The test standard of paper angle protection is more and more strict, and the standard is more and more perfect. Paper corner guards can be customized according to different specifications and requirements of customers. It can play the role of strengthening the pallet in the transportation of goods, so as to avoid the damage to the corner of the edge in the process of handling, packing and transportation. It is made of cardboard laminated adhesive, so it can be recycled and recycled.

并且在出口集装箱中可以免熏蒸，节省成本，得到广泛运用。护角条又称边缘板、护角条、圆形纸护角，是上的包装产品之一，用来代替木料、五金、塑胶包装及其他笨重的包装方式。具有、份量轻、坚固、环保要求等特点。环绕型纸护角是纸护角的一种分类，是指制造成环形结构，可用于包裹在圆形产品两端，对产品端面提供保护。有什么测试方法和测试步骤来保护纸护角？对于这个问题，我想引用纸护角保护技术的所有方面的标准答案：

In addition, it can avoid fumigation in export containers, save cost and be widely used. Corner bead, also known as edge board, corner guard and round paper corner guard, is one of the most popular packaging products in the world, which is used to replace wood, hardware, plastic packaging and other bulky packaging methods. It has the characteristics of low price, light weight, firmness and environmental protection requirements. Surround type paper corner guard is a kind of classification of paper corner guard, which is made into a ring structure, which can be used to wrap the two ends of circular products to protect the end faces of products. What are the test methods and procedures to protect the paper corner guard? For this question, I would like to quote the standard answer of all aspects of paper corner protection technology:

我们从技术要求开始

We start with technical requirement

一是一般要求；

First, general requirements;

纸护角生产应本标准的要求，并应按照客户图纸或按照规定程序批准的密封样品制造。

Paper corner guards shall be manufactured in accordance with the requirements of this standard and shall be manufactured in accordance with customer drawings or sealed samples approved in accordance with specified procedures.

其次，它实际上是外观的要求。

Secondly, it is actually a requirement of appearance.

纸护角表面应平整，无撕裂、损伤、无毛边缘及严重污损。纸护角的边缘应整齐，与纸护角的纵向呈直角，倾角不得超过1.5度。不允许弯曲。

The surface of paper corner guard should be flat without tear, damage, hairy edge and serious stain. The edge of the paper corner guard shall be neat and at right angle to the longitudinal direction of the paper corner guard, and the inclination angle shall not exceed 1.5 degrees. Bending is not allowed.

第三，物质要求；

Third, material requirements;

纸护角的外层是全木桨或仿牛纸板，内层是砂纸。外面覆盖着牛纸板或仿牛纸板。

The outer layer of the corner guard is all wood oar or imitation cow board, and the inner layer is sandpaper. It's covered with cardboard or imitation cardboard.

纸护角保护的特殊试验方法，

Special test methods for paper corner protection,

纸护角的大纵向压力确定如下：

The maximum longitudinal pressure of the paper cover angle is determined as follows:

当样品的长度为300mm0.5mm时，样品的缺口必须是光滑的，直的，垂直于纵轴的边缘，样品上没有明显的缺陷，如变形、染色压痕、撕裂等。

When the length of the sample is 300 mm0.5 mm, the notch of the sample must be smooth, straight and perpendicular to the edge of the longitudinal axis. There are no obvious defects on the sample, such as deformation, dyeing indentation, tearing, etc.

测试仪器使用通用测试仪。试验机的测量值在每级满量程的10％90％之间，读数误差应在1％以内。将试验机的怠速调节72mm / min。将样品放置在两个压力板之间，并使样品轴与两个压力板表面的线重合，以确保样品的两个端面平行于压力板的表面。打开测试机器对样品施加压力直样品塌陷。

The General tester is used. The measured value of the testing machine is between 10% and 90% of the full scale of each stage, and the reading error should be within 1%. Adjust the idle speed of the testing machine to 72 mm / min. Place the sample between the two pressure plates, and make the sample axis coincide with the center line of the two pressure plate surfaces to ensure that the two end faces of the sample are parallel to the surface of the pressure plate. Turn on the test machine and apply pressure to the sample until it collapses.
