Aluminium brazing material production
 
Complex assemblies can be turned into single unit by just one pass through a brazing furnace. Aluminium brazing facilitates the joining of parts with a near-eutectic Ai-Si filler alloy, the liquid temperature which is about 50 ºC lower than that of the core. In serial heat exchanger production the filler alloy is supplied via a thin clad on a core alloy.
 
Compound Material
 
Aluminium brazing material is a sophisticated multi-layer compound consisting of a core alloy which provides the stength and life cycle requirements of the heat exchanger and a clad brazing filler. A one-sided protection layer can also be clad, in order to prevent water-side radiator corrosion.
 
During brazing, only the clad brazing alloy melts, while the core alloys remain solid. The design and the applied materials of the heat exchanger are adjusted to optimize the brazing result regarding the required post braze mechanical properties as well as the corrosion resistance.
 
Roll cladding
 
Today, two basic cladding techniques, roll bonding and cast cladding, have become established industrially. Roll cladding is a solid-state welding process, which is used to join similar and dissimilar aluminium alloys, and represents the primary method of manufacturing fuselage skin sheet for aircraft, bright products and brazing sheet for automotive applications. The cladding layers are attached to the core slab by welding and metallurgical bonding using hot rolling. The cast cladding technique is based on a conventional direct chill mould modified in order to allow multiple metal streams to be casted into one single ingot.
 
Cladding thickness
 
Signi's well established, roll bonding process guarantees tight cladding thickness tolerances, which are essential for ensuring stable brazing results. Rather thin clad layers of 5% can be manufactured, as well as brazing materials also with a cladding thickness of 20%.
 
 

 

Most kinds of plastics could be processed by plastic pyrolysis machines.

the main plastics will be PP PE with high oil output

PVC or PET is not suitable for pyrolysis machines 

there will be Cl generated from its process

when met with water, there will be HCL, 

it is harmful to reactor and all the whole plastic pyrolysis system.

the main process is that by heating the reactor directly, plastics will be pyrolysised into oil gas;

condensers or cooling pipes will cool the gas down into liquid oil with the help of recycling water;

then the rest gas which could not be cooled down into liquid oil will be recycled into reactor heating system; after oil gas coming out completely, stop heating the reactor, and cool down reactor below 70 degrees; then can open the door and discharge carbon black automatically...

there are models with capacities from 5tons to 20tons per batch

LN-2200-6000 capacity of 5-6ton 

LN-2200-6600 capacity of 7-8ton 

LN-2200-8000 capacity of 9-10ton 

LN-2600-6600 capacity of 10-12ton 

LN-2600-8000 capacity of 12-14ton 

LN-2800-6000 capacity of 10-12ton 

LN-2800-6600 capacity of 12-14ton 

LN-2800-8000 capacity of 15-20ton 

if cut into smaller pieces, it could process more.

the whole process includes feeding plastics into pyrolysis reactor;

 then heating the reactor and oil gas coming out for some time;

 cool down the reactor; at last open the door and discharge the carbon blacks...
