Beating, according to the lower right direction key digital head position, press
Key head up as the Numbers increase, press down the head for figures
Reduced. Temperature setting, press "SET" key to return
Red digital instrument for indoor actual temperature
- 儀表紅色數字為室內實際溫度。Red digital instrument for indoor actual temperature
四、試驗步驟：Test steps
- 試驗的矩形試件尺寸（150±1）mm×（25
±1）mm,試件從試樣寬度方向上均勻的裁取,長
邊在卷材的縱向，試件裁取時應距邊緣不少于
150mm,試件應從卷材的一邊開始做連續的記號，
同時標記卷材的上表面和下表面。
Test of rectangular specimen size (150 + 1) mm x (25 + 1) mm, uniform cropping specimens from the sample width, long edge in vertical coil, specimen cropping should be away from the edge of not less than 150 mm, specimen from one side of the coil began to make a continuous mark, mark coil on the surface and under surface at the same time
去除表面的任何保護膜，適宜的方法是常溫下
用膠帶粘在上面，冷卻到接近假設的冷彎溫度，然
后從試件上撕去膠帶，另一方法是用壓縮空氣吹[壓
力約0。5Mpa(5bar),噴嘴直徑約0。5mm]，假若上
面的方法不能除去保護膜，用火焰烤，用zui少的時
間破壞膜而不損傷試件。
Remove any protective film on the surface, the appropriate method is room temperature use sticky tape on it, cold bending temperature cooled to near hypothesis, and then removing the tape from the specimen, another method is to use compressed air to blow [pressure about 0. 5 mpa (5 bar), nozzle diameter 0. 5 mm], if the above methods can't remove the protective film, roasted with fire, destruction of membrane with the least amount of time without damage to the specimen.
試件試驗前應在（23±2）℃平板上放置至少
4h,并且相互之間不能接觸，也不能粘在板上。可
以用硅紙墊，表面的松散顆粒用手輕輕敲打除去。
Specimens should be in before the test (23 + 2) ℃ tablet placed at least 4 h, and can't contact with each other, also can't stick on the board. Can use silicon paper pad, loose particles on the surface of the knock gently to remove by hand
2． 在開始試驗前，兩圓筒和彎曲軸之間的距離
應按試件厚度調節，根據所作試樣厚度選擇相適應
的彎曲軸，將彎曲軸放在兩個圓筒之間的位置上。
把溫控儀的設定溫度調至高于室內實際溫度，開動
控制器上升或下降開關，使彎曲軸和圓筒平行排列，
Ф30mm 和 Ф 50mm 彎曲軸可高出兩圓筒10—
20mm。松開圓筒兩面的羅絲，在彎曲軸和圓筒之間
放入和試件相對應的定位板，然后上緊圓筒兩面的
羅絲，取下定位板。距離調好后，將試驗裝置放入
試槽內。并且圓筒的上端在冷凍液下面約10mm,
開動下降開關，使彎曲軸下降至停止位置。
Before starting test, the distance between the two cylinders and bent crankshaft should be according to the specimen thickness adjustment, according to the specimen thickness choice appropriate to the bending of the crankshaft, will turn the crankshaft in position between the two cylinders. The temperature controller set temperature to higher than indoor actual temperature, up or down to start the controller switch, the bending of the crankshaft and cylinder parallel arrangement, Ф 30 mm and Ф 50 mm bent crankshaft can be higher than that of two cylinder 10-20 mm. Loosen the both sides of the cylinder, rose between the bending of the crankshaft and cylinder into and specimens corresponding to the positioning plate, and then to tighten the cylinder sides rose, remove the positioning plate. Distance set, after the test unit into the slot. And the top of the cylinder in the coolant below about 10 mm, start the drop switch, resulting in a bent crankshaft to the stop position
3. 兩組各5個使件，一組是上表面試驗，另
一組下表試驗，將試件放置在圓筒下面的支撐裝
置上，并且在彎曲軸在的上端，保證冷凍液*
浸沒試件。然后把試驗裝置放入試驗箱內，設定好
儀表的溫度。5 make pieces of each of the two groups, one group is on the test surface, another group in the table below test, place the specimen in the cylinder below the support device, and in turn the crankshaft in the upper, to ensure that the frozen liquid immersion specimen compley. Then put the test unit into the test box, set the temperature of the instrument
4. 控制器溫控儀的溫度根據試驗要求可設定在
－20℃～-25℃，首先接通電源后電源指示燈亮，
然后打開“開關”旋鈕待儀表十秒鐘后顯示正常溫
度后方可打開“工作”旋鈕，這時機器開始制冷，
制冷指示燈亮。當儀表溫度到達設定的溫度時，恒
溫指示燈亮計時器開始計時，計時器完畢后，電機
自動上升，彎曲軸以（360±40）mm/min速度頂著
試件向上移動，試件同時繞軸彎曲180度，這時實
驗已經做完。如在作實驗時，把面板上控制電機開
關的“下降”降到zui低，放上試件后按一下“復位”
開關，這時機器又開始重新實驗了，待實驗結束后
方可關閉電源開關。
Controller according to the test the temperature of the temperature controller can set in - 20 ℃ ~ 25 ℃, first switched on after the power indicator, open the "switch" knob to the instrument after ten seconds later showed normal temperature rear can open the "work" knob, then the machine start cooling, refrigeration indicator. When the instrument temperature reaches the set temperature, constant temperature indicator timing starts the timer, timer, motor automatically rise, bending the crankshaft (360 + 40) mm/min speed move upward against the specimen, specimen bending axis 180 degrees at the same time, the experiment has been done. As in the experiment, the panel switch control motor to minimize the "drop", put on the specimen after click the "reset" switch, the machine to the experiment again, and after the experiment can be shut off the power switch.
