Voith’s expertise: Guangxi BM 1 produces 1,200,000 metric tons of high-quality ivory board
The three-layer former concept with the newly developed DuoFormer D II provides for an optimal dewatering capacity and production speed. In the press section, the triple NipcoFlex press allows the highest dry content and thus low energy use. In addition, an excellent level of smoothness with a closed web run and thus extremely good runability are achieved by this press concept.
The outstanding surface quality and printability of the ivory board produced on the Guangxi BM 1 is essentially determined by pre-calendering of the unprocessed board before the coating machine. The innovative concept with the EcoCal Plus calender combines for the first time worldwide an oil-heated hard nip calender with an external induction heating system and an upstream nozzle moisturizer. The results are significant savings of raw materials. Very good surface quality is achieved by the use of DynaCoat AT coating units.
An EcoSoft Delta calender with two soft nips on the printed side is used before the reel for the first time so as to ensure a very uniform surface quality and improved board gloss. Then the board is wound in a gentle and controlled manner with the Sirius and processed with the VariFlex winder into paper rolls. Also included in Voith’s delivery were the chemical preparation, automation of the entire process and the system engineering.
The Guangxi BM 1 produces high-quality packaging paper which is suitable for all current printing processes such as flexographic, offset or rotogravure in a basis weight range of 180-350 g/m². The primary areas of use for the board are high-quality folded boxes for cosmetics and luxury items for the Asian market.
