The application value of fungicides in industrial field
Microorganisms are widely distributed in nature, and traces of microorganisms can be found in the air, soil, rivers, oceans and natural objects. In general, the environment contains 1-10,000 microorganisms per liter of air, 10,000-10 (10) microorganisms per gram of soil, and 1-10,000 microorganisms per gram of water; There are 10(7)-10(10) bacteria, 10(5)-10(7) actinomycetes and 10(3)-10(5) molds per gram of fertile soil. These are the main sources of microbial pollution in the production environment, industrial materials and industrial products.
Many industrial materials and products, especially those that are organic or contain organic materials, are themselves readily available sources of nutrients for microorganisms (such as food, store materials, wood, paper, textiles, leather, cosmetics, coatings, and certain plastics, etc.), and once environmental conditions are suitable, microorganisms will grow and multiply rapidly. Damage the material structure of the material, so that it deteriorates and deteriorates, resulting in economic losses. Some inert materials and their products (such as metals, glass, electronic devices, optical instruments, etc.) cannot be used by microbiota themselves, but they are also subject to microbial hazards. Because some moldy microorganisms can reproduce and grow under extremely poor nutrient conditions, even micronutrients (including carbon compounds, nitrogen compounds, minerals, etc.) left by material residues, air or fingermark stains are enough to support the growth of these microorganisms. The secretions in the growth process (such as acids, alkalis, oxidizing substances, etc.) can cause corrosion and damage to industrial materials and products.
In industrial production, there are a variety of measures to prevent and control microbial hazards, and in all the prevention and control measures, the application of fungicides is undoubtedly a method with high effectiveness, fast effect, easy operation and low cost. This is because in actual use:
(1) The selected fungicide must be those varieties with strong pertinence and high virulence to the target microorganisms, so that the efficacy is fully guaranteed;
(2) Through direct contact between bactericides and bacteria, the target microorganisms can be poisoned at a fast speed;
(3) A variety of dosage forms of fungicides are easily dispersed into various materials, including gas, liquid or solid state, so that the relevant environment, materials or products are effectively protected;
Compared with freezing, high temperature, high pressure, drying, deoxygenation, radiation, filtration and other microbial control methods, the application of fungicides does not require special equipment, energy saving, time saving and labor saving, and economic benefits are obvious.
It is generally believed that the purpose of the use of industrial fungicides is to maintain the quality of products, its essence is to extend the shelf life and service life of industrial materials and products, traditional preservatives, mildewproof agents, preservatives and water treatment agents are born for this purpose. Industrial disinfectants through the treatment of air, equipment, appliances, packaging, so that the production environment to meet certain health requirements, in the final analysis, is to make the quality of the product produced in the storage period and the use of the period to be guaranteed. In recent years, industrial antimicrobials have shown some "functional" characteristics, adding such antimicrobials to fabrics (such as underwear), ceramics (such as sanitary ware), plastics (such as air conditioning filters) and other products, not to prevent microbial damage, but to give them the function of killing human pathogenic microorganisms.
It can be seen that the application of fungicides in the industrial field can not be underestimated in creating a suitable production environment, the protection and utilization of resources, the quality assurance of products, and even technology development and market expansion.
