The reform of partially Pt-substituted bushing furnace is an important measure to improve the quality of glass melt and the fiber drawing process.
对于不具备制球条件的玻纤企业，代铂炉型的改进是改善玻璃液质量，提高拉丝作业水平的重要措施。
Moreover, the NH4HF2 content in the batch, the temperature distribution in the fiber-drawing furnace, and fiber drawing technology also have influence on the scattering loss of the fiber.
配合料中引入适量NH_4HF_2，选用温度结构合理的拉丝炉及拉丝工艺也有助于降低光纤的损耗。
