Low-temperature wheat field in addition to caution
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.

To control grass weeds in wheat fields, common herbicides such as isoproturon, zodiazepam and so on can not be used during cold air activity. Isoproturon will reduce the cold resistance of wheat seedlings, and it is easy for the wheat seedlings to suffer from "frozen phytotoxicity". It is required that frost weather will not occur 1 week after application. In the low-temperature frost period, oxazolyl is applied, and the wheat seedlings are also susceptible to phytotoxicity, and the herbicidal effect is affected. Acetyl oxalate has a wide spectrum of herbicides, wide application period, good mixedness, high safety to wheat, and temperature change does not affect safety. It can be applied from October to April, from wheat 2 leaf stage to jointing Can be applied at any time. In winter, weeding can generally achieve better results with 20% to 30 grams of 15% acetylene oxalate wettable powder per acre.
For the control of broad-leaf weeds, the herbicidal rate is slow in the low temperature period, and the mixing of 2, 4 and 4 chlorine can increase the speed of killing grass, but it is generally not recommended to apply the two when the temperature is too low (less than 5 ° C). medicine. Difluoro-oxazolidine is stable at low temperature, and has stable efficacy even at a temperature of 2 ° C; the drug is suitable for a wide period of time, and can be applied from late November to late January.
