Product description

Application of corona machine

Corona treatment machines are commonly known in the packaging industry as corona machines, electronic impact machines, and electric spark machines. It is academically called a dielectric barrier discharge. Mainly used for plastic film -based or plastic surface treated sheet material product type, to be performed when the ink is printed, composite, blown film, coating, adhesive, material modification, the polymerization of the above material coating, casting, paste before processing in order to make the surface of the product having a stronger adhesive force (i.e. having a higher coefficient dynes), to prevent the raw materials in the production process is now printing rejection color, the composite paste is not solid, plastic coating unevenness leakage phenomenon, influence In order to improve product quality, corona impact treatment must be performed first.

 

Corona principle

利用高频高压电源,在放电极与电晕辊之间产生电晕,形成低温等离子区,通过两极之间的空气电离,产生臭氧,臭氧是一种氧化剂,可以立即改变塑料表面的分子结构,使其由非极性转化为极性。同时电晕后会使材料表面呈微小凹凸不平的孔穴使其表面粗化,增强表面活性,这样表面张力得到提高后,既油墨、胶水等就能进一步渗透到被处理材料上,从而达到理想的印刷及上胶效果。

 

电晕机的功能及特点

电晕机根据所要处理的物体的形状不同分为不同的结构方式,但电控部分大体是相同的。

绝缘材料电晕处理机适用于处理PP、CPP、BOPP、PE、PET、HDPE、LDPE、PS、PI、PS、PC、PA、PVC、ABS、

无纺布、合成纸等材料膜、板材、片材的表面湿润张力处理;

导电材料电晕处理机适用于处理铝箔、镀铝膜等材料膜、板材、片材的表面湿润张力处理;

异形材料电晕处理机适用于各种异形塑料件的表面湿润张力处理;

u 目前合丰制造的电晕机主机采用稳定、先进、可靠的进口大功率IGBT模块、器件为主电路元器件,控制、触发、显示电路的主元器件由集成块电路组成,数码显示,使其设备运行时十分安全可靠、耐用,故障率低,并具有过压载、过电流、短路及停转等自动保护等优点,是目前国内外电晕界比较流行的趋势。由于功率器件IGBT的使用,产品结构简洁、电路连线简单、可靠、高效率、小体积、使用简单、一键操作、结构模块化,维护方便。
