Šampoonihalli pudeli siiditrükkimise protsessis on mitu võtmetegurit
1. The first is the pretreatment of plastic containers quality bottles. The surface tension of the bottle is directly related to the problem of ink firmness after printing. Generally, the surface tension of the material needs to reach 50dyn/cm, and the ink firmness after printing is more guaranteed. Products with strong material polarity can be directly printed. Although PET material bottles are of weak polarity, with the selection of appropriate inks, PET bottles can basically be printed directly without surface treatment. For bottles of non-polar materials such as PP and PE, the surface of the bottle must be treated. The general treatment method is flame treatment or corona treatment. A simple way to judge is to observe whether the surface of the bottle on the dyne droplet can be spread out, that is, it can be "hanging on water" to indicate that the surface treatment effect meets the requirements.
2. Teine on plastmahutikomplekti siiditrüki ekraani kvaliteet. Siidimaterjali valgustundliku liimi kulumiskindlus, võrgusilma arv, pinge ja paksus mõjutavad oluliselt siiditrüki mustri kvaliteeti, tindi paksust, tindi kõvenemist ja kasutusiga.
3. Again, it is the choice of mini plastic container ink. Different inks have different adhesion to the surface of bottles of different materials, and different color inks have different energy requirements for curing. Therefore, to ensure the fastness of the ink, it is necessary to select the appropriate ink for the substrate of the bottle. If you still can't meet the requirements, you can try adding an appropriate amount of auxiliary solvents such as a curing agent to the ink.
4. Viimane on tühi plastmahuti UV-lamp. UV-lambid on tindi kõvenemise põhivarustus. Erinevad tindi koostised, värvid ja paksused nõuavad kõvenemiseks erinevat energiat. Erinevate trükipiirkondade puhul on ka UV-lambi spetsifikatsioonide valik erinev. Seetõttu on UV-lampide mõistlik valik ka tindi püsivuse täieliku tagamise võti. Seda, kas UV-lamp vastab nõuetele, saab hinnata proovi mõju testides. Pärast teatud kasutusperioodi on vaja ka kontrollida ja veenduda, kas UV-lamp ei vanane. Kui see ei vasta nõuetele, tuleb see asendada uue UV-lambiga.
