2-COMPONENT EXTRUSION AND DOTS (98:2)
From city areas to urban and interurban roads, the BM 2700 can handle both smaller jobs and longer road stretches.The BM 2700 is an agile machine with excellent load abilities. It allows for thermoplastic capacities up to 360 liters, 2- component or Cold Paint capacities of 440 liters and for two colors cold paint also 2 x 220 liters.Equipped with the new generation of Borum’s LineMaster computer, operating the machine is easy and convenient.The application equipment can be set to execute lines in widths between 10-30 cm. The equipment on this machine may be used for the application of flat lines and profiled dots.
Line types that can be applied with this equipment
Pressurized material tank and filters in stainless steel for water and ammonium based paints.
Option for black steel tanks.
The material tank has a filling system with two filling holes. This makes the filling process very easy to manage.
Driven by hydraulic motor and with manually operated reversing valve.
Being equipped with an internal mixer for mixing of the paint and hardener and efficient cleaning system that is easily triggered from the machine's computer, the Borum 2-component cold plastic equipment is constructed to provide high-quality road markings.
THE BORUM 2-COMPONENT COLD PLASTIC EQUIPMENT (LOW PRESSURE SYSTEM) CONSISTS OF:
1. Separate material tanks for:
- Solvent for cleaning
2. Feeder system with:
- Pump system that ensures the 98:2 ratio for the paint and hardener
- Mix for blending the paint and the hardener. The mixing of the material is don internally, so it is not affected by external factors as wind etc., as for external mixing
-Pressure valves digitally controlled by Borum LineMaster computer. No need for mechanical adjustment while marking
The Borum Vario Retainer provides a unique possibility to interchange between applications in a very short time, with very few standard tools. When the work is done, the retainer and application equipment can be easily stowed under the machine.The retainer makes it possible to use all application equipment in different positions on the machine.
Easily slidable from side to side for an optimal working position. Ground distance is maintained by retainer wheel to ensure a constant road marking width.
The pump system consists of a lobe type paint pump and gear type pump for hardener. The two pumps are driven by one hydraulic motor via chain and variable gearbox securing the 98:2 relation between paint and hardener.
The system is also equipped with a controller for performing the flushing of gun(s) and mixer.
For making 2-component dotted lines in all standard line widths.
The Borum 2-component DOT is a flexible system of building blocks, which makes it possible to put together exactly the required application size.
The line width can be 10-30 cm, the line thickness can be from 1,5 to 5 mm, and the gap between the dots is 17 mm. Dot thickness is usually around 3-4 mm.
The marking speed can be 4-5 km/h depending on the conditions, e.g. material, dot size, operator's experience, etc.
DOT basic module includes 6 rows of DOTs. With a built-in mixer and pneumatic valves for paint, hardener and cleaning solvent, all controlled from the LineMaster.
Maximum of 18 dots across the head, separate cleaning extension is needed for dot heads wider than 13 dots.
Recommended quantity dots/m 15-20, controlled in the LineMaster computer. Recommended paint viscosity > 8500 cp.
The extruder is ordered for the specific line width. The line width can be 10-30 cm and the line thickness can be set to 1-3 mm (ribs/profiles can be up to 10mm depending on the material).
The extruder head is provided with a quick connector to the mixer head for easy exchange of equipment. The extruder is also provided with a pneumatic cylinder with cleaning arrangement.
The extruder is ordered for the specific line width. Available line widths are 10, 12, 15, 17, 20, 22, 24, 25, 30 (4, 5, 6, 7, 8, 8.5, 9, 9.5, 10, 12 inch.) Provided with quick connector to the mixer head for easy exchange of head.
Usual marking speed is between 2-6 km/h depending on work and weather conditions, operator experience, etc. Faster application speeds can be achieved.
Recommended paint viscosity for extruded lines is higher than 6500 cp and for ribs is higher than 8500 cp.
Fitting and exchanging the Borum 2-Component Extruder with other 2-component equipment, such as Dot or Agglomerate, can be done in less than 2 minutes, without the use of tools.
The cleaning system is formed by a solvent tank for cleaning of mixer-head, hoses and paint guns. The system is activated via the Borum LineMaster computer. The cleaning process is an automated preset sequence ensuring the correct valves are opening/closing.
36L pressure solvent tank for cleaning of mixer-head, hoses and paint guns.
Stainless steel, max 8.5 bar.
NB! When working with 2-component whenever the application is stopped, application equipment has to be cleaned from the cold plastic mixture within a few minutes.
The Borum LineMaster control unit is an easy way of setting and controlling your line marking jobs. The LineMaster is attached to the operator's section of the machine and gives you full control of all your line marking tasks, from line application and pre-marking to reporting and invoicing.
It is possible to store up to 99 different line types, and to arrange these in up to 30 different marking programs. You are also able to pre-set line widths, line types and different combinations to have them ready for marking, and can instantly adjust them on the go.
Furthermore, you are able to view the status of various parts of the machine (e.g. compressor) on the computer screen that will help with correctly maintaining the machine and avoiding break downs.
