Grapes should be protected after harvest

After harvesting, it is necessary to pay attention to protecting the leaves and enhancing the photosynthetic capacity of the leaves, which plays an important role in increasing the storage nutrients of the trees. In the later stage of growth, it is necessary to strictly control the use of antibacterial and sulfur preparation pesticides. If it must be used together with the new high-fat membrane, improve the utilization rate of the active ingredients of pesticides, improve the control effect and reduce the amount of pesticides to prevent premature aging and reduction of leaves. Photosynthetic efficiency. Under normal circumstances, in addition to the mega-species varieties, the fruit should be used with little or no old leaves after harvesting. When harvesting fruits, it is necessary to pay attention to minimizing the damage to the leaves. After harvesting, it is best to spray new high-fat membranes and tree-protecting generals to control the growth and spread of air-borne viruses, and protect the self-defense reaction instinct of plant trees. The harmful bacteria supply the source, the osmotic elimination of the virus, and the blocking of the virus replication and transmission path. Improve the plant's own immunity, and prevent the harm of sub-health plants to disasters caused by bad weather (frost, sun, hail, rain). Reduce disease recurrence and resurrection rate, and improve plant growth and fruit growth health index. (earth)

PYRITE__As fillers used in grinding wheels/ abrasive tools


Place of Origin: Henan Luoyang, China

Pyrite, Iron pyrites, pyrites lump, Ferro sulphur, Pyrites powder.

Product Description

Detailed introduction:  is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.

Formation of a protective layer 
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.

4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2 
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2 

400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.

FeS2→FeS + S 
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).

(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:


S: 48%min, FE: 42%min, SIO2: 3.0%max, PB: 0.1%max,

ZN: 0.1%max, AS: 0.1%max, . C: 0.3%max, CU: 0.2%max,

H20: 1.0%max, SIZE: 95%min

Granularity: (0-3)mm/(3-8)mm/(3-15)mm/(15-50)mm or other particle size.

Packing: 25KG/500KG/1000KG/BAG or 1000KG/BAG or other packaging.

Note: if there are special requirements, the product can be customized according to clients` requirements.
