Waterproof abrasive paper is loved by market consumers in daily life because it can greatly avoid dust pollution. Today we look in detail at how to choose water sandpaper.
How to choose the grit No. of the waterproof abrasive paper?
Generally speaking, the mesh starts from the finish of the surface to the desired finish.
Wood, leather and other fiber materials, it is difficult to achieve a very high number of mesh, can start directly from about 200 mesh, 800 to 1000 mesh can end.
Higher mesh wood leather polishing, the original material needs to be tight, oily wax, at this time the use of smooth hard surfaces such as glass, hardwood, brass, dipped in chemical filler, fiber bonding, can be further polished
Metal materials, starting from about 80 mesh, multiplied by 2 each time, to 1500 mesh or 2000 mesh effect is already good.
Higher mesh metal polishing, you can further use 3000, 5000 mesh sandpaper, but the effect is little, at this time should use polishing paste, with clean cloth, paper, etc., dipped rub, or use wool wheel to deal with; In addition, there is also the use of chemical polishes, the effect can reach the mirror, but it is harmful to personal health
Plastic, carbon fiber, glass fiber, stone products, the general original surface has a matte effect, sandpaper selection is limited, 800 mesh, 1200 mesh, 1500 mesh, 2000 mesh, etc., higher mesh should use polishing paste.
If it is to treat scratches, first of all to confirm whether the surface can be evenly thinned to the scratch depression, otherwise it is not recommended to local sanding, will produce a concave and convex feeling, should be coated with polishing paste as a whole, with wool wheel grinding, reduce marks
what is the sanding technique when you use the waterproof abrasive paper ?
First of all, start with low mesh, low mesh is not easy to block sandpaper, and powder is easy to collect, you can not use water grinding. Clean up the powder after each dry grinding, confirm whether the surface sandpaper marks are uniform and flat, if the effect is ideal, you can change to the next mesh number, at this time the grinding direction should be a larger Angle with the previous trace.
When the mesh number is higher, such as 800 mesh, you need to dip water grinding, the biggest point is that after each water grinding, in addition to washing the sandpaper, but also with a clean cloth or paper to clean the surface of the workpiece sand, to ensure that there is no low mesh sand pollution surface, and then change to high mesh sandpaper. At this time, it is still recommended to count one bucket per eye and set it aside after the end of work every day to reduce pollution to the environment.
The mesh number is high to a certain extent, such as 2000, 5000 mesh, it is necessary to observe the condition of the sandpaper at any time. It is useless to block sandpaper and then sand, but may lead to local overheating bonding; Once the sandpaper is blocked, it is necessary to carefully clean the sandpaper with water or oil.
