加速器辐照装置用于辐照生产医用输液塑料袋原膜材。所研制的350 keV电子高压加速器具有以下特点:在静电加速器中采用高压倍压电源代替输电带,此新型结构加速器可输出低能大功率电子束,且体积小、自屏蔽,适于在线辐照加工;一般高压倍压电源采用50 Hz供电,而在此装置中由14 kHz中频电源供电,高压电源体积小。加速器空载高压达370 kV,电子束350 keV/20 mA,扫描宽度70 cm,辐照剂量不均匀性好于7%。该加速器辐照装置已投入运行,并已生产出合格医用输液袋膜材投放市场,产品填补了国内医用输液袋膜材市场的空白。
Accelerator irradiation device for the production of medical infusion plastic bags original film. The developed 350 keV electron pressure accelerator has the following features: High-voltage double-voltage power supply in the electrostatic accelerator instead of the transmission band, the new structure accelerator can output low-power high-power electron beam, and small size, self-shielding, suitable for online irradiation processing ; General high voltage power supply 50Hz power supply, and in this device by 14kHz IF power supply, high voltage power supply small size. Accelerator no-load high-voltage 370 kV, electron beam 350 keV / 20 mA, scanning width of 70 cm, radiation dose uniformity better than 7%. The accelerator irradiation device has been put into operation, and has produced a qualified medical infusion bag membrane on the market, the product has filled the domestic medical infusion bag membrane market blank.
