Some foliar fertilizers contain humic acid, growth regulators, and physiologically active substances, which have certain effects on improving product quality and increasing yield. However, most foliar fertilizers do not contain fungicides or insecticides, and have no direct preventive effect on infective diseases caused by fungi, bacteria and viruses. However, some foliar fertilizer manufacturers and distributors exaggerate their words in order to obtain higher economic benefits, and they can do everything in their power, such as effective control of blight, rust, smut, soft rot. Disease, Fusarium wilt, Verticillium wilt, etc. Some products are introduced to prevent and control wheat powdery mildew, sheath blight, smut, and dwarf disease in different growing seasons, saying that some pesticides are still more effective than the current ones. It’s better. Here, remind farmers friends that the use of foliar fertilizer should be targeted, to control crop pests and diseases should use the corresponding fungicides and pesticides, do not use foliar fertilizer as a pesticide, so as not to cause losses.
Industrial applications editor broadcast
Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size
