Mae yna nifer o ffactorau allweddol yn y broses argraffu sgrin sidan o botel llwyd siampŵ
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. Yr ail yw ansawdd y sgrin argraffu sgrin y set cynhwysydd plastig. Mae ymwrthedd gwisgo, rhif rhwyll, tensiwn, a thrwch gludiog ffotosensitif y deunydd sgrin yn cael dylanwad mawr ar ansawdd y patrwm argraffu sgrin, trwch yr inc, halltu'r inc, a bywyd y gwasanaeth.
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. olaf yw y lamp UV cynhwysydd plastig gwag. Lampau UV yw'r offer allweddol ar gyfer halltu inc. Mae gwahanol gyfansoddiadau inc, lliwiau a thrwch yn gofyn am egni gwahanol ar gyfer halltu. Gyda gwahanol feysydd argraffu, mae'r dewis o fanylebau lamp UV hefyd yn wahanol. Felly, y dewis rhesymol o lampau UV hefyd yw'r allwedd i sicrhau cyflymdra'r inc yn llawn. Gellir asesu a yw'r lamp UV yn bodloni'r gofynion trwy brofi effaith y sampl. Ar ôl cyfnod penodol o ddefnydd, mae hefyd angen gwirio a gwirio a yw'r lamp UV yn heneiddio. Os nad yw'n bodloni'r gofynion, mae angen ei ddisodli â lamp UV newydd.
