deoxidizer must have the side effects of stable reaction, no strange odor and no harmful gas formation. In case of accidental ingestion, it is harmless to human body. Iron powder is the basis of deoxidizer. This material, used in general food, can maintain food quality and prolong shelf life. It can prevent oil oxidation deoxidizer in healthy food. What are the characteristics of deoxidizer material to prevent fading and maintain nutrients. The deoxidizer manufacturer tells you the correct use of deoxidizer.
recommends you to read this article:
riser heating agent supply function. Different risers have different forms, sizes and opening positions, so the design of risers should consider the properties of casting alloys and the characteristics of castings. For alloys with small volume shrinkage (such as gray cast iron) or alloys without centralized shrinkage (such as tin bronze raw materials), the function of risers is mainly to discharge gas and collect liquid from the cavity. For castings requiring control of microstructures, the riser can collect the cooled liquid metal at the front of the flow to avoid supercooling structure on the castings. Fig. 2 is a single cast piston ring, with a small cold on the opposite side of the inner gate. The size and location of such risers should be determined according to the microstructural requirements of the castings."What are the characteristics of the raw materials of deoxidizer" and another article from the manufacturer of composite Deoxidizer will provide some help to you.
