Description
Technical field
What the present invention relates to that a kind of large-scale composite material spare adopts the priming by vacuum glue makes the bubble defoaming method, and what relate in particular to wind power generation blade perfusion glue makes the bubble defoaming method.
Background technology
Because vacuum perfusion process relative traditional handicraft when composite material forming is clean and pollute littlely, manufactures in the process at wind power generation blade in the world at present, generally adopts the vacuum infusion molding technology.Blade production at first is laid on the fiber laying in the mould according to designing requirement, then mould is vacuumized, and prefabricated exemplar is vacuumized, and utilizes negative pressure of vacuum to pour into glue with low viscosity and fills whole corpus fibrosum.It is huge to be used for perfusion glue consumption when blade is produced, 1.5MW blade when perfusion a slice need glue to reach 2 tons, play fast glue so usually adopt mixing machine, before playing glue resin and curing agent are mixed, mixed glue body clarification naked eyes are without obvious bubble, and viscosity is generally at 200mmPa.s after mixing.Conventional method has two kinds: a kind of slow glue of beating directly pours into, another kind of glue use vacuum defoamation method to getting, but the deaeration time is long, and deaeration efficient is low and deaeration is incomplete, still has a large amount of bubbles to remain in the bottling body in the blade even the glue after the process deaeration is filled into.It is huge that blade is produced the glue consumption, and long-time deaeration inefficiency can waste time and disconnected glue occur in the filling process and have influence on product quality, and several secondary moulds of workshop can only be equipped with many vacuum defoamation equipment when producing simultaneously.The glue that conventional method is got directly is filled into housing and the general glue that carries out after the vacuum defoamation and often pours into to the blade and can produce a large amount of bubbles at runner place and flow-guiding screen edge and gather; the blade inner surface exists because bubble gathers the bubble inclusion defect that forms white in a large number, and especially the crossbeam bottom has a large amount of bubble coalescence.Reason is to contain a large amount of micron-sized bubbles in the glue that mixes out of mixing machine, and naked eyes can't be observed, and gelatin viscosity is large, life cycle short (glue of getting will be finished in 30min).So common in beating the glue process control Bubble formation or vacuum defoamation all can't in the time remove the microvesicle in the glue at 15min, the corpus fibrosum of vacuum debulk can liken porous media to when perfusion, a large amount of micro-bubbles are mixed in the corpus fibrosum by the fracture filtration of corpus fibrosum, turn white so that produce in the blade shell, the defective that this kind phenomenon causes has a strong impact on mechanical property and the fatigue behaviour of blade.
When playing glue, use the special gluing equipment of beating for adapting to rhythm of production.Generally, in beating the glue process, be divided into for three steps:
The first step is opened mixing machine glue is circulated, is mixed;
Second step is slowly squeezed into glue in the glue bucket along the bucket wall;
The 3rd step was put into the blade mold limit with the glue of accomplishing fluently, and by negative pressure of vacuum glue was circulated in the blade shell.
Owing to do not have air to bring into during the mixed glue of adhesive supplier, be to carry bubble in resin and the system of curing agent own so contain bubble in the glue, air pocket can not form when mixing, micro-bubble in the colloid is because the little buoyancy of volume is also very little, it is very large to add gelatin viscosity, so that micro-bubble is difficult to remove, wind electricity blade perfusion glue is the bi-component glue, resin with just begin reaction after curing agent contacts, so glue has the restriction on strict service time, usually will be after playing glue use up among the 30min.Owing to follow exothermic heat of reaction and viscosity rise, single barrel of adhesive liquid quantity is larger, and service time will be shorter, and deaeration must have strict time restriction General Requirements to finish deaeration in 15min.Existing defoaming method is difficult to reach requirement, therefore need to be improved this.
Summary of the invention
