Title: 锂电池基膜生产流程
English: The production of battery separator films involves a series of meticulous processes.Initially, the raw materials, mainly consisting of polyethylene or polypropylene, are selected and prepared.Then, a casting process is employed to form a thin film from the molten material.
中文: 锂电池基膜生产涉及一系列精细的过程。

首先，主要原料为聚乙烯或聚丙烯的原料被选择并准备。

然后，采用铸膜工艺，将熔融材料形成薄膜。

English: The cast film is then dried to remove any remaining moisture.Following drying, the film is stretched in both machine and transverse directions to enhance its strength and durability.After stretching, the film is heat-set to ensure dimensional stability.
中文: 铸膜后，需要干燥以去除剩余的水分。

干燥后，薄膜在机器和横向方向上被拉伸，以提高其强度和耐用性。

拉伸后，薄膜进行热定型，以确保尺寸稳定性。

English: Next, the film undergoes a series of quality checks to ensure it meets the required specifications.This includes testing for physical properties such as thickness, tensile strength, and elongation, as well as for chemical resistance and electrical insulation.
中文: 接下来，薄膜需要进行一系列的质量检查，以确保其符合所需规格。

这包括测试物理性质，如厚度、拉伸强度和伸长率，以及化学耐性和电气绝缘性。

English: Finally, the film is wound onto rolls for further processing or direct use in battery production.The entire production process is carefully controlled to ensure the final product has the desired properties and performance.
中文: 最后，薄膜被卷绕到卷筒上，用于进一步加工或直接用于电池生产。
