Aluminum powder processing method

[China Aluminum Industry Network] The color of aluminum powder is silver white, which is an odorless powder. Its processing methods are as follows:

Melt extrusion

This method is the heat extrusion of the metal pigment and the rest of the powder coating (resin, etc.) through a screw extruder.

2 dry stick method

The method is to add the dry powder of metal pigment into the crushed powder coating and mix it with a mechanical mixer. The advantage of the dry blending method is that the metal pigment and the powder coating are not very intense when mixed, thereby preventing the deformation of the sheet metal pigment and the metal effect is thus not affected.

3 bonding method Bonding-Process)

In this method, the metal pigment and the powder coating are dry-blended while being heated simultaneously so that the temperature just exceeds the softening point of the resin. At this point, the metal pigment can be fixedly bonded to the surface of the viscous resin powder, thereby preventing the powder from being applied and The phenomenon of separation of metal pigments and resin powders during recovery after construction is now the prevailing bonding method.

4、Air flow crushing

The method is based on the principle of supersonic jet crushing. Since the aluminum powder is easily oxidized, it is generally used JZDB series nitrogen protection air jet crusher and classifier for ultrafine aluminum powder production.

Plastic Blind Ditch, main effect is Ooze water in soil. To reduce the pressure of groundwater, eliminate redundant water, protection building won't demage because of Seepage deformation. Widely used in Underground drainage engineering of civil, transportation, water conservancy, civil miners and environmental protection project Underground drainage engineering

 

Product features:

plastic blind ditch is made from many Root modified plastics silk which have same toughness. It is impossible to be staved. With the pressure 250 kpa , Section air void still more than 60%, even on the tremendous pressure, always exist out water space, there are still 10-15% of the pore, and good resilience;

Average surface opening rate of plastic blind ditch reached 90-95%, much more higher than other similar products. To most effectively collecting soil of the seepage, and timely eduction;

plastic blind ditch made by filter membrane from Corrosion fiber and modified polyethylene 3 d mesh, never degradation in in the soil or water, try to be anti-aging formula, can Maintain permanent material without change

filter membrane of plastic blind ditch can be selected according to the different soil conditions, fully meet the needs of engineering, and avoid the old products filter membrane single faults.

plastic blind ditch is light, the construction and installation is very convenient, construction efficiency is greatly accelerated.
