NOZZLES FOR MANUFACTURING FIRST COATING OF OPTICAL FIBRES, AND METHOD OF MANUFACTURING THE NOZZLE |
摘要 |
<p>A nozzle used in the coating of optical fibers with a protective resin layer comprises an aluminum body split into two symmetrical halves with cavities which upon assembly form a frustoconical funnel terminating at its narrower lower end in a coaxially converging outlet port. The cavities are machined in solid aluminum blocks whereupon each block is anodized in sulfuric acid to form thereon an abrasion-resistant oxide layer with few, small pores which may be sealed by an aftertreatment in hot de-ionized water.</p> |
