Use of Industrial Abrasives
There are a number of different industries which will use abrasives in their manufacturing processes and the chemical and physical makeup of them will vary from one to the next. As well as many industries using abrasives to polish items others use them for grinding, honing, buffing, sanding, cutting, drilling and sharpening.
As mentioned previously most industrial abrasives today are made from hard minerals that have achieved a rating of seven or above on the Mohs scale. This scale is used as a way of testing and classifying just how hard a mineral is. Whilst there are other abrasives used for industrial purposes today which are made from synthetic stones.
These synthetic stones often have both the physical and chemical characteristics that you would find in minerals which occur naturally. However, they are not able to be classified as minerals as they have not actually been constructed naturally.
There are numerous types of minerals and synthetic stones being used to make abrasive materials and the most commonly used of all is diamonds. These are not only some that is formed naturally but can also be synthetically produced as well. Those that are made naturally and which are then mined for are often constructed from corundum. Whilst those that have been synthetically produced will be constructed from bauxite.
Diamond is one of the hardest abrasives known to man, but there are plenty of much softer minerals which can be used as an abrasive. One such soft mineral is calcium carbonate and this is often used as a polishing agent in toothpaste. It is this mineral in your toothpaste which helps to improve the whiteness of your teeth.
There are a number of different factors to be taken into consideration and these will affect just how effective the industrial abrasive is. The main one of these is the size of each grain that is used in abrasive methods. The actual size of each piece will vary from method to method. Some pieces are as little as 40micrometers whilst the largest pieces of abrasive grit (grain) will be no more than 2mm. In order to get the right size pieces of grit for use in industrial abrasives the minerals or synthetic stones will be crushed. The actual piece of the mineral or synthetic stone which comes into contact with the surface is very small this means much more pressure can be placed upon it.
When industrial abrasives are being used the force which is applied to each of the grains that make it up will cause part of the item on which they are rubbing to break away. But not only does the surface of the item begin to wear away so does the surface of the abrasive and this means that after a period of time the actual abrasive will need to be replaced.
