The performance test of yarn paper usually includes the following aspects:

Detection of base weight: The base weight per square meter is calculated by weighing the weight of a sample of yarn paper of a certain size. Use a precision electronic scale or balance for measurement.

Detection of thickness and uniformity: by measuring the thickness of the yarn paper using manual or automatic thickness gauges, and by laser measurement or machine measurement methods to detect uniformity. Manual thickness gauges usually use hand-held thickness measuring instruments, automatic thickness gauges usually use laser triangulation to measure thickness, and the method of detecting uniformity can be carried out using machine vision systems.

Strength testing: through the use of strength testing instruments, such as electronic tensile machine, multi-functional testing machine, וכו ', to measure the tensile strength of the yarn paper, compressive strength and other indicators.

Testing of rupture strength and flexural strength: By using rupture strength tester and flexural strength tester to measure the performance of the yarn paper such as rupture strength and flexural strength.

Wet strength testing: By using wet strength testing instruments, such as wet strength tester, environmental humidity test box, וכו ', to measure the strength of the yarn paper in a humid environment.

Tensile strength and elongation at break detection: by using a tensile testing machine to measure the tensile strength and elongation at break and other indicators of the yarn paper.

Packaging performance testing: By using packaging performance testing instruments, such as breakage tester, water tightness tester, וכו ', to measure the packaging performance of the yarn made of yarn paper.

Environmental protection testing: through the use of environmental testing instruments, such as volatile organic compounds tester, heavy metal tester, chloride ion tester, וכו ', to measure the content of volatile organic compounds, מתכות כבדות, chloride ions and other harmful substances in the yarn paper.

Thickness meter: Used to measure the thickness of the yarn paper and check the uniformity by laser measurement or machine measurement method. Manual thickness gauges usually use hand-held thickness measuring instruments, and automatic thickness gauges usually use laser triangulation to measure thickness.

Wet strength tester: Used to measure the strength of yarn paper in humid environment, can simulate humid climate and environment.

Tensile testing machine: used to measure the tensile strength and elongation at break of yarn paper and other indicators.

Corrugated altimeter: used to measure the corrugated height and strength of yarn paper to test its protection performance.

Packaging performance test instrument: including breakage tester, water tightness tester, וכו ', used to measure the packaging performance of yarn made of yarn paper.

Environmental testing instruments: such as volatile organic compounds tester, heavy metal tester, chloride ion tester, וכו ', used to measure the content of harmful substances in yarn paper.
