0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; let ’s first understand the definition of the use of water-based compound film

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Waterborne polyurethane adhesive refers to the adhesive formed when polyurethane is dissolved or dispersed in water. Later it was called water-based polyurethane or water-based polyurethane. In addition, water-based laminating adhesive is a kind of water-based polyurethane adhesive, which is generally used for laminating. The product has high solid content and is suitable for laminating of dry adhesive. The fast drying speed is required to dry through the drying channel. The high speed can reach 45 m / min, because the emulsion is a self-crosslinking type. When this compound is involved, its macromolecules will automatically cross-link, so the quality is relatively high, the overall performance is better, the powder can be covered by the powder, the product has good brightness, indentation, embossing, etc. Concavo-convex, no air bubbles, good toughness, smooth and beautiful, moisture-proof without glue, and the product has good storage stability, so in winter, it has good frost resistance, the storage period is 6 months, and the product is water-based adhesive, environmental protection , No solvent, non-flammable, non-explosive, safe to use.

The glue should be used to prevent freezing and sun protection, and it should be avoided in the summer. It should be placed in a cool place, then it should be stored in winter at above 0 ℃ If the glue is frozen, it can't be heated and thawed, and it should be slowly thawed in a room placed above 5 ° C. Then to observe the delamination phenomenon of anhydrous glue after thawing, it is to come in {{2 }} The mesh filter can be used for filtration, and it is to be sealed and stored during and after the glue is stored. It is necessary to reduce the skin and mold of the glue, so that it is to shorten the shelf life. Another thing is that the laminating adhesive cannot be mixed with other glues. It cannot be used to add other substances. It needs to reduce the chemical reaction, so it is caused by the loss, and it is based on the principle. It can't be added in Sheung Shui. There are also those that can be used for laminating after the printing ink needs to be dried. Another is that they need to be cleaned before the use of the coating roller. Net, come in the absence of rubber, the presence of impurities.
