נייר לוח לבן הוא חומר נייר הדפסה נפוץ, משמש בדרך כלל להכנת דפי ספרים, עלוני פרסום, אלבומי תמונות, magazines and other printed matter.

ביצועים של זיהוי
It needs to detect the following major performances:

Whiteness: the whiteboard paper needs to have a high whiteness to ensure the bright color and clear image of the printed matter. The detection of whiteness can be carried out by measuring the reflected brightness and chromaticity coordinates of the paper surface.

Printing quality: The printing quality of whiteboard paper includes image clarity, color reduction and printing speed. ניתן לבצע את בדיקת איכות ההדפסה על ידי בדיקת אפקט ההדפסה, בהירות קו, הפחתת צבע ואינדיקטורים אחרים של הדפסה.

Thickness and uniformity: The thickness and uniformity of the whiteboard will directly affect the printing effect and quality of the printed matter. The detection of thickness and uniformity can be carried out by measuring the thickness, density and basic weight of the paper.

Strength: The whiteboard paper needs to have a certain strength to ensure the stability and durability of the printed matter. זיהוי חוזק יכול להתבצע על ידי מדידת חוזק המתיחה, flexural strength, compressive strength and other indicators of paper.

Smoothness: the whiteboard paper needs to have a certain smoothness to ensure the printing effect and quality of the printed matter. Smoothness detection can be carried out by measuring the gloss, smoothness, roughness and other indicators of the surface of the paper.

שמירה על איכות סביבה: white board paper needs to meet environmental protection standards, אינו מכיל חומרים מזיקים, ללא זיהום לסביבה. איתור הגנת הסביבה יכול להתבצע על ידי מדידת התרכובות האורגניות הנדיפות, מתכות כבדות, יוני כלוריד וחומרי הלבנה ניאון של נייר.

היקף היישום: The use of whiteboard paper is mainly in high quality printed matter, such as book pages, עלוני פרסום, אלבומי תמונות, כתבי עת, וכו. זיהוי היקף היישום יכול להתבצע על ידי מדידת הסביבה הרלוונטית של הנייר, the applicable printing variety and the applicable processing technology.

ציפוי משטח: Whiteboard paper usually needs to be coated to increase its surface hardness, wear resistance and printing quality. The performance test of surface coating can be carried out by measuring the uniformity, קַשִׁיוּת, התנגדות ללבוש, adhesion and other indicators of the coating.

Slidability: The slidability of whiteboard paper refers to its smoothness on a high-speed printing machine and its ability to resist paper jams. The detection of sliding can be carried out by measuring the sliding coefficient of paper, surface smoothness, surface softness and other indicators.

Processability: white board paper needs to have a certain degree of processability to ensure that it can be smoothly carried out in the printing and subsequent processing process. The detection of machinability can be carried out by measuring the surface hardness, surface roughness, suitable processing technology and other indicators of paper.

Anti-aging: the whiteboard paper needs to have good anti-aging to ensure that the printed matter is not easy to fade or yellow in long-term use. The detection of anti-aging can be carried out by measuring the pH of paper, the color difference value after ultraviolet radiation and other indicators.

These performance indicators are the key content of whiteboard paper detection, דרישות ותקנים שונים לשימוש ישפיעו גם על תקני הגילוי ושיטות הנייר.
