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(duì)具有斷裂強(qiáng)度的試樣分別從正、負(fù)、負(fù)、負(fù)、負(fù)四個(gè)角度進(jìn)行檢測(cè)。然而，一些企業(yè)在測(cè)試時(shí)沒(méi)有考慮樣品的角度。實(shí)際上，在試驗(yàn)實(shí)踐中，正橫、負(fù)橫、正橫、負(fù)橫四個(gè)不同角度的試驗(yàn)結(jié)果有時(shí)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(jìn)行斷裂強(qiáng)度試驗(yàn)時(shí)，應(yīng)拋棄二次爆炸聲數(shù)據(jù)或試樣有明顯滑移時(shí)的數(shù)據(jù)，分別測(cè)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(yàn)數(shù)據(jù)，以驗(yàn)證檢驗(yàn)效果是否屬于偶然現(xiàn)象，避免形成錯(cuò)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(qiáng)度測(cè)試時(shí)，不封箱檢查，測(cè)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(yàn)機(jī)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(cè)定紙板的垂直邊緣，來(lái)測(cè)定紙板的厚度。因?yàn)榧埌迳a(chǎn)線在分切時(shí)，薄刀分切有一定的壓力，紙板分切邊緣一般會(huì)塌陷，所以時(shí)間測(cè)量值會(huì)很低。事實(shí)上，在厚度測(cè)量中，守時(shí)性是在一定的壓力下測(cè)量的，多點(diǎn)接觸測(cè)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.
