        橡膠低溫脆性試驗(yàn)儀使用方法:


        ★接通電源,溫控儀和計(jì)時(shí)器顯示燈亮。


        ★向冷井中注入冷凍介質(zhì)(一般為工業(yè)乙醇),其注入量應(yīng)保證夾持器的下端到液面的距離為75±10mm。


        ★將試樣垂直夾在夾持器上。夾的不宜過(guò)緊或過(guò)松,以防止試樣變形或脫落。


        ★按下夾持器,開(kāi)始冷凍試樣,同時(shí)啟動(dòng)時(shí)序控制開(kāi)關(guān)(或按動(dòng)秒表)計(jì)時(shí)。試樣冷凍時(shí)間規(guī)定為3.0±0.5min。試樣冷凍期間,冷凍介質(zhì)溫度波動(dòng)不得超過(guò)±1℃。


        ★提起升降夾持器,使沖擊器在半秒鐘內(nèi)沖擊試樣。


        ★取下試樣,將試樣按沖擊方向彎曲成180°,仔細(xì)觀(guān)察有無(wú)破壞。


        ★試樣經(jīng)沖擊后(每個(gè)試樣只準(zhǔn)沖擊一次),如出現(xiàn)破壞時(shí),應(yīng)提高冷凍介質(zhì)的溫度,否則降低其溫度,繼續(xù)進(jìn)行試驗(yàn)。


        通過(guò)反復(fù)試驗(yàn),確定至少有兩個(gè)試樣不破壞的A低溫度和至少一個(gè)試樣破壞的A高溫度,如這兩個(gè)結(jié)果相差不大于1℃時(shí),即試驗(yàn)結(jié)束。


        How to use low temperature brittleness tester


        ★Turn on the power,the temperature controller and timer indicator lights up.


        ★Inject cold medium(usually industrial ethanol)into the cold well,and the injection volume should ensure that the distance from the lower end of the holder to the liquid surface is 75±10mm.


        ★Clamp the sample vertically on the holder.The clamp should not be too tight or too loose to prevent the sample from deforming or falling off.


        ★Press the gripper to start freezing the sample,and start the timing control switch(or press the stopwatch)to count.Specimen freezing time is specified as 3.0±0.5min.During the freezing of the sample,the temperature fluctuation of the freezing medium must not exceed±1°C.


        ★L(fēng)ift the lifting clamp to make the impactor impact the sample within half a second.


        ★Remove the sample,bend the sample to 180°in the direction of impact,and carefully observe whether there is damage.


        ★After the sample is impacted(each sample is allowed to be impacted only once),if damage occurs,the temperature of the refrigerating medium should be increased,otherwise the temperature should be lowered and the test continued.


        Through repeated tests,it is determined that there are at least two samples that do not break the A low temperature and at least one sample that do not break the A high temperature.If the difference between the two results is not greater than 1°C,the test is over.
