The main reasons for the deterioration and smell of metal cutting fluid are anaerobic bacteria and aerobic bacteria. Aerobic bacteria have a characteristic. They must have sufficient oxygen in the process of survival and reproduction.

Generally speaking, a certain preservative can only kill or suppress a certain colony. Therefore, two or more preservatives are usually used in cosmetic formulations to achieve a broad antibacterial spectrum.

Paint preservatives are characterized by high efficiency in killing bacteria, fungi, yeasts, and low dosage; good compatibility with paints, emulsions and other materials; easy to dilute with water, and easy to add paint, coatings and emulsions or In other similar materials; when pH≤9, it is stable.

Stability is the ability of in vitro diagnostic reagents to maintain the consistency of characteristics over time. It is a basic attribute that the reagent must have. It is an important indicator to ensure the effectiveness of the reagent during use, and it is also the responsibility of the manufacturer.

In today’s paper industry, due to the increasing shortage of available resources, the amount of waste paper recycled is increasing, and the recycling of white water systems is also increasing, which will increase the production of pulp; and neutral sizing technology is gradually being promoted and applied. In the alkaline system

Although preservatives and anti-fungal agents sound like an agent used to prevent a certain item from being damaged, they are still different. So today we will talk about the difference between anti-fungal agents and preservatives?

​The stability of in vitro diagnostic reagents is the key to restricting the marketization of products. There have been a number of patents on preservatives for in vitro diagnostic reagents abroad, but the domestic is still in the exploration stage

Preservatives play a decisive role in the washing industry. Nowadays, preservatives can be said to be unique. It is found in various fields. The effect of preservatives is powerful and the coverage area is vast. Because of this, preservatives It is more common in the washing and daily chemical industry. Preservatives are so magical that we say, so what are their specific effects? Today I will introduce to everyone.

Compared with traditional defoamers, paper-making defoamers have better sustainability, and can exert excellent defoaming and anti-foaming effects with a very small amount of addition. In addition, the paper-making defoamer significantly reduces the amount of air inflow and the resulting foam, thereby improving the water discharge of the pulp mat. It can quickly eliminate the foam produced by lignin and other surfactants, and has excellent effects in pulping, pulp washing, papermaking and sizing, and it defoams quickly.

There are many types of antibacterial agents for biological reagents, such as acids, bases and their salts, neutral compounds, mercury compounds, and quaternary amine compounds. Preservatives have a killing effect on microbial propagules, but for spores they can't develop into propagules and gradually die. Different types of preservatives have different mechanisms of action. For example, alcohols can denature pathogenic microorganism proteins; phenylmethylbenzene and parabens can combine with pathogenic microorganism enzyme systems to compete for their coenzymes; cationic surfactants, etc. It is by reducing the surface tension to increase the permeability of the bacterial cell membrane.
