包装电子仪器时,作为防震衬垫用的白色泡沫塑料板,大家往往把它当作废物扔掉,这很可惜。其实,它是做静电实验的极好材料,用它来做静电实验,有其明显的优点:首先,取材极易,不花分文,随手可得;其次,绝缘性能优良,受潮湿气候影响较小;第三,它质地轻软,很容易加工成型;第四,它不象石腊那样容易吸附灰尘,即便时间长久些,效果尚可。下面略举数例,以说明其几方面的应用,以供同志们参考。一、摩擦起电:几乎任何东西跟泡沫塑料摩擦,都可使它带电,我们取绸布、尼龙、涤纶、塑料薄膜、干净头发等,稍微跟它摩擦一下,即可使它
When packaging electronic equipment, as a shockproof cushion with white foam board, we often throw it away as a waste, which is a pity. In fact, it is an excellent material to do static electricity experiment. It is used to make static electricity experiment. It has obvious advantages: firstly, it is very easy to take materials without any paper; secondly, it has excellent insulation performance and is affected by humid climate Smaller; Third, it is light and soft texture, it is easy to process molding; Fourth, it is not as easy to adsorb dust like paraffin, even over time, the effect is acceptable. Here are a few examples to illustrate the application of several aspects for comrades reference. First, the friction electrification: Almost anything with the foam friction, can make it live, we take silk, nylon, polyester, plastic film, clean the hair, a little rub with it, you can make it
