Problems solved by technology

CN101167478 discloses a novel fumigant integrating disinfection, insecticide and rodent control, which is composed of 40-60% by weight of sulfuryl fluoride and 40-60% of carbon dioxide. Due to the certain toxicity of sulfuryl fluoride, its The dosage is still too large, and sulfuryl fluoride is a single toxic component, so it generally requires a higher dosage and a longer fumigation time to treat insect eggs

Abstract

The invention discloses an insecticidal fumigant for a cigarette making machine set and a fumigating and killing method, belonging to the field of pest control of cigarette production equipment. The insecticidal fumigant for the cigarette making machine set is prepared from the following components in percentage by weight: 19 to 36% of sulfuryl fluoride, 54 to 76% of carbon dioxide and 5 to 10% ofS-methoprene. A preparation method of the insecticidal fumigant comprises the step of sequentially filling a pressure-resistant container with the sulfuryl fluoride, the carbon dioxide and the S-methoprene according to a sequence from a low vapor pressure from to a high vapor pressure. The fumigating and killing method comprises the following steps: sealing a cigarette making machine set, injecting the insecticidal fumigant into the cigarette making machine set, conducting fumigating and killing for 36-48 hours at a temperature of 15-35 DEG C, and recovering the insecticidal fumigant after the fumigating and killing are finished. The fumigant disclosed by the invention is low in toxicity, small in adsorption capacity, fast in analysis, strong in permeability and high in safety, can be used for effectively killing hidden insects and worm eggs in the unit, and has the advantages of thorough insect killing, short fumigating and killing period and no adverse effect on a cigarette unit.

Description

technical field [0001] The invention belongs to the field of pest control of cigarette production equipment, and in particular relates to the technical field of control of hidden pests in a cigarette unit, in particular to an insecticidal fumigant and a fumigating method for a cigarette unit. Background technique [0002] The cigarette making unit is mainly used for processing flavored and fed shredded tobacco, which includes crimpers, PT series crimpers, packaging units and other equipment. The equipment structure is complex, precise and expensive. Shredded tobacco and smoke foam during cigarette production are easy to scatter in the gaps of various protective covers, sound insulation cotton, gas circuit and electric circuit of the unit equipment. The brand image of cigarette products has caused heavy losses to enterprises. [0003] At present, the pests of the cigarette unit are mainly treated by chemical agents, sanitation and air conditioning. The chemical agent treatme...
