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

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

The frictional properties of fibers can determine the ease of sliding between fibers, so it plays an important role in the mechanical processing of fibers such as carding, spinning or winding. Synthetic fibers such as amide fiber, polyester fiber, acrylonitrile fiber and other polymer compounds have

Anionic surfactants, that is, ionic surfactants that can ionize into anions when dissolved in water, are called anionic surfactants. It is also divided into two categories: first, salt anionic surfactants, such as carboxylate type (R-COONa) and sulfonate type (R-SO3Na) active agents, which are compo

Periga is a natural admixture of fatty alcohols and ethylene oxide. Structural formula: RO (CH2CH2O) nH.Fatty alcohol polyoxyethylene ether, levelling agent O, also known as flat plus O, is a non-ionic surfactant, the appearance of milky white or beige paste, high molecular weight, solid (can be mad

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
