What is the usage process of HDPE bottle recycling machine?

The main recycling of the HDPE bottle recycling machine is to recycle 25% of the recycled materials, such as Post-Consumer Recycled Materials (PCR) and virgin HDPE to produce non-food contact bottles.

What is the production process of HDPE bottle recycling machine?

The production process of the HDPE bottle recycling machine is that the solvent for the polymerization reaction is n-hexane, the catalyst is a highly active z-N catalyst, ethylene and hydrogen are mixed into the first reactor, mixed with the catalyst, and the polymerization reaction takes place. The slurry form is suspended in hexane, the polymerization temperature is about 80°C and the polymerization pressure is less than 10 bar. Products with a density range of 0.942 to 0.965 g/cm3 and a melt index of 0.2 to 80 can be produced with this process. The comonomers are propylene and butene-1, from which traditional HDPE and bimodal HDPE can be made. The performance of high density pipe is excellent, suitable for the production of pressure pipe reaching PE100+.

What Are The Features Of The Production Process Of HDPE bottle recycling machine?

The production process of HDPE bottle recycling machine has low working pressure and low working temperature. the double-vessel reactor can produce unimodal and bimodal products by adopting various forms of parallel and series connection; The process operation is highly flexible, the product brand is changed quickly, and the purity of raw materials is not required. High; propylene and 1-butene are used as comonomers; Hexane is used as a solvent and the recovery unit is simple. A characteristic of this process is that the polymerization is carried out in an inert hydrocarbon diluent.

What is the production process of HDPE bottle recycling machine?

The HDPE bottle recycling machine sends the polymerized ethylene (ethylene 99.9%, ethane 0.1%) to the dryer and then enters the tank reactor along with the circulating n-hexane diluent. The catalyst adopts the carrier containing titanium and manganese, triethyl ether. The base aluminum is the quality of the cocatalyst. A small amount of hydrogen is added to control the molecular weight and the polymerization reaction forms polyethylene particles. The reaction temperature is 90°C and the pressure is 1.8 MPa. The reaction can be carried out in two polymerization kettles in two steps, and the production concentration is 34% (mass fraction). In the slurry solid, the monomer conversion rate can reach 97%. The polymer was flashed from the second reactor to a pressure of 0.14 MPa and the flashed unreacted ethylene, the ethane in the effluent and the 2% cyclohexane diluent were compressed and cooled twice to 2.5 MPa and the Gas has been removed. The stripper recovers the ethane for recycling. The slurry remaining after flash evaporation is centrifuged to recover most of the diluent and the solid filter cake is sent to the dryer to reduce the volatile content to about 5% (wt). The dryer is operated in a closed circuit under nitrogen protection. The dried polymer powder is sent to the fluidized bed for drying to remove any hydrocarbon diluents. After drying, the polymer particles are sent to the mixing section to add various additives, and then granulated.
