THERMOPLASTIC SPRAY APPLICATION (PRESSURIZED)
From city areas to urban and interurban roads, the BM 2700 can handle both smaller jobs and longer road stretches.Equipped with Borum LineMaster computer, operating the machine is easy and convenient.The BM 2700 has a one-seat slidable drive and operator section for flexible working on the left or right side. Easy access and servicing of the machine through large doors to the engine room. The Borum spray plastic equipment on the BM 2700 SP can apply lines of up to 40cm (~50cm) width, depending on the set-up. The equipment may be used for the application of plain lines, single and double lines of different widths, as well as for simultaneous application of continuous and interrupted lines.
Line types that can be applied with this equipment
Pressurized tank indirectly heated via thermal 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 and homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.
Advantages when using a pressurized tank for spray:
The line thickness is affected by the machine speed, this is useful for applying thicker lines in curves and areas with higher wear and tear levels.
The maintenance for the pressure tank is minimal compared to the thermoplastic spray pump system.
Sliding retainer frame, upon which 1-3 spray guns and 1-3 bead guns can be attached. Easy slidable from side to side for an optimal working position. Ground distance is maintained by retainer wheels hereby ensuring a constant road marking width.
Lifting of retainer from operators seat is done using a hydraulic cylinder.
All material pipes are oil-jacketed and insulated to maintain an ideal material temperature.
Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven.
Line thickness is typically between 0.75 mm to 1.5 mm.
Marking speed up to 15 km/h depending on the work conditions, operator, etc.
Automatic high-capacity spray plastic gun. Consists of an oil jacketed gun body and a pneumatic cylinder. Possibility to apply line widths ranging from 10 - 20 cm depending on line thickness, work conditions, application speed and layer thickness. As an alternative, we offer a narrow nozzle, which can spray 5-15 cm with one gun. Optional narrow nozzle size of 3 mm or wide nozzle size of 7 mm.
The guns are mounted on a sliding retainer frame, on which 1-3 spray guns and 1-3 bead guns are attached. Easily slidable from side to side for an optimal working position. Ground distance is maintained by retainer wheels to ensure a constant road marking width. All material pipes are oil-jacketed and insulated to maintain an ideal material temperature. Lifting of retainer from operators seat using a hydraulic cylinder.
Due to the equipment working via a pressure vessel, it is very simple and easy to use as the pressure in the vessel is the same as the pressure in the application. Furthermore, the tank requires very little maintenance.
Thermoplastic spray markings are a cost-efficient solution as the applied lines do not require as much material as extruded profiled markings. Furthermore, this type of material forms a uniform application that is more durable and dries faster compared to cold paint applications.
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.
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.
