The cleaning fluid may be filtered off and recycled after reheating impurities, in particular cleaning washing tank was equipped with a stirrer, to ensure the effect of cleaning, washing may preclude the two scrubbing process used. PET flakes generally preclude the use of a centrifugal dehydrator enable debris moisture content to 2%, and then by a belt or tube dryer to a moisture content is reduced to 0.5%. Germany Krones successful development of high-quality PET plastic bottle recycling systems, annual processing capacity of up to 15,000 tons PET bottles, the PET raw material after processing can be made directly into other PET containers, the production cost is greatly reduced. PET plastic bottle recycling system to eliminate the use of chemical coating technology to burn alkali chemical coating removing agent to remove the PET plastic bottle surface adhesion of contaminants to achieve any kind of PET plastic bottle recycling. After the technical processing of recycled products, not only production of preforms can be mixed directly, while the recycled products due to low levels of acetaldehyde and yellow pigment, but also to meet the requirements of purity and quality, especially for food and beverage industry products packaging costs 20% -30% lower than the average new material.
Pharmaceutical plastic bottle "Note - blowing" development of molding technology.
I. Introduction
World "Note - blowing" process for forming from the early nineteen fifties. Foreign polyolefin (HDPE, PP) plastic bottles of medicinal use of early seventies. Research related equipment manufacturers United States Wheaton, Jomar, Germany Battenfeld, Bekum, Japan's ASB, solid Aoki, Italy Uniloy Milacron company, the main models are one-step three-position, the United States, Japan screw vertical structure, Germany, Italy adopts horizontal screw configuration.
The introduction of the first batch systems "Note - blowing" assembly line and production of pharmaceutical packaging plastic containers business Tianjin Lisheng Pharmaceutical (1984) and Shanghai Daming Glass Factory (1985). And for China to comprehensively promote the digestion and absorption of polyolefin plastic bottles of medicinal done a lot of basic work.
