الورق خفيف الوزن رقيق, ورق ناعم يستخدم عادة للتغليف, الطباعة والكتابة. Because of its special paper structure and properties.

أداء الكشف
Its detection needs to pay attention to the following main performance:

سمك وكثافة: The thickness and density of lightweight paper will directly affect its stability and use effect. يمكن قياس السماكة والكثافة عن طريق قياس سمك الورق, الكثافة والوزن الأساسي.

قوة الورق: Lightweight paper needs to have a certain strength to ensure stability and durability. يمكن إجراء اختبار القوة عن طريق قياس قوة الشد, قوة الدموع, folding resistance and other indicators.

Paper flexibility: Lightweight paper needs to be flexible to ensure its suitability for use in areas such as packaging and printing. Flexibility can be tested by measuring the number of folds and bending of the paper and other indicators.

التسطيح: Lightweight paper needs to have a certain flatness to ensure stability and printing effect during the printing process. يمكن قياس التسطيح عن طريق قياس نعومة سطح الورق, ارتفاع الريشة وتقوس اللوحة ومؤشرات أخرى.

الخصائص الرئيسية وطرق اختبار الورق الخفيف

Wear resistance of paper: Lightweight paper needs to have certain wear resistance to ensure its durability and use effect. يمكن اختبار مقاومة التآكل عن طريق قياس درجة التآكل وصلابة سطح الورقة.

Air permeability of paper: Lightweight paper needs to have some air permeability to ensure that it is suitable for use in areas such as packaging. The air permeability test can be carried out by measuring the air permeability and water vapor permeability of the paper.

Printing performance of paper: Lightweight paper needs to have certain printing performance to ensure the printing quality of printed matter. The printing performance can be tested by measuring the paper’s water absorption, ink absorption, وضوح الطباعة, color reduction and resistance to printing pollution and other indicators.

Paper environmental protection: lightweight paper needs to meet environmental standards, لا يحتوي على مواد ضارة, لا تلوث للبيئة. يمكن اختبار حماية البيئة عن طريق قياس المركبات العضوية المتطايرة, معادن ثقيلة, أيونات الكلوريد, منيرات الفلورسنت وغيرها من المؤشرات.

نطاق التطبيق: Lightweight paper is used in a very wide range, different uses of lightweight paper need to have different performance requirements. The scope of application can be tested by measuring the applicable environment of paper, applicable packaging items, applicable printing technology and other indicators.

Machinability: Lightweight paper usually needs to be cut, مطوية, punched and other processing, so it needs to have a certain degree of machinability. The machinability can be tested by measuring the performance change and loss of paper in different processing processes.

The above performance indicators are the key content of light paper testing. ستؤثر متطلبات ومعايير الاستخدام المختلفة أيضًا على معايير وطرق اختبار الورق.
