How Much Do You Know About Emery

Nail trimming is something we are all familiar with, and it is a good habit to trim your nails regularly, which not only keeps our hands healthy and hygienic, but also helps protect our nails. However, in the repair process, imperfection is the norm. That's why we often use mini nail emery to round out our nails until they meet our expectations. However, do you know what material the file is made of? ---That's the emery.

What is mini nail emery?

 

There are two kinds of emery, one is artificial, also called silicon carbide, and the other is natural, also called garnet. So what's the difference between the two?

 

Natural emery garnet, a non-metallic abrasive, varies in hardness from 6.0 to 8.0 according to iron and aluminum content, and in different colors, including black, green, and red. Its main uses are surface pretreatment for sandblasting and rust removal, water cutting abrasives, emery floor aggregates, and sewage treatment filter materials (that is, garnet filter materials). Because it is a natural mineral, the price of natural emery is also cheap.

 

Artificial emery, also known as silicon carbide, has a molecular formula of SiC and is available in green and black.

 

  • Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp.
 
  • Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and smelting at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. So what are the main uses of silicon carbide? Why do nail files use this material?

 

Why do nail files use emery?

 

Traditional nail files are made of emery and have two main sides: one for polishing the nails and the other for smoothing the nails. So, are there other uses for emery?

 

What are the other uses of emery?

 

  • Abrasives - mainly because silicon carbide has high hardness, chemical stability and certain toughness, so silicon carbide can be used to manufacture bonded abrasives, coated abrasives and free grinding to process glass and ceramics, stone, cast iron and some non-ferrous metals, hard alloys, titanium alloys, high-speed steel tools and grinding wheels.
 
  • Refractory and corrosion-resistant materials---mainly because silicon carbide has a high melting point (decomposition), chemical inertness and thermal vibration resistance, so silicon carbide can be used in abrasive tools and ceramic products firing furnaces. Shed plates and saggers, silicon carbide bricks for vertical cylinder distillation furnaces in zinc smelting industry, aluminum electrolytic cell linings, crucibles, small furnace materials and other silicon carbide ceramic products.
 
  • Chemical use - because silicon carbide can be decomposed in molten steel and react with oxygen and metal oxides in molten steel to generate carbon monoxide and silicon-containing slag. Therefore, it can be used as a purifying agent for smelting steel, that is, a deoxidizer for steelmaking and a structure modifier for cast iron. This generally uses low-purity silicon carbide to keep costs down. At the same time, it can also be used as a raw material for the manufacture of silicon tetrachloride.
 
  • Electrical use - used as heating element, non-linear resistance element and high semiconductor material. Heating elements such as silicon carbide rods (suitable for various electric furnaces operating at 1100-1500°C), nonlinear resistance elements, and various lightning arrester valves.
 
  • Others are formulated into far-infrared radiation coatings or into far-infrared radiation dryers for silicon carbide plates.
