Problems solved by technology

At the same time, the material will be formed into a solid shape, and the overall structure of the material will change after the solid shape is formed. The main performance is: during the cutting operation of the stacker and reclaimer, due to the solid condensation of the material, it will cause the chute to be blocked in the belt conveyor, which will affect the site. Difficulties in production and operation

Embodiment 1

[0024] Adhesive weight percentage is: polyacrylic resin 35%; Polyvinyl alcohol 25%; Orthosilicate ethanol 10%; Water barrier additive (industrial waste oil) 5%; Fast penetrating agent T (sodium succinate sulfonate) 0.5% ; Other water 24.5%.

[0025] Outdoors a surface area of ​​5m 2 On the pile of pellet powder, use the adhesive agent that above-mentioned embodiment is made, the adhesive agent is mixed with 1.5L / m 2 Spray evenly on the surface of mineral powder. In the temperature test, the temperature reached 50°C. After 120 hours, the surface results of the pellet powder were as follows: the surface was well coagulated, with a certain degree of humidity, slightly wrinkled, cracked, and the edges were not loose. Place a fan at a distance of 5-7m from the stockpile, simulate the natural wind force of 5-10m / s, and test the dust suppression rate of 99.8% on the tenth day after spraying. In order to obtain the results of the rain test in a short period of time, artificially sim...

Embodiment 2

[0027] Adhesive weight percentage is: polyacrylic acid resin 30%; Polyvinyl alcohol 13%; Orthosilicate ethanol 20%; Water barrier additive (industrial waste oil) 15%; Fast penetrating agent T (sodium succinate sulfonate) 0.5% ; Other water 21.5%.

[0028] Outdoors a surface area of ​​5m 2 On the pile of pellet powder, use the adhesive agent that above-mentioned embodiment is made, the adhesive agent is mixed with 1.5L / m 2 Spray evenly on the surface of mineral powder. In the temperature test, the temperature reached 50°C. After 120 hours, the surface results of the pellet powder were as follows: the surface was well coagulated, the degree of wetness was obvious, no wrinkling, no cracking, and the edges were slightly loose. Place a fan at a distance of 5-7m from the stockpile, simulate the natural wind force of 5-10m / s, and test the dust suppression rate of 99.5% on the tenth day after spraying, to obtain the results of the rain test in a short period of time, and artificiall...

Embodiment 3

[0030] The weight percent of the adhesive is: polyacrylic resin 25%; polyvinyl alcohol 15%; orthosilicate ethanol 15%; water-repellent additive (industrial waste oil) 10%; fast penetrating agent T (sodium succinate sulfonate) 0.4% ; Other water 34.6%.

[0031] Outdoors a surface area of ​​5m 2 On the pile of pellet powder, use the adhesive agent that above-mentioned embodiment is made, the adhesive agent is mixed with 1.5L / m 2 Spray evenly on the surface of mineral powder. In the temperature test, the temperature reached 50°C. After 120 hours, the surface results of the pellet powder were as follows: the surface was well coagulated, the humidity was moderate, no wrinkling, no cracking, and no loose edges. Place a fan at a distance of 5-7m from the stockpile, simulate the natural wind force of 5-10m / s, and test the dust suppression rate of 99.2% on the tenth day after spraying. In order to obtain the results of the rain test in a short period of time, artificially simulated r...

Abstract

The invention discloses an agglutinant for preventing powdered ore from flying, comprising the following components according to the weight percent: 20 to 35 of polyacrylic resin, 10 to 25 of polyvinyl alcohol, 10 to 20 of ethanol orthosilicate, 5 to 15 of water-resisting agent, 0.3 to 0.5 of rapid penetrating agent and the balance of water. The invention can form a continuous and integrated protective layer, effectively remain the dust on an ore yard, keep the surface humid for a long time and improve the water resisting property, thereby ensuring stable quality of raw materials, lowering the loss of the raw materials and realizing the reutilization of waste. The invention avoids the environment pollution, lowers the working strength of workers and ensures the health of the workers. In addition, the agglutinant has long service life, wide raw material sources, simple formula process, low cost, simple production process, innocuity and no pollution.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive used for ore dust. Background technique [0002] With the improvement of the processing capacity of the material yard of large iron and steel enterprises and the increase of the variety of raw materials, the raw materials are constantly generating dust during the process of transshipment and storage. According to statistics, the proportion of loss caused by external factors such as dust blowing away and rainstorm loss is 5% of the total material every year. These flying dusts are not only unnecessary loss of materials, but also cause immeasurable losses to the environment, working conditions and physical and mental health of employees. [0003] At present, several major environmental polluters in the raw material field are: pellet powder (baqiu powder), Australian powder, coke powder, coal powder, etc. The surface of these mineral powders is easy to dry in the wind and generate dust, a...
