What points do you need to pay attention to when buying mildew prevention agents? Problem one, the initial waterproof performance of anti-mildew agent is poor

Wall mildew protection agents are very small molecules, they can penetrate deeply when used on the appropriate substrate surface, they react with the substrate and itself, and obtain durability, after curing, water vapor may pass through, and liquid water cannot enter the substrate

Preservative manufacturers tell you that with the increase of modern people's awareness of health and healthy diet, preservatives have become drugs in food, and people have reached the degree of "talking about preservatives color change" when they buy food in supermarkets. In fact, preservatives are necessary additives in many foods and are essential ingredients for preserving food, and normal doses of preservatives will not cause any harm to the human body.

How to use fungicide in metal cutting fluid? Roughing steel parts usually set aside a processing allowance, the production of difficult processing raw materials and rare metal raw materials, roughness precision index value is not high

Bactericidal preservatives are mainly used to ensure that materials do not deteriorate during use by killing bacteria or making them lose their ability to grow and reproduce. Bactericidal preservatives can denature proteins in microorganism

Application and types of preservatives: Bacteria are everywhere, such as dust, soil, sweat, air. As long as it meets the right temperature and humidity, it begins to grow and multiply from uneven places. Therefore, the first place to grow mold is generally at the interface, where stitches are made, which is a great harm to the storage and transportation of raw materials and their products. The main function of preservatives is to no longer grow mildew even in the harsh humid environment. Preservatives series of mildew prevention principle: destroy the bacterial cell wall and the enzymes in the cell, so that the enzyme proteins can not participate in the catalytic action, effectively prevent the growth and reproduction of bacteria, preservatives mainly include the following:

Metal cutting fluid deterioration odor main cause from anaerobic bacteria and oxygen consumption bacteria, oxygen consumption bacteria have a characteristic, in the process of survival and reproduction must have sufficient oxygen, in the absence of oxygen will automatically disappear or unable to reproduce;

IPBC is a kind of mildew killing compound, added to the pigment, can prevent the growth of mold in storage and make color changes, improve the shelf life of the pigment.

What is antibacterial paint? Antibacterial coatings come in the form of solvent-based, water-based or powder coatings. Can make the product surface coating with antibacterial function, inhibit the reproduction of bacteria and fungi. Antibacterial coatings enhance the surface protection of products
