editorial Austrian industrial companies have been complaining increasingly about the existing lack of skilled la-

bor. This might seem absurd at first in view of increasing unemployment. Unemployment and lack of skilledlabor, however, do not, on principle, contradict each other.

The traditional image of the industrial company has developed itself to an innovative high-tech facto-ry. The traditional industrial jobs are also subjected to extremely complex activities with high-quality de-mands. The trend towards automation and consumers requests for high-tech products do not demand la-bor with simple or only outdated expertise.

Instead, the demand for well-trained skilled labor, being up-to-date with newest technology, as well asfor creative skilled workers has been growing considerably. The search for such employees endowedwith those conditions has, however, turned out to be very difficult for employers.

The declining number of graduates in science and engineering – especially in Austria – gives reasonenough to cause concern in the Styrian industry. For this reason, initiatives for the support of the educa-tion system need to be taken. Read more about it on page 6.

Also the GAW Group would not be able to meet the demands of the local and global markets withoutits highly qualified skilled labor and key men. The satisfying order volume of the current business yearhas been proving again that our employees meet these qualification demands.

A proof for our successful corporate policy would be our business partner Felix Schoeller junior in Os-nabrueck/Germany. GAW has been doing business with this paper mill for many years which has beenrelying on GAW’s profound competence. The coating color processing for the coater 6 at the plant inWeißenborn/Germany is a very sensitive project. It produces photo paper and special paper which re-quires a lot of expertise and experience. I am convinced that we will finish this project – whose techno-logical demand is on the highest level – profitably for both parties.

I wish all employees and customers as well as theother readers of imteam a Merry Christmas anda successful 2006, being aware of the fact thatGAW Group is prepared well for the increasinginternational competititon.

GAW propellor-agitated mixerProcessing of media without inclusion of air

The GAW propellor-agitated mixer is able toprocess media very urgently under the influenceof temperature with very little or even no inclusionof air.

The modular construction of the agitating ag-gregate ensures simple assembling and opera-tion. In addition, maintenance and compatibilitywith other GAW products are guaranteed.

Construction

The color mixer illustrated on this page consitsof a tank with a double mounting construction.The teflon-coated interior prevents a sticking of themedia to be processed. Moreover, this specialmixer ensures a continuous reaction and pro-cessing temperature for the whole mixing process.

Due to the combination of anchor and blade ag-itator, a maximum temperature exchange is guar-anteed. This specific exchange happens via thetank´s mantling surface without requiring staticflow breakers. The special geometry of the mix-ing blades ensures that the media are processedmost gently.

Frequency-controlled drives enable individualrevolution speed (rpm) at different filling level andtherefore ensure optimal conditions during thewhole processing.

sponding process sequence, the controlling unitalso consists of a data base in which relevant pro-cessing data is being saved.

The programme can be found directly on theCPU (Central Processing Unit) in the control unitsin smaller plants. In this case, the plant’s data canbe read and changed directly with a panel or aPC.

GAW’s coating color kitchens mostly work witha server-PC1, the core of each controlling unit. Thewhole controlling unit and visualization2 of theplant can be found there. This system is set up re-dundantly, meaning that a second computer is em-ployed parallely as a substitution to the server-PC.In case of any occurring problems, the controllingunit and the visualization will be switched to thesecond computer which ensures a secure availa-bility of the system.

The server is connected with the peripherals(I/O3 electronic devices, frequency converter, lo-ad cells) via a profibus interface (Process FieldBus). The network connection (Local Area Net-work4 serves its purpose to connect the server with

Structure of industrial control systems

The control of a coating color kitchenThe complete functions of relays or switches we-

re carried out before the time of computerizedcontrols. This meant that a great space and wiringwere required which were, of course, prone tomany sources of error, such as wiring errors ormechanical mistakes of the relays and switches.

Another problem was the flexibility of such sys-tems. A great wiring effort had to be undertakenin case of any changes. It is needless to mentionthat a lot of time was involved.

With the introduction of SPS (memory pro-grammable control) controls were constructedwith less space required and these controls wereincreasingly automated. In general, the term con-trol means the process of a change which doesnot course by chance but on control. The term con-trol engineering is used accordingly for certain in-stallations which influence technological proces-ses based on given plans. Structure and its modeof operation are illustrated with the following ex-ample.

The control of a coating color kitchen

Industrial controls serve their purpose to cen-tralize the control of plants. In other words, mixingequipment, starch and pigment processing plantsand storage of raw material of a coating color kit-chen are checked and controlled by a central con-trolling unit. Apart from the recipe and the corre-

other termianls (panels, other PCs, …).The I/O assemblies are responsible for the ana-

lysis of the signals in the data field and transmitthe signals via the profibus to the server. The ser-ver then analyzes the signals and saves them on-to a data base. The plant is operated with a vi-sualization unit which incorporates mumerousoperation and display units (switch, sensor, dis-play).

The part’s components are divided into severalpictures, in which smaller parts are put togetherfunctionally. The operation occurs at decentrali-zed built work stations ranging from manual con-trols of the valves to the input of the complete mi-xing of coating color recipe.

Planning and installation

The exact engineering of the controlling unit foreach project is carried out in intense arrangementbetween customer and GAW. The whole installationand starting up are carried out by the electrotechni-cal department.

Self-adhesive label paper

Self-adhesive label paper has been required in-creasingly not only in the computer industry, but al-so in the food and cosmetics industry as well as forpharmaceutical use.

Due to the coating on the back of label paperwith pressure-sensitive adhesive, the label paper re-mains sticky and can therefore be put on to variousmaterials after the protection film has been re-moved without any previous moistening and pres-surized heat exposure.

Quality with GAW technology

The quality of a self-adhesive label is considerablyinfluenced by the relation of adhesion and cohesion

GAW – continous mixer for the production of pressure-sensitive adhesive for labels Biggest plant worldwide goes into operation

At the end of this year, the biggest plant world-wide for the production of self-adhesive label pa-per goes into operation in the province of Guang-dong, in the South of China.

Continous mixer by GAW

Guangdong Guanhao High Tech Co., Ltd. isemploying a GAW mixing plant for the process-ing of the pressure-sensitive adhesive. The wholeorder includes the unloading and storage of acry-late and resin, the stocking of process materials, acontinuous mixer as well as the metering to theworking stations.

of the different mutual components for the produc-tion of pressure-sensitive adhesive.

The accurately produced recipe for the particularapplication in the GAW mixing control is controlledonline with high-tech measuring instruments. Variousrecipes are developped with GAW AutomationXand they are applied in the processing optimally inregard to its quality.

The produced pressure-sensitive adhesive mainlyconsists of acrylate and resin as well as different ad-ditives which influence the coating performance ofthese materials interacting with each other - calledrheology - on the carrier substrate, the immobiliza-tion as well as roughness of the adhesive layers.

The company Guangdong Guanhao concen-trates mainly on the production of special paperwith a yearly output of 65,000 tons of self-carboncopy paper, thermo-sensitive paper and inkjet pa-per. The processing of the coating color is carriedout – amongst others – by a GAW multi-functionalcoating color kitchen of the year 2003.

GAW PCS – VST-Dispersion System for Dow Chemicals

Production with highest solid content Dow Chemicals, the largest chemical company

in the world, ordered four VST-Dispersion Sys-tems for producing coatings for paper, paper-board and labels. VST is an acronym for VariableShear Technology and is based on the infinite ad-justability of the overlapping of rotor and stator dur-ing the operation. Thus the operator has the possi-bility to set up the optimum combination of productcirculation and shear ratio for each respective ap-plication and formula.

Optimal for products with highsolid contents

The VST-Dispersion System is applied for the dis-persion of pigment slurries with high solid contents,for the preparation of complex formulations and inthe direct metering of dry components.

Dow Chemicals benefits from the refitting of theexisting system to GAW‘s VST in many points as forexample:

● Processing of shear-sensitive products using vari-able stator position

● Improved particle size distribution and homo-geneity due to variable shear ratio combinedwith adjustable product circulation

● Saves energy through faster metering of com-ponents combined with even shorter batch times

● Significant savings of binders and additives incombination with highest solid contents and op-timal viscosities

● Avoidance of air intake leads to reduction of aircontent of the product

GAW-Sodium-dithionite-dissolving units Start up at Norske Skog in Brazil – a report by Robert Mayerhofer

Apart from numerous plants in Europe, a sodium-dithionite-plant has been put into operation at thepaper mill Norske Skog Pisa, Brazil, recently. Thedissolving unit, which was co-developed by GAWand BASF, will be used for cellulose and kaolinbleaching.

From autumn into spring

After take-off in Graz at autumnal temperatures,the landing took place in Sao Paulo in middle ofspring at pleasant 20°C. After 6 hours delay, theplane took off to Curitiba, the capital of the federalstate Paraná.

The arrival in Jaguraiaiva finally took place af-ter a total travel time of 27 hours.

Start up

The start up of the already delivered dissolvingstation as one unit began with the electrical andpneumatical connecting of the parts components.After the terminal had been built up in the opera-tion station, the modem connection for the remotemaintenance was ready to be tested.

Since the water test had already been tested atGAW in Graz, the dissolving plant was taken into

operation within only a short time. The customercould verify that the plant ist equipped with the max-imum security features and is therefore not prone toany productions loss.

The teamwork with BASF and Norske Skog col-leagues proved to be excellent during the fourdays´ start-up.

The “calm” working philosophy of the Brazilianpeople was, however, not easy to deal with. Thephysical well-being was taken care of by excellentsteaks and fish dishes and therefore it was not sur-prising that I came back with more weight on myhips.

Dagang III – world’s biggest papermachine for online-coated paper

goes into operationA building site report by Erich Hirschbeck, GAW erection-supervison

The world´s biggest paper machine for the pro-duction of online coated paper took up its opera-tion at the company Gold East Paper in Dagang,situated in the chinese province Jiangsu (see issue2/04).

The system for the coating color processing anda wet grinding mill for natural calcium carbonatewere delivered and taken into operation by GAW.Erection supervisor Erich Hirschbeck reports:

Apart from the erection and start up of the newplants, the order also included the expansion of theexisting GAW-coating color kitchen II. The PC-sta-tions of the AutomationX system had to be first re-placed with new and more efficient ones during theoperation.

We started with the actual transformation worksin January 2005. We had to move both of the ex-isting large and small additive-dosing stations forthe supply of the OMC II during the standstill of on-ly 48 hours of the coating color processing. In ad-dition, a new coating color mixing machine with acapacity of 17 m3 and the process control systemAutomationX had also to be integrated.

The necessary switching-off of the complete pow-er supply during the MCC-expansion led to such agreat fall in temperature which let the water freezedue to the high amount of humidity. The Chineseerectors, who were dressed in only light clothes,even had to make a fire in order to warm them-selves at least a little bit. Due to the perfectly timedcoordination between my collegues from the elec-tronic department and me from the mechanical su-pervision, the plant was ready resuming its opera-tion.

I encountered great strain during that time, es-pecially when I got informed about my wife whohad to be taken to hospital. GAW enabled me, ofcourse, to fly home immediately. The people in Da-gang who I have known since 1998 and withwhom I share close contacts, bid me farewell.

After three weeks´ stay in Austria, everythingturned out to be fine. Thanks God. I was then ableto fly back to China and to commence my workthere. We started highly pressurized with the fin-ishing of the coating color processing for the sup-ply of the PM III.

A 17 m3 coating color mixer with all dosing lines,a new starch plant with 3,500 kg/h atro, a CMC-mixer and the coating color storage including thesupply plant for the PM III were installed. The clay

processing was expanded by a 12 m3 mixer andby serveral small plants. The plant´s componentswere taken into operation gradually after comple-tion. At the same time we also started with the erec-tion of the GCC-plant existing of 10 mills with a ca-pacity fo 1,000 liters each. 710 tons of Hydrocarb95 are grinded daily in 4 mills; in the other 6 millsthe grinding of 370 tons of Hydrocarb 65 takesplace every day. After the integration of the Au-tomationX-system and a one week testrun, the so called Operation Test Runwas completed successfully in July.

The way to the start up was ac-companied by a lot of ups but alsosome downs. When we had to bringa colleague with a broken toe to hos-pital to Dagang, we had to pay firstbefore the doctor actually came tosee us. At the hospital distastrous con-ditions still exist. Couple of months lat-er the same colleague also cut his ten-dons on his palms into two and there-fore had to go to hospital again. Thetransfer to the sick room was a sur-prise. Nurses like we know in Europedo not exist. Everyone must gethis/her own stuff if he/she needssomething. For example the food isbrought by family members. We re-alized that my colleague had to betaken home immediatley when hisneighbor smoked a cigarette duringan inhalation (!) and his daughterwashed her feed in a basin.

Although China is a very fascinat-ing country, great endurance is de-manded in general. Hungry childrenin dirty clothes without any prospectof education. Men and women dragtheir wheelbarrows crowded withthrash trough the streets and searchfor left-overs at home. The streets arecrowded with cars – speed limits,trafic lights, double crossing linesand zebra crossings are being ig-nored. The police can not cope withthis traffic and deadly accidents hap-pen regularly.

Gold East Paper is the world´s biggest art paperproducer. The production of presently 1,6 milliontons of paper is done in four shifts with 4,800 em-ployees. It is planned to increase the output to 2 mil-lion in 2006. Both of the offline coating machinesand the new online coating machine are suppliedby GAW coating kitchens.

GAW Quality-LoopOnline-monitoring system placed on the market

The GAW Quality-Loop, which took up its real-time operation first in 2004 within our PM 4 pro-ject at the paper mill LEIPA / Germany, has beendelivering several 100 operating hours of continu-ous measuring data. This online-monitoring systemhas been placed on the market in a revised form.

Coating color monitoring

The GAW Quality-Loop is the online-monitoringsystem for the control and recording of all qualityand production relevant characteristics concern-ing coating color for coated paper and carton-board in the coating-cycle.

The Quality-Loop is directly installed in the coat-ing unit and measures a partflow of the suppliedcoating color in the specific state which isprocessed on the coater. The modular construc-tion enables the specific adjustment to customers´wishes and demands.

The paramter temperature, density-, solids-, andgas content, redox-potential, pH factor and vis-cosity in connection with the shear rate from thelow to the highshear-area are measured onlineand are archived.

The controlling of the GAW Quality-Loop isbased on the AutomationX system through whicha smooth operation, an efficient alarm handling

and a reproducable documentation of the mea-sured value is guaranteed as trends.

Research project with Joanneum Research

The measuring methods for air content and vis-cosity were developed during a research project to-gether with the well-established Joanneum Researchinstitute in Graz. These methods thus representdownright new developments.

The measuring of the gas content is done via ul-trasound. The principle behind that method is thatsound is damped through media with fewer densi-ty more strongly than through media with higherdensity. If an ultrasound signal is sent through thecoating color, the received signal is getting weaker,the more gas inclusions exist in the coating color.The intensity of the received signal is therefore a di-rect measurement for the gas content.

The measurement of the viscosity is done via a slitnozzle which was designed specifically for this pur-pose. Before and after the slit nozzle, a compressiontransmitter is built in. If a liquid runs through the slitnozzle, a decrease in pressure develops as a con-sequence.

The difference in pressure is direct measurementfor the viscosity of the medium. In addition, this de-crease also depends on the flow velocity through theslit nozzle.

The GAW Quality-Loop is constructed to pump thecoating color through the measuring facilities inramp sequences, faster and slowlier again. The vis-cosity from the low- and highshear area can there-fore be measured directly in connection with theshear rate, and not at only one point like withotherviscosimeter tool for quality control.

The GAW Quality-Loop represents an excellent in-strument for the quality securing in the paper indus-try because of its compact structure, its user friend-liness and little maintenance.

It is not unlikely that the GAW Quality Loop willbie employed also in other industries for the controlof continuous production processes for liquid media.
