PP particle manufacturers introduced PP plastic particles are high molecular compounds, and their molecular weight is several times or even thousands of times that of ordinary low molecular compounds. Therefore, its molecular motion law is completely different. In crystalline polymers, the transition from solid to liquid is abrupt and readily discernible. In amorphous polymers, this transition is not abrupt and insignificant, and it transitions over a wide temperature range.

  PP granule manufacturersThe production process of PP particles generally has 6 steps.

1. Classify the purchased plastics. There are many types of plastic. General garbage collection station will be coarse classification. However, in order to ensure the quality of the particles, further sorting and processing are required. At the same time, if you want to produce particles of different colors, you need to sort the products by color.

2. PP granule manufacturers: Some waste plastics contain a large amount of impurities during initial washing, such as polypropylene woven bags for cement packaging, polyethylene agricultural mulch film, garbage convenience bags, edible fungus bags, etc. In order to effectively clean up impurities and reduce water consumption, pre-washing is generally used.

3. Crush or crush with water. Generally, some plastics with impurities that are difficult to clean are usually washed with water during the crushing process to achieve the purpose of purifying the plastic. Cleaning plastic generally does not require gouache.

4. Rinse, stir and wash the crushed plastic particles in the pool, and then clean them again.

5. PP granule manufacturers: dehydrate, dry or expose the rinsed plastic to remove moisture (as the case may be).

6. Plastic extrusion, wire drawing, cutting, packaging machine.

PP plastic granules are non-toxic, odorless, tasteless Milky White crystalline polymers. High crystallinity, regular structure, with excellent mechanical properties. In order to let everyone know more about PP plastic particles, today is for everyone. Introduce the physical state of PP plastic particles:

  PP granule manufacturersIntroduction PP plastic particles are high molecular compounds, and their molecular weight is several times or even thousands of times that of ordinary low molecular compounds. Therefore, its molecular motion law is completely different. In crystalline polymers, the transition from solid to liquid is abrupt and readily discernible. In amorphous polymers, this transition is not abrupt and insignificant, and it transitions over a wide temperature range. When the temperature rises to the temperature at which the PP plastic particles can flow freely and become liquid, it is called the melting point Tm. Whenever the PP plastic particles are processed for the second time, the PP plastic particles need to be heated to a high elastic state: and in the three major molding (extrusion, injection molding, injection molding, etc.), the PP plastic particles need to be heated to a viscous flow state.

Plastic is a kind of polymer material, can be made from petroleum ethylene, propylene, styrene and so on. There are many questions about plastic particles.

  PP granule manufacturersThe filling of plastic particles refers to the addition of low-cost fillers (fillers) to the resin. Commonly used fillers include natural minerals, industrial waste, wood flour, nut shell powder, etc. The purpose of filling is mainly to reduce costs for thermoplastic particles, while for thermosetting plastic particles, it is both cheap and modified. Filling can also improve some properties of plastic particles, such as rigidity, heat resistance, dimensional stability, etc., and even improve insulation, flame retardancy, smoke suppression, etc.

PP granule manufacturer: all kinds of waste plastics are automated from cleaning to granulation, automatic feeding when starting up, automatic dehydration during production, automatic rotation of the machine head, automatic temperature control of the main machine, saving electricity, time and large output. After the sorted waste is crushed, it is equipped with some plastic additives, pulled into the stretching machine, cooled with water, cut into particles, dried and bagged. Advanced technology, quality is guaranteed. Welcome friends from all walks of life to inquire.
