Environmental protection of preservatives

03-02-2023

Environmental protection, the requirements of mildew prevention agent itself less toxic (LD50 value is larger), no irritating smell, will not cause corrosion to the skin, in line with the national environmental requirements of Gallei products. It requires broad-spectrum antimicrobial activity, high efficacy, long-term activity, extensive lethal or inhibitory effect on various molds and bacteria, and the use of low concentration, that is, generally referred to as broad spectrum and high efficiency.


Preservative, usually referred to in the industry is in the tank, that is, in-can, that is, after the product is produced, not before the use of the state, in the tank requires anti-corrosion effect. Antiseptic is a kind of additive in the wet state in the tank, which is mainly aimed at bacteria, killing and inhibiting bacterial growth.


Preservatives: Substances that inhibit the growth and reproduction of microorganisms are called preservatives. Fungicides are substances that destroy and kill microorganisms. Preservatives can kill microbial propagules, but prevent them from developing into propagules and gradually die. Different preservatives have different mechanisms of action. Alcohol, for example, can denature proteins of pathogenic microorganisms; Benzoic acid and paraben can combine with pathogenic microorganism enzyme system, affect and block the metabolic process. Cationic surfactants can reduce the surface tension, increase the permeability of bacterial cell membrane, and make the cell membrane break and dissolve.


We can learn about mildew prevention agents from the different roles of mildew prevention agents and preservatives:


Mildew proof agent, usually refers to paint and other products in the dry film state, that is, film, in order to prevent mold growth need mildew proof effect. Anti-mildew agent is in the dry film state, mainly for mold, kill, inhibit mold growth of an additive.


The role of mildew prevention agent: eliminate mold, prevent the growth of mold. Antimildew agents can harmonize the enzyme system, which affects the metabolism of mold and eventually leads to death. Moreover, by inhibiting the mold aminotransferase system, we can prevent the possibility of mold bacteria surviving through other ways, so as to promote the death of mold. Its main is to increase the degree of promoting phosphoric acid oxidation - reduction system, so that the function of mold cells are seriously damaged, unable to grow normally; It also severely damaged the energy release system of mold, so that they will not cause any harm to the outside world.


Because mold is everywhere, it is easy to stay on some uneven surface, and it begins to grow and multiply when it meets the right temperature and humidity. So when we find something moldy, it's usually an uneven surface, an area where dust accumulates, mold is a microorganism made of protein. These molds grow and multiply particularly quickly in warm, humid conditions, sometimes extending into objects. If mold attaches to clothing, it secretes an enzyme that breaks down cellulose and produces mildew, which significantly reduces the strength of the fabric. In our daily lives, we often use moisture-proof bags to reduce the humidity of items and thus reduce the risk of mildew, and the traditional mildew prevention methods in industry are so weak. So often complain that the product will be moldy.


To protect products from mildew with a mildew inhibitor:


At present, industry often uses mildew prevention agent, it is one of the most direct mildew prevention way, as long as after effective mildew prevention agent treatment, even in the humid environment will not be mildew, whether using spraying or raw materials added or impregnated can achieve good mildew prevention effect. At present, there are a lot of mildew prevention agents on the market, it is difficult to choose the really effective products without careful consideration, the unit price in the screening according to environmental protection, harmless to health, compatibility, and simulation experiment as a reference point.


Scope of application:


Now, a variety of mildew prevention agents are used more and more widely. Bamboo and wood, rattan grass, furniture, leather, luggage, textile, paint, footwear, paint, glue, machinery, electrical equipment, cables, camera lenses, packaging paper, etc., also want to use mildew proof agent
