The marble segment is a segment made of diamond and metal powder. The marble segment has the excellent characteristics of wear resistance, compression resistance, high strength and high hardness. It can cut and process different materials, so it is widely used in construction, stone , pharmaceutical, metallurgy, arts and crafts and other industries . The metal powder contained in the marble segment and its function will be introduced in detail below.
1:The type of metal powder contained in the marble segment:
iron powder
Iron powder is one of the metal powders commonly used in marble segments. It has good strength and toughness, which can increase the hardness and wear resistance of marble segments and improve their service life.
copper powder
Copper powder is a high-quality metal powder with good electrical and thermal conductivity, which can help the marble segment dissipate heat and avoid damage to the segment under high temperature and high pressure environment.
Aluminum powder
Aluminum powder is a light metal powder with high strength and corrosion resistance, which can help marble segments improve oxidation resistance and corrosion resistance, and increase their service life.
Tungsten powder
Tungsten powder is a high-density metal powder with extremely high hardness and wear resistance, which can help the marble segment to better cut and process high-hardness materials.
2. The role of metal powder
Improve hardness and wear resistance
The metal powder contained in the marble segment can be mixed with marble powder to improve the hardness and wear resistance of the marble segment and make it more durable.
Increased Strength and Toughness
Metal powder can increase the strength and toughness of the marble segment, making it more resistant to compression and bending, not easy to break, and prolongs its service life.
Improve thermal conductivity and heat dissipation
The thermal conductivity and electrical conductivity of metal powder can help the marble segment to dissipate heat and conduct heat better, avoiding damage to the segment in a high temperature and high pressure environment.
Improve corrosion resistance
The quality of the metal powder in the marble segment has a great influence on its corrosion resistance. The selection of high-quality metal powder with good corrosion resistance, such as copper and aluminum, can significantly improve the corrosion resistance of the marble segment.
Reduced sintering temperature capability
In the production process of the marble segment, adding a certain amount of metal powder to reduce the sintering temperature can lower the sintering temperature, improve the preparation efficiency of the segment, and reduce energy consumption. The following are several commonly used metal powders to reduce the sintering temperature:
Aluminum powder: Aluminum is a light metal with a low melting point, which can lower the sintering temperature. The amount of aluminum powder added is usually between 10% and 20%, which can effectively reduce the sintering temperature of the marble segment and improve the preparation efficiency.
Copper powder: Copper has high thermal conductivity, high electrical conductivity, and good plasticity. A certain amount of copper powder can be added in the preparation process of marble segments to reduce the sintering temperature and energy consumption.
Zinc powder: Zinc is an active metal with a low melting point. A certain amount of zinc powder can be added in the preparation process of the marble segment to reduce the sintering temperature and improve the preparation efficiency of the segment.
Magnesium powder: Magnesium is a light metal with good chemical reactivity. A certain amount of magnesium powder can be added in the preparation process of the marble segment to reduce the sintering temperature and improve the preparation efficiency of the segment.
In conclusion, metal powders that reduce the sintering temperature can play an important role in the preparation process of marble segments, improving the preparation efficiency and reducing energy consumption. Selecting the appropriate metal powder and strictly controlling its addition amount and preparation conditions can effectively improve the quality and performance of the marble segment.
