摘要
玻纤原丝筒的烘干过程是加热→气化→迁移→气化过程.影响纤维烘干速度的因素有烘干温度,加热介质的流动速度,烘干空间的相对湿度、原丝简的厚度及其在烘房内的排列位置.纤维烘干的均匀度主要由烘房的结构决定.电、蒸汽、天然气、煤汽均可以作为原丝烘干的能源,各有利弊.烘干温度及烘干工艺应根据纤维用途不同而不同.此外,原丝筒烘干用小车的设计对烘干成品率有很大的影响.
The drying process of glass fibre strand cakes could be regarded as a course of heating→vaporization→migration→vaporization. The factors governing the drying rate are drying temperature, flow velocity of heating medium, relative humidity in the drying oven, and thickness and arrangement of cakes in oven, while the drying homogencity primarily depands on the structure of the drying oven. Electricity, steam, nature gas and producer gas could all be used as the energy sources of drying, each has its own merits. The end applications of glass fibre require different drying process and temperatures.
