Uses and Applications
Ammonium persulphate in the food industry
Ammonium persulphate is used in the food industry as an oxidising agent. It improves the gluten structure of dough and leads to improved elasticity and dough strength. It also increases the volume ft he dough and optimises the texture ft he end product. Ammonium persulphate is also used as a bleaching agent for baked goods such as white bread.
Ammonium persulphate in the paper industry
Ammonium persulphate acts as a bleaching agent in pulp and paper production. It is also used as a strong oxidising agent that breaks down organic impurities and thus improves the quality of the pulp.
The substance is also used as a dispersing agent to distribute fibres and fillers evenly in the pulp (mixture of water and fibres), which leads to better paper quality.
Ammonium persulphate modifies the surface chemistry of cellulose fibres, increasing their bonding capacity and thus the strength ft he paper.
Ammonium persulphate in the water industry
Ammonium persulphate oxidises organic and inorganic impurities in water. Harmful substances such as phenols, pesticides, colourants and other organic compounds in drinking and waste water or in water systems such as swimming pools are broken down and bacteria, viruses and fungi are killed.
Ammonium persulphate in the construction industry
Ammonium persulphate is used as an additive in concrete mixes to improve the strength and durability of the concrete. It is also used in the production of coatings and protective agents for buildings. It acts as an initiator in the polymerisation of coating materials that are applied to concrete, steel and other building materials to protect them from corrosion, water and chemicals. Ammonium persulphate also removes old paints and coatings before new layers are applied.
