The Most popular sanding paper in cases when you are working with wood material. Because wood has a rough surface to remove the master almost always use exactly such a thing as sandpaper. What is it? Sandpaper or coated abrasives is the abrasive material, the main purpose of which is to impart a perfect smoothness almost any surface.

Emery paper-based

Kinds of grinding paper quite a lot. However, the most widely only some of them. The most used was the emery glass-dust on paper or fabric basis.

paper grinding

If we talk about paper this item, it is often characterized by a relatively high density of the material. This is a very important parameter as it will determine what mechanical damage could withstand the paper. In order to increase the lifetime and range of use, sometimes the sanding paper can be done on a water-resistant base.

The advantages of this type of material.

  • Low cost of the material, especially when compared with extra sanding attachments, which are sold on a drill;
  • Using a type of sandpaper, you can not worry that in the process of work will take place elongation of the basics;
  • On the surface with sanding paper with a paper base can be applied spraying with the least abrasiveness during its production.

However, there are also disadvantages, which include poor resistance to wear and low strength inherent in the paper.

Fabric

For the production of abrasive paper with such a base is most commonly used cotton, which is pre-treated with a special resin. It is because of this method of production of tissue grinder is characterized by high resistance to water, improved flexibility, and is characterized by relatively high strength.

The disadvantages of such coated abrasives is the fact that cotton tends to stretch in use. The second disadvantage is the higher cost compared to other bases, since cotton is more expensive, in addition, for the production of necessary and special resin.

I Should add that in specialized stores currently sell a combination of the sandpaper. This emery lie at the heart of glued together paper and fabric materials.

Types of sandpaper according to the method of application grain

Sandpaper differ not only base, but also the type of grinding grain, which was used during creation.

  1. The First type is a paper with open coating. In the production process of this paper sputtering of grain shall be such as to cover up to 60% of the area of the skin. The benefits of this class include the fact that during operation it will not become clogged with debris due to the presence of large gaps between the grains of abrasive. Most often, this type of sandpaper is used for treatment of wood surfaces or surfaces with medium density.
  2. The Second type is a closed coating. This paper assumes that the whole basis of the skins are covered by a dense layer of grain in the production. The use of this class of grinder is ideal for cutting hard surfaces, but use it very carefully because it clogged very quickly.

The Abrasive grains for sandpaper

Today for the production of such paper or nozzles on the drill uses a different abrasive grain. On this basis it is possible to distinguish 4 different types of material:

  • Ceramic abrasive. This type of abrasive is one of the most solid, and therefore it is used for rough processing of wood material. It is available in the form of special tapes.
  • Silicon Carbide. This type of grain has a low strength and medium wear resistance. The application area of the material grinding of body metal, fiberglass, etc.
  • Aluminum Oxide. This type belongs to is very fragile, as by mechanical action breaks down very quickly. However, this disadvantage can be an advantage, since the damage will form new sides for sanding, so the sandpaper can be used much longer.
  • Pomegranate. Often paper with such an abrasive member is used for treatment of different wood species. This abrasive is considered to be one of the mildest, and therefore its resistance to wear is very small. To work with him, you must have a lot of patience, because the process of polishing this paper is very time-consuming.

Marking sandpaper

Designation of coated abrasives is regulated by GOST. In this document as the primary parameter specifies the grain size, which is denoted by the letter P, and the limits for this parameter are numbers from 12 to 2500. It is important to understand that the larger the specified number, the smaller the grain size on the paper. It is also worth noting that in some former Soviet republics used the GOST of the USSR. In this casethe marking will indicate the number of 20-N. In this case it is important to know that listed tens of microns grinding. If you want to specify just the number of microns, the marking will look like this: M20. A rough classification of types of coated looks like this:

  • For the most rough treatment of the material using sandpaper type P22, R24, R36 80-N, 63-N, 50-N;
  • For a simple rough surface treatment is applied grinding marked P40, P46, P60 40-N, 32-N, 25-N;
  • To make the primary grinding the desired surface, using paper stamps P80, P90, R100, Р120 20-N, 16-N, 12-N, 10-N;
  • In order to complete grinding of the material and give it the perfect smoothness you need to use the sandpaper marks Р150, P180 8-N, 6-N.

Size sanding paper

Dimensions coated is determined depending on its granularity. Sandpaper with a measure of grit 50, has a width in 720, 750, 800, 850, 900, 1000. This indicator is measured in millimeters. Paper with such parameters width and grit is produced in rolls with a length of 30 meters. It should be noted that with R50 and a width of 1250 mm, coil length is reduced to 20 meters. For sanding paper GOST 6456-82 defines all sample sizes, the rules of production and acceptance.

Production

The production Technology of this product lies in the method of applying abrasive onto the substrate. For this operation there are several methods. It may be a mechanical method of application or the option with application of an electric field. Every manufacturer of grinding paper chooses what method to apply the abrasive. It is also worth noting that an important factor in the production will be and the choice of confounders. They may be different brand or type. Also the cords will depend on the strength and mode of operation of the sandpaper.
