What is glass made of?
Glass is a common material in our daily lives and is widely used in construction, home furnishings, electronic products and other fields. So, what exactly is glass made of? This article will introduce in detail the raw materials and production processes of glass as well as hot topics and content in the past 10 days to help you fully understand the mysteries of glass.
1. Raw materials of glass
The main raw materials of glass include the following:
| raw materials | function | Proportion |
|---|---|---|
| quartz sand | Provides silica, the main component of glass | 70-75% |
| soda ash | Lower the melting point and promote melting | 12-15% |
| Limestone | Increase chemical stability and hardness | 10-12% |
| Other additives | Such as alumina, magnesium oxide, etc., used to adjust glass properties | 1-3% |
2. Glass production process
The glass production process mainly includes the following steps:
1.Ingredients: Mix quartz sand, soda ash, limestone and other raw materials in proportion.
2.melt: Put the mixed raw materials into a high-temperature furnace and heat it to about 1500°C to completely melt it.
3.Forming: The molten glass liquid is formed by blowing, rolling, drawing and other methods.
4.Annealing: Cool the formed glass products slowly to eliminate internal stress and improve stability.
5.processing: Cutting, polishing, coating and other post-processing of glass.
3. Hot topics and content in the past 10 days
The following are hot topics and hot content related to glass in the past 10 days:
| topic | heat index | Main content |
