關於印刷機什麽是吹風乾燥器、電子束乾燥器

吹風乾燥器是利用鼓風機把空氣壓向吹嘴,使空氣在印刷品上進行強制性對流熱交換,達到乾燥的目的。根據需要,用吹熱風或冷風,使承印物上的油墨或上光液吹乾。但這種方式油墨或上光液乾燥速度很慢。

關於印刷機什麽是吹風乾燥器、電子束乾燥器

吹風乾燥器是利用鼓風機把空氣壓向吹嘴,使空氣在印刷品上進行強制性對流熱交換,達到乾燥的目的。根據需要,用吹熱風或冷風,使承印物上的油墨或上光液吹乾。但這種方式油墨或上光液乾燥速度很慢。


電子束乾燥裝置是利用電子束達到乾燥的目的,這種方式是近年國外發達國家,將原應用在穿孔、刻槽、切割等機械加工方面的電子束加工工藝,運用到多色高效印刷工藝生產中的一種新型能源轉換加工手段。電子束(EB)即通過電真空器件產生聚合、密集的、具有一定方向的電子流。

利用高功率密度的電子束加工方法,使從熱陰極發射的電子受控制電極及加速陽極的靜電場控制,而被聚成向同一方向運動的、密集的、截面很小的電子束。

當電子束沖到工件時,動能變為熱能,產生極高的溫度,可使任何材料瞬時熔化或氣化,被科學界認為是近期具有最佳處理一致性的乾燥技術。

它可使油墨、上光塗料最大程度地交聯和聚合,而無固化和溶劑殘留物,同時,熱能的利用率最高。
