Second is the first PET plastic bottle waste on non-PET bottle, seat bottom, label and other impurities mechanically separated, then washed, crushed, granulated. Recycled PET shall not contain PVC impurities, otherwise it will affect the color of PET.

Can be separated by artificial means when a relatively small amount when PVC is mixed on a conveyor belt, namely that when the torque effect of PVC and PET plastic bottles have different melting points in different part of the force will be broken by PET and PVC fragments containing a heater and temperature conveyor control, PVC after being melt-adhered on the conveyor belt, so that the PET can be separated.

Tag beverage bottle after bottle broken can be separated with a blower and cyclone combination device removed. Also preclude the separation means separating column by pumping, crushing PET debris from the top of the vertical separation column, debris countercurrent updraft formed using PET label debris difference in specific gravity, the label is removing, PET separator from the bottom up, in order to guarantee label separation efficiency in production may preclude the use of two or more separate devices.

PET washing debris is very important. 80-100 ℃ washed often preclude the use of hot water to soften or dissolve the adhesive labels and the base of EVA adhesive or other types of adhesive, in order to prevent re-adhesion of the adhesive off the PET flakes, the water required additives, e.g. alkali, emulsifiers or other special chemical agents.


Cleaning fluid is generally determined by the factory waste bottle according to the source and the adhesive properties of the composition and the content of their formulations, recycled washing liquid can be filtered off after reheating impurities, in particular cleaning washing tank equipped with a stirrer were, in order to ensure cleaning effect, washing may preclude use secondary washing process.

Effect of injection molding and blow molding processes: You must ensure uniform thickness distribution of the bottle, get a good stretch, this may form explosive bottles is reduced.
CO2 content is too high: some have been filled soda bottle when the CO2 content, the inner pressure increases with increasing temperature, but PET bottles to withstand the limited capacity (about 10 ~ 20kg / cm2), if the bottle pressure too high, the bottom will accelerate bottle burst occurred in a polar medium effect, generally bottle suitable CO2 content of 4.0 to 4.3 times.
Chain lubricant effect: Because most soft drink production process using chain lubricant, and chain lubricant in contact with the PET bottle a long time, the impact of PET bottles is relatively large. It is therefore crucial chain lubricant selection, which must be dedicated PET bottle lubricant. If the pH is too high chain lubricant (strongly alkaline) or low (strongly acidic) on PET bottles are disadvantageous, preferably close to neutral (pH = 7). PET under basic hydrolysis reaction conditions are likely to occur. Glass and PET bottles for shared lines, since the glass lubricant (pH = 12) pH high, so before into PET bottles, the production line must be cleaned, clean drinking water should be used. When using PET chain lubricant, must strictly follow the concentration provided the use of concentration can not be too high, water thermos bottle machine should be changed frequently in order to maintain a low pH water thermos machine inside.
Dew point temperature: In the summer, air humidity, the higher the dew point temperature, so warm bottle machine speed is not too fast, thermos bottle machine temperature is set too low, thermos bottle outlet temperature above the dew point temperature of the product is easy to 2 ℃, but soda water temperature should not exceed 27 ℃ to avoid affecting the soda taste. If the temperature is below the dew point temperature soda, soda crates, more humid packaging, resulting in the role of chain lubricant in contact with the bottom a long time, prone to burst bottles phenomenon. Particularly the use of shrink film packaging, but also to pay attention to. Water on thermos bottle machine: Experience has shown that, when the high alkalinity of water thermos bottle machine, met consecutive wet summers, it may lead to a large number of PET bottles bottle burst. So we need to reduce the total alkalinity of water thermos bottle machine to 50mg / kg (CaCO3) or less. Soda stack height effects: soda stack height should not be too high, generally 5 boxes per pallet high, stacked two pallets.
Affect the storage environment: soda storage and transportation process not exposure. Soda storage environment should not be too high, generally require storage temperature is below 35 ℃, the product within the storage warehouse should be ventilated, should be kept dry inside the warehouse.

In China and coastal areas south of the Yangtze annual average relative humidity of 85%, in some areas in the spring and summer may be as high relative humidity above 90%, in a high humidity environment, PET hygroscopic maximum saturation humidity.
The higher the moisture content, Ⅳ greater decline in the value of the PET. Take A04,104, it is worth noting that the water content of 0.01%, the intrinsic viscosity of 0.72 and a water content of 0.02% when the intrinsic viscosity becomes 0.63. At 180 ℃ drying time is reduced due 3 / 4h, decreased intrinsic viscosity 0.09.
The longer the drying time, the lower the PET raw material in the water, but can also cause excessive drying PET degradation. When heated to 180 ℃ when, for a maximum initial moisture content of 0.3% of the raw material, fell to 0.14 percent moisture; drying 4h available 0.004% moisture content, which is the upper limit of the preform to control moisture content. 5.2 PET bottle storage and transport
Since PET has performance easily absorb water, therefore preforms, bottles longer storage time will absorb moisture from the air more, so as to gradually reduce the original fine performance. High-temperature, high-humidity environment will directly affect the use of the bottle. Based on the foregoing, we recommend PET bottles in the spring and summer relative humidity ≥85%, ≥35 ℃ lower temperature conditions, the storage period should be controlled within one month; in the autumn and winter, relative humidity <85%, lower temperature <35 ℃ condition storage period should be controlled within three months, the length of the storage period should take account of local weather conditions.
5.3 How to reduce the loss of CO2 PET bottles
(1) CO2 loss pathway PET bottles
By bottle leakage: If the gap between the molecules filled PET CO2 molecule, CO2 molecules will leak out from the bottle, CO2 leakage rate and degree of orientation of biaxially oriented PET, bottle thickness, humidity and pressure.
PET material absorption of CO2: Because porous molecular structure of PET (less dense), making CO2 molecules to penetrate, resulting in absorption phenomenon.

The latter process: The recovery process is the first component of the non-PET PET bottles separated, then crushed recycled. It is the first use of artificial means stone, wood and other plastic products and colored bottles separated. Separation PVC bottles used in artificial selection methods or PVC separation device. Separation of metallic iron can be isolated magnet separator. Beverage bottles through the conveyor into the cleaning machine, bottle vertically into the processing line, in addition to the ring by machine and capping machine in addition to the cap and pull ring removed and weighed to ensure that the cap has been removed, it detected more than the standard weight of a bottle it is separated from the line out. Then injected into each waste PET bottles 100ml boiling water, dissolve the residue drinks bottle, while the bottle was clamped suspended, bottle external high pressure water scrub with hot water to soften the adhesive so that the base off on their own, plastic or paper labels prolapse. After washing the bottom of the bottle after removal, release bottle of water. A process like the first break in the equipment can be, through continuous drier PET bottle flake dried to a moisture content of less than 0.05%. Extrusion granulation end] the same kind of recovery process.
These two recovery technology have factories use. The process is its own characteristics. The first recovery process easier to form large-scale production, but the separation technique is more complex, more separation equipment, large investment. The second method of high purity, using less equipment investment than the province, but only for a complete unbroken bottles, squashed or broken bottles need to separate out separately recovered by other methods. In fact plastic bottles from considerations of economic rationality transport, should be transported flattened after dressing. Second, cut out bottle recycling base essentially as the first approach, a second recovery method therefore more limited. Domestic recycled PET manufacturing colored pesticide, alternative glass to reduce product damage. Foreign manufacturing PET packaging recycling PET. Australia with PET recovered starting material as an intermediate layer three bottles, are widely used in the production of 3-17dtex recycled PET staple fibers.
