one, dry composite with polyurethane adhesive choice
1, dry food packaging: huangyan new Oriental PU180
2, boil with: angie 175 and huangyan new Oriental PU8850
3, transparent cooking bags with: domestic cooking glue
4, aluminum foil cooking with: import cooking glue, such as the United States morton company 585 K, Japan Oriental chemical company AD502, quality ink company A310, German hankel company UK3640/6800.
Second, diluted and coating
1, diluted for solvent acetic acid. Pu adhesives made order: the agent to the dosage gradually add solvent fully mixing, add hardener stir well and become even solution to again after use, adhesive used for 20%-35% concentration usually (dry base including solid amount), 3 # viscosity cup (ChaEn cup) 18-25 s.
2, the applicator roll general selection nets roller, light roller, the coating with use of packaging and decide. Coating is enough often appear quality accident, such as composite membrane appearance and cohesiveness bad, prone to take off layer, heat sealing, boil, cooking, etc. Various kinds of patience in the best coating adhesive volume, want to consider to base material structure, printing the size, composite membrane processing conditions and after end use.
3, dry: to make with adhesive in the film of complete volatile solvent, to make the film through the oven. Then should pay special attention to air volume, wind speed and temperature of process parameters, general drying temperature for 50-80 ℃.
4, component: dry composite processing with thin film, shall be subject to the above thirty-eight dyn corona processing (BOPP, CPP), PET and PE film, surface tension for 42 dyn above, nylon membrane, namely PA or ONY for 52 dyn above. Composite rolls temperature for 50-80 ℃.
5, maturation: compound after treatment, needs to be sent into maturation room, promote the Lord agent and curing agent reaction in the, in order to get the best composite strength. (composite film in a certain temperature preservation certain of time, this process is called age). The average temperature ± 50 tended to 5 ℃, the time 1-2 days. For adhesives, composite structure, product and so on the different and different.
