Chlorine 1 kg

Chlorinated lime disinfectant (Chlorka), 1000 g

A powdery, corrosive product (bleaching lime) that partially dissolves in water and releases chlorine; it is used to manufacture disinfectants and bleaching agents, as well as for disinfecting and bleaching various surfaces in dry form or as an aqueous solution. Chlorinated lime is a mixture of calcium hypochlorite, calcium chloride, calcium hydroxide (slaked lime), and water of crystallization. Chlorinated lime is used to treat hard furniture, sanitary equipment, household items, tableware, vehicles, harvesting equipment, indoor surfaces, medical waste, garbage, and air filters. For disinfection purposes, bleaching powder is used in the form of bleached, unbleached, and activated solutions, as well as in the form of dry powder. Bleached disinfectant solutions are used to decontaminate objects in the presence of diseases caused by more resistant pathogens (anthrax, tuberculosis, hepatitis). For general disinfection—such as secretions from infectious patients, food scraps, trash, and bodily fluids—unbleached solutions or the powdered form are used. Chlorine has a strong oxidizing effect, which may lead to a reduction in the strength of fabrics and corrosion of metal products.

Advantages

• This product has a wide range of applications
• The product effectively removes limescale and pathogenic microorganisms
• Chlorine lime solutions have bactericidal, virucidal, fungicidal, and sporicidal properties
• A solution of this product effectively destroys resistant bacterial and spore-forming microorganisms
• The product is highly effective in cleaning and disinfecting domestic and industrial wastewater

Instructions, dosage, method, and specifics of use

It should be noted that chlorine is active exclusively in a moist environment; therefore, Chlorka in powder form must be applied to pre-moistened surfaces. First, a stock solution is prepared from Chlorka, which subsequently serves as the basis for preparing working solutions.

To prepare a stock solution of bleaching powder (a 10–20% solution), pour 1–2 kg of the dry product into an enameled container with a small amount of water and stir with a wooden spatula until a homogeneous mixture is obtained. Then bring the liquid volume to 10 liters, stir until a homogeneous mixture is obtained, and leave for 24 hours in an enameled container with a lid, stirring periodically for the first 4 hours. Carefully pour the resulting substance into a labeled, sealable glass or enameled container. The solution has a shelf life of 5–7 days. Working solutions of bleaching powder in various concentrations are prepared from this disinfectant. These solutions have a shorter shelf life—ranging from 1 to 3–4 days—after which they lose their effectiveness; therefore, it is recommended to mix the ingredients immediately before use. Working disinfectant solutions containing 0.25%, 0.5%, 1%, 2%, 3%, or 5% of the active ingredient are used to disinfect specific items. To prepare them, a 10% chlorine solution is diluted with water according to the desired concentration: for example, to obtain 0.5 liters of a 0.5% solution, the initial solution must be diluted with 9.5 liters of liquid.

These solutions are prepared for the following purposes:

• disinfection of hands and equipment (0.25%);
• preventive disinfection of equipment in somatic wards, rinsing dishes, and washing floors (0.5%);
• disinfection of facilities in cases of intestinal infectious diseases, including doors, walls, and floors (1%);
• treatment of cleaning tools, vehicle interiors, and tables (2%);
• disinfection treatment for HIV infection, viral hepatitis (3%);
• disinfection of instruments, surfaces in sanitary facilities, and toilets (5%).

To enhance the disinfecting effect, a special activator—such as ammonium hydroxide—may be used. The amount of activator depends on the weight and active chlorine content of the disinfectant solution at a given concentration.
