Note: according to user requirements of nano particle, we can provide different size products. Product performance: Nano Fe3O4 powder has certain magnetic properties, such as directional movement under external magnetic field, with superparamagnetic when the particle size is within a certain range, and heat generation under external alternating electromagnetic field, its chemical properties are stable, so has wide uses. Application direction: 1. Magnetic seal:Used for precision instruments, precision machinery, gas seal, vacuum seal, pressure seal, etc. Dynamic seal is the most widely used, can achieve zero leakage, with many advantages, such as small amount of sealing fluid, shockproof, no mechanical wear, small friction, low power consumption, long service life, self-lubrication, no aging, wide speed range, simple structure, requirements on the shaft processing accuracy and smoothness is not high, reliable sealing etc. 2. Biomedical field:Magnetic nanomaterials are widely used as carriers of various anticancer drugs to form a magnetic targeted drug delivery system. Magnetic microspheres made of magnetic nanomaterials can also be widely used in the separation of magnetic immune cells, mri imaging and other aspects. Magnetic nanomaterials can produce heat under the action of external alternating electromagnetic field, kill tumor cells, and achieve the purpose of tumor treatment. 3. Magnetic health careIt is reported that the magnetic field has effect on human nervous system, heart function, blood composition, vascular system, blood lipids, hemorheology, immune function, endocrine function. Therefore, it can treat diseases of human body, and have health care effect. Based on this principle, we invented a nano magnetic powder,make the product that added this kind of powder achieves effects, such as adjust human body function, raise disease resistance ability, and have effect of medical treatment health care. 4. With its magnetic properties and dark black color, nano Fe3O4 powder can be used for magnetic recording materials, high-gradient magnetic separators, microwave absorbent materials, special coatings and xerographic developing agents. Storage conditions: This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation. | ||||||||||||||||||||||
