The quality requirements for printing on the surface of pharma aluminijska folija su: ispisani tekst i uzorak su jasni i čvrsti, a nakon toplinskog zavarivanja na visokoj temperaturi, the text and pattern are still clear and do not change color. The bonding fastness of the printed text and the aluminum foil is generally identified by the adhesion fastness of the ink and the initial drying of the ink. The test method of adhesion fastness is: when the surface wetting ability of aluminum foil is 32-38x1O -5 N/cm, the general gravure method is used to print the ink, or the copper rod with a diameter of 9 mm is wrapped with a steel wire with a diameter of 0.12 mm. Scrape the ink on the aluminijska folija with a scraper. After the printing sample is placed for 24 hours, stick an adhesive tape on the ink, and roll it back and forth on the adhesive tape rolling machine for 3 vrijeme. The speed of .Om/s peels off the adhesive tape.

U ovom trenutku, the ink layer may be adhered to the adhesive tape and peeled off. Cover the tested part with translucent millimeter lattice paper with a width of 20 mm, count the number of lattices occupied by the area where the ink layer is intact, and then count the number of lattices occupied by the area where the ink has been removed, use A=A 1 / ( A 1 +A 2 ) x100% Calculate the adhesion fastness of the ink. In the formula: A is the area percentage of the adhesion fastness of the ink, A1 is the grid number of the intact ink layer after the test, and A2 is the grid number of the ink layer removed after the test. The adhesion fastness of qualified ink should be greater than 90%. Metoda ispitivanja za početnu učinkovitost sušenja tinte: Početni učinak sušenja tinte odnosi se na tintu pod određenom temperaturom (25 ± l ℃), određena vlažnost (65 ± 5%) i određeno vrijeme (30S) uvjeti, zbog isparavanja otapala, Slojevi tinte različitih debljina u početku postižu suhoću od tekućeg do krutog.

Metoda ispitivanja: Pripremite čisti tester finoće brisača. Pod gore navedenim uvjetima temperature i vlažnosti, upotrijebite staklenu šipku da pokupite tintu i brzo je ispustite na gornjih 100 um ispitivača finoće brisača. Ispunite cijeli žlijeb od 100 um do nule različitih debljina. Odmah pritisnite štopericu na vrijeme, kada vrijeme dosegne 30S, pritisnite 65g/m 2 crtanje novina s dužinom od 160 mm i širine od 60 mm na donjem kraju mjerača finoće strugala kako biste pokrili sve utore strugala. A 50-degree rubber roller rolls on the paper from bottom to top.

Uncover the paper, a certain amount of ink will stick to the paper at this time, the thin layer of ink may be dry and will not stick to the paper, and the thick layer will stick to the paper when it is dry. From zero, measure the length of the unstained ink in millimeters, and express the initial dryness of the ink in mm/30S.
