Introduction of hot melt adhesives
Hot melt adhesives are thermoplastic adhesives that are solid at room temperature but liquefied at higher temperatures. Melt the liquid temperature of the substrate, when the cooling layer hardening, the formation of gluing. A typical melting temperature is 65 ° C to 180 ° C. Since it does not contain any solvent as 100% solids, it can meet the most stringent air pollution control requirements, and there is little risk of fire or explosion. In addition, the hot melt adhesive on the user has the following advantages:
Curing speed, reducing the amount of compression required for gluing, so the production speed can be increased, the equipment space is also saved.
Can then be applied to a water-based surface without the need to use a wetting agent. It is water-resistant, storage stability is also excellent.
Since 100% of solid content is completely usable, there is little waste to reduce transportation and storage costs.
The substrate can be followed by a wide range, can be automated.
Types and Uses of Electronic Products Using Hot Melt Adhesives.
1, speakers, music stand: straight V, horizontal V, triangular wood reinforcement, decorative strip edge.
2, television sets, monitors: electronic components fixed, video tube and bias ring sealing.
3, PC board parts fixed row weaving, packaging and then cushioning material to corrugated boxes and so on.
