    檢測瓦楞紙箱產(chǎn)品是否合格的標(biāo)準(zhǔn)?

    1、側(cè)壓強(qiáng)度測試:直接影響瓦楞紙箱的支撐強(qiáng)度,瓦楞紙箱主要受重力作用,側(cè)壓是評(píng)估混凝土強(qiáng)度的方法。
    1. Side pressure strength test: it directly affects the support strength of corrugated box. Corrugated box is mainly affected by gravity, and side pressure is the best method to evaluate concrete strength.
    2、斷裂強(qiáng)度測試:影響瓦楞紙箱的側(cè)面支撐強(qiáng)度 -
    2. Breaking strength test: influencing the side support strength of corrugated box-
    瓦楞紙箱保護(hù)產(chǎn)品,抗破損性是板材每單位面積可吸收和均勻增加的壓力值。此測試用于檢查紙箱在實(shí)際運(yùn)輸環(huán)境中承受靜態(tài)局部壓縮的能力。
    The corrugated box protects the product, and the damage resistance is the maximum pressure value that can be absorbed and evenly increased per unit area of the board. This test is used to check the ability of the carton to withstand static local compression in the actual transportation environment.
    3、粘接強(qiáng)度測試:粘接強(qiáng)度不足容易引起分層,大大降低了紙箱的抗壓強(qiáng)度。
    3. Bonding strength test: insufficient bonding strength is easy to cause delamination, which greatly reduces the compressive strength of the carton.
    4、厚度測試:如果在紙板加工過程中波紋高度損失太大,例如模切,即壓痕,開槽或印刷,則會(huì)大大減少。紙箱的抗壓強(qiáng)度,因此保持瓦楞紙板的厚度應(yīng)該是生產(chǎn)過程的關(guān)鍵部分。
    4. Thickness test: if the corrugated height loss in paperboard processing is too large, such as die cutting, that is, indentation, slotting or printing, it will be greatly reduced. Therefore, maintaining the thickness of corrugated board should be a key part of the production process.

    5、水分含量測試:指瓦楞紙或紙板的含水量。水分含量對(duì)紙箱的強(qiáng)度有很大影響。它是紙箱的三個(gè)重型缺陷檢測項(xiàng)目之一。如果水分含量太低,紙張?zhí)?,壓制時(shí)容易破碎,抗折性也差。如果瓦楞紙的含水量太大,單面機(jī)加工的瓦楞紙板容易卷曲,扭曲時(shí)可能會(huì)發(fā)生起泡和脫膠。
    5. Moisture content test: refers to the moisture content of corrugated paper or paperboard. The moisture content has a great influence on the strength of the carton. It is one of the three heavy defect detection items of carton. If the moisture content is too low, the paper is too brittle, easy to break when pressed, and the folding resistance is poor. If the moisture content of the corrugated paper is too large, the corrugated paperboard machined on one side is easy to curl, and blistering and degumming may occur when it is twisted.
    6、搖蓋折疊測試:是紙箱檢測中非常重要的指標(biāo),它可以顯示紙箱的質(zhì)量。
    6. Flap folding test: it is a very important index in carton detection, it can show the quality of carton.
