Diamond Pastes are abrasives made by mixing uniformly dispersed diamond particles, such as diamonds that have not been turned into gems or synthetic diamonds artificially created, in oil and fat.
It is characterized by its extremely stable polishing power.
Diamond Pastes are used as abrasives in a variety of applications.
For example, it is used to polish products made of metal and non-metal materials. For metals, it can be used for hardened and raw steel, cemented carbide, stainless steel, duralumin, aluminum, brass, and all hard and soft metals.
Non-metals include ceramics, ferrites, silicon and germanium semiconductors, glass, plastics, and precious and semi-precious stones such as rubies, sapphires, menorahs, and crystals.
It is also used for polishing plastic molds and metals, and for final finishes such as mirror polishing.
The paste form also makes it suitable for polishing complicated shapes that are difficult to work with due to their intricacy or curvature.
Diamond Pastes consist of fine diamond particles uniformly kneaded into a viscous gel, liquid or solid. Therefore, the content of diamond particles is not biased with each use, and the paste can be used as an abrasive while maintaining a certain level of polishing power. There are also a variety of diamond particle sizes to choose from to suit the material and application of the object to be polished.
Diamond Pastes are in paste form, so the abrasive does not flow down after application like liquid abrasives. Furthermore, because it can be used while maintaining its paste state, it can be used for polishing various parts and shapes, such as complex shapes and curved surfaces, which are difficult to achieve with other abrasives.
In addition, Diamond Pastes are available in oil-based and water-based types. Water-based Diamond Pastes can be washed off with water, making it easy to clean up after polishing. On the other hand, oil-based Diamond Pastes are suitable for use on areas prone to rust.
Diamond Pastes products are marked with #6000, etc. The "#xx" indicates the grain size, which is a measure of the size of the abrasive grains. The larger the number, the smaller the grain size and the more precise the polishing.
For example, #16, which has a small grain size, is used for rough finishing, while #10000, which has a large grain size, is used for mirror finishing.
As a conversion guideline, 15000/particle size = particle size, which gives a rough idea of the ratio. However, as mentioned above, this is only a reference value, as the notation may differ from manufacturer to manufacturer. If you want to know more details, please contact the distributor.
For Use in Industrial Processing
When using Diamond Pastes in industrial processing, use a diluent to dilute the concentration and hardness to suit the application. The paste is then applied to an abrasive cloth such as a felt pad or an abrasive plate such as a steel or glass plate, and the object is rubbed with the abrasive cloth or plate to apply the paste.
During this polishing process, the diamonds in the Diamond Pastes cause abrasion of the polishing cloth or plate. Therefore, when the useful life of the polishing cloth or plate is exceeded, it is necessary to turn it over and use the opposite side, or replace it with a new polishing plate.
For DIY Use
On the other hand, when using Diamond Pastes for DIY, etc., it is recommended to prepare an artificial woolen sheet in addition to the paste. Compared to other types of sheets, the fibers of artificial woolen sheets are more uniform, making them suitable for mirror finishing. Apply an appropriate amount of the paste to the woolen sheet and apply a hairline or circle finish. At this time, neither too much nor too little amount of Diamond Pastes can be used for polishing.
Since hairline finishing often produces straight polishing lines, circle finishing is recommended. Circle finishing is a method of polishing a specimen by spinning the hairline sheet within a certain area. It is possible to polish evenly and evenly.
The luster will increase as you continue to polish the specimen as if you were wiping off Diamond Pastes. The key point is to avoid wiping off the paste with cleaning agents while polishing. By using Diamond Pastes, even old rusty metals can be polished to a mirror finish as good as new.
