First, superphosphate cannot be mixed with alkaline fertilizers such as ash, lime, and lime. Because superphosphate contains free acid, it is acidic, and the above alkaline fertilizer contains more calcium. If the two are mixed, it will cause acid-base reaction, reduce fertilizer efficiency, and cause calcium to fix phosphorus, which will cause both losses. Phosphorus ore powder, bone powder and other insoluble phosphate fertilizers can not be mixed with alkaline fertilizers such as grass ash, lime nitrogen, lime, etc., otherwise organic acids in the soil will be neutralized, making the insoluble phosphate fertilizer more difficult to dissolve, and the crops cannot be absorbed and utilized.
Secondly, alkaline fertilizers such as calcium magnesium phosphate can not be mixed with ammonium nitrogen fertilizer. Because the alkaline fertilizer is mixed with ammonium nitrogen fertilizer such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, ammonium nitrate, etc., it will cause and increase the volatilization loss of ammonia and reduce the fertilizer efficiency.
The third is that farmyard manure and other farmyard manure cannot be mixed with alkaline fertilizers such as calcium magnesium phosphate, grass ash, lime ammonia and lime. Because the main component of human and animal excrement is nitrogen, if mixed with alkaline fertilizer, it will neutralize and fail. In addition, the unfertilized farmyard manure cannot be mixed with ammonium nitrate, because the unfertilized farmyard manure can be absorbed and utilized by the decomposition and decaying. If mixed with ammonium nitrate, the unfertilized farmyard manure will dissolve nitrogen during the decomposition process. Loss, so can not be applied, otherwise the nitrogen will be damaged, reducing fertilizer efficiency.
The fourth is that fertilizer cannot be mixed with bacterial fertilizers such as rhizobium fertilizer. Because the fertilizer has greater corrosivity, volatility and water absorption, if it is mixed with the bacterial fertilizer, it will kill or inhibit the living cells and make the fertilizer ineffective.
In addition, ammonia can not be mixed with human excrement, plant ash, potassium fertilizer, ammonium phosphate, potassium chloride, urea, ammonium bicarbonate and the like. Ammonium bicarbonate cannot be mixed with plant ash, human excrement, and potassium fertilizer. Ammonium sulfate cannot be mixed with grass ash or ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia water, etc. In short, in fertilization, farmers should ask more technical personnel to prevent misuse of fertilizer and loss of their crop yield.
Vitrified Grinding Wheels mean grinding wheels in ceramic bonded. Vitrified grinding wheels can be superabrasive grinding wheels like diamond grinding wheel or CBN Grinding Wheels. It also can be abrasive grinding wheels such as white aluminum oxide grinding wheel,pink grinding wheel,silicon carbide grinding.
Vitrified grinding wheel is only one type of bond, which is ceramic, it can be in any type of abrasive.
The main ingredient of vitrified bond are vitreous material with low melting point, such as borosilicate glass, lead glass, etc.It is widely used in various grinding methods such as outer circle, inner circle, flat surface, centerless, etc. It is the most commonly used bonding agent for abrasive tools.
Vitrified bond is characterized by high chemical stability, almost can work in a variety of cooling media, small elastic deformation, brittle, can be made into a variety of hardness levels of grinding tools to adapt to the processing of various hardness of the workpiece. Vitrified bond has good self-sharpening.
The grinding efficiency of single crystal diamond with vitrified bond grinding wheel is higher than metal bond grinding wheel. The wear ratio is very small and the processing cost is low. Therefore, the grinding efficiency of single crystal diamond with ceramic bond grinding wheel can be greatly improved.
