Characteristic.
Cobalt powder is gray and irregular, soluble in acid, magnetic, easy to oxidize in wet air. It is widely used in aviation,
aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt based alloys or cobalt containing alloy steels are used as high temperature heat-resistant parts and important metal materials in atomic energy industry as blades, impeller, conduit, jet engine, rocket engine, missile component and chemical equipment of turbine.

As a binder in powder metallurgy, cobalt can ensure the toughness of the hard alloy. Magnetic alloys are indispensable materials in modern electronics and mechanical and electrical industries, which are used to make various components of sound, light, electricity and magnetic materials. Cobalt is also an important part of permanent magnetic alloys. In chemical industry, cobalt isused in high alloy and anticorrosive alloy, and also used in colored glass, pigment, enamel, catalyst and desiccant.
Application
-Water atomized cobalt powder has a relatively coarse grain size, which can be used in welding materials to improve its toughness, impact resistance and wear resistance.
-Reduced cobalt powder is in fine size and high purity, can be widely used in diamond tools, powder metallurgy,

Hot sale Toluene Dissocyanate/TDI

Toluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents. TDI (CAS No. 26471-62-5) consists of two isomers: toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI) (CAS No. 91- 08-7), which is commercially produced in different ratios.

Performance characteristics
1. As a broad-spectrum, long-lasting bactericide to kill many bacteria, fungi and yeasts, the using amount is small.
2. Suitable for use in the medium of the pH value in the range of 2 to 9; free of divalent salt, cross-link no emulsion.
3. Miscible with water; can be added in any production step; easy to use.
4. It has a low toxicity and an appropriate concentration of using, which will lead to no harm completely.
Usage and Cautions
1. In water treatment applications, dilute it into a 1.5% aqueous solution first. Add the solution at a quantity of 80 to 100 ppm for one or two times each week depending on the multiplication of microorganisms like bacteria and algae.
2. Avoid direct eyes' contact with it for a long period. Once the contact happens, rinse eyes with water without delay. No long-term contact with the skin is allowed.
3. Any contact with reducible metals is forbidden during storage, for example, iron and aluminum, so as to avoid decomposition.
4. Not suitable for use in the alkaline medium of pH> 9.0 due to its poor stability. Any combination of this chemical with highly nucleophilic chemicals, like S2- and R-NH2, will lead to declined quality or even complete failure of the product.
