磁片——无线充电系列篇
magnetic sheet——wireless charging series chapter
无线充电作为一种时尚便捷的充电方式,越来越受到广大消费者的青睐,在手机、游戏机等消费类电子产品领域正以迅猛的势头发展。但无线充电器却存在充电效率低、充电时发热量大等缺陷。为了提高充电效率、确保使用安全,目前的主流解决方案是在无线充电器发射端和接收端线圈背面贴加隔磁片。
深圳鹏汇功能材料有限公司为无线充电器装置专门研制开发出wlf15和wls30系列高性能磁片,以满足无线充电时不同电流、不同频率、不同厚度条件下的需求。
as a kind of fashionable and convenient charging way, wireless charging more and more get the favour of the consumers, and is developing rapidly in the field of consumptive electronic products ,such as mobile phones and playstations. but wireless charging has defects of low charging efficiency and high heating value. the current mainstream solution to improve these problems is pas ting a kind of material named magnetic-isolation sheet to the back of both the transmitting coil and the receiving coil.
shenzhen ph functional materials co., ltd have specially developed wlf15 and wls30 series of magnetic sheets with high-performance for wireless charger. so that these materials can meet the wireless charging under the conditions of different currents, different frequencies and different thickness.

为了在不同情况下达到不同的屏蔽效果,我们可以选择不同厚度的材料以及不同性能的磁性片材。对磁性片的要求有:
ø  磁性能优异,磁导率高;
ø  磁性片在交流磁场中的磁损耗较小;
ø  磁性片有较好的柔韧性,在贴合时不致断裂,否则会引起漏磁。
in order to receive the different shielding effects, we can choose the magnetic sheet materials that they have different thickness and properties. the magnetic sheets are:
ø  excellent magnetic properties, higher permeability;
ø  lower magnetic loss in the ac magnetic field;
ø  good flexibility, and don’t be laminated when they are fixed, otherwise they will cause the magnetic flux leakage.
