Description
Technical field
The present invention relates to the electron beam printing technical field, particularly a kind of electron beam printing deaeration plant and deoxidation method thereof.
Background technology
Along with improving constantly of material life, the consumer not only has been confined to visual enjoyment to printed matter, and the requirement of product environmental protection aspect is also being improved constantly, and this has proposed the new ideas of environmental protection just for China's printing industry.In press, printing ink also develops towards fast dried, nontoxic and environmental protection direction, and more representational is exactly water-based inks, UV curable ink and electron beam radiation cured printing ink.Using more energy-curable technology at present mainly is that the UV photocuring solidifies two kinds with acceleration high-power electron beam (EB).
Wherein, electron beam radiation cured printing ink is meant the printing ink that adopts beam energy to solidify.Be exactly printing ink down in the radiant energy irradiation, set or be hardened on the stock, thus obtain the trace of drying.The advantage of electron beam curing ink is a lot:
(1) solid content after it solidifies is 100%, does not contain organic volatile matter (VOC), belongs to zero-discharge technology;
(2) because the radiation of main dependence high voltage low current electron beam realizes the drying of printing ink etc., save energy, practiced thrift production cost;
(3) hardening time of electron beam curing ink very short, general only needed 0.1 second can anchor at substrate surface by finish-drying, thereby increased substantially operating efficiency;
(4) the printing ink marks of electron beam curing ink printing has very strong resistance; Form the high molecular weight steric network polymers because of the chemical substance in the printing ink through cross-linking reaction simultaneously; So ink pellet surface has very strong chemical-resistance and crocking resistance, can also guarantee the clean no dirty point of printed matter surface, little, the trace good brightness of dot gain rate.
Though electron beam curing ink has a lot of benefits, still there is certain shortcoming, its curing apparatus cost height is an obstacle maximum in applying.For example: though when solidifying, EB only needs an ion cathode tube, and must the indoor active gases content (like oxygen) of strict control cured.Way commonly used at present is when electron beam curing apparatus 20 is cured; Increase a nitrogen protection storehouse 10, as shown in Figure 1, through 10 li inflated with nitrogen in the nitrogen protection storehouse; Require nitrogen gas concn to be not less than 99.5%, make that the printing ink on the stock can make itself and oxygen completely cut off when EB solidifies.So, the EB curing apparatus is very complicated, and cost is very high, is unfavorable for the large-scale promotion of EB curing technology.In addition, when sheet-fed prints, can't utilize EB to be cured, also be the problem that can't overcome in the present EB curing technology.
In view of this, prior art is still waiting to improve and improve.
