Glass Pure Molybdenum Electrode Polished Alkaline Washing Melting Glass

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.
