Black card technical indicators
1. Black card board grammage refers to the weight of paper per unit area, generally expressed in grams per square meter. It can be converted into the number of grams per square meter according to the length and width specifications of the paper and the number of sheets per order. Quantification is the most basic physical index of paper. Its level of homogeneity influences all physical, mechanical, optical and printing properties of paper.
The various performance indicators of general printing paper, such as thickness, tensile strength, bursting resistance, and opacity, are closely related to the quantification.
If the basis weight of the paper is significantly lower than its standard, it will not only be liable to print defects, but will also be broken due to insufficient mechanical strength. Conversely, if the ration is too high, pulp will be wasted in production And can not guarantee the user's usable area per ton of roll paper. When the ration of a piece of paper and the next piece of paper is different, the printing adjustment work cannot be performed in such a paper interval, and problems such as misregistration and imprinting will occur. When the same piece of paper is unevenly quantified, it is more likely to result in illegible characters and inconsistent color.
2. Black card board tear ability. Tear is the force required to tear a pre-notched specimen to a certain length, expressed in kilotons (tons). The degree of paper breakage is the ability of paper and paperboard to resist cracking.
3. Black cardboard folding resistance. Fold resistance is the number of times that paper and paperboard can withstand 180° reciprocating folding under certain tension. Reciprocating folding times. The degree of folding resistance indicates the ability of the paper to resist folding.
4. Black card board blackness, color index. Whiteness refers to the degree of whiteness of a piece of paper. It is generally expressed as 0-100 degrees (0-100%), 0 degrees is all black, and 100 degrees is extremely white. The general whiteness of paper is above 80,
The whiteness of the paper, which is most suitable for long-term writing by the human eye, is 85-87 degrees. The whiteness of the paper copy paper is generally 88-95 degrees. Chromaticity is the color shade of colored paper, and the degree of shade is generally determined by comparison of standard color samples.
5. Black card board pH (pH). General acidity is below 6.7 acid paper, 7.2±0.5 is neutral paper. High acidity has an adverse effect on the machine. Grass pulp paper is generally acidic paper, bamboo, wood pulp paper is generally neutral paper.
