Method of selecting tungsten sand

Tungsten sand is an important material with extensive applications in industries, aerospace, electronics, and other fields. The selection of appropriate tungsten sand has an important impact on the quality and efficiency of industrial production. So, how to choose the appropriate tungsten sand? This article will introduce several methods for selecting tungsten sand.

1. Appearance method

The appearance method is a simple and feasible method for selecting tungsten sand. By observing the appearance of tungsten sand, its quality can be preliminarily determined. High quality tungsten sand should present a metallic luster, with uniform particles and no impurities or cracks. Poor quality tungsten sand, on the other hand, will exhibit a dark gray color, uneven particles, and even obvious cracks and impurities. Therefore, when choosing tungsten sand, a preliminary judgment can be made based on its appearance.

2、 Chemical analysis method

The chemical analysis method is a relatively accurate method for selecting tungsten sand. By conducting chemical analysis of tungsten sand, its chemical composition can be obtained to determine its quality. High quality tungsten sand should contain high tungsten content, and the content of other impurity elements should be low. The low-quality tungsten sand will contain more impurities, which will affect its quality. Therefore, conducting chemical analysis can more accurately determine the quality of tungsten sand.

III. Physical Performance Testing Method

The physical performance testing method is a commonly used method for selecting tungsten sand. By conducting physical performance tests on tungsten sand, physical performance parameters such as hardness, density, and thermal expansion coefficient can be obtained to determine its quality. High quality tungsten sand should have high hardness and density, while the coefficient of thermal expansion should be low. Poor quality tungsten sand, on the other hand, has lower hardness and density, and a higher coefficient of thermal expansion. Therefore, conducting physical performance tests can provide a more comprehensive assessment of the quality of tungsten sand.

IV. Application Performance Testing Method

The application performance testing method is a relatively practical method for selecting tungsten sand. By conducting application performance tests on tungsten sand, its performance in practical applications can be obtained to determine its quality. High quality tungsten sand should have good application properties such as wear resistance, corrosion resistance, and high temperature resistance. Poor quality tungsten sand will exhibit poor performance in practical applications. Therefore, conducting application performance testing can more accurately reflect the quality of tungsten sand.

In summary, selecting suitable tungsten sand is of great significance for industrial production. By using appearance method, chemical analysis method, physical performance testing method, and application performance testing method, the quality of tungsten sand can be comprehensively judged, and suitable tungsten sand can be selected to improve the efficiency and quality of industrial production.
