Fertilizers should be used carefully and not mixed without understanding their chemical properties. For instance, farmyard manure, which is rich in nitrogen, should not be combined with alkaline fertilizers like wood ash, lime nitrogen, or calcium-based materials. When mixed, the nitrogen in organic manure can be neutralized by the alkaline substances, reducing its effectiveness.
Similarly, superphosphate should not be mixed with alkaline materials such as grass ash or lime nitrogen, as this can decrease the availability of phosphorus to plants. Insoluble phosphate fertilizers, like rock phosphate or bone meal, also react poorly with alkaline substances. This reaction can neutralize organic acids in the soil, making it harder for crops to absorb the nutrients.
Alkaline fertilizers, such as calcium magnesium phosphate, should not be mixed with ammonium-based nitrogen fertilizers like ammonium carbonate, ammonium sulfate, or ammonium nitrate. The combination can lead to increased nitrogen loss through volatilization, significantly lowering fertilizer efficiency.
Uncomposted farmyard manure should also not be mixed with ammonium nitrate, as the decomposition process may cause nitrogen to escape, reducing the overall effectiveness of the fertilizer.
Moreover, chemical fertilizers should never be mixed with bacterial fertilizers, such as those containing rhizobia. Chemicals are often corrosive, volatile, or hygroscopic, and they can kill or inhibit the beneficial microorganisms in bacterial fertilizers, rendering them ineffective. Always follow proper guidelines when mixing fertilizers to ensure optimal plant growth and nutrient uptake.
Based on the characteristics of electrical accessories and mold working conditions, we will select high-strength, high-wear-resistant, high-heat-resistant mold steel, such as H13, S136, etc., to ensure that the mold Long life and high-precision operation under harsh working conditions. Since electrical parts usually require high-precision machining, our engineering team takes this into full consideration during mold manufacturing and design. The size, shape and surface quality of the mold will be designed accurately.
Our team has extensive experience in electrical parts molds. Whether it is Power Tools Mold, Home appliances mold, or Robot mold, we have invested a lot of energy in creating precision molds so that customers can use our molds to make Products with smooth surface and no burrs. In addition, we also use digital tools such as CAD/CAE/CAM for mold design, simulation analysis and manufacturing planning to estimate the stress distribution, flow behavior, cooling effect, etc. during the molding process, optimize the design in advance, reduce the number of mold trials, and shorten the time development cycle.
