Detailed description of the invention
Be further described inventing the technical scheme related to below in conjunction with exemplary embodiments, but the present invention is not limited only to embodiment.B component formula in the following example is mass fraction.
Embodiment one
Component A:
NCO% is the MDI semi-prepolymer 100 of 20.0%
B component:
By above-mentioned formula, A, B component are respectively charged in A, B material cylinder of portable non-lethal viscous ball emitter, be cured time and transmitting range test, and A, B component mixture are poured in the thick mould of 2mm by portable non-lethal viscous ball emitter, the elastomer test piece of 2mm is formed after solidification, carry out hot strength test, test result is in table 1.
Table 1
The technical scheme that the two component viscous bullet material transmitters being 1:1 for drive of high-pressure gas mode, volume ratio the present invention relates in detail.
The basic structure of two component viscous ball emitter is as accompanying drawing 1 schematic diagram.Comprise power source 1, with piston 5 two component material cylinders 2, two ends are respectively with the tube connector of ring flange and loose joint, blender 3 and nozzle 4.
Power source 1 comprises high-pressure air source, control valve and twin shaft cylinder.High-pressure air source is 2L gas cylinder, and the gas pressure of output is set in 0.8MPa, using ball valve as control valve by pressure-reducing valve by bottled pressure-air.
Two component material cylinders 2 are the cylinder block of a pair length 200mm, internal diameter 50mm, matching circular piston 5.
Blender 3 is length 140mm, internal diameter 50mm, the spiral plate type static mixer of the flanged dish in two ends.
Nozzle 4 for one end be the circular cone convergence type nozzle of ring flange, the diameter end of convergence type nozzle is 50mm, and the other end is 5mm, and the reducing corner of nozzle inside diameter is round-corner transition, and radius of corner is 240mm, and structure is as shown in Figure 2.
Be connected with blender 3 with the discharging gate of ring flange by two component material cylinder 2 by loose joint with tube connector, by ring flange, blender 3 be connected with nozzle 4, the portable viscous ball emitter of the two components obtaining the present invention relates to.
This transmitter is applicable to two component viscous ammunitions transmittings that volume ratio is 1:1, and range can reach 8 meters.
Preferably, nozzle adopts pressurized construction (pressurized nozzle structure as shown in Figure 3), and air supply channel 7 is 13 ° with the angle α of nozzle 4 tapping channel.To using same medicament, jet length improves more than 10%.
Another kind of preferred version, arranges cleaning device 9 before mixing chamber, and cleaning device 9 connects two component material cylinder 2 and blender 3 (syndeton as shown in Figure 5) by duplex three-way sphere valve 10, realizes expecting that cylinder and nozzle repeatedly use.
Fig. 6 gives the structural representation of two component viscous ball emitters of preferred version, and this transmitter, while having good launching effect, is convenient to cleaning, and material cylinder and nozzle repeatedly use.
