Abstract

The invention discloses a disinfection solution used at a low temperature of -18 DEG C, and belongs to the technical field of disinfection solutions. The disinfection solution is specifically prepared from, by weight, 26% of calcium chloride, 1000-2000 ppm of sodium hypochlorite, 0.1% of sodium chloride, 0.0005% of sodium carbonate, and the balance of water. A preparation method of the disinfection solution comprises the following steps: (1) weighing raw materials for later use; (2) dissolving calcium chloride in water, and filtering to obtain a calcium chloride solution; adding a sodium hypochlorite solution into the calcium chloride solution, and dissolving to obtain a mixed solution; and (3) adding sodium carbonate into the mixed solution while stirring, adding a pH regulator to regulate the pH to 11-12 after the sodium carbonate is dissolved, continuously stirring for 15 minutes, and filtering to obtain the disinfection solution used at the low temperature of -18 DEG C. The disinfection solution provided by the invention can be kept in a liquid state at the low temperature of -18 DEG C, is free of precipitation and crystallization, and can effectively kill harmful germs at the low temperature of -18 DEG C.

Description

Technical field [0001] The present invention relates to the field of disinfectant, more particularly, to a disinfecting solution and a preparation method for a low temperature of -18 ℃. Background technique [0002] Low temperature sterilization technology is a generic term for a class of sterilization method used to process heat intolerance medical devices and items, low-temperature sterilization technology used by the world's major hospitals have glutaraldehyde, acidified water, peracetic acid, ethylene oxide sterilization, hydrogen peroxide low temperature plasma sterilization, low temperature steam formaldehyde sterilization. [0003] Sodium hypochlorite solution is a sodium hypochlorite disinfectant liquid as a main component, a wide range of applications, can kill intestinal bacteria, pyogenic bacteria, pathogenic yeasts, viruses can be inactivated. Commonly used in tableware, fruits, general object surface, disinfecting white fabrics. However readily precipitated crystals ...
