Abstract
The present invention discloses a mercury-free zinc-manganese cell with a paper board, which uses non-poisonous harmless bismuth trichloride instead of virulent mercury chloride as a corrosion inhibitor for a zinc electrode of the cell to make the electric property of the cell reach a national standard. The present invention adds the bismuth trichloride into the coating pulp of pulp-layer paper which is used as a cell diaphragm arranged between a cell anode and a zinc cathode. The present invention has the advantages of improving workers' production environment, making production workers free from mercury poison, simultaneously avoiding environmental pollution caused by optional abandonment of waste cells containing mercury and eliminating public disasters of mercury.
Description
The present invention relates to a kind of improved zinc-manganese cell with paperboard partition.
The corrosion inhibiter that existing zinc-manganese cell with paperboard partition adopted all is at the pasting adding 0.05%-0.5% of battery electricity liquid or positive mix or pulp layered paper mercury chloride (HgCl
2) solution.As the corrosion inhibiter of zinc electrode, this is one of effective ways that reduce at present the zinc self discharge to mercury chloride in zinc-manganese cell with paperboard partition.Add a small amount of mercury chloride and form zinc amalgam, make zinc surface more even, increase the reactive activity area, reduce electrochemical polarization, can also improve the overpotential that hydrogen is separated out simultaneously, reduce the self-dissolving speed of zinc, thereby improve the electric property and the shelf characteric of battery.But mercury is the material that severe toxicity is arranged, and normal temperature can become mercury vapour, and direct labor's health is had very big harm; In addition, arbitrarily abandon with the refuse battery of crossing and to pollute the environment, cause the mercury public hazards.At present, many in the world countries have proposed limit production and have used the proposal that contains mercury cell.For above-mentioned reasons, what material to replace mercury chloride to become a great research topic of battery industry as the corrosion inhibiter of Battery Zinc electrode with; But up to the present use the corrosion inhibiter of single additive as zinc electrode, electric property does not also reach the level of mercury chloride as the zinc electrode corrosion inhibiter of using.
The purpose of this invention is to provide a kind of zinc-manganese cell with paperboard partition that does not have mercury, it replaces the mercury chloride of severe toxicity to be used as the corrosion inhibiter of Battery Zinc electrode with nontoxic, harmless bismuth trichloride, and its electric property is met international standards.
It is the polyacrylamide (PAM) of 0.5%-1.5%, the polyvinyl alcohol (PVA) of 3%-6%, the zinc chloride (ZnCl of 2%-3% that the present invention adopts weight ratio
2), chemical industry modified starch (EcS), 0.4%-0.5% octyl phenol APEO (Tx-10) and an amount of water (H of 40%-45%
2O) stirring is mixed, and adding weight ratio then is the bismuth trichloride (BiCl of 0.25%-0.45%
3), viscosity, the filtration by regulating slurries and to make the weight ratio of water be surplus then becomes the painting slurry of no mercury, and this pasting is coated on cable paper or the basic paper and dries through coating machine, just becomes non-mercury pulp layered paper.These pulp layered papers are placed between anode and the zinc negative pole as battery diaphragm, and these pulp layered papers have been formed the zinc-manganese cell with paperboard partition of bismuth trichloride for mercury with anodal, negative pole.
The present invention is through anatomic observation zinc metal sheet corrosion situation, show that corrosion inhibiter bismuth trichloride and mercury chloride are absolutely different to the inhibition mechanism of zinc electrode, mercury chloride is in zinc surface generation displacement reaction, further spread then to nexine, generate zinc amalgam, thereby improve the surface appearance of zinc, improve the hydrogen overvoltage of zinc, zinc metal sheet is played corrosion inhibition; And bismuth trichloride is to form dense overcoat at zinc surface, form the good metal film, this tunic being property after being dissolved in diluted acid is a metal, through the X diffraction, determine that this tunic is that metal constitutes, therefore, using bismuth trichloride is nontoxic as the corrosion inhibiter of zinc electrode, it is harmless, and can not cause environmental pollution.Simultaneously, utilize the battery of bismuth trichloride,, thereby play corrosion inhibition because the zinc electrode surface forms layer protecting film as corrosion inhibiter.
The present invention replaces the mercury chloride of severe toxicity to be used as the corrosion inhibiter of Battery Zinc electrode with nontoxic, harmless bismuth trichloride, and its electric property is met international standards.It has improved the environment that the workman produces, and makes the direct labor avoid mercury and poisons, and has avoided mercury-containing battery arbitrarily to abandon and the environmental pollution that causes simultaneously, has eliminated the mercury public hazards
Elaborate below in conjunction with the performance of accompanying drawing to the embodiment of the invention, accompanying drawing is a process diagram of the present invention.
Under the same process condition, the zinc-manganese cell with paperboard partition that zinc-manganese cell with paperboard partition that the bismuth trichloride pulp layered paper that adopts the present invention to prepare different content is made and mercury chloride pulp layered paper are made, according to standard GB 7112-86 and IEC86-2 standard discharge contrast, electrical property and storage biannual test result are as follows:
A group: 0.3%BiCl
3
B group: 0.4%BiCl
3
C group: 0.45%BiCl
3
D group: 0.2%HgCl
