有些紙箱企業(yè)在檢測邊壓強度時，沒有選擇導(dǎo)塊支撐樣，這就簡單地形成了樣壓過程中的傾斜現(xiàn)象，數(shù)據(jù)偏低。正確的方法是將樣品在緊迫的中心板測試儀器,支持導(dǎo)塊的樣品,樣品的表面是垂直于壓盤,移動導(dǎo)塊壓力接近50 n直到樣本崩潰,并記錄樣例可以承受的大壓力。
Some carton enterprises do not select the guide block support sample when testing the edge pressure strength, which simply forms the tilt phenomenon in the sample pressure process, and the data is low. The correct method is to place the sample on the urgent central plate test instrument to support the sample of the guide block. The surface of the sample is perpendicular to the pressure plate, and the pressure of moving the guide block is close to 50 N until the sample collapses, and record the maximum pressure that the sample can bear.
對具有斷裂強度的試樣分別從正、負(fù)、負(fù)、負(fù)、負(fù)四個角度進行檢測。然而，一些企業(yè)在測試時沒有考慮樣品的角度。實際上，在試驗實踐中，正橫、負(fù)橫、正橫、負(fù)橫四個不同角度的試驗結(jié)果有時相差很大。
The samples with fracture strength were tested from four angles: positive, negative, negative, negative. However, some enterprises did not consider the angle of samples when testing. In fact, in the experiment practice, the test results of positive horizontal, negative horizontal, positive horizontal and negative horizontal are sometimes quite different.
在進行斷裂強度試驗時，應(yīng)拋棄二次爆炸聲數(shù)據(jù)或試樣有明顯滑移時的數(shù)據(jù)，分別測量試樣的正、負(fù)向。在正常情況下，應(yīng)檢查更多的異常檢驗數(shù)據(jù)，以驗證檢驗效果是否屬于偶然現(xiàn)象，避免形成錯誤判斷。
When carrying out the fracture strength test, the data of the secondary explosion sound or the data of the specimen with obvious slip shall be discarded, and the positive and negative directions of the specimen shall be measured respectively. Under normal circumstances, more abnormal inspection data should be checked to verify whether the inspection effect is accidental and avoid wrong judgment.
紙箱抗壓強度測試時，不封箱檢查，測試數(shù)據(jù)較低。正確的方法是先將樣品箱三維封口，用封口膠帶封口，然后將樣品箱放在反壓試驗機壓板中間，以標(biāo)準(zhǔn)速度加壓，直紙箱壓碎。
When testing the compressive strength of cartons, they are not sealed for inspection, and the test data is low. The correct method is to seal the sample box in three dimensions, seal it with sealing tape, and then place the sample box in the middle of the pressing plate of the back pressure tester, pressurize it at the standard speed until the carton is crushed.
一般客戶在收到游標(biāo)卡尺或直接用卷尺直接測定紙板的垂直邊緣，來測定紙板的厚度。因為紙板生產(chǎn)線在分切時，薄刀分切有一定的壓力，紙板分切邊緣一般會塌陷，所以時間測量值會很低。事實上，在厚度測量中，守時性是在一定的壓力下測量的，多點接觸測量應(yīng)該取平均值。
The thickness of the board is measured by the customer when receiving the vernier caliper or directly measuring the vertical edge of the board with a tape. Because there is a certain pressure in the slitting of the cardboard production line, the edge of the cardboard slitting generally collapses, so the time measurement value will be very low. In fact, in the thickness measurement, the punctuality is measured under a certain pressure, and the multi-point contact measurement should take the average value.
