Embodiment 1

[0143] figure 1 and figure 2 In the general manufacturing apparatus for glass paper shown in , two showers for washing paper are installed in the middle of the drying section 24 .

[0144] With such a manufacturing apparatus, the raw pulp is used as a raw material, and the paper is rinsed with pure water in the drying section 24 and dried to manufacture glass paper. In addition, in this example, the calendering process in the calendering part 26 was not performed.

[0145] The prepared glass paper is cut into slices according to the size of the glass plate described later, and the glass paper is analyzed by using known methods of ICP (Inductively Coupled Plasma) mass spectrometry and ICP emission spectrometry content of metal elements.

[0146] As a result, the content of the metal element in the glass paper was 0.08% by mass.

Embodiment 2

[0151] figure 1 and figure 2 In the general glass paper manufacturing apparatus shown in , an ultrasonic irradiation device and a suction device are provided between the cutter 34 and the paper roll 32 .

[0152] With such a production apparatus, the glass paper is manufactured using raw pulp as a raw material, while irradiating the glass paper with ultrasonic waves between the cutter 34 and the winder 36 and suctioning near the position where the ultrasonic waves are irradiated. In addition, in this example, the calendering process in the calendering part 26 was not performed.

[0153] The same analysis as in Example 1 was performed on the prepared glass paper, and the content of the metal element was 0.09% by mass.

Embodiment 3

[0158] use figure 1 and figure 2The manufacturing apparatus of the shown normal glass paper manufactured the glass paper using virgin pulp as a raw material.

[0159] In addition, in this example, the condition of the calendering process in the calendering part 26 was 100 kg / cm.

[0160] The prepared glass paper was cut into slices according to the size of the glass plate described later, and the air permeability of the glass paper was measured in accordance with "JIS P8117:2009", and it was 15 seconds.

[0161] As a reference, this glass paper was analyzed in the same manner as in Example 1, and the content of the metal element was 0.15% by mass.

Abstract

The invention relates to a glass lining paper and a glass plate package body. The glass lining paper is applied during the laminating process of glass plates, wherein the wiring abnormality caused by metal foreign bodies transferred from the glass lining paper is prevented. Meanwhile, the above problem is solved through setting the metal content to be smaller than 0.1 mass% or setting the air permeability to be larger than 10 sec.

Description

technical field [0001] The present invention relates to a glass paper and a glass plate package using the glass paper. Background technique [0002] Glass plates for FPDs (Flat Panel Displays) such as glass plates for construction, glass plates for automobiles, glass plates for plasma displays, and glass plates for liquid crystal displays may have surface flaws or surface damage during storage or transportation. Product defects are prone to occur due to foreign matter contamination. [0003] In particular, since the surface of the glass plate (glass substrate) for FPD has fine electrical wiring (hereinafter also referred to as wiring), electrodes, circuits, and partitions, etc., even if there are very few flaws or contamination on the surface, it will It may cause an abnormality such as disconnection or short circuit. Therefore, glass sheets used in these applications are required to have high surface cleanliness. [0004] Generally, glass plates are stored and transporte...
