Abstract

The invention discloses a preparation method for a deodorization sterilization sheet used for sterilizing infectious medical waste. The preparation method comprises the following operation steps: (1)preparing sodium aluminate solution, then, regulating the pH (Potential of Hydrogen) of the solution, heating mixed liquid, carrying out thermal insulation reaction, cooling to room temperature, carrying out centrifugation to obtain sediments, and preparing a water insoluble carrier; (2) after polyethylene glycol 6000 is heated and fused, adding sodium lignin sulfonate, sodium bicarbonate and N-octyl diamine ethyl glycine hydrochloride into the polyethylene glycol 6000, cooling to room temperature, and smashing to obtain a water-soluble carrier; (3) evenly mixing the water insoluble carrier, the water-soluble carrier, citric acid and sodium dichloro cyanurate, slowly adding absolute ethyl alcohol and 4-dodecalactone into the mixture to be evenly stirred, adding into a granulator to be granulated and dried, and pressing to obtain the deodorization sterilization sheet. The deodorization sterilization sheet prepared with the preparation method has the advantages of obvious sterilization effect, no odorous pungent smell, and odorous smell in the infectious medical waste can be effectively prevented from emitting.

Description

technical field [0001] The invention belongs to the technical field of medical waste treatment, and in particular relates to a method for preparing a deodorizing and disinfecting tablet used for disinfecting infectious medical waste. Background technique [0002] Medical waste refers to infectious, toxic and other hazardous waste produced by medical and health institutions and medical scientific research units in the process of diagnosis and treatment, testing, testing, etc., as well as excreta and garbage produced in the life process of patients. Infectious medical waste refers to medical waste that carries pathogenic microorganisms or their related genes, which can cause the spread of infectious diseases or cause biological safety hazards. Such as items contaminated by blood, body fluids or excrement of patients or sick animals, such as cotton swabs, cotton balls, gauze; contaminated disposable medical and sanitary products, such as infusion sets, disposable syringes, disp...
