Preparation of feedstock containing water-soluble binder for powder injection moulding of silver
نویسندگان
چکیده
Feedstock for powder injection moulding of silver was prepared using water-soluble binder composed polyethylene glycol (PEG) and polyvinyl butyrol (PVB). Silver powders with particle size in range 1 μm to 20 can be mixed PEG/PVB system form feedstocks having loadings 42 vol% 45 vol%. PEG removed water leaching method while PVB by thermal debinding. Specimens retained their shapes during debinding after Components fabricated relatively higher loading resulted density lower porosity. Density specimens containing heated at 700℃ is about 43% 46% the theoretical value, respectively. Therefore, it further developed porous materials applications.

Apparent Wall Slip of Tungsten Carbide Based Feedstock for Powder Injection Moulding
Highly filled polymeric suspensions, such as those involved in Powder Injection Moulding (PIM), exhibit complex rheological behaviour. A detailed understanding of the rheology of these suspensions is prerequisite for their optimum and safe processing. In present paper, rheological behaviour of highly filled WC-Co compounds during capillary flow was studied with emphasis on apparent slip. Contri...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
The effect of powder characteristics on pressure sensitivity of powder injection moulding compounds
Pressure effect on the rheological behaviour of powder-polymer compounds intended for powder injection moulding was determined. A single-piston capillary rheometer modified by addition of a second chamber with a restricting needle valve generating backpressure increasing the pressure in the melted material during the flow through the die was employed to determine pressure sensitivity coefficien...
