What are graphite products?
Anything made of graphite is a graphite product. Common graphite products include:
1.graphite rod
It is made from carbon, graphite and appropriate binders, extruded, baked at 2200°C and then plated with a layer of copper. Commonly used as electric heating elements in high temperature vacuum furnaces.
2. Graphite block
That is, lump graphite products are mainly used in metallurgical furnaces and resistance furnaces as furnace linings and conductive materials, or silicon carbide furnaces, graphitization furnaces, etc. The pencil lead in daily life is graphite block.
3. Graphite plate
Graphite plate is a graphite material composed of a metal core plate and a flexible graphite coil. It has two types: punching tooth type and bonding type. Generally used to punch various gaskets, such as cylinder air cushions, drainage water level gauge pads, method gaskets, etc. Blue heat sheets, valve center gaskets, etc. are ideal sealing materials with a wide range of uses and strong sealing performance.
4. Graphite ring
Graphite rings are made of flexible graphite ribbons or flexible graphite braided fillers and are 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
Graphite boat is a kind of graphite mold. It is a carrier. We can put the raw materials and parts that need to be shaped or positioned into the graphite mold, and then sinter them at high temperature. The reason why it is called graphite boat is mainly because it looks like a small boat. Graphite container.
6. Graphite powder
Graphite powder is a mineral powder whose main component is carbon. It has a soft texture and is dark gray in color. It has high temperature resistance and conductive properties. It can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.
Do graphite products have any impact on the human body?
Graphite is a form of carbon found in nature. Its main component is carbon. Generally speaking, most graphite products are not toxic to the human body. However, for people like graphite factory workers who often come into contact with graphite and process graphite products, graphite is dangerous.
The main hazard of graphite products is that during processing, loose graphite easily produces dust, and the diameter of the dust is small and easy to be inhaled. Inhaling large amounts of graphite dust can easily cause pneumoconiosis. People who are allergic to it may suffer from allergic asthma, which may also cause other respiratory symptoms such as cough, nasal congestion, shortness of breath, etc. In graphite factories, processes such as crushing operations, drying operations, grinding operations, screening operations, packaging operations, and transportation operations are all environments that are prone to dust generation. Workers who work in these environments for a long time should pay special attention to preventing pneumoconiosis.
