What are the paper thickness measurement tools?

Thickness indicates the thickness of the paper, which refers to the thickness of the paper or cardboard directly measured under a certain pressure between the two measuring plates, measured in mm or m. Generally, the thickness directly affects the opacity of the paper, and the greater the thickness, the better the opacity. Uniformity of thickness is especially good for paper, especially if you put many pieces of paper of the same thickness on top of each other, measure the thickness of the stack with a scale, divide the thickness by the amount of paper, remember to fold it tightly at one point, otherwise the data will be wrong, because if you don't, there will be gaps between the papers!

Importantly, uneven thickness affects the loss of gloss and whiteness, as well as the instability of tonality and color reproduction. Paper and cardboard are generally distinguished by their weight and thickness.

According to the national standard, the quantitative amount is less than 225g m2 and the thickness is less than the paper; The quantity greater than 225g m2 and the thickness greater than are called cardboard. Thickness indicates the thickness of paper and cardboard, and basically all paper product manufacturers will be equipped with a tool to measure the thickness of paper - CHY-U paper thickness tester.

CHY-U Paper Thickness Tester.

What tool is used to measure paper thickness?

The paper thickness tester CHY-U, a tool for measuring paper thickness, fully meets the GB paper and cardboard thickness determination method, and is suitable for accurate measurement of the thickness of various hard and soft materials such as paper, film, composite film, metal foil and so on within the range of 2mm. The tool for measuring paper thickness is also called paper thickness gauge, paper thickness tester, paper thickness testing instrument, the instrument is equipped with a micro printer, real-time data display, automatic statistics, printing, maximum, minimum, average value and each measurement result, convenient for users to analyze data, the appearance of the instrument is beautiful, new and stable, and is favored by quality inspection institutions, colleges and universities, and production enterprises.

A tool that measures the thickness of the paper inspects the sample – the paper.

The CHY-U paper thickness tester, a tool for measuring paper thickness, uses the contact test principle to intercept a certain size of specimen, and the thickness gauge head automatically lands on the specimen, relying on a fixed pressure and a fixed contact area to test the thickness value of the specimen.

When measuring paper thickness, the old method is to measure the thickness of 100 sheets of paper with the help of a tool, and then divide by 100 to get the thickness of 1 sheet. Times are evolving, and now there are more high-tech technologies.

Shenzhen Dacheng Precision Co., Ltd. has developed X-ray areal densitometry, infrared thickness gauge and other professional equipment to achieve first-class non-destructive testing, through which the thickness, areal density and moisture content consistency of the paper can be measured.

There are calipers that measure the thickness of the paper, and there are more accurate electronic scales, which can be accurate to 1 gram.

Uniformity of thickness is especially good for paper, especially if you put many pieces of paper of the same thickness on top of each other, measure the thickness of the stack with a scale, divide the thickness by the amount of paper, remember to fold it tightly at one point, otherwise the data will be wrong, because if you don't, there will be gaps between the papers! Its important, uneven thickness.

Scientific averaging: count 20 or 50 or even 100 sheets, then measure the thickness with a ruler, and then divide by the number of sheets, and the result is the average thickness. Scientific Instrumentation Law:

Use higher precision measuring instruments such as vernier calipers, micrometers, etc. The micrometer is a spiral micrometer, which can be accurate to a measurement range of a few centimeters. <

1. Scientific averaging method: count 20 or 50 or even 100 sheets, then measure the thickness with a ruler, and then divide by the number of papers, and the result is the average thickness.

2. Scientific instrument method: use higher precision measuring instruments, such as vernier calipers, micrometers, etc. The micrometer is a spiral micrometer, which can be accurate to a measurement range of a few centimeters.

What are the basic measurement methods needed to accurately measure the thickness of a piece of paper?

To accurately measure the thickness of a piece of paper, you need to use 1Accumulation method, 2Direct measurement of hair. We can take 1000 sheets of paper, measure the thickness of 1000 sheets directly, and then divide by 1000 to get the thickness of each sheet, dear

What are the basic measurements needed to measure room temperature with mercury thermometers?

Averaging method for multiple measurements.

1. Scientific averaging method: count 20 or 50 or even 100 sheets, then measure the thickness with a ruler, and then divide by the number of papers to be the average thickness;

2. Scientific instrument method: use higher precision measuring instruments: vernier calipers, micrometers, etc.

Method: Take 100 sheets of paper, measure their thickness, and then divide this thickness by 100, which is the thickness of each sheet.

Example: Knowing the tonnage of paper, calculating the number of sheets. For example, we say a piece of 70g double offset paper.

The size is 787*1092, there is 1 ton, I want to know how many sheets of 70g double offset paper came.

Calculation: A piece of paper 787mm*1092mm is the degree of positive chaos, and 70 is the gram weight after multiplication.

i.e. 70g m2

So multiply these numbers to see that a piece of paper is.

Then divide it with a ton, i.e. Zhang.

1. Under the specified static load, select the thickness gauge that meets the accuracy requirements.

2. The thickness gauge is equipped with two circular measuring surfaces parallel to each other, and the pressure between the measuring surfaces is set at 90 to 110 kPa during the measurement process, and the method of constant load is adopted to ensure that the pressure between the two measuring surfaces is uniform and its deviation is within the specified range.

3. The pressure of the setting is different, the compression degree of the paper is different, and the measured value is also different. According to the test requirements, paper or cardboard is placed between the two measuring surfaces for measurement.

4. Measure the thickness of a single sheet of paper or a stack of sheets, and the thickness of a single layer or a layer of paper is used to represent the thickness measurement results of the paper.
