Description

A kind of measurement mechanism for imbibition capability of film object and measuring method thereof
Technical field
The present invention relates generally to material properties test technical field, particularly relates to a kind of measurement mechanism for imbibition capability of film object and measuring method thereof.
Background technology
Along with the continuous progress of science and technology, various new material arises at the historic moment, and the understanding for material different aspect characteristic is also gradually improved, and this it is also proposed higher requirement to measuring technique.
Imbibition ability for material is tested, conventional method is that the method by soaking is carried out, namely measure by measuring object to immerse before and after liquid of poor quality, but such method is Powdered to some, the material of block shape is more applicable, error is less.But only there is its error of several millimeter even film type material of several microns will be much larger for thickness, because the general density of such material is less than normal, and due to thickness little, immerse in liquid and take out again after imbibition, in regular air, during liquid storage, compole is short, accurately cannot obtain the quality after imbibition moment, and cause very large measuring error.
For the diaphragm paper used in lithium ion battery manufacture field, the imbibition ability of barrier film decides the quality of battery, therefore be the key index that lithium battery starting material are selected always, but its thickness generally only has tens to tens microns, adopt conventional immersion method, the barrier film after immersion liquid in atmosphere, liquid storage capacity is very poor, electrolytic solution evaporates rapidly, become dry, and accurately cannot measure quality after immersion liquid, causes the judgement that provides inaccurate.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of device that can accurately measure imbibition capability of film object.
The present invention is achieved by the following technical solutions:
A kind of imbibition capability of film object measurement mechanism, include the seal case that top seal is provided with suspension type balance, the loading hook of described balance hangs in seal box, hook hangs with article carrying container, fit tightly bottom described seal case on a liquid storage box, be communicated with by a valve one between casing with liquid storage box, seal case middle and lower part is surrounded by protective device together with liquid storage box periphery, described protective device is made up of insulation material, described seal box side is provided with through hole, through hole is connected with pipeline, the pipeline other end is connected with vacuum pump, valve two is installed in the middle part of pipeline, described seal box side is provided with valve three, atomizing ejecting device can be installed near seal case side by described valve three place.
Based on a kind of imbibition capability of film object measurement mechanism, its measuring method specifically comprises the following steps:
(1) testing liquid loaded liquid storage box and seal, open the switch leveling of balance and reset, film object sampling to be measured, be placed in article carrying container or hang on balance hook, seal case closed and seals;
(2) to close between casing and liquid storage box and valve one, three on seal box, open the pipeline valve two connecting vacuum pump, open vacuum pump, (determine according to the saturated vapour pressure under testing liquid normal temperature) when the registration of vacuum meter reaches certain value on vacuum pump, close vacuum pump and the pipeline valve two being connected vacuum pump;
(3) the numerical value m1 recorded after the registration of balance is stablized now is quality before imbibition;
(4) valve one between casing and liquid storage box is opened, testing liquid enters seal case with Sprayable, and be adsorbed in film object to be measured gradually, quality after to record numerical value m2 after the registration of balance is stable be imbibition, in this step, peripheral protective device can play the water that insulation effect also collects seal case and the liquid storage box outside water vapor liquefaction formation caused because vaporizing liquid in liquid storage box absorbs heat rapidly;
(5) after empty pump tail end connects tail gas collecting device, close valve one between casing and liquid storage box, open the pipeline valve two and vacuum pump that connect vacuum pump, the liquid gas in density casing can be discharged, and then open valve three on seal box and be filled with air, complete test operating procedure;
(6) pick up of thin film fluid is calculated according to measurement data m1 and m2.
This device is the device utilizing vaporizing liquid absorption principle to measure object imbibition ability, and first reduce pressure in seal and make vaporizing liquid, gasifying liquid is attracted in film object to be measured, finally by the imbibition ability of mass of object measure of the change object before and after absorption;
Described balance can be suspension type, or pellet type and suspension type dual-purpose;
Described vacuum pump tail end can install tail gas collecting device;
Advantage of the present invention is:
Structure of the present invention is simple, easy to use, it changes traditional object immersion liquid and is placed in conventional gas, but object immersion liquid is placed in the saturated vapour by adsorptive liquid, extend the liquid storage time after film object imbibition, and then measure the quality after its imbibition, this device is used to efficiently solve conventional measurement devices degree of accuracy not high, the problem that operation is loaded down with trivial details, simplifies the operation of measuring process, greatly reduces the error that routine operation is introduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of imbibition capability of film object measurement mechanism, include the seal case 2 that top seal is provided with suspension type balance 1, the loading hook 3 of described balance 1 hangs in seal box, hook 3 hangs with article carrying container 4, fit tightly bottom described seal case 2 on a liquid storage box 6, be communicated with by a valve 1 between casing with liquid storage box 6, seal case 2 middle and lower part is surrounded by protective device 5 together with liquid storage box periphery, described protective device 5 is made up of insulation material, described seal box side is provided with through hole, through hole is connected with pipeline, the pipeline other end is connected with vacuum pump 7, valve 29 is installed in the middle part of pipeline, described seal box side is provided with valve 3 10, atomizing ejecting device is installed near seal case side by described valve three place.
Concrete use step is as follows:
Step a, testing liquid loaded liquid storage box 6 and seals, open the switch leveling of balance 1 and reset, film object sampling to be measured, be placed in article carrying container 4 or hang on balance hook 3, seal case 2 closed and seals;
