Peregal O-25 is a chemical product used in the printing and dyeing industry, metal processing, glass fiber industry, and agriculture.1, in the printing and dyeing industry, as a levelling agent, diffusion agent, stripping agent, the general dosage of 0.2-1g/L, the effect is significant, increase the

surfactant refers to a substance with fixed hydrophilic and oilophilic groups, which can be oriented on the surface of the solution and reduce the surface tension significantly.The molecular structure of surfactants is amphiphilic: one end is a hydrophilic group, the other end is a hydrophobic group

I. Levelling agent for high temperature dyeingIn the process of high temperature and high pressure dyeing with disperse dyes, the uneven dyeing is often caused by the poor dispersibility, evenness, transference and improper control of temperature rise rate. In particular, the linear density of fine

Nonionic surfactants have many uses. The drilling fluid used in drilling needs to add defoamer, emulsifier, fungicide, viscosifier, diluent dispersant, dewatering agent, lubricant, anti-corrosion agent, etc., which are closely related to non-ionic surfactants.Non-ionic surfactants are used in oil di

1. Causes of surfactant foam formationWhen a surfactant is mixed with water, the hydrophilic end dissolves in the water, and the hydrophobic end detaches from the water and gathers at the surface. In surface surfactants, hydrophobic groups will leave the water surface and enter the air, and hydrophi

HLB is the abbreviation of hydrophile lipophile balance, which indicates the hydrophilic and lipophile balance value of the surfactant, that is, the HLB value of the surfactant. High HLB value indicates strong hydrophilicity and weak lipophilicity. On the contrary, oleophilicity is strong and hydrop

The smaller the surface tension of the lubricant, the better its spreading performance. Under normal circumstances, the surface tension of pure water is high, up to 72.75×10-5N/cm, so it is necessary to reduce its surface tension in order to be suitable for wetting printing plates. At present, the b
