1 Open House 2012 Color change time is money Dieter Rothe

2 Agenda Our problem down time and waste Master batch and flow channels Possible solutions Summary Page 2

3 Color change takes forever Why? The converter blames it to the head manufacturer Head manufacturer says it s the screw Machine manufacturer advices to check the parameters Others ask Is it the master batch? Meanwhile the problem goes on Page 3

4 Subject colored line in the product We have started to look into this! If a color change takes 4to 6 or 8 hours At a throughput of 200kg/h Color change once a week Per year 200hours and 10tons of resin wasted Page 4

5 Agenda Our problem down time and waste Master batch and flow channels Possible solutions Summary Page 5

6 Master batch Contains color pigments Carrier mostly LLDPE and LDPE Can be organic or inorganic Additives Or even both Have dispersin g aid, oil, wax Page 6

7 Good things to know about master batch Temperature stability can be e.g. 180 C 300 C! But this is only up to 5 min (EN12877) LLDPE as a carrier has a low melting point LDPE carrier is higher in melting point Both carriers are higher in MFI than HDPE So we have a different viscosity Batchers like to see an early melting for a good dispersion, but Contamination on the screw Page 7

8 Melt flow channel basics Always a laminar flow Turbulent flow would clean better Velocity in the center is high L Metal wall v 0 Velocity at the wall is almost ZERO High risk of deposits Color pigments will increase the risk Smaller Ø would increase the velocity v index : max Ø But also increase the pressure drop p 1 p 2 Page 8

9 Complete extrusion system Page 9

10 It all starts with the screw layout Color deposit in the melt channel Melt channel too large? Residence time too long Page 10

11 Key points of a screw Screw for the correct throughput min/max. Proper screw design Screw tip and mixing Page 11

12 Head and extruder adaptors Change from turbulent to laminar flow Change from ring channel into pipe Dimensions here are very important Too large, gives a high risk for deposits Too small, creates to much back pressure Ø Screw tip Solid melt Page 12

13 Head and extruder adaptors Change from turbulent to laminar flow Change from ring channel into pipe Dimensions here are very important Too large, gives a high risk for deposits Too small, creates to much back pressure Composition of the master batch? Ø Makes a big difference Screw tip Solid melt Page 13

14 Melt flow divider for a multi parisonhead Same requirements as the adaptors p in Streamlined and balanced design Adjust pressure drop and channels p 1 to p 6 should be equal e.g. 80 bar split 120kg/h 2x60kg/h Consider shear rate/velocity Deposit as in the adaptor will continue 6x20kg/h P1 P2 P3 P4 P5 P6 But different, due to flow channel split Page 14

15 Melt flow divider for a multi parisonhead Same requirements for the adaptors Pin Streamlined and balanced design Adjust pressure drop and channels split p 1 to p 6 should be equal e.g. 80 bar Consider shear rate/velocity Deposit as in the adaptor will continue Cooled down HDPE melt out of this manifold But different, due to flow channel split Reason why outer parisons take longer Page 15

16 Pinola head design Heart curved shape Top or side fed system For mono and multilayer Equal flow due to double heart curve Double Single Overlapping Page 16

17 Pinola head design Heart curved shape Top or side fed system For mono and multilayer Equal flow due to double heart curve Overlapping principle of Kautex No weak spots as at spider legs 3D Overlapping heart curved system of Kautex Maschinenbau Page 17

18 Pinola head design Heart curved shape Top or side fed system For mono and multilayer Equal flow due to double heart curve Overlapping principle of Kautex No weak spots as at spider legs But longer color change why? Join line of the melt flow is visibly 2D Overlapping heart curved system of Kautex Maschinenbau Page 18

19 The heart curve and the join line All heart curves have the same phenomenon Color deposits from the adaptors/flow channels stay accumulated visibly at the join line Joining point at the parison and at the bottle Page 19

20 The heart curve and the join line All heart curves have the same phenomenon Color deposits from the adaptors/flow channels stay accumulated visibly at the join line Joining point at the parison and at the bottle Very sensitive are effect pigments like pearl Misaligned / optical refraction Source: Merck Page 20

21 Torpedo head Spider leg design: 2 and more legs Just one channel or two (inner/outer) Legs can leave weak spots at a low MFI For mono layer only Best in color change, central flow e.g. 30 min 4 x 4 spider legs Color deposit is still the same But is not so much visible (360 ) 2 spider legs Page 21

31 Agenda Our problem down time and waste Master batch and flow channels Possible solutions Summary Page 31

32 Summary Pigment and master batch formulation is important Keep adaptors short Select your optimum support for a faster color change Screw and flow channels need to match the throughput Choose the best suitable head design for your application Improving color change stays an important subject, and we are continuously working on this.
