this time, let us know some knowledges about the sand cloth.
what is sand cloth ?
Sand cloth is made by using a binder to bond abrasive sand particles evenly to the bottom plate of a solid cloth. It is mainly used for grinding rust, paint or burr on the surface of metal workpiece and polishing the surface, and can also be used for grinding non-metallic materials such as bone products. The emery cloth products displayed on this website mainly include brown corundum soft emery cloth, 2 inch mini emery cloth round sheet and sand belt. The emery cloth can be cut into different shapes according to the different needs of customers, and can also be divided into machine emery cloth rolls and manual emery cloth rolls according to the different use scenarios. In short, it is for the flexibility of polishing products in daily use.
what are the applications of the sand cloth?
In the daily application of sand cloth, the most widely used is the use of sand belt. Because the grinding cost of the sand belt is low, it is mainly reflected in the following aspects:
1) The abrasive belt grinding equipment is simple. Compared with the grinding wheel grinder, the abrasive belt grinder is much simpler, mainly because the abrasive belt weight is light, the grinding force is small, the vibration is small during the grinding process, and the rigidity and strength requirements of the machine tool are much lower than that of the grinding wheel grinder.
2) Abrasive belt grinding is easy to operate and less auxiliary time. Whether it is manual or motorized belt grinding, the operation is very simple. From the replacement of the adjustment sand to the clamping of the workpiece being machined, it can all be done in a very short time.
3) The abrasive belt grinding ratio is large, the machine power utilization rate is high, and the cutting efficiency is high. This results in reduced tool and energy costs for removing the same weight or volume of material, and a shorter footprint.
4) Belt grinding is very safe, small noise and dust, and easy to control, good environmental benefits. Because the sand belt itself is very light, even if it breaks, there is no danger of injury.
Belt grinding is not as serious as the grinding wheel, especially when dry grinding, the grinding chips are mainly the material of the workpiece being processed, and it is easy to recover and control the dust. Because the rubber contact wheel is used, the abrasive belt grinding will not form a rigid impact on the workpiece as the grinding wheel, so the processing noise is very small, usually <70dB. It can be seen that from the point of view of environmental protection, belt grinding is also worth promoting
what is the main role of sand cloth ?
1. Polishing and grinding: the sand of the emery cloth is fine, and the rough surface can be slowly polished and polished to make it more smooth and flat.
2. Cleaning: emery cloth can be used to clean various material surfaces, such as metal, glass, etc.
3. Repair: emery cloth can be used to repair and restore scratched surfaces, such as furniture, car surfaces, etc.
what are the main skills in use of the sand cloth ?
1. Pay attention to strength: the sand of the emery cloth is relatively small, it is recommended to pay attention to strength when using, gentle to prevent damage to the surface.
2. Choose the appropriate emery cloth: different surfaces need to choose different thickness emery cloth, such as the metal surface can choose a finer emery cloth for polishing, and the surface with deeper scratches can choose a thicker emery cloth for repair.
3. Timely replacement: The surface of the used emery cloth will become smooth, and it can not continue to be effectively polished and repaired, and it is necessary to replace the new emery cloth in time.
4. Pay attention to safety: Pay attention to safety in the process of using the emery cloth to avoid the impact of breaking the emery cloth and injuring yourself.
In short, sand cloth is a very practical hand tool, which has a wide range of applications in polishing, sanding, cleaning and repair. When using, it is necessary to choose the appropriate emery cloth and pay attention to the strength to obtain the best results and ensure safety.
