Abstract

The invention belongs to the technical field of quartz glass processing in the optical fiber communication industry, and particularly relates to a nano aluminum oxide coating process for preventing high-temperature deformation and adhesion of quartz glass. According to the process, high-purity nano aluminum oxide, nano zirconium oxide and nano silicon carbide are selected and mixed in proportion to form powder; and through a high-temperature sintering process, the powder is uniformly sintered on the surface of a quartz glass sphere to form a coating, attachments can be effectively combined with quartz glass to reach a nanoscale level, the strength and toughness of the coating are greatly improved, the temperature resistance of the surface layer of the quartz glass and the strength and toughness of the glass are improved, the thickness of the coating is controlled to be 18-20 micrometers, then flame baking is conducted, the binding force of the coating reaches 30-50 Mpa, and the abrasion resistance of the attached surface is improved; and finally, the quartz glass is subjected to destressing treatment, so that the use temperature of the quartz rod handle is effectively increased, the replacement frequency of the quartz hanging rod is effectively reduced, the production risk is reduced, and the production capacity efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of quartz glass processing in the optical fiber communication industry, and in particular relates to a nano-alumina coating process for preventing high-temperature deformation and adhesion of quartz glass. Background technique [0002] In the optical fiber communication industry, optical fiber cable is the basic material, and the production of optical fiber preform is the core technology of optical fiber communication. Optical fiber preform manufacturing is divided into core rod manufacturing and outer cladding manufacturing, that is, the core rod (including the core layer and optical cladding) is manufactured first, and then the cladding is deposited on the outside of the core rod to obtain an optical fiber preform rod. The manufacturing methods of optical fiber preform core rods mainly include axial vapor deposition (VAD), modified chemical vapor deposition (MCVD), plasma chemical vapor deposition (PCVD) a...
