Plastic recycling pelletizing plastic filler masterbatch plants manufacture

Pelletizing process is to grind the powder, after drying, adding adhesive, into good fluidity, particle size of about 0.1mm particles. Generally, the adhesive used should meet the following requirements: there should be enough viscosity to ensure good formability and mechanical strength of the body; After high temperature forging, all volatilization can be achieved, and no residual impurities of adhesive are left in the body. Simple process, no corrosion, no adverse effect on ceramic properties.

Dry molding granulation commonly used adhesives are as follows: (1) Polyvinyl alcohol aqueous solution, the use of this adhesive production process is simple, ceramic porosity is small, the amount of 3% ~ 5%. (2) The melting point of paraffin wax is about 50℃, with thermoplastic, temperature increases, viscosity decreases. When the temperature is higher than its melting point, it can flow and wet the surface of porcelain particles, forming an adsorption layer and playing a role of bonding. Dry pressure is conducive to its cold flow. Paraffin content is usually about 8%. (3) Phenolic varnish, the production process of the adhesive is simple, the mechanical strength of the body is high, and the addition amount is about 8% ~ 15%. (4)Sulfite pulp waste liquid, the formula of this adhesive is: 90% water, sulfite pulp waste liquid 10%, the amount of porcelain powder is 8% ~ 10%, but the green strength is low.

What is plastic pelletizing

Plastic pelletizing is a process of plastic processing, in the process of plastic granulation, according to the performance of the machine and practice, to grasp the skills of plastic granulation, to constantly improve the quality and process of plastic products.

double Stage PP/PE film pelletizing machine / plastic bags granulator line

PE PP Plastic film granulator / waste film pelletizing machine
1. Capacity: 100kg/h-800kg/h
2. Type: Water-ring pelletizing and stand type

Usage of PP PE film pelletizing line/ Plastic film granulator.

This water-cooling single screw plastic pellet making machine is one stage plastic regenerative pelletizer, which is suitable for many kinds plastic waste materials recycling and making pellet, such as PP, HDPE, LDPE, LLDPE Film and clean woven/nonwoven bag materials, etc. The film can be pressed in compressor and then be pelleted.
And also has very developed design, makes sure this machine has a long working life and economical efficiency in using.

Characteristic:
1. Screw and barrel are made of 38CrMoAlA, inlet mouth treated with special alloy: Very strong and long life.
2. Easy operation: It has automatic constant temperature control and stable performance. After adjusting well, 1 or 2 workers are enough to run this machine, to feed the materials and change pellet receiver.
3. Low cost in using after redesign: Now this kind machine is more economic in electric power source and also water. In the long working life of this machine, it can save many sources in energy!
4. High output, long operating life and lower noise: It’s the ideal waste plastics regenerative pelletizer machine for nowadays.

And also there is pvc granulator. It adopts a two-stage planetary extruder, which inherite all the advantages of a planetary extruder 
1.The planetary extruder has a better material adaptability, which can adapt to variety of materials. Also, it can achieve good plasticization effects without replacing any parts.
2.Sufficient degassing performance.
3.The screw is made of material imported from Germany.
4.The scope of application covers almost all heat-sensitive materials such as Rigid and Soft PVC, PVC modified, PVC cable and HFFR cable materials etc.
