Vegetables produced in greenhouses are basically in a closed condition, and the carbon dioxide content in the greenhouse is low, so that photosynthesis is inhibited, so carbon dioxide needs to be added. Tests have shown that cucumber carbon dioxide production can increase production by more than 35%. The leafy vegetables are preferably applied with carbon dioxide in the early stage of growth, and the melons and fruits should be applied from the beginning of flowering. Generally, the carbon dioxide topdressing is carried out at 9-11 am on a sunny day. Carbonammonium + sulfuric acid or baking soda + sulfuric acid can be used to produce carbon dioxide after mixing, so that the carbon dioxide content in the shed reaches 1000 mg/kg. Do not ventilate when applying carbon dioxide. Appropriate ventilation after 1.5~2 hours of application. If carbon dioxide solid particle gas fertilizer is applied, 40 kg per mu is required, which can be directly applied or buried in the surface, and the effective period can be more than 45 days.

CBN is a man-made Superabrasive that outperforms Diamond when used for Ferrous grinding operations.
CBN derives its name from its chemical makeup, of the cubic form of boron nitride (CBN). It has a very desirable characteristic that is sought after when working with difficult to grind (DTG) materials.
Due to its high thermal stability and chemical resistance, the CBN grinding wheel is most suitable for grinding hard ferrous materials, hardened steel, bearing steel, nickel based alloys. machining ferrous materials.
CBN Grinding Wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish.
Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures. When you`re tools become dull over time from use, a CBN wheel will bring them back to its sharp use.
Kemei produce CBN(cubic boron nitride)grinding wheels, which can be resin bonded CBN wheel, metal bonded CBN wheels and electroplated Diamond Grinding Wheels. For same steel parts, you can choose all three types CBN wheels, but there still some difference, if you need more information and the best solutions ,please contact us.
