Description
Technical field
The present invention relates to silicon energy batteries, and in particular to a kind of analysis side of silicon energy battery pole plates lead plaster middle short fiber content
Method.
Background technique
Silicon energy battery pole plates on the make, are needed by processes such as mixing paste, coated plate, curing and drying, chemical conversion, dryings, in order to
Lead plaster has good bond strength, and suitable staple fiber is usually added in the auxiliary material of lead plaster mixing paste, and specific amount is 0.09%
~1% etc..How to ensure that lead plaster middle short fiber reaches uniformity in mixing paste, its intensity is being verified after curing and drying
Whether meet the requirements, whether has scaling loss failure after chemical conversion is dry, at present only by the uniformity for visually confirming staple fiber, apparently
How much fiber loses to determine whether there is, not scientific in this way, no data support.So needing a kind of method short in lead plaster to analyze
Fiber content makes reasonable judgement.
Summary of the invention
It is an object of the invention to: a kind of analysis method of silicon energy battery pole plates lead plaster middle short fiber content is provided, is passed through
On the one hand this method analyzes the content of lead plaster middle short fiber to determine the uniformity of lead plaster middle short fiber, on the other hand analyze solid
The positive positive plate lead paste middle short fiber content after green plate, chemical conversion drying after changing drying is lost to determine whether there is, and makes short fibre
Dimension hplc meets technical requirements, reaches the intensity of lead plaster, from source guarantee battery pole plates anti-vibration, it is resistance to circulation, lead plaster not
The performance to fall off.
The technical solution of the invention is as follows: firstly, dissolved by dioxysulfate water mixed solution alignment plate lead plaster, or
Lead plaster, green plate, positive plate lead plaster are dissolved by sulfuric acid solution；Then, sieving separating goes out staple fiber, dry, obtains short fibre
Dimension；Finally, calculating mass percent of the staple fiber in lead plaster by assay balance scale short fibre content.
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, lead plaster, green plate, positive plate lead plaster: taking lead plaster in bulk, or takes green plate, positive plate lead plaster, not grind, should not mistake
Sieve directly takes block, weighs 40g and (accurately to 0.001g), is put into 500mL beaker, sulfuric acid solution 300mL is added, boils, stirs
It mixes to without obvious pimple, so that lead sulfate is in dispersed, is slowly sieved in the center of 200 meshes, is deposited in staple fiber
The center of sieve, is washed with water to the pure white free from admixture of staple fiber, 110 DEG C drying 30 minutes, obtain staple fiber；It is short by assay balance scale
Fiber content calculates mass percent of the staple fiber in lead plaster；
2, positive plate lead plaster: taking the lead plaster of positive plate, not grind, not be sieved, and directly takes block, 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 lead plaster.
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 lead plaster middle short fiber quality finished according to the analysis of step in detail below mixing paste:
The lead plaster for taking mixing paste to finish in three times is sealed by PE bags；Lead plaster is pinched into slabbing with hand, takes out blocky lead plaster,
40g is weighed (accurately to 0.001g), to be put into 500mL beaker, the sulfuric acid solution 300mL of mass concentration 12% is added, boils, stir
To without obvious pimple, so that lead sulfate is in dispersed, slowly it is sieved in the center of 200 meshes, staple fiber is made to be deposited in sieve
Center, be washed with water to the pure white free from admixture of staple fiber, 110 DEG C drying 30 minutes, obtain staple fiber；By the short fibre of assay balance scale
Dimension hplc calculates mass percent of the staple fiber in lead plaster.
For staple fiber by when auxiliary material is added, quality 900g, moisture at this time is 18.42%；One pot of (criticizing) lead
It is 610 kilograms that cream, which forms 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: the dry lead plaster for finishing positive plate of chemical conversion is analyzed according to step in detail below:
The dry lead plaster for finishing positive plate of chemical conversion is taken in three times, is sealed by PE bags；Blocky lead plaster is taken out, it is (accurate to weigh 40g
To 0.001g), it is put into 500mL beaker, dioxysulfate water mixed solution 200mL is added, stirring and dissolving is to without obvious pimple, solution
Be translucent muddy 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
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, short fibre is calculated
Tie up the mass percent in lead plaster.
Positive plate lead plaster is after curing and drying, chemical conversion are dry, and the lead plaster before the non-coated plate of 100g obtains 92g lead at this time
Cream will return and calculate staple fiber additive amount, then 0.92 × 0.128%=0.118%, differs only by 0.002% with technical requirements；B,
It is respectively 0.113%, 0.117% that the return of C, which calculates, and absolute error meets technical requirements less than 0.01%.
