Product Description

Molybdenum Melting Glass Molybdenum Electrode

 

1. Description of Molybdenum Melting Glass Molybdenum Electrode:

 

The surface of the molybdenum melting glass electrode is metallic bright silver-white, and it will turn dark silver-white or uniform gray when placed in the air at room temperature. Among them, the molybdenum electrode with higher purity has better color and less surface change. Molybdenum electrodes can also be divided into: polished molybdenum electrodes, bright molybdenum electrodes, alkali washed molybdenum electrodes, buffing molybdenum electrodes and other types according to the processing method. After the molybdenum electrode is machined, the surface color is brown or dark brown, but this is not the color of molybdenum oxide, but the comprehensive color of various impurity oxides contained in the molybdenum electrode. The lighter the brown and the better the color uniformity of the surface, the higher the quality. Conversely, if the surface is black with different shades of color, the electrode is of poor quality. A good quality molybdenum electrode remains silver-white in color after several months of application in a glass melting furnace.

4. Applictaion of Molybdenum Melting Glass Molybdenum Electrode:
 

1). Generation of platinum wire drawing furnace


Glass fiber is an important building material and electrical material, and the traditional production method of glass fiber is to use Pt-7Rh alloy as a tong pot, and pass a large current, so that the tong pot can reach a high temperature and melt the glass. However, the tong pot of Pt-7Rh is expensive and cannot achieve industrial mass production. According to the characteristics of glass electrofusion and the excellent characteristics of molybdenum electrodes, the use of molybdenum electrodes and natural refractory materials as a substitute for platinum drawing furnace can not only save the amount of platinum and rhodium, but also be more economical. At present, molybdenum electrode instead of platinum wire drawing furnace is a common method for producing glass fiber in China.

 

2). GRC fiber


Glass fiber reinforced cement (GRC) composite material is a new type of building material. Its reinforced glass fiber and cement have good compatibility and corrosion resistance stability. The fiber contains 10%~20% ZrO2, and its melting temperature Up to 1500 ℃, can only be produced by electrofusion. By preparing a giant molybdenum electrode, its effective conductive area is 2800~5000cm2, which can meet the production needs of GRC fibers, and the price is reasonable.

 

3). Molybdenum electrode for aluminum silicate fiber electric melting furnace


Aluminum silicate fiber felt is a high-quality high-temperature thermal insulation material. The melting temperature of its fibers is as high as 1700~1800 °C, which can only be produced by electrofusion.

 

4). Molybdenum electrodes for optical glass production


In glass products, the quality requirements for optical glass are very high. The light transmittance and uniformity of optical glass are important factors to examine its quality. The glass cannot be polluted and colored, and the melting temperature is only allowed to fluctuate ±2°C. Only by the all-electric melting method can high-grade lenses be produced. In the all-electric melting furnace, molybdenum electrodes are the key to the production of high-performance glass. By preparing plate-shaped molybdenum electrodes, the optical glass produced after special treatment is of higher quality.
