Description
Technical field
The present invention relates to PET bottle and reclaim field, specifically PET bottle sheet separate, dedicated metal removes electrostatic discharging opening.
Background technology
Polyester fiber (polyester fibre) by the polyester of organic dibasic acid and dihydroxylic alcohols polycondensation through the synthetic fibers of spinning gained.The polyester fiber PETG of industrial mass production is made, and the commodity of China are called terylene.It is the first kind of current synthetic fibers.PETG is topmost kind in thermoplastic polyester, and English by name Polythylene terephthalate is called for short PET or PEIT (following or be called PET), is commonly called as polyester resin.It is the condensation polymer of terephthalic acid (TPA) and ethylene glycol, is referred to as thermoplastic polyester together with PBT, or saturated polyester.PET is divided into fiber polyester chip and non-fiber grade polyester chip.1. fiber-grade polyester is for the manufacture of terylene short fiber peacekeeping polyester filament, is the raw material of supply polyster fibre enterprise processing fiber and Related product.Terylene is as the maximum kind of output in chemical fibre.2. non-fiber level polyester also has the purposes such as bottle class, film, is widely used in the fields such as packing business, electronic apparatus, health care, building, automobile, and wherein packaging is the maximum non-fine application market of polyester, is also the fastest-rising field of PET simultaneously.The PET production scale of China lags far behind external several main manufacturer.Enter the eighties, China progressively goes abroad the PET resin synthesizer of outer introduction ten thousand tons ~ hundreds of thousands ton advanced person, Quality and yield has had considerable progress, add up according to china textile association, China in 1997 produces PET and cuts into slices 1,740,000 tons, its medium-high viscosity packaging is 22.4 ten thousand tons by (beverage bottle and package sheet material etc.) section production of resins ability, so the resin source producing PET engineering plastics level is sufficient.Because the device preparing various mixture modified PET plastic device and other polymer mixture modifications is general, the manufacturing industry such as domestic mixture extruder take on a certain scale, as long as so market is once developing, the production industry of domestic PET can increase fast.
PETG (PET) is generated by polycondensation reaction by a diacid and a glycol.Terephthalic acid (TPA) two formicester and ethylene glycol is used to produce polyethylene terephthalate as monomer by transesterification and polycondensation reaction in past production practices.But utilize the polycondensation reaction between terephthalic acid (TPA) and ethylene glycol to produce polyethylene terephthalate more and more in production practices now.Reclaiming polyethylene terephthalate is example the most successful and the most universal in polymer recovery.At European PET bottle recovery always in steady growth.Calendar year 2001, have collected 344000 tons of polyester bottles, increased 20% than 2000.By the end of the end of the year 2006, regeneration association will announce Europe 2005 year, and waste PET yield reaches 796000 tons, increases 15.1% than the previous year.The extreme that (regeneration association report, in June, 2006) [5] this waste PET reclaims increases main power is the extensive use of PET, especially in the application of Soft Drinks Plant.An important feature of PET material be it for tissue without any side effect, this is also that bakery and confectionery selects PET material to be widely used in the decisive reason of commodity packaging.Although it is pointed out that PET does not cause environment directly to injure, in view of it account for the sizable part of waste stream, also have the high resistance for air and biotic factor, PET is regarded as deleterious material.Therefore, recycled PET material not only can solve fraction solids waste problem, can also save petroleum chemicals raw material and the energy.
In China, because PET bottle reclaims at the early-stage, various technical research and equipment backwardness relatively, and also consumer is inadequate for the recovery understanding of importance of PET bottle, thus cause being mingled with multiple discarded object in the PET bottle reclaimed, wherein topmost discarded object will count different types of metallic article.In the recovery of PET bottle, the mode mostly adopting section cleaning because batch is clean, therefore, the separation of metal may be selected in section cleaning process, and the metal impurities also not having a kind of effective automation mode can realize in PET sliced materials are at present separated automatically.
