Gen plizyè faktè kle nan pwosesis enprime swa nan boutèy chanpou gri
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. Dezyèm lan se bon jan kalite a nan ekran an enprime ekran nan seri a veso plastik. Rezistans nan mete, nimewo may, tansyon, ak epesè nan adezif la fotosensib nan materyèl la ekran gen yon gwo enfliyans sou bon jan kalite a nan modèl la enprime ekran, epesè nan lank la, geri nan lank la, ak lavi sa a ki sèvis.
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. Denye se vid plastik UV lanp lan. Lanp UV yo se ekipman kle pou geri lank. Diferan konpozisyon lank, koulè, ak epesè mande enèji diferan pou geri. Avèk diferan zòn enprime, seleksyon spesifikasyon UV lanp tou diferan. Se poutèt sa, seleksyon an rezonab nan UV lanp se tou kle a konplètman asire solidite nan lank la. Si lanp UV la satisfè kondisyon yo ka evalye lè w teste efè echantiyon an. Apre yon sèten peryòd itilizasyon, li nesesè tou pou tcheke ak verifye si lanp UV la aje. Si li pa satisfè kondisyon yo, li bezwen ranplase ak yon nouvo lanp UV.
