    濟南(nan)三泉中石實驗儀器有限公司(si)研發生產的RSY-03來檢(jian)測(ce)鋰電池(chi)隔膜的熱(re)收縮率(lv)，本檢(jian)測(ce)儀器采用微(wei)電腦控制(zhi)，PID溫(wen)度控制(zhi)，液體加熱(re)介質，溫(wen)度控制(zhi)，受熱(re)均勻(yun)，用于電池(chi)隔膜、熱(re)縮管、背板等(deng)材(cai)料(liao)在(zai)多種(zhong)溫(wen)度下進行(xing)熱(re)收縮性(xing)(xing)能(neng)及(ji)尺寸(cun)穩定(ding)性(xing)(xing)的測(ce)試。

    經過多次試驗可知，鋰電池隔(ge)膜熱縮(suo)試驗儀可以(yi)測量鋰電池隔(ge)膜受熱時(shi)的(de)收縮(suo)力和收縮(suo)率，全面反(fan)映(ying)材料的(de)熱收縮(suo)性能，為(wei)電池隔(ge)膜質量控制(zhi)提供可靠的(de)參(can)考依據。
