Embodiment 1
[0023] Embodiment 1, a kind of continuous melting furnace for the production of corrosion-resistant quartz tube, with reference to figure 1 , including a continuous melting furnace 1, a charging cover 2 is installed on the top of the continuous melting furnace 1, a crucible 3 is arranged in the furnace cavity of the continuous melting furnace 1, and a feeding assembly is installed at the bottom of the crucible 3.
[0024] The blanking assembly includes two symmetrical blanking rollers 4 arranged close to each other. On the outer peripheral surface of the blanking rollers 4, a blanking gradient groove 5 is provided around the axis. The section of the blanking gradient groove 5 is semicircular and the blanking gradient groove The slot diameter of 5 is gradually increased from one end to the other end, and the two blanking gradient slots 5 cooperate to form a blanking hole 6, and a matching former 7 is fixed in the blanking hole 6, and the former 7 and the lower An annular blanki...
Embodiment 2
[0029] Embodiment 2, a kind of production method of corrosion-resistant quartz tube, it adopts the quartz tube that the production of corrosion-resistant quartz tube described in embodiment 1 is produced with melting furnace as raw material, and its preparation steps are as follows:
[0030] Step (1) Preparation of coating solution on the surface of the quartz tube: Soak the quartz tube in 10% hydrofluoric acid for 5 minutes to uniformly corrode the surface of the quartz glass, then wash it with pure water not lower than 10MΩ, and bake it at 100°C Dry, add 3g nano-silicon carbide and 1g dispersant polyethyleneimine to each 100ml of pure water and stir evenly to prepare a solution; use ammonia water to adjust the pH of the solution to between 10-11 so that silicon carbide is evenly dispersed in the solution. Nano silicon carbide solution;
[0031] Step (2) Lathe spraying of quartz tubes: place the dried quartz tubes on a rotating lathe, spray the nano-silicon carbide solution e...
Embodiment 3
[0033] Embodiment 3, in the production method of the corrosion-resistant quartz tube described in Example 2: the quartz tube in step (1) is soaked with 12% concentration of hydrofluoric acid for 7 minutes, so that the surface of the quartz glass is uniformly corroded, and then 12MΩ of pure water is used to Wash and dry at 120°C; add 5g of nano-silicon carbide and 2g of dispersant polyethyleneimine to every 100ml of pure water and stir evenly to prepare a solution.
