Why is the hot melt adhesive laminating machine called environmental protection equipment?
What is hot melt adhesive? It is a plastic adhesive whose physical state changes with temperature in a certain temperature range, its chemical properties remain unchanged. Non-toxic tasteless, it belongs to environmental protection chemical products.
The product of the hot melt adhesive laminating machine is sturdy convenient for packaging, transportation, storage, solvent-free, pollution-free non-toxic. the advantages of simple consumer technology, high added value, strong adhesion fast speed. The combination of hot-melt adhesive laminating machine industry has also produced a hot-melt adhesive laminating machine, which is used in the processing manufacturing of various light industries.
Environmentally friendly water-based adhesives are environmentally friendly. Water-based film adhesives are a method to stop the appearance processing of printed products, improve the gloss strength of the printed products, enhance the aesthetic effect. To measure the quality of the film, you also need to check its brightness, strength, adhesion. The water-based wet coating has the characteristics of high strength, easy recycling no pollution.
The mainstream of domestic market sales, organic solvents have good permeability to rubber plastic materials. The use of domestic organic solvents has gone through different stages of benzene, toluene xylene. If these solvents are used improperly, it will seriously poison the operator pollute the environment. In 2003, the national standard "Adhesives for Shoes Bags" was formally promulgated implemented to restrict the use of benzene. Replace with ketones, lipids other mixed solvents to reduce toxicity.
There are two different types of hot-melt adhesives in the hot-melt adhesive laminator. Due to the above reasons, the following aspects should be done in the daily glue application process: the glue application temperature should be set according to the specified technical parameter values, when abnormal phenomena such as carbonization occur, the temperature control should be checked between the actual temperature The difference, the lid of the plastic box should be closed at any time to prevent the surface high temperature hot melt adhesive contacting with fresh air to accelerate oxidation. When a small amount of glue is used for a long time, the amount of hot melt glue in the glue box should be too large. One-third to one-half of the hot-melt adhesive can be added maintained multiple times, hot-melt adhesives that have been repeatedly heated for a long time can be removed replaced with new adhesives. Do use hot melt adhesives with two different properties.
