The Importance of Using Calcium Carbonate in the Paper Industry at Zohdy Minerals Egypt

The importance of Using Calcium Carbonate in the Paper Industry is evident through the numerous properties it possesses, which improve the characteristics of paper, as demonstrated by Zohdy Minerals Egypt.

In today’s paper manufacturing process, fillers and dyes are the second most important raw material after fibers, which come in first. Calcium carbonate, talc, kaolin, and bentonite are all commonly used fillers in the paper industry. The paper industry has gradually shifted from acidic to neutral and alkaline processes. As a crucial raw material, calcium carbonate has been increasingly used in paper manufacturing, a specialty of Zohdy Minerals Egypt.If you require Calcium Carbonate, you can contact Zohdy Minerals Egypt.

What is the Calcium Carbonate Used at Zohdy Minerals Egypt? Calcium carbonate is a white inorganic chemical composed of calcium and carbon, with the chemical formula “CaCO₃.” It’s a common substance found naturally in many rocks, such as limestone and chalk, and can also be produced synthetically from dolomite due to its properties. Because it possesses numerous properties, calcium carbonate is used in various industries, including white cement, paper, paints, ceramics, food, and pharmaceuticals.

Generally, calcium carbonate and other fillers used in the paper industry at Zohdy Minerals Egypt consistently and noticeably improve the paper’s hardness, density, strength, whiteness, smoothness, anti-aging, yellowing resistance, brittleness resistance, and other properties. Many paper companies also work on improving the paper-making process and use calcium carbonate. They do this by constantly enhancing calcium carbonate through crushing, modification, compounding, and other processes.

In recent years, the powder network officials at Zohdy Minerals Egypt have organized and shared their production technology for paper companies that use calcium carbonate and will continue to do so with all relevant paper companies.If you require Calcium Carbonate, you can contact Zohdy Minerals Egypt.

Benefits of Using Calcium Carbonate in Paper Quality

Calcium carbonate can be used in the production of a variety of paper types, such as writing paper, printing paper, and packaging paper. It is the most common material used in the paper industry, making up about 30% of the total materials used.

Generally, using calcium carbonate in paper manufacturing offers several benefits, such as:

• Improved Strength and Hardness: Calcium carbonate helps increase the paper’s strength and hardness, making it more tear- and fold-resistant during daily use, as is the case with writing and printing paper. Calcium carbonate also helps prevent paper from tearing or creasing when packaging products.
• Improved Whiteness: Calcium carbonate reflects light well, making the paper whiter and helping it permanently maintain its brightness and luster.
• Reduced Cost: Calcium carbonate is an inexpensive material, making it an economical choice for paper manufacturing in general.
• Environmental Protection: Using calcium carbonate in paper manufacturing reduces energy consumption and carbon dioxide emissions because the drying temperature of paper containing calcium carbonate is lower. Using calcium carbonate also improves the recyclability of paper due to its lower fiber content.
• Improved Printing and Operational Properties: Using calcium carbonate in paper manufacturing helps improve the paper’s brightness, absorption, and slip properties, which, in turn, improves its printing and operational characteristics.

The quality of paper sheets depends on the use of specific proportions of calcium carbonate, which affect the properties of the final product. There are different types of calcium carbonate used in paper manufacturing, such as heavy calcium carbonate, light calcium carbonate, nano calcium carbonate, mixed calcium carbonate, modified calcium carbonate, fibrous calcium carbonate, and clay calcium carbonate. Each type has its own properties and applications. If you require Calcium Carbonate, you can contact Zohdy Minerals Egypt.

The percentage of calcium carbonate in high-quality paper depends on the paper type and the required properties. Generally, the following should be considered when increasing calcium carbonate:

• The higher the percentage of calcium carbonate in the paper, the higher its whiteness, gloss, and smoothness, but its strength and sizing effect may decrease.
• There must be an appropriate balance between calcium carbonate, other fibers, and additives in the paper manufacturing process.
• The percentage of calcium carbonate in high-quality paper can range from 10% to 30% of the paper’s weight, depending on the type of calcium carbonate and how it’s added during manufacturing.
• High-quality printing papers can contain 15–20% ground calcium carbonate, 10–15% light calcium carbonate, or 5–10% nano calcium carbonate.
• Specific ratios must be adhered to, as an increase in calcium carbonate can reduce paper strength, sizing effect, and increase water retention.

Calcium Carbonate Percentage in Paper Manufacturing

• Improved Whiteness and Gloss: Calcium carbonate increases the whiteness of paper and gives it an eye-catching shine.
• Increased Opacity: Calcium carbonate contributes to increased paper opacity, making it ideal for double-sided printing.
• Improved Surface Smoothness: Calcium carbonate gives the paper surface superior smoothness, which improves printing quality.
• Reduced Production Costs: Calcium carbonate helps reduce wood pulp consumption, which lowers overall production costs.

Applications of Calcium Carbonate in Paper Manufacturing

Calcium carbonate is used in multiple stages of paper manufacturing. Each application aims to achieve specific properties.

• As a Filler: Calcium carbonate is added to the paper pulp. This increases mass and improves optical properties.
• As a Coating Pigment: It is used in coating layers to improve the paper’s printability.
• In Cardboard Production: It helps strengthen cardboard sheets, increasing their durability and resistance.
• In Newsprint Production: It improves the quality of newsprint, making the print clearer and sharper.
