摘要: 为了从制备光纤预制棒产生的废料中提取得到白炭黑,采用烘干、研磨、煅烧、酸处理、水洗等手段对废料进行无害化处理,除去杂质部分,使超细二氧化硅颗粒再生出来。重点探究了最佳的煅烧条件,通过对不同煅烧条件下产品的失重分析以及杂质(Fe元素)含量、产品粒径分布等分析,得出了最佳的煅烧温度为500 ℃,煅烧时间大约为1 h。所得产品的质量技术参数基本达到或接近国家标准。

关键词: 光棒废料, 煅烧, 白炭黑

Abstract: In order to recycle white carbon black from the waste generated from the preparation of optical fiber preforms,im- purities in the waste were removed by drying,grinding,calcination,acid treatment,washing,and other harmless treatments to regenerate the ultrafine silicon dioxide particles.The optimum calcination conditions were explored especially.Through the analysis of weight loss,the content of the impurity element(Fe),the product particle size distribution under the different cal- cination conditions,a conclusion was drawn that the best calcination temperature was 500 ℃ and the best calcination time was about 1 h.The quality parameters of the product reached or were close to the national standards.

Key words: optical fiber preform waste, calcination, white carbon black
