Description
Technical field
The present invention relates to a kind of resin degasser, specifically is a kind of vacuum lining form pressurization resin continuous degassing device ingenious, that degasifying effect is good that designs, and the invention also discloses the resin degas method that adopts this resin degasser simultaneously.
Background technology
Resin is generally used in the manufacturing process of composite element, as matrix material fiber is bonded together, and forms very high but the composite that density is lower of intensity.Resin should be filled the space between the fiber as matrix, between fiber, does not form the space, can make the intensity of fiber reach maximum.But; Resin is the bigger liquid of a kind of viscosity under nature, wherein can dissolve the air of certain proportion (2～3%), in use; Resin can mix with curing agent and takes place to become solid after the oxidation reaction, and this part is dissolved in the resin air and can from resin, separates out in solidification process.What the manufacture craft of large-scale composite material member adopted usually at present is the priming by vacuum mode; Mainly be with the need laying of fiber, be sealed in then in the vacuum diaphragm, being extracted into certain vacuum in the vacuum diaphragm according to member; Then resin is imported corpus fibrosum, fully with the whole member perfusion.In vacuum perfusion process; Because the formation of member forms in vacuum diaphragm; The air of separating out in the resin curing process can't have from the vacuum diaphragm derivation and in each position of member, and this part air can cause producing between the fiber space, and these spaces can make the stress of multiple material member concentrate on the gap; Cause the intensity of multiple material component partial to reduce, will the quality of multiple material member be produced serious influence.For this reason,, will greatly improve the quality of multiple material member before perfusion, strengthen the intensity of multiple material member if the air that can will be dissolved in the resin is just taken off.
But there is big difficulty in the resin degassing at present:
Resin before perfusion, needs and curing agent evenly mixes, and only after mixing, outgasing just can produce effect, otherwise one-component degassing back still can entrained air in mixed process.But after mixed with resin, resin and curing agent just begin reaction, and the time of leaving degasification process for is just more limited.
Because mixed resin will be solidified into solid; And must residual a certain amount of resin in the facility of the resin degassing; If untimely cull is cleared from facility, the resin of curing bring difficulty will for reusing of facility of the degassing, even degassing facility is scrapped.In view of above-mentioned two difficulties, in actual production, carry out the resin degassing and can't realize always, continuously resin being outgased especially on a large scale is used for perfusion then.
Summary of the invention

Also disclose the degas method that adopts above-mentioned vacuum lining form pressurization resin continuous degassing device among the present invention, these method concrete steps are following:
(1) cotton and the vacuum bag degassing tank formation vacuum lining form pressurization resin continuous degassing device of packing into of will breathing freely, then that degassing tank is airtight;
(2) open vacuum exhaust pipe; Open porting then degassing tank is vacuumized, vacuum bag is adsorbed on the degassing tank inwall through vacuumizing action, ventilative cotton between degassing tank inwall and vacuum bag; In this step, will open the vacuum exhaust pipe on the vacuum bag before degassing tank is vacuumized earlier, such step design is in order to prevent that vacuum bag from can not open fully; It is specific as follows: because the vacuum exhaust pipe on the vacuum bag is in open mode; When porting vacuumizes degassing tank; The bag wall and the degassing tank inwall of vacuum bag are fitted, and air gets into vacuum bag from vacuum exhaust pipe under the effect of pressure simultaneously, and vacuum bag is opened;
(3) resin inlet tube and resin outlet are closed, vacuum bag is vacuumized, vacuum bag is become vacuum state through vacuum exhaust pipe;
(4) keep vacuum exhaust pipe to be in the state of vacuumizing, open the resin inlet tube, resin gets in the vacuum bag, and the air that dissolves in the resin can be separated out in vacuum environment, and discharges through vacuum exhaust pipe, reaches the purpose of the resin degassing;
(5) close vacuum exhaust pipe and porting; Then the porting at degassing tank middle part is opened; Feed compressed air through porting to degassing tank, compressed air can not have the space of resin to shrivel on vacuum bag top, opens the resin outlet then; Under compressed-air actuated effect, the resin in the vacuum bag is extruded from the resin outlet and is left degassing tank;
(6) after the resin in the degassing tank is discharged from and finishes, close the resin outlet, return step then and carry out the degassing of next round resin.
Beneficial effect: vacuum lining form pressurization resin continuous degassing device provided by the invention and degas method thereof compared with prior art, have the following advantages:
Vacuum lining form pressurization resin continuous degassing device of the present invention, simple in structure, design ingenious, easy operating;
The degas method of employing said apparatus of the present invention, through having realized the degassing fully of resin under the action of air pressure, the method for the invention has realized the continuous degassing of resin simultaneously, has improved operating efficiency.
After using primary equipment, can the vacuum bag in the degassing tank be changed and carry out degassing work next time then, the consumable material of the degassing only is a vacuum bag, is that material cost or cost of labor are all very low, is suitable for industrial applications.
