牛皮纸是一种常见的工业用纸材料, 由于其高强度和耐磨性, so it is widely used in the production of packing cases, bags, book covers, handbags and other fields.

检测性能
需要检测以下主要性能:

力量: kraft paper needs to have high strength to ensure that it is not easy to be damaged or broken in the process of making packing cases, bags and so on. 可以通过测量拉伸强度来进行强度检测, 抗弯强度, 纸张的抗压强度等指标.

耐磨性: kraft paper needs to have high wear resistance to ensure that it is not easy to damage or wear in the process of making book covers, handbags and so on. 通过测量纸张表面的摩擦系数可以进行耐磨性检测, 耐磨等指标.

Air permeability: kraft paper needs to have a certain air permeability, so that the quality of packaging goods and shelf life. The detection of air permeability can be carried out by measuring the permeability, porosity and permeability coefficient of the paper.

Water absorption: kraft paper needs to have a certain water absorption, so as to play a certain buffering role in the production process. The detection of water absorption can be carried out by measuring the moisture content, water absorption speed and water absorption of the paper.

环境保护: kraft paper needs to meet environmental protection standards, 不含有害物质, 对环境无污染. 通过测量挥发性有机化合物可以进行环保检测, 重金属, 纸张的氯离子和荧光增白剂.

牛皮纸需要测试性能及测试方法

适用范围: Kraft paper has a wide range of applications, involving the production of packing boxes, bags, book covers, handbags and other fields, which need to be tested and evaluated according to specific application requirements. 适用范围的检测可以通过测量纸张的适用环境来进行, the applicable product type and the applicable processing technology.

Packaging performance: The packaging performance of kraft paper is one of its important performance indicators, including packaging tightness, dimensional stability and stacking stability. The inspection of packaging performance can be carried out by measuring the thickness, toughness and surface flatness of the wrapping paper.

Appearance quality: because kraft paper is usually used for products with high appearance requirements, 它的外观质量也是一个非常重要的指标, which needs to be tested for appearance, 例如表面平整度, 表面光泽度, 表面光滑度, surface defect-free and other indicators.

These performance indicators are the key content of kraft paper detection, 不同的使用要求和标准也会影响纸张的检测标准和方法.
