Powder removal principle

Powder removal principle

1. Clean water coating powder remover: The clear water coating powder remover uses the roller coating system to apply the clear water map printing to the printed matter through the rubber roller. During the coating process, the damp water film on the rubber roller will be adhered to remove the printing. Powder spraying to achieve the purpose of powder removal, in the de-powdering process, the paper surface humidity is high, the paper is easy to expand and contract. The government policy and supervision, the powder removal effect is low, the removal rate is only 30 to 40%, and the paper back pressure is sticking Dust is not removed and re-stacking will cause secondary pollution.

2. The brush stick sweeping powder suction powder single-sided powder remover: This kind of powder remover equipment sweeps the powder through the brush stick on one side, and at the same time removes the paper printing dusting financial crisis through the suction pump suction, and the removal rate reaches 40 ~ 50%, but can not remove the printing powder adhesion with the ink layer, single-sided powder back dust can not be removed, re-stacking will cause secondary pollution.

3. Heater hot press powder remover: This type of powder remover is heated by heating roller; hot pressing stick electrostatic adsorption printing powder powder, and remove the ink adhesion powder layer Shanghai Hongjing by hot pressure, this addition Powder principle works only, can only remove the print volume is very small print, except for the powder rate is only 30 to 40% single-sided addition of powder back pressure can not remove the same dust, re-stacking caused secondary pollution.
