Description
Technical field
The present invention relates to a kind of methods for analyzing metal hydride nickel storage battery profiled filament uniformity.
Background technique
Metal hydride nickel accumulator plate on the make, is needed by mixing paste, coated plate, curing and drying, chemical conversion, drying etc.
Process usually adds suitable staple fiber to there is good bond strength in the auxiliary material of mixing paste, and specific amount is 0.09%
~1% etc..How to ensure that profiled filament reaches uniformity in mixing paste, its intensity is being verified after curing and drying whether
It meets the requirements, whether has scaling loss failure after chemical conversion is dry, at present only by the uniformity for visually confirming staple fiber, apparent fiber
It is how many to be lost to determine whether there is, not scientific in this way, no data support.So a kind of method is needed to contain to analyze profiled filament
Amount, makes reasonable judgement.
Summary of the invention
It is an object of the invention to: a kind of method for analyzing metal hydride nickel storage battery profiled filament uniformity is provided,
On the one hand the content of profiled filament is analyzed by this method to determine the uniformity of profiled filament, and on the other hand analysis solidification is dry
The positive positive plate profiled filament content after green plate, chemical conversion drying after dry is lost to determine whether there is, and expires short fibre content
Sufficient technical requirements, the intensity reached guarantee anti-vibration, the resistance to circulation, the performance not fallen off of battery pole plates from source.
The technical solution of the invention is as follows: firstly, being dissolved by dioxysulfate water mixed solution alignment plate, or by sulphur
Acid solution to, green plate, positive plate dissolve；Then, sieving separating goes out staple fiber, dry, obtains staple fiber；Finally, by dividing
Balance weighing apparatus short fibre content is analysed, mass percent of the staple fiber in is calculated.
Wherein, dioxysulfate water mixed solution is by being added 20mL mass concentration 30% in 12% sulfuric acid of 1000mL mass concentration
Hydrogen peroxide composition；Sulfuric acid solution is the sulfuric acid of mass concentration 12%.
Wherein, specific step is as follows for analysis method:
1, green plate, positive plate: taking in bulk, or takes green plate, positive plate, not grind, not be sieved, directly take block,
Weigh 40g (accurately to 0.001g), be put into 500mL beaker, sulfuric acid solution 300mL be added, boils, stirring to without obvious pimple,
So that lead sulfate is in dispersed, slowly it is sieved in the center of 200 meshes, so that staple fiber is deposited in the center of sieve, be washed with water
Wash to the pure white free from admixture of staple fiber, 110 DEG C drying 30 minutes, obtain staple fiber；By assay balance scale short fibre content, calculate
Mass percent of the staple fiber in；
2, positive plate: taking positive plate, not grind, and not be sieved, and directly takes block, weigh 40g (accurately to 0.001g),
It is put into 500mL beaker, dioxysulfate water mixed solution 200mL is added, to without obvious pimple, solution is translucent muddy stirring and dissolving
Turbid shape is slowly sieved in the center of 200 meshes, so that staple fiber is deposited in the center of sieve, it is pure white to be washed with water to staple fiber
Free from admixture, 110 DEG C drying 30 minutes, obtain staple fiber；By assay balance scale short fibre content, matter of the staple fiber in is calculated
Measure percentage.
The invention has the following advantages that it is 1. convenient and efficient, the analysis of multiple samples can be carried out simultaneously, determine a batch mixing paste mistake
The staple fiber uniformity of journey, while can also speculate the uniformity of other materials；2. the chemical reagent type needed is few, treatment process
Simply, free from admixture introduces, and tool is easy to use；3. analyzing, result is accurate and reliable, and staple fiber is obviously clear to.
Specific embodiment
Analysis method of the invention is further illustrated below with reference to specific embodiment, these embodiments are not to be construed as
Limitation to technical solution.
Embodiment 1: the profiled filament quality finished according to the analysis of step in detail below mixing paste:
It takes mixing paste to finish in three times, is sealed by PE bags；Slabbing will be pinched with hand, takes out bulk, it is (accurate to weigh 40g
To 0.001g), it is put into 500mL beaker, the sulfuric acid solution 300mL of mass concentration 12% is added, boils, stirring is to without obvious lump
Carbuncle is slowly sieved in the center of 200 meshes so that lead sulfate is in dispersed, so that staple fiber is deposited in the center of sieve, use water
Washing to the pure white free from admixture of staple fiber, 110 DEG C drying 30 minutes, obtain staple fiber；By assay balance scale short fibre content, calculate
Mass percent of the staple fiber in out.
For staple fiber by when auxiliary material is added, quality 900g, moisture at this time is 18.42%；One pot of (criticizing) group
It is 610 kilograms at quality, then short fibre content dry at this time is 900 × (1-0.1842) ÷, 610 1000 × 100%=of ÷
0.12%, and embodiment 1 measures 0.124%, 0.121%, 0.118% and meets technical requirements.
Embodiment 2: chemical conversion drying is analyzed according to step in detail below and finishes positive plate:
It takes chemical conversion drying to finish positive plate in three times, is sealed by PE bags；Bulk is taken out, weighs 40g (accurately extremely
0.001g), it is put into 500mL beaker, dioxysulfate water mixed solution 200mL is added, to without obvious pimple, solution is in stirring and dissolving
Translucent muddiness shape, is slowly sieved in the center of 200 meshes, so that staple fiber is deposited in the center of sieve, be washed with water to short
The pure white free from admixture of fiber, 110 DEG C drying 30 minutes, obtain staple fiber；By assay balance scale short fibre content, staple fiber is calculated
Mass percent in.
Positive plate is to obtain 92g at this point, to return to meter before the non-coated plate of 100g after curing and drying, chemical conversion are dry
Staple fiber additive amount is calculated, then 0.92 × 0.128%=0.118%, differs only by 0.002% with technical requirements；B, the return of C calculates
Respectively 0.113%, 0.117%, absolute error meet technical requirements less than 0.01%.
