Platinum channel technology
Based on the good conductivity and high melting point of platinum, the application technology of medicinal glass platinum channel is designed, which can effectively reduce the pollution of glass liquid and the erosion defects of refractory materials. The platinum body directly heats the glass liquid, achieving precise temperature control of the glass liquid. The temperature error of the forming feed is controlled within ± 0.1 ℃, reducing the volatilization of boron; By using a platinum stirring rod to stir the glass liquid, the homogenization of the glass liquid is strengthened, stripes are reduced, and the yield of glass tubes is improved.
