On the market there are many types of sandpaper, the roughness depends on different types. To know that, buyers need to learn carefully about the information and the purpose of each sandpaper. The following article will answer information about what sandpaper is and what types of polishing sandpaper are on the market. From there, buyers know how to choose sandpaper that better suits their needs.
1. What is sandpaper?
Sandpaper is widely used in manufacturing industries because of its ability to polish and abrasive materials such as plastic, wood, metal, glass, ... Thanks to the use of sandpaper in production, the material surfaces are polish and smooth quickly.
Sandpaper is being used more and more because of its abrasive properties against most surfaces of the material. Sandpaper also has a very special structure and is classified into many types in production.
The structure of sandpaper
The structure of sandpaper is quite special with 3 components including sand, glue and fabric. Specifically:
Sandpaper: This is considered an important and indispensable ingredient in sandpaper. Sandpaper is an abrasive that helps to wear the material easily and effectively. On the market, there are many types of sandpaper with abrasive particles made of garnet, aluminum oxide, emery, alumina-zirconia.
Adhesive: The middle layer is an adhesive layer that binds the sand grains to the fabric to create a complete sandpaper. This adhesive layer is very strong in fixing the abrasive to create a firm bond when abrasive on the material.
Fabric part: As mentioned, the fabric part is the substrate for the abrasive particles to bond together. Some sandpaper manufacturers use paper instead of cloth.
2. What types of polishing abrasives are available?
On the market today there are many types of polishing sandpaper. Each type has its own characteristics. Types of abrasive paper are classified into categories based on the following factors:
Classification of sandpaper by sand
Sandpaper is graded based on the degree of sand from more or less. This allows the sandpaper to do the job quickly or longer depending on the sand. Specifically:
Sand P40: With this sand, sandpaper helps abrasion the rough surface of wood material with relative flatness.
Sand P80: Also a sandpaper with a sand level of P80, it polishes and wears the material a bit finer than the P40 sand.
P180 sand: Support abrasion of the surface of the material at a smooth level for effective PU lining.
Sand level 240: At this sand level, sandpaper helps to discharge PU lining during the entire coating process on the surface of the product.
P320 Sand: Unlike the above types, P320 sandpaper is discharge sandpaper, making the smoothness very high.
Sand P400: Rated as the type with the largest smoothing available today and can be used in cases where the product surface requires high fineness.
Sandpaper types have higher sand, the use process will make sandpaper quickly out of sand. Depending on the purpose of use and needs, buyers should choose the right paper to both save and effectively.
Sandpaper is classified by function
In addition to the classification of sandpaper, sandpaper types are also classified by function. Classification by function includes the following types of sandpaper:
Sandpaper: This is sandpaper specially produced for the operation of all kinds of sanding machines. Exclusively for smooth surface smoothing materials, especially natural wood materials.
Sandpaper rolls: The property of this sandpaper is that it is produced into small strips of paper like a separate roll. Use in the case of hand-held machines, typically an edge sander, a rise sander, or a burr machine.
Sandpaper: is a sandpaper commonly used for the purpose of sanding for a manual plane or can be used with a hand vibrator. Serving in the PU coating process helps to smooth the metal surface.
This article introduced sandpaper and sandpaper types. If you have a need to use sandpaper for the purpose of manufacturing and abrasive materials, you should learn carefully to choose the right product. Using the right sandpaper helps to save time and money and bring results quickly.
