The first order is jdl series parallel twin screw.The twin screw speed , high shear, strong hybrid advantage , make the material fully completed plasticizing mixing , because there is no head back, so that we can arrange for screw combination of different materials and flexible, achieve the best mixing.
In order for the jdl series single screw extruder.Low speed characteristics of the deep groove screw provides processing environment of low shear, at the same time with the barrel cooling, prevent the plasticized material produce the phenomenon of thermal decomposition at high pressure extrusion ;is conducive to the realization of process different, to maximize the advantage of equipment , improve production efficiency;
Suitable for processing all types of heat -sensitive materials , such as pvc, xlpe, low smoke halogen -free flame retardent cables, shielding material.
Techinical characteristic
1ã?�Based formula ingredients:PVC powder,the processing oil(DOP,TOTM,etc.)filling powder(calcium carbonate,etc)additives powder(stabilizer,lubricant,etc)functional powder(flow modifier\flame retardant)
2ã?�Basic processing route
Each material measuring feeding high speed mixer,processed oil twice to join.The blending material added to the double order machine.through single screw granulation ,packaging .choose water strand or air cooling granulating.
3ã?�Application:high and low temperature of PVC cable materials,high flame retardant cable materials,low smoke no halogen cable material,PVC elastomer ,cold-resistant PVC,injection molding grade PVC,etc.c
Technical Characteristic
1ã?�Basic ingredients:resin(PE),crosslinking agent,antioxidant.
2ã?�basic processing route
Each raw material measuring feeding first twin-screw extruder ,plasticizing mixed granulation,Raw materials and products should be good monitoring content of impurities,clasic and control products,More than 10KV products need to be finished in the dust workshop.
3ã?�Application:peroxide crosslinked polyethylene cable materials,etc.
Rubber cushions general used natural rubber and neoprene, requires oil resistant adopt nbr , require resistant high and low temperature adopt silicon rubber, high damping using butyl rubber
Reclaimed rubber granules extrusion machine
Manual specification
1.According plastic variety, formula design and melt index, define extrusion temperature control range and every section temperature.
2.Check extruder section , define equipment normal connect electric.Open water cooling, heating.Wait every section preheat achieve require temperature, check and fasten mould die and bolted connection once more.Stay warm more 10min then add material.
3.Open main machine screw, until rotate normal then open feeding screw , first add less plastic material, notice enter feeding and current situation , wait melt material extrude normal , use hand let extrude material lift then cooling tractor equipment, at the same time open pelletizer and gather product
4.Wait extrude smooth , continue add material , adjustable temperature and craft situation , maintain normal operation.
Configuration:
1.Hydraulic cylinders used for pressuring
2.High-power transmission agent
3.Adjustable rev of mixing shaft
4.Combine the plccontrol and human-machine interface, available to set up many milling modes which can display and memorize the data for each mixing process, as a newly diversifying intelligent type internal mixer which adopts tipper hopper for discharging , so it is convenient to carry out washing and easy to change the formulation, also the process time can be saved by 30%, so it is an ideal choice for rubber&plastic industry.
Chamber volume:35l, 55l, 75l, 110l, 150l
Mixer function:
Put resin, fillers and additive etc into the mixer, through particular shape and relative rotor, under adjustable temperature and pressure airtight condition, contious mixing to polymer.The machine include chamber , rotor , rotor sealing pneumatic pressure device to complete material plasticizing and scattered.Through the discharging device, transmission device to complete the feeding program.
