Note: We can supply different size products of pure Fe nanopowder according to client's requirements.
Product Performance
01 Wide temperature range
02 Irregular particles of this powder can effectively absorb medium and high frequency microwaves
03Excellent absorbing performance in the 2-10GHz band


Application of iron powder for wave absorbing shield:
1. Absorbing material: Metal nano-powder has a special absorption effect on electromagnetic waves. Iron, cobalt, zinc oxide powder and carbon-coated metal powder can be used as high-performance millimeter wave stealth materials for military use, visible light infrared stealth materials and structural stealth materials, and mobile phone radiation shielding materials;
2. Magnetic permeability slurry: using the characteristics of high saturation magnetization and high magnetic permeability of nano iron powder, magnetic permeability slurry can be prepared for bonding structure of fine magnetic head;
3. High-performance magnetic recording material: The nano-iron powder has the advantages of high coercive force, large saturation magnetization, high signal-to-noise ratio and good oxidation resistance, which can greatly improve the performance of magnetic tape and large-capacity hard and soft disks.
4. Magnetic fluid: The magnetic fluid produced by iron, cobalt, nickel and its alloy powder has excellent performance and can be widely used in the fields of sealing shock absorption, medical equipment, sound adjustment, light display and the like.

Storage conditions:
iron powder for wave absorbing shield should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.

Acetamiprid is one of the safety Insecticide for agriculture

Insecticide acetamiprid  is an organic compound with the chemical formula C10H11ClN4. It is an odorless neonicotinoid insecticide produced under the trade names Assail, and Chipco by Aventis CropSciences. It is systemic and intended to control sucking insects (Lepidoptera, Thysanoptera, Hemiptera, mainly aphids) on crops such as leafy vegetables, citrus fruits, pome fruits, grapes, cotton, cole crops, and ornamental plants. It is also a key pesticide in commercial cherry farming due to its effectiveness against the larvae of the cherry fruit fly. Insecticide acetamiprid  is an insecticide belonging to the chloropyridinyl neonicotinoids, this family of insecticides was introduced in the early 1990s. This compound is an insecticide that is introduced for controlling pests, but also for domestic use to control fleas on cats and dogs. Mechanism of action: Insecticide acetamiprid  is a nicotine-like substance and reacts to the body in a similar way as nicotine. Nicotine is a n...

Hydroxyapatite - the new century bone

Due to the influence of diseases, aging, frequent traffic accidents and other factors, the number of cases of bone injury has increased year by year. According to statistics, there are 3 million orthopedic cases every year in China, and the demand for bone substitute materials is increasing. In recent years, bone substitute materials represented by hydroxyapatite have gradually become the darling of clinical application. Hydroxyapatite  is a major component of vertebrate bones and teeth and has good biological activity and biocompatibility. Compared with traditional metal (stainless steel, titanium alloy) and ceramic (alumina, silicon nitride) bone substitute materials, hydroxyapatite is not only highly resistant to corrosion and osteoinductive, but also its degradation in vivo is eliminated. The security risks of the former. At present, the research on hydroxyapatite in bone substitute materials mainly focuses on two aspects, hydroxyapatite coating and human bone bionic regenerati...
