Embodiment example

[0008] A high silica fiber glass binary component formulation: SiO 2 : 76.0%; Na 2 O: 21.0%; Al 2 o 3 : 3%.

[0009] The above components are prepared according to the following process to prepare binary component high silica fiber glass. The specific process is as follows:

[0010] Raw material preparation: taking 100g of glass as an example, 65.8g of quartz sand, 33.0g of soda ash, 15.3g of albite feldspar, and 0.38g of sodium sulfate.

[0011] After the above raw materials are mixed, they are melted and drawn in a platinum crucible. After the wire drawing is finished, the conventional winding and weaving processes are adopted. I won't repeat it here.

[0012] The relevant performance data of the high silica glass fiber (such as high silica mesh BWT7*7-90) made from the above components and the high silica glass fiber made from the three-component component are as follows:

Abstract

The invention relates to a high-temperature-resistant high-silica fiber glass. The compound comprises the following components by weight percent: 74.0-77.0% of SiO2, 20-23% of Na2O and 1-3.5% of Al2O3. The high-silica fiber glass has the advantages that the high-silica fiber glass which is produced through a binary component formula has the obvious characteristics of low cost, low thermal shrinkage, high strength, excellent temperature resistance, soft texture and the like as well as low fiber drawing operation temperature, large difference of fiber forming temperature and glass crystallization upper limit temperature, high fiber dripping and filtering velocity, high fiber strength, good mechanical performance and abrasion resistance.

Description

technical field [0001] The invention relates to a high temperature resistant high-silica fiber glass binary component formula and its production process, especially the fiber glass component is two components and does not contain relatively high-cost B 2 o 3 . Background technique [0002] The original glass component of high silica fiber produced in my country is SiO 2 —B 2 o 3 —Na 2 O ternary system is the main method. During the production process, due to the large volatilization of boric acid and the large loss, it causes environmental pollution. The strength of the produced glass fiber is low, and the material loss is large during the leaching process. Hydrochloric acid must be used as the leaching agent, and the leaching speed is slow. Moreover, during the acid treatment process of the ternary component glass fiber, boric acid is still leached out by acid, so the manufacturing cost is relatively high, which cannot meet the needs of some special fields. SiO 2 ...
