Embodiment 1

[0061] The method for preparing novel high-efficiency water-soluble silicon fertilizer by utilizing waste glass fibers comprises the following steps:

[0062] (1) Spray and clean the waste polyester fiberglass. The spray pressure is 0.5 MPa, and the cleaning time is 15 minutes. After cleaning, dry at 80°C for 5 hours. This step is mainly to remove the dirt on the surface of the waste glass fiber;

[0063] (2) After drying, the waste glass fiber is cut into short filaments with a length less than 2mm, and is sent to the airflow vortex pulverizer driven by the airflow. The rotor speed is 3500-4000r / min, and after pulverization, pass through a 200-mesh sieve;

[0064] (3) Mix 200 parts of waste glass fiber powder, 50 parts of malic acid and 300 parts of water after sieving, and react at 85-90°C for 15 hours;

[0065] (4) After 15 hours, it drops below 40°C, add 15 parts of potassium tripolyphosphate, 10 parts of urea, 7 parts of polyglutamic acid, 60 parts of DTPA and HEDTA mixtu...

[0074] The method for preparing novel high-efficiency water-soluble silicon fertilizer by utilizing waste glass fibers comprises the following steps:

[0075] (1) Spray and clean the epoxy resin-type glass fiber waste at a pressure of 2 MPa, and the cleaning time is 8 minutes. After cleaning, dry it at 90°C for 6 hours. This step is mainly to remove the dirt on the surface of the waste glass fiber;

[0076] (2) After drying, the waste glass fiber is cut into short filaments with a length less than 2mm, and is sent to the airflow vortex pulverizer under the drive of the airflow. The rotor speed is 3500-4500r / min, and after pulverization, pass through a 200-mesh sieve;

[0077] (3) Mix 200 parts of waste glass fiber powder, 70 parts of sebacic acid, oxalic acid and succinic acid mixture, and 300 parts of water after sieving, and react at 85-90 ° C for 10 h;

[0078] (4) After 10 hours, it drops below 40°C, add 20 parts of tetrapotassium pyrophosphate, 8 parts of triethanolamine,...

Embodiment 3

[0082] The method for preparing novel high-efficiency water-soluble silicon fertilizer by utilizing waste glass fibers comprises the following steps:

[0083] (1) Spray and clean the acrylate-type glass fiber waste, the spray pressure is 1.5MPa, the cleaning time is 10min, and after cleaning, dry at 90°C for 3h. This step is mainly to remove the dirt on the surface of the waste glass fiber;

[0084] (2) After drying, the waste glass fiber is cut into short filaments with a length less than 2mm, and is sent to the airflow vortex pulverizer driven by the airflow. The rotor speed is 3500-4000r / min, and after pulverization, pass through a 200-mesh sieve;

[0085] (3) Mix 200 parts of waste glass fiber powder, 90 parts of lactic acid mixture, and 250 parts of water after sieving, and then react at 85-90°C for 15 hours;

[0086] (4) After 15 hours, it drops below 40°C, add 20 parts of tetrapotassium pyrophosphate and potassium tripolyphosphate mixture, 10 parts of triethanolamine, 1...

Abstract

The invention relates to the technical field of fertilizer production, and in particular relates to a method for preparing a water soluble silicon fertilizer by utilizing abandoned glass fibers. The method comprises the following steps: (1) cleaning and drying the abandoned glass fibers; (2) smashing the dried abandoned glass fibers, so that glass fiber powder is obtained; and (3) treating the glass fiber powder, so that the glass fiber powder forms a water soluble matter. The method provided by the invention has the advantages that the abandoned glass fibers are taken as a raw material, content of silicon in the raw material reaches more than 60%, a silicon fertilizer which can be easily absorbed by crops is prepared, the problem of treating industrial tailing waste produced during glass fiber production is not only effectively solved, but also a good biochemical environment is created for soil, so that a favorable guarantee is provided for yield increase and high yield of the crops.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a method for preparing water-soluble silicon fertilizer by using waste glass fiber. Background technique [0002] Silicon fertilizer has been recognized by the international soil science community as the next nitrogen (N) and phosphorus (P 2 0 5 ), potassium (K 2 The fourth largest element fertilizer after O). Silicon fertilizer is known as "regulatory fertilizer" and "health fertilizer" because of its miraculous effect on increasing crop production. As a new type of multifunctional fertilizer, silicon fertilizer can not only greatly increase the yield of crops, but also significantly improve the quality of crops (such as insect resistance, disease resistance, and lodging resistance), thus changing the "high yield but not high quality, high quality but not high yield" crops. situation. [0003] At present, the varieties of silicon fertilizer mainly include citr...
