Application of organic silica gel adhesive


Nowadays, silicone materials have become the materials frequently used in all walks of life. Silicone is used in the manufacture of mobile phones, Internet, wireless computers and smart cards, and silicone adhesive is the material produced in this case. Next, let's learn about the application of silicone adhesive from new Jiayi.


I. protection equipment


Silicone can provide perfect sealing function, protect extremely sensitive electronic components and components from external pollution or movement. This is of great significance to ensure the long-term stability and performance of many electronic products. In addition, the silicone material will not corrode or self ignite, meeting the most stringent safety and purity requirements in the production and manufacturing of electronic products.


The isolation of silicone helps to protect the circuits of TV, computer and aircraft video display from heat, dirt and dust. At the same time, silicone is very suitable for high-voltage applications, which can insulate the ground and underground cables and power supply lines.


II. Enhanced performance


With the electronic equipment becoming thinner, smaller and faster, the excellent physical properties of organosilicon make it able to display its skills in new application fields: high temperature and low temperature stability, excellent insulation, strength, elasticity and toughness, moisture resistance, chemical stability, UV resistance and other environmental protection characteristics, which can bond and protect a variety of materials.


III. typical application


Silicone sealant, adhesive and coating can be used for circuits, connectors, capacitors, coils, transistors and picture tubes of most consumer and commercial electronic equipment


1, automobile


Organosilicon can isolate extremely sensitive automotive electronic components. Silicone helps to protect the performance of electronic components at extreme temperatures from humidity, salt corrosion and other corrosive environments. Silicone helps to ensure reliable operation of electronic components in airbags, body components, brake systems, ignition, fuel and air systems and drives.


2. Aviation and aerospace


Silicone can withstand the pressure and temperature limits necessary for aerospace. Silicone adhesive, sealant and potting agent can ensure that electronic components and systems work well. For example, these materials can protect electronic printed circuit boards from humidity and pollution.


3. Communication


Organosilicon can seal, glue and encapsulate mechanical and electronic components in household and office equipment, including power transistor rectifier thermal control switch. The auxiliary keyboard, keyboard and duplicator cylinder are all made of silicone -- the hard coating of computer, fax machine, telephone and home entertainment equipment shell is made of silicone material.


4. Cleaning and decontamination fluid


Silicone emulsion is a good cleaning agent, which can remove residual cleaning materials from space navigation system, electronic equipment and medical device components.


5. Household appliances


Automatic coffee machine, digital transponder, microwave oven, steam iron, stereo system, TV, washing machine, vacuum cleaner almost all electronic components of household appliances are protected by silicone materials, so their service life is extended. With silicone, household appliances are safer, more reliable and require less maintenance. Silicone also promoted the birth of new "smart home appliances" - smaller electronic systems with more advanced functions.


6. Microelectronics and microprocessors


High purity silicon (made of silicone) is very important for sensitive circuits. With the development of technology, the processing capacity is increased and the volume is reduced. Organosilicon can meet the changing needs of microelectronic devices, components, components and systems in the IC packaging industry.


7. Circuit board and electronic module


Silicone is very important for the assembly and protection of the finished circuit board or electronic module. Various silicone materials, coating, sealant and gel can enhance the insulation and chemical resistance of the material, protect them continuously, resist moisture, humidity, vibration, overheating, corrosion and radiation. Sealants, adhesives, and primers can be easily manufactured with a variety of common materials, including ceramics, active metals, and filler plastics. This is conducive to aseptic and rapid mass production of electronic system.


8. Semiconductor


Organosilicon can encapsulate and protect semiconductors, which are essential components of almost all electronic devices. High voltage / power applications such as industrial motors, locomotives and power supplies requiring high-voltage switches; high frequency communications such as cell phone base stations, satellites and radars; high temperature applications such as aircraft engines, oil drilling and automotive electronic equipment (including sensors to control fuel efficiency and emissions); the operation of these equipment requires semiconductors.


9. Power and power supply


Power transmission depends on non polluting insulation to avoid costly and dangerous interruption of the power supply system due to exposure to water, salt, sand or industrial pollutants. Silicone can provide high voltage insulation coating to protect wires, power and communication cables. The silicone insulation device can ensure the safe and continuous transmission of high-energy power by underground and above ground cables. The inherent durability of silicone can prolong the life of the material, reduce the cost of maintenance and replacement.
