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

Penetrants are known to play a role in osmosis, a substance that can be arranged in a directional manner on the surface of a solution to reduce surface tension. Simply put, it is a chemical that can help the substance that needs to be penetrated to penetrate into the substance that is penetrated, m

The broad concept of penetrant refers to a class of chemicals that can help the substance that needs to be permeated to penetrate the substance that needs to be permeated, and the industry generally uses surfactants (which can be anionic or non-ionic) or organic or inorganic solvents. Penetrants are

In the middle of the 20th century, with the rapid development of industrial production and the rapid promotion and application of polymer materials, on the one hand, some high resistivity polymer materials such as plastic, rubber and other products are widely used and the high-speed modern productio

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

Chemical composition: Polyethylene glycol 400 monostearateType: Non-ionicAppearance: yellowish to milky white solidHLB value: 11Content: >99%Second, performance and use1, soluble with oil and organic solvents, compatible with most surfactants, stable in a wide PH range, with excellent emulsification

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

Surfactant is one of the materials in the field of metal surface treatment technology, and it is also one of the indispensable components of most electroplating additives. In the entire process of electroplating, such as chemical degreasing before plating treatment, pickling rust removal, electrolyt

Polyethylene glycol 200, also known as PEG200, is a water-soluble, odorless, tasteless polymer that has a wide range of applications in the daily chemical industry. The compound has a molecular weight of about 200g/mol and is commonly used as a moisturizer, solvent, and viscosity agent in a variety

In the use of pesticides, only a few cases are the direct use of the original drug, and most of the cases are mixed with other additives and solvents to improve its use value and reduce the cost of use. Surfactant is a kind of additives that can give greater play to the value of pesticides and reduc
