成型绝缘件添加棉浆的工艺研究

Insulation-shaping Components Add Cotton Pulp Technology Was Studied

由于棉浆的独特性以及能提高输电电缆和变压器绝缘材料的击穿强度、老化寿命、运行可靠性及降低其介质损耗特点,所以其纤维被广泛地应用在绝缘纸板和成型绝缘件中。众所周知,纤维素的来源不同,纤维素的结晶度、分子链的长度、半纤维素和木素含量等也就不同,对产品的绝缘性能也产生了不同的影响。为了达到成型绝缘件的高质量、低成本,并各具特点的要求,选取了应用成熟的瑞典阿斯帕高寒带生长的木浆纤维和山东吉藁生产的高纯度精制棉浆进行了研究并得出结论。

the dielectric loss, so the cotton fiber is widely used in insulation board and insulation forming parts. As is known to all, the source of the cellulose, the crystallinity of cellulose, the length of the chain, hemicellulose, and lignin content are different, such as the insulation performance of products also have different impact, in order to achieve insulation forming parts of high quality and low cost, and each has its characteristics, has chosen the company application mature Swedish spa paramos growth of wood pulp fiber and shandong ji chaff production of high-purity refined cotton pulp： the study and draw conclusions as follows.
