Factors affecting carbone preservative

Alkylammonium chloride (AAC) is the general name of the third and fourth ammonium salts. It is effective to A wide range of organisms, has little impact on the environment, and has good natural degradability. The appearance and processing properties of treated wood are similar to those of untreated wood, and it has great application potential.

What are the main ingredients of preservatives? Usually when we eat snacks, we will find that there is a small bag in each bag. In fact, it is a preservative. What is its main function?

Bactericidal algaecide is a combination of highly effective surfactants and highly effective biocides. It combines the slime stripping effect of highly effective surfactants with the outstanding bactericidal and algaecide ability of highly effective biocides

Dalian Tianwei bactericidal, antiseptic and mildew prevention agent is developed by our company's proprietary technology.

According to the degree of their inhibition of microbial growth, antibacterial agents are divided into sterilization agent, disinfectant and antibacterial agent.

Wall anti-mildew agents are very small molecules, they can be deeply penetrated when used on the surface of the appropriate substrate, they react with the substrate and itself, obtain durability, curing, water vapor may pass through, liquid water can not enter the substrate. Wallpaper mildew is colorless transparent neutral waterproof agent (PH ≌8), will not react with the substrate, it can penetrate into the substrate interior to more than 3 mm, after curing, liquid water can not pass through, air can pass through, effectively prevent the wall moisture infiltration

The temperature, pH and nutrient composition of the circulating water are all conducive to the propagation of microorganisms, and sufficient sunlight on the cooling tower is an ideal place for algae to grow. The direct flow system has no air
