Embodiment Construction

[0024] The production process of glass for protective glasses is as follows:

[0025] 1. Ingredients: prepared according to the names and parts by weight of main materials and auxiliary materials, and mixed evenly;

[0026] 2. Melting: When the high-temperature crucible is heated to 800 ° C ~ 1000 ° C, add the mixed raw materials, increase the furnace temperature to 1000 ° C ~ 1300 ° C, fire for 12-13 hours, and then reduce the furnace temperature to 800 ° C ~ 1000°C, firing for 3-4 hours.

[0027] 3. Blown glass bubbles

[0028] Equipment used: rolling bowl, blowpipe, cooling rack, air pump;

[0029] Preparation: After the raw material is melted, a layer of impurities will appear on the surface, which needs to be removed before blowing the foam, that is, scraping; then the blowpipe is heated. Insert the blowpipe into the crucible, rotate the blowpipe continuously, stick 130-150g of glass to the end of the blowpipe, take out the blowpipe, and blow into the material during t...

Abstract

A process for preparing the dark-color curved glass for the protecting glasses is disclosed. Its raw materials includes quartz sand (90-100 pts.wt.), broken glass (10-30 pts.wt), industrial alkali (35-40 pts.wt.), sodium nitrate (7-10 pts.wt.), arsenic trioxide (2-4 pts.wt.), Sb2O3 (0.6-1.2 pts.wt), borax (1-2 pts.wt.), V2O3 (2-8 pts.wt.), iron oxide (2-5 pts.wt.), and manganese trioxide (1-2 pts.wt.). Its advantages are low cost, simple process, and high protecting effect on preventing the irritation of strong light to eyes.

Description

technical field [0001] The invention relates to a process for producing glass, in particular to a process for producing dark concave glass lenses. Background technique [0002] In industries such as welding and steelmaking, workers need to wear protective glasses to work due to strong light irritating their eyes during technical operations. The glass of the protective glasses is dark glass, such as brown, dark green, dark gray. Most of the existing glass production lines produce flat glass for building decoration. At present, although the glass for protective glasses is also flat, because the lens glass requires a large arc, the bubbles blown by the general bubble blowing process are small, which is not suitable for protective glasses. surface requirements. If the pressing process is used for processing, the required equipment and processes are more complicated. Contents of the invention [0003] The purpose of the present invention is to provide a production method of ...
