Following experimental example is used to further specify this utility model, but is not limited to this utility model.
The contrast of the relative vertical bar rosin joint of experimental example 1 two-chamber bag bag type radian rosin joint effect
The relative vertical bar rosin joint of radian rosin joint, length increases than each chamber periphery of bag, and the bag dynamics is disperseed more when dividing, and rosin joint each point dynamics alleviates relatively.
Crucial as multi-chamber-bag is exactly rosin joint partly, for vertical bar rosin joint defective is exactly: open effect in order to guarantee the user.The rosin joint dynamics is overweight will to cause the user to be difficult to open rosin joint in use.This product rosin joint dynamics kicks the beam and will cause rosin joint to cause stressed straight right unlatching the in rosin joint bar middle part in producing postorder work with in the transportation.And this vertical bar rosin joint do not have any opening point, and reality is the weakest for that welding of whole piece rosin joint bar when opening, and that could be understood and is opened at first.
And for radian rosin joint bar: this rosin joint bar has been made the curved profile of a R5mm～R20mm apart from the 60mm scope of bag limit.This curved profile is an opening point: it is heavier relatively directly to weld the actual arc rosin joint of rosin joint bar bar welding dynamics.So just avoid this product rosin joint dynamics to kick the beam and in producing postorder work with in the transportation, to have caused the stressed image of opening naturally in rosin joint bar middle part.This radian opening point welding dynamics is all than straight weldering rosin joint bar rosin joint welding dynamics height, and refers to need the bag doubling is remained in the opening point direction with medicinal liquid when opening, and adopts the hands support can open the rosin joint bar to pressing down to exert pressure to the bag bag again.
Concrete straight welding rod and the contrast of arc rosin joint bar unlatching dynamics: normally divide the band actual dynamics of the withstand voltage dynamics of arc rosin joint bar (can find out that thus can tolerate higher impact rosin joint in transportation can not open naturally yet) under the situation than straight weldering rosin joint bar high 40%～60%, and when opening the rosin joint bar, refer to need the bag doubling is all remained in the opening point direction with medicinal liquid, adopt the hands support can open rosin joint bar (and this unlatching dynamics only need less than 60% dynamics of the straight withstand voltage unlatching dynamics of welding rod) again to pressing down to exert pressure to the bag bag.
Simulate welding effect test method: the sample (directly welding each 3000 in rosin joint and radian rosin joint sample) after the simulate (travel speed and distance: the speed of a motor vehicle of simulating 40 kilometers/hour is travelled on dirt road or the broken stone road 1000 kilometers continuously being equivalent to) is taken out, after checking that outer package does not have leakage and breakage, take complex pocket apart, sample is placed on the exsiccant paper, apply the intrinsic pressure of 20kpa in the smooth part of bag by bag, keep about 15s, seam should not have leakage, bag crack-free.Sample thief repeats above experiment three times in addition, and the result is as follows:
