Raw material proportioning and mixing of solar EVA adhesive film
The raw material of solar energy EVA adhesive film generally adopts EVA particles for photovoltaic from foreign original manufacturers such as DuPont, Mitsui and Bridgestone, which can be directly used for mixing without granulation. However, if EVA particles from domestic manufacturers, especially some small manufacturers, are used as raw materials, because their sources are often very complex, even including the leftover materials from photovoltaic module factories, this material needs to be reprocessed, crushed and granulated, and the corresponding process parameters and mixing proportion must be controlled. Even if this is done, the quality of the final finished EVA is still difficult to control. If it is continued to be used in the photovoltaic industry, especially in the manufacturing of large components, it will leave many hidden dangers.
In the process of mixing raw materials of EVA film, the proportion of some additives is very low (such as less than 0.1%), so how to make these low proportion additives mix evenly is a very important process problem. The method of multiple mixing can be adopted to mix the small proportion of additives with a small amount of other materials, then with more other materials, and finally with all other materials. After such mixing for many times, the problem of uniformity of low proportion additives can be solved.
In order to ensure the accuracy of proportioning and the uniformity of mixing, full-automatic vector weighing and mixing device can be selected. In order to prevent the overheating of EVA raw materials in mixing, low-temperature and low-speed mixer should be selected.
