Hot melt (glue gun) adhesive is widely used, if the price with the equipment and materials can be cost-effective. Hot melt adhesive application packaging industry accounts for more than 50% of the market, these packaging materials, including folding cardboard boxes, corrugated boxes, laminated materials, cans, tape, and other overlapping synthetic coating materials. Non-woven textile containing sanitary napkins, disposable diapers, clothing fit, stitch bonding and so on. Woven products including garments, seam, tape, carpet gum. Office supplies including tape, documents, self-adhesive labels, envelopes folder. Part portfolio, including soft drinks, electronics, books, packaging, furniture, shoes, handicrafts, DIY, and wood, plywood and so on.
2, the use and application of hot melt adhesives should pay attention to things
Hot melt adhesive applications because of the scope, its clean, pollution-free characteristics, but also to replace the solvent based, have great advantages. However, the restrictions on their properties. The application should be particular attention. In this list a few.
(1) Viscosity
Melt viscosity for the operation of key indicators, due to hot melt adhesive must be used by means of heaters, which coating machine. In general, different industries, different purposes, there are different things, different coating machines, coating method, they have determined the melting viscosity. Should note in this
Italy is from the same purpose, but different manufacturers of coating machine and method, cooked viscosity of sol are also different.
(2) Curing time, hours
The use of hot melt adhesive as the medium, after cooling gel is then completed. Therefore the use of operating time to pay attention to the control.
Cure time (setting time): means the coating formed after a short time then the best.
Hours (open time): refers to pressing can be coated to allow the most time.
(3) Temperature resistance:
EVA hot melt adhesive system of the physical properties of their own restrictions, conditions in the temperature of its heat resistance at 40 ? ~ 65 ? between the melting point of the main general EVA also between 40 ? ~ 70 ?, while the TPR itself The heat resistance is better, but often have added plasticizers and reduce the heat resistance.
