Product advantages:
1. The materials are authentic and reliable. The furnace body is made of 304 stainless steel, which is built in strict accordance with the pressure vessel standard and has good corrosion resistance and airtight performance. The insulation materials are made of high-purity graphite felt, which is durable. All electrical components are imported or domestic top brands with reliable operation.
2.Vacuum carbonization of high thermal conductivity film is the key equipment for the production of the high-performance thermal film. The PI film carbonized by this equipment has excellent resistance structure and density. Continuous vacuum carbonization and sintering process can be realized; Being equipped with a decoking system to strengthen the decoking effect, the working condition in the furnace is more stable, and the product quality is easy to be controlled; The service life of carbon felt and heating materials is prolonged.
3. Using resistive heating, the graphite tube heating element has a long life, good heating effect, and easy maintenance capability. Uniform heating, reliable heat insulation and temperature measurement system, advanced furnace chamber design concept, reasonable heating structure, and high-quality materials all ensure the uniformity of furnace temperature under vacuum conditions. Using domestic and international top brands temperature measurement components to ensure temperature measurement accuracy. Advanced temperature control system, imported digital display intelligent temperature control meter can communicate with PLC; With complete automatic temperature measurement and control process with high precision, the system can heat up according to a given heating curve and can store 4pieces of 40 different process heating curves with a single room, horizontal structure, compact and reasonable equipment layout, small footprint.
4. Advanced automatic control, comprehensive water, electricity, and gas automatic control and protection system, PLC, which can realize safety interlock with sound and light alarm for sensor breakage, over high water pressure, furnace body overpressure, over high water flow, over high water temperature, etc.. Environmental protection, energy saving, no purification essence vacuum exhaust gas, effectively protecting the normal operation of the vacuum pump and excellent the decoking effect.
5. The high-temperature section of the furnace body adopts natural cooling; the low-temperature section cooling can be overcharged with positive pressure inert gas to speed up the cooling rate. The furnace body explosion-proof valve is safe and reliable.
