Why Does DBNPA Can Be Used As Wood Mold Inhibitor?
Principle of wood mold inhibitor?
1. Inhibit the growth and reproduction of mold, reduce the growth rate of mold number.
2. Kill the individual mold and reduce the absolute number of mold in the system.
The former is called antibacterial effect. It is to prevent the growth of individual mold under the effect of wood mold inhibitor. That can

The latter is called bactericidal effect. This is the process of death due to the interaction of wood fungicides and mould proteins, which leads to the failure of the individual microorganism to maintain normal physiological activities.
The above two effects are relative. The difference is often related to the concentration of the agent. When the concentration was high, the fungicide showed killing effect on microorganisms. When the concentration was low, the fungicide showed inhibitory effect on microorganisms.
Wood mold inhibitor can contact and adsorb with the outer membrane of mold cells. Then the fungicide enters into the protoplast through the cell membrane and acts on some part of the microbial cell.It can inhibit or change the biochemical reaction and metabolic activity of mold. Finally, it can inhibit the growth and reproduction of microorganisms on the surface of wood. And even kill the microorganisms.
Wood mold inhibitor act on various metabolic mechanisms essential for maintaining the life of microbial cells. Such as cell wall synthesis, cell membrane function, protein synthesis, nucleic acid synthesis, energy metabolism and so on. Or act on various enzymes related to these metabolic mechanisms.
What are the product features of DBNPA mold inhibitors?
1. High efficiency and broad spectrum.
DBNPA has excellent bactericidal effect.It can kill or inhibit many kinds of mold.In wood and its products, a small amount of chemicals can kill mold or inhibit its growth and reproduction.The fungicide not only has the function to the mold, but also has the effect to other kinds of microorganism.九歌电影最新章节目录_九歌电影最新章节 九歌电影最新章节目录_九歌电影最新章节 ,2020中国好声音第一期最新章节列表_2020中国好声音第一期 2020中国好声音第一期最新章节列表_2020中国好声音第一期
2. Low toxicity and long-term effect.
DBNPA has high safety. It has a long validity period and does not pollute the environment and water quality. Generally speaking, LD50 (half lethal dose) of acute oral administration should be more than 500 mg / kg. No irritation to skin, mucous membrane and eyes. The toxicity to experimental animals should also meet the hygienic requirements. It is required that the agent will not decompose and fail within half a year or more.
(3) Good physical and chemical stability.
DBNPA has strong stability to light, heat, acid, alkali, vibration and so on. It has good solubility to the related solvents. It is odorless, non corrosive and low volatile. It has good compatibility with wood and its products. Generally, it does not affect the material and physical processing properties of wood.
(4) The price is low and the construction is convenient.
Our company produces DBNPA, isothiazolinone and other series products. The product does not contain arsenic, chromium and other persistent organic pollutants. It is harmless to human body and does not pollute the environment. The wood is endowed with high-efficiency preservative, insect and termite resistant properties. It is widely used in poles, marine materials, sleepers, cooling tower components, piles, fences, terraces, outdoor wood / bamboo products and building anti-corrosion function.
