Tinted glass: effectively absorb solar radiation heat and achieve the effect of heat shielding and energy saving; Absorbs more visible light and softens the light that passes through; Strong absorption of ultraviolet rays to prevent the impact of ultraviolet rays on the room; The color is bright and durable, which increases the appearance of the building.

2. Coated glass: the thermal insulation effect is good, and it is easy to produce light pollution to the external environment.

3. Insulating glass: good optical performance, good thermal insulation performance, anti-condensation, and good sound insulation performance.

Features of soda-lime glass:

The main function of calcium oxide in glass is to increase the chemical stability and mechanical strength of glass, but when the content is high, it can increase the crystallization tendency of glass and make the glass brittle. Generally, the content of calcium oxide in glass does not exceed. It is usually introduced through raw materials such as calcite, limestone, chalk, precipitated calcium carbonate, etc.

Uses of soda-lime glass:

Soda glass usually contains more impurities, such as iron impurities, so ordinary glass often has a light green color. Soda glass has a low cost, so it has a wide range of applications in architectural and daily glass products. The door and window glass we usually use also mostly belong to sodium glass or deep processing products of sodium glass.

The advantage is that it is relatively safe.

The disadvantages are:Soda-lime glassThe thermal shock resistance is relatively poor, and there is a possibility of breaking when boiling water is poured.

When using glasses, we need to pay attention to the fact that the glass is relatively hard, and it will be relatively brittle, the strength is not very high, and the thermal conductivity will be poor, so when using soda-lime glasses, pour a little hot water first, then shake the bottle, and then pour hot water.

On the premise of understanding soda-lime glass, let's first understand what is Nagai glass, soda-lime glass is mainly one of the silicate glasses, mainly made of silicon dioxide.

Calcium oxide and sodium oxide.

and so on. Such as commonly used flat glass, bottles, cans, light bulbs, etc. Sodium oxide increases the coefficient of thermal expansion of the glass car.

Reduce the thermal stability, chemical stability and mechanical strength of the glass, so the proportion can not be introduced too much, generally not more than 18%.

Soda ash is generally used in the production of glass.

way to introduce sodium oxide. The main function of calcium oxide in glass is to increase the chemical stability and mechanical strength of glass, but when the content is high, it can increase the crystallization tendency of glass and make glass brittle. Generally, the content of calcium oxide in glass does not exceed.

Usually by calcite.

Raw materials such as limestone, chalk, and precipitated calcium carbonate are introduced.

Soda-lime glass is an inorganic amorphous material, mainly composed of elements such as sodium, calcium, silicon and oxygen.

This glass usually has a transparent or translucent appearance and has excellent physical, chemical and optical properties, so it is widely used in many fields, such as electronics, laser technology, biomedicine, energy science and so on. Soda-lime glass can also adjust its properties by changing its composition and preparation method to meet the needs of different fields.

Soda-lime glass is widely used in many fields due to its excellent physical, chemical and optical properties, and here are some common applications:

1. Electronic devices: soda-lime glass can be made into low-temperature ceramics, which are used to manufacture piezoelectric ceramic piezoelectric sensors, divination filters and resonators and other electronic components.

2. Laser technology: soda-lime glass is widely used in laser technology, such as ND:YAG laser bar, which is soda-lime glass prepared by ion exchange.

3. Biomedical: Soda-lime glass is widely used in the biomedical field, such as biodegradable soda-lime glass can be used as bone repair materials.

4. Energy technology: Soda-lime glass can also be used for the surface coating of solar panels to improve its reflectivity and transparency.

5. Optical field: soda-lime glass has good transparency and optical properties, so it also has applications in the optical field, such as for the manufacture of optical lenses, optical fibers and optical filters.

Soda-lime glass has important application value in many fields, and with the continuous progress of technology, its application prospects will be broader.

Advantages and disadvantages of soda-lime glass

Advantages: 1. Good optical properties: Soda-lime glass has good transparency and optical properties, which can be used to manufacture high-quality optical components.

2. Strong chemical stability: soda-lime glass has good corrosion resistance to a variety of chemicals, and is not easy to be polluted and oxidized.

3. Good processability: Soda-lime glass can be processed and molded by a variety of technologies, such as ion exchange, electron beam melting, etc.

4. Excellent physical properties: soda-lime glass has high strength and hardness, and can be applied to some fields that require high strength and wear resistance.

Disadvantages: 1. Greater brittleness: Although soda-lime glass has high hardness and strength, because it is an amorphous material, it is brittle and easy to break.

2. Large coefficient of thermal expansion: the number of thermal expansion of soda-lime glass is relatively large, which may lead to deformation or cracking when the temperature changes.

3. Difficult to prepare: Compared with other materials, the preparation of soda-lime glass is technically difficult, and complex processes such as low-speed cooling under high temperature conditions are required.

4. Poor biodegradability: soda-lime glass takes a long time to decompose in the organism, so the biodegradability is poor.

To sum up, soda-lime glass has many advantages, such as good optical properties, chemical stability, etc., but also has some disadvantages, such as greater brittleness, large coefficient of thermal expansion, etc. These features need to be weighed and selected according to the actual application situation.

Because soda-lime glass has poor thermal shock resistance and is easy to break, it is not recommended. Soda-lime glass belongs to silicate glass, which is mainly composed of silicon dioxide.

Calcium oxide and sodium oxide.

and other components, common ones include flat glass, bottles, cans, light bulbs, etc.

Why is soda-lime glass not recommended?

Soda-lime glass is not recommended not because it contains toxic substances Zaohui, but because of its own material, which is extremely fragile.

Although calcium oxide can increase the chemical stability and local mechanical strength of the glass, it is better not to add too much, and the content of calcium oxide in the glass should not be exceeded, otherwise the glass will be brittle.

Calcium oxide is usually passed through calcite.

Limestone, chalk, precipitated calcium carbonate.

and other raw materials are introduced into the glass.

Summary. The main differences are in composition, performance, appearance, density, and resistance to cold and heat.

The composition is different: the composition of soda-lime glass is mainly silicon, sodium, and calcium; Borosilicate glass is mainly composed of silicon and boron.

Different performance: Generally, many properties of soda-lime glass are not as good as borosilicate glass, borosilicate frit is short, it is difficult to form, and there will be some molding defects on the product more or less, such as cold lines, material marks, scissor marks, etc.

The appearance is different: if it is fed and pressed, there will be no cold lines, and if it is a circle, it is not necessarily if it is other forming methods.

Different densities: Generally, the density of borosilicate glass is smaller than that of soda-lime glass, which can be compared by buoyancy density.

The difference between soda-lime glass and tempered glass.
