Sappi Maastricht: using three laminar plasma box and metal belt type calender, the production high quality high whiteness and takamatsu thick cardboard

Used in the production of blue folding carton board is to use an d produced by virtue of the metal belt calender.Sappi products research manager Jos Daniels said: "d virtue Mika Viljanmaa shows us with one of China's paper machine production of the box.These box looks fantastic.We want to achieve similar high-end appearance, but in the manner the Sappi."

Product upgrade how to do?

A few years ago, Sappi Maastricht realized that their customers want paper folding carton board (FBB) with the current drawing paper as good surface quality, comfortable sex and whiteness.Sappi central technology and the engineering director Wim Devens explained the situation: "our customers start using our drawing paper folding box used to do.This is by no means we produce paper grades of original ideas."

In order to meet customer demand, Sappi introduced called Atelier cardboard, but as a result of customer complaints, the production of the product was cut."We know where we need to improve, and" Sappi technology managerTjerk BoersmaSaid.But, like renovation project, also have limitations: only a flow slurry box existing machines, then there is the budget.

The idea of papermaking production line is equipped with three laminar plasma box

Starting with a metal belt type calender start the project, but soon realized project need more reform.Due to the existing paper machine is a single layer flow slurry box, factory require d virtue to provide a three layer flow slurry tank.

Sappi and the virtue of engineers work together to achieve their common goals."During the development and transformation of cooperation very smoothly.A good relationship with their engineers.Hail to the team!"Sappi craft and the quality managerRob DE KoningThe project is introduced.When design starts to look good on paper, they need to better understand this concept.

Through pilot test this concept

Millions of dollars of investment, you need to verify before actual decisions."There is no doubt that it will add value."SappiMaastricht factory directorFerdinand KosterWhen it comes to d virtue pilot facility."Has this ability is very important.You can apply learned lessons to built in the paper machine is."Boersma said.DE Koning stressed: "we can get the required validation.We can without losing thickness, stiffness, and surface properties of the cases, the packing content increased by more than 5%.

Although the technology has been more reference case, but still need to verify before actual decisions..Jos Daniels, when it comes to dimensional virtue pilot facility, said: "we are very satisfied, the pilot results to show the way forward."DE Koning stressed: "we can get the required validation.We can without losing thickness, stiffness, and surface properties of the cases, the packing content increased by more than 5%.

Then, still need to convince top management: "we need to prove that you can run three laminar plasma box, to convince the leadership of our headquarters in Brussels."The transformation of Sappi technical personnelJean PeerlingsContinued.

Carefully preparation, obviously, Sappi Maastricht adopts the solution is to use new three laminar plasma box and metal belt type combined calender."We need these two technologies, a used for layered forming, another is used for surface and improve thickness."Sappi Wim technology and engineering center director Devens concluded.

The first three laminar plasma box: greatly reduced operating costs

During the period of transformation, Sappi Maastricht using new flow slurry tank to replace the old flow slurry box, three layers feed at the same time.Is not
Maastricht in the production of all products (drawing paper, white paper board, SBS, FBB) are traditionally hierarchical, but found layered all cardboard factory product can bring value.They have for each product, quality and cost of each layer was optimized.

"With three separate flow slurry box will require a huge investment, is ten times as much as we need investment."DE Koning said.Using three laminar plasma box can also save a lot of operating costs, Boersma explained: "the scheme can save a lot of cost.Using three flow slurry tank, you will have three net, containing all the many chemicals and water.Cleaning and replacement of the net take a lot of time.Therefore, it is not only the problem of investment, but also energy, chemicals and consumables costs must be considered."
We achieved with the use of three flow slurry box the same quality of products.In fact, compared with using three flow slurry box, we can even produce better board."

Very smooth surface and the thickness of takamatsu

An innovation plus another innovation will be more beautiful.Even after ten years, the metal belt type calender is still a unique technology, because of its length, the metal belt support area of the calender, provide excellent surface performance and keep the board thickness."We are a drawing paper production factory, need to improve the quality of the cardboard double surface, and the only have the ability to do this equipment is a metal belt type calender."DE Koning said."Metal belt production and running well.It is doing his job.No problem."Boersma added.

Using the Opti - Calender metal belt type Calender production very smooth surface and thickness of cardboard takamatsu

"There is a rough road is better than no way"

Today, Sappi Maastricht production of high-end products, has excellent quality and folding performance.Their Atelier product is a blend of different products of best quality: optimum printing of drawing paper and the surface properties, SBS, whiteness and FBB thickness, stiffness and crease resistance.

"After transforming our products qualified soon, especially the drawing paper products.Products without complaint.Cardboard surface more smooth,
Flat and level.Pleasant to print and has further improved machinability."DE Koning said."I just made a start up project better.We should all for our proud achievements in a short time."Sappi PeterPijpers Maastricht and Lanaken technology and engineering manager said.

Innovation is prevalent in Sappi for a reason: "innovation is the key to Sappi driving force.Not everyone is willing to take risks with the first prototype.Become a pioneer in will not be easy.Most factories are more willing to become a follower."Peter Pijpers said.When you develop and build new things, is a learning process.Sappi Maastricht has learned how to Atelier series products."We're now continue to optimize.It is a long way.However, there is a bumpy road is better than no way!In the current market situation, if not, is no way out."Pijpers said.

More flexibility in the future

The first batch of samples by the enthusiasm and positive feedback of the market."Customer very pleased with our board, high whiteness, good thickness, and pleasant to print and running performance is very good also.This is the purpose of the project implementation.They compare our products with the SBS board, because our high whiteness and even more than SBS."DE Koning said.

"Maastricht unique, because we put the drawing quality and Atelier FBB quality together.I'm uncertain
Decide whether there are other factory can do that - in any other place I have never seen such a good product.No cracks, is very perfect.Metal belt type calender surface of the board.We can see that the thickness increase, have good surface properties.We produce such beautiful, silky products."Daniels stresses.

"Atelier provides extreme brightness, purity and luster, smooth tactility, coupled with the thickness and stiffness, represents the folding carton board market really new territory."

More flexibility in the future

We spent some time achievement of today's Sappi Maastricht, and the future looks good."Review the cooperation with d virtue, going very well."Koster said the project summary."Flow slurry tank and the combination of metal belt type calender makes our production is very flexible, can produce many different products."Pijpers said.

Flexibility not only limited to the equipment."You can be flexible enough to produce high-end products, but you also have production meet the requirements of low flexibility of low-cost products.We can choose cheaper raw material, the adjustment of product variety and quality.I hope we can soon to the market said: 'if you want this, you can buy it at a certain price."' this is what the customer: from Sappi Maastricht luster bright beautiful board.
