1. Bakelite boards in the field of electrical equipment
– Motors: In motors, bakelite boards can be used as insulating separators. When the motor is running, there are different potential parts inside, and the bakelite board can effectively isolate these parts, prevent current leakage, and ensure the normal operation of the motor. For example, in the three-phase asynchronous motor, between the stator and rotor, between the windings of different phases need good insulation material, bakelite board can be very good to meet this demand. And the mechanical strength of the bakelite board can withstand the vibration and mechanical stress generated during the operation of the motor, to avoid generator failure caused by damage to the insulation material.
– Transformers: Transformers require insulation between the core and the windings to prevent short circuits. Bakelite’s high insulation resistance and suitable dielectric constant make it an ideal choice. It is able to withstand the higher voltages generated during transformer operation, and at the same time can effectively reduce the capacitive coupling between the core and the windings, reducing energy loss. In oil-immersed transformers, bakelite boards can also resist the erosion of transformer oil and maintain good insulation properties.
– Switchgear: In all kinds of high-voltage and low-voltage switchgear, bakelite is used to make insulating parts for switches, such as insulating supports for isolation switches, insulating ties for circuit breakers, etc. These parts are required during switching operations. These parts need to withstand high voltage and mechanical force during switching operation. The insulating and mechanical properties of bakelite boards can ensure the safe and reliable operation of switching equipment, preventing arc generation and current leakage.
2. Bakelite in the field of electronic and electrical products
– Circuit boards: Bakelite is a commonly used substrate material in printed circuit boards (PCBs). It provides a mounting base for electronic components and ensures insulation between components. The flatness and stability of the bakelite board helps in the precise mounting and soldering of electronic components. For example, in simple electronic device circuit boards such as radios and small game consoles, bakelite can be used as an affordable and reliable substrate material. At the same time, its low thermal conductivity, to a certain extent, can prevent electronic components from overheating and play a role in thermal insulation.
– Electronic instrument shell: part of the shell of the electronic instrument is made of bakelite, mainly by using its insulating properties and a certain degree of mechanical strength. This can prevent users from electrocution, but also to protect the instrument’s internal electronic components from external physical damage. For example, some laboratory use of small electronic measuring instruments, the shell of the use of bakelite can ensure that the instrument is lightweight at the same time to provide adequate protection.
3. Bakelite in the field of electrical tools
– Tool handles: many electrical tools, such as screwdrivers, soldering irons, etc., the handle part is made of bakelite. This is because when using electrical tools, the operator’s hand will be in contact with the tool, and the insulating properties of the bakelite board can prevent electric shock accidents from occurring. Moreover, the hardness and texture of the bakelite board can provide a comfortable grip, and its surface can increase the friction after proper treatment, so that the tool is not easy to slip off during use.
4. Automotive industry field
– Automotive electronic system: In automotive electronic system, such as automotive engine control unit (ECU) circuit boards, automotive sensor insulation parts, etc., Bakelite can play its insulating and stabilizing properties. Automobile operating environment is complex, temperature changes, bakelite can adapt to this environment to a certain extent, to ensure the normal operation of automotive electronic systems. For example, in the engine compartment, bakelite panels can resist high temperature and engine vibration, providing reliable insulation protection for automotive electronic components.
5. Other areas
– Modeling: In the field of modeling, bakelite is widely used due to its easy processing characteristics. It can be cut into various shapes and sizes and is used to make structural components for architectural models, mechanical models, and so on. Its good mechanical strength and surface flatness make modeling more accurate and beautiful.
– Machining fixture: Bakelite board can be used to make fixtures in the machining process. Its insulating properties can prevent interference due to electrical conductivity in the machining process, while its hardness and machinability make it easy to produce fixture shapes that meet machining requirements.
