What kind of product of glass is strange

The production process of glass includes: batching, melting, forming, annealing and other processes.

Main process: 1. Preprocessing of raw materials.

The bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed to dry the wet raw materials, and the iron-containing raw materials are treated with iron removal to ensure the quality of the glass.

2. Preparation of batch.

According to the designed material list, all kinds of raw materials are weighed and mixed evenly in a mixer. The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, boric acid, etc.

3. Melting. The glass batch is heated at a high temperature (1550 1600 degrees) in the pool kiln or crucible kiln to form a uniform, bubble-free liquid glass that meets the molding requirements.

4. Molding. Liquid glass is processed into products of the required shape, such as flat plates, various utensils, etc.

5. Heat treatment.

Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.

Precautions for glass handling:

1. In order to avoid unnecessary losses during transportation, we must pay attention to fixing and adding soft pads. It is generally recommended to transport it in an upright way. Vehicles should also take care to maintain steady, slow speeds.

2. If the other side of the glass installation is closed, pay attention to clean the surface before installation. It is advisable to use a special glass cleaner and to verify that there are no stains after it has dried thoroughly before installation, and it is recommended to use clean construction gloves for installation.

3. The installation of glass should be fixed with silicone sealant, and it should also be used with rubber sealing strips in the installation of windows.

4. After the construction is completed, it is necessary to pay attention to the anti-collision warning signs, which can generally be prompted by non-dry stickers and colored electrical tape.

The main component of glass is quartz sand, and its manufacturing process is a crystalline formed by cooling quartz sand with other chemical raw materials at high temperature (1300 degrees Celsius) after firing, which has hardness, anti-wear, high light transmittance and anti-corrosion characteristics, and its wide range of uses has a long history. Glass is now being used in a variety of applications, including watches, utensils, windows, doors, lighting, and high-tech technologies such as electronic components and space technology. The most common thing we come into contact with on a daily basis is flat glass, which is thick for doors and windows, and thin for watches and medical laboratory purposes, and is manufactured by using horizontal or traction methods (also known as float methods) and vertical traction methods in the glass slurry in the melting furnace.

The thickness of the flat glass is mainly determined by the speed of traction, the faster the traction speed, the thinner the thickness of the thickness of the plate glass. Although ordinary flat glass looks bright and transparent from the front, it is slightly cyan from the near edge of the side, because the color of the glass depends on the purity and iron content of quartz sand, the main raw material for making glass. Generally, the thin glass used in the watch industry is of higher quality, but the value is more expensive, mainly because the quartz sand used is a better raw material and has a very low iron content (generally less than 3 parts per 10,000).

How was glass born? Is it artificially made, or is it naturally formed?

Although humans have been making glass since before 400 B.C., it wasn't until the 20th century that there was a breakthrough in how glass was made. Although there are thousands of formulations, there are three main ingredients: formers, fluxes and stabilizers.

The function of the former is to form the structure of glass, the main ingredient is silica, and there are boron oxide, phosphorus oxide, etc. Mixing fluxes and formers lowers the melting point of the former for processing and formation. Common fluxes are barium oxide and sodium oxide.

The function of the stabilizer is to make the formation of stable glass, the common stabilizers are calcium oxide and alumina, and calcium oxide mostly comes from calcium carbonate heating. In addition to these three basic materials, modern special glass also has some raw materials that are used in small quantities as colorants or clarifiers, or make glass have special uses, such as gold and copper in colloidal state can be used as colorants, and antimony and arsenic can be used as clarifiers.

Most of modern glass is sodium and lime glass, which is used in the production of flat glass, various containers and light bulbs. The most used is silica, which is often mixed with limestone and sodium carbonate in different proportions.

In glass factories, the mixed raw materials are first poured into storage tanks. Then, the ingredients are heated again until they melt to a white heat. The glass is then subjected to appropriate treatment, such as pressing two heavy rollers into flakes and pouring them onto a steel table to make lithographic glass.

1. Glass is formed by melting sand, sodium carbonate and calcium carbonate together and cooling the brigade to a solid state.

2. Glass is a relatively transparent solid substance, which forms a continuous network structure when it is slowly melted in volcanic town, and the viscosity gradually increases and hardens without crystallization during the cooling process.

3. The main component of ordinary glass chemical oxide is silicon dioxide. Lack of mold.

1. Glass is formed by melting sand, sodium carbonate and calcium carbonate together and cooling to a solid state.

2. Glass is a relatively transparent solid skin substance, which forms a continuous network structure when the fibre melts the source limb, and the viscosity gradually increases and hardens without crystallization during the cooling process.

3. The main component of ordinary glass chemical oxide is silicon dioxide.

Glass has a variety of components, and ordinary glass is mainly composed of silicates, such as silicon dioxide, sodium silicate, calcium silicate, etc.
