탐지 방법
The test method and standard should be adopted according to different performance indexes. The following are some common methods of testing the performance of recycled pulp large-spindle paper:

Strength and tensile properties: Tensile and tensile properties can be evaluated using test methods such as tensile and tear tests. Tensile test generally adopts multifunctional testing machine, with longitudinal and transverse as the main testing directions. The tearing test evaluates the strength of the paper by measuring its tearing force under certain conditions.

Surface smoothness: The surface smoothness can be assessed using a surface smoothness tester, which evaluates the surface smoothness of a paper by measuring its roughness index.

Water absorption performance: The water absorption performance can be assessed using an water absorption tester, which measures the water absorption capacity of the paper to assess its water absorption performance.

Rupture resistance: It can be assessed by using a rupture tester, which measures the breaking force of paper under certain conditions.

Glossiness: Glossiness can be assessed using a glossiness tester, which measures the intensity of light reflected from the paper to assess its glossiness.

환경 보호: Its environmental protection performance can be evaluated by detecting heavy metals and harmful substances, such as X-ray fluorescence spectrometer, inductively coupled plasma mass spectrometer and other instruments to detect the samples.

Bond properties: Bond properties can be evaluated using a peel strength tester, which measures the bond strength between the paper and the bond material.

Biodegradability: Biodegradability can be assessed using methods such as soil burial tests, which measure the rate of degradation and changes in mass of paper by burying it in the soil.

Paper thickness: The thickness of the paper can be measured using instruments such as feel thickness meter and electronic thickness meter for evaluation.

Paper moisture content: Paper moisture content can be measured using a paper moisture content tester for evaluation purposes.
