Three factors affecting the life of alkaline battery.

2021-04-28 08:56:14 | 不老長寿

How to improve the lifespan of alkaline battery has always been the focus of research in the battery industry. Among them, the composition, type, porosity, plate size, grid material and structure of the active material are internal factors that affect the life of alkaline battery, while the depth of discharge, overcharge level and temperature are external factors.

1. The influence of temperature. The lifespan of alkaline battery increases with increasing temperature, because the capacity increases with increasing temperature. If the discharge capacity does not change, then when the temperature rises, the depth of discharge is reduced to extend the lifespan. Between 10-35 Celsius, the temperature rises by one Celsius, an increase of 6 cycles. Between 35-45 Celsius, each Celsius of temperature rise can extend the lifespan by more than 25 cycles. When the temperature is higher than 50 Celsius, the lifespan is shortened due to the loss of cathode vulcanization capacity.

2. Depth of discharge. The depth of discharge means that the discharge starts to stop when it reaches a certain level during use, and 100% depth refers to the discharge of all capacity. The lifespan of alkaline battery is greatly affected by the depth of discharge. Because the anode active material lead dioxide itself is not firmly bonded to each other, lead sulfate is generated during discharge, and returns to lead dioxide during charging. The molar volume of lead sulfate is larger than that of lead oxide, so the volume of the active material expands during discharge. Therefore, the deeper the depth of discharge, the shorter the cycle life.

3. The degree of overcharge. A large amount of gas is released during overcharging. At this time, the active material of the positive plate is impacted by the gas, and this impact will promote the active material to fall off. In addition, the positive grid alloy is also subject to severe anodic oxidation and corrosion, so the service life of alkaline battery will be shortened when overcharged.

Only by strictly and comprehensively controlling the internal and external factors that affect alkaline battery can alkaline battery with longer lifespan be produced.

 

Basic attributes of packaging machinery, packaging machine manufacturers

Basic attributes of packaging machinery:
Different companies have different preferences for different types of small bag flexible packaging machinery, and different products have different suitable performances for different types of small bag flexible packaging machinery. Although the packaging process of different types of packaging equipment includes the main steps of packaging film movement, bag forming, filling materials, sealing, and cutting.

Taking the most common three-side sealing and four-side sealing packaging machinery as an example, the width (relative to the vertical packaging machine) or length (relative to the horizontal Packaging machine).

By choosing the sealing roller or plywood of different sealing pattern molds, diversified sealing patterns can be realized, such as checkerboard pattern, horizontal line pattern, bottle-like sealing, sealing with embossing and so on.

The cutting method can also be selected from a variety of cutting methods such as flat cutting, sawtooth, and dot-dash line.

Basic quality assurance of packaged products:
The change of the sealing pattern provides customers with diversified options, and the firmness of the sealing is one of the most basic indicators to measure mechanical performance. Standard packaging film, usually the sealing strength of the packaging of liquid products should be able to withstand a static pressure of 80 kg without leakage, and the sealing strength of the packaging of powder products should be able to withstand a negative pressure of 450 mmHg for 20 minutes without leakage Detection.

The emergence of more and more shopping supermarkets requires the packaging of goods not only to meet the safety of the packaging products’ hygiene, transportation, and storage. This is a basic requirement. At the same time, it is a basic requirement for packaging products, especially outer packaging products, to pass display shelves. Ease of display, brand emphasis, etc. all put forward higher requirements for commercial aesthetics. Therefore, the different manufacturing technologies and design principles of various packaging machines provide users with diversified choices.

If the packaging type of the pouch packaging is classified according to the appearance, it can be roughly divided into the following three main categories: three-side sealing, four-side sealing, and back sealing (or called pillow bag). Of course, on this basis, there are very rich varieties of deformation.

What should I do if the powder is clamped during packaging by the Powder Packing Machine?

2021-04-25 11:26:39 | 日記

The Powder Packing Machine, especially the vertical Powder Packing Machine, may cause the bag opening to be not tightly closed or affect the appearance during the packaging. As for how to solve the powder clamping, we must first find out the cause of the powder clamping. Reasons in order to solve them in a targeted manner.

Based on on-site experience, we summarize the causes and solutions of several failures causing powder clamping:
1. The timing of horizontal sealing is too high.
Solution: Adjust the horizontal sealing time
2. The blanking device is not tightly closed, and there is material leakage.
Solution: Mainly spiral feeding method, adding leak-proof device
3. The bag maker electrostatically adsorbs materials.
Solution: Find a way to eliminate the static electricity of the packaging material, or add an ion wind device.

The main measures to prevent leakage of alkaline battery.

2021-04-24 17:14:19 | 不老長寿

The leakage of alkaline battery has a very important relationship with the structure of the battery. Because the cathode active material is zinc powder, it greatly increases the real surface area of the cathode and increases the battery capacity. But at the same time, it is prone to corrosion. There is a lot of gas generated inside the battery. When the internal pressure is too high, the strong pressure may deform the parts at the seal and cause the battery to leak.

In order to prevent the leakage of alkaline battery, alkaline battery manufacturers usually take the following measures in the production:

1. Apply sealing glue. Since the contact surfaces of the seals are not all really flat and there are many capillary channels, sealing glue must be applied between the steel cylinder and the sealing ring and the center of the sealing ring to block the capillary channels.

2. Improve the sealing structure and sealing process. Since the outer diameter of the upper part of the sealing ring is tightly fitted with the inner diameter of the flaring part of the steel cylinder, the outer diameter of the lower part of the sealing ring is a loose fit with the inner diameter of the steel cylinder. Therefore, only by axially and radially compressing the upper part of the sealing ring can the sealing purpose be achieved.

3. Improve the sealing ring. The material and structure of the sealing ring are also the main measures to improve the sealing effect. After comparing several common sealing processes and the principle of the sealing machine, it is found that the key to the sealing process is the deformation of the steel shell and the elastic compression of the sealing ring. The compression effect is achieved in the transverse direction, and the purpose of sealing can be achieved.

Prevent the leakage of alkaline battery and do a good job of quality control, so that alkaline battery can always make breakthroughs and walk in the forefront of the battery industry.
