Environment-friendly adhesive/New energy vehicle adhesive/battery adhesive mixing equipment
According to the adhesives mentioned by professional teachers in the adhesives forum held in March 2024, they are widely used in the current automotive industry, especially with the continuous development of the new energy industry, the use of adhesives is becoming more and more demanding.
Conventional new energy power battery adhesives mainly use polyurethane structural adhesives, potting adhesives, etc. In the actual mixing process, uneven mixing is often encountered, as a result, less than ideal adhesive effects will occur during application;
The technical staff of Shanghai ELE Mechanical & Electrical Equipment Co., Ltd. infer the main reasons for the non-uniformity according to the appearance of the product.
1. Selection and design of mixing equipment:
Did not select the appropriate mixing equipment or in the process of designing mixing equipment did not take into account the requirements of the material viscosity to the mixer, such as: when the viscosity is higher than 20000cps or in the mixing process there is a short time higher than 20000cps of the material, only the use of conventional high-speed dispersing machine, it is difficult to mix the material evenly or it is easy to produce dead corners in the mixing;
At this time, according to the level of viscosity, the designer of Shanghai ELE company recommend that we should choose a compound high-speed dispersion mixer or a double-planet mixer, which not only overcomes the influence of viscosity but also makes the material mix more evenly.
The material flow between the bottom of the mixing barrel, the dispersion tray and the discharge port is not considered in the design process of the conventional composite mixing frame, which results in a dead Angle.
In the design process, ELE team used different anti-dead Angle and anti-blocking material design according to the situation of the material.
2. The installation, quantity and coordination of other mixing forms of dispersion plates in the mixing process:
The driving amount of the driving surface of the dispersion disc in different positions and the three-dimensional space arrangement of the dispersion disc will affect the mixing effect of the adhesive. In the actual mixing process, the number of different dispersion discs or the dispersion device with different installation positions should be selected, and then combined with the barrel body of the adhesive will not only improve the mixing effect but also improve the efficiency of mixing.
According to the actual situation of the material, the designer of ELE team will recommend single, double or multi-disk structure, and will also choose single axis, double axis or multi-axis coordination according to the viscosity of the material, and the form of different mixing forms at the same time to improve the effect.
3. The proportion of the diameter of the dispersion plate in the mixing equipment and the height of the bottom of the barrel:
For materials with low viscosity, the speed and load of the mixing and dispersing machine are affected. In the actual mixing and dispersing process, the ratio of the diameter of the dispersing disc to the diameter of the barrel, the height of the dispersing disc from the bottom of the barrel and the height of the dispersing disc. The diameter relationship will affect the mixing effect.
For example, the mixing effect of the container is not good;The container is too small to stir, and the bottom material cannot be mixed evenly.The dispersion tray is high from the bottom of the barrel body, and the bottom material cannot be turned over;The dispersion plate is close to the bottom, and the material rotates in place to form a large group of uneven.
The designers of ELE team will choose the appropriate diameter ratio and bottom height according to the material situation, so as to avoid the occurrence of the above situation, and can be adjusted immediately according to the actual use of the situation, so as to ensure the mixing effect of the material.
