non-standard uses

Sandpaper - what you did not know exactly about it (interesting facts) People in the art world are known for their unusual attitudes towards the world. They use sandpaper not only to sharpen pencils, but also as canvas for paintings, sheets for writing memoirs, and even as the cover of their books.

Juan Miro, a Spanish artist, used sandpaper as a canvas, and after that this method of application became very popular, because it turned out to create voluminous and original drawings, thanks to which the paper shone through the strokes and spots.

This method is a strange, but rather original and unusual move. As far as the usual area of ​​application of sandpaper is concerned, it is incredibly large - the material can be used for sanding and sanding almost any surface.

Today, manufacturers of working tools widely use the principle of sandpaper - abrasive particles should be attached to a solid base. Drills, blades are sharpened with an abrasive, used to process holes.

They also often give furniture a "antique" look, and also treat skateboards to reduce the sliding effect of the board.

Designer Mandy has created unique small-sized sculptures that are made from a sheet of sandpaper. They show household items as interpreted by the artist, and such figures help to recreate a cozy, and at first glance, even a double bed, and sometimes beautiful shoes, a women's swimsuit or a children's slide. All figures have a peculiar sense of humor, what in everyday life for a person is comfort, softness, convenience and warmth, here acts as an antagonist.
