high frequency embossing machine Vendor.Why is ultrasonic laminating machine also called environmentally friendly equipment

　　What is hot melt adhesive? A plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties are stable, non-toxic and odorless, and it is an environmentally friendly chemical product.

　　Due to its solid nature, the product is easy to package, transport, store, solvent-free, pollution-free, and non-toxic; It is highly favored for its simplicity in consumer technology, high added value, high bonding strength, and fast speed. The combination of hot melt adhesive and ultrasonic composite machine industry has led to the development of ultrasonic composite machines, which are used in various light industry processing and construction.

　　Environmentally friendly water-based adhesive is environmentally friendly, and water-based laminating adhesive is a method of processing printed materials, improving the brightness and intensity of printed materials, and enhancing aesthetic results. To balance the quality of film coating, it is also necessary to assess its brightness, strength, and adhesive strength. Waterborne wet lamination has the characteristics of high strength, easy recycling, and no pollution of its coated printed products.

　　The mainstream of domestic market sales is that organic solvents have good permeability to rubber and plastic materials. Domestic organic solvents have experienced different stages of use, including benzene, toluene, and xylene. If these solvents are not taken properly, they will seriously poison operators and pollute the environment. In 2003, the national standard for adhesives for shoes and bags was officially announced and implemented, limiting the use of benzene. Replacing the use of mixed solvents such as ketones and lipids to reduce toxicity.

　　Environmentally friendly water-based adhesives and hot melt adhesives should be the direction of adhesive development. According to experts from Adhesive Network, environmentally friendly water-based adhesives use water as a solvent, while hot melt adhesives as solid adhesives do not require solvents. In fact, ultrasonic embossing machine manufacturers have addressed the basic issue of toxicity. Solvent free responsive polyester hot melt adhesive, stops cross-linking with the help of moisture or heat transmission, and achieves good bonding strength at the beginning. Hot melt adhesive is a high-performance and environmentally friendly adhesive. Compared to solvent based polyurethane adhesive, water-based polyurethane adhesive has no solvent odor, is non-toxic, pollution-free, residue is easy to clean, has a high solid content, and is easy to handle. In the 1990s, environmental regulations in Western countries became increasingly strict, and waterborne polyurethane adhesives were industrially applied.
