The paper industry continuously seeks to improve the efficiency and environmental footprint of its recycling processes. A key area of focus is the deinking and bleaching of recycled paper to achieve desired brightness and ink removal rates. Research indicates that compounds like Sodium Percarbonate and Sodium Perborate Tetrahydrate offer significant advantages over traditional methods, making them attractive for manufacturers looking to buy advanced recycling chemicals.

Traditional paper recycling often relies on a combination of sodium hydroxide for pulping and hydrogen peroxide for bleaching and ink detachment. While effective, hydrogen peroxide requires specific alkaline conditions to activate its perhydroxyl anion, necessitating additional chemical inputs. Moreover, handling concentrated hydrogen peroxide poses safety and storage challenges for many mills. As a supplier of alternative solutions, we highlight the benefits of solid peroxide compounds.

Studies have shown that both Sodium Percarbonate and Sodium Perborate Tetrahydrate can be used effectively in repulping and flotation deinking processes. Notably, these compounds are alkaline in nature, meaning they can contribute to the necessary pH levels for bleaching and ink removal without the need for additional alkaline agents like sodium hydroxide. This can simplify the chemical process and potentially reduce costs for paper manufacturers.

Research suggests that Sodium Percarbonate, in particular, has demonstrated superior performance in increasing ISO brightness and ink elimination ratios, often outperforming hydrogen peroxide under similar conditions, especially at lower repulping temperatures (45-50°C). Sodium Perborate Tetrahydrate also contributes positively to brightness and ink removal, though sometimes to a lesser extent than percarbonate. For paper mills seeking to buy these chemicals, understanding these performance nuances is critical for optimizing their operations.

A significant advantage cited for both Sodium Percarbonate and Sodium Perborate Tetrahydrate is their solid form. This makes them easier and safer to store and handle than liquid hydrogen peroxide, which requires specialized equipment and stringent safety protocols. For companies involved in bulk chemical procurement for paper recycling, these handling benefits translate to reduced operational risks and potentially lower infrastructure investment.

In conclusion, incorporating Sodium Percarbonate and Sodium Perborate Tetrahydrate into paper recycling processes can lead to improved brightness, enhanced ink removal, and simplified chemical management. As a supplier committed to innovation in the chemical industry, we offer these advanced compounds. Paper manufacturers looking to buy these chemicals to optimize their recycling efforts are encouraged to consult with us for product specifications and procurement details.
