Glass Plate-Interleaving Paper Hard Particle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass plate-interleaving papers fail to completely prevent damage and cracks on the surface of glass plates for flat panel displays, leading to increased failure rates and profitability issues due to disconnection or short circuits during manufacturing processes.
Innovation Solution
Development of glass plate-interleaving paper with a reduced number of foreign substances having a Mohs hardness of 4 or higher, specifically using wood pulp with fewer than 0.010 foreign substances per square meter, and controlling the paper's basis weight, thickness, and moisture content to minimize surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional glass plate-interleaving paper is used, then the paper provides basic protection during storage and transport, but surface damage and cracks still occur on glass plates due to foreign substances with high Mohs hardness
Solution Approach 1:
The patent extracts and removes foreign substances with Mohs hardness of 4 or higher from the paper surface through careful selection of raw materials and implementation of removal processes, directly addressing the harmful factor causing surface damage to glass plates
Solution Approach 2:
The patent changes the parameter of foreign substance content by specifying that the number of foreign substances with Mohs hardness of 4 or higher must be 0.010 or fewer per square meter, transforming the paper quality to achieve superior protection
2Reliability
If interleaving paper is inserted between glass plates to prevent damage, then basic protection is provided, but minute damage or cracks can still occur leading to disconnection or short circuits in electronic elements
Solution Approach 1:
The patent extracts harmful foreign substances from the paper to achieve a cleaner surface that prevents minute damage and cracks, thereby protecting the integrity of electronic elements and maintaining manufacturing precision
Solution Approach 2:
The patent applies strict parameter control by limiting foreign substances with Mohs hardness of 4 or higher to 0.010 or fewer per square meter, ensuring the paper provides sufficient protection without causing surface defects
3Ease of operation
If glass plates are stored or transported without adequate protection, then handling is simpler, but damage and cracks occur on the glass plate surface
Solution Approach 1:
The patent removes harmful foreign substances from the interleaving paper, enabling simple handling and stacking of glass plates without the risk of surface damage from hard particles during transport and storage operations

AI summary
The present invention relates to glass plate-interleaving paper, which is used for a glass plate for use in a display, and in which wood pulp is used as a raw material, and the number of foreign substances having a Mohs hardness of 4 or higher present on the surface of the glass plate-interleaving paper is fewer than 0.010 per square meter. Even if the glass plate-interleaving paper of the present invention is used in a conventional way as glass plate-interleaving paper with respect to a glass plate used as a substrate material for a flat panel display in which high cleanliness and high quality are required, the glass plate-interleaving paper is able to prevent damage or cracks occurring on the surface of the glass plate.
