Sandpaper is an indispensable thing, and it is widely used in various mold models such as mobile phones, cars, and wooden products. Moreover, sandpaper plays an important role in the coating construction process. Sandpaper is generally divided into dry sandpaper, water sandpaper, and sponge sandpaper. Their common feature is the use of binders to bond different abrasives and sandpaper matrices together.

Sponge sandpaper:

Sponge sandpaper Sponge sandpaper is the primary component of sanding technology, suitable for polishing smooth parts, and various materials are available. Sponge sandpaper sanding technology has the characteristics of high production power, good surface quality processed, and low production cost. Therefore, it is widely used in furniture production. The final surface quality of furniture products is closely related to sanding technology.



Dry frosted paper:

Dry sanding paper uses synthetic resin as a binder to bond silicon carbide abrasive onto latex, and is coated with an anti-static coating to make high-end products. It has the advantages of anti clogging, anti-static, good softness, and high wear resistance. A variety of fineness options are available, suitable for polishing metal surfaces, wood surfaces, putty, and coatings. Dry sanding paper is generally made of special Kraft paper and latex paper, natural and synthetic resins as binders, and advanced high electrostatic sand planting process. This product has high grinding power and is not easy to stick chips, and is suitable for dry grinding.

Dry sanded paper is also known as dry sanded paper. Dry sandpaper has a large space between the sand particles, and the debris produced is also large. During its use, large debris in the open space will fall off on its own, so it does not need to be used together with water. The sand particles are generally high-quality silicon carbide, and the paper base is generally made of latex paper, which has better flexibility and better heat dissipation during use, making it less prone to blockage. Dry sandpaper is widely used in various professions and professions such as wood processing, stone processing, precision mold polishing, synthetic material processing, and is widely used in furniture, decoration, and other professions.



Application of dry sandpaper in the construction process of wood wax oil:

In the process of wood wax oil construction, we often talk about using different mesh sizes of sandpaper when polishing wood, and here we are talking about dry sandpaper, not water sandpaper. The auxiliary materials provided by Cherishi during the wood wax oil construction process are water resistant sandpaper, with animal glue as the base and compound, and brown corundum as the abrasive. They are suitable for wood surface processing and wall decoration polishing. Specification: approximately 215 * 280mm.

Water frosted paper:

Water sanded paper, also known as water sanded paper, is a waterproof sandpaper that can be used with water grinding. The abrasive material of water abrasive paper is generally silicon carbide, and the paper base is usually Kraft paper. There are also relatively high-end ones, such as imported 3M water sandpaper, many of which are based on latex paper. The characteristic of latex paper is its good flexibility and stronger surface adhesion of sand particles, making it more durable, with more uniform particles and superior polishing effect.

The open space between the sand particles of water sandpaper is relatively small compared to dry sandpaper, and the debris produced by grinding is also small. When used with water, the debris will flow out with the water and maintain the sharpness of the sandpaper application surface. Assuming that water sandpaper is used for dry grinding, product debris will adhere to the open space of the sand particles, causing the surface of the sandpaper to lose sharpness without grinding force. And then it cannot achieve its intended use. Water sandpaper is widely used in professions such as stone polishing, hardware processing, mold processing, wall atomic ash polishing, car surface polishing, rust removal, and paint removal.



The application of sandpaper in daily life:

Water sandpaper also plays a significant role in daily life, as it can be used to polish the teeth of a comb. Some comb teeth are too sharp, and can be polished with sandpaper to make them round and smooth. Water sandpaper can be used for painting, and oil painting sticks can be used to draw on water sandpaper. The rough surface of sandpaper can better highlight the beautiful and delicate colors of oil painting sticks. Sandpaper painting is a suitable way for children to draw.

Assuming you don't pay attention to the maintenance of the wipers, especially when using them in dusty conditions, you will soon find that the wipers are fuzzing and cannot clean the glass, leaving many fine water marks. There is no need to rush at this time. You just need to find a piece of water sand paper of No. 2000 (No. 1500 is also OK, and water sand paper is generally available in Hardware store), and carefully polish the two sides of the wiper film back and forth. Especially when comparing the areas where scratches are left on the glass, polish them a few more times so that the wipers can return to their original state.



Differentiation between dry sandpaper and water sandpaper:

What is the essential difference between water sandpaper and dry sandpaper? Is it really like the literal meaning? Why does dry sandpaper not require water, but water sandpaper does? Water sandpaper has a smaller space between the sand particles and produces smaller fragments. When used with water, the fragments will flow out with the water, so it is best to use it with water. Assuming that water sandpaper is used for dry grinding, the fragments will remain in the open space of the sand particles, causing the surface of the sandpaper to become shiny and unable to achieve its intended function. And dry sandpaper is very convenient. The space between its sand particles is larger, and the ground debris is also larger. During the grinding process, due to the large amount of ground debris falling off, it does not need to be used together with water. Dry sand can be divided into commonly known red sand and white sand, with the difference being that the former is not treated with an anti clogging coating. Water sandpaper is ground slowly, but it is polished more smoothly (the finer the water sandpaper, the slower it is ground, it also shines, and is commonly used for oil grinding of high gloss products); Dry sandpaper grinds faster but coarser (the coarser the dry sandpaper, the faster and coarser it grinds, usually used for white wood grinding with sizes below 400, and for oil grinding with sizes between 400 and 800).

Water sanding paper is generally polished under water containing conditions, resulting in less dust and better working conditions. Although dry sanded paper has the characteristics of anti clogging, anti-static, good flexibility, and high wear resistance, it is heavily polluted by dust and requires the wearing of appropriate protective equipment during operation (although the strong function of dry sanded paper is also acceptable).



Common misconceptions in the use of sandpaper:

1. Worn sandpaper is equivalent to high-grade sandpaper

Old sandpaper means a decrease in cutting power and an increase in heat generation. Assuming you feel that the polishing speed is too slow, replace it with a new sandpaper, perhaps a decrease of one size.

2. The harder you press on the sandpaper, the faster it will be polished

Pressure only increases the wear and heat of sandpaper, and even burns the wood. Generally speaking, polishing only requires a very light pressure, allowing sandpaper and things to sell as labor, which is easy and extends the lifespan of sandpaper, and the speed is not slow at all.

3. Use a labeled sandpaper to the end

Many beginners only buy one size of sandpaper, which results in very low power consumption.

4. Polishing is a long and boring process

Assuming you have this feeling, it is generally because there is no obvious progress in the polishing process. This indicates that the sandpaper number you are using is too high or too old, and you need to replace it with a new one.
