Main Features Of High Frequency Hot Press
First of all, the medium used in high-frequency hot press is usually insulator, such as wood, plastic, rubber, glass fiber, water and glue, etc. High frequency hot press heating is to put the medium in high frequency electric field. Under the action of electric field, the molecules are arranged along the direction of electric field. High frequency electric field changes its direction continuously with very fast speed. The molecules of dielectric materials rotate or vibrate at high speed in the original position, and the friction and collision between particles generate heat, so as to achieve the purpose of heating.
The high frequency hot press has strong output power and reliable performance. The coaxial oscillator and tuner with low loss make the high frequency hot press have strong output power, which shortens the hot pressing time and improves the output power.
For high-frequency hot press, we need to understand the main components of high-frequency hot press description and cleaning, and have a deep understanding and exploration of high-frequency hot press. Main features:
1. High frequency hot press heating speed, high efficiency. When the thickness of the workpiece is less than 20 mm, the conduction heating time is usually 1 min / mm. When the thickness is greater than this value, the heating time will be greatly extended, and the influence of the thickness of the workpiece on the high frequency heating will be much smaller. Under the same workload, high frequency heating only takes 2 hours to complete, while conduction heating takes 5-6 days.
2. Uniform heating: high frequency hot press generates heat inside the object. Heating the processed wood to the same temperature inside and outside the whole wood can effectively improve the curing strength of the adhesive and improve the product quality. Wood splicing can make the adhesive joints in the same electric field generate heat, but the wood itself will not be overheated.
3. Environmental protection, no boiler, no dust, safety and health.
Note during operation:
1. The high-frequency equipment must be operated by two persons through the above data, and the person in charge of the operation technology must be designated, wearing insulating shoes, gloves and other specified protective equipment.
2. The operator must be familiar with the operation procedure of the high frequency equipment, check whether the cooling system of the equipment is normal before starting, and then turn it on, and strictly follow the operation procedure.
3. Before operation, all doors shall be closed and electrical interlock device shall be provided on the door to ensure that power cannot be supplied before the door is closed. Do not move to the back of the machine or open the door after switching off the high pressure.
4. The high-frequency equipment should be kept clean and dust-free during operation. In case of any abnormality in the work, the high-voltage power supply should be cut off first, and then the equipment should be checked to eliminate relevant faults. When the high-frequency equipment has problems, it must be repaired by professional personnel. After opening the equipment, first use the electric rod to discharge the power grid, capacitors and other live parts, and then start the maintenance. Pay attention to strictly prohibit live maintenance.
High frequency hot press can process any special purpose of soft and hard rubber, leather or cloth. It can also be used in furniture, wood, touch screen, printer and other fields.
