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?

When the leather products are in a humid environment, they are very susceptible to mold damage, which seriously affects the quality of the leather. The growth of mold on the leather will multiply by absorbing the oil and leather fibers in the leather. The lighter ones will cause the leather to lose its luster. Service life.

1. What are the main components of paints and coatings? The main components of 　　 paint include the following five parts: 　　Oil: including dry oil and semi-dry oil, is one of the main film-forming substances. 　　 Resin: Including natural resin and artificial resin, it is also part of the main film-forming material. 　　 Pigments: Including coloring pigments, extender pigments and anti-rust pigments. There are quite a variety of specific types, and they are secondary film-forming substances. 　　 Thinner: Including solvents and diluents, used to dissolve the above substances and adjust the consistency, as an auxiliary film-forming substance. 　　 Accessories: including drier, curing agent, plasticizer, moisture-proof agent. It also belongs to auxiliary film-forming substances.

​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

What is sterilization (sterilazation, sterilant)? Refers to the process of using strong physical and chemical factors to kill or remove all pathogenic and non-pathogenic microorganisms in the external environment, including bacterial spores and fungal spores. It is an absolute concept. The effect is expressed by the sterilization rate, generally ≥99.9999%.

The upstream industries of the coating industry include the manufacturing of chemical raw materials such as resin, solvent, pigment, filler and additives, while the upstream of chemical raw materials such as resin and solvent is the petrochemical industry. The downstream of the coating industry is mainly construction, furniture, automobile, household appliances and other production enterprises and home decoration market.

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.
