  Measuring Hydrogen Peroxide in the Paper and Pulp Industry   Hydrogen peroxide is one of the most common bleaching agents. It is used as the primary bleaching agent in the textile industry, and is also used in pulp, paper, and many home laundry applications. Alkaline hydrogen peroxide is used as a bleaching agent for the mechanical pulp. The amount of base such as sodium hydroxide is less than that which is used in bleaching chemical pulps and the temperatures are lower.   How Can Hydrogen Peroxide Be Used as a Bleaching Agent?   In the textile industry, it is commonly used for bleaching cotton fabric. The addition of magnesium sulfate in the bleaching formula helps stabilize the bleaching system for cationized cotton, improving whiteness index and fabric strength. In the pulp and fiber industry, hydrogen peroxide is used to eliminate lignin content and achieve high color brightness. The concentration of hydrogen peroxide used affects the degree of whiteness and fa...

  Thermoplastic Polypropylene Carbonate (PPC plastic) is widely used in applications such as non-woven fabrics, agricultural wrapping films, and medical wrapping films. PPC plastic is notable for being fully recyclable and biodegradable, making it a leading material in terms of environmental friendliness. The complete decomposition of PPC plastic contributes significantly to its eco-friendly reputation. Up-to-date information on the mechanical properties, chemical properties, formation, and decomposition processes of PPC plastic is crucial for manufacturers to devise the most optimal production plans. This valuable information will be detailed below.   1. What is Polypropylene Carbonate?   1.1 Definition of Polypropylene Carbonate   Polypropylene Carbonate , commonly known as PPC plastic, is a thermoplastic material and part of the carbon sequestration group.
