01 permanent and can remove sexual choice In terms of the performance of binders, it is generally divided into two categories: permanent adhesives and removable adhesives. Permanent commonly used in electronic, mechanical, do not need to remove out. Removable is generally used for food or everyday items, such as fruit labels, clothing labels, etc. 02 The difference between objects to be affixed Self-adhesive labels may be attached to the surface of different materials, such as glass, metal, plate making and plastic. The surface texture of different materials is not used, so the selection should take into account the material to be affixed. If the surface material is rough, it needs a strong viscosity glue. 03 Influence of the surface shape of the attached object The surface of the object to be affixed has a plane and a curved surface. If it is curved, it may need a glue with good adhesion or strong viscosity, and a material with better softness and tensile resistance should be selected. The flat surface of the attached object ADAPTS to a wider range of label materials. 04 posted surfaces clean condition Self-adhesive material is most suitable for surface clean, dry, no oil and dust label base material. In any case, it is necessary to keep the surface of the paste dry and clean in order to achieve the best labeling effect. 05 Impact of environment on self-adhesive labels The labeling environment needs appropriate temperature and humidity to ensure the labeling effect. The use of the environment will also affect the choice of glue, extremely cold or high temperature special use of the environment for glue requirements are also different. Adhesive Advantage Disadvantage Applications Hot melt adhesive It belongs to rubber base adhesive. Strong fluidity, strong viscosity, suitable for low temperature use,non-toxic environmental protection. It is not resistant to high temperature, the processing process is sensitive to temperature, and it becomes hard and brittle when stored below -15℃. Poor reattachment, can not be attached to PVC material. Do not need too high temperature labeling environment, can be attached to food, medicine or supermarket labels. Water-based adhesive Belongs to the acrylic adhesive, strong viscosity, the vast majority of environmental protection non-toxic, relatively high temperature resistance. Below 90℃, a few below 150℃. Low temperature body surface performance is poor, the paste should be dry and clean, water-based glue fluidity is poor. It is used in food, medicine, daily chemical products, or industrial labels with strict environmental protection requirements. Solvent adhesive It is a kind of adhesive which is dissolved and coated with solvent as medium. It has strong viscosity, is not easy to overflow, is resistant to high temperature, and can be adapted to outdoor labeling. Not environmentally friendly, most are toxic, and the price is high. It is used for electronic labels and some labels for high-temperature environment ...

Particle size and hydrolysis resistance: The stability of the emulsion is closely related to the particle size and hydrolysis resistance of the polyurethane particles. The smaller the particle size, the better the stability of the emulsion. The poor hydrolysis resistance will cause the emulsion to degrade slowly during the storage process, produce carboxyl group, reduce pH value, and make the emulsion condense. Degree of neutralization: The degree of neutralization refers to the degree of reaction between the neutralizer and the carboxyl group. With the increase of the neutralization degree, the particle size of the emulsion decreases and the viscosity increases, which is helpful to improve the stability of the emulsion. However, too high a degree of neutralization will cause the viscosity of the emulsion to be too high, but reduce the stability. PH value: Fluctuations in pH value can affect the stability of the emulsion. An acidic or alkaline environment will cause the emulsion to coagulate. Therefore, controlling the right pH range is essential to maintain the stability of the emulsion. Storage conditions: High and low temperatures should be avoided during storage, as these conditions will cause the emulsion to condense and affect its stability. Solid content and drying speed: The low solid content of waterborne polyurethane will lead to increased drying and transportation costs, and the drying speed is slow, affecting its stability. In addition, the increase of solid content and crosslinking degree will also reduce the storage stability of the emulsion. Methods to improve the stability of waterborne polyurethane emulsions include: Particle size control: By adjusting the preparation process, the particle size of polyurethane particles is controlled within a reasonable range to improve the stability of the emulsion. Optimize neutralization: Adjust the amount of neutralizer according to the specific application needs to achieve the best emulsion stability and use effect. Adjust the pH value: During storage and use, the pH value is regularly tested and adjusted to keep it within the appropriate range to prevent the emulsion from condensing. Improve storage conditions: Avoid high and low temperature environments to ensure that the emulsion is stored and used at the appropriate temperature. Improve the solid content and drying speed: By improving the production process, improve the solid content, and optimize the drying conditions to improve the stability and use efficiency of the emulsion.
