Example Embodiment

[0030] Example 1. Make corn stalk powder into 50-mesh powder, take 30 parts of corn stalk powder, 2 parts of white oil, and 1 part of Taiqing green in a mixer and mix them well. That is, take dibromoisocyanuric acid for mixed bran, 40 parts of mixed bran and 10 parts, mix well and put them in the same bag as agent A. Powder into 6 parts of 100 mesh potassium nitrate and 10 parts of ammonium chloride. 1 part of ammonium bicarbonate and 23 parts of mixed bran are packed into a bag as agent B. Put A agent and B agent in the same bag, which is the smoke agent of this patent.

Example Embodiment

[0031] Example 2 Get 30 parts of flour (50 mesh) and 5 parts of paraffin wax, 2 parts of solid green and fully mix in mixer to make mixed bran. Take 20 parts of sodium trichloroisocyanurate, mix 30 parts of bran, mix them fully and put them in the same bag as agent A. Powder into 100 mesh 20 parts of potassium chlorate, 23 parts of ammonium chloride, 7 parts of mixed bran, mix well, put them in the same bag as agent B. Packing agent A and agent B in the same bag is the smoke agent of this patent.

Example Embodiment

[0032] Example 3 sawn wood powder into more than 50 orders, get 21 parts of sawn wood, 2 parts of malachite green, 5 parts of lubricating oil, mix evenly, and make mixed bran. Take 28 parts of mixed bran and 38 parts of dichloroisocyanuric acid above 100 mesh and mix and pack it as agent A. 20 parts of potassium nitrate above 100 mesh and 30 parts of ammonium carbonate are evenly mixed and packaged as agent B, and agents A and B are packed in the same bag to obtain the smoke agent of this patent.

Abstract

The smoke agent for sterilizing refrigeration house and processing workshop consists of disinfectant, oxidant, inflammable carrier, fire retardant, moisture preventing agent and coloring agent. The disinfectant is one or several kinds of trichloro isocyanuric acid and its sodium or potassium salt, dichloro isocyanuric acid and its sodium or potassium salt, tribromo isocyanuric acid and its sodium or potassium salt and dibromo isocyanuric acid and its sodium or potassium salt; the oxidant is one or several kinds of potassium permanganate, potassium chlorite, potassium nitrate and potassium nitrite; the inflammable carrier is flour, rice straw and corn stalk; the fire retardant is one or several kinds of ammonium chloride, sodium carbonate and sodium bicarbonate; the moisture preventing agent is white oil and the coloring agent phthalocyanine green. The present invention has high disinfecting effect, no harm to human body and less corrosion to metal, less production investment and simple production process.

Description

technical field [0001] The invention belongs to a disinfectant for cold storage and processing workshops, in particular to a smoke agent for disinfection in cold storage and processing workshops and a preparation method thereof. Background technique [0002] At present, there are mainly three kinds of disinfectants used in cold storage and processing workshops: sulfur dioxide, bleaching powder, and formaldehyde. Sulfur dioxide has an inhibitory effect on some fungi but has no effect on bacteria and yeast, and its biggest disadvantage is that it is highly corrosive to metals. Therefore, this disinfectant should not be used in disinfection places with metal. Especially the cold storage used to store agricultural products, there are a lot of metal facilities and utensils in the cold storage, and the metal facilities of the cold storage will be destroyed if sulfur dioxide is used twice in a row. Bleach powder needs to be formulated into a solution and then sprayed on the storer...
