surfactant is that very few can significantly change the material surface and interface properties of substances. The molecular structure characteristics also include two parts, one is a long nonpolar hydrogen, known as the hydrophobic group; The other one is a short polarity based, referred to as the hydrophilic group.
surfactant surface tension, surface adsorption, wetting, emulsification, performance such as dispersive, in suspension, and the above two basic features have a direct or indirect relationship.
the types of surfactants. Surface active agent according to whether can dissolve in water after ionization, it can be divided into two categories: ionic and nonionic. And ionic type can be divided into anionic, cationic and amphoteric ionic. The specific varieties are: common surfactants sorbitan oleate, ethylene glycol fatty acid ester, propylene glycol fatty acid ester, half as many sorbitan oleate and so on. Other than alkyl aryl sulfonate anionic surfactant, the rest is for nonionic surfactant. In addition, apart from the above small molecular surfactants, and polymeric surfactants.
the selection of surfactant. Different additives, choose different surfactants respectively; Corresponding to different resin, choice of different surfactants; In addition, as far as possible with higher surface tension of surfactant.
the polymer compatibilizer and compatilizer of additives. Polymer treating agent can solve the small molecule agents make plastic products the shortcoming of performance variation. In acid and alkaline solution to deal with additives, the additive functional groups on the surface of the change, or mediate the surface acid, alkaline, to achieve the goal of compatibility with resin.
the mechanism of plasma processing additive is: all the above activation of plasma particles and ultraviolet radiation can lead to produce a variety of chemical additives on the surface of change, to generate a variety of oxygen-containing groups, and from the greatly improve its surface hydrophobicity, increase the compatibility with the resin. Plasma processing is a new technology, it has low processing temperature and time is short, the characteristics of high efficiency.
the mechanism of the surfactant. Owing to surfactant the asymmetric amphiphilic molecular structure characteristics, therefore has two basic characteristics, it is very easy to the orientation arrangement on the material surface or two phase interface, so that the surface or interface properties changed significantly; Second, surfactant solubility in the solution, i. e. , according to the molecular dispersion state of concentration is low, in the presence of commonly used most in micelle concentrations exist.
plasma is a kind of ionized gas, it is the state of aggregation of matter energy is higher, also known as the fourth state of an object. Plasma also contains atoms or molecules of electronics, dissociation free radicals, in the excited state, or has not been excited neutral atoms or molecules and dissociation process generated by ultraviolet light.
