LIST OF TECHNICAL EQUIPMENT
We perform the zinc coating of iron parts in suspension as well as in drum production lines
| Centrifuge "RAPIDE" of SC 70 Vx KFEC2 type |
- The centrifuge with removable drum and pull-out central cone discharging.
- Three-point suspension.
- Driven by rotation of side-located motor connected with the frequency converter.
| Drum diameter | 675 mm |
| Drum height | 365 mm |
| Drum speed adjustable to | 750 ot./min |
| Net capacity of drum | 60 litrů |
| Maximum permitted content | 100 kg |
| Output per hour | 4/6 šarží |
| Machine weight | 700 kg |
Highly resistant drum carrier made of carbon steel, which carries the removable drum of structural steel, which consists of two parts and is discharged by vertical shift.
Alternating speed AC (SA-KC) or intermittent speed (SC-KC) together with the cone-shaped drum allow a better spinning of components, in which otherwise the liquid might retain (such as blind holes).
| Suspension line - zinc alloy (Fe/ZnFe) + black passivation |
- Zinc alloy Zn/Fe (0.4-0.8 %) + black passivation (chromate)
- Surface treatment with increased corrosion resistance in comparison with Zn
- Zinc alloy with subsequent additional treatment
- Zinc alloy Fe/ZnFe (0.5-0.8%) + black passivation (with Cr 6+ )
- Enhanced corrosion resistance of the coating: up to 720 hours without red corrosion
- Zinc alloy Fe/ZnFe (0.5-0.8%) + black passivation (without Cr 6+ ) + sealing
- Enhanced corrosion resistance of the coating: up to 480 hours without red corrosion
- Dip tank dimensions 1,600 x 600 x 800 mm (length x width x height)
| Suspension line - yellow and blue chromate + high-thickness and thin passivation |
- Alkaline zinc coating with subsequent additional treatment
- Passivation with subsequent sealing by Hydroclear
- Dip tank dimensions 1,600 x 600 x 800 mm (length x width x height)
Yellow chromate
- Zn + yellow chromate (with Cr 6+ ) c/w or w/o sealing
High-thickness passivation and blue chromate
- Zn + blue chromate (without Cr 6+ ) c/w or w/o sealing
- Zn + high-thickness passivation (without Cr 6+ ) c/w or w/o sealing
| Drum line - yellow and blue chromate + high-thickness passivation |
Yellow chromate
- Slightly acid zinc coating with subsequent additional treatment
- Passivation with subsequent sealing by Hydroclear
- Zn + yellow chromate (with Cr 6+ ) c/w or w/o sealing
High-thickness passivation and blue chromate
- Slightly acid zinc coating with subsequent additional treatment
- Passivation with subsequent sealing by Hydroclear
- Zn + blue chromate (without Cr 6+ ) c/w or w/o sealing
- Zn + thick passivation (without Cr 6+ ) c/w or w/o sealing
| Verification of the zinc coating - traceability |
- The software equipment of the zinc coating line makes it possible to control and check the current process parameters as well as to retrieve and print out the desired parameters.
| Corrosion resistance tests of zinc coatings |
- Test with condensed water containing NaCl salt solution - SS DIN 50 021
- Test with condensed water containing SO2 - DIN 50 018
- Test with condensed water in variable climate conditions - DIN 50 017
