Technical field
It is especially a kind of de- using ultrasound examination resin and curing agent the present invention relates to wind electricity blade manufacturing technology field
The method of air bubble content during bubble.
Background technique
Wind electricity blade is shell structure made of a kind of composite material, divides three root, shell, web parts in structure,
For wind-power electricity generation.To obtain more powerful, more regular wind field environment, the installation of blower is gone to via land away from seashore
The increasingly remoter sea of line, this transformation propose increasingly higher demands to the safety of wind electricity blade, reliability.And wind-powered electricity generation leaf
In the scale manufacturing process of piece, occur that wind electricity blade is caused to whiten to form the defect of various grades due to bubble coalescence often,
Though these defects repair in factory, its hidden danger buried may cause blower and be not normally functioning, and even result in wind-powered electricity generation
Thus blade rejection brings huge maintenance cost or other economic losses to blade factory, main engine plants.
The reason of being analyzed through field investigation, leading to bubble coalescence in wind electricity blade production process first is that due to wind electricity blade
Main raw material(s) epoxy resin and its curing agent itself or its mixed process in there is or generate bubble, though produced on-site process
In deaeration processing can be carried out to one-component and mixed resin, and artificial judgment whether there is bubble, but mixed tree
Microbubble naked eyes in rouge are difficult to.It is still at present to be in for the detection of matrix resin air bubble content in wind electricity blade industry
Blank stage has a kind of method using ultrasound examination bubble, this method is not by connecting through inspection information in medical industry
Ultrasonic wave is captured continuously, determines to whether there is bubble in transfusion system, but there are bubbles in raw material system known to us
In the case of, what this method cannot be qualitative or quantitative judges the content of bubble, therefore is badly in need of a kind of simple, reliable method, realizes
The content of bubble in resin after mixing quickly is detected at the scene.

Specific embodiment
Embodiment one:
Fig. 1 to Fig. 2 is please referred to, a method of it is first using air bubble content in ultrasound examination resin and curing agent de-aeration
First, the air bubble content by detection pure water under static state, obtains energy reference value.Ultrasonic unit is connected, is adopted
After being fixed probe with tooling, probe is placed in pure water.Pay attention to not thering is particle, impurity or other pollutants in water.It opens
Ultrasonic unit and its data acquisition relevant device and software are opened, is kept for tooling static a period of time, then adjust tooling position, then
Keep the static acquisition standard energy figure of tooling.Stable data can be obtained when probe is fixed on a certain position, but adjust probe position
Energy value has larger fluctuation when setting.The reason is that the detection method location sensitive, the reason of belonging to the detection method itself.Make to visit
Head is at a distance of being required preset distance appropriate, and under the preset distance, the ceiling capacity that ultrasonic unit can capture is about
300000(mV*ms)/S.It is carried when multinomial in Fig. 1 is original system machine forming curves, is that waveform is more with certain
Item formula is converted to curve representated by multinomial in Fig. 1.
It is then detected that the air bubble content of resin and/or curing agent solution.It is specific include again it is following step by step:
1, ultrasonic unit is connected；
2, probe placement.Two probes of ultrasonic unit are fixed in tooling, and ensure that two probes are opposite.By ultrasonic wave
The probe of device is placed in epoxy resin and its curing agent mixed liquor, it is ensured that spacing of popping one's head in detection process is stable and does not shake.
This kind of laying method should be noted that protection probe is not contaminated.
3, the energy diagram of epoxy resin and its curing agent is obtained.The probe being fixed in tooling is put into need in solution
Notice that protection probe is not contaminated.Open ultrasonic unit and its data acquisition relevant device and software.Open ultrasonic unit
And its data acquire relevant device and software, detect air bubble content in epoxy resin and its curing agent.
4, data collection and analysis.Ultrasound examination after certain brand epoxy resin and its curing agent mixing in de-aeration
Curve (ultrasound examination energy curve figure in normal capacity resin and curing agent mixed liquor de-aeration), as shown in Figure 1.In I
Air bubble content is lower and lower in stage de-aeration, and the energy that ultrasonic wave passes through glue decaying is fewer and fewer, thus energy curve
It is higher and higher；Work as arrivalStage, ultrasonic energy curve reach acme can tend towards stability (i.e. near the value of peak it is a certain compared with
Fluctuated between narrow numberical range), illustrate the content of bubble in glue (epoxy resin and curing agent mixed liquor) to reach current pumping
Minimum under gaseity.Checked the stabilization sub stage by energy curve (Stage) whether the energy that is captured be higher than 300000
(mV*ms/S), determine whether mixed liquor (epoxy resin and curing agent mixed liquor) can be used for producing.When ultrasonic unit is captured
Energy be higher than 300000 (mV*ms/S), the epoxy resin and its curing agent mixed liquor can be used for producing.Standard is such as not achieved,
Replaceable air-extractor as needed increases pumping strength, continues to carry out deaeration processing to resin and curing agent mixed liquor, directly
Until reaching standard.

Sample generate reflection with reflect and submit to the similar reflection of geometric optics, the law of refraction, according to ultrasonic wave in gas, liquid, solid
Absorption and decaying in body is different, is emitted using transmission beam method come detecting ultrasonic wave and whether receive between energy converter has gas to deposit
So that air bubble content detection device be made.
Air bubble content in glue is detected, is equal to the ultrasonic examination of continuous media, the bubble in glue can be regarded as
The internal flaw of liquid, when zero defect in liquid, ultrasonic wave passes through the energy attenuation very little of liquid, and energy converter receives super
Acoustic wave energy is stronger；When there is bubble, ultrasonic wave major part energy is actually taken up by gas, the energy that at this moment ultrasonic transducer receives
Measure very little.
Ultrasonic equipment emits and receives ultrasonic wave, is characterized in glue by receiving the energy size that energy converter receives
Air bubble content.Resin bubble is more, and the loss that energy penetrates resin is more, and final received energy is with regard to smaller, on software
The energy value of display is lower.
Ultrasonic wave in pure water can be stablized the energy of capture as energy base by basic bubble-free under stationary state in pure water
It is available then to determine that the air bubble content in resin has reached when the energy for stablizing capture in resin is higher than energy reference value for quasi- value
