This article will comprehensively introduce the characteristics and applications of silica gel raw materials from the aspects of definition, characteristics, advantages, benefits and application range.
1. Definition:
Silica gel (Silicone Rubber), as an artificial elastomer, is connected by the basic components of ternary siloxane SiO3. It is characterized by high molecular composition, high elastic strength, high temperature resistance, chemical corrosion resistance and Good repeat compression performance, etc.
2. Features:
Silicone has the following characteristics:
1. Excellent mechanical properties
Silicone exhibits excellent mechanical properties, with properties such as elasticity, wear resistance, crack resistance, good cut resistance, and low compression set.
2. Chemical stability
Silica gel has excellent chemical stability and can withstand the corrosion of various acids, alkalis, salts and chemicals. At the same time, silica gel can be used for a long time in various complex chemical environments.
3. Thermal stability
Silicone is a material with outstanding thermal stability, has a high operating temperature, can be used in high temperature environments, and its performance is basically not affected by temperature.
4. Not easy to age
Due to the protection of SiO2, the oxidation product of the silyl group, the silica gel is not easy to age.
5. Environmental protection
Compared with other synthetic polymer materials, silica gel is more environmentally friendly, because silica gel raw materials exist in nature and can be processed through biological cycles.
3. Advantages:
As a new type of polymer material, silica gel has many advantages, the most prominent of which are:
1. Strong chemical stability
Compared with other synthetic polymer materials, silica gel has superior chemical stability, and it has good corrosion resistance, UV resistance and good anti-aging performance.
2. Excellent physical properties
Silicone has good elasticity, toughness, wear resistance and excellent mechanical properties. At the same time, silica gel is very compressible, without compression permanent deformation, and will not become hard and brittle due to compression.
3. Wide range of application fields
Silicone materials are used in a wide range of applications. In addition to the common manufacture of small electrical devices such as watches, timers, computer keyboards, and game controllers, silica gel is also widely used in automotive parts, medical equipment, aerospace, construction, and home improvement.
4. High temperature resistance
Silicone can withstand higher operating temperatures, making it suitable for environments that require high temperature resistance.
5. Non-toxic and tasteless
Silica gel is a material composed of silane groups. It is non-toxic, tasteless, harmless to the human body, and meets the standards of human health and environmental protection.
4. Benefits:
As an emerging engineering material, silica gel has many advantages compared with traditional materials:
1. Silicone is a material with better machinability.
2. Silicone has better durability and longer service life after molding.
3. Silicone has better chemical corrosion resistance and weather resistance.
4. Silicone has good elasticity and will not be affected by age and environment.
5. The sealing performance of silica gel is better, and it is outstanding in resisting gas and liquid materials.
Five, the scope of application:
Silica gel has been widely used in people’s daily life, and it is constantly involved in new fields, such as:
1. Medical equipment
Silicone is widely used in the field of medical devices, such as medical silicone catheters, implants, infusion bags, artificial lungs, etc.
2. Automobile industry
As a superior material, it is widely used in the automotive industry, such as water tanks, cylinder head seals, suspensions, gaskets and shock absorbers, etc.
3. Construction and home improvement
Silicone is used in the fields of construction and home improvement, such as waterproof materials, adhesives, sealing materials and decorative materials.
4. Electronic industry
Silicone is very popular in the electronics industry, such as anti-static keyboards, mobile game handles, mobile phone cases and so on.
In a word, as a new type of polymer material, silica gel has replaced many traditional materials due to its many unique characteristics and wide range of applications. It will continue to be widely used in other fields in the future, bringing people a more convenient life.
