Hollow glass fiber production method

Abstract

The invention relates to a process method for hollow glass fiber, which comprises: arranging special discharge spouts on Pt discharge plate for glass to pass, putting one Pt air-blowing pipe with Pt / Rh=90 / 10 on midst of every spout with lower end to form column gap with spout and top end connected to compress-air device; blowing air as proper quantity by pipe into spout, driving fusing glass to cross the gap and generate hollow when translating into fiber. Wherein, the air in glass fiber can lead to reduction of dielectric coefficient.

Description

technical field

[0001] The invention relates to a method for manufacturing glass fibers, in particular to a method for manufacturing hollow glass fibers. Background technique

[0002] The dielectric coefficient of air is 1, and the level of dielectric coefficient directly affects the quality of products in various fields of use. Low dielectric constant glass fibers are used in many fields. Low dielectric constant circuit substrates made of low dielectric constant glass fibers can be used for high-density wiring, reduce signal loss, and increase signal propagation speed. For example, use low dielectric constant The high-density ultra-thin printed circuit board made of glass fiber can increase the computing speed of the computer; the radome made of glass fiber with low dielectric coefficient can reduce electromagnetic wave deformation and energy loss; the invisible glass fiber made of low dielectric coefficient Aircraft materials improve the transmittance of electromagnetic w...
