The high silica fiber can keep good strength and elasticity for a long time at 1000 ℃, and is an effective heat barrier for ultrahigh-temperature heat flow and jet flame and a reliable protection device for personnel facilities; the high-temperature resistant alloy has low heat conductivity coefficient, has good resistance to high-temperature impact, is inert to most chemicals, has good corrosion resistance to compounds at high temperature, corrosive minerals and weakly alkaline molten alloy, and can normally and continuously work under the conditions of high heat and strong radiation.
In the production, the high silica fiber continuous yarn is formed by drawing, untwisting and twisting high silica glass balls to form the high silica fiber continuous yarn (base yarn) with the silica content of 66-68%, then hydrochloric acid leaching is carried out, and phase separation of the structure is utilized to lead B to be separated from B 2 0 3 And Na 2 Leaching out O component and transferring into solution to make Si0 2 Obtaining a microporous silica framework with the enrichment of more than 96 percent to obtain high silica fiber yarn with the silica content of more than 96 percent, performing high-temperature sintering and shaping at the temperature of 600-800 ℃ to close micropores generated by chemical reaction of the yarn in the acid leaching process to prepare high-performance high silica fiber continuous yarn, and finally performing integral soaking, coating and drying to obtain the high silica fiber continuous yarn; the high silica fiber continuous yarn can be used for a long time at 900 ℃, and is mainly used for the aspects of military industry, aerospace and the like.

In order to use the high silica continuous yarn for weaving, some manufacturers coat the high silica continuous yarn with various coating materials to improve the strength of the yarn, and most of the coating materials are polytetrafluoroethylene emulsion. If the leached impurities in the acid leaching process of the high-silica continuous yarn are not cleaned, the sintered yarn has basically no strength at the positions which are not cleaned, the yarn still has no strength after being coated, and breakpoints exist in the later use process of the yarn, so that the yarn is broken.

High silica matrix glass spheres (with the component content of SiO) 2 66-68% of Na 2 O is 7-8%, B 2 O 3 22-23% of Al 2 O 3 1-5%) is added into a crucible, melted at 1350 ℃ and drawn into silica precursor with the linear density of 32tex, the silica precursor with the linear density of 32tex is untwisted and twisted by a twisting machine to form silica continuous yarn with the linear density of 288tex, the silica continuous yarn with the linear density of 288tex is leached by hydrochloric acid, and Na in the yarn components 2 O and B 2 O 3 Separating phase in hydrochloric acid, leaching all the solution into hydrochloric acid solution, washing with water, and washing hydrochloric acid and other impurities in the yarn to obtain SiO 2 High silica fiber continuous yarn with content of more than 96% and linear density of 240 tex; putting the 240tex continuous yarn into a 600-800 ℃ high-temperature sintering furnace for heat sintering and shaping treatment to prepare 220tex sintered continuous yarn (at the moment, the yarn strength test is 0.05-0.08N/tex on average); and (3) soaking and coating the 220tex sintered continuous yarn in the coating liquid for 60min, taking out, and then drying in a drying room at 80 ℃ to obtain the high silica glass fiber continuous yarn with high strength (at the moment, the strength test of the yarn is more than 0.45N/tex).
The high silica glass fiber continuous yarn coated with the coating material of the present invention in examples 1 to 3 and the high silica glass fiber yarn not coated with the coating material of the present invention were respectively subjected to performance tests as comparative examples, and the test results are shown in table 1.
Table 1 comparative table of the performance tests of continuous yarns of high-silica glass fibres coated with a coating according to the invention and uncoated
The case of particularly low strength, which occurs in the test strength, is treated as an abnormal case, the main reason for which is that the coating solution cannot effectively repair and increase the strength of weak spots, which are caused by the yarn before coating.
As can be seen from Table 1, after the high silica glass fiber continuous yarn is coated with the coating material, the strength of the high silica glass continuous yarn is more than 6 times of that of the yarn before coating, the yarn strength is actually measured to be 0.54N/tex, the yarn strength is improved, the yarn surface is smooth, and the technical problem that the high silica glass continuous yarn cannot be woven or knitted is solved.
The above examples merely illustrate specific embodiments of the present disclosure, but embodiments of the present disclosure are not limited by the above. Any changes, modifications, substitutions, combinations, and simplifications which do not materially depart from the spirit and principles of the inventive concepts disclosed herein are intended to be equivalent permutations and to be included within the scope of the invention as defined by the following claims.
