Funkcija nanosa lepilne plasti na drugo stran aluminijaste folije je lepljenje aluminijaste folije na togo plastično ploščo (PVC), tako da je zdravilo zaprto. Pri nanašanju lepila, treba je zagotoviti najbolj enakomeren premaz, in razliko je treba nadzorovati znotraj standardnega območja;

Metoda odkrivanja razlike v količini prevleke aluminijaste folije je naslednja: uporabite a 1/10,000 uporabiti analitično tehtnico 5 vzorcev 100 mm x 100 mm od končne aluminijaste folije in jih ločeno stehtajte. Nato uporabite etil acetat, metil etil keton ali druga topila za brisanje lepila in nato stehtajte, razlika med obema utežmama je količina nanosa lepila, and the average value of the coating amount of the three pieces is calculated. The difference between the coating weight and the average value shall be less than ± 12.5% prenesti.

Testing of the heat-sealing strength and quality of the adhesive layer of the medicated aluminum foil: using a lever-type heat sealer, a standard test piece cutter, and an automatic recording tensile testing machine. Cut 2 kosov 100 mm x 100 mm test pieces from the finished product, in rezati 2 kosov 100 mm x 100 mm test pieces of pharmaceutical PVC rigid sheets that conform to GB5663.

The set temperature of the heat sealing machine is 150-160 ℃, tlak je 0,2x1O 6 oče, in čas je 1S. Med delovanjem, superimpose the adhesive layer of the sample with the PVC sheet, insert it into the heat sealer for heat sealing, and use a standard cutter to cut into 15 mm široki vzorci, and take the middle three strips for use by the automatic tensile testing machine.

Preskusna metoda: Adjust the tensile testing machine and make the pointer of the recorder zero, set the tensile speed to 200mm/min, clamp the PVC in the sample in the upper gripper of the testing machine, and clamp the aluminum foil layer of the sample in the tester. In the lower gripper of the machine, start the tensile testing machine and carry out the 180-degree direction peeling.
Pusti. The automatic tensile machine will automatically record its value, and the data should take the average value of the curve drawn by the automatic recorder as the heat sealing strength value of the sample. Its value should be greater than 5.8N/15mm to be qualified.
