How much do you know about the production process of quartz glass?

The production process of quartz glass is as follows:

        1. Making melting furnace: There are two kinds of melting furnace: clay furnace and platinum furnace. In recent years, small platinum furnaces have been used for optical glass entering rare elements to maintain stable quality.

       2. Putting optical glass raw materials: After the melting furnace (especially the clay furnace) has been dried for a long time, put it into the melting furnace according to the special formula and select other raw materials to prepare for melting.

       3. Heating, melting and stirring: the heating conditions depend on the raw materials. However, various raw materials must be mixed evenly to achieve homogeneity.

       Fourth, cooling: long-term "Xu cold". However, the length of time also varies depending on the raw material, which is the most important process to ensure excellent quality.

       5. Split furnace and sorting: split the clay furnace, take out the massive rough embryo and select it.

       6. Check, test, and shape: Check or test its various functions item by item to ensure the excellent quality of quartz glass.

       7. Blocking and chamfering (trimming): block the rough embryos into small pieces and chamfer them according to their uses and standards.

       8. Press embryo forming: After heating and softening the rough embryo, press the embryo to form according to the standards of the engineering drawing. However, it is necessary to make or prepare various molds, tools and auxiliary materials in advance.

       Nine, passivation: annealing passivation, eliminate internal stress.

       10. Test and check: test the optical function and appearance of the pressed embryo. Optical quartz glass This product will become the blank of the downstream industry (optical component manufacturing and processing plant), and after continuous processing and grinding, it will become an optical component.
