The above is the use of carrot herbicides, the use of carrot herbicides. In addition, some carrots and herbicides have been written with chemical herbicides such as: zhongdingling, alachlor, and high-efficiency fluoromethazone.
Alumina Ceramic Structural Parts
Structural ceramics have superior strength, hardness, insulation, heat conduction, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, high temperature strength, etc., so they are high in very harsh environments or engineering applications. Stability and excellent mechanical properties have attracted a lot of attention in the material industry, and its use range has been expanding. The global and domestic industries are increasingly demanding high-precision, high-abrasion, high-reliability mechanical components or electronic components. Therefore, the demand for ceramic products is highly valued, and its market growth rate is considerable.
