Equipment for the assembly of the main mold material there is bad, do not wear-resistant, dust pollution is serious and so on. Mechanical plant should be strengthened with metal materials research department collaboration, select the applicable cathode ring mold materials and heat treatment method.

To promote mercury-free alkaline manganese battery, the process, it is necessary to down-to-earth manner, some base building. Mercury-free alkaline manganese batteries need to be dedicated to further improve the quality of EMD, in particular heavy metal impurities are no longer content to be reduced, but also improve the battery at high voltage potential and discharge capacity of the whole point of martial arts.
For alkaline manganese batteries graphite powder, a lot are processed by the squamous form of graphite, and graphite in squamous Fe, Cu and other elements with a high level. Without effective control measures and testing means, such graphite production of mercury-free batteries, can lead to major quality accidents.
China has not completely mercury-free zinc clearance from the selection of high-quality zinc starting material, but also must look at appropriate processing methods. Al with Ca in place of the In-Bi 1 Ca zinc alloy is more conducive to reduce the mercury-free alkaline manganese battery storage period of chronic short-circuit. Analysis selection depth of discharge gas on the low zinc dependent solution are mercury-free battery storage and resistance to leakage of important performance measures.
Alkaline manganese batteries divide need to further improve performance, improve density and uniformity, increase block. Korea provided technology divide winding spiral winding method, to meet the requirements for mercury-free, to recommend appropriate winding adjust the angle so that the effective increase in low-rise. Reduce the membrane thickness of paper to increase the winding layers, which is the international alkaline manganese battery industry is a tendency.
CMC, such as traditional zinc ointment Thickening the use of mercury-free zinc powder stability variation, can not meet the requirements of mercury-free battery. To enhance the mercury-free alkaline manganese batteries of anti-vibration performance and storage performance, the proposed selection of PA and PA 1 Na high viscosity, good stability of zinc paste thickener, and select the appropriate ratio, the performance of battery will be more the desired results. Alkaline manganese battery of standardized parts alkaline manganese batteries are mercury-free implementation of the basic conditions. Alkaline manganese battery set up some spare parts base, strengthen the quality control of parts of the alkaline manganese battery improve the quality of implementation of mercury-free alkaline manganese batteries is very important.
