Coating classification: alkynol multifunctional surfactant

Core tip: Product Introduction: the so-called surfactant is such a substance, which is active on the surface (Interface) of the system, and has a very high ability or efficiency to reduce the surface (Interface) tension of the system In the solution and the interface, it can combine itself to form a molecular ordered combination, which plays an important role in various important processes, such as wetting, dispersion and so on As we all know, traditional surfactants only have one hydrophilic group and one lipophilic group, while alkynol multifunctional surfactants have two hydrophilic groups and two lipophilic groups, which are symmetrically connected, Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: Product Introduction: the so-called surfactant is such a material, which is active on the surface (Interface) of the system, with a very high ability or efficiency to reduce the surface (Interface) tension of the system In the solution and the interface, it can combine itself to form a molecular ordered combination, which plays an important role in various important processes, such as wetting, dispersion and so on As we all know, the traditional surfactants have only one hydrophilic group and one lipophilic group, while alkynol multifunctional surfactants have two hydrophilic groups and two lipophilic groups, which are symmetrically connected by two amphiphilic groups, and their interfacial activity is much higher than the traditional surfactants Surface tension is an expression of molecular force It occurs in the boundary part when liquid and gas contact The addition of surfactant will inevitably lead to molecular orientation, which makes the surface tension of liquid drop sharply The nonpolar part of the molecule stays in the direction of the liquid surface toward the air, and the polar part stays in the liquid phase The surface tension is directly related to the wettability of the liquid to a certain substrate The lower the surface tension, the better the wetting effect, otherwise the worse the wetting effect The wettability can also be achieved by wetting contact angle θ reaction The contact angle θ = 0 indicates complete wetting; the contact angle 090 indicates non wetting; the contact angle θ = 180 indicates complete non wetting The existence of foam seriously affects the appearance of coating, which often causes defects such as shrinkage cavity, pinholes, defects, fish eyes and so on Therefore, the bubble problem has not only affected the protective effect of the film, but also greatly affected the decorative effect of the coating Generally, traditional surfactants are also good at foaming Factors affecting bubble stability: surface tension, charge stability, surface viscosity, steric hindrance, self repairing of surface tension Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
