Product Industion
Silicon Carbide (SiC) is used quartz sand, petroleum coke (or coal), wood chips as raw material through high temperature resistance furnace smelting made. Silicon carbide is also called moissanite. Silicon carbide devides into Silicon Carbide Sand and Silicon Carbide Fine Powder. The color has green and black.
Black Silicon Carbide containing SiC about 95%, its toughness is higher than Green Silicon Carbide, most of the material used for processing low tensile strength of materials, such as glass, ceramics, stone, refractory, cast iron and non-ferrous metals, etc.
Green silicon carbide containing SiC is about 97% above, good self sharpening, mostly for processing hard alloy, titanium alloy and optical glass, also used for honing the cylinder and fine grinding HSS Cutting Tools.

After the vegetables are grafted, the wind can not be rushed. When the wind is released, it is usually 7-8 days after grafting. When the grafting interface is completely healed, it is necessary to pay attention to the gradual progress when releasing the wind. At first, the ventilation volume should be small, and then gradually increase again. Do not suddenly let the wind out. Second, pay attention to the adjustment of temperature. Strengthen the temperature regulation, keep the daytime temperature at 24 °C ~ 26 °C, reduce it to 14 °C ~ 16 °C at night, keep the temperature difference between day and night at around 10 °C. It is advisable to accept the scattered light at the beginning of the grafting seedling.
In addition, in the case of continuous cloudy days, when the leaves of the plants are seen to be wilting, the speed of the greenhouse temperature should be slowed down. After the leaves of the plants are stretched, the curtains are rolled again, allowing a small amount of light to enter, so repeated until the leaves of the plants Stretched normally.
