Embodiment Construction

[0022] A method for predicting the matte degree of paper surface, comprising the following steps;

[0023] Step 1: cutting the transfer film sample, and obtaining the test area S of the transfer film sample;

[0024] Step 2: Pass the transfer film sample cut in step 1 through a light transmittance haze meter to obtain the haze H and light transmittance T of the transfer film sample;

[0025] Step 3: Calculate the matte degree M of the transfer film according to the test area S obtained in step 1, and the haze H and light transmittance T obtained in step 2. The matte degree M is calculated by the following formula:

[0026]

[0027] Where L is the distance between the light transmittance haze meter and the transfer film sample.

[0028] Since the transfer film is directly coated on the paper during the paper production process, the matte degree M of the transfer film is an important factor in determining the matte degree of the finished paper. It is possible to predict the...

Abstract

The invention relates to a method for predicting paper surface matte degree. The method comprises the steps of step 1, performing cutting on a thin film sample and obtaining the test area S of the transferred thin film sample; step 2, obtaining the haze H and the light transmittance T of the transferred thin film sample; and step 3, according to the test area of the step 1, and the haze H and thelight transmittance T of the step 2, calculating the matte degree M of the transferred thin film. The method has the advantages as follows: the transferred thin film is directly coated on paper in thepaper production process, so that the matte degree M of the transferred thin film is an important factor for determining the matte degree of the finished product of paper, so that in the production process, an operator can predict the matte degree of the finished product of paper in the first procedure, a phenomenon that paper is wasted due to poor matte degree of the existing paper finished product is avoided, and energy conservation and emission reduction are achieved, the paper production quality is ensured, and requirements of different paper thicknesses and paper models are met by setting different parameters L.

Description

technical field [0001] The invention relates to a method for predicting the matte degree of paper surface. Background technique [0002] In the fierce market competition, composite aluminum lining paper is mostly used for cigarette lining paper, but the aluminum layer of composite lining paper is thicker, and the amount of aluminum used is larger, which is no longer suitable for the "resource-saving and environment-friendly" society. development trend. As a new, safe and environmentally friendly vacuum aluminized lining paper, it will definitely become the mainstream and direction of future development. [0003] When the composite aluminum lining paper is composited with aluminum, the aluminum foil layer has both sides, the front side is smooth, and the reverse side is polished. It can only be selected on one side, that is, only the bright side is applied, so that the matte effect of the traditional composite aluminum lining paper cannot be replicated. In the existing prod...
