Metalworking fluid is a fertile breeding ground for microbial growth. Many workers use the processing fluid when they think that they do not need to add industrial preservatives. After adding, they will destroy the function in the liquid.

1,2-Benzoisothiazolin-3-one (BIT) This fungicide is one of the new generation of industrial fungicides in the world today. Products were introduced in the 1970s. In the early 1980s, Imperial Chemical Industries invested £5.5 million to develop a continuous production process and achieved great success in synthetic emulsions, waterborne coatings, adhesives, paper, metal cutting fluids, technical oils, and oilfields.

Waterborne pigments are very sensitive to microbial attack. In general, all organic pigments can be used by a variety of bacteria to become a source of carbon and nitrogen for bacteria. In all pigment tests, yellow pigments are most susceptible to microbial degradation due to organic components.

Bacteria are a class of prokaryotic microorganisms. They are a kind of prokaryotic organism with short shape, simple structure and multi-divisional reproduction. It is the most widely distributed organism in the natural world and the main body of natural material circulation. By Bacterial reproduction

The application of paint in our daily lives is very common, bringing aesthetics and protecting the outer layer. In the paint, a potion is used, which is a paint mold inhibitor. Using it, it can achieve an unparalleled anti-mildew effect.

Bronopol is a class of high-efficiency, broad-spectrum preservatives with the following distinct advantages: Bronopol at a concentration of ppm can effectively kill bacteria

There are many types of microbes in jet fuel, which can be divided into three categories.

There are a large number of various microorganisms in the metal working fluid

Mainly refers to physical blending, which is the easiest and most common method. Regardless of the form of the mold-proof fungicide (solid, powder, liquid, etc.), it is only a physical mixture when added to the paint. Therefore, the efficacy of the mold-proof fungicide is not only related to its own efficacy, It is also closely related to particle size, degree of dispersion, and the like.

Modern papermaking mostly uses vegetable fiber cooking and pulping or pulp paper as the main raw material pulping process. Mortar is mainly caused by microorganisms, including filamentous bacteria from water, algae and mold in the air, and a large number of bacteria in waste paper. At the same time, a large number of chemical additives added in paper production, such as: Glues, starches, dyes and fillers are rich in nutrients, which provide abundant food for these microorganisms. In addition, the papermaking process can provide temperature and environment suitable for microbial reproduction, and microorganisms can grow and multiply once they are intervened. When microorganisms grow, they often adhere to the surface of the object (pipes, pool walls, etc. of the slurry process) to form biofilms
