When buying sandpaper, you may see sand cloth, it looks similar to sandpaper, and it is also used for grinding and processing, but there are some differences between the two kinds of grinding tools, mainly reflected in the following aspects:
1. Different base
Sandpaper is the abrasive adhesive glued to the paper matrix, such as kraft paper, latex paper, water resistant paper, etc. Emery cloth is the abrasive glue to the cloth matrix, and some emery cloth base is made of paper and cotton together.
2. Different abrasives
Sandpaper and emery cloth are used as abrasive sand, which abrasive paper commonly used mainly silicon carbide, corundum and so on; Abrasive cloth and sandpaper are different, as abrasive there are artificial emery, artificial corundum, emery, silicon, quartz, light stone, iron oxide and so on.
3, granularity is different
In comparison, the abrasive particle size of sandpaper will be smaller and more delicate; The abrasive particle size of the sand cloth is relatively large and rough, but the grinding speed is fast and the efficiency is high, but the grinding accuracy is relatively not so high.
4. The price is different
The same specification model of the product, the price of sandpaper is usually cheaper than the emery cloth, and the general purchase of sandpaper is more common, the emery cloth is sold less.
Second, emery cloth or sandpaper is good
When grinding and processing, which sand cloth and sandpaper is good is a question that many friends will have, especially many carpenter friends, do not know whether to choose sand cloth or sandpaper, in fact, sand cloth and sandpaper have their own advantages:
1, the advantages of emery cloth is durable, not easy to drop sand, and can be folded to fold, will not break; The disadvantage is that the price is more expensive, not very easy to buy, and the exquisite is less.
2. The advantage of sandpaper is that the price is cheap, the types and models are more, and the grinding is more fine; The disadvantage is that it is relatively less durable and easy to sand out.
In general, sand cloth and sandpaper have their own advantages and disadvantages, can be selected according to the workpiece material and grinding needs, it is usually recommended to use coarse abrasive cloth, fine abrasive paper.
