Gaoya dianqi, 1972 电泳涂漆已经在我国广泛采用。它具有涂膜均匀、附着力强、成本低、安全等大家公认的优点。它的缺点是要用直流电,需要一套蓄电池或硅整流设备。伟大领袖毛主席教导我们说:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。”遵照毛主席这一教导,我们对电泳涂漆的电源作了改进,采用交流电泳涂漆。经过几十次的试验和试生产的检验证明:用交流电电泳涂漆是可行的。它的优点是:不需要从主交流电源整流,不必经变压器变压 ...

A rapid intermittent charge method with variable current for VRLA battery [PDF]
, 1999 VrlA蓄电池充电分为两段：先控电流，后控电压。对于完全放电态电池（6-fM-4.0），采用恒电流充电使电池达到85%荷电态，最佳充电电流是0.1C，充电时间需要9H。采用变电流间歇充电，充电时间不足3H，可达到92%以上荷电态。最后采用相同的控电压充电使电池恢复至完全充电态，前者需要9H，后者只需6H。本文已给出变电流间歇充电器的原理电路。There are two charging stages: the first one is a charging current control, and ...

The Interrupt Charge Method with Variable Current For VRLA Battery [PDF]
, 1998 进一步给出已由我们建立的变电流间歇充电方法研究结果。通过试验说明了充电时采用变电流和间歇的必要性。放电态电池恢复至完全充电态,标准充电方法的充电时间需要1080MIn(电流段583MIn,电压段497MIn),而这方法只需要540MIn(电流段138MIn,电压段402MIn)。已提出适合于这方法的充电器电路。讨论了充电接受能力和快速部分充电的研究思路。The Further research results on the interrupt charge method with variable ...

Infl uence of composite material of carbon black and graphite on the performance of negative electrode of lead-acid battery [PDF]
, 2014 本文考察了加入不同含量混合炭材料(如炭黑与石墨)的铅酸电池负极的电化学性能。通过循环伏安测试,研究了炭材料对负极氧化还原性能与析氢电位的影响。通过扫描电镜测试,观察了负极微观形貌的变化。充放电测试结果表明,铅酸电池负极活性物质中炭材料的含量对其倍率放电性能具有重要影响。适量添加炭黑与石墨的混合材料,可以提高负极高倍率条件下的放电容量。当添加3%炭黑和2%石墨混合炭材料时,对负极充电时的析氢电位影响较小,10 C放电条件下得到较高容量。This paper observed and studied the
