THERMOPLASTIC EXTRUSION AND RIB LINE APPLICATION
From city areas to urban and interurban roads, the Borum Master 2000 can handle both smaller jobs and longer road stretches.
The BM 2000 T RL is an agile machine with excellent load abilities and a turning radius of only 3,2 m. It allows for material tank capacity of 265 L.
The BM 2000 has a one-seat slidable drive and operator section for flexible working on the left or right side.
The thermoplastic Borum extruder can apply lines of 5 – 40 cm width depending on the set-up. The extruder may be used for the application of various types of plain and profiled lines, single and double lines of different widths, as well as for simultaneous application of continuous and interrupted lines.
The Rib line equipment comes with fixed line widths up to 20 cm.
Line types that can be applied with this equipment
Non-pressurized thermoplastic tank indirectly heated via heat transfer oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically.
Diesel burner system for heating of the thermal oil (and thermoplastic). Propane burner available on demand.
Vertical agitator (mixer)
With hydraulic transmission. Heated center pipe for efficient uniform temperature control. Perfect melting & homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.
The Rib Line application equipment can apply flat lines, ribs (longflex), and a combination of ribs on line in one pass.
With this type of screed application, the box is dragged with constant contact to the surface. The contact points determine the line width. The material pressure is by gravity only and this is how the material is poured in the marking box. The material coming out of the box will fill up any holes, pores, or other types of road imperfections. This means that material consumption will depend on the road surface.
The Rib Line equipment is mounted directly on the side of the material tank.
The equipment is constructed with one main application box. If you do not need to switch the line widths often, you have the option to only change the application opening based on your width requirements instead of the whole box! This makes the application equipment more cost-efficient!
The Borum thermoplastic Rib Line application equipment is available in the following widths: 10, 12, 15, 20 cm.
The total height of line with rib is usually between 8 to 12 mm. The lines are recommended to be as thin as possible when combined with ribs (approx. 1,5 - 2 mm).
The usual application speed for applying ribs over a flat line is 1-3 km/h, while for screed application of flat lines it is up to 5 km/h.
The equipment is also supplied with a laser that constantly measures the material level in the application box. If the material level becomes lower than 50%, the application box will be automatically refilled.
Thermoplastic material has a long-life duration with high retro-reflectivity capabilities due to being able to pre-mix glass beads in the material. Thermoplastic markings cure quickly and adhere strongly to the road surface. Generally, thermoplastic is recommended for areas with high traffic density and/or areas with low lighting as e.g. highways.
The rib line equipment is a cost-efficient marking equipment with reduced investments cost for thermoplastic application. This is a good solution if you are only going to work with flat markings and rib line application.
An alternative to the rib line equipment is the Borum thermoplastic extruder with which you can apply various flat and profiled markings. The extruder also uses a different application method by extruding an even layer of material on the road surface. Therefore, if the surface is rough or uneven, the line is the same as it follows the imperfections. In other words, the material consumption will be predictable according to the adjustments and will not be as influenced by the type and condition of the road surface.
The working principle of the extruder lies in the extrusion of the ready hot thermoplastic material through the extruder valves onto the road surface. Glass beads can be automatically applied. The thickness of the line is controlled by the slot gap and the speed of the machine, coupled to the thermoplastic feed rate.
Thermoplastic extruder set-up ranging from 30-50 cm total line width, built-up with 5 cm standard valves (alternative valve dimensions in the range of 4-10 cm for alternative line widths).
Hot-oil heated equipment for optimal performance.
Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven.
Pneumatic lifting cylinder for up/down function, operation controlled from operator’s seat.
The shutters do not touch the high tensile steel drum and therefore the lifetime is long.
Pneumatically controlled quick cleaning function for the removal of solids left in the extrusion slots can be activated while extrusion is in process.
Continuous circulation of the thermoplastic inside the equipment. This avoids settling and catching of solid parts and prevents unecessary wear of
The application speed goes up to 8-10 km/h. Speed-dependent settings possible.
The transport of material from tank to extruder head is done by a hydraulically driven screw pump, which is electronically controlled. The screw pump has a permanent thermoplastic recirculation system which ensures a constant flow past the in-active extrusion valves, keeping these clean and ready for opening.
Build-in pressure regulating system ensures that line width and thickness does not change no matter the number of the shutters involved in the current marking assignment.
Thermoplastic is a durable material that cures quickly and adheres strongly to the road surface. It can be used for applications of both flat lines (also known as type 1 lines) or of thick profiled lines and markings (also known as type 2 lines).
This type o material is used on various types of roads, but you will often see it on highways or motorways as it can outstand high traffic density, it has a high visibility at night and during wet conditions and glass beads can be mixed in for further enhancing visibility.
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, colours and 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.
Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. It can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of layer.
