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 de détection
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.

Résistance du papier: 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, la force des larmes, folding resistance and other indicators of 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.

Durabilité: 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.

Protection environnementale: carbon-free base paper needs to meet environmental protection standards, ne contient pas de substances nocives, pas de pollution pour l'environnement. The detection of environmental protection can be carried out by measuring the volatile organic compounds, métaux lourds, chloride ions and fluorescent whitening agents of paper.

Champ d'application: The use of carbon-free base paper is mainly in the production of carbon paper or carbon tape and other office supplies. La détection du champ d'application peut être effectuée en mesurant l'environnement applicable du papier, the applicable copy model and the applicable copy paper.

These performance indicators are the key content of carbon-free base paper detection, différentes exigences et normes d'utilisation affecteront également les normes et méthodes de détection du papier.
