GREENLINETM caustic soda in flakes, is an inorganic chemical that belongs to the strongest bases. Energy used to produce GREENLINETM Caustic Soda is covered by guarantees of origin of energy from renewable energy sources. They are issued only for energy produced from renewable sources, which results in a significant reduction of CO2 to the atmosphere. also GREENLINETM Caustic Soda is produced by membrane electrolysis, which is currently the most modern technology in the world. This technology uses significantly less energy compared to other methods for producing sodium hydroxide.
GREENLINETM flaked caustic soda (solid sodium hydroxide) is a white, crystalline substance. It has very good hygroscopic properties. It dissolves perfectly in water, forming soda lye. It is a substance with corrosive properties, the formation of which is accompanied by the release of significant amounts of heat.
In addition to the energy used for production of GREENLINETM Caustic Soda is covered by guarantees of origin of energy from renewable sources, the product is distinguished from competing products by the low content of chlorides (<200 ppm) and iron (<15 ppm). In the production process of GREENLINETM Caustic Soda only inorganic compounds that do not contain animal or vegetable substances are used. As a result, the product can meet the Kosher and Halal requirements.
Sodium hydroxide in a flaked form is successfully used in industries such as chemistry, textiles, household chemicals, pulp and paper, petrochemical, pharmaceutical, rubber and many others. In the food industry, the product is involved e.g. in the washing process of production installations used for producing food.
Flaked caustic soda as one of the basic chemical raw materials is used in almost every industry. In the cosmetics industry, the product is used in the production of hard (solid) soap, cleaning agents, exfoliating masks (peeling and chemical dermabrasion) and aseptic products.
In the petrochemical industry, sodium hydroxide is used to refine crude oil, mineral oils, pitch and asphalt, and extract shale gas. In refineries and coking plants, caustic soda is used to modify products derived from coal coking. In the metallurgy and metallurgical industries, caustic soda is involved in the process of obtaining aluminium from bauxite processing.
Caustic soda is also widely used in the paper and cellulose industry in the production of wood pulp for the production of paper or regenerated cellulose fibres. Along with sodium sulfate, it is a key component of the white alcohol solution used to separate lignin from cellulose fibres in the Kraft process. It also plays an important role in several later stages of the bleaching process of the brown paper pulp resulting from the pulping process. These steps include oxygen delignification, oxidative extraction and simple extraction, all of which require a strong alkaline environment with a pH> 10.5 at the end of the steps.
In the construction industry, caustic soda is used in some plasticizers for cement mixes. It helps to homogenize cement mixes, preventing sand and cement segregation, reducing the amount of water needed for mixing. Caustic soda is also used in the production of water glass. It is an important raw material in the process of producing pigments and dyes for paints – e.g. titanium white.
Caustic soda (sodium hydroxide) is an important ingredient in the production of surfactants, washing liquids and powders, degreasing and water softening powders and liquids. In a liquid form, it is a component of various types of detergents. In the textile industry, it is used in the production of dyes and artificial silk. In water treatment processes, by increasing the pH, it makes the water less corrosive to the water system and further reduces the content of lead, copper and other toxic metals that can dissolve in drinking water.
Caustic soda in both solid (flakes) and aqueous solution (soda lye) is widely used in agriculture. It is used, among others, in animal husbandry for washing and disinfection of farm rooms (stables, barns, piggeries, poultry houses, warehouses), milking equipment and tanks for transport and storage of dairy products. In fruit growing, the product is used to combat fruit tree diseases (including fruit tree cancer) and to protect vines, while in bee-keeping it is used to clean hives.
GREENLINETM Flaked caustic soda due to environmentally friendly production technology and guarantees of origin of renewable energy, is used in the production processes of the most demanding customers implementing the strategy of reducing the carbon footprint in the entire supply chain. Manufacturers belonging to this group represent various industries, where Soda GREENLINETM Caustic Soda meets both the most stringent quality requirements and those regarding the implementation of sustainable development goals.
