The present invention can also effectively solve some product qualities and require highlyer, and the glass fibre wellability in the laying is poor, and the laying structure is thicker, and possible thickness is also inhomogeneous, problem that the poor and resin viscosity of sandwich material water conservancy diversion is large etc.
Description of drawings:
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of filling system among the present invention.
Fig. 2 is the flow chart of method for filling among the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
The present invention provides new technical scheme in order to solve the existing existing defective of vacuum perfusion process.
Vacuum cycle filling system at first provided by the invention is as shown in Figure 1:
It comprises that waiting to pour into mould 1 to be poured into, storage device 2, vavuum pump 3,4, material-pumping tube 5, the second vacuum takes out pipe the 6 and first vacuum and take out pipe 7.
The first vacuum is taken out pipe the 7 and second vacuum and is taken out pipe 6 and connect respectively vavuum pump 3,4 and provide the power of operation for whole system.The first vacuum is taken out pipe 7 and is connected vacuum and takes out the extraction end that pipe 6 connects respectively mould 1 to be poured into, and the second vacuum is taken out pipe and 6 also is linked into storage device 2, this storage device 2 connects the suction end of mould 1 to be poured into by material-pumping tube 5, will form the loop of a circumfusion.
The second vacuum is taken out the vavuum pump 4 that connects on the pipe 6 can provide a controlled power source for the pouring material circumfusion.
The first vacuum is taken out vavuum pump 3 that pipe connects on 7 and can be extracted air in the mould 1 to be poured into out and make laying in the mould 1 to be poured into through for the first time perfusion of resin.
The circumfusion method of the circumfusion system that obtains based on such scheme as shown in Figure 2, it may further comprise the steps:
The first step, during use, lay wait the laying of pouring into mould 1, whole vacuum cycle filling system complete after, in storage device 2, add pouring material; During perfusion, make the second vacuum take out the vavuum pump 4 that connects on the pipe 6 and be in out-of-work state, and close the second vacuum and take out pipe 6, simultaneously so that vavuum pump 3 is in the state of work, open the first vacuum and take out pipe 7, take out pipe 7 beginnings by the first vacuum and outwards take out the air of mould to be poured into the inside.
Second step, the pressure differential that rear air produces owing to bleed, pouring material is extracted into first the laying of mould 1 to be poured into by material-pumping tube 5 from storage device 2, after perfusion after a while, pouring material slowly arrives the extraction end from the suction end of mould 1 to be poured into, when pouring material is about to reach the extraction end, opening installation is taken out the vavuum pump 4 of managing on 6 in the second vacuum, close simultaneously vavuum pump 3 and the first vacuum and take out pipe 7, make like this and take out pipe from 1 li pouring material of releasing of mould to be poured into by the second vacuum and 6 pass back into the storage device 2.
The 3rd step, next pass through the continuous firing of vavuum pump 4, pouring material will be constantly taken out pipe 6 by material-pumping tube 5, mould to be poured into 1 and the second vacuum and is entered and carry out circumfusion in the storage device 2, and the number of times of circulation can decide according to the laying structure of concrete one product requirement, product, the viscosity of pouring material etc.If the glass fibre wellability in the laying is poor, the laying structure is thicker, and possible thickness is also inhomogeneous, and the sandwich material water conservancy diversion is poor, and the number of times that we can increase circumfusion improves the quality of product.
We it should be noted that and consider that circumfusion needs the more time, so can come curing agent content in the flexible modulation storage device 2 according to the time length of perfusion in perfusion usually.Thereby the content that can reduce in case of necessity curing agent in the process of circumfusion by adding pouring material prolongs the pouring material gel time.
