Graphite products are products made from natural graphite and artificial graphite. Common graphite products have various forms, including graphite rods, graphite blocks, graphite plates, graphite rings, graphite boats, graphite powder, etc. Graphite products are made of graphite, and its main component is carbon, which does not affect the human body. However, for people who are often exposed to graphite processing, pneumoconiosis may be caused by inhalation of graphite dust generated during processing. Let's take a look at what graphite products are.
What are graphite products?
Graphite products, as the name suggests, are products made of graphite. Because graphite has many excellent properties, graphite products are widely used in metallurgy, machinery, electric power, the chemical industry, textile, national defense, and other industrial sectors.
What are graphite products?
Anything made of graphite is a graphite product. Common graphite products mainly include:
1. Graphite rod
It is made of carbon, graphite, and a suitable binder by extrusion, baked at 2200 ° C, and then coated with a layer of copper. It is often used as an electric heating element in high-temperature vacuum furnaces.
2. Graphite block
That is, bulk graphite products, are mainly used in metallurgical furnaces, resistance furnaces as furnace linings and conductive materials, silicon carbide furnaces, graphitization furnaces, and other fields. The pencil lead in life is the graphite block used.
3. Graphite plate
Graphite plate is a graphite material composed of a metal core plate and a flexible graphite coil. There are two kinds of stamping type and bonding type. Lan heat sheets, valve core gasket replacement gaskets, etc. are ideal sealing materials, with a wide range of applications and strong sealing performance.
4. Graphite ring
Graphite rings are made of flexible graphite ribbon or flexible graphite packing, molded into ring-shaped products of different sizes. Used in compressors, pumps, valves, chemical instruments, meters, etc., as sealing materials for mechanical rotating parts.
5. Graphite boat
The graphite boat is a graphite mold, which is originally a carrier, which can put the raw materials and parts we need to shape or position into the graphite mold together, and then sinter at high temperature. The reason why it is called a graphite boat is mainly because it looks like a small boat. graphite container.
6. Graphite powder
Graphite powder is a kind of mineral powder, the main component is a carbon simple substance with, a soft texture, black-gray, with high-temperature resistance and electrical conductivity, can be used as a refractory material, conductive material, and wear-resistant lubricating material.
Do graphite products affect the human body?
Graphite is a form of carbon in nature, and its main component is carbon. Generally speaking, most graphite products are not harmful to the human body, but for graphite factory workers who often come into contact with graphite and process graphite products, graphite is dangerous.
The hazards of graphite products are mainly in the process of processing, loose graphite is easy to generate dust, the diameter of dust is small, and it is easy to be inhaled by people. Inhalation of large amounts of graphite dust can easily cause pneumoconiosis. People who are allergic to it may develop allergic asthma which may also cause other respiratory symptoms such as coughing, pressure, shortness of breath, etc. In graphite factories, crushing operations, drying operations, grinding operations, screening operations, packaging operations, transportation operations, and other processes are dust-prone environments. Workers who work in these environments for a long time should pay special attention to the prevention of pneumoconiosis.
