Play DIY, with sanding process, that sandpaper must be an essential tool!
Can face a variety of kinds, is water sand is emery cloth what, small partners are completely silly and not clear ┑(~ ~)┍
So today, let's learn a few of our common sandpaper types, as well as their applicable fields and advantages and disadvantages.
Well, first of all, we should remember that our common sandpaper is basically divided into three categories (dry sandpaper, water sandpaper, sponge sandpaper).
One, dry abrasive paper
Dry abrasive paper, as the name suggests, is a kind of sandpaper that can be directly taken to grind.
Dry abrasive paper product characteristics: dry abrasive paper with synthetic resin as a binder to glue silicon carbide abrasive on the latex, and coated with antistatic coating made of high-grade products, with anti-clogging, anti-static, good softness, high wear resistance advantages. Available in a variety of fineness for polishing metal surfaces, putty and coatings. Dry abrasive paper is generally made of special kraft paper and latex paper, natural and synthetic resin as binder, and is manufactured by advanced high electrostatic sand planting process. This product has high grinding efficiency and is not easy to stick chips. It is suitable for dry grinding. Widely used in furniture, decoration and other industries, especially rough grinding.
Advantages: cheap and durable, can be used directly, high efficiency, grinding effect is obvious.
Disadvantages: When polishing, the dust is relatively large, the loss is relatively serious, and it can not be reused.
In addition to the common paper-based carrier, there are two special forms:
(1) emery cloth
After the carrier is changed from the original brittle paper into cloth, the service life is obviously increased a lot. Because the carrier is thicker, it is also more durable.
(2) flocking sandpaper
On the basis of the original carrier, a layer of fine fluff is added, which is often used with the machine.
Two, waterproof abrasive paper
Waterproof abrasive paper also has a great role in the production of the model, such as eliminating the water mouth of the part, grinding the part gap cut from the flow path, etc., sometimes you can also use fine sandpaper grinding to remove the gloss of the paint, remove the oxide layer of the metal parts, so that the metal parts issue the original metal luster. Rubbing oil on water sandpaper can give the wooden model a soft shine.
Features:
1. Waterproof sandpaper is mainly used for grinding and polishing of automobiles, furniture, leather, home appliance shell and mechanical parts. It has the characteristics of grinding with water, high surface finish of the workpiece, no dust pollution during operation.
2, coated sandpaper is suitable for wood, paint, soft metal and other soft materials grinding, with the use of no cutting, not easy to plug and other advantages.
3, water sandpaper for a variety of wood, non-metallic putty, glass grinding. It can also be applied to the beauty of fingernails and toenails.
Advantages: water does not remove sand, local fine grinding and finished furniture repair, generally water sand, when the need to add water grinding, grinding process because there is water dust, so basically no dust, the impact on the surrounding environment is relatively small.
Disadvantages: Grinding efficiency compared to dry sandpaper, a little low. It is used directly without water, especially easy to stick sandpaper, and the price is a little more expensive than dry grinding.
Three, sponge sandpaper
Sponge sandpaper is also known as sponge sand block, polishing grinding block, resin grinding block, abrasive grinding block, plastic grinding block, etc., is based on sponge as the matrix, and the abrasive sand is installed on the sponge, a polishing material
