When buying sandpaper, you may see sand cloth, which looks similar to sandpaper, and 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, substrate is different
Abrasive paper is bonded to the paper substrate with an adhesive, such as kraft paper, latex paper, water-resistant paper, etc. Emery cloth is made by sticking abrasives to a cloth substrate.
2, the application range is different
sand cloth is mainly used in rough processing of metal and wood, mainly processed into sand belt and used with sand belt machine; Sandpaper is mainly used in metal, wood, paint, composite materials in grinding and polishing, hand-held sheet, back velvet rubber disc sand, sandpaper belt and other forms are suitable.
3, granularity is different
In comparison, the abrasive particle size of sandpaper will be finer, and the grinding effect is more delicate; The abrasive particle size of the abrasive cloth is relatively coarse, the grinding effect is relatively 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 ordinary sandpaper is usually cheaper than the emery cloth, but the price of high-end sandpaper is much more expensive than the emery cloth. And generally in the hardware store when buying sandpaper is more common, emery cloth is relatively less.
In fact,sand cloth and sandpaper have their own benefits:
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 relatively expensive, not very easy to buy, and the particle size is relatively large.
2, the advantage of sandpaper is that the price is relatively cheap, more types of models, grinding up more fine; The disadvantage is that the relative emery cloth is not so durable and easy to drop sand.
sand cloth and sandpaper have their own advantages and disadvantages, we can choose according to the workpiece material and grinding needs, it is usually recommended to use coarse abrasive cloth, fine abrasive paper.
