Cobb paper is a special purpose paper that is often used to make bobbins in textiles to protect the yarn and facilitate storage and transportation. Cobb paper is mainly made of wood pulp and waste paper, which has good flexibility, water resistance and tear resistance.
Detection performance
The performance testing of bobbin paper usually includes the following aspects:
Detection of basis weight: Calculate the basis weight per square meter by weighing the weight of a bobbin paper sample of a certain size. Use a precision electronic scale or balance to measure.
Inspection of thickness and uniformity: measure the thickness of bobbin paper by using manual or automatic Thickness Gauge, and inspect the uniformity by laser measurement or machine measurement method. 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: measure the tensile strength, compressive strength and other indicators of the bobbin paper by using strength testing instruments, such as electronic tensile machines, multi-functional testing machines, etc.
Detection of bursting strength and folding strength: measure the bursting strength and folding strength of bobbin paper by using a bursting strength Tester and a folding strength Tester.
Wet strength testing : measure the strength of bobbin paper in a humid environment by using wet strength testing instruments, such as wet strength Testers, environmental humidity Test Chambers, etc.
Testing of tensile strength and elongation at break: measure the tensile strength and elongation at break of bobbin paper by using a Tensile Testing Machine.
Packaging performance testing: use packaging performance testing instruments, such as damage Testers, water tightness Testers, etc., to measure the packaging performance of bobbins made of bobbin paper.
Environmental testing: use environmental testing instruments, such as volatile organic compound Testers, heavy metal Testers, chloride ion Testers, etc., to measure the content of volatile organic compounds, heavy metals, chloride ions and other harmful substances in bobbin paper.
Testing equipment
Performance testing of bobbin paper usually requires the use of some specialized instruments and equipment, including but not limited to the following:
Basis Weight Detector: It is used to measure the weight of bobbin paper samples of a certain size and calculate the basis weight per square meter.
Thickness gauge: used to measure the thickness of bobbin paper, and to detect the uniformity by laser measurement or machine measurement method. Manual Thickness Gauges typically use hand-held thickness measuring instruments, and automatic Thickness Gauges typically use laser triangulation to measure thickness.
Wet Strength Tester: It is used to measure the strength of bobbin paper in a wet environment, which can simulate a humid climate and environment.
Tensile testing machine: used to measure the tensile strength and elongation at break of bobbin paper.
Corrugated height gauge: used to measure the corrugated height and corrugated strength of bobbin paper to detect its protective performance.
Packaging performance testing instruments : including breakage Tester, water tightness Tester, etc., used to measure the packaging performance of bobbins made of bobbin paper.
Environmental testing instruments: such as volatile organic compound Tester, heavy metal Tester, chloride ion Tester, etc., used to measure the content of harmful substances in bobbin paper.
The above instruments and equipment can be used comprehensively to test the basis weight, thickness, strength, protection performance, packaging performance, environmental protection performance and other aspects of bobbin paper. In the specific testing process, it is necessary to select appropriate instruments and methods according to the specific use and requirements of the bobbin paper to ensure the accuracy and reliability of the testing results.
