The most important difference between non-stick cookware and ordinary cookware is that the surface is coated with a layer of non-stick paint, and the Teflon non-stick cookware commonly used on the market is to coat the main raw material of fluorinated resin such as polytetrafluoroethylene coating on the metal surface such as aluminum, copper or iron, and through sintering. Properties of NI-PTFE co...
Classification of surfactant applications in coatings: According to the role of the classification, the coating industry used surfactants can be divided into the following categories: emulsifier, pigment surface treatment agent, pigment wetting dispersant, defoamer, levelling agent, anti-mold, fungicide, antistatic agent, brightening agent, slippery agent and so on. Application of surfac...
In the use of pesticides, only a few cases are the direct use of the original drug, and most of the cases are mixed with other additives and solvents to improve its use value and reduce the cost of use. Surfactant is a kind of additives that can give greater play to the value of pesticides and reduce the cost of pesticides. It plays the role of emulsification, foaming/defoaming, dispersi...
Thermal spray Teflon can not only reduce product costs and improve production efficiency, but also can be used to directly solve problems on the product to improve product quality and increase sales. After being sprayed with Teflon, it has the following characteristics: 1.Slippability: PTFE spray film has a low coefficient of friction. When the load slides, the friction coefficient changes, b...
Many people think that the temperature of the primer baking (dry) of Teflon paint is not important, just bake it, in fact, this is a misunderstanding. If you usually encounter the following situations, please carefully bake the primer. For the primer coating of Teflon paint, we recommend a temperature of 150 ° C, after the workpiece reaches 150 ° C, bake for 5-10 minutes. I. If the temperature of ...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
The hardness and softness of the water-based acrylic resin can be adjusted according to specific needs, but it is usually biased towards the harder side. First, the characteristics and application of water-based acrylic resin Water-based acrylic resin is an environmentally friendly water-based resin, with non-toxic, easy to clean, dry fast and other characteristics, widely used in furniture, packa...
The final state of waterborne polyurethane is a solid film. During the process from emulsion to solid film, accompanied by the evaporation of water and the concentration of water dispersion, the latex particles are close to each other. Before the solid content reaches 74%, the dispersion particles can move in the continuous phase of water. Under the influence of water/air interfacial tension, the ...
Due to the hydrophobic properties of waterborne polyurethane resin, it is difficult to dissolve in water or disperse uniformly, and the high reactivity of isocyanate groups to water, the direct synthesis of waterborne polyurethane faces many challenges. Therefore, to achieve the preparation of waterborne polyurethane, the primary strategy is to cleverly integrate hydrophilic functional groups (suc...
The viscosity of waterborne polyurethane emulsion has different distribution range, and the viscosity of waterborne polyurethane emulsion has different requirements when applied in different fields. In addition to adjusting the viscosity by adding thickening agents, it can also affect the viscosity of waterborne polyurethane emulsion from the molecular structure, including the content of hydrophil...
Water based polyurethane emulsion has soft properties, so that it has good adhesion when attached to the surface of the object; At the same time, it can maintain a certain strength and does not crack. It is especially suitable for articles in high temperature, humid and chemically corrosive environment. This substance also has superior wear resistance and film smoothness, so it can form a uniform ...
Waterborne Polyurethane (WPU) is a polyurethane system using water as a solvent or dispersion medium. In recent years, with the increasingly strict environmental regulations and the improvement of people's environmental awareness, waterborne polyurethane, as an environmentally friendly material, has received extensive attention and research. First, the characteristics of waterborne polyuretha...
①The residual ink is converted into gray black ink According to the principle of color science, the complementary color of the ink mixed together, its hue will become gray black (red + green, yellow + blue-purple). Therefore, we can use this principle to deploy the complementary ink into gray-black ink by deploying the special color ink, and add it to the black ink in a certain proportion to use i...
1.Touch optimization: the pursuit of softness and fullness In view of the frequent skin-to-skin contact of fabrics, the primary goal of the design of waterborne polyurethane coatings is to achieve soft touch and full form. This requires us to carefully balance the ratio of hard and soft segments in the formulation adjustment, while carefully selecting the types of both to ensure that the coating r...
In the process of UV flexographic printing, the viscosity of the ink is one of the key factors that affect the printing quality and effect. Choosing the right viscosity UV flexographic ink is crucial to ensure printing quality and efficiency. When adjusting viscosity, it is usually necessary to consider many factors such as printing equipment, printing materials, image details and the expected pri...
First, water-based lotion Aqueous emulsion is a colloidal dispersion system with water as the continuous phase and oil or other non-aqueous substances as the dispersing phase. It is a stable dispersion system formed by tiny oil droplets coated with surfactants. Water-based emulsion has many significant advantages, such as its low viscosity, easy to brush, easy to clean, non-toxic and harmless. The...
