Polyethylene glycol PEG is a polymer prepared by stepwise addition reaction of ethylene oxide with water or ethylene glycol as raw material. It is a white paraffin-like flake or powder solid, odorless or with weak odor. It is non-toxic, non-irritating, has good water solubility, and has good compati

The washing effect of surfactants is the basic characteristic of the most practical use of surfactants. It involves the daily life of thousands of families. And in all walks of life and various industrial production has also been more and more applied.Dry cleaning is a method of washing in organic s

Industrial cleaning technology can be divided into fine chemical cleaning, physical cleaning and biological cleaning according to the principle of cleaning. Among them, fine chemical cleaning technology has the longest history, the most kinds and the most widely used. Chemical cleaning according to

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

A team led by researchers at Virginia Tech University has developed the world's first soap made from plastic, according to a report in the latest issue of Science magazine. The new method could upgrade plastics into a high-value chemical called a surfactant.The wax produced by waste polyethylene and

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

As we all know, emulsifiers are widely used, and it is no exception in the field of pesticides. Today, Haian Petrochemical will take you to understand the application and prospect of emulsifiers in the field of pesticides:Emulsifier is one of the essential components in the preparation of pesticide

1. Random polymeric surfactantThis kind of surfactant is a polymer surfactant with a three-dimensional network structure formed by polymerization of polyalkylene diols, polyols and fatty or aromatic polycarboxylic acids and their anhydrides. For example Atlox49.4(HLB=6), the hydrophilic action is pr

Principle of action: When the affinity of the levelling agent to the dye is greater than the affinity of the dye to the fiber, before the dye is adsorbed by the fiber, the levelling agent first pulls the dye, and then combines to form a stable aggregate, and the dye is separated from the levelling a

After the defoamer manufacturer produces the defoamer for coating, in order to ensure the quality of the product, it is necessary to check the performance. The following six test methods can be used:1, the measuring cylinder method: add an appropriate amount of low-viscosity paint in the measuring c
