Problems solved by technology

The alkali-resistant glass fiber produced by this kind of glass ball is used to produce glass fiber reinforced cement products with a service life of only about 50 years. Although it can meet the durability requirements of conventional buildings and civil engineering, due to its Z r o 2 content is relatively low, while T i o 2 The content is relatively high, so the glass fiber used to produce neither meets the technical standards of high zirconium alkali-resistant glass fiber, nor can it meet the needs of construction and civil engineering with high alkali resistance and long service life; in addition, the above Glass balls also have the disadvantages of low drawing rate and high drawing cost

Embodiment 1

[0013] Embodiment 1: Take the production of 100kg of high zirconia alkali-resistant glass balls as an example. A. Material preparation: the amount of each raw material and auxiliary material is: quartz sand 56.2kg, of which: S i o 2 ≥99.0%, F e2 o 3 2 o 2 r o 2 65.0%, T i o 2 2 o 3 i o 2 87%, Z r o 2 >1.5%, A1 2 o 3 a O contains 55.7%, S i o 2 e2 o 3 a f 2 2.1kg of 94% fluorite, 27.4kg of soda ash with a purity of 99.6%, and 5.7kg of potassium nitrate with a purity of 99.0%; each component is powder that has been crushed and passed through a 40-mesh sieve;

[0014] B. Initial mixing: Potassium nitrate, fluorite, rutile and other raw and auxiliary materials are mixed into initial mixing materials;

[0015] C. Preparation of mixed material: send the above two primary mixed materials alternately into the mixer and mix evenly, then add 3.0kg of clear water, continue to stir for 3 minutes and then discharge;

[0016] D. Melting molten glass: Send the prepared m...

Embodiment 2

[0019] Embodiment 2: Still taking every production of 100kg of glass balls as an example, the chemical composition of the raw materials and auxiliary materials is the same as in Implementation 1. The raw and auxiliary materials are respectively: 55.1kg quartz sand, 33.5kg zircon sand, 0.5kg rutile, 9.75kg calcite, 2.0kg fluorite, 28kg soda ash and 5.7kg potassium nitrate, mixed with mixed powder, in the process conditions of embodiment 1 Melt down. The produced glass spheres contain Z r o 2 18.5%, T i o 2 1.3%.

Embodiment 3

[0020] Embodiment 3: every production 100kg of glass balls is an example, the chemical composition of raw materials and auxiliary materials and the production process conditions are also the same as in Embodiment 1. The raw and auxiliary materials are: 44.9kg of quartz sand, 24.16kg of zircon sand, 1.8kg of rutile, 6.0kg of calcite, 1.5kg of fluorite, 21.2kg of soda ash, and 4.2kg of potassium nitrate. 75.0kg glass balls), add 26.5kg of its main component Z r o 2 About 17.0% clinker (the amount used to produce 25.0kg glass balls). can be prepared with Z r o 2 17.1%, T i o 2 2.0% alkali-resistant glass balls.

Abstract

The present invention discloses a method for producing an alkali-proof glass ball with high content of zirconia, which adopts quartz sand, calcite, zirconite, rutile, fluorite, niter and calcined soda as the raw materials and the supplementary materials or introduces partial grog to substitute the raw and the supplementary materials. After the raw and supplementary materials are configured into the batch, the batch is delivered to a natural gas melting kiln to be melted, and the alkali-proof glass ball is completed through the cooling, precipitation, ball-making and annealing processing. Since the consumption of the zirconite is increased and the consumption of the rutile is greatly reduced in the powder of the raw materials, and relative craftwork parameters are adjusted, a product meeting the technical standard of the high zirconia alkali-proof glass ball is produced with the present invention. The glass ball that is produced with the method of the present invention has the advantages that the fiber-drawing efficiency can be improved by ten percent, the fiber-drawing cost can be reduced by six to eight percent, the strength retention rate of the glass fiber can be improved by twenty percent or more, the alkali-proof strength is obviously improved, and the service life can reach to 70 years or more when the alkali-proof glass ball is used for producing the glass-fiber reinforced cement products, etc.

Description

technical field [0001] The invention belongs to the production method of alkali-resistant glass balls in the building material industry, in particular to a production method containing high zirconia (Z r o 2 ) method of alkali-resistant glass balls. The glass spheres produced by the method can be used as high-quality raw materials to produce high-performance alkali-resistant glass fibers. Background technique [0002] Alkali-resistant glass fiber, especially alkali-resistant glass fiber with high zirconia content, is a high-quality reinforcing substrate for manufacturing glass fiber reinforced cement products (GRC for short). Because such products have the advantages of light weight, high strength, non-combustibility, strong designability, easy molding, and long service life, the cost is much lower than that of FRP and magnesium cement, and their long-term performance is better than that of magnesium cement. It has been widely used in construction and civil engineering at...
