Characteristics and advantages of HV-80-JP supersonic flame spraying system

1, Solid cabinet design, fuel flow control area, pressure display area, electronic control area are modular layout, panel clear and easy to operate.
2. All imported valves, pressure switches, flow switches and sensors from Europe and America are of the same quality as those from Europe and America
3, The use of Japanese mitsubishi high-performance PLC control, after ignition automatically maintain oxygen and fuel, carrier gas flow output.
4. All the internal fuel, oxygen, carrier gas and cooling water connected on the equipment have the detection function to ensure that all preparation processes can be fully tested before ignition.
5. Monitor the running status of the equipment in real time. Once any part is found to be operating beyond the safe range, the whole system will stop sharply, send an alarm and provide fault information.
6. The equipment starts and stops automatically under the control of PLC, which reduces the possibility of operator's misoperation.
7. Communication interface is set up inside the equipment to control the operation of peripheral devices.
8. Signal shielding measures are adopted to protect peripheral devices from electromagnetic interference during high frequency arc ignition.
 

Requirements for pole roll:
High wear resistance: the roller is subjected to abrasive wear, adhesive wear, fretting wear during the work process, and the wear resistance is not enough, which not only affects the roller surface precision and the quality of the pole piece, but also reduces the production efficiency;
High density: compact structure, low porosity, high corrosion resistance, but also conducive to prevent pole piece coating and other foreign bodies into the roll surface;
High precision: the straightness, ellipticity and coaxiality of the roll are required to be high, otherwise the uneven thickness of the battery pole will be caused and the bonding force will be poor.
The company uses HVOF thermal spraying technology to prepare multi-component cermet composite coating on the surface of lithium high precision roller, which has the following characteristics:
1, coating hardness is high, microhardness up to 1100-1400Hv0.3, with high wear resistance;
2, the coating structure is uniform and dense, low porosity, (<0.6%), does not stick to the material, does not react with the battery electrode material;
3, coating bonding strength is high, using FM1000 adhesive test, can reach more than 90Mpa.
4, the follow-up by external high precision CNC grinding machine fine grinding, to ensure high precision roller straightness, ellipticity and coaxiality, to ensure less than 0.002mm
