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

The addition of surfactants greatly reduces the surface tension of the solution, enhances the wetting, distribution and adhesion of the agent on the body surface of the plant or pest, increases the retention amount of the pesticide on the plant surface, extends the retention time and improves the pe

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

Softener is a kind of chemical substance that can change the static and dynamic friction coefficient of fiber. When the coefficient of static friction is changed, it feels smooth and easy to move on the fiber or fabric; When the coefficient of dynamic friction is changed, the fine structure between

Defoamer, also known as anti-foam agent, will produce many harmful foams in the process of industrial production, and it is necessary to add defoamer. It is widely used to remove harmful foam produced in the production process of latex, textile sizing, food fermentation, biomedicine, coating, petroc

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

one Spray cleaning The method of using a cleaning agent to achieve low or no bubbles1. Add defoamer: silane defoamer, polyether defoamer and low molecular alcohol are commonly used.2. Choose a suitable surfactant.two There are three main methods for surfactant selection:1. Commonly sprayed low-foam

When the air enters the liquid, because it is insoluble in water, it will be separated into many bubbles by the liquid when there is an external force, forming an uneven system. When the air enters the liquid to form a foam, the contact area between the gas and the liquid increases, and the free ene
