At the time of planting season, seed pesticide soaking is the most commonly used technique in disinfection treatment. The method is simple and saves pesticides. The effect is obvious, but some farmers do not operate properly, but the effect is very small, and it also produces phytotoxicity. The following points:
Grinding Glass Beads, Resistance thermolastic Glass Beads for Grinding Glass Beads for Grinding,Road Marking,Blasting, Glass Beads ,with the advantages of smooth surface, even size, high hardness, wearable and stable, widely used as disperser, grinding media and filler materials in day, paint, ink and chemical industry etc.
Grinding and Polishing Glass Beads :
Size:0.8-1mm;1.0-1.5mm;1.5-2mm;2.0-2.5mm; 2-3mm;2.5-3mm; 3-4mm; 4-5mm; 5-6mm etc.
The ability to operate a mill with smaller-diameter grinding media greatly increases the mill's efficiency and can overall further increase the quality of product through finer grinding. However, smaller Glass beads are more prone to hydraulic packing due to their decrease in mass per bead. Hydraulic packing occurs when the drag flow from the product pulls the media with the product and ultimately causes media packing around the discharge screen.
Glass beads have replaced the conventional grinding media : Ottawa sand, Steel balls, Pebbles, Ceramic balls etc. in Sand mills, Ball mills, Attrition mills for the following simple reasons :
They do not react or get reacted with the materials that are ground.
Being spheres, every bead in charge takes important part in the grinding operation.
They have smooth glassy surfaces and hence slide without much friction there by reducing the load on the stirring mechanism.
Glass beads are of interest to the following industries:
a) Paints. b) Pigments. c) Ink & Printing Inks. d) Dyes. e) Chemicals. f) Cosmetics.

1. Master the concentration of the drug and the time of soaking. The concentration of the drug used for soaking seeds is generally calculated according to the content of the active ingredient of the drug, and there is a certain time requirement. The specific soaking time should be operated according to the instructions for use of the drug. If the concentration is too high or too low, the time is too long or too short, and the drug is prone to occur. Harm or reduce soaking effect.
2. Note the dose of the selected agent. The drug is soaked in a dilute solution of the drug, and the agent used must be dissolved in water. Because the water-insoluble dosage form, the agent floats on the surface of the water or sinks to the bottom of the water, the seed sticking is uneven, and the soaking sterilization effect is not achieved.
3. The soaked seeds should be rinsed and allowed to cool. Seeds with poor tolerance to the drug should be rinsed with water as required to avoid phytotoxicity. If there is no specific explanation for water washing after immersion, it is not necessary to wash it. It should be spread out after washing or immersion. Some can also be directly sown after soaking according to requirements, depending on the type of pesticide and soil moisture.
4. Stir well and the liquid level should be higher than the seed. The seeds should be thoroughly stirred in the liquid medicine to make the seeds and liquids fully contact, and the soaking effect is improved. When the seeds are soaked, the liquid surface is higher than the seeds, so as to prevent the seeds from absorbing water and exposing the liquid to affect the soaking effect.
