Grain filter usage and precautions
Seed impurity removal is an important prerequisite for crops to be highly productive. In the past, due to the limitations of scientific and technological development and other levels, most of the experimenters' methods of removing impurities were manual visual inspection, water selection, and air separation. Not only were the labor costs high, but also time-consuming, labor-intensive, and inefficient, they were also extremely error-prone Affect the accuracy of inspection results. Nowadays, the application of grain sifter in seed decontamination work is significantly higher than the traditional method of decontamination, with extremely efficient design features. The investment and application of this instrument can not only reduce labor costs, improve inspection efficiency, but also Ensure the accuracy of inspection results and promote the development of the grain and oil industry.
The DSX grain filter is developed and produced according to national standards. It is also called a computer filter. It uses a desktop structure and is driven by a high-precision motor. The screen body is supported by a three-point plane and undergoes plane rotation through an eccentric link mechanism. It has a structure Compact and reasonable, stable operation, stable performance, convenient operation and other advantages, the electronic control part adopts single-chip microcomputer to control forward and reverse rotation. The controlled forward and reverse rotation time has high precision, the program performance is reliable, and it can work repeatedly without turning off the power.
The application range of the grain filter is very wide, and now the instrument has been widely used in the food department of acquisition, storage, processing, storage and transportation, scientific research, health, etc., and after the electric filter is matched with the grain selection screen, it is widely used in The screening and determination of grain and oilseeds are necessary screening and grading equipment for agricultural breeding. Of course, as a precise grain quality inspection equipment, the grain filter still needs to pay attention to in operation and use, because the correct use of the instrument is related to the accuracy of the experimental results. The following is a summary of the points for attention when using the instrument, for reference only.
1. The instrument should be placed on a hard working surface in a dry and ventilated laboratory to prevent shaking during work.
2. After putting the sample into the sieve grid and covering the sieve cover, you must tighten the lever to make the sieve layer stable and firmly placed on the tray, and then press the start button. Do not press the start button before tightening the lever or removing the lever .
3. Always pay attention to the set screws at both ends of the three connecting rods to prevent loosening and vibration and noise.
4. Displacement of the connecting rod of the three fulcrums. When the tray is stuck, check whether the six screws on both ends of the three connecting rods are loose, and adjust them one by one.
5. When the gearbox is stuck, send 4 screws in the middle of the tray and 3 screws at the outer end of the connecting rod to adjust the gearbox.
Matting Agent For Elastic Coatings
Introduction:
Soft-touch coatings provide a unique feel, or haptic effect, to surfaces with natural characteristics that tend to be unappealing to most consumers, particularly plastics. They are widely used in interior automotive and consumer electronic applications, where manufacturers seek to provide a premium look and feel to differentiate their products from the competition.
Paint Silica Matting Agent is a very fine-grained precipitated silica as white powder.
Characteristics
High Matting Efficiency;
Excellent Transparency;
Easy to Dispersion;
Excellent Hand-feeling
Applications:
Soft felling coatings used for phone shell, laptop surface, household appliances, plastic electronics and so on.
