Description
Technical Field
The present invention relates to a glass sheet interleaving paper used by being inserted between glass sheets.
Background
In a distribution process and a manufacturing process in which a plurality of glass plates for flat panel displays such as liquid crystal panel displays and plasma panel displays are stacked and stored and transported, glass plate interleaving paper is used to protect the glass plates.
Glass plates used as substrate materials for flat panel displays are required to have higher surface smoothness than ordinary architectural and vehicular glass plates and the like. Since a glass plate for a flat panel display has a thin film of an electronic component or the like on the surface of the glass plate, the surface of the glass plate is required to have extremely high cleanliness and surface flatness as compared with those of glass plates used for other applications. Even when a glass plate used in such an application is slightly damaged or contaminated by contact with another glass plate or the like, the performance as a display may be poor.
In recent years, as glass sheets have been increased in size and mass-produced, in order to increase conveyance efficiency, the glass sheets have been conveyed while being overlapped as much as possible, and the contact area with the glass sheet lining paper tends to increase. When the contact area or contact pressure between the glass plate and the glass plate lining paper increases, the possibility of generating a flaw due to foreign matter or the like present in the glass plate lining paper increases. Further, the resin components and the like contained in the glass sheet lining paper are transferred, and the possibility of staining the surface of the glass sheet is also increased.
Therefore, high quality is required for the glass sheet interleaving paper inserted between the glass sheets.
In order to reduce scratches and contamination caused by glass sheet interleaving paper, for example, patent document 1 discloses interleaving paper for glass sheets, which contains a pulp raw material as a main component. The interleaving paper for glass plates is characterized in that: the gram weight (plateau weight) is 30-60 g/m2The maximum difference in paper thickness between adjacent measurement points is 8 μm or less and the difference between the maximum value and the minimum value of the paper thickness is 16 μm or less.
Patent document 2 discloses a technique of regulating pulp blending so that the compression work amount becomes 0.15J/m2The above-mentioned composition has a compression recovery rate of 50% or more, and thus the cushioning property is improved and the occurrence of scratches on the surface of the glass sheet is suppressed.

Problems to be solved by the invention
The above-described conventional art realizes prevention of damage, improvement of adhesion, contamination, and the like by improving physical properties and forms of the glass sheet mount. However, since the number of production steps increases or new raw materials and production facilities are required, there is room for further improvement in production control and productivity.
The present invention has been made in view of such a situation. The invention provides a glass plate lining paper, which can restrain the damage of the surface of a glass plate in the circulation process and the manufacturing step of stacking and storing and transporting a plurality of glass plates.
Technical scheme for solving problems
In order to solve the above problems, the present inventors have found the following, and have obtained the present invention: in contrast to the conventional method, the texture (ground lamination) of the glass sheet lining paper is not made uniform, and the occurrence of scratches on the surface of the glass sheet can be suppressed. That is, the present invention has the following configuration.
(1) A glass sheet lining paper which is produced by using cellulose pulp as a main component and cellulose pulp having a beating degree (beating degree) of 200 to 700mlcsf measured according to JIS P8121-2:2012 and which has a grammage of 10 to 100g/m2The texture index measured using a 3D chip analyzer (3D シートアナライザー) was 15 or less.
(2) The glass sheet lining paper according to the above (1), wherein the glass sheet lining paper has a thickness of 25 to 250 μm and a density of 0.4 to 1.2g/cm3。
Effects of the invention
The glass plate lining paper of the invention can inhibit the damage of the surface of a glass plate in the circulation process of stacking, storing and transporting a plurality of glass plates.
Detailed Description
The embodiments of the present invention are specifically described below. The present invention is not to be interpreted as being limited to these embodiments.
In order to reduce scratches and contamination caused by glass sheet interleaving paper, the present inventors have made studies on the relationship between the production conditions of glass sheet interleaving paper and the damage and contamination of glass sheets by producing the glass sheet interleaving paper under various production conditions. As a result, the following were found: contrary to expectation, when a glass plate lining paper having a relatively poor texture and a non-uniform texture is used, the occurrence of damage and contamination of the glass plate can be suppressed. The result is directed in the opposite direction to the current state of the art.
Therefore, the present inventors have further studied the reason for the above-described results, and considered the following. The thick portion of the glass sheet lining paper resulting from the unevenness of the texture exerts a cushioning effect on the glass sheet due to the thickness thereof. On the other hand, the thinner portion of the glass sheet lining paper reduces the contact pressure between the glass sheet lining paper and the glass sheet. It is assumed that these effects act to improve the damage to the glass sheet in any case.
Further, it was found that, in the glass sheet interleaving paper having a poor texture, since the glass sheet interleaving paper does not contact the entire surface of the glass sheet and a thick portion of the glass sheet interleaving paper mainly contacts the glass sheet, the transfer of the resin component or the like in the glass sheet interleaving paper can be suppressed and the contamination of the glass sheet can be improved.
The contaminants on the surface of the glass sheet contained in the glass sheet lining paper include resin components, which are adhesive substances contained in the glass sheet lining paper. Many of them are natural impurities such as resins contained in wood. When the resin component is contained in an amount of 0.2 mass% or more in particular in the paper, the surface of the glass plate is likely to be contaminated. It is preferably removed as much as possible by washing or the like, but complete removal is difficult.
Next, the present inventors studied to quantify the degree of unevenness in the quality of the glass sheet mount paper which can suppress the occurrence of damage to the glass sheet. As a result, it was found that a 3D chip analyzer manufactured by M/K systems of America was useful for quantifying the unevenness of texture. The 3D flake analyzer was used to investigate the texture index of the glass plate lining paper effective for suppressing damage of the surface of the glass plate. As a result, it was found that it is effective to set the texture index of the glass sheet lining paper to 15 or less, and the present invention was completed.
The glass sheet lining paper of the present embodiment contains cellulose pulp as a main component. As the cellulose pulp used for the glass sheet lining paper, one of various substances or a mixture of two or more of them can be used. Examples of the pulp include chemical pulps such as Kraft Pulp (KP), Sulfite Pulp (SP), and Alkaline Pulp (AP); semichemical pulp such as semichemical pulp (SCP), chemical ground wood pulp (CGP); mechanical pulp such as ground wood pulp (GP), thermo-mechanical pulp (TMP, BCTMP), finely ground wood pulp (RGP); non-wood fiber paper pulp using paper mulberry, daphne giraldii, hemp, kenaf (kenaf) and the like as raw materials. In addition to these, synthetic pulp, synthetic fiber, rayon, and the like may be blended. The wood used for cellulose pulp may be coniferous wood, hardwood wood, or a mixture thereof.
The glass plate lining paper of the present embodiment is made by papermaking from cellulose pulp having a freeness of 200 to 700mlcsf, measured according to JIS P8121-2: 2012.
The degree of beating of the cellulose pulp is set to 200-700 mlcsf in accordance with JIS P8121-2: 2012. The freeness here is a Canadian standard freeness (Canadian standard freeness) according to JIS P8121-2: 2012. Note that, since JIS P8121-2:2012 corresponds to ISO5267-2:2001, the ratio of JIS P8121-2:2012, the same freeness as determined according to ISO5267-2: 2001. By setting the beating degree within the range of 200 to 700mlcsf, the mechanical strength and the processability required for the glass plate lining paper can be obtained. The preferable beating degree is 400-700 mlcsf. In order to adjust the beating degree to 200-700 mlcsf, a known method can be used for beating the pulp.
The gram weight of the glass plate lining paper is 10-100 g/m2The range of (1). More preferably, the gram weight is 35 to 80g/m2. When the gram weight is small, the mass at the time of transportation is small, and therefore, the gram weight is preferably less than 10g/m2In this case, sufficient cushioning properties cannot be imparted. Furthermore, the grammage is greater than 100g/m2In this case, the quality during transportation is not good, which is not preferable. The grammage of the glass sheet lining paper was measured in accordance with JISP 8124.
The thickness of the glass plate lining paper is preferably 25 to 250 μm, and more preferably 60 to 200 μm. In addition, the density of the lining paper of the glass plate is preferably 0.4 to 1.2g/cm3More preferably 0.5 to 1.1g/cm3. The thickness of the glass sheet mount paper andthe density was measured according to JIS P8118.
The glass plate lining paper of the present embodiment has a texture index of 15 or less, which is measured using a 3D sheet analyzer. The 3D sheet analyzer is used for quantitatively measuring the texture of paper. The present inventors have repeatedly studied a method for quantifying the texture of a glass plate lining paper, and as a result, have found that a 3D sheet analyzer manufactured by M/K systems, usa can quantify the texture of a glass plate lining paper with good reproducibility. This apparatus is an optical image of the dispersion state of cellulose fibers in paper, and numerically processes the image to quantify the degree of uniformity.
An index for quantifying texture using the 3D chip analyzer is a texture index. The texture index is calculated as follows.
1) A glass sheet liner was wound around a glass drum and, while rotating, a light source (white light) provided on the drum shaft was irradiated to the glass sheet liner.
2) The light transmitted through the glass plate lining paper was detected by a photodetector, and the intensity of the transmitted light with the number of dots measured as 100,000 dots was classified into 64 intensity classes.
3) Of the 64 intensity levels, the number of degrees (peak value) with the highest intensity was divided by the number of levels having 100 or more degrees, and the product of the number and the number was multiplied by 1/100 to obtain a texture index.
That is, the texture index (the number of the highest degree/the number of the order of 100 or more) x 1/100
The grade of less than 100 degrees cannot determine the texture index of the entire glass sheet lining paper, and is therefore ignored. The greater the maximum number of degrees and the fewer the number of grades having a number of degrees of 100 or more, the greater the quality index, and it can be called a uniform glass sheet lining paper. Conversely, the texture index is smaller for glass sheet liners having a non-uniform texture and a less uniform texture.
The inventors of the present invention studied the relationship between the texture index and the degree of surface damage of a glass sheet. As a result, it has been found that in a specific application such as a flat panel display, in order to suppress damage to the surface of a glass plate to such an extent that no trouble is caused during actual use, it is necessary to set the texture index of a glass plate lining paper to 15 or less. That is, the glass plate mount paper having a texture index of 15 or less, which is measured by a 3D chip analyzer, can be used to suppress the damageability to an acceptable level. The texture index of the glass sheet lining paper is more preferably 10 or less.
As a method for producing a paper from a glass sheet lining paper having a texture index of 15 or less, for example, the following method is available.
(1) The amplitude and the vibration number of the wire vibrating device are reduced.
(2) The vibration of the wire vibrating device is stopped.
(3) The number of the foils (counter blades) of the forming plate is increased to increase the initial dewatering amount.
(4) Increasing the inlet concentration. For example, when the inlet concentration is 0.5%, the inlet concentration is about 1%.
Any of these methods can be used, or a plurality of methods can be used in combination as appropriate. The texture of the obtained glass sheet lining paper varies depending on the type of raw material pulp, the structure of the apparatus, and the like, and therefore, the texture of the glass sheet lining paper produced by changing a plurality of conditions can be measured, and the relationship between the two can be confirmed to set appropriate conditions.
The chemicals to be added to the glass sheet lining paper in the present embodiment are preferably added in a range where the surface of the glass sheet is not contaminated or damaged. For example, various sizing agents (sizing agents) such as aluminum sulfate, sulfuric acid, rosin, styrene-maleic acid, alkenyl succinic anhydride, and alkyl ketene dimer, various paper strength enhancers such as polyacrylamide, drainage yield enhancers, water resistance agents such as polyamide polyamine epichlorohydrin, softeners, antistatic agents, defoaming agents, viscosity control agents, fillers, and dyes can be used. In addition to the above chemicals, water, glass detergent, polyvinyl alcohol, polyacrylamide, starch, and the like may be applied to or impregnated into the front and back surfaces of the glass sheet lining paper.
As the apparatus for coating or impregnating the above-mentioned chemicals, for example, a two-roll size press, a transfer roll Coater (gate roll Coater), a multi-roll Coater (massey Coater), a KCM Coater, a robine mechanical Coater (Champion Machine Coater), etc.), a film transfer size press (Sym size press, a doctor blade metering size press, etc.), a Bill's blade Coater (Standard Coater, differential thickness Coater, cony-Coater), a two-flow Coater, a BEL-BAPA Coater, a bar Coater, a knife Coater, a pneumatic blade Coater, a bar Coater, a calender Coater, etc. can be used.
The manufacturing apparatus and manufacturing conditions for manufacturing the glass sheet interleaving paper of the present embodiment are not particularly limited, and known manufacturing apparatuses and manufacturing conditions can be appropriately selected and used. For example, a fourdrinier wire former, a twin wire former, a cylinder former, or an inclined former can be used to make paper into single-layer or multi-layer paper. In addition, for the purpose of appropriately adjusting the texture and controlling the smoothness of the paper surface and the uniformity in the width direction, an embossing roll (dandy roll) may also be used.
The glass plate interleaving paper of the present embodiment may be subjected to embossing and wrinkling for forming fine irregularities on the surface. The embossing is performed using an embossing machine, a convex-concave die, or the like, and is processed into a shape such as a dot, a dashed line, a straight line, or a wave. As a method of performing the crumpling treatment, a method of peeling and crumpling a bonded sheet using a blade provided on a pressure roll or a dryer in a wet end of a paper making machine is exemplified.

The numerical values of the formulation are based on the mass of the solid or active ingredient. In addition, unless otherwise specified, the paper produced by the paper making process is subjected to measurement or test after being treated in accordance with JIS P8111. The details of measurement of texture index, damage test and damage evaluation are as follows.
