What is the relationship between HLB value, solubility and temperature of surfactants

The HLB value of surfactants is related to their applications: surfactant molecules are amphiphilic molecules with both hydrophilic and lipophilic groups, and different types of surfactants have different hydrophilic and lipophilic groups, and their hydrophilicity and lipophilicity are different. The hydrophilicity of surfactants can be measured by the hydrophilic and lipophile balance values (HLB), which …

Water-based defoamer dry goods interpretation

In industrial production, many harmful foams are often generated, which, if not treated in time, can cause capacity limitations, waste of raw materials, longer production cycles, inaccurate measurement, environmental impact and other problems. In order to deal with the situation, in addition to the use of physical defoaming method, more use to add defoamer to …

Why is there such a high level of interest in succinic acid?

Why is there so much attention on succinic acid? On the one hand, it is based on the development opportunities of the whole industry chain brought by the development of biodegradable plastic industry, and on the other hand, it is the downstream industry chain extension opportunities of maleic anhydride products. In this article, a certain …

How to effectively deal with the surface residue of metal working fluid

One of the main functions of metalworking fluids is to provide inter-process rust resistance to the part, which is accomplished through the rust-proof film left on the metal surface. Therefore, the discussion here is not whether the metalworking fluid leaves a residue, but whether the residue is purposefully left behind. The residue of metalworking fluid …

Downstream applications of silicone surfactants

Silicone surfactants are a very important branch of surfactants, which possess the temperature and weather resistance, dielectric properties and biocompatibility of silicone products, but also exhibit characteristics such as low surface tension and good wettability. One end of silicone surface activity is silicone oil and the other end is polyether. The two are bridged by …
