The function of surfactants1. Wetting effectWhen a solid is in contact with a liquid, the original solid/gas and liquid/gas interfaces disappear and a new solid/liquid interface is formed, a process called wetting. For example, textile fiber is a porous substance with a huge surface, when the soluti

1. CosmeticsSurfactants are widely used in various cosmetics as emulsifiers, penetrants, detergents, softeners, wetting agents, fungicides, dispersants, solubilizers, antistatic agents, hair dyes and so on. Non-ionic surfactants are most commonly used in cosmetics because they are non-irritating and

The molecules of surfactants are composed of hydrophobic and hydrophilic groups, which can form ordered assembly micelles, reverse micelles, vesicles and so on in solution, and ordered assembly can be used as a "microreactor" to prepare nanoparticles. The surfactant can make the carrier form a direc

Penetrant JFC use:Used for sizing, desizing, boiling, bleaching, carbonization and chlorination and other processes, can also be used as dyeing bath and finishing bath penetrant, as well as leather coating penetrant.The leather industry is mainly used as a water immersion agent, which can significan

Textile printing and dyeing products can be seen everywhere in daily life, there will be foam during textile printing and dyeing, each manufacturer will add a variety of surfactants during printing and dyeing to assist processing, different procedures through stirring and mechanical shaking will be

Technical indicators of several different specifications:Specifications/appearance (25 ℃)/hydroxyl value (mgKOH/g)/saponification value (mgKOH/g)/acid value (mgKOH/g)/water portion (%)/HLB value, melting point (℃)Span 20:Amber viscous liquid /330 ~ 360/160 ~ 175/≤ 8/≤ 1.5/8.6/ liquid (25 ℃)Span 40:Y

Polycarboxylic acid superplasticizer has a special comb structure, through the static effect and steric hindrance effect to promote the dispersion of cement particles, improve the workability of concrete mix, effectively reduce water consumption, improve the physical properties of concrete, includin

Flotation deinking is to dilute the concentration of purified waste pulp to 0.8% ~ 1.2%, into the flotation machine, add deinking agent and a small amount of foaming agent to the slurry, at room temperature, air is pumped into the flotation separation, printing ink, pigment and other impurities are

Tween 80 is a non-ionic surfactant with significant resistance to electrolyte and strong hydrophilicity. It is an excellent O/W emulsifier. The high concentration of electrolyte and the change of pH value have little influence on its emulsifying ability. It has a good emulsification effect on vegeta
