Problems solved by technology

In this invention, the batch material is too high, the melting time of molten glass in the kiln is relatively short, the quality of the produced glass balls is still unsatisfactory, and the clarity of the glass balls is not high; Crystallization and devitrification will affect the ball forming rate of glass balls and seriously affect product quality
In addition, it is obviously unreasonable for the formula of the glass ball to exceed 100% without considering the loss on ignition
At the same time, in the process of using the horseshoe flame kiln to produce alkali-resistant glass balls, the following problems still exist due to the kiln structure itself: 1. Compared with the traditional horseshoe flame kiln, this patent uses high temperature resistant zirconium corundum bricks Or silica bricks are used as the lining, which increases the production cost; 2. Due to the large width of the melting pool, the temperature in the kiln fluctuates greatly, and there is an obvious temperature difference in the width direction of the kiln pool; 3. With the combustion process in the melting pool As the combustion goes deeper, the combustion-supporting force gradually decreases, the flame gradually decays, and the exhaust gas is gradually generated and accumulated due to incomplete combustion, which blocks the small furnace and reduces the production efficiency of glass balls, and the product quality is low, and even reduces the service life of the kiln; at the same time, due to The accumulation of waste gas will also cause environmental pollution
The formula of alkali-resistant glass balls is obviously unreasonable if the sum of each formula exceeds 100% without considering the loss on ignition
In addition, the kiln has a double wall structure and uses non-shrinkage fused zirconia corundum bricks and high-quality silica bricks as the lining or masonry of the melting pool and double walls, which greatly increases the cost compared with the traditional horseshoe flame furnace; As a mixing and combustion area, the small furnace cannot exhaust the exhaust gas, causing the accumulation of exhaust gas in the furnace, affecting the quality of the finished product and reducing the service life of the kiln; and the generation of exhaust gas will also lead to environmental pollution.

Embodiment 1

[0066] A production formula for alkali-resistant glass balls, the raw materials of which include quartz sand, zircon sand, fluorite, potassium nitrate, soda ash, rutile, calcite and slaked lime clinker, based on the standard weight (100kg) of the finished glass ball. On the premise of calculating the loss on ignition, the weight ratio of each component is: 35% of quartz sand, 33% of zircon sand, 3% of fluorite, 2% of potassium nitrate, 30% of soda ash, 4.5% of rutile, and 10 of calcite. The loss on ignition (Loss on ignition, abbreviated as LOI), also known as loss on ignition, refers to the crystal water discharged from the blank during the firing process, and the CO produced by the decomposition of carbonate 2 , SO decomposed from sulfate 2 , And the loss of organic impurities after being eliminated. Relatively speaking, if the ignition loss is large and the flux content is too much, the higher the shrinkage rate of the sintered product will be. The alkali-resistant quartz sand ...

Abstract

The invention relates to a production formula for alkali-resistant glass marble in building material industry, a production method and a production kiln thereof. The invention is reasonable in selecting weight proportions of ingredients, which is favorable for the control of quality system, and the produced finished product of the glass marble has high clarity and good quality; the entire technological process consists of screening, weighting and mixing raw materials, founding and discharging, the technology is simple and the operation is convenient; using a horseshoe-fired furnace for producing the alkali-resistant glass marble solves the technical prejudice in a long term that the horseshoe-fired furnace is unsuitable for the production of the alkali-resistant glass marble; a general glass marble kiln is utilized to realize the production of the alkali-resistant glass marble without improving kiln refractory, which has the advantages of large production scale, easy control and regulation for the production process, good scale effect and prominent energy-saving effect; the cost is dramatically reduced while the production rate is greatly improved in contrast to a full-electric melting kiln.

Description

Technical field [0001] The invention relates to a production formula of alkali-resistant glass balls in the building materials industry, and a production method and production equipment thereof, in particular to a production formula of alkali-resistant glass balls for the production of alkali-resistant glass fibers, and a production method and production use thereof Kiln. Background technique [0002] Alkali-resistant glass fiber is a reinforced base material for manufacturing glass fiber reinforced cement products (GI Qi for short). Because this product has light weight, high strength, non-combustibility, strong designability, easy molding, long service life, and the cost is much lower Glass fiber reinforced plastic, magnesium cement and long-term performance are better than magnesium cement. It is widely used in domestic and foreign construction and civil engineering. It is not only used as a wall material in cold areas, but also extends to some existing product areas usually m...
