Carbon-free base paper is a special printing paper that is usually used to make office supplies such as carbon paper or carbon tape. It has the characteristics of duplicating without toner or carbon strip, which can greatly improve work efficiency and save costs.

Performance of detection
Carbon-free base paper needs to have the following main properties:

Carbonization: Carbonization of carbon-free base paper is one of its important performance indicators, which determines the effect and quality of paper in the copy. Carbonization detection can be carried out by measuring the carbonization rate and carbon blackness on the surface of the paper.

Printing quality: The printing quality of carbon-free base paper includes image clarity, color reduction and printing speed. The inspection of printing quality can be carried out by checking the printing effect, line clarity, color reduction and other indicators of printing.

Paper strength: Carbon-free base paper needs to have a certain strength to ensure its stability and durability. Strength detection can be carried out by measuring the tensile strength, tear strength, folding resistance and other indicators of paper.

The main test performance of carbon-free base paper

Paper thickness and uniformity: The thickness and uniformity of carbon-free base paper will directly affect the printing effect and quality of printed matter. The detection of thickness and uniformity can be carried out by measuring indicators such as the thickness of the paper, the base weight and the thickness difference.

Durability: Carbon-free base paper needs to have a certain durability to ensure that the words and patterns are not easy to fall off and blur after copying. Durability testing can be carried out by measuring the friction resistance and water resistance of the paper.

Environmental protection: carbon-free base paper needs to meet environmental protection standards, does not contain harmful substances, no pollution to the environment. The detection of environmental protection can be carried out by measuring the volatile organic compounds, heavy metals, chloride ions and fluorescent whitening agents of paper.

Scope of application: The use of carbon-free base paper is mainly in the production of carbon paper or carbon tape and other office supplies. The detection of the scope of application can be carried out by measuring the applicable environment of the paper, the applicable copy model and the applicable copy paper.

These performance indicators are the key content of carbon-free base paper detection, different use requirements and standards will also affect the detection standards and methods of paper.
